If an LED is blinking on and off really quick for 5 milliseconds each, will that be dangerous to the LED or not?

No. LEDs are solid state devices, and do not suffer from the thermal shock effects that an incandescent bulb would. This is true even for high output LEDs

Why are H4 LED headlights not designed correctly?

I think you hit it. Cost, most of the LED headlights are made to just pack as many LED as possible into the H4 package as possible, but a small percentage of them are actually designed to mimic the H4 fillament. Most of the cheap LED bulbs are not DOT certified, so look for the certified ones, they give you better performance. I would recommend a brand, but you are already aware of the Phillips.

Directly powering a single 32x16 RGB LED matrix (without external PSU)

I've received yesterday the 32x16 LED matrix I've ordered from AliExpress and I've done some measurements with a multimeter in series with the power wire.LED multiplexing does not seem a good idea as the matrix is already doing that internally.Instead I've found that using the minimum color intensity helps a lot reducing the current usage. E. g. for blue use matrix. Color333(0, 0, 1) instead of matrix. Color333(0, 0, 7); for white use matrix. Color333(1, 1, 1) instead of matrix. Color333(7, 7, 7), etc. With the minimum brightness I've measured:In the average case (not all LEDs are lit) I am getting around 250mA, so I should definitely be fine powering the matrix directly from the 5V pin if I keep the brightness as low as possible

any body have LED circuit runs on 2Nicd cell?

2 NiCd cells are about 2.4-2.6 volts. Most LEDs are about 1.8 to 2 volts. so to run the LEDs at 10ma you would use about a 60 ohm resistor. You need a separate resister for each LED. If the LEDs are rated at much over 2 volts, you can not use them with only 2 cells, you would need a higher voltage. If they are rated at a lower voltage, use a higher value resistor. To get more than 10mA, use a smaller value resistor. 30 ohms would get you about 20mA.

Why do LED lights have a blue tinge to them compared to the normal yellow tinged lights?

If by 'normal' you mean incandescent, the color temperature of an incandescent bulb depends on its design. Most household incandescents have a relatively low color temperature (warm, toward the red/yellow) because filament temperatures are kept low to extend bulb lifetime. Those for special purposes (like photography) have a higher color temperature (cool, more toward blue). LEDs have been designed and built with output all over the visual spectrum and beyond. LEDs use for household space lighting tend to use a blue LED with the addition of a yellow phosphor, using metamerism to give the perception of balanced white light. They are bright because we want them to produce a lot of light, and they do not require a large surface area to do so.

Whenever the voltage on the motor drops, C2 will want to discharge but is forced to do this through the LED's and R./$R = /fracU_B-2×U_LEDI_LED/$

Will LED lighting harm our eyesight?n

Any reports or suggestions that LED lights are harmful to your eyes are little more than fearmongering!Start with the fact that the intensity of sunlight is orders of magnitude higher. Then take into account that LEDs have 0 (zero) emissions below 400nm. UV light is

Is there anyone tell me what is LED flashlights? What flashlights is fit for outdoor survival?

LED stands for light emmitting diode. A flashlight that is LED usually has anywhere from 1 to 6 of the diodes backed up with a mirror finish to project the light. The good part about LED is the batteries last a lot longer. The bad is the light is not as bright

If electricity flows positive to negative, then how can the resistor come before the LED

It does not matter where the resistor is because the LED's voltage drop when on and the driving voltage set the voltage across the resistor. The resistor value sets the current, which controls LED brightness. Kirchhoff's laws of voltage and current, along with Ohm's law are all you need to understand these LED circuits, but without the basic background in EE, it is going to be a challenge. I would suggest starting off with a basic AC/DC circuit analysis text, or using the internet to find the same informatio

How do I create the color purple in an RGB LED (common cathode) using a 555 timer?

As far as I am aware they dont make purple LEDs. Therefore one needs a red and blue one mounted close together to get purple, or as you mention a multi-colour Red, Green,Blue LED with all three colours in the same package. You will have to research the possibilities by looking up the data sheet for the devices involved. Then you need to work out how to use the 555 timer to flash each LED, perhaps alternately, or as a way of altering the brightness or perhaps the voltage applied to the LED. I suggest you experiment and try to do it yourself

what is the exact difference between an "ordinary LED" and an "Amber LED"?

A non-human usage of the word amber is just the name for an orangeish-yellow-like color. Hence an amber LED is just an LED emitting orangeish-yellow light

LED Noob needs help: Plz, I just want something to replace the 60w incandescent bulb in my desk lamp!?

There are certainly different kinds of light bulbs (incandescent, halogen, CFLs, LED's), but there really are not different kinds of Light Emitting Diodes/LED's at retail. A 60 watt-equvalent LED will be a very expensive bulb, likely more than the cost of the lamp you would put it in. To save money, both for the bulb and the cost of using it, check out a CFL OK, what is a "Noob"?...

