LED Application in Automotive Fog Light System Advantages

Bright LED fog lights

With the rapid development of automotive lighting technology, rapid development of the automotive industry and fierce competition in the market, modern automotive lighting systems have become increasingly demanding for luminous efficiency, safety performance, and aesthetics. The design and processing of free-form surface mirrors and LED lighting systems in automotive lighting are crucial

The design of non-imaging optics for automotive lighting systems is a multidisciplinary, complex process. Compared with the combination of a conventional parabolic reflector and an optical lens, the combination of a free-form surface and a Fresnel lens can simultaneously achieve the convergence and light distribution functions. In this way, the rear fog lamp can not only save space but also reduce installation costs. The design of the freeform surface makes the rear fog lamp more flexible and compact.

LED is a new generation of competitive new solid light source, with high efficiency, pure light color, low energy consumption, long life, reliable and durable, non-polluting, flexible control, fast response, small size, impact resistance and so on. Since the light output by the LED chip conforms to the Lambertian distribution, the direct application to an actual automotive lighting system without proper light distribution processing will not be able to meet the required standards. Therefore, the secondary optical design of the lighting system with LED as the light source is required, and the design result directly affects the luminous efficiency, energy consumption, and the safety performance of the lighting system.

Currently, LEDs have been used in automotive signal systems such as brake lights, parking lights, turn signals, and reversing lights. At present, an important reason why LED headlights have not yet been applied on a large scale is heat dissipation, and the LED front fog lights of cars need less energy than headlights, and the number of LEDs used is also relatively small, and with the single single LED light continuously improve efficiency and reduce waste heat generated by the LED headlamp constraint automobile technical bottlenecks can be easily solved in the automotive LED fog lights, rear fog lamp LED of automobile and therefore has great value.

China's LED industry started in the 1970s. After more than 30 years of development, China's LED industry has initially formed a relatively complete industrial chain including the production of LED epitaxial wafers, LED chip preparation, LED chip packaging, and LED product applications. Many: NVC lighting, rectangular lighting, Warwick Cade. Under the promotion of “National Semiconductor Lighting Project”, the semiconductor lighting project industrialization bases of seven countries including Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang were formed. The Yangtze River Delta, the Pearl River Delta, the Chongqing Triangle, and the northern region have become the gathering grounds for the development of China's LED industry.
