Luminaire for use in harsh and hazardous locations
A light fixture is provided which includes a housing body onto which a bezel is attached. Semiconductor LEDs or other light emitting source that produce light when electrically powered are located behind a lens that is secured to the housing body by the bezel. One or more incandescent light bulbs that include an electric filament that produce light when electrified as well as one or more fluorescent bulbs that produce light based at least in part on the electrification and illumination of a plasma or gas can also be used as a source of illumination. For example, the light fixture can further include a driver housing that includes a driver housing cover to permit access to at least one driver and/or battery backup components located within the driver housing. There is also at least one window in the bezel which permits illumination of an area or object.
1. A light fixture comprising:
a housing body;
at least one bezel or housing mounted to the housing body, forming at least two sealed enclosures;
a conduit within the housing body, wherein the conduit is integrally extruded from the housing body;
a first pocket in the housing body communicating the conduit with a first of the at least two sealed enclosures; and
a second pocket in the housing body communicating the conduit with a second of the at least two sealed enclosures.
2. The light fixture of claim 1 , wherein the at least one bezel or housing comprises:
at least one bezel forming the first sealed enclosure with the housing body; and
at least one housing forming the second sealed enclosure with the housing body.
3. The light fixture of claim 2 , further comprising a power converter, battery power storage device, surge suppression device or circuit, light sensor, or a wire terminal connector in the second sealed enclosure.
4. The light fixture of claim 3 , further comprising at least one light emitting diode in the first sealed enclosure.
5. The light fixture of claim 1 , further comprising a wire passing from the first sealed enclosure to the second sealed enclosure through the first pocket, the conduit, and the second pocket.
6. The light fixture of claim 1 , wherein:
the at least one bezel or housing comprises at least two housings forming the first and second sealed enclosures with the housing body, and
each of the first pocket and the second pocket contains a power converter, battery power storage device, surge suppression device or circuit, light sensor, or a wire terminal connector.
7. The light fixture of claim 1 , further comprising a potting arranged in the first pocket and the second pocket.
8. The light fixture of claim 7 , further comprising a grommet arranged in the conduit and configured to control a flow of the potting.
9. The light fixture of claim 1 , wherein the light fixture is an explosion-proof enclosure.
10. A light fixture comprising:
a housing body;
a conduit integrally extruded from within the housing body, within which at least one wire extends; and
a first pocket and a second pocket formed within the housing body,
wherein a first end of the at least one wire extends out of the conduit via the first pocket and a second end of the at least one wire extends out of the conduit via the second pocket.
11. The light fixture of claim 10 , wherein the first end of the at least one wire is connected to at least one of a power converter, battery power storage device, surge suppression device or circuit, light sensor, and a wire terminal connector.
12. The light fixture of claim 11 , wherein the second end of the at least one wire is connected to at least one light emitting diode.
13. The light fixture of claim 10 , further comprising a potting within at least one of the first pocket and second pocket.
14. The light fixture of claim 10 , wherein the light fixture is an explosion-proof enclosure.
15. A method of manufacturing the light fixture of claim 10 , comprising:
forming the housing body as a single element by using an extrusion process;
forming integrally extruded features within the housing body, wherein at least one of the integrally extruded features is the conduit.
