Outdoor high-weatherability waterproof and dustproof LED light-emitting module

Abstract

The invention discloses an outdoor high-weatherability waterproof and dustproof LED light-emitting module which comprises a structural member, a clamping groove, cooling teeth, meshing teeth, an LED lamp strip, LED lamp beads, a light guide plate and a light guide plate light-outlet face. The clamping groove is formed in the inner side of the structural member. The cooling teeth are arranged on the surface of the left end of the structural member. The meshing teeth are arranged at the upper end and the lower end of the inner side of the structural member. The LED lamp strip is arranged at theleft end of the inner side of the clamping groove. The LED light-emitting module is an LED side-in type back light module, and through the cooperation of the structural member, the LED lamp strip andthe light guide plate, the module can prevent water and dust and can also have quite high light efficiency and uniformity to replace a traditional outdoor lamp product; the side-in light type light guide module improves the light efficiency and light uniformity compared with a traditional waterproof lampshade; through the meshing structure of the structural member, sealant and the structural member are meshed together, and the sealant ageing and disengaging risk is reduced; the module is simple in structure, simple and attractive in appearance and easy to assemble and can be used without othersubsequent procedures.

Description

technical field [0001] The invention relates to the related field of LED light-emitting modules, in particular to an outdoor waterproof and dust-proof LED light-emitting module with high weather resistance. Background technique [0002] Outdoor lighting, such as high-rise buildings, parks, squares, pedestrian bridges, underground passages and other outdoor lighting projects, the lamps and lanterns are exposed to the environment, the sun and rain, the construction of outdoor lighting projects is difficult, once there is a problem, the maintenance cost is huge, so outdoor lighting is required Excellent electrical performance and protection level. [0003] Existing building exterior lights usually use lamp panels or lamp posts, the back is a sheet metal structure, and a layer of PC protective cover is wrapped on the light-emitting side, so that the light can be emitted through the protective cover. Screw hole plus sealing rubber ring connection [0004] However, the existing ...

AI Technical Summary

Problems solved by technology

[0005] 1. If it is used for too long, the sealing rubber ring will age, the screws and other sheet metal connectors will rust, the electrical performance and sealing performance will decrease, and it will be easily damaged

[0006] 2. In order to have a good haze and make the light shine evenly and softly, the light transmittance of the protective cover is very low, resulting in low light efficiency
