Find Answers to the Hottest Questions About Led Light

Do you want to know about led light? Here are some frequently asked questions.

1. When an LED light has a current of 20 amps, that means 20 amps per which unit time?

Correction to Gary: ENERGY USED is a function of time...NOT power. In THIS case, you would take a timer or stop watch, note how long the LED is on, and THEN figure "Joules"...or for a larger unit "Watt-hours". Power is to energy as speed is to distance. Current is to charge as speed is to distance. No one ever speaks of "watts per hour". Watts already contain the per time unit. Watts are Joules per second by definition. Watt-hours or kW-hr are units of ENERGY. The dash means "multiplied by" and remains unpronounced...not "per".

2. How to improve the white LED light efficiency? What are the solutions? - NEWS - Yangzhou Xinghui Lighting Engineering Group Co., Ltd.

a) Enhance the internal quantum efficiency to generate more blue light in the active region and reduce the absorption at the blue output. With the development of epitaxial growth technology and multi-quantum well structure, the internal quantum efficiency of ultra-high brightness LEDs has been very large. Improvement, blue LED has reached more than 90%; b) Improve the light extraction efficiency, adopt the flip-chip structure to avoid the electrode and gold wire of the formal structure to block the light; balance the contradiction between the light absorption and the diffusion current of the transparent conductive film; the bottom reflection layer causes the blue light to reflect in the front light direction; the surface pattern or surface Roughening technology avoids excessive total reflection due to large difference in refractive index; etc.; packaging material close to the refractive index of the chip; c) improving the external quantum efficiency of phosphor photoluminescence conversion, developing phosphor materials and ratios with high photoluminescence conversion efficiency; d) Improve the light-emitting efficiency of the package. The high refractive index of the package material is beneficial to the extraction rate of the chip light, but it also increases the difference in refractive index from the air. For the planar package, it causes the total in-reflection with the air interface. Increasing, thereby reducing the light extraction rate, therefore, a secondary transparent encapsulation layer with a refractive index transition can be considered on the planar package; in addition, for non-planar packaging, the phosphor coating thickness is improved and The shape and the shape of the package structure avoid excessive total reflection of the emitted light due to the large difference in refractive index. The highest light efficiency of blue chip type white LEDs is mainly limited by four parts: 1 The internal quantum efficiency of blue light is estimated to be no more than 90% (under high temperature influence, while low power normal temperature can reach about 95%); 2 The light extraction efficiency of the epitaxial layer is estimated to be no more than 85% (the total reflection angle determined by the refractive index of the material of GaN and silica or epoxy resin in the formal and vertical structures is about 42; the total reflection threshold of GaN and Al2O3 in the flip-chip structure) The angle is about 46; it is estimated that the pattern optimization will not exceed 75); 3 The highest quantum efficiency of blue light converted to white light is estimated to be no more than 70% (see the most efficient lossless single-spectrum 555nm green light, and the photoluminescence efficiency of all blue light converted to 555nm monochromatic green light is less than 78%); 4 Phosphor layer white light out of the ball type package efficiency is not more than 95% (plane package output rate will be much lower, this one is usually less concerned, because light from silica gel or epoxy resin to the total reflection of air The critical angle is only about 42). The integrated optical efficiency of the four parts multiplied is estimated to be no more than 50%; that is to say, the luminous efficacy of the blue chip type white LED does not exceed 340 Lm/W. According to reports, the world's highest luminous white LED is the US CREE company announced in March 2014 that 303Lm / W. It is close to the limit of the estimated white LED efficacy of the above analysis. Progress in Light Efficiency of White LEDs in Silicon Carbide Substrate of American CREE Laboratory China's current domestic LED light efficiency has also gradually caught up with the international advanced level. Many years ago, the Nanchang University team in China used pre-rasterization etching on silicon wafers to alleviate the cracks and dislocation defects caused by the large difference in thermal matching during the cooling process after GaN growth. The key components of MOCVD equipment were improved by special measures. The trachea" to improve the uniformity of GaN growth and other independent patented technology, broke through the key technology of high-efficiency GaN-based blue