Description

Technical Field

[0001] This utility model belongs to the field of LED floodlight technology, specifically relating to an improved LED floodlight. Background Technology

[0002] A floodlight is a lighting fixture designed to provide illumination on a surface higher than the surrounding environment. It is also known as a spotlight. Typically, it can be aimed in any direction and is unaffected by weather conditions. It is mainly used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights. Floodlights have varying beam angles, ranging from 0° to 180°, with those having particularly narrow beams being called searchlights.

[0003] Currently, common LED floodlights only have one lighting fixture during installation, and their angle is difficult to adjust flexibly after installation, so they can only project light within a set range, resulting in limited effectiveness. Based on this, this utility model provides an improved LED floodlight. Utility Model Content
