LED lamp shell and sealing method thereof

Abstract

The invention belongs to the technical field of LED illumination, and discloses an LED lamp shell and a sealing method thereof. The LED lamp shell comprises an upper cover body and a lower cover body.The edge of a cover shell of the upper cover body is provided with a protruding clamping edge, and first sawtooth grooves are uniformly formed in the clamping edge. The edge of a cover shell of the lower cover body is provided with a clamping groove, the clamping groove is provided with an inner clamping groove edge and an outer clamping groove edge, and the inner clamping groove edge is uniformly provided with second sawtooth grooves which are mutually staggered with the first sawtooth grooves. The clamping edge can be embedded in the clamping groove. The LED lamp shell is provided with thefirst sawtooth groove and the second sawtooth groove which are mutually staggered, when glue is poured, air bubbles in gaps can be eliminated by the mutually staggered sawtooth grooves, and the generation of air bubbles during gluing is avoided. Even if air bubbles appear, large air bubbles can be decomposed into small air bubbles through the sawtooth structure, and large air bubbles in the gluingseams are avoided. Therefore, the sealing performance is guaranteed, structural connection is firmer and more reliable, and the waterproof effect is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lamp housing and a sealing method thereof. Background technique [0002] Industrial and mining lamps refer to the general term for lamps used in factories, mines, warehouses or high-shed production areas. They usually need to work reliably in dusty and humid places for a long time. Therefore, in order to ensure a stable fixed and sealed structure, industrial and mining lamps are often used Glue sealing method is adopted. When the lamp shell of the miner's lamp is assembled and sealed, air bubbles will appear after the glue seal is cured, which will seriously affect the effect of the glue seal and the service life of the product, and the lamp shell is not stable during use. Usually, the bubbles come from the bubbles carried by the colloid itself during the glue mixing process, or the bubbles are formed due to the pressure of the small sealing slot during the glue fill...

AI Technical Summary

Problems solved by technology

In the prior art, for the air bubbles generated in the sealing groove during the glue filling process, the solution is to preheat some heaters or use a vibrator combined with ultrasonic waves to eliminate the air bubbles. These methods are costly, complicated to operate, and do not meet the requirements. Glue filling and sealing of lighting structures such as industrial and mining lamps to eliminate the need for air bubbles