light-emitting diodes on silicon substrates, and became the third country to master the independent intellectual property rights of blue-light LEDs after Japan and the United States. It broke the situation that Japanese sapphire substrate and American silicon carbide substrate have long monopolized the core technology of international LED lighting, and formed a global three-pronged force with Japanese and American technology. According to the "2018 China Blueprint for the Development of Semiconductor Lighting Industry" released by the National Semiconductor Lighting Engineering R&D and Industry Alliance: "In 2018, China's industrialized white LED light efficiency level reached 180Lm/W,3%,6%". This is commendable, but in the semiconductor integrated circuit industry, 8 inch, 12 inch and other mainstream large-size silicon wafers should be applied to the LED lighting industry on a large scale. At present, the mainstream is still a small size sapphire substrate below 6 inches in the LED lighting industry. When the chain has formed a first-mover advantage, the process maturity and low-cost advantages of the silicon wafer itself cannot be exerted. It is expected that when the industrial chain such as packaging equipment is upgraded to a mainstream with 6-inch or more substrates, the large-volume demand for silicon-based LEDs will continue to return to its original cost less than sapphire and gallium nitride substrates. A lot of advantages, when the market prospects for silicon-based LED applications are very bright. In the early days, because of the low light efficiency of red light, especially green LEDs, the RGB type consisting of three red, green and blue LEDs is limited to display or decorative lighting applications. With the gradual improvement of green LED light efficiency, RGB type White LEDs enter practical lighting. The main advantages of RGB white LEDs are: First, there is no need for phosphors to convert light. This alone can theoretically reduce at least 20-30% of the photoluminescence energy conversion losses in blue chip-type white LEDs; secondly, Easy to adjust color temperature and color, which is very important in smart lighting applications. However, the main disadvantage of RGB white LEDs is that the efficacy of green LEDs is still not high, resulting in a total luminous efficiency that is currently much lower than that of blue chip-type white LEDs; another RGB three LEDs must be strictly matched with luminosity and chromaticity distribution. The light color distribution curve of the three LEDs of red, green and blue should be smooth and completely consistent and the projection direction is consistent, otherwise the luminosity and chromaticity unevenness in different distances and directions are serious; there are also three LEDs of red, green and blue. Three sets of power supply systems complicate the drive circuit and increase the cost. The uneven distribution of luminosity and chromaticity is an inherent defect inherent in blue chip type white LEDs and RGB type white LEDs, but to a different extent. Since the human eye does not perceive the ultraviolet light, the ultraviolet light emitted by the ultraviolet LED chip is absorbed by the red, green and blue primary color phosphors in the package coating and converted into white light, so the ultraviolet chip type white light LED has no chromaticity distribution like the conventional fluorescent lamp. The unevenness of the photometry is also much better than the blue chip type and the RGB type, which is its greatest advantage. The main disadvantage of UV chip type white LEDs is that, in general, when the spectral envelope of phosphor photoluminescence conversion is similar to the continuous spectrum of blue light white light, the ultraviolet chip type white light LED has higher luminous efficiency than the blue chip type. Low, the shorter the ultraviolet wavelength, the lower the conversion efficiency (the light conversion efficiency of the phosphor under 254 nm ultraviolet light does not exceed 50%), and the manufacturing difficulty is multiplied, so it is theoretically impossible to use the short-wave ultraviolet chip for illumination. Make white LEDs. In addition, high-efficiency phosphors for long-wave UV excitation are needed. Moreover, the author suggests that the spectrum emitted by the phosphor after conversion should be like the three primary colors of the energy-saving fluorescent lamp, such as red, green and blue, forming a discrete discontinuous spectrum, each of which is a narrow spectrum, and the green peak should be close to the highest light efficiency of 555 nm. The green light with red and blue light may easily exceed the limit light efficiency of the 340 Lm/W blue chip type white LED. Of course, even if the phosphor can do this, the current half-width of the light-emitting wavelength of the LED chip is not too wide, and the 254-nm working ultraviolet light generated by the low-pressure discharge in the conventional fluorescent lamp cannot be matched with the phosphor by its very narrow wavelength half-width. The effect may still be poor.

