Description

Underwater laser lighting lamp

Technical Field

The invention relates to the technical field of deep sea active illumination imaging, in particular to an underwater laser illuminating lamp.

Background

In many fields where targeted light sources are necessary, such as deep sea imaging, automotive lighting and other industrial fields, special light sources are urgently required for illumination. The obtained image has the problems of color distortion, image blurring and the like due to the fact that ordinary light is absorbed and refracted by the water body when being transmitted in the water body, and a large amount of biological and mineral resources are stored under the ocean, so that the method has great development value;

it is necessary to obtain a clear image of the sea bottom to judge the information of the sea bottom. Most of the existing deep sea illumination light sources are mainly LEDs, but the brightness of the existing deep sea illumination light sources is low, the illumination with high brightness needs to drive a plurality of LEDs simultaneously, the volume of a light source module is increased, and the volume of a sealed cabin is increased in deep sea detection, so that the use is not facilitated.
