[0002] A floodlight is a lamp with a higher illumination on the designated illuminated surface than the surrounding environment, and has a structure that is not affected by climatic conditions. It is mainly used in large-scale operations, mines, building outlines, stadiums, overpasses, monuments, parks and flower beds. The angle of the emitted beam of the floodlight is wide or narrow, ranging from zero to one hundred and eighty degrees. The existing floodlight has a one-sided illumination range. When a large area of ​​illumination is required, multiple floodlights need to be installed. Moreover, the floodlights are mostly fixed with bolts, and can only be limited to one position for illumination, which is not convenient for subsequent adjustment of the angle of illumination. For this reason, an LED explosion-proof floodlight is proposed. Utility Model Content
