Description

Technical Field

[0002] Laser lights have the advantages of bright colors, high brightness, good directivity, long range, and easy control, making them look more magical and dreamy. They are used in buildings, parks, squares, theaters, etc., and can attract the attention of people from as far as several kilometers away by utilizing the non-divergence of laser beams. They can emit light of different colors according to different needs. Existing laser lamps usually have complex structures, and are equipped with optical lens components with single-effect color patches. They are not easy to disassemble and replace, and cannot meet some scene-based and personalized needs. Therefore, when used in different scenes, laser lights with different lighting effects are required, resulting in high cost investment. In addition, there are more and more application scenarios for laser lighting, and it is inevitable that some scenes will be used outdoors or in rain and snow. If dust enters the laser light, it will stick to the laser output mirror and affect the quality of the light spot. Water droplets splashing into the laser may damage the circuit board.
