Abstract

A linear 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 linear 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.

First claim

What is claimed is:

1. A linear light fixture comprising:
a housing body,
at least one light emitting diode attached to the housing body,
at least one of a power convertor and a power storage device attached to the housing body and configured to supply electric power to the at least one light emitting diode,
a conduit within the housing body that extends along the length of the housing body from a first end of the linear light fixture to a second end of the linear light fixture, and
wherein one of at least one wire is arranged in the conduit electrically connecting said at least one of the power convertor and power storage device to said at least one light emitting diode, a first end of the one of at least one wire extending out of the conduit via a driver access pocket to connect to said at least one of the power converter and power storage device, a second end of the one of at least one wire extending out of the conduit via a lighting access pocket to connect to said at least one light emitting diode.

2. The linear light fixture of claim 1 , further comprising a lens enclosing the at least one light emitting diode and the lighting access pocket, and a driver housing enclosing the at least one of the power convertor and power storage device and the driver access pocket.

3. The linear light fixture of claim 1 , further comprising potting arranged in at least one of the driver access pocket and the lighting access pocket.

4. The linear light fixture of claim 3 , further comprising a grommet arranged in the conduit and configured to control a flow of the potting compound.

5. The linear light fixture of claim 1 , wherein the conduit facilitates an explosion-proof enclosure.

6. The linear light fixture of claim 1 , wherein another one of the at least one wire enters the light fixture at a first end and exits the light fixture at a second end opposite the first end.

7. The linear light fixture of claim 1 , wherein another one of the at least one wire is from an internal power source.

8. The linear light fixture of claim 1 , wherein another one of the at least one wire is from an external power source.

9. The linear light fixture of claim 1 , wherein the housing body includes at least one aperture that provides access to the at least one wire extending through the conduit.

10. A linear light fixture comprising:
a housing body; and
a conduit formed within the housing body and extending along a length of the housing body, within which one of at least one wire extends to connect at least one of a power convertor and a power storage device to at least one light emitting diode; wherein
a first end of the one of at least one wire extends out of the conduit via a driver access pocket to connect to said at least one of the power converter and power storage device, a second end of the one of at least one wire extends out of the conduit via a lighting access pocket to connect to said at least one light emitting diode.

11. The linear light fixture of claim 10 , wherein the housing body includes a recessed lighting compartment within which the at least one light emitting diode is located.

12. The linear light fixture of claim 10 , wherein the conduit runs the entire length of the extruded housing body.

13. The linear light fixture of claim 12 , further including potting compound within the conduit, the potting compound being configured to seal at least a portion of the conduit.

14. The linear light fixture of claim 10 , wherein the conduit is sealed to create an explosion-proof enclosure.

15. The linear light fixture of claim 10 , wherein another one of the at least one wire enters the light fixture at a first end and exits the light fixture at a second end opposite the first end.

16. The linear light fixture of claim 10 , wherein the extruded housing body further comprises at least one eyelet.

17. The linear light fixture of claim 16 , wherein the light fixture is secured to a structure at least in part via a cable or lanyard attached to or through the at least one eyelet at a first end and attached to the structure at a second end, and wherein the structure is located in a direction orthogonal to the length of the extruded housing body.

18. A method of manufacturing the light fixture of claim 10 comprising:
forming the housing body as a single element by using an extrusion process; and
forming integrally extruded features within the housing body, wherein at least one of the integrally extruded features is the conduit in which the at least one wire can be placed, the conduit extending along the length of the light fixture.
