AI Technical Summary
Existing automotive interior dome lights have limited functionality and cannot meet the lighting needs of the exterior of the vehicle. Furthermore, the magnetic connection is unstable or difficult to disassemble, making existing portable lighting devices inconvenient to use.
A detachable magnetic vehicle lighting assembly was designed, which adopts a base and lamp body structure. The base is fixed to the car roof by buckles and screws, and the lamp body is connected to the base by a mechanical detachable connection structure. It integrates control circuit and charging system. The lamp body is equipped with multi-color temperature LED and flashlight LED. Combined with the magnetic and hanging structure, it supports use inside and outside the vehicle.
It achieves perfect integration of interior and exterior lighting functions, requires no additional equipment, has reliable connection, is easy to operate, features multi-functional lighting and efficient heat dissipation, adapts to various exterior usage scenarios, and enhances the user experience.
