Description

High-power LED projection lamp

Technical Field

The utility model relates to the technical field of projection lamps, in particular to a high-power LED projection lamp.

Background

The projector is a lamp that specifies that the illuminance on the illuminated surface is higher than that in the surrounding environment. Also known as spotlights. In general, it can be aimed in any direction and has a structure that is not affected by the climatic conditions. The method is mainly used for large-area operation field mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and the like.