How do I know if my LED TV screen is bad?

It would help slightly if you stated make and model. If its not OLED then it uses basically a back light LED to light an LCD (liquid crystal display) and that is what you are seeing.Some of the larger screen TV's of this type use something called local dimming, which means the LED backlight panels are in groups so in dark scenes one does not get dark scenes lit. It works to a certain extent but on particularly HDR content the bands are visible.Oled is definitely best at the moment, but only in slightly darker rooms. Other possible problems are Dead pixels Ie elements in the panel that are permanently black or white. Focus issues are seldom a problem with modern LED/LCD sets. If you having issues make sure the Firmware is updated to the latest version Samsung and LG have this in the menu.How do I know if my LED TV screen is bad?.

Voltage divider and LED

Based on what you have drawnIt seems that you want to measure the forward voltage, Vf of the LED segments. Since your LED segment cathodes are connected to ground you only need to measure the anode voltage with your ADC.simulate this circuit - Schematic created using CircuitLabFigure 1. Measuring the forward voltage, Vf, of an LED.Based on what you have writtenI want to measure voltage presence when an led lights up (i.e. the ic_output goes LOW, led is common anode). The -ve of led is connected using a 1k resistor to the output of an IC and ve to VCC.simulate this circuitFigure 2. Measurement for a common anode LED.This assumes that the LED anode is at the same voltage as the ADC Vmax.

Determining the current from an infrared LED used as photodiode

By measuring it. That really should have been obvious.LEDs are not usually characterized as receivers, so you do not have the necessary information to calculate it. Build a test setup and see what you get.You could use a 940 nm photodiode instead of a LED for the receiver. That should come with enough data to calculate the signal. However, even then, there are things in the setup that are hard to know. The photodiode will probably give you a better signal than the LED, but to really know what the level of that signal will be, you need to measure it.

difference between CLF lights and LED lights ?

CFL have glass, mercury, and phosphor. The electronics are somewhat sophisicated, to generate the voltage to create the discharge voltage CFLs make (the discharge exciting the phosphors, which produce the visible light), and because of that emit a bit of RF noise. Most take a bit of time to reach full brightess, and do not like turning off and on in short cycles, and you need dimmer specific models to dim them. They are about 75% efficient compared to standard incandescent. They sometimes do not do so well in the cold. LEDs make the light directly, from energy passing through a specially doped PN, junction, the doping which dictates the wavelength of light created (usually rather narrow). For general purpose lighting, an RGB LED can be used, or more often, the LED is blue/UV, and a phosphor converts its energy into an apparent white light. They may be 90% efficient, compared to standard incandescent. LEDs are easy to get to run off of battery DC directly. Used off off AC, they may have some flicker, and use limiting resistors which throw energy away as heat. LEDs are usually fie with short cylcling, and lower temperatures.

RGB LED strip 100m [closed]

100 Meters of 5050 SMD strip LEDs will require roughly 120-200 amps. However, you cannot drive a 100 meter strip from a single power supply. The thin copper traces in the LED strip can only handle so many amps before they become too hot (your LED strip would melt like ice cream on a hot summer day). This is why led strips are usually limited to 5 meters (5A). You would need separated strips and power supplies for the 100 meters worth. You have the correct idea with your circuit for turning the leds on/off (in fact the wiring is correct) but the transistors you plan on using are the wrong type. To switch the LEDs to ground you would need a low side switch, which would be a NPN transistor. Be careful however, transistors typically switch currents less than 1 amp. For higher power applications I would suggest using a N-channel Mosfet. A quick search on Sparkfun turns up the FQP30N06L, which is capable of handling 30A (with a heatsink, probably less than half without), and is also logic-level, meaning it can be driven with a 5 volt source (Arduino I/O pin). Keep in mind, whatever current your LED strip draws, the ground switch (NPN transistor, N-Channel MOSFET, relay) must be able to handle the same current. Good luck with your circuit!

