[0002] A floodlight is a lamp with a higher illumination on the designated back 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 for large-scale mines, building outlines, stadiums, overpasses, monuments, parks and flower bed lights. The structure of a traditional floodlight is generally composed of a radiator, LED lamp bead board, power supply, reflector cup, glass, lens, silicone ring, bracket and other parts. There are many processes in the assembly of this structure of floodlights, and all components are mainly fixed with screws. This structure of floodlights has the following shortcomings: 1. Low assembly efficiency, difficult to achieve production automation, and low output. 2. The waterproofing of the product mainly depends on the silicone ring. During the assembly process, if there is a place that is not in place, it is very easy to get water in and cause permanent damage to the product. 3. The structure of the product is mainly composed of a radiator, LED lamp bead board, power supply, reflector cup, glass, lens, silicone ring, etc. After the LED lamp beads are lit, they are reflected by the reflector cup, then through the glass or lens, and then illuminated to the irradiated object. After several twists and turns, the light loss is more than 20%. 4. The closed structure design mainly uses aluminum lamp body for heat dissipation. A large amount of heat is stored inside the lamp body and cannot be dissipated. If better heat dissipation is required, more aluminum is needed to make the lamp body, which is not conducive to mass production. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Utility Model Content
