Abstract

A light fixture has a base that is connected to a housing through a wireway at its upper portion and a pair of offsets at its lower portion, and a stabilizer block that is located between the pair of offsets extends from the base to a recess in the housing's lower portion with a friction fit connection. The housing's lower portion has a thickened sidewall in which the recess is formed. The thickened sidewall also includes a pair of cavities with apertures where the offsets are fastened to the base. The stabilizer block and the wireway are aligned with each other in a longitudinal axis, and the stabilizer block and the offsets are aligned with each other along a lateral axis that is perpendicular to the lateral axis. The wireway is harder than the housing, and its threaded end engages the threaded aperture in the housing's upper portion.

Claims (38)

1 . A light fixture, comprising:

a base comprising a front side and a back side;

a housing, wherein the housing has an upper portion and a lower portion, wherein the lower portion comprises a pair of apertures in a periphery section facing the front side of the base and a recess in the periphery section between the pair of apertures;

a wireway connecting the upper portion of the housing to the base;

a pair of offsets extending from the front side of the base to the respective pair of apertures in the lower portion of the housing, wherein the pair of offsets maintain an open space between the front side of the base and the lower portion of the housing;

a pair of fasteners respectively extending through the pair of apertures and connecting the pair of offsets to the lower portion of the housing; and

a stabilizer block positioned between the pair of offsets and extending from the base to the lower portion of the housing, wherein a distal end of the stabilizer block fits within the recess.

2 . The light fixture of claim 1 , wherein the distal end of the stabilizer block has a friction fit with the recess.

3 . The light fixture of claim 1 , wherein the lower portion of the housing is comprised of a thickened sidewall surrounding the recess.

4 . The light fixture of claim 3 , wherein the thickened sidewall extends in the periphery section to surround the pair of apertures.

5 . The light fixture of claim 4 , wherein the pair of apertures are recessed in a pair of cavities in the thickened sidewall, and wherein the pair of offsets extend into the respective pair of cavities.

6 . The light fixture of claim 1 , wherein the stabilizer block and the wireway are aligned with each other in a longitudinal axis, and wherein the stabilizer block and the pair of offsets are aligned with each other along a lateral axis perpendicular to the longitudinal axis.

7 . The light fixture of claim 1 , wherein a housing end and a base end of the wireway are each comprised of a threaded distal end, wherein the base end of the wireway is further comprised of a flange and a spline between the flange and the threaded distal end, wherein the threaded distal end of the wireway's base end extends through a key aperture in the base with sidewalls that mate with the spline of the wireway, wherein a nut screws onto the threaded distal end at the back side of the base, and wherein the flange abuts the front side of the base.

8 . The light fixture of claim 7 , wherein the spline is comprised of pair of circular arc sections and a pair of flat sections extending between the pair of circular arc sections, wherein the upper portion of the housing is comprised of a threaded aperture, wherein the wireway is comprised of a harder material than the housing, and wherein the threaded distal end of the housing end of the wireway engages the threaded aperture as it is screwed into the housing.

9 . The light fixture of claim 1 , wherein the stabilizer block and the pair of offsets are integrally formed with the base, wherein the pair of offsets are tubular, and wherein the pair of fasteners connecting to the pair of offsets are a pair of screws.

10 . The light fixture of claim 9 , wherein the stabilizer block has a trapezoidal prism shape.

11 . A light fixture, comprising:

a base comprising a front side and a back side;

a housing, wherein the housing has an upper portion and a lower portion, wherein the lower portion comprises a pair of apertures in a periphery section facing the front side of the base and a recess in the periphery section between the pair of apertures;

a wireway connecting the upper portion of the housing to the base;

a pair of offsets extending from the front side of the base to the respective pair of apertures in the lower portion of the housing;

a pair of fasteners respectively extending through the pair of apertures and attaching the pair of offsets to the lower portion of the housing; and

a stabilizer block positioned between the pair of offsets and extending from the base to the lower portion of the housing, wherein a distal end of the stabilizer block has a friction fit within the recess and does not extend through the periphery section.

12 . The light fixture of claim 11 , wherein the lower portion of the housing is comprised of a thickened sidewall in the periphery section surrounding the recess and the pair of apertures, wherein the pair of apertures are recessed in a pair of cavities in the thickened sidewall cross-section, and wherein the pair of offsets extend into the respective pair of cavities.

13 . The light fixture of claim 11 , wherein the stabilizer block and the wireway are aligned with each other in a longitudinal axis, and wherein the stabilizer block and the pair of offsets are aligned with each other along a lateral axis perpendicular to the longitudinal axis.

14 . The light fixture of claim 11 , wherein a housing end and a base end of the wireway are each comprised of a threaded distal end, wherein the base end of the wireway is further comprised of a flange and a spline between the flange and the threaded distal end, wherein the threaded distal end of the wireway's base end extends through a key aperture in the base with sidewalls that mate with the spline of the wireway, wherein a nut screws onto the threaded distal end at the back side of the base, and wherein the flange abuts the front side of the base.

15 . The light fixture of claim 11 , wherein the pair of offsets maintain an open space between the front side of the base and the lower portion of the housing.

16 . The light fixture of claim 11 , wherein the pair of offsets are tubular, and wherein the pair of fasteners connecting to the pair of offsets are a pair of screws, and wherein the stabilizer block has a trapezoidal prism shape.

17 . A light fixture, comprising:

a base comprising a front side and a back side;

a housing, wherein the housing has an upper portion and a lower portion, wherein the lower portion comprises a pair of apertures in a periphery section facing the front side of the base and a recess in the periphery section between the pair of apertures;

a wireway connecting the upper portion of the housing to the base;

a pair of offsets integrally formed with the base and extending from the front side of the base to the respective pair of apertures in the lower portion of the housing, wherein the pair of offsets are tubular;

a pair of screws respectively extending through the pair of apertures and attaching the pair of offsets to the lower portion of the housing; and

a stabilizer block positioned between the pair of offsets and extending from the base to the lower portion of the housing, wherein the stabilizer block has a trapezoidal prism shape, and wherein a distal end of the stabilizer block has a friction fit within the recess.

18 . The light fixture of claim 17 , wherein the lower portion of the housing is comprised of a thickened sidewall in the periphery section surrounding the recess and the pair of apertures, wherein the pair of apertures are recessed in a pair of cavities in the thickened sidewall cross-section, and wherein the pair of offsets extend into the respective pair of cavities.

19 . The light fixture of claim 17 , wherein the stabilizer block and the wireway are aligned with each other in a longitudinal axis, and wherein the stabilizer block and the pair of offsets are aligned with each other along a lateral axis perpendicular to the longitudinal axis.