The Lighting Trinity: 3 Specs You Must Know When Purchasing LED Light Bulbs
Shopping for lighting used to be pretty easy. For most bulbs, you only needed to know the physical shape and the wattage. For something more exotic, you could bring your old bulb to the store and match it with something on the shelf.It's very easy to purchase the wrong bulb - and end up dissatisfied.Today, light bulb shopping is a convoluted mess. The wattage is no longer tied to how bright the bulb is. There are a bunch of new terms, like Kelvin, CRI, and lumens. It's very easy to purchase the wrong bulb - and end up dissatisfied.But it doesn't have to be difficult. I'm going to explain the three specs you need to know in plain English. I call these the Lighting Trinity. And I'll show you how to find this information on light bulb packaging.1. Correlated Color TemperaturePut simply, correlated color temperature (CCT) is the color of white light.Forget descriptions like "soft white" and "daylight." Those are misleading. Instead, you'll want to know the actual value associated with CCT.A classic 60 watt incandescent bulb is about 2700 K at full brightness.CCT is expressed in degrees Kelvin, often shortened to K. You'll typically see numbers like 2700 K and 5000 K written on lighting packaging. The lower the number, the "warmer" the color. 2700 K might be described as warm white and 5000 K may be considered cool white.A classic 60 watt incandescent bulb is about 2700 K at full brightness. A halogen lamp is about 3000 K. When dimmed, both may fall to 2000 K, or even lower. This is the type of lighting typically found in a home.Fluorescent lamps are trickier. They can come in a variety of color temperatures. Commonly, you'll find 3500 K, 4100 K, and 5000 K, but lower and higher values are also available. Office lighting is typically around 4100 K.The Lighting Facts label, found on most consumer lighting products, will help you find the right CCT. The number will be under "Light Appearance" or "Light Color". Some brands, like IKEA, publish CCT and other information on the packaging but do not use the Lighting Facts label.2. LumensLumens are effectively the brightness of a white light source.You'll see a lot of bulbs advertised with terms like "60 W Equivalent." Oftentimes, these statements are downright false. Instead, pay attention to lumens, which you'll also find listed on the Lighting Facts label.As an example, there are a number of "60 W Equivalent" bulbs that actually have lumens closer to a 40 watt bulb. Talk about disappointment.When replacing incandescent bulbs, use these lumen values to find an LED equivalent:40 watt: 400 lumens60 watt: 800 lumens75 watt: 1100 lumens100 watt: 1600 lumens150 watt: 2200 lumensSo, when you are looking for a 60 watt replacement, look for something with a brightness of about 800 lumens.3. Color Rendering IndexColor rendering index (CRI) is a measure of how "real" or accurate colors look under a white light source.CRI values range from 0 to 100. For most applications, the higher the CRI, the better.Consider the appearance of people and objects under daylight. They tend to look great, right? Well, the CRI of daylight is around 100. Contrast this to an orange street light, where it's hard to discern the color of anything. That street light has a CRI close to 0.Classic incandescent light bulbs have a very high CRI of about 100. Most LEDs sold today are around 80 CRI, but the state of California requires vendors to sell bulbs with a CRI of 90 or higher.The tricky part is that manufacturers do not have to specify CRI on Lighting Facts labels. Sometimes you'll see it printed somewhere else on the box. For example, IKEA always prints CRI on LED bulb packaging. Products with 90 CRI and higher almost always mention CRI on the packaging.But often, CRI is nowhere to be found. A good rule of thumb: if CRI is not specified and the bulb is from a name brand like Philips, GE, or CREE, it is probably about 80 CRI. If you don't recognize the brand and it is low-cost, it may be in the range of 70-80 CRI.You will probably find an 80 CRI bulb acceptable if it meets your CCT and lumen requirements, but try to get something with a higher CRI, if available.Wrapping UpNow that you have an understanding of the Lighting Trinity, let's put your knowledge into action.Say you want something to replace your 60 watt incandescent bulb, which has a CCT of 2700 K and 800 lumens of brightness. Get an LED bulb that is about 2700 K, produces around 800 lumens, and has at least 80 CRI.You might want something a little brighter or a little cooler. Use your understanding of color and brightness to pick, respectively, a higher lumen value or higher CCT.If this is too much to process, or you've got an unusual light bulb, be sure to head over to SimpleBulb.com.

