[0002] A floodlight is a lamp with a higher illumination on the designated illuminated surface than the surrounding environment, also known as a spotlight. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area mines, building outlines, stadiums, overpasses, monuments, parks and flower beds.

[0003] Traditional floodlights with glass covers are prone to water ingress on rainy days, which can easily cause fogging, which can reduce the brightness of the lamps. Fog can also easily cause malfunctions, affecting the life of the lamps. In addition, the glass cover is at great risk of breakage during transportation. Therefore, aluminum cover drainage type floodlights have been developed in the prior art to solve the above problems, such as: a floodlight with an aluminum cover hidden drainage, whose application date is 2022-11-12 and application number is CN202223009234.1, which solves the problem of easy formation of fog and easy breakage inside the lamp. However, the shell of this floodlight is assembled from the lamp body outer shell and the lamp body back cover through a waterproof rubber ring and a back cover screw. The shell of this structure requires two sets of molds to be made, and then assembled manually, which has a high production cost. In addition, its upper bracket is installed on the lamp body outer shell through the upper bracket screws. When adjusting the angle, it is necessary to loosen the upper bracket screws first, and then tighten the upper bracket screws after adjusting them into place. Not only is the operation troublesome, but the adjusted position may also not be maintained due to the loosening of the upper bracket screws.

[0004] Based on this, the present application provides a new type of drainage floodlight with low production cost and convenient and reliable angle adjustment. Utility Model Content
