What Are the Advantages of LED Floodlight? -LED Lighting, High Power LED Lights
The meaning of that statement is pretty clear, the minimum output voltage is the input voltage. So to get less minimum brightness you can either use more LEDs in series or lower the input voltage (or both). Too few LEDs and they might be damaged. The topology probably looks like this (from Wikipedia commons): For minimum output, the switch is always open so the inductor and diode are in series to the output. It's possible the diode is actually another switch1. Powering LEDs with current?What are you planning to do with the LED's? Just light them? Signal coding? BCD display? Check the packaging on the prospective LED's for forward Voltage and maximum current. With appropriate resistance protection, you can easily light them all from a single 6V battery.2. time delayed LEDsHere is one way to do it.The next effect is that the duty cycle on the led goes from 0 to 100 and then 0 and then ....The periods determine how long the 0 to 100 to 0 cycle is. The period differential determines how fast the led goes on and off. You can do that to the other led, either in the same isr or through two other channels3. changing the color on my 12v which base leds?i am not sure why they get warm some thing like too plenty amps could be a reason. the explanation the colour variations is through fact they get warm. while an LED gets warm its resistance variations. which skill they are going to all get extra voltage and so the colour variations4. How can I prevent these LEDs from blinking when turned off?My guess is that you have a dimmer which has a light or LED on it. If this is the case, your particular dimmer does not have a dedicated neutral on it, so in order to power the light/LED, it needs to feed a small amount of current through the lighting circuit. If you had a standard incandescent bulb, this would not be anywhere near enough to cause it to light up, but with CFL's or LED's, this might be enough to cause it to flash. Purchase a dimmer that has a neutral connection on it (usually these are a bit more expensive). Because it can be powered without powering the rest of the circuit, it will eliminate the flashing light5. Getting a more stable signal on very long strips of adressable RGB LEDsseems like you could just feed your data and clock from the middle of the strip and outwards towards the two opposing ends. hopefully your controller has two outputs. this should be achievable with a single pixelpusher if not.6. leds in parallel, switched with NPN transistorsI think it is a reasonable design so far...You need to check that the transistor will cope with the current of 5 LEDs - look up its data sheet and look for peak collector current. If the transistor is OK then you can assume it will switch to virtually a short circuit for the purposes of calculating LED resistor values.To do this you need to know what the forward volt-drop is across the LED for the amount of current you want to put through it. As you are running from 3. 7V to power the LEDs, subtract the forward LED volt drop and what is left will appear across the resistor and transistor - but remember you can probably count on the transistor being a short providing it will handle the overall current from 5 LEDs.Base resistor - the IO pin will want to produce 3.3V and the base will "want" 0.7V BUT, more importantly you will need to inject a few milliamps into the base to properly turn-on the transistor. Assuming it has a current gain of 100 (check the transistor spec sheet) and assuming you want 200mA through the collector from 5 x LEDs, you will need to push into the base a minimum of 2mA - it is a minimum and best go for 5 times this value (10mA).So there is 3.3V from the IO pin wanting to drive 10mA through the base of the transistor which needs 0.7V - this means the volt-drop on the base resistor is 2. 6V. It is passing 10mA so the resistor needs to be 260 ohms - choose 270R or 240 R unless you've got access to a closer range.Power waste is mainly in the resistors in series with the LEDs and the actual power in the LEDs. I do not think there is much you can do about this without running the LEDs from a higher voltage source and putting the LEDs in series.
Twelve Obstacles Restricting the Development of LED Lighting Industry
Twelve Obstacles Restricting the Development of LED Lighting Industry
1. LED color difference problemThere is basically no color difference problem in the application of a single LED, but if many LEDs are put into use together, or a lamp has multiple LEDs at the same time, the color difference problem will pop out. Let's first talk about a group of lamps. If you can see that the colors of the lights are inconsistent at a glance, I think a happy mood will have to be discounted. Although like Luxeon, LEDs are divided into eight military regions according to color temperature, and then divided into several cells on the right in each military region, controlling a wide range of color differences to a certain extent, there are still differences in the same batch of LEDs in the same color region, and this difference still can not escape the provocation of the naked eye.2. Led insulation problem(the insulation here refers to the insulation of the heat dissipation substrate to the positive and negative poles of the LED) I can't say we were the first to find the insulation problem of the LED, but at least the big manufacturers are surprised by our query. So far, in order to solve the fundamental problem, only remedial measures have been taken, such as using aluminum substrate to deal with insulation (the original aluminum substrate was not insulated, but almost all have been done now). It may be incomprehensible to everyone. Single LED is not insulated, which has little impact. There is a problem when multiple LEDs are connected in series.3. Led anti pulse problemThis problem is still controversial with manufacturers. It does exist in my practical application. It is mainly reflected in the cold pulse, that is, the moment of power on, and a few LEDs break down or disconnect at the moment of cold power on. I don't think it is caused by static electricity or high voltage (the starting voltage is within the range)4. Problem of LED luminous angleBecause the LED lens packages of various manufacturers are different, even at the same luminous angle (nominal angle), the effect is also different, which makes the selection of spotlight even more difficult, and it is still not universal.5. Potential blinding hazards of LEDLED lighting points are too concentrated, which makes the center lighting super strong, which is easy to hurt people's eyes. Although some lighting manufacturers make efforts in this regard, due to the lag of laws and regulations, it can only be a moral problem.6. Led heating problemTheoretically speaking, LED is not very hot, but due to the immaturity of current technology, led heating is well known, and I don't want to say more.7. Low led efficiency (luminous rate)At present, the electric conversion efficiency of LED is too low (because there is no instrument test, I dare not give specific data).8. Insufficient LED brightnessDue to the lack of brightness, LED can only act as a supporting role in the lighting industry, mainly for decoration.9. LED light attenuation and service lifeAt present, the problem of LED light failure and service life produced by mainland or Taiwan businessmen is relatively serious. Let's not say more. Major manufacturers such as Luxeon have a nominal 100000 hours. I'm afraid only they have a clear mind. In addition, the quality of heat dissipation solution and the matching of drivers may affect the light failure and service life of LED, so 100000 hours is only a selling point!10. Problems of LED driving power supplyAt present, most of the driving circuits are borrowed from the switching power supply. Of course, there are also very few circuits that are specially used for LED driving, but the effect is basically the same. Because the LED needs DC driving and adopts constant current control, the driving circuit is quite large, which can not be compared with the electronic transformer, and the efficiency is relatively low. It is good to reach 80% (not even a single one). In addition, in order to pursue applicability, manufacturers claim that a driver can bring more than ten random connections (one, two,...). In fact, this is a misunderstanding. Although it is constant current, too high starting voltage will often kill the LED in an instant.11. Limited led shapeDue to the characteristics of LED single-sided lighting, the shape of LED lamps is limited.12. LED unit price is too highMost imported 1w-3w LEDs cost about US $3, and more than 10 domestic ones (poor quality, no intellectual property rights). About six LED lamps are sold to consumers, about 1000 yuan RMB. Do you want to buy color TV sets or lamps.