What Are the Pros and Cons of Energy Saving Light Bulbs?
i ought to provide you with experts and cons, yet your question requested for a third important factor. perchance that ought to nicely be "What the way ahead for bulbs sounds like". i am no longer an expert, inspite of the undeniable fact that it form of feels to me the technologies for LED lights is catching up quick. perchance analyze on that and different destiny developments should be informative. As for a catchy intro... it really is somewhat problematical no longer understanding your target market and what ought to drawn them in. yet i imagine each and every human being is fascinated contained in the large image first, so perchance electricity use by using u . s . a . , then ruin that down into kinds of electricity use by using residing house equipment, and then on to gentle bulbs. and perchance then pass into capacity mark downs if each and every human being in that u . s . a . switched, and what number have switched1. do led lights have that blue glow?Take the bulb you have to the hardware store with you and get them to match it2. I know this is crazy but there is a static noise from my PC speakers when the switch to on the light in my room is flipped??? Like WTF!?If you have a compact fluorescent light bulb then these have some electronics in them that can cause interference. This may also be the case with LED lights although I do not have any experience with these. You might want to try changing your light bulb with one from another room and see what happens.3. What power source should i use to wire 250 led lights?So you will have 250 branches, each branch having a current limiting resistor and the led. There will be 20 ma per branch, so 5 amps total current. In each branch, the led will have 3.3v across it (that's higher than I would have expected, but if that's what the data sheet says ...), so if each branch has 5v across it, the resistor needs to drop 1.7v. With 20 ma thru the branch, the resistor needs to be R = E/I = 1.7v / .02 amps So R = 85 Ohms. Some chargers are more intelligent than just acting as a voltage source capable of a certain current. Many provide optimum charging characteristics for the battery it's made for. If you could experiment putting a few resistors across your BlackBerry phone charger and verify that the current follows Ohm's Law for a 5v source, then go for it.4. do infrared led lights reverse the signs of aging?Would'nt think so.Cosmetic companies market all sort of creams and lotions for this purpose.Make up is still the best camouflage5. want to install new led lights but they have aluminum wires , can i join to copper wiring with merrits?Although I doubt you have aluminum wiring in a new device (probably tinned copper). You can join aluminum wire to copper wire with alumiconns. These are special wire nuts that have a special jell inside and these are 1 use only (alumiconns are usually purple or the 2 brands I have used are purple) for example the box I have on the shelf is ideal brand Twister AL/CU, these are listed for aluminum to copper wire connections. Regular wire nuts create a fire hazard with copper to aluminum connections so it can or needs to be done with alumiconns. I would bet you have tinned stranded wire coming from the new fixture. If you take a knife and scrape the wires there will s probably copper under the tin. If copper under the tin you can just use a standard wire it that is the correct size for the wire.6. How quickly does a Crown Victoria Police Interceptor get from 0-60?Not fast enough, lol. The Crown Vic was the work horse of police agencies across the country and in many others for a long time not so much for its powerful acceleration rate (sarcasm) but rather because it had the right mix of useful attributes. It had a large body, good trunk space, could fit two semi average size officers in the front seat with gear (it could get tight), the V8 engine was big and powerful enough for high speeds and it was durable. Of course this was off the assembly line. In the old days prior to LED lights an extra battery and heavy duty alternator needed to be installed, those along with all manner of other gear (trunk safe, VHS tape deck in the old days), stop sticks, emergency kits and a mess of other stuff) weighed down the car substantially. It was funny to get a new car, take it to the shop that installed all this gear and watch it sink lower as it went in. Additionally, prior to the new LED light bars, the big old light bars created massive drag at high speeds and when they were switched on I swear you could feel car engine work harder while the car actually slowed down lol!Now with the new LEDs and other lighter equipment the load has lessened substantially. Of course the Crown Vic isn't made anymore and the current police fleet of them is dwindling. Many departments are switching to the Taurus and Explorer police cars and they do very well.How quickly does a Crown Victoria Police Interceptor get from 0-60?.
