Abstract

The present invention relates generally to a lighting apparatus for hazardous locations. In one embodiment, the lighting apparatus comprises a light engine, a heat sink coupled to the light engine, a stalk coupled to the light engine for externally coupling a power supply to the light engine and an electrical wiring splice box coupled to the stalk.

Claims (24)

1. A lighting apparatus, comprising:

a light engine comprising one or more light emitting diodes (LEDs);

a heat sink coupled to said light engine;

a stalk coupled to said light engine for externally coupling a power supply to said light engine; and

an electrical wiring splice box coupled to said stalk, wherein said electrical wiring splice box comprises a back plate, wherein said back plate is configured for mounting said lighting apparatus to a second lighting apparatus in a back to back configuration.

2. A lighting apparatus, comprising:

a light engine comprising one or more light emitting diodes (LEDs);

a heat sink coupled to said light engine;

a stalk coupled to said light engine for externally coupling a power supply to said light engine; and

an electrical wiring splice box coupled to said stalk, wherein said electrical wiring splice box comprises a plurality of holes, wherein said holes are configured for in and out conduits for wall mounting.

3. A lighting apparatus, comprising:

a light engine comprising one or more light emitting diodes (LEDs);

a heat sink coupled to said light engine;

a stalk coupled to said light engine for externally coupling a power supply to said light engine; and

an electrical wiring splice box coupled to said stalk, wherein said electrical wiring splice box comprises a plurality of holes, wherein said holes are configured for pendant mounting.

4. A lighting apparatus, comprising:

a light engine; and

a power supply that provides power to said light engine such that heat generated by said power supply is isolated away from said light engine, wherein an electrical wiring splice box comprises a back plate, wherein said back plate is configured for mounting said lighting apparatus to a second lighting apparatus in a back to back configuration.

5. A lighting apparatus, comprising:

a light engine; and

a power supply that provides power to said light engine such that heat generated by said power supply is isolated away from said light engine, wherein an electrical wiring splice box comprises a plurality of holes, wherein said holes are configured for in and out conduits for wall mounting.

6. A lighting apparatus, comprising:

a light engine; and

a power supply that provides power to said light engine such that heat generated by said power supply is isolated away from said light engine, wherein an electrical wiring splice box comprises a plurality of holes, wherein said holes are configured for pendant mounting.
