Mining explosion suppression and intrinsic safety type roadway lamp

Abstract

The invention belongs to the technical field of lighting equipment, and particularly relates to a mining explosion suppression and intrinsic safety type roadway lamp. The mining explosion suppressionand intrinsic safety type roadway lamp comprises a shell, a transparent part, an aluminum substrate, a lens and a nested part, wherein the aluminum substrate is contained in an intrinsic safety cavity, a positioning structure is arranged between the aluminum substrate and the lens to make the aluminum substrate and the lens relatively fixed; the nested part is in threaded connection with a lower shell body, a threaded explosion suppression surface is formed between the outer wall of the nested part and a threaded hole of the lower shell body, and a power source achieves grouped power supply toall groups of lamp beads through the nested part. The mining explosion suppression and intrinsic safety type roadway lamp has the advantages that since the positioning structure is arranged between the lens and the aluminum substrate, the aluminum substrate is compressed on the surface of the lower shell body through the lens, thereby simplifying the installation process; the intrinsic safety cavity is in transition connection with an explosion suppression cavity through the nested part, and the threaded explosion suppression surface is formed between the nested part and the lower shell body,which meets the explosion suppression requirement; the power source performs grouped power supply to all groups of lamp beads through the nested part, and the energy of each circuit is reduced through the grouped power supply.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, in particular to a mine explosion-proof and intrinsically safe roadway lamp. Background technique [0002] Factors such as the special danger and complexity of the environment in which explosion-proof electrical appliances are used, as well as maintenance and use time, all affect the comprehensive safety performance of explosion-proof electrical appliances. Therefore, in order to better ensure the safety of explosion-proof electrical appliances, it is necessary to The device undergoes a security upgrade. [0003] At present, most of the LED lighting fixtures used underground have the problems of complex structure, heavy weight, and short life. Their protection level is not high, and there are certain potential safety hazards. Contents of the invention [0004] The object of the present invention is to provide a mine explosion-proof and intrinsically safe roadway lamp, which aims to ...
