Alight is specialize in product and develop LED series source, LED source from common brightness, high brightness, ultra brightness to high power LED( LED die series, 1W 、 2W 、 3W 、 5W 、 10W ), rely on advanced technology, since 2002, we commit ourselves to develop LED illumination instead of traditional halogen and incandescence illumination. Our LED lighting source are including MR11 、 MR16 、 GU10 、 E27 、 PAR20 、 PAR38, power range from 1W to 500W, all of our product could be applied to various illumination, our products currently are hot sales in Europe and USA against its excellent quality and competitive prices. In the future, we would continue to take effect to product and develop LED lighting source, strive to offer the most excellent and reasonable price to illumination user in all over the world.
LED lighting is also called photon fusion and solid state lighting ( SSL).
LED's are light emitting diodes - in laymans terms they're like electrical one-way only valves that glow instead of getting hot when a lot of pressure is put through them.
They simply put out light (glowing photons) instead of heat like a normal diode on a PCB board.
These diodes are also then sealed in resin to make them shockproof and waterproof.
This is very different to the traditional filament bulbs that rely on a very thin piece of wire strung between two poles that burn very brightly when a current is passed through it.
The wire burns continuously whilst giving off quite a deal of wasted heat.
Glass filament bulbs are thin and also fragile which keeps an industry alive replacing light bulbs.
Advances from VHS to DVD get a lot more attention these days than cheaper, better lighting although the outdoor enthusiasts have recognize the incredible potential of LED lighting particularly in the form of headlamps and torches.
The difference at night time is incredible -you will see colors truly represented as they are seen during daytime - spiders and other insects eyes glowing back at you !
How long do LED's generally last?
The industry standard for LED is around 50000hrs. As all things do they will degrade iniitially up to 10% over the first 1000hrs of operation followed by a slower rate of decline to 30% loss after 50000hrs. Commercially available LED's are generally blue LED's with a fluorescence applied to them and its the fluorescence that degrades not the chip/diode itself. It also depends if the LED's are being "driven" hard or voltage is variable.
The types of commercial dome-typeLED's available these days are called "static sensitive" and can be badly affected by variations in voltage and current - that's why they're OK on batteries (if not run too low) but sensitive to other forms of power like 240vAC/12vAC transformers.
Will flat batteries affect them?
Over time - yes - low voltage is a universal problem with electrical componetry.
We're actually intruding multi-volatge units as time goes on.
From customer feedback and our own testing we've found that low voltage is the leading killer of most LED.
Heat is a byproduct of low voltage and will quickly cause failures in the PCB boards that the LED's are mounted on.
Our new 8-30vDC units are an exception in that they will operate down to 8vDC.
