Although the current penetration rate of automotive LED headlights is low, it is a high-profit application product that LED operators want to actively introduce. Due to the development of LED towards miniaturization, the design of headlights is more flexible, which emphasizes lighting function from the past, extended to intelligent matrix lighting, equipped with cameras and sensing systems to enhance traffic safety, as a communication bridge between vehicles, electric vehicles for energy-saving purposes and become the main light source, etc, the above is that LED light source is different from Halogen and HID ( High Intensive Discharge) At the big difference of lamps, the research structure estimates that the penetration rate of LED headlights for 2020 vehicles will grow to 3 times compared with 2015. Due to the high price of automotive LED headlights, there is a market for their first introduction. In terms of automobile category, electric vehicles and hybrid electric vehicles emphasize the characteristics of energy conservation and environmental protection, and the LED light source meets this demand, in 2020, the proportion of such cars in the total market size will reach 7. In addition, LED light sources account for a relatively low proportion of the cost of medium and high-priced cars, and such cars emphasize the design of modeling and intelligent lights, so the proportion of LED import is higher than that of affordable cars. As the LED components move towards miniaturization, the headlights not only provide lighting functions, but also have become the 'face' part of the car, and even highlight the personality performance, becoming one of the main considerations for consumers to purchase vehicles. In addition, with V2V ( Vehicle to Vehicle) With the rise of applications, LED headlights also follow the example of mobile phone communication software, increasing the display of emoticons, driver health messages, etc. to other drivers, becoming a simple communication tool for drivers, and increasing driving safety. The intelligent LED matrix headlamp plays a very important role in driving safety. The light source structure is to arrange multiple LED elements into a matrix pattern and carry systems such as camera modules and sensors, each LED has a point and off function, and the matrix headlights will adjust the light shape according to different road conditions, and the beam can move according to the surrounding environment or the turning section. When there are more LEDs, the more flexible the adjustment should be to illuminate or not to illuminate the area to increase driving safety. According to the design of the above-mentioned additional functions and differentiation, LED light sources for headlights will gradually replace Halogen and HID. It is estimated that the proportion of LED is expected to surpass HID lamps by 2020, which is 3 times higher than that of 2015, up to 15. In terms of research and development, the current research and development direction of LED headlights is mainly to adopt fisheye plus LED light source module or LED bulb scheme. The increasing penetration rate of LED headlamps in automobile brands has enabled lamp manufacturers to actively seek LED manufacturers with the ability to produce and design LED lamps for cooperative development.