The Pros and Cons of Low Energy Led Lighting
For most people, probably the biggest single factor against low energy LED lighting as a substitute for the soon-to-be-phased-out regular incandescent light bulb is the cost differential. There is no doubt that an LED equivalent light bulb (for example a 6w LED spotlight as a direct replacement for a 35w GU10 halogen lamp) is significantly more expensive than either the original or a CFL alternative.There are however three important points to bear in mind about the higher price for low energy LEDs as compared to incandescent and energy saving CFL light bulbs.First, the price difference reflects the fact that the use of LED for general purpose domestic lighting is still quite novel, though increasing manufacturing levels and consumer take-up will drive the price down dramatically once both come fully on stream over the coming months.Second, and partially related to the observation above, is that the cost of LEDs drops by a factor of twenty over the course of each decade. This characteristic is reliably predicted by Haitz's Law (very similar to Moore's Law for computer chips and for similar reasons, principally because LEDs are, just like computer chips, pure electronic devices). Haitz also states that LED performance (amount of light per watt of electricity) increases tenfold over the same decade.Third and perhaps most intriguing is the fact that as far as the cost of domestic lighting is concerned, the price of light bulbs is almost entirely irrelevant. It is an extraordinary yet easily provable fact that even if regular light bulbs were totally free and LED lights cost, let's say something outrageous like $80 each, it would still be vastly more economical to purchase LED low energy lights.The reason for this is simple: the cost of electrical lighting is the cost of the energy i.e. electricity. It matters not one jot what the actual light bulbs cost; it's what it costs to run them that really counts. Also, since LEDs last for tens of thousands of hours (in practice, decades of use) you only need to pay the purchase price once, unlike regular bulbs which last only upto two thousand hours or just over one year.The second biggest gripe about low energy LED lighting is light levels and quality, or in technical parlance luminosity and light color.The concern about luminosity stems largely from historical notions of LED lighting applications such as LED Christmas lights and pocket torches which are clearly not capable of providing anything close to useable domestic lighting. However, you could right now purchase one of the latest Sharp Zenigata LED series of light bulbs which is rated at 80 lumens per watt (measure of luminosity).To understand what this means, consider that a standard 40w incandescent bulb delivers about 360 lumens and a 60w bulb about 540 lumens, which gives a ratio of 9 lumens per watt. Anything that offers greater than 25 lumens per watt can be classed as an energy saving light bulb. Zenigata LED light bulbs consume 6.7 watts and thus produce 6.7 * 80 lumens per watt which is 536 lumens, on a par with the standard 60w incandescent light bulb.So you could, right now, replace all your 60w light bulbs with Zenigata LED light bulbs rated at 6.7 watts and consume 1/10th (or 90% less) electricity. And remember Haitz's Law? Because of performance improvements, eighteen months from now you should be able to obtain the same 60w worth of lighting from just 3 watts.LED light, in common with CFLs, has tended to be a somewhat cool blue colour, whereas we are more accustomed to a warmer yellow white colour. This is something that is now commonly addressed with the use of colored phosphors (these do reduce luminosity but this is in turn compensated for by the ever increasing lumens per watt yields for LEDs).The third factor that might be considered to weigh against low energy LED lighting is that the light emitted by an LED is intrinsically directional and doesn't scatter in all directions the way that incandescent and fluorescent lights do. This is actually quite acceptable in a spotlight, flood light or bright reading lamp, but it's not especially effective for emulating general ambient lighting such as a table lamp would provide. Though again, there are LED powered general lighting light bulbs becoming more commonly available that do a reasonable job here.Two obvious plus points for low energy LED lighting are ease of retrofit and ecological credentials (other than simply saving energy).LED lights are widely available for all common base fittings such as mains powered GU10 and 12v MR16 spotlights and the low energy standard base GU24 as well as regular bayonet mounts and Edison screw fittings. LED lights also don't suffer from the many inherent problems associated with CFLs such as: noticeably poor start-up times; reduced lifespan caused by frequent switching on and off; and bulky unattractive bulbs.But perhaps one of the most widely known advantages of low energy LED lighting over energy saving CFL light bulbs is that they don't contain toxic mercury vapour or other unpleasant materials, and thus do not pose a serious health risk or require tiresome and expensive disposal procedures to protect the environment.To sum up, the main perceived disadvantages of domestic energy saving LED lighting are cost and application (luminosity and color). Yet as we have seen, the cost of a light bulb is actually a red herring - the true cost of electrical lighting is the price of electricity and on this score ultra low energy LED lighting puts everything else, including energy saving CFLs, completely in the shade (pun intended).As regards luminosity and light quality, LED lights on balance deliver a cleaner, sharper light than CFL light bulbs and offer far more flexibility in terms of color choice and brightness.Finally, the biggest advantage that low energy domestic LED lighting has over its rivals is that the lighting industry itself regards domestic LED lighting as the future and can barely disguise its contempt for CFLs. Lighting giants such as Philips are on record as stating that they will not invest a single dollar further into CFLs and that their entire research and development efforts are now directed at domestic LED lighting technology.Those who follow eco-technology trends are well aware that there is a world-wide phase-out of incandescent light bulbs already well underway and scheduled to complete within the next couple of years. Given international legislation to ban incandescent lighting and lack of support for the already dated and unloved CFL, it's near certain where the future of lighting lies - with low energy LED light. And as advantages go, I'd say that one's pretty compelling.
