Abstract: Provided in the present invention is an explosion-proof lighting device, comprising: a device body for accommodating the explosion-proof lighting device, the device body comprising a mounting portion located in the middle portion thereof and a first heat dissipation portion and a second heat dissipation portion that extend from the bottom of the mounting portion to two sides; a plurality of light emitting diodes (LEDs) for emitting light to illuminate; an electrical drive module for powering the light emitting diodes; and a seal cover detachably connected to the device body from the bottom thereof. The present invention allows for reliable dissipation of heat generated by the light emitting diodes to the ambient environment without additionally providing a heat dissipation device, avoids the direct adverse effects of heat generated by the light emitting diodes on the electrical drive module while achieving compactness and reduced height of the explosion-proof lighting device, and significantly reduces the number of parts and costs for production, assembly and manufacturing of the explosion-proof lighting device.
