LED explosion-proof lamp with rapid pressure adjusting mechanism

Abstract

The invention relates to the technical field of LED lamps, in particular to an LED explosion-proof lamp with a rapid pressure adjusting mechanism. According to the technical scheme, the lamp comprises a shell, a lampshade assembly, an illumination assembly and a heat conduction assembly, the lampshade assembly is installed at the bottom of the shell, a protection plate is installed in the lampshade assembly, a convex lens is installed in the protection plate, a rubber sleeve is installed on the outer side of the convex lens, the illumination assembly is installed in the shell, and an installation plate is installed in the illumination assembly; a sealing plug is mounted on one side in the mounting plate, an exhaust hole is formed in one side in the mounting plate, and a one-way pipe is mounted at the bottom of the exhaust hole. The one-way pipe is mounted at the bottom of the exhaust hole, inert gas in the bottom space of the mounting plate can be actively exhausted under the influence of the air pressure difference through the one-way pipe, meanwhile, air above the mounting plate can be prevented from entering the bottom space of the mounting plate through the one-way pipe, and the air pressure of the inert gas in the space below the mounting plate can be conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an explosion-proof LED lamp with a rapid pressure adjustment mechanism. Background technique [0002] Explosion-proof lamp is a kind of lighting equipment with high protection level used in industrial production or geological mining and other places. By using explosion-proof lamp with LED light source for lighting, it can reduce the electric energy required for lighting and increase the lighting effect at the same time. Therefore, In order to enhance the practicability of the explosion-proof lamp, we propose a LED explosion-proof lamp with a pressure quick adjustment mechanism. [0003] After retrieval, the patent notification number is CN205447427U, which discloses a LED explosion-proof lamp, including a body, an LED assembly, an electrical assembly and a light-transmitting assembly. The body and the light-transmitting component form a sealed space, the LED component and the ...

AI Technical Summary

Problems solved by technology

[0005] 1. During the use of the existing LED explosion-proof lamps, in order to enhance the protective performance of the explosion-proof lamps, a certain amount of inert gas will be injected into the interior of the device to protect the lamps and avoid the occurrence of arcs inside the device that will affect the use of the lamps. The safety in the process, while the existing equidistance cannot automatically balance the internal inert gas pressure, making the internal pressure of the inert gas too high to affect the structural strength of the device;

[0006] 2. When the existing LED explosion-proof lamps use LED point light sources for lighting, the traditional LED lamp beads work in the form of multiple groups of lamp beads being energized and emitting light, which leads to relatively scattered light, and the lighting effect of the lamps is not ideal. The light diffusion range is large, the light is not concentrated enough, and the brightness cannot meet the existing needs