Emerson Network Energy Launches LED Lighting System High Efficiency Power Supply Lds100
Emerson Network power is one of the business units of Emerson group (NYSE: EMR). The company, which has been leading the global industry in business critical continuity Ô technology, announced that it has launched a series of high-efficiency power supplies for LED lighting systems. This series of new LED lighting power products with model lds100 have three different output powers of 25W, 70W and 100W, so that OEMs and installation contractors can easily select the most applicable and reliable power supply according to the actual requirements of different applications.Emerson Network Energy's newly launched lds100 series 100W LED power supply has many different product models to choose from, among which model h is suitable for 120v-277v AC input voltage, while model u is suitable for 100v-240v AC input voltage. The model introduced earlier can output 24V DC voltage and 4.1a DC current, which meets the requirements of class 2 output. In addition, there are two modes of constant current output and constant voltage output, so that customers can meet the requirements of different LED lighting systems by using only one product, which helps to reduce the inventory level of manufacturers and customers. The operating range of constant voltage mode covers no-load to full load conditions. Taking lds100-24-h03 as an example, this product has the current limiting function, and its current limiting value can be set through the interface in accordance with IEC 60929. In other words, as long as the standard signal of 0 to 10V is used, the output current can be controlled and the brightness can be adjusted. In addition, the current limit can also be set through the adjustable resistance to facilitate the system design engineer to preset relevant values.All models of Emerson Network energy lds100 series power supply have the active power factor correction function with a rating of no less than 0.9. Therefore, in addition to the regulations of "Energy Star" of the U.S. Environmental Protection Agency, they also comply with the regulations of IEC 61000-3-2 on class C harmonic limit. The conversion efficiency of this series of power supplies is also very high. For example, under the rated AC input voltage of 230V, the efficiency can be as high as 90% (typical value). This high efficiency can further reduce the electricity expenditure of users. If it works at rated power, even if the enclosure temperature of this power supply drops to - 40 ° C or rises to 90 ° C, it does not need to use the cooling fan to dissipate heat, so as to ensure that the power supply itself can still work normally within such a wide temperature range. In addition, the enclosure of this series of power supplies also meets the waterproof grade of IP67. In other words, immersion in shallow water will not damage the power supply. Therefore, it is most suitable for outdoor equipment and instruments installed indoors but with poor working environment. This series of power supplies are small and slim, only 8.5 x 1.65 inches (215 x 42mm) in size and 1.2 inches (30mm) thick, so they can be easily installed in the new generation led lighting system with extremely limited space.The lds100 series power supply of Emerson Network energy not only complies with the provisions of CISPR 15 standard on electromagnetic interference, but also complies with the provisions of section 15 (Part 15) of the Federal Communications Commission (FCC) on conducted noise, so as to ensure that these power supply systems will not have short circuit, overvoltage and overheating. In addition, the lds100 series power supply has successfully passed the test, which proves that its anti surge interference ability meets the test provisions of IEC 61000-4-5 standard on class 3 (model U) and class 4 (model h) installation specifications.The lds100 series power supply complies with the strict provisions of several product safety standards, including the product safety provisions on LED lighting systems such as en 61347-2-13 and UL 8750. In addition, this series of products also comply with CSA c22.2 No. 107.1 and relevant guidelines of CE LVD.The lds100 design platform is highly flexible, allowing customers to quickly make corresponding design revisions according to individual applications.Emerson Network Energy's lds100 series 100W LED power supply has been supplied in batches.
