Abstract: Lighting assemblies or lighting fixtures suitable for use in a hazardous location are provided. Generally, the lighting fixtures include a light source assembly, a heat sink, a driver housing or gear module, and a conductive sealing member between the light source assembly and the heat sink. The conductive sealing member has a thermal conductivity of at least about 6 Watts per meter-Kelvin, and/or a thermal impedance of less than about 0.21 degree-C. inch squared per Watt. The lighting fixtures have controlled directional heat transfer from the light source assembly to the exterior of the lighting fixture, while minimizing the heat transferred to the driver housing.

Abstract: Lighting assemblies or lighting fixtures suitable for use in a hazardous location are provided. Generally, the lighting fixtures include a light source assembly, a heat sink, a driver housing or gear module, a thermally conductive sealing member between the light source assembly and the heat sink, and a thermally nonconductive sealing member or a thermally semi-conductive sealing member positioned between the heat sink and the driver housing. The conductive sealing member has a thermal conductivity of at least about 6 Watts per meter-Kelvin, and/or a thermal impedance of less than about 0.21 degree-C inch squared per Watt. The lighting fixtures have controlled directional heat transfer from the light source assembly to the exterior of the lighting fixture, while minimizing the heat transferred to the driver housing.
