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.
