Abstract

The invention discloses an LED lighting module. The LED lighting module comprises a cooling fin, an LED lamp panel, a lens surface cover and protective glass, the lens surface cover is provided with an inner surface close to the LED lamp panel and an outer surface close to the protective glass, and the periphery of the inner surface and the periphery of the outer surface are each provided with at least one circle of groove used for being filled with liquid silica gel; and a plurality of buckle type connecting pieces are arranged on the edge of the outer surface of the lens surface cover and used for fixing protective glass, and through holes are formed in the protective glass and used for releasing air trapped when the protective glass and the lens surface cover are bonded. The lighting module has the beneficial effects that: installation is easy and convenient, moving and overturning are achieved after glue dispensing, the protective glass is not prone to displacement, the production efficiency is high, and the situation that the protection grade is easy to decrease due to air trapping is reduced.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lighting module. Background technique [0002] In order to facilitate installation and maintenance, traditional LED street lamps use modular LED modules to assemble lamps and lanterns. It has become a common practice for manufacturers. Because liquid silicone is used to replace the sealing ring, it has the advantages of fast operation and better sealing performance. However, due to the need for curing During the production process, the modules after dispensing are dislocated, or the glue is left to wait for the glue to cure after dispensing, resulting in low production efficiency; and during the glue curing process, due to the gap between the protective glass and the lens cover Due to the influence of trapped air, the protective glass cannot fit tightly with the lens cover, resulting in a lower protection level than the design requirement. Contents of the invention [0003] ...