Application of LED Lighting in Stadium Market
The improvement ability and lower cost of LED bring great opportunities for outdoor lighting, especially stadium lighting. In these applications, LEDs can provide brighter and more uniform light and more lighting options than traditional light sources. The three major factors adopted are energy conservation, reduced maintenance costs and lighting aesthetics.Stadiums are indeed the last to stick to the market in turning to LED lighting, mainly because these applications require high-intensity lighting - such as up to 100000 lumens per lamp. Even street lighting requires only 10000 to 20000 lumens per lamp.The two biggest drivers of outdoor LED lighting are sports events and live concerts. "We're a little at a critical point. Some support technologies for LED have only been available for one or two years, so you're only beginning to see major players adopt it now," said Paul Scheidt, head of LED component product marketing at Cree.However, not only in terms of lighting benefits, including energy conservation and reduced maintenance costs. LED provides better lighting for radio and television, improves the viewing experience of HD TV, and provides better special effects, such as slow motion camera playback.In addition to broadcasting requirements, ray chock, senior director of Lumileds business development, said that due to reliability problems, the LED was evaluated as a light source. "When the lights of the 2012 Super Bowl go out for about 30 or 40 minutes, stadium officials are worried not only about one of the biggest sports events to be delayed, but also about the potential responsibility when the lights are turned off for a long time. Usually, traditional light sources need to be cooled before restarting, not like LEDs," chock addedLED manufacturers are ready to meet the high intensity lighting requirements of stadiums and gymnasiums. Here are a few examples of LEDs that can be used in these applications.Cree's XLamp xp-l and XLamp mk-r LEDs are used for stadium lighting. The Cree XLamp xp-l, launched last year, has achieved a breakthrough function of up to 200 lumens / watt at 350 Ma, providing brightness of up to 1226 lumens in a 3.45 mm x 3.45 mm package. Its performance is improved by 50% compared with XLamp XP-G led. Xp-l LED has feature and grading function at 1050 Ma and 85 ° C CRI up to 90 and color temperature from 2700 K to 8300 K.The XLamp mk-r led was introduced a few years ago and provides up to 200 lumens (1 W, 25 ° C) per watt. It is packaged in a 7 mm x 7 mm package with a 6 mm light source and provides brightness of up to 1600 lumens at 15 W, 85 ° C. The mk-r assembly features 85 ° C, provides a color temperature of 2700 K to 7000 K, and provides a minimum CRI option of 70, 80 and 90 (at the selected color temperature).Although older products, Cree mk-r LED is looking for a home in stadium lighting applications. For example, Phoenix University Stadium (Figure 1) Recently, more than 780 metal halide lamps were replaced with 312 Ephesus lighting stadium lamps, including 44928 Cree XLamp mk-r LEDs. The new system uses 310000 watts of energy, which is 75% lower than the 1.24 million watts required by the previous system. The brightness of Ephesus LED lamps is almost twice that of traditional metal halide lamps.Figure 1: 2015 Super Bowl held by the University of Phoenix lights up the stadium with Cree's XLamp mk-r led and Ephesus LED lighting lamps. (provided by Cree)Musco lighting also uses Cree LEDs in a range of indoor and outdoor stadium lighting applications on university campuses.Cree recently introduced xlampextreme high power (XHP) LEDs, with the goal of replacing mk-r for large arrays. Xhp50 and xhp70 LEDs provide twice the lumen output and higher reliability than previous LEDs of the same size.These devices achieve the same brightness by using fewer LEDs, thus reducing the size and cost of lighting system design. This also means fewer optics, smaller PCBs and smaller enclosures. Cree said that XHP LEDs can achieve a longer service life even at higher operating temperature and current than previous led technologies, enabling lighting manufacturers to operate without impact Reduce the size and cost of radiators under the condition of rated life. They can be used for stadium, track and high shed lighting.XLamp xhp50 and xhp70 LEDs provide 19 watts of up to 2546 lumens in 5.0 mm x 5.0 mm packages and 32 watts of up to 4022 lumens in 7.0 mm x 7.0 mm packages, respectively. They provide 2-step and 3-step easywhitebins for 3500 K to 2700 K, 80 and 90 CRI.There is always a trade-off between different LED products in the market. Led selection will be based on the application and what the light source needs to do. For example, although Cree's xp-l and xph70 achieve roughly the same performance, there is a compromise between the lumen of each LED and its impact on optical design. The optical system of xph70 needs to be larger than xp-l, but it provides more lumens, so it needs less total optical system System.Stadium lighting applications require very high intensity. These lamps must project a narrow high-intensity beam at a distance. Scheidt said that the three key factors required to achieve high-intensity light are small light source size, high light output (lumens) and efficient optical design without diffusion or mixing.However, Cree seems to have solved this challenge with the latest single-mode XLamp xp-l high intensity (xp-l HI) led, which has a small light source size. (editor's note: the new xp-l hi LED is expected to be available on digi key when you read this article.)Here are the statistics: xp-l hi is touted as the first single modular led, which can provide more than 100000 candela, 50mm diameter optical elements and 10 watts of power (Figure 2) Based on Cree's SC5 technology platform, it more than doubled the candela of the previous single-chip xp-l led through the same optical elements. It also adopts Cree's new main optical design, which can reduce the light source size by more than 50% and provide candela at 185 watts per watt. The LED can provide up to 90 CRI and color temperature of 2700 K to 8300 K, as well as seek Energy Star certification The lighting manufacturer's xp-l high intensity LED has 6000 hours of lm-80 long-term test data. It also utilizes the existing 3.45 mm x 3.45 mm xp-l package.Figure 2: Cree XLamp xp-l high intensity is the first - die led, which can provide more than 100000 candelas, 50 mm diameter optical elements, 10 watts of power, and 185 lumens per watt at 1 watt hour. (provided by Cree)In order to illuminate the stadium, lighting designers need more intensity directly from the optical elements, such as directly to the stadium. "It's not just about lumens, but how to control these lumens and turn them into candras," said Sheid.This is where the balance is achieved in terms of die size. Scheidt said that larger chips can provide more lumens, but the maximum candela achieved is smaller and requires more power. Candela per watt is the efficiency of LEDs in converting power into strength. Here you can see the advantages of using smaller sources instead of larger sources. Cree's method is to use Single chip packaging makes optical devices easier and more efficient, which can increase the cost.The goal is to reduce the system size, power consumption and cost. Xp-l hi provides 120% more candela than xp-l through the secondary optical system. According to the company, it also achieves 79% power reduction compared with its closest competitors and reaches the same candela level."This will be a major breakthrough in stadium lighting," sheyt said. "When you have to cast a lot of light instead of lumens, candela is the most important. If you can reduce the light to four times the central area or the middle of the football field, radiators, drivers, metals and all the items required for stadium lighting can save a lot of money. “ p>In addition, the light source size of xp-l hi is