Abstract: In one embodiment, a LED module comprises a heat sink, a light source, a lens structure configured to enclose the light source by means of a sealing material, and a fastener assembly configured to removably attach the light source and the lens structure to the heat sink. The lens structure comprises a groove and one or more lenses. The groove surrounds the one or more lenses and is configured to receive the sealing material such that the sealing material seals a gap between the lens structure and the light source without attaching to the heat sink.

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.
