Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to a vehicle lighting system that prevents fogging. Background Technology

[0002] Car headlights, as an important visual component of automobiles, not only ensure driver safety at night or in adverse weather conditions, but also serve as a unique way to showcase personality and taste. Consumers are paying increasing attention to headlight configurations when purchasing cars, from traditional halogen headlights to advanced argon headlights, and then to emerging LED and laser headlights. LED car lights refer to headlights that use LED technology for both internal and external lighting. External lighting equipment involves thermal limits and EMC issues, while LED car lights can be widely used to create the in-car environment. They have a lifespan of 50,000 hours, and the robust structure of LEDs makes them less susceptible to vibration, with no significant decrease in light output brightness during use.

[0003] For example, the vehicle light with anti-fogging function disclosed in the authorization announcement number CN215174770U includes a vehicle light base and a lamp cover. A hollow sealed cavity is formed between the vehicle light base and the lamp cover, and a lamp is installed in the sealed cavity. The vehicle light base has a vent hole, a vent nozzle is provided on the vent hole, and an air bag that communicates with the vent hole and can change its own volume is sleeved on the vent nozzle.

[0004] While it achieves the advantage of significantly reducing the cost of headlight defogging, it does not solve the problems of existing headlights being inconvenient to adjust the beam angle at multiple angles, lacking good ventilation and heat dissipation, and being difficult to heat the headlights to prevent fogging and to focus the light in multiple stages. This greatly affects the brightness of the headlights and the convenience of disassembly and maintenance in the future. Utility Model Content
