The advantages of LED light source

① new green light: LED light source to use cold, glare is small, no radiation, no use of harmful substances. LED is low voltage, DC drive, ultra-low power consumption (single tube 0.03 ~ 0.06W), electro-optical power conversion close to 100%, under the same lighting effects than traditional energy sources more than 80%. LED's environmental benefits of better, no ultraviolet and infrared spectra, and recyclable waste, no pollution, no mercury elements, safe touch, typical of the green lighting.
② Long life: LED cold light source for the solid, epoxy resin encapsulation, vibration, light body and no loose parts, there is no filament light easy to burn, heat deposition, the light fades and other shortcomings, the service life of up to 60,000 ~ 100,000 hours, is the traditional source of more than 10 times the life. LED performance is stable, can be -30 ~ +50 oC work environment.
③ multi-transform: LED light source can make use of red, green and blue color theory, computer technology under the control of the three colors with 256 levels of gray, and any mix, you can generate colors, the formation of different color combination. Color changing LED light combination can achieve a variety of dynamic effects and a variety of images.
④ High-tech: with traditional light sources glow comparison, LED light source is a low-voltage microelectronics products, the successful integration of computer technology, network communication technology, image processing and embedded control technology. LED lights use traditional chip size 0.25mmX0.25nm, and the size of LED light in general should be more than 1.0mmX1.0mm. Desktop work forming the LED die structure, inverted pyramid structure and flip chip design to improve the luminous efficiency, which issued more light. LED packaging design innovations, including high conductivity metal block base, bare flip-chip design and type casting plate lead frames, etc., these methods can be used to design high-power, low thermal resistance of the device, and these devices than traditional LED illumination greater illumination products.
Currently a typical high-flux LED devices can produce a few tens of lumens luminous flux lumen to update the design of a device can be integrated more of the LED, or installed in a single assembly in multiple devices, so that the number of lumens output equivalent to a small incandescent lamp. For example, a 12-chip high power LED devices can output 200lm monochromatic light energy, the power consumption between the 10 ~ 15W.
LED light source applications are very flexible and can be made into points, lines, various forms of short, light products; LED control is extremely convenient, as long as the adjustment of current, you can freely adjust the light; different combinations of color changing light, the use of timing control circuit and better meet a variety of dynamic effects. LED lighting has been widely used in various devices, such as battery-powered flash, voice-activated micro-lights, security lights, outdoor and indoor stair lighting roads and buildings and mark continuous lighting.
The emergence of white LED, the LED lighting function to the identity function from substantial step taken. White LED closest to the sun, more exposure to better reflect the true color of the object, so from a technical point of view, the white LED is undoubtedly the most cutting-edge LED technology. At present, the white LED has entered a number of application areas, emergency lights, flashlights, flash and other products have come out, but because the price is very expensive and therefore difficult to spread. White LED popular premise that lower prices, while prices fell in the white LED to be a certain size of the market after the possible integration of both technological progress ultimately depends.
