Although the current LED headlamps have low penetration rate, they are highly profitable applications that LED manufacturers want to actively introduce. Due to the development of LEDs towards miniaturization, the design of the headlights is more flexible. From the past, the lighting function has been extended to intelligent matrix lighting, equipped with cameras and sensing systems to enhance driving safety and serve as a bridge between vehicles and vehicles. The electric vehicle has become the main light source for energy saving purposes. The above is the biggest difference between the LED light source and Halogen and HID (High Intensive Discharge) lamps. The research structure predicts that the penetration of LED headlights for vehicles in 2020 will grow to 2015. 3 times. Because of the high price, the LED headlights for vehicles have their first introduction market. In terms of automobile categories, electric vehicles and hybrid vehicles emphasize the characteristics of energy saving and environmental protection, just as LED light sources meet this demand. In 2020, such vehicles The proportion of the total market size will reach 7%. In addition, LED light source accounts for a relatively low proportion of high-priced car costs, and such models are designed with styling and smart lights, so the proportion of LED imports is higher than that of cheaper cars. When the LED components are moving toward miniaturization, the headlights not only provide lighting functions, but also become part of the "face" of the car, and even highlight individual performance, becoming one of the main considerations for consumers to purchase vehicles. In addition, with the rise of V2V (Vehicle to Vehicle) applications, LED headlights also emulate mobile communication software, add display emoji, driver health information, etc. to other drivers, become a simple communication tool between drivers, and increase driving Safety. Intelligent LED matrix headlights play a very important role in driving safety. The light source structure is to arrange multiple LED components into a matrix style, and is equipped with a camera module, a sensor and other systems. Each LED has a point and a function, and a matrix headlight will According to different road conditions, the light beam can be moved according to the surrounding environment or the turning section. When there are more LEDs, the more flexible the area should be irradiated or not, so as to increase driving safety. Under the above-mentioned additional functions and differentiation design, the LED light source for the headlights will gradually replace Halogen and HID. It is estimated that the LED proportion will exceed the HID lamp by 2020, which is 3 times higher than that of 2015, up to 15%. . In terms of research and development, the current direction of LED headlight research and development is mainly the use of fisheye plus LED light source module or LED bulb solution. The increase in the penetration rate of LED headlights in automobile brands has led lamp manufacturers to actively look for LED manufacturers capable of producing and designing LED lamps.
