[0002] Car lamps can provide a good external lighting environment for cars when the light is poor, which plays a very critical role in safe driving. Therefore, the safety, service life and lighting characteristics of car lamps are all key links. The light source of traditional car lamps is mostly halogen bulbs. Halogen bulbs, also known as tungsten halogen bulbs and quartz bulbs, are a variant of incandescent lamps. The lighting characteristics are average, and the lifespan is not long enough. With the good lighting characteristics, long service life and low energy consumption of LED lamps, more and more car lamps are equipped with LED lamps.