roughly the same as that of the existing xp-g2 led, which means that it has very good optical compatibility and is suitable for the existing large-scale optical ecosystem.Similarly, Philips Lumileds continues to develop a range of products to meet specific applications such as stadium applications. Chock said that there are three light sources that can produce high-quality stadium lighting lamps - high lumens, high efficiency and color temperature of each transmitter.Lumileds produces 140 lumens per watt at rated driving current, which can be used to create lamps with lamp efficiency of 100110 and 120 lumens per watt. Chock said that due to high efficiency, this saves at least half or more energy than traditional lighting.For example, Luxeon m also offers a variety of CCT and cri options, including 90 CRI products in the range of 5700k, specifically for outdoor areas and stadium applications (Figure 3).Figure 3: Lumileds Luxeon m provides high efficiency and high flux density from a uniform light source through closely related color temperature (CCT) control. (provided by Philips Lumileds)Lumileds also offers an unshown version of Luxeon M. Luxeon MZ provides a small source; it is about 50% smaller than big brother m. This can be converted into a higher candela and better beam control, so it can project light into a very compact beam in the stadium. They provide 900 to 1000 lumens per emitter, about 10% to 15% lower than Luxeon M.In addition to Luxeon m and MZ, another flagship product of Lumileds, Luxeon TX, can use the lumen range in 300 and can be used in stadium applications. "But for stadium lighting with 100000 or 120000 lumens, the size requirements are larger, and you need four times more LEDs than Luxeon m," chock said."Some people may think that Luxeon TX is a better system because the heat is dispersed in a larger area than Luxeon m," chock said. "If you have a very good heat dissipation design, Luxeon m should be enough to optimize the system design and heat density.Although it is not yet used for stadium lighting, chock said that its chip on board (COB) array is another good choice because of their very high light increment (up to 8000 lumens) and very good lumen per watt characteristics.The decision is in the hands of the lighting designer. "Although there is a recommended product, in some cases, different architectural methods can be adopted for some designs, which may lead to different LED choices. However, because Lumileds has such a wide product portfolio, we can provide customers with multiple choices for the same application," chock said. " Lumileds also offers two color LED series for event lighting. These include Luxeon rebel color in 3 mm x 4.5 mm package and Luxeon Z color in 1.6 mm x 1.3 mm size. Luxeon Z is marked by color density, while Luxeon rebel color provides high efficiency."You can install three Z LEDs in one rebel color, but you can get more colors in terms of power watts from rebel color instead of Z," chock saidThere is a trade-off between the two, but equally specific applications, such as lighting a specific space or shooting lights on the stage, will determine the choice.In short, stadium lighting is only the opening of the LED industry, which is a quite new field for LED manufacturers. However, many of them are developing products for specific applications requiring high-intensity light, such as stadium lighting. They also meet the requirements of stadium owners to save energy and reduce maintenance costs, add more excitement to the activities, and Good lighting to improve family viewing.
UL Issued the World's First Safety Standard for LED Lighting Products and Accessories
Underwriters Laboratories Inc. a (UL), a global manufacturer of product safety testing and certification, announced the release of the safety standard ANSI / UL 8750 for LED lighting products. The first edition of the standard creates a global safety standard platform, which will be able to serve all kinds of LED lighting equipment and even the whole accessories supply chain using LED lighting technology. "UL 8750 provides manufacturers everywhere with a much-needed single safety standard to test their LED products and related components sold in the United States." Alberto uggetti, general manager of UL lighting business department, said, "this new standard also gives consumers confidence that those LED products with UL logo have passed the necessary safety tests." For the broad Chinese market, the release of this standard will provide UL with a one-stop solution to domestic LED manufacturers and help them successfully obtain market access in North America. With the promotion of energy efficiency and clean energy by governments, LED technology has become more and more widely used in various lighting products. From general lighting, swimming pool lighting to electronic signal lights and even Festival lights, this low-energy product is gradually changing our life. According to the report of market research firm strategies unlimited, benefiting from the continuous innovation of market technology and the environment of energy conservation and environmental protection, the global LED market is expected to exceed US $5 billion in 2012. This rapid development is also reflected in the Chinese market. China's LED industry has grown rapidly in the past few years. Moreover, with the "ten cities and ten thousand lamps" semiconductor lighting application project promoted by China's Ministry of science and technology nationwide, China's LED lighting market is expected to enter a new development process. However, as LED technology is mostly used in new high-voltage optical output electrical products, its potential safety hazards can not be ignored, such as electrical overheating, electric shock or fire, which may hinder the development of LED technology and expand the field of penetration. Considering this potential risk, the lack of industry standards has become an urgent problem to be solved. To this end, UL specially held a lighting industry summit forum, inviting more than 100 representatives from industry, government, research and testing institutions to conduct in-depth discussions on topics such as LED technology development, future application of lighting design and manufacturing. Thanks to the discussion results of the forum and UL's rich experience in the field of lighting safety for more than 80 years, UL issued three safety standard research outlines in January 2007, and finally issued UL 8750 based on these three outlines. UL has testing capabilities all over the world, and its excellent laboratories can provide customers with product testing services based on UL standards and IEC (International Electrotechnical Commission) standards to help customers gain global market access. In addition, UL is also the only organization with LED energy efficiency test laboratory with national accreditation in the United States. UL is very optimistic about the Chinese market. With its deep global operation experience and strong local service capability, the global certification scheme provided by UL can simplify the testing and certificate issuance process, greatly improve the certification efficiency, and provide guarantee for Chinese manufacturing enterprises to successfully enter the international market. LED technology is an important part of UL's global lighting business. As early as the early 1920s, UL has drafted the first standard for the lighting industry. This standard has been widely used in the history of lamp development and has experienced many changes, such as widely used fluorescent lamps. Today, UL provides testing and certification services for lighting products and their components around the world according to more than 30 safety and performance standards. At the moment when mankind is facing another technological leap, UL will shoulder the responsibility of actively promoting the development of LED technology and strive for safe and energy-saving lighting products.
