Abstract: An LED light fixture for a hazardous location includes an axially elongated enclosure fabricated from a polymer material, at least one axially elongated linear light emitting diode (LED) module mounted in the enclosure, and an LED driver module mounted in the housing that operates the at least one linear light emitting diode. A combination of a cover lens material of the cover lens and the polymer material of the axially elongated enclosure assists with heat dissipation from the light fixture, thereby allowing the LED driver module and the at least one axially elongated linear printed circuit board with LED components to operate within a target peak temperature limit for the hazardous location.

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.

Abstract: An LED light fixture for a hazardous location includes an axially elongated enclosure fabricated from a glassfiber reinforced plastic material, at least one axially elongated linear light emitting diode (LED) module mounted in the enclosure, and an LED driver module mounted in the housing that operates the at least one linear light emitting diode. The LED driver module and the at least one axially elongated linear LED module are operable within a target peak temperature limit for the hazardous location, without utilizing heat sinks to dissipate heat in order to provide acceptable thermal management.
