In recent years, with the rapid development of the economy, the continuous improvement of humanistic quality and urban vitality, many cities have implemented lighting projects to brighten the high-rise buildings, public places, shopping malls, and urban landmarks in the bustling neighborhoods. Objects, etc., are generally installed outdoors with high-power LED lamps to irradiate them, because they are installed outdoors; there are very strict requirements on the waterproof performance of lamps, and there are two types of high-power LED waterproof lamps commonly used in the market at present: one It is to set a groove on the end surface of the opening of the metal lamp cup for placing the sealing rubber ring. The rubber ring is higher than the end surface, and a piece of transparent glass is installed in the hollow of a surface cover. There is a corresponding screw hole on the end face of the lamp cup and the cover, and the LED lamp is installed in the lamp cup, and the cover and the lamp body are tightly connected with screws to compress the glass sheet and the sealing rubber ring. The bottom of the lamp body is provided with two waterproof terminals to connect with the LED lamp wires. This design is adopted to achieve the purpose of waterproofing. The disadvantage of using screw connection is that the screw will shift and loosen after a long time, resulting in the glass sheet and the sealing rubber ring not being tightly pressed, which cannot meet the standard of complete sealing, and the exposed surface of the screw head will affect the appearance of the lamp. In order to overcome the above shortcomings, some manufacturers have designed another structure of LED waterproof lamps. A circle of convex edges is horizontally set around the inner tube wall of the front end of a tubular lamp body. The end pipe slides down along the pipe wall to the convex edge, and then pours a layer of epoxy resin glue to bond the light-transmitting glass sheet and the convex edge together, and then places the LED lamp connected to the heat sink in the lamp body, and finally in the A layer of epoxy resin glue is poured into the rear end of the heat sink to seal the rear end of the lamp body. This structural design is adopted to achieve the purpose of waterproofing. Although this design avoids the disadvantage of screw connection, because there is a layer of epoxy resin glue on the light-transmitting glass sheet, it is baked by the high temperature generated by the LED lamp for a long time, which will cause the epoxy resin glue to oxidize and turn yellow, which will affect the light transmission and make the LED lamp The brightness is greatly reduced.

Contents of the invention
