Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to an automotive ambient lighting system. Background Technology

[0002] There is a wide variety of stylish decorations for car interiors, and car design elements are becoming increasingly fashionable. Some car brands are equipped with ambient lighting from the moment they are produced. Ambient lighting is a type of lighting that serves a decorative purpose, mainly to make the car cabin more dazzling at night, enhance the atmosphere, and create an interior ambiance. Users can set different colors and brightness effects according to their personal preferences and needs, thereby achieving the purpose of decorating the car interior and enhancing the atmosphere.

[0003] For example, the published document CN 212132109U, published on 2020-12-11, entitled "Automotive Ambient Light, Automotive Ambient Light System and Automobile," discloses an automotive ambient light installed on the back of a translucent interior panel. The ambient light includes a mounting base and a light-emitting module mounted on the mounting base, with the light-emitting surface of the light-emitting module facing the interior panel. In practical use, the ambient light effect of the above-mentioned device is usually set to the system default, and the user cannot adjust the brightness. The ambient light modes are limited, resulting in poor practicality. Therefore, we propose an automotive ambient light system. Utility Model Content
