Currently, applications of LED lighting in the automotive sector have extended from the interior lighting to the outside. The application of full color in the automotive interior lighting is already very mature, for example dashboard backlighting switches, car reading lamp or head-up display system and so on. Insiders said that, in addition to the current common applications of taillights, high-mount stop lights, turn lights and reversing lights will also adopt LED in large-scale in the future. According to the report issued by relevant department in 2013, it is estimated that about 95 % of new cars worldwide will using one or more LED taillights.
In addition, the automotive LED decorative lightings are very hot at home and abroad, which is a new type of car decoration products and combines safety, practicality and decorative in a whole. Because LED chassis lamps have good ability of water resistance and impact resistance, it usually requires neither maintenance nor scrubbing. But the power is equivalent to the headlight of a car. It does not bring excessive burden to the car battery and engine in use. The product is installed at the bottom of the car (or car interior). At night or in foggy day, rainy day or road with poor visibility, it can provide a good driving or parking location identifier of your car for pedestrians or other vehicles to reduce accidents. When the LED lights turn on at night, at the bottom of the car (or car interior), it presented red, blue, green and other multiple colors, which very beautiful and greatly adored by young car family of all ages.
With energy-saving, environmental protection, long lifespan, anti-vibration, small in size and quick in response, the process of automotive LED lamps is gradually opened up. On the technical front, LED auto lamp lighting has higher requirements than normal lighting, which must meet the needs of high light output and maintain the junction temperature ≤ 120 ℃. In such case, LED lamps used in automotive lighting systems will have higher cost and it will have a large difference in price with the traditional lighting, such as a high-end car, the price of the incandescent lamps combination is 120 yuan / sets, but LED combination lamps will be 210 yuan / sets. High cost restricts the commercialization of LED auto lamps. Facing of the enormous potential of LED in the automotive lighting area, I believe that reducing the cost led lighting under the premise of protecting the quality of the product will be focus point of LED auto lamps in the future development.
