Abstract

An LED light fixture for a hazardous location includes an axially elongated enclosure, a first axially elongated printed circuit board with light emitting diode (LED) components mounted in the axially elongated enclosure, a second axially elongated printed circuit board with LED components mounted in the axially elongated enclosure, and an LED driver module mounted in the enclosure that operates the circuit boards. The LED driver module is (1) positioned laterally in a horizontal direction in the axially elongated enclosure at a location between the first axially elongated printed circuit board and the second axially elongated printed circuit board, and (2) elevated in a vertical direction in the axially elongated enclosure relative to the first and second axially elongated printed circuit boards.
