Flameproof LED roadway lamp for mines

Abstract

The invention relates to a flameproof LED roadway lamp for mines, which comprises a lamp shell (2), a copper cushion plate (3) and a transparent part (5) installed on the front face of the lamp shell and a pressing device pressing plate (4). The flameproof LED roadway lamp for mines comprises an electrical appliance assembly LED driving plate (15) and an insulating screw (10) installed in a wiring cavity. The flameproof LED roadway lamp for mines comprises a rear cover (11) and a rear cover (13) installed at the back face of the lamp shell, and the rear cover (13) and the rear cover (11) are connected in parallel to form an independent cavity. The flameproof LED roadway lamp for mines comprises a light-emitting assembly LED light source (6), an LD aluminum base plate (8) and an LED lens (7). The light emitting angle of the lens is 95*130 DEG, 4 rows of 16 flameproof LED roadway lamps for mines are arranged in parallel, light distribution is rectangular aperture, the installation distance of adjacent lamps is extended, the use quantity of the lamps is reduced, the lens concentrates all discrete light in the space on a working face, and the illuminance of the working face is increased. The LED lamp bead is arranged in the center of the bottom face of each lens, the effective light distribution of 120-180 DEG discrete light emitted by LED is ensured, the utilization rate of light is increased, and the flameproof LED roadway lamp for mines also has the effect of preventing glare.

Description

technical field [0001] The present invention relates to a roadway lighting lamp, and more specifically relates to an LED roadway lamp which is especially suitable for use in coal mine underground roadways. Background technique [0002] At present, the LED roadway lights used in underground roadways have a convex hexagonal surface, 5 sided surfaces or a circular aperture. In the narrow and long underground roadways, the installation distance between lamps is short (not enough light distribution), and generally cannot exceed 10 meters, the number of installations needs to be large, which is not conducive to energy saving and increases the amount of maintenance. It affects the lighting needs of coal mines, brings a lot of inconvenience to production activities, and seriously affects production efficiency.
