The invention discloses a two-cavity LED explosion-proof lamp, and relates to the field of explosion-proof lamps. According to the technical scheme, the two-cavity LED explosion-proof lamp comprises a power source box; the battery box comprises a cabin body at the front part and a wiring harness barrel at the rear part; a power source is arranged in the bin body, heat dissipation columns are arranged between the power source and the inner side wall of the bin body for separation, and the front end of the wire harness cylinder communicates with the interior of the bin body. A light source circuit board is arranged on the front end face of the bin body and provided with a positioning hole, a wire pipe corresponding to the positioning hole is arranged on the front end face of the bin body, the outer end of the wire pipe is located in the positioning hole, and the inner end of the wire pipe is communicated into the bin body. An annular heat dissipation cover is arranged on the periphery of the light source circuit board and fixed to the front end face of the bin body, a transparent plate is arranged in the annular heat dissipation cover, and the transparent plate and the light source circuit board are arranged in a spaced mode. The light source circuit board and the power supply are respectively provided with two different spaces, so that superposition of generated heat after mutual transfer can be avoided, and the light source circuit board and the power supply respectively dissipate heat in respective areas.
Description
technical field [0001] The invention relates to the field of explosion-proof lamps, in particular to a two-cavity LED explosion-proof lamp. Background technique [0002] With the development of the economy and the progress of society, energy conservation has become an inevitable and social consensus. All kinds of electrical appliances are more and more developed in the direction of saving energy, being convenient to use, saving space, being safe and efficient, and having multiple functions in one machine. As an important member of industrial lighting appliances, LED explosion-proof lamps are no exception. [0003] LED explosion-proof lamps are composed of shells, lamp beads, batteries, etc. Conventional shell type light source cavity and power supply cavity share one shell, which can save a set of shells, but the heat emitted by the aluminum substrate and the heat emitted by the power supply will be superimposed, affecting the overall performance of the lamp.
