AI Technical Summary

Technical Problem

Existing eye-protection lamps are inconvenient to adjust in height and are also inconvenient to repair.

Method used

An eye-protection lamp was designed, which uses a combination of a fixed plate, an adjustment mechanism, a fixed shell, a lighting fixture, and a positioning mechanism. The adjustment mechanism can adjust the height of the lighting fixture, and the positioning mechanism facilitates the separation and assembly of the lighting fixture from the fixed shell, enabling convenient height adjustment and maintenance.

Benefits of technology

The height of the eye-protection lamp is adjustable, making it easy to achieve the best lighting effect according to the usage situation, and also making it easy to inspect and replace the lighting fixture.