Qili Optoelectronics Has Developed a Series of LED Lighting Products with Intelligent Integration Te
With senva lighting regeneration technology, chili lighting has developed up to 23 integration technologies and launched a series of LED lighting products with intelligent integration as the main axis, including LED T8 fluorescent lamp and MR16 bulb, which have the advantages of high efficiency, super power saving, long service life and high quality, and have passed BSMI, CE, FCC, RoHS and other certification, It can be widely used in indoor and outdoor lighting environment.In terms of street lamp product line, Qili adopts extremely uniform optical lens and ensures uniform illumination distribution with the optimal design ratio of lamp pole height to street lamp spacing of 1:4. It has developed a very lightweight street lamp with brightness of 160W but weight of only 6kg. At the same time, it can adjust the lighting products within the range of 60W to 200W according to individual needs. At the same time, the tube and panel of LED T8 fluorescent lamp adopt 360 degree full light angle design. The high color rendering index (CRI > 85) is much greater than that of traditional lamp source. There are no light spots and flicker problems. Compared with commercial T8 tubes, the luminous efficiency is increased by 255%, power saving is 60%, and the service life is increased by 6.7 times.Qili led MR16 is produced with the latest Cree XPG / XPE chip. The illumination per meter of 4.6w MR16 is up to 1000 lumens (irradiation angle 25 degrees, 6500k), which can directly replace the 20W traditional MR16 halogen bulb. Compared with the 100W incandescent bulb in the market, Qili 8.5W LED bulb lamp (luminous flux 600LM) saves 91% power and has a service life of more than 50000 hours, which is 50 times that of incandescent bulb, It is expected to replace the application of 27W spiral energy-saving bulb.In addition, Qili also uses RGB color mixing principle and wireless remote control to adjust luminous flux and light color, and develops LED bulb lamps with magic lamp effect. One lamp can switch multiple light colors and have full-color situational illumination, and can also reduce color temperature and brightness to act as night lights; At the same time, the whole series of lamps adopt the constant temperature design of intelligent heat dissipation, and can automatically program-controlled LED constant temperature anytime and anywhere.
Analyze the Development Opportunities and Key Points of LED Lighting
With the improvement of LED luminous efficiency, as a new light source product, LED lighting is popular all over the world. In China, the development of LED lighting has also received strong attention from the government, investment and industry in recent years. Many cities have become semiconductor lighting industry bases, and many big cities actively strive to enter the "ten cities and ten thousand lamps" plan of the Ministry of science and technology. It can be said that China's LED lighting has entered an unprecedented period of development.Seize the opportunity and actively promote the development of LED lightingAt present, the development of China's LED lighting industry is indeed facing a rare historical opportunity.First, energy conservation and emission reduction policies. Worldwide, low-carbon economy has attracted more and more attention, and our government takes energy conservation and emission reduction as an important principle in economic development. The energy consumption of LED is low, and the energy consumption will be reduced by 80% compared with incandescent lamps with the same light efficiency. In addition, LED does not contain harmful metal mercury, which has little environmental pollution. Therefore, LED lighting is of great significance for energy conservation and emission reduction.Second, economic recovery and new industrial growth points that stimulate domestic demand. The global financial crisis in 2008 had a great impact on the global economy. In order to get out of the crisis, the Chinese government successively issued a series of industrial revitalization plans and invested 4 trillion yuan to stimulate domestic demand. The leading role of the government in economic recovery is extremely obvious. It is the common concern of the government and industry to strive to cultivate new economic growth points with market potential and technical connotation. Led itself belongs to the category of high and new technology, and has broad market prospects in the field of lighting in the future. It is estimated that if high brightness LED replaces traditional incandescent lamps, it will reach a huge market scale of more than 300 billion US dollars. Therefore, LED lighting has the basic conditions to become a new growth point.Third, LED technology progress and industrial upgrading have developed very rapidly in recent years. In recent years, LED epitaxial chips, chips, packaging, driving circuits, display applications, lighting control and other related technical fields have developed very fast, and the product cost performance has improved significantly, which brings infinite hope for LED lighting from possibility to reality. At the same time, our government's investment in LED science and technology is also increasing. LED has been supported by the national "863" plan and science and technology support plan. Led basic technology R & D has a very rare development opportunity.Objectively analyze and grasp the key points of LED lighting developmentFirst of all, we should have a comprehensive understanding of the connotation of LED lighting. LED lighting covers LED display applications, landscape lighting, backlight lighting, public lighting, special lighting and general lighting. There are many market segments, industries have different levels, product technologies also have obvious differences, and the application prospect of LED is good. In the field of traditional LED display applications, the market space of full-color display screen is very large, and the market of various display products will continue to grow. In the field of lighting, special lighting applications represented by decorative lamps and street lamps are developing rapidly. The application in the field of general lighting is the future development direction, but it will take time.Secondly, we should objectively analyze the actual technical level of China's LED field. Taking the basic material led chip technology as an example, the overall gap in China is obvious, especially in the technology of high-power products to meet general lighting. However, domestic chip materials should have a good foundation in meeting display applications. The two LED displays in the center of Tiananmen Square on the 60th anniversary of the founding of new China adopt domestic LED materials, and the display effect is good. For the development of LED lighting and application, it can be said that led has been relatively mature and extensive in the field of display application, and there is a lot of room for development and improvement; The application in the field of special lighting has made rapid progress and development is in the ascendant; The application in the field of general lighting has begun, with unlimited prospects and a long way to go.Thirdly, we should make rational layout and steadily promote the development and priorities of LED lighting. In my opinion, in the field of technology, we should increase support for material R & D, especially the high-power chip technology for lighting. In the industrial field, we should pay attention to the market of display application products, landscape lighting, public lighting and so on. In fact, the annual sales scale of LED display applications in China has exceeded 10 billion yuan, the product technology has reached the international advanced level, and the products have a certain export scale. Global high brightness LEDs are widely used in automotive lighting, public signs and signal signs, and building lighting, with a market scale of nearly US $10 billion.