What Are Some Cool Things to Use LED Lights For?
Light where you need it, like under cabinets, in closets, and more1. Why wonu2019t any of my LED lights work, even when powered on with new batteries in them?Ulike incadescent lamp LED need some minimum voltage to work.If you ask about LEDs in seria, you need to found where is circuit open, it can be wire or single LED2. Convert my solar charged LED lights to AC?drgforconvertsolarlighttoAC3. Whats wrong with the LED lights i wired in my truck?i assume you have been on the battery end of that fuse or it could have blown. (So up would be ON) top after the battery use an inline 5 amp fuse. The beneficial passes by using the change. The neg is going basically to the neg of the lights furniture4. Is it wise to run 4 led lights at 20mA each to a 9 volt battery without a resistor.I know you can but should u?LED's are current operated devices. In your case you are depending on the internal resistance of the battery to limit the current. This resistance is not a reliable limit since it depends on temperature, condition of the battery and load. This would be considered a very poor design. Here is an idea. Measure the current and include a resistor to achieve the rated current5. Can led lights in video game controllers harm your eyes?No. LED lights do not emit UV rays, which is what WILL damage your eyes. UV light is emitted by the sun and tanning beds. It may cause some eye strain if you are staring at these LED lights in the dark for extensive periods of time, but it will not harm your eyes.6. How to wire LED lights to my subwoofer box?Led Subwoofer Box7. How do you turn off those LED lights on an Alienware computer?Try tracing the wires from the lights and see where they lead.

My 50" Plasma Model number DP50747 Will not come on. No LED lights no nothing. I was watching it and then bam?More than likely it is the power board circuit that is broken on the tv. You can email or call the manufacturer for a cost estimate, if you have no factory warranty left. More than likely it will not be cost effective in repair the tv than just buying a new one. This is a common issue on bargain price tvs. Panasonic makes the most reliable tv in the market today. Hope this will help you out10. why are my speakers not working?Check the monitor's OSD (on screen display, the menu for monitor settings). The computer does not need to be on for this. The monitor does need to be on. There are buttons precariously placed on the monitor. Push them to find the OSD. Push them to navigate through the OSD. Once in the OSD look for a place to enable the speakers. Look for a place to turn up the volume to the speakers. Look for a place to reset the OSD values back to there factory defaults. Some monitor buttons use LED lights on the monitor itself as a way to configure the monitor's settings. Its possible the audio cable from the computer to the monitor is broken. Its possible the computer is not configured to use it's sound card. OR The sound card could be broken. Test with a pair of headphones to see if the sound card outputs sound.11. Is it legal to have blue led lights on the bottom of a motorcycle?Where i live it is illegal to have blue lights period.the reasoning being that it is an official use light only,they dont want you looking like a cop,as if anyone could ever confuse the two.... I had blue lights on my bike,HAD being the key word.I was politely told at a gas station that it was a no no and to get it home asap. I see that on Harley's more and more though,it seems that is allowed or they are granted a bit more lee-way(sp) than the sport bike community.it could be just the area i live in. blues and reds and frowned upon.

