Description

technical field

[0001] The invention relates to the technical field of automobile auxiliary lighting, in particular to a manufacturing method of a quantum dot LED atmosphere lamp and a safety driving auxiliary lighting system. Background technique

[0002] Existing car atmosphere lights are mainly composed of multi-color luminous LED light strips, which are installed on the dashboard, center console, doors and seats of the car, which can realize the transformation of the lighting environment in the car. The main selling point is the high color gamut ( The luminous color is rich) and a variety of changes (breathing, flowing water, flashing, gradient, etc.), often through the center console or steering wheel buttons to adjust the color, brightness, lighting method.

[0003] The main defect of the current technology is that as an ornament, its practicality and intelligence are not strong, and it cannot realize intelligent adjustment according to the psychological state of peopl...
