Problems solved by technology

However, in the car headlights using this working mode, once the structure of the reflective surface/condenser is determined, the light pattern of the car headlights is also determined, and it is impossible to change the light pattern according to the use environment. In addition, because the output light shape of the existing light source (bulb or LED) is fixed, the car headlights using the above working mode cannot change the distribution of the light on the ground in front of the car.
[0003] Existing DLP smart headlights need light sources for lighting. Conventionally, high-pressure mercury lamps or LED light sources are used, but both light sources have some shortcomings. High-pressure mercury lamps have short life, high heat generation, and

Description

technical field [0001] The invention relates to the field of automobile intelligent lighting systems, in particular to an automobile intelligent headlight laser light source system and an application method. Background technique [0002] At present, the mainstream technology of traditional car headlights is the working mode of light source (bulb or LED) plus reflective surface / condenser, that is, the light is reflected by the reflective surface / condenser to achieve the desired light pattern. The technology is mature and reliable. However, in the car headlights using this working mode, once the structure of the reflective surface / condenser is determined, the light pattern of the car headlights is also determined, and it is impossible to change the light pattern according to the use environment. In addition, because the output light shape of the existing light source (bulb or LED) is fixed, the car headlights using the above working mode cannot change the distribution of the ...
