Mine explosion-proof straight LED (light-emitting diode) lamp

Abstract

The invention provides a mine explosion-proof straight LED (light-emitting diode) lamp which comprises an LED light source, an explosion-proof cavity, an LED heat radiation plate and the like, wherein the LED heat radiation plate is a semicircular heat radiation plate, a fin body of the heat radiation plate, which is a housing of the LED lamp, is arranged on the LED heat radiation plate, and the non-circumferential part is linked with a semi-circular strip-shaped anti-static light transparent cover; the explosion-proof cavity comprises an explosion-proof cavity body, a lower housing linked at the right end of the explosion-proof cavity body and the like, an intrinsically safe power supply component is arranged in the explosion-proof cavity, and the explosion-proof cavity is linked with the heat radiation plate through the lower housing; and an LED lamp light source is arranged at the non-circumferential part of the heat radiation plate and comprises two rows of LED light source parts with an included angle of 30 degrees. The mine explosion-proof straight LED lamp has the benefits of having large heat radiation surface, improving heat radiation performance of the LED lamp light source, prolonging service life of the LED lamp, reducing shading, being convenient to clean and scrub, increasing a light source divergence angle, enlarging illuminated area of a laneway, being convenient to detach and install and being easy to maintain.

Description

technical field [0001] The invention relates to a mine explosion-proof straight LED lamp, which belongs to coal mine roadway lighting equipment. Background technique [0002] At present, mine explosion-proof straight LED lamp roadway lights have been widely used in coal mine roadway lighting, but mine explosion-proof straight LED lamps generally have a two-chamber explosion-proof structure, including LED light source, lampshade, housing, LED heat dissipation board, etc., the lampshade is a fully enclosed tempered glass light-transmitting cover, connected to the shell, the LED heat sink is completely enclosed in the lampshade, the LED light sources are arranged on the LED heat sink in a word, and the welding interval of 4 external use is greater than 5 cm. The wire mesh is tightened, and a fixed circuit board is installed in the housing. Once the LED light fails, the power supply must be cut off, which is inconvenient to disassemble and install, and difficult to maintain; th...
