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, a power convertor and/or a power storage device attached to the housing body and configured to supply electric power to the at least one light emitting diode, and at least one wire electrically connecting the power convertor and/or power storage device to the at least one light emitting diode, wherein the housing body comprises an integrally extruded conduit, and wherein the at least one wire is arranged in the integrally extruded conduit.

2 . The linear light fixture of claim 1 , wherein the power convertor and/or power storage device and/or battery backup is arranged linearly adjacent to the at least one light emitting diode.

3 . The linear light fixture of claim 1 , wherein the housing body includes a driver access pocket and a lighting access pocket, and wherein the at least one wire extends through the integrally extruded conduit between the driver access pocket and the lighting access pocket.

4 . The linear light fixture of claim 3 , further comprising a lens enclosing the at least one light emitting diode and the lighting access pocket and a driver housing enclosing the power convertor and/or power storage device, and the driver access pocket.

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

6 . The linear light fixture of claim 5 , further comprising a grommet arranged in the integrally extruded conduit and configured to control a flow of the potting.

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

8 . The linear light fixture of claim 1 , wherein 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.

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

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

11 . A linear light fixture comprising:
an extruded housing body comprising an integrally extruded conduit within which at least one wire extends to connect a power convertor and/or a power storage device to an at least one light emitting diode.

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

13 . The linear light fixture of claim 11 , wherein the integrally extruded conduit runs an entire length of the extruded housing body.

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

15 . The linear light fixture of claim 11 , wherein the integrally extruded conduit facilitates an explosion-proof enclosure.

16 . The linear light fixture of claim 11 , wherein 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.

17 . The linear light fixture of claim 11 , wherein the extruded housing body further comprises at least one integral eyelet machined into the extruded housing body.

18 . The linear light fixture of claim 17 , 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 integral eyelet at a first end and attached to the structure at a second end.

19 . A linear light fixture comprising:
a housing body, at least one light emitting diode sealed in a first compartment of the housing body, and a power convertor and/or power storage device sealed in a second compartment of the housing body and configured to supply electric power to the at least one light emitting diode, the first compartment and the second compartment of the housing body being isolated such that any spark, ignition, or explosion in one of the first compartment or the second compartment is arrested within the first compartment or the second compartment.

20 . The linear light fixture of claim 19 , further comprising at least one wire electrically connecting the power convertor and/or power storage device to the at least one light emitting diode, wherein the housing body comprises an integrally extruded conduit, and wherein the at least one wire is arranged in the integrally extruded conduit.

21 . The linear light fixture of claim 19 , wherein the power convertor and/or power storage device is arranged linearly adjacent to the at least one light emitting diode.

22 . The linear light fixture of claim 19 , wherein the housing body includes a driver access pocket and a lighting access pocket, and wherein the at least one wire extends through the integrally extruded conduit between the driver access pocket and the lighting access pocket.

23 . The linear light fixture of claim 22 , further comprising a lens enclosing the at least one light emitting diode and the lighting access pocket and a driver housing enclosing the power convertor and/or power storage device, and the driver access pocket.

24 . The linear light fixture of claim 22 , further comprising a potting arranged in at least one of the driver access pocket and the lighting access pocket.

25 . The linear light fixture of claim 24 , further comprising a grommet arranged in the integrally extruded conduit and configured to control a flow of the potting.

26 . The linear light fixture of claim 19 , wherein the integrally extruded conduit facilitates an explosion-proof enclosure.

27 . The linear light fixture of claim 19 , wherein 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.