Is the Traditional Energy-saving Lamp Regulator Used for LED Circuit? Detailed Analysis of 11 Defect
Can the controller of traditional energy-saving lamp act on LED circuit?There are many options for buying LED bulbs, but compatible led dimmers are difficult to choose. Many users will confidently say that it is OK to use the dimmer of traditional incandescent lamps. Now the most commonly seen on the market is thyristor dimmer, which is divided into DC and ac. it is very easy to use in incandescent lamps.After selecting the LED lamp with appropriate color temperature, lumen grade and beam angle, the dimming requirements are met. Different from the random dimming method of ordinary incandescent lamps, dimming LED bulbs with thyristors may be successful, but many problems will occur in most cases.Four conditions:The most common problem is that there is a buzzing beep or a strong stroboscopic. Ordinary incandescent lamps only need to adjust the voltage to adjust the light and shade, but it may not work for LED lamps. We have done experiments and the following four situations have occurred:1. It can't be opened at all. It doesn't light up at all!2. It can only be on at 100% illumination.3. It can work normally, but the buzzing sound is very loud.4. Stroboscopic occurs when it is adjusted to a certain brightness.Dimming principle:During the test, sometimes the LED can be used normally after it is dimmed to a certain limit. We judge that the reason why it doesn't light up is that the applied voltage of the dimmer is too small to reach the required voltage.The internal circuit of LED is much more complex than that of incandescent lamp. The real led dimmer is not only regulating voltage, but also has three principles:1. Wave width control dimming: digitize the square wave of the power supply and control the duty cycle of the square wave, so as to control the current.2. Constant current power supply regulation: the current can be easily adjusted by analog linear technology.3. Grouping control: group multiple LEDs and control them with a simple grouping device.Note the strobe:The reasons for the most stroboscopic cases are as follows: the adjustable resistor itself is not a very reliable component. Often, due to the entry of dust or the lax manufacturing process, there will be an instant jump fault when operating the adjustable resistor, and the light source will flash. Therefore, we need high-quality adjustable resistance, or use linear technology to regulate current rather than voltage.In fact, the internal driving function of LED itself can easily adjust the brightness and darkness, but most LED manufacturers remove this function to save costs. Whether the LED lamp can be dimmed is usually marked on the box. If there is no mark on the box, please use the dimming function with caution or use a special LED dimmer.Dimming will reduce life:A reminder is that dimming can easily reduce the life of the bulb. Why? Simply take a dimming method: we divide one second into 1000 parts, each part is 1 millisecond, and then make the LED light work for 7 milliseconds and turn off for 3 milliseconds through the control chip. In this way, it only works for 0.7 seconds in one second. However, due to the fast flashing interval, we can't feel its brightness flickering with our naked eyes, and we will only feel that its brightness has darkened, which is 0.7 times the original, This achieves the effect of dimming. Similarly, we can achieve 50% brightness, 32% brightness and any brightness. Blink in this way, it's strange not to break early!In order to avoid various problems, try not to use the physical dimming method for the smart bulb. Take out the mobile phone and open the app to adjust the light and shade.In fact, I still like to use the way of grouping device to control the brightness, which is simple, safe and easy to use. It can be easily done by touching the key switch or independent grouping switch. It is not necessary to fine tune the brightness from 0 to 100% perfectly in the home. It is OK to realize several levels of brightness adjustment, which can fully meet the needs.Analysis and retrieval of 11 disadvantages of LED wick:Compared with traditional incandescent lamps, led filament lamps have higher requirements for packaging. It is reported that at present, led filament lamps have very strict requirements for filament working voltage design, filament working current design, LED chip area and power, LED chip luminous angle, pin design, glass bulb sealing technology, etc. it can be seen that the manufacturing process of LED filament lamps is very complex, and there are certain requirements for the financial strength, supporting facilities and technology of manufacturers.In the production process, due to different processes, the requirements for materials are also different. In addition, in production, many equipment need to be transformed according to the performance characteristics of LED filament lamps, which also makes the manufacturers of relevant materials of LED filament lamps miserable. The defects in the bulb material also make the LED filament lamp easy to be damaged during transportation. The complex process and low yield make the LED filament lamp unable to obtain high praise from manufacturers and consumers.1. Difficult process, poor heat dissipation and easy damageAlthough led filament lamps have attracted much attention in the domestic market in the past two years, at present, the problems existing in the production of LED filament lamps can not be ignored: the manufacturing process is difficult, several different processes need to be integrated, and the yield is low; More than 8W led filament lamps are prone to heat dissipation problems; It is easy to be broken and damaged in the process of production and use.2. Structure, performance and price to be improvedDue to the relatively late entry of LED filament lamps into the market, the market-related sharp bubbles, tail bubbles and spherical bulbs are mainly "patch type". In addition, the filament lamps that entered the market in the early stage are far from consumers' expectations in terms of structure, performance and price, which makes consumers have some misunderstandings about led filament lamps. With the breakthrough of key technologies, the maturity of packaging technology and the improvement of bubble sealing technology, the luminous efficiency, finger display, service life and cost of LED filament lamps will be improved to a certain extent.At present, the LED filament lamp needs to be improved in too many places. It is like a newborn "premature baby". It is not very mature in all aspects, with high cost, complex production process and low production capacity. Therefore, we