Embodiment Construction

[0043] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0044] This embodiment provides a sunlight protection structure for vehicle lights, including a sensing module, which can acquire ambient light parameters;

[0045] The control module can determine whether the ambient light parameter obtained by the sensing module is greater than the preset threshold, and if so, determine that it is currently in a direct sunlight environment, and send a control signal to the actuator;

[0046] The actuator can change the position of the shading frame through the transmission shaft according to the control signal sent by the control module, so as to reduce the sunlight entering the optical module.

[0047] Such as Figure 1-12 As shown, the present embodi...

Abstract

The invention provides a sunshine protection structure for a vehicle lamp. The structure comprises a sensing module, a control module and an executing mechanism, and can adjust the position of a shading decorative frame according to a control signal sent by the control module and change the amount of sunshine entering an optical module. The position of the shading decorative frame is adjusted through the executing mechanism, so that sunlight is shaded, the problems of material overheating and function damage caused by sunlight focusing are solved, and influences on other modeling parts in thelamp are avoided.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to a sun protection structure for automobile lamps. Background technique [0002] With the development of the automobile industry and the continuous improvement of automobile styling design, more and more optical modules with lenses are used in automobile lights. Sunlight shining on the lens may focus on the inner parts of the lamp after refraction and reflection, causing the local temperature of the parts to rise beyond the tolerance limit of the material, resulting in appearance or functional damage. Existing car lights usually use partial aluminum plating, replace high-temperature resistant materials or add metal heat shields to protect the damage caused by sunlight focusing through the lens, which has a great impact on the shape of the car lights and will also occupy the internal space of many car lights . In view of the above-mentioned problems, designing a new car lamp sun...
