LED light sourceas a new light source, the initial use was in 1962. In market demand and technological progress, driven, LED light source has undergone a glorious history, from the first LED light sourceonly as directed, to the present LED light source can be produced with large outdoor display; LED light source from the early 650nm red LED light source, and now appear white LED light source; LED light source from the original only a few thousandths of lumens, the efficiency of light-emitting only 0.1lm / W, to the current luminous efficiency white LED light source can be more than 40lm / W.
LED light source, especially in the past decade, LED light source to improve the quality of a 10-fold, while manufacturing costs have dropped to the early products of 1 / 10. This trend is also further developing, which makes LED light source for information emerging optoelectronics industry's most influential new products, at the same time as the technology to further improve, LED light source must also use the prospect of a broader.
But the current technology and the use of view, LED light source is far from playing its proper potential. LED light source advantages:
LED light source 1, the high-energy: saving energy is environmentally clean. DC-driven, ultra-low power (single tube 0.03-0.06 watts) electro-optical power conversion close to 100%, the same lighting effects than the traditional energy source more than 80%.
LED light source 2, long life: LED light source which some people refer to long life lamps, which means the lights never go out. Solid cold light source, epoxy package, lights and no loose body parts, there is no filament light-emitting burnability, thermal deposition, light failure, such as the shortcomings of life up to 60000-100000 hours, longer life expectancy than traditional light sources 10 more than tripled.
LED light source 3, and more changes: LED light sourcecan make use of red, green, blue trichromatic theory, under the control of the computer technology to make three colors with 256 gray-scale and indiscriminate mixing, can produce 256 × 256 × 256 = 16777216 colors to form a different color combination is very dynamic and the achievement of a variety of dynamic change effects and a variety of images.
LED light source 4, benefit environmental protection: environmental benefits are better and there is no ultraviolet spectroscopy and infrared neither heat nor radiation, glare small and recyclable waste, there is no element of mercury pollution are not the cold light source, it is safe to touch, typical of the green lighting.
LED light source 5, high-tech tip: with traditional light sources, compared monotonous glow, LED light sourceis a low-pressure micro-electronics products, the successful integration of computer technology, network communication technology, image processing technology, embedded control technology and thus the number of information technology Semiconductor optoelectronic devices is "high-tech tip" technology with online programming, unlimited upgrades, the characteristics of flexible
