LED lighting up lamp market prospects

LED (light emitting diode) is a rapid rise in recent years as a low-field-type electroluminescent semiconductor light-emitting device, a way to convert electrical energy into visible light semiconductor breakthrough incandescent tungsten light with energy-saving lamps three-color dye luminous the principle of the use of electric light emission. LED spectrum almost entirely concentrated in the visible light spectrum, the luminous efficiency of up to 80% -90%. Because of the long life, high luminous efficiency, low energy consumption, no radiation, no pollution characteristics, LED high bay light has been widely used in the field of lighting. Today, the high-power LED has been used extensively for automobile master brake lights, tail lights, turn signals, lights, instrumentation and interior lighting can also be used. In automotive lighting, it is estimated that by 2010, LED will occupy most of the taillights lighting (including down lights and license plate light). The all-LED design rear lights (taillights, brake lights and turn signals) has appeared in the 2000 model Cadillac and S-Class Benz, and other high-end car, LED can be car objects provide independent local lighting such as dome light, reading lights, grab handle, lock, switch, cup holder, seat belt buckle, mirrors, borders, etc., the increasingly widespread use. Lights (incandescent), compared with the traditional car, LED energy saving, long life, maintenance-free, explosion-proof, easy to control, and environmental advantages, plus LED luminescent own unique characteristics, so that the lamp shape does not deformed because of prolonged heat, thereby increasing the life of the entire unit. LED inherently has the advantages of small size, reduced the volume of the entire group of lamps, when applied to the front lights further so that the valuable space of the engine and other related equipment space. Existing halogen bulb design discharge lamps, and lights a total length of 300mm, and in many of the design of the concept car, LED highbay light only 125mm long. The advantages of small size, so that the headlight design is more flexible, and thus create a different body shape visual perception, broke the traditional circular design of the lights. In addition, due to the light-emitting speed faster than light bulbs, to quickly convey to the back of the vehicle brake information, help to improve traffic safety. Therefore, LED automotive lighting systems the revolutionary development opportunity. Currently widely used LED color blue, red and green, and white LED for car headlights just started. As technology improved, the brightness has been gradually increasing automobile headlamp white LED has a very good future. LED as a new light source alternative to the traditional incandescent light source is technically ripe. LED product market from the current point of view, however, the high cost of high brightness LED automotive lighting brightness requires a large number of LED demand will undoubtedly increase the cost of the light source. The application is only a small amount of imported luxury cars in the domestic car industry. However, with the development of LED products, industrial capacity increase of high-brightness LED, LED products prices there is a lot of decline in its good performance makes the LED light source will become the mainstream in automotive lighting products.
