Abstract

The invention discloses an explosion-proof lamp and a light source assembly thereof. The light source assembly comprises a heat sink which is in a multi-face pyramid shape and a plurality of light-emitting units. The heat sink comprises a top wall with an opening, a plurality of side walls and protruding edges, wherein the periphery of the top wall extends to form the side walls, and the tail ends of the side walls extend horizontally to form the protruding edges. Each light-emitting unit is correspondingly arranged on the corresponding side wall of the heat sink and comprises a substrate and LED light sources arranged on the front face of the substrate, wherein the back face of the substrate is correspondingly attached to the surface of the outer side of the side wall of the heat sink. The substrate assemblies where the LED light sources are attached are annularly arranged on the heat sink, and therefore the annular illumination effect of the lamp is achieved, and meanwhile the size is small and installation is convenient.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an explosion-proof lighting fixture and a light source assembly thereof. Background technique [0002] In order to meet the lighting requirements of various explosion-proof occasions, there are more and more requirements for explosion-proof lamps. The defects of the explosion-proof lamps in the prior art include: single light distribution of the lamps, large volume and inconvenient installation. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the above-mentioned prior art, and propose an explosion-proof lamp with simple structure, small volume and convenient installation. [0004] In order to solve the above-mentioned technical problems, the present invention proposes a light source assembly of an explosion-proof lamp, including a heat sink, which is in the shape of a polygonal pyramid,...