Save Big From LED Lighting Sale
Lighting systems have become an utmost necessity. In fact we can not think of doing without lights, rather staying in the dark. Even our ancestors during the stone age, produced lights by striking two stones. We saw a steady transition in our lighting systems. First we got introduced to the incandescent lights, then we got introduced to fluorescent ones, later on CFLs and LEDs entered the lighting market.Light Emitting Diodes or better known as LEDs are known for being energy efficient semi-conductors. This means that they convert the maximum amount of electricity passed through the diodes into light, instead of heat. LED lighting systems are widely used in commercial sectors, residential sectors and industrial sector.There are various type of led lighting product that are available in the market, like, led bulbs, light panels, flood lights, tube lights, spot lights, and led light bulbs. The reason for the popularity of these lighting products are as follows:With the government emphasizing on the use of energy-efficient lighting products, consumers are also finding it convenient, as these products are helping them to reduce their vitality bill, save energy. But due to the high cost of the light emitting diodes, it is hindering them for its widespread use and also for gaining more popularity. Hence, in order to tide over this inconvenience, lighting manufacturers offer led lighting sale. The sale of lighting products are usually a hit among the consumers. It allows them to buy their desired items at a reasonable price. Rather, one can say at a much discounted rate, from the original rate. The sales are given so that people know how beneficial these lights could be for them.The lighting manufacturers are having retail stores and also sometimes online stores, which provides the consumers with a huge number of benefits during the sale. The online stores are very convenient for those,who want to shop for led products and led accessories but don't have time to visit the store. Just by sitting at their home, they can place orders of the led lighting products or the accessories. The accessories are also a huge hit, as it allows the customers to change to energy efficient lighting just by using the lamp sockets and lighting fixtures, without changing the whole settings of the household.Even the lighting manufacturers have introduced various types of products that can also help them to deal with energy crisis effectively or deal with the consumption of energy effectively. Certain energy saving products like Appliance Power Meter, Automatic Standby Shutdown Device, 30 Minute Rundown Timer Socket, etc are easily available in the lighting market. These products are suitable for keeping a tab on the electricity bill. This is because, these products helps in reducing the energy consumed by the electrical appliances and automatically reducing the electricity bill.Consumers now need not to worry. Even with bright and efficient lighting, now they can reduce the consumption of energy, carbon foot print, heat generation and the best part is to have a reduced vitality bill.
Calculating "net" Energy Cost for Consumers? (Net Might Not Be the Right Word for This Question)?
Why not just look at your utility rates / kwh? 60 w x 24 h = 1.44 kwh. At 15 cents it's 22 cents / day. Oops - that is not eye popping. If the premise being taught is that humans are screwing the planet perhaps you should reconsider that. We are a flea on the hair of a Wooly Mammoth. Global warming has been frustrated by global cooling. Artic ice has grown yet again. Etc. Humans like all life needs energy. Electricity is more efficient than burning forests to cook. Factors for comparisons. Candles really suck for reading. Leaving an incandescent bulb on all the time it will last muuuuch longer than cycling on and off. Those screwy fluorescents are hazardous waste. Price, dimmer (and delayed) output are negatives. LED lighting is the real energy saver. Price is ridiculous as of yet. Banning incandescents caused the manufacturing jobs to be moved to Mexico where they use the bulbs. Reversing the ban did not bring the jobs back. Taxing coal, directly or via EPA regulations, causes jobs to be lost. Meanwhile China has built hundreds of coal fired plants.1. Quantum dot lighting offers new opportunities for low energy lighting systemsLED lighting has advanced considerably in the past few years, but still has problems with the quality of light produced and lighting device control. Quantum dot (QD) technology offers a solution to many of the problems with current LED lighting products. This technology was initially applied to luminous displays and television (video) screens but is being extended to lighting applications. Quantum dots are nano-sized crystals of semiconductor material such as silicon, cadmium selenide, cadmium sulphide, indium arsenide and copper indium disulphide. QDs have the property of luminescence and can emit light of precisely-controlled wavelengths, depending on the size of the nanocrystal. This property forms the basis of QD LEDs used in applications ranging from small indicator lights to large lighting installations. The ability to tune the QD to produce light of a particular wavelength affords a range of possible applications. Quantum dots exhibit both photo and electroluminescence. These are used in different ways to construct QLED devices. The range of wavelengths that can be produced by either method is continuous and any required colour can be produced (see Fig. 1). The output spectrum of a QD device will depend on the physical size of the quantum dot and wavelength increases with physical size, as illustrated in Fig. 1, which shows wavelength compared to dot size for photoluminescence. QDs range in size from 2 to 20 nm (see Fig. 2). Quantum dots may consist of a single material or, more typically, of a core of one material surrounded by a shell of another. An example would be the CdSe/ZnS core shell combination shown in Fig. 3. The addition of a shell around the core material improves the luminescent yield and stability of the QD. Photoluminescence (PL) is the process whereby light energy from a source is absorbed by the quantum dot and then re-emitted at a different wavelength. The property is used in LED devices with a source LED and coating or screen of quantum dots which effectively converts the light from the LED to light of the required wavelength. The required wavelength can be selected by selecting the size of the nanocrystal or its composition. The re-emitted light may be combined with light from the source to provide the required light spectrum. Most QDs have a very broad absorption spectrum and the emitted light is almost independent of the spectrum of the radiated light. QDs show symmetrical and narrow emission spectra and broad absorption spectra under photoluminescence, enabling a single light source to be used to excite multicolour quantum dots simultaneously without signal overlap. QDs have high quantum yields in the visible range (0,65 - 0,85 for CdSe) as well as for the near infrared range (0,3 - 0,7 for PbS, see Fig. 4) . Photoluminescence is put to use by combining a QD layer with a conventional LED source. An example is given in Fig. 5. The QDs are contained in a transparent polymer layer which is either placed separately from the LED or encloses the LED. A high