Description

Technical Field

[0001] This invention belongs to the field of automotive lighting technology, and in particular relates to a fog-proof automotive light with a retractable and breathable structure and a retractable control system for the breathable structure. Background Technology

[0002] Headlight fogging refers to the formation of a thin layer of fog on the inner surface of the headlight lens. Headlight fogging reduces the brightness and effective projection distance of the light, decreasing the visibility of the vehicle's position and direction of travel to other vehicles and pedestrians.

[0003] One current method for preventing fogging in vehicle lights is to deploy a venting structure inside the light. This structure increases airflow within the light, thus reducing fogging. However, different areas inside the light have varying airflow requirements. A venting structure with fixed openings cannot effectively cover all areas of the light, resulting in significant temperature differences inside the light and affecting the anti-fogging effect.

[0004] To address the issue that fixed-aperture ventilation structures cannot effectively cover all areas inside the lamp, thus affecting the anti-fog effect, a fog-proof vehicle lamp with a retractable ventilation structure and a retractable ventilation structure control system are proposed.
