AI Technical Summary

Technical Problem

Existing modular streetlights are prone to aging and displacement of their sealing rings when exposed to harsh environments for extended periods. This leads to changes in gaps, affecting the stability of waterproof performance. Furthermore, replacing the sealing rings is a complex and time-consuming process.

Method used

A modular outdoor waterproof street light was designed, which adopts a limiting rod, positioning sleeve and pressure sleeve structure to allow the light-emitting panel to move laterally to facilitate the replacement of the sealing ring. The combination design of the limiting rod and positioning sleeve keeps the panel connected to the housing and simplifies the process of disassembling the sealing ring.

Benefits of technology

It enables quick replacement of the sealing ring, reduces operation difficulty and time, improves replacement efficiency, maintains stable connection of the light-emitting panel, and extends the service life of the equipment.

Abstract

The utility model discloses a modularized outdoor waterproof street lamp, which relates to the field of waterproof street lamps, and comprises a shell and two light-emitting panels embedded in the lower surface of the shell, two sealing rings are fixed on the lower surface of the shell, the sealing rings are distributed on the edges of the light-emitting panels, positioning hoops are fixed on the light-emitting panels, and the positioning hoops are fixed on the two sides of the shell. And the positioning hoops pass through the sealing ring and extend to the upper part of the shell. In the process of disassembling the light-emitting panel, the light-emitting panel can be operated to transversely move away from the original installation position, a space for disassembling the sealing ring is reserved, and then the sealing ring is disassembled. After the light-emitting panel transversely moves to be away from the original installation position, connection between the light-emitting panel and the shell can still be kept, the falling phenomenon of the light-emitting panel is avoided, the sealing ring can be conveniently and rapidly replaced in time, the light-emitting panel does not need to be held by hand for a long time in the replacement process, the operation difficulty is lowered, and the replacement operation efficiency is improved.
