LED lighting market prospects

LED (light emitting diode) is a rapid rise in recent years a low field type electroluminescent semiconductor light emitting device is capable of converting electrical energy into visible light of the semiconductor, it breaks through the principle of incandescent tungsten filament and energy-saving lamps three color luminous powder, and the use of electric light. The spectrum of LED is almost all concentrated in the visible band, the luminous efficiency can reach 80%-90%. Because of its long life, high light efficiency, low energy consumption, no radiation, no pollution, LED has been widely used in the field of lighting.

Today, high-power LED has been widely used in the car's main brake lights, taillights, direction lights, indicators, can also be used for instrumentation and interior lighting. In automotive lighting, it is estimated that by 2010, LED will occupy most of the car taillight lighting (including reversing lights and license plate lights). The design of LED (rear taillights, brake lights and turn signals) have appeared in 2000 Cadillac and S class Benz and other luxury cars, in addition, local lighting LED can also provide independence for the object in the car, such as lamp, reading lamp, grab handle, lock, switch, cup holder, Anne the hasp, mirror frame, widely.

With the traditional car lights (incandescent lamp) and compared, LED has the advantages of energy saving, long service life, maintenance free, explosion-proof, easy control and environmental advantages, with its unique luminescence characteristics of LED, makes the lamps shape not because of long-term heat deformation, so as to improve the whole life of the lamp. LED has the advantages of small size, when applied to the front lights can reduce the size of the entire set of lamps, and further give up valuable engine space and other related equipment space. Most of the existing halogen bulbs are designed by the discharge lamp, and the total length of the lamp is about 300mm, while in the design of many concept cars, the LED lamp is only 125mm long. The advantages of small size make the lamp design more flexible, and create different visual perception for the car body modeling. In addition, due to the speed of light faster than the bulb, so that the vehicle can quickly convey the brake information, help to improve traffic safety. Therefore, LED lighting system to the car has brought revolutionary opportunities for development. Widely used LED the main color is blue, red and green, white LED for automobile lamp has just started. With the improvement of technology, the brightness has gradually increased, so the application of white light LED in the automotive headlamp has a very good prospect. LED as a new source to replace the traditional light source in the technology has matured. However, from the current LED product market, the higher the cost of high brightness LED, the brightness of the automotive light source requirements for the number of LED demand will undoubtedly increase the cost of vehicle light source. Now only in a small number of imported luxury cars have been applied in the domestic car industry is still very little. However, with the development of LED product itself, with the increase of industrial high brightness LED capacity, LED product prices will be greatly decreased, the good performance of the LED light source will become mainstream products in the automotive light.