output blue LED would typically be used. The pure and tunable spectra of quantum dots make it possible to achieve excellent color-rendering properties and high luminous efficiency (LE) simultaneously when combining colloidal QDs with light-emitting diodes (LEDs). Colloidal QDs are impractical for fabrication of LEDs due to their solution-based synthesis. QDs must be incorporated into the polymer matrix, and the mixture is dispensed into the LED mould or placed onto the LED to fabricate the QD-LED. In this process, the compatibility of QDs' surface ligands with the polymer matrix should be ensured, otherwise the poor compatibility can lead to agglomeration or surface damage on QDs. Combination of QDs-polymer with a LED chip is a key step converting part of the blue light into other wavelengths of light, to generate white light in the end. A quantum dot LED (QLED) of this type providing a correlated colour temperature (CCT) close to ideal has been fabricated . The characteristics are shown in Fig. 6. Electroluminescence (EL) is a characteristic of a material, typically a semiconductor, which enables it to emit light in response to an electrical current. To enable EL, the quantum dot material must be incorporated into an LED-type structure. In a QD-LED, the material forms part of the LED and a layer of colloidal dots is sandwiched between organic materials (see Fig. 7). The layer is contained in a solid polymer to stabilise and protect the QDs. In its basic form with a single QD layer, the QD-LED is monochromatic. Advanced forms combine QDs using several techniques to produce different colours. The main aim of combining different QDs is to produce light suitable for lighting purposes. Various options have been employed to combine different QDs in the emissive layer of the QD-LED: Mixing different QDs in the QD layer. Inkjet printing a matrix of different QDs in a predetermined manner and ratio. Once all RGB components can be achieved, white emission is also feasible by adjusting the balance between these three constituents. White emission from polymer QD-based LEDs is very attractive, mainly for lighting purposes. For general room lighting, the challenge to obtain low consumption devices combined with the ability to vary the colour temperature of a lamp is the major advantage offered by this type of light emitting device. Moreover, due to the mechanical properties of the organic films, the possibility to achieve very thin and even flexible devices could allow new lighting designs . White light can be produced by a combination of the three primary colours, red, green and blue. In applications relating to human vision, the correlated colour temperature (CCT) and colour rendering index (CRI) are two major concerns of solid-state lighting. The CCT of a white light source is defined as the temperature of a Planckian black-body radiator whose colour is closest to the colour of the white light source. The CRI is a quantitative measure of the ability of a light source to reveal the colours of various objects faithfully in comparison with an ideal or natural light source. It is rated on a scale from 1 - 100. For solid-state lighting applications, warmer white with a colour temperature ranging from 2700 to 3000 K is preferred over bluish white (>5000 K). Conventional LEDs on their own cannot produce white light as light is emitted in a narrow band. We are all familiar with the red, green and blue and other coloured LEDs used in displays and traffic lights, for instance. LEDs are not inherently white light sources, unlike incandescent lamps. Instead, LEDs are functionally monochromatic and emit nearly-monochromatic light, making them highly efficient for coloured light applications such as traffic and instrument lights. However, white light is needed in the lamp to be used as a general light source. White light can be achieved with conventional LEDs in three ways: Phosphor conversion, in which phosphor is used on or near the LED to convert the coloured light to white light. RGB systems, in which light from multiple monochromatic LEDs (e.g., red, green and blue) is mixed, resulting in white light. A hybrid method, which uses both phosphor-converted (PC) and monochromatic LEDs. To produce white light requires all three primary colours. White can also be produced from yellow and blue and this is used in some QD-LED solutions. To create white light with today's LEDs, blue and yellow light are combined by adding a yellowish phosphor-based coating to blue LEDs. Because phosphors have a broad emission range from blue to red, it is difficult to tune the properties of the generated white light. Most solid-state lighting sources consist of a blue inorganic LED backlight coated with yellow phosphor. This produces what is known as "cool white" light, and has a clear leaning towards the blue part of the spectrum. Achieving natural "warm white" requires more red. While these white LEDs suffer from poor color temperature and low CRI (typically 90 while maintaining an efficiency of 65 lm/W. Using QD-LEDs to produce white light suitable for illumination has a number of advantages. The really important properties of quantum dots are colour saturation, colour tunability and colour precision, and these can be used in LED lights to provide incandescent light colour quality. Technically, this translates to a correlated colour temperature of 2700 K and a colour rendering index greater than 90. The direction of research and development is towards lighting based entirely on QD-LEDs. Devices have been produced that combine the required amounts the primary colours from QD-LED to produce light of the required quality. A further development allows the light to be dimmed and the colour bias to be altered by varying the voltage and current of the device. While the photoluminescent property of quantum dot devices can be used in combination with conventional LEDs to produce white light, development seems to be focused on the property of electroluminescence. A combination of inorganic QD layers with organic charge transport layers seems to produce results. It would seem QD based lighting will be the predominant technology of the future, and we can expect more and more products to appear on the market.

How to be a greener teen?Do some research and convince your parents to use LED lighting in their house. It is a good for the environment because they use only a fraction of the power that an incandescent does, and are still much more efficient than CFL bulbs (plus they do not have nasty mercury in them like CFLs). Using LEDs is a good economic decision for your parents, they are more expensive to bu the bulbs, but last several times longer and use less energy for their bill. You will help them save money, and secretly help them save the environment too! Take your time researching price / lumens / watts / color temperature you can find some decently priced bulbs at wal-mart to start, then if you get really gung-ho you can search something like "LED bulub china" in google and find much cheaper bulbs online if you know what to look for, but thats harder to convince your parents about that haha3. Is there a system that would allow me to switch the power source of a device under certain conditions?I doubt the turbine will work--very well.. You would find a Gel Cell battery much better--as a re-charge power supply..useing LED Lighting.
