Anti-explosion light source assembly of LED lamp

Abstract

An anti-explosion light source assembly of an LED lamp comprises a lamp bar cover, a light source assembly, a heat dissipation piece, an end cover and a pouring piece. The light bar cover comprises a cover body, a pouring groove, a light source groove, clamping fingers and a hook. The two clamping fingers are arranged at the bottom of the pouring groove in the extending direction of the pouring groove, and the two clamping fingers are arranged in a spaced mode and face the opposite direction. The clamping fingers are clamped with the clamping grooves in the two sides of the heat dissipation piece so that the heat dissipation piece and the cover body are connected and fixed before the pouring piece is formed in a pouring mode, sealing of the light source groove is guaranteed, and the connecting strength of the heat dissipation piece and the cover body is improved. Meanwhile, the pouring solution can be prevented from leaking into the light source groove, and the sealing performance is further improved. The two grooves in the two sides of the heat dissipation piece and the two hooks in the pouring groove can enable the pouring piece to be mutually fastened with the heat dissipation piece and the pouring piece.

Description

technical field [0001] The invention relates to the technical field of explosion-proof lamps, in particular to an explosion-proof light source assembly of an LED lamp. Background technique [0002] Explosion-proof lamps refer to lighting fixtures that use explosion-proof technology. They are often used in environments where flammable gases and dust exist. Explosion-proof requirements, so the sealing heat dissipation effect and structural strength of the light source in the explosion-proof lamp are particularly important. The light source of traditional explosion-proof lamps is mostly to install a transparent cover outside the LED lamp to isolate and seal the LED lamp from the outside world. Components, and the LED lamp is isolated and sealed from the outside world, so as to prevent flammable factors such as arc sparks from contacting with flammable gases outside, and prevent explosion. However, the existing lamps are only sealed in a circle, and pouring is performed on the...

AI Technical Summary

Problems solved by technology

Although the LED light strip is sealed from the outside world, only a circle of injection compound is poured between the heat sink and the lampshade, and the sealing effect is low

And after a long time, the glue injection compound is prone to failure, making the heat sink and the lampshade loose or even separated, exposing the LED strip to the external environment, affecting the sealing and explosion-proof performance
