The four core dimensions of automotive lighting include light source technology, functional classification, technical implementation solutions, and intelligent interaction functions. Light source technology has evolved from halogen lamps and xenon lamps to LED. Currently, LED has become the mainstream due to its low energy consumption and long lifespan, while laser headlights are limited to high-end models due to high costs. For functions, they are divided into lighting lamps (such as headlights and fog lights) and signal lamps (such as turn signals and brake lights). Among them, headlights integrate multiple functions like low beam and high beam, and taillights tend to adopt a through-type design to enhance recognition. Technical implementation solutions cover LED matrix, DLP projection, etc. Intelligent interaction is a trend in recent years. For instance, the Adaptive Driving Beam (ADB) system can automatically adjust the light beam to avoid glare, and projection technology can display warning information on the road. These dimensions together promote the development of automotive lighting from basic lighting to safety, personalization, and intelligence. For example, some models have implemented functions such as curve fill light or pedestrian warning projection.
