Lighting fixtures with light projection angle adjustment function

technical field

The invention relates to a lighting fixture, in particular to a lighting fixture with the function of adjusting the light projection angle.

Background technique

Regarding the comparison between light-emitting diodes (LEDs) and traditional light sources, light-emitting diodes have the advantages of small size, power saving, good luminous efficiency, long life, fast operation response speed, and no thermal radiation and mercury and other toxic substances.
