Overview
Abbreviation word in English, the main implication: LED = Light Emitting Diode, light-emitting diode, is a way to visible light energy into solid-state semiconductor devices, which can directly electricity into light; LED = Large Electronic Display, a large electronic display ; LED = Lupus erythematosus disseminatus, disseminated lupus erythematosus, a chronic, idiopathic autoimmune disease; led is the past tense and past participle of lead, which means "leader, to lead"; Russia's Pulkovo airport, IATA code. This term describes light-emitting diodes.
LED Advantages
Determine the intrinsic characteristics of LED is ideal light source to replace the traditional light sources, it has a wide range of uses.
A small volume
LED is basically a very small chips are encapsulated in epoxy resin inside, so it is very small, very light.
Second, low power consumption
LED power consumption is very low, in general, LED's operating voltage is 2-3.6V. Operating current is 0.02-0.03A. That is to say: it does not exceed power consumption of 0.1W.
Third, long life
At the right current and voltage, LED life of up to 10 million hours.
Fourth, high brightness, low heat
Fifth, environmental protection
LED is made by a non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, while LED can also be recycled.
VI, durable
LED is completely encapsulated in epoxy resin inside it than light bulbs and fluorescent tubes are strong. Light and no loose parts of the body, these features make the LED can be said is not easy to damage.
High energy: saving energy is the environmental pollution. DC drive, ultra-low power consumption (single tube 0.03-0.06 W) electro-optical power conversion close to 100%, the same lighting effects than traditional energy sources more than 80%.
Long life: LED light source that some people call long life lamps, which means the light never goes out. Solid cold light source, epoxy resin, light and no loose parts of the body, there is no filament light easy to burn, thermal deposition, light failure and other shortcomings, the service life of up to 60,000 to 100,000 hours, longer life than conventional light sources 10 times above.
Many changes: LED light source can make use of red, green and blue color theory, under the control of the computer technology to three colors with 256 levels of gray, and any mix, you can generate 256 × 256 × 256 = 16777216 colors, the formation of different light combination of changing color to achieve a variety of effects and a variety of dynamic images.
Environmental benefits: better environmental benefits, there is no ultraviolet and infrared spectra, neither heat nor radiation, glare small and recyclable waste, no pollution, no mercury elements, cold light source, safe touch, typical of the green lighting.
High point: with the traditional light source compared to the monotonous glow, LED lighting is low voltage microelectronic products, the successful integration of computer technology, network communication technology, image processing, embedded control technology, it is also a digital information products, is Semiconductor optoelectronic devices "high point" technology, with online programming, unlimited upgrades, flexible features.
