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.
