Car lamps are a key factor in the safe driving of cars. With the rapid development of the automotive industry and the maturity of LED lighting technology, LED lighting technology has been applied to interior lighting of automobiles, and has gradually been applied to exterior lighting of automobiles such as headlights, turn signals and rear lights. The development of LED lighting in the interior of the car has been very mature; in the exterior of the car LED lights have developed to include headlights, fog lights, tail lights, brake lights, turn signals, daytime running lights and other lighting. Compared with traditional lighting fixtures, LED lamps have been used as headlights by many mid-to-high-end cars because of their small size and easy change, enriching the appearance design of modern cars and improving the recognition of car brands. In the near future, with the continuous improvement of LED technology and the gradual maturity of the automotive lighting market, the development prospects of LED lighting technology in the field of automotive lighting will become better and better.

With the development of automotive LED lamps, with the development of automotive technology, automotive lamps have gradually developed from the most primitive incandescent lamps to halogen lamps, xenon lamps and LED lamps. In recent years, LED technology has played an increasingly important role in automotive lighting systems, from the initial automotive interior lighting such as instrument lights, backlight lighting, reading lights and other basic lighting applications, gradually developed to external lighting such as far and near lights, Daytime running lights, turn signals, high-mounted brake lights and combination tail lights, etc. Now car taillights have basically been used in all models, and the far and near lights are gradually becoming mature. Smart LED lights and laser lights will be the development trend of future automotive lighting. Although the LED light source is a very ideal light source, it will take a certain transition period to completely replace the traditional light source.

Because of the high production cost of LED light sources, the need to improve the technology and the imperfect regulations, it will take a certain amount of time for LEDs to be fully applied to automobile headlights, and it is not realistic to fully replace halogen lamps and xenon lamps at this stage. However, LED technology is constantly improving, and the cost of use is decreasing year by year, and it is only a matter of time before the extensive and comprehensive application in automotive lighting. Safety, environmental protection and intelligence are the development trends of LED lights, and they are maturing year by year. In the future, more advantageous lighting technologies such as laser lighting will appear to drive the continuous progress of automotive lighting technology.