should improve the raw materials, led beads and manufacturing process in the future, so as to improve the production capacity of LED filament lamps, reduce losses and improve delivery efficiency.3. Low power and poor heat dissipation are obstaclesAffected by the production process, there are many problems in LED filament lamps, such as high cost and high damage rate during transportation due to the defects of bulb material. In addition, the heat dissipation of high wattage led filament lamps has also become an obstacle for LED filament lamps to enter ordinary people's homes.Problem 2: high priceAccording to the market survey, the average retail price of a 3W led filament lamp is about 28-30 yuan, which is much higher than that of LED bulb lamps and other lighting products with the same power, and several times higher than that of LED incandescent lamps with the same power. Therefore, many consumers are scared away by the price of LED filament lamps.At this stage, the market share of LED filament lamps is less than 10%. Nowadays, as a characteristic product, led filament lamp restores the luminous feeling of traditional tungsten filament lamp and is loved by many consumers. However, the high cost, low light efficiency and small application range of LED filament lamps are also the problems that lighting manufacturers must face and look directly at in the next stage.1. Supporting materials increase product costThe market prospect of LED filament lamp is very bright, but there are difficulties in the promotion of LED filament lamp at this stage, mainly due to its high cost and the lack of large wattage, which makes the application of LED filament lamp limited to the flower lamp market. In addition, the matching of raw materials also increases the cost, because there is no standard in the specification and shape of filament lamp, and its market volume is small, As a result, the supporting materials are basically customized, and the manufacturing cost remains high.2. The cost of LED filament is too highAmong all parts of LED filament lamp, the highest cost is led filament, mainly because of its complex production process and high cutting cost; The production efficiency is not high and the degree of automation is low, resulting in the cost. At present, the cost of 3-6w filament bulb can be controlled below 15 yuan, of which the cost of LED filament accounts for more than half.3. The packaging of LED filament lamp is exquisiteThe packaging of LED filament lamps is more exquisite. The light effects encapsulated by each enterprise are different. Led filament lamps still have certain limitations in power and heat dissipation, resulting in higher prices than ordinary LED light sources.Problem 3: small marketAt this stage, the power of the best-selling led filament lamp in the market is basically less than 10W, which shows that at this stage, the LED filament lamp is technically trapped in the problem of heat dissipation and can not achieve high power. It also shows that it can only cover a small section of the whole lighting product line and can not be widely promoted. Even if it plays the "nostalgic" brand, the LED filament lamp market is only a small market, It can't become the mainstream for the time being.1. Low consumer acceptanceWith the shrinking incandescent lamp and energy-saving lamp market, LED lighting products are slowly recognized by end consumers. However, at present, the market of LED filament lamps is still very limited. Due to the limited application and power of LED filament lamps, the acceptance of LED filament lamps by end consumers is not very high.In addition, consumers do not know enough about led filament lamps. Many people think it is just an improvement of ordinary incandescent lamps.2. The main demand comes from the projectAs LED filament lamps are mainly used in flower lamps, and their main demand comes from engineering lighting, general dealers will not mainly promote LED filament lamps. Even if a few businesses sell LED filament lamps, they won't have too much inventory.Problem 4: difficult to promoteEntering the terminal market, we can find that the LED filament lamp is not as hot as expected for two reasons:1、 Many stores do not promote filament lamps as key products, and consumers' awareness and acceptance of filament lamps are not high;2、 Compared with LED light source products such as bulb and sharp bulb, led filament lamp products have no qualitative change. On the contrary, the price is relatively high and it is difficult to go. Let alone replace the market position of LED bulb, energy-saving lamp and other products.Therefore, at present, the market advantage of LED filament lamp is not very obvious, and the market is basically waiting and trying.At present, the difficulty of pushing led filament lamps in the terminal market lies in:1、 Poor integration between traditional bubble sealing industry and LED packaging industry (concept and process integration);2、 It is not easy to reverse the concept of end consumers;3、 The acceptance of LED filament lamp products by society and government is not clear. In addition, the price of LED filament lamp is high, and consumers have not really distinguished the difference between LED filament lamp and incandescent lamp, which leads to the difficulty of LED filament lamp market promotion.1. Merchants are not active in promotionAt present, if led filament lamps want to achieve good performance in the market, they also need to strengthen publicity and innovation. The development of LED industry is increasingly fierce, and industry standards have been issued one after another, which has exacerbated the market development resistance of LED filament lamps. Especially at this stage, many consumers do not understand led filament lamps, and merchants are not active enough in promoting led filament lamps. Even most merchants are not very optimistic about their development prospects. In actual sales, customers usually see or ask, Businesses will push this product.2. High price makes promotion difficultAt present, it is difficult to promote LED filament lamps in the market. Because consumers do not know much about led filament lamps, the probability of purchase is very small. In addition, due to the impact of e-commerce, the transaction rate of LED in physical stores is lower. Some consumers pay more attention to the price when purchasing products. Therefore, there is still a long way to go for LED filament lamps to enter the families of ordinary consumers.3. Lack of new selling points of LED filament lampsAt present, led filament lamp is in the primary stage of promotion, and very few people know its advantages because of the appearance and original quality of the product
