Description

Technical Field

[0001] This utility model relates to the technical field of drivers, specifically to an LED driver. Background Technology

[0002] As a core component of lighting equipment, the performance of the LED driver directly affects the stability and lifespan of the entire lighting system. In practical applications, LED drivers are often exposed to various harsh environments, such as humidity and dust, which can damage the internal circuitry and affect their normal operation. Furthermore, for ease of installation and maintenance, the driver's assembly structure must also be designed for quick and convenient installation.

[0003] Currently, most LED drivers on the market use simple housing encapsulation structures. In terms of assembly, screw fixing or snap-fit ​​structures are usually used to assemble and disassemble the driver. Although the traditional screw fixing method is reliable, it is complicated and time-consuming to operate. The simple snap-fit ​​structure, due to the lack of positioning function, cannot guarantee quick alignment during installation and long-term stability. The side plates of existing LED drivers are all set on the cover. When potting and sealing are required, glue often overflows, and glue removal is required during assembly, which affects assembly efficiency. Utility Model Content