What led up to it?When I was 17 years old I gave them my fingerprints. I figured if I was not doing anything wrong and I ever got in trouble it might help. I was not thinking clearly, and not just because of who my dad was. A few years later I wound up in Mental Health for not thinking clearly. It took me many many years to recover. Would I give my fingerprints to the FBI now? Probably not, or if I did I would realize it could do me just as much harm. That's not to say I would not do the same if I was 17 years old though. The problem was not that I gave the FBI my fingerprints. No the problem was that I was not using good senseHas the reduction in children's play time outside led to an increase in mental health issues?This is not something I specialize in however it is proven that kids are spending less time outside, making less childhood decions for themselves and metal health problem is on the rise. Now that's not saying WHY this is happening .. for instance if a child is overloaded with school work it could very easy be the simply do not have time for anything other than homework. . is it because of video games? Or something else.. everyone even professional has thier own oppion and facts are pointing to all kinds of reasons why children just are not out playing.. not to mention society has changed from the days kids were out playing all the time.How do I get over a guy friend who led me on?You both lead each other on.One of the things for low self image is a person waits for someone else to do something and not be direct. They always waiting for someone else to say and do. They wait and wait and wait when they too have a choice to be direct. Then when nothing happens they behave as victims, blaming someone else on how the person used them and how they were lead on.You lead him on as well.You weren't honest either.You weren't direct and so that's why time went by and let someone else, your head up. If you don't have boundaries and if you wait for things to happen then you waste time. If you be direct then you polarise the person to quickly show their intent and if it's not good enough....you immediately walk away.So you are also responsible for showing vulnerability and being direct.You weren't because you fear rejection and so, embrace the part that he didn't lead you on. You liked the attention. You craved for it. But you feared losing it too and that is why you weren't direct with him for you to be lead on.Both of you then lead each other on.Both used each other for some craving and emotional stimulationWiring led's to xbox 360 help?dont worry about watts, those will never exceed the voltage from your xbox seeing it gets electricity from your outlet, which is attached to a grid. your safe. get a sautering iron or pen i prefer pen, and place the led on the silver metallic square, sauter until the metal is liquid and place led on. it will take 2 seconds to turn solid and there you go.Have you ever led a double life? If so when and how?I did back in the day. I spent some very interesting time working with the Air Force office of special investigations. This is actually the first time I have ever brought this up in public. I wo not go into it other than to say it is very weird to purposefully misrepresent yourself to others.
The Impact of LED Lights on the Economy
The performance of LED bulbs is amazing, using 85% of the energy to produce the same amount of light as old incandescent lamps. The brightness of a 60-watt incandescent bulb can be achieved with a 10 watt LED bulb, and the heat is much lower than that of an incandescent lamp. LED lamps have a long life, many times longer than incandescent lamps, and are easy to maintain and environmentally friendly.Lighting accounts for about 15% of global electricity consumption, and billions of outlets around the world still contain incandescent bulbs. One of the best investments that developing and emerging economies can make is shifting from inefficient incandescent bulbs to ultra-efficient LED bulbs that haven't changed much in the past 125 years. Unlike Europe and the United States, these energy-consuming light bulbs will be phased out.According to estimates by the United Nations Environment Ministry, developing countries and emerging economies can save $40 billion in electricity and prevent 320 million metric tons of carbon pollution annually by transitioning to LED lighting. A spokesperson for the side event at the International Climate Change Conference announced new regulations aimed at phasing out inefficient incandescent bulbs and determining the minimum performance requirements for LED bulbs to replace them.The world's energy is declining, environmental protection and energy conservation is a matter that every country must pay attention to, and lighting is undoubtedly very large in terms of energy consumption. If this can be done well, the world's energy consumption will be greatly reduced.Original text from: Lampshining·RELATED QUESTIONWhy do my LED bulbs make a clicking noise whenever I turn them on?Hi!...
