Coal mine underground roadway lighting fixtures

Abstract

The invention discloses a lighting fixture for an underground roadway in a coal mine, which comprises a light source and a mounting belt for fixing the light source. The extending directions of the mounting belts are uniformly distributed, and the distance between two adjacent light sources is smaller than the distance that any one of the light sources can illuminate. That is to say, several light sources are evenly installed along the extension direction of the roadway to form a light strip, and there is an area of ​​repeated lighting between two adjacent light sources, which effectively avoids the situation that the illumination under the roadway lights is too high and there is a dark area between the two lights, and realizes the realization of coal mines. The underground roadway has no interval and uniform lighting effect, which improves the safety of underground operation in coal mines.

Description

technical field [0001] The invention relates to the technical field of coal mine production, in particular to a coal mine underground roadway lighting lamp. Background technique [0002] There are two types of lighting lamps used in most coal mines in China: mining explosion-proof lighting and mining explosion-proof and intrinsically safe lighting fixtures. The lighting source has successively experienced incandescent lamps, fluorescent lamps, energy-saving lamps, and LED light sources. Among them, mine explosion-proof lamps are equipped with a protective metal mesh outside the explosion-proof glass cover, which is fixed on the lamp housing; mine explosion-proof and intrinsically safe type is that the light source is intrinsically safe, and the wiring cavity and switch part are explosion-proof type. The above two kinds of underground roadway lamps are all powered by mine lighting comprehensive protection, the power supply voltage is generally 127V, and a roadway lamp is gen...

AI Technical Summary

Problems solved by technology

[0004] The metal mesh outside the explosion-proof lamp has a large gap, which may damage the glass cover, thus losing the explosion-proof performance, and electric sparks generated by electrical parts such as filaments cause coal dust and gas explosions, posing safety hazards;

[0005] The light source of the original roadway lights consumes a lot of power and has a short service life, and the power supply voltage is 127V, which is an unsafe voltage;

[0006] There is a certain distance between the roadway lights, so that the brightness under the lights is too high in the whole roadway, and there is a dark area between the two lights, and the brightness is uneven;

[0007] The lighting of the existing excavation roadway mainly depends on the lighting of the miner's lamp and the front and rear lights of the roadheader. Therefore, the lighting of the excavation roadway is dim and the range is narrow, and it is difficult to guarantee the safety of the excavation.
