Pouring and packaging type LED anti-explosion light source module and anti-explosion lamp

Abstract

The invention discloses a pouring and packaging type LED anti-explosion light source module and an anti-explosion lamp. The pouring and packaging type LED anti-explosion light source module comprises a mounting board, a light source assembly and an anti-explosion packaging adhesive; a mounting groove is formed in the back surface of the mounting board; pouring and packaging holes which run through to the front surface of the mounting board are formed in the bottom wall of the mounting groove; the light source assembly comprises a light source substrate and an LED chip fixedly arranged on the front surface of the light source substrate; a bonding pad electrically connected with the LED chip is fixedly arranged on the periphery of the LED chip on the light source substrate; the light source substrate is adaptively clamped in the mounting groove, and connected with the mounting board in a sealing manner; the LED chip and the bonding pad are both positioned in the pouring and packaging holes; the pouring and packaging holes are formed in the front surface of the light source substrate in a surrounding manner to form a pouring and packaging cavity; and the pouring and packaging cavity is filled with the anti-explosion packaging adhesive. By virtue of the technical scheme, the anti-explosion performance of the LED anti-explosion lamp is improved, so that the applicable range of the LED anti-explosion lamp is wider.

Description

technical field [0001] The invention relates to the technical field of explosion-proof lighting, in particular to a potting-type LED explosion-proof light source module and an explosion-proof lamp. Background technique [0002] At present, explosion-proof lighting fixtures are required in many places such as coal mines, petroleum, chemical industry, ships and offshore platforms. Compared with traditional high-pressure sodium lamps, metal halide lamps, and incandescent light sources, LED light sources have been widely used in the field of explosion-proof lighting technology in recent years because of their long service life and energy-saving advantages. However, the current common LED explosion-proof lamps continue the design scheme of traditional lamps in terms of explosion-proof principles. The explosion-proof requirements can only be met through the thick and heavy casing, the wide explosion-proof surface and the cooperation of the whole lamp and various parts. The cost o...

Problems solved by technology

However, the current common LED explosion-proof lamps continue the design scheme of traditional lamps in terms of explosion-proof principles. The explosion-proof requirements can only be met through the thick and heavy shell, the wide explosion-proof surface and the cooperation of the whole lamp and various parts. The cost of the shell is high, and the explosion-proof performance is low, which limits the application range of LED explosion-proof lamps.
