Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment technology, and in particular to a waterproof LED light-emitting module. Background Technology

[0002] In the modern lighting and display field, LED light-emitting modules have been widely used due to their many advantages such as energy saving, long life, high brightness and rich colors. LED light-emitting modules are usually composed of multiple LED beads, circuit boards and related driving circuits, and can be combined into various shapes and sizes according to different needs.

[0003] In outdoor environments, LED light-emitting modules are widely used to achieve various lighting and display effects. Although existing LED light-emitting modules undergo some sealing treatment, due to the assembly process and structural characteristics of LED light-emitting modules, some gaps and interfaces are unavoidable. During long-term outdoor use, affected by natural factors such as wind, sun, and rain, the sealing materials at these gaps and interfaces are prone to aging and deformation, resulting in a decrease in sealing performance. This allows water to easily enter the module. Furthermore, LED light-emitting modules have channels on the housing for cable outgoing, which are the channels connecting the inside and outside of the housing. Sealing these channels is difficult. If improper operation during cable installation damages the sealing structure, gaps will be left, making it easy for rainwater to enter the housing later. Utility Model Content
