AI Technical Summary

Technical Problem

Existing automotive interior ambient lighting has a complex structure, and its dynamic water ripple effect is highly repetitive, making it difficult to simulate real water ripple changes and consuming a lot of energy.

Method used

The design employs a light-transmitting component and a light source component, utilizing the sloshing of liquid within the containment cavity to create a dynamic water ripple effect. Light passes through the liquid to form random lighting. The structure is simple and requires no driving or control. It combines multi-color LED light sources and a light guide plate to optimize light efficiency.

Benefits of technology

It achieves a dynamic and realistic water ripple effect, with highly random lighting effects. Its simple structure makes it easy to manufacture and install, requires no additional energy consumption, and also has a humidification function, thus enhancing the applicability and functionality of the ambient lighting.

Abstract

The atmosphere lamp comprises a fixing base, a light transmitting assembly and a light source assembly, and the light transmitting assembly is arranged on the fixing base; the light-transmitting assembly comprises a first light-transmitting wall and a second light-transmitting wall, and the first light-transmitting wall and the second light-transmitting wall are oppositely arranged in the first direction. A closed containing cavity is formed in the light-transmitting assembly, liquid is contained in the containing cavity, and the volume of the liquid is smaller than the volume of the containing cavity. The light source assembly is arranged on the fixed seat, and the light source assembly and the first light-transmitting wall are oppositely arranged in the first direction; the light source assembly is suitable for emitting light to the light-transmitting assembly, and the light is suitable for penetrating through the light-transmitting assembly and being projected outwards through the second light-transmitting wall. The lighting effect of the atmosphere lamp can simulate the dynamic real water ripple effect, the lighting effect has randomness, and the atmosphere lamp is simple in structure and easy to produce and install.
