Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 220 words
A lighting fixture comprising a housing including a substantially planar housing base plate having side walls extending upwardly from said substantially planar housing base plate and terminating in a pair of inwardly projecting uppermost ends to cooperatively form an elongated cavity, a pair of supporting members disposed on the upper portion of said upperwardly projecting side walls each comprising a detent formed on the lower portion therefrom and a shelf extending inwardly formed on the upper portion thereof in spaced relation relative to said respective inwardly projecting uppermost ends, a substantially transparent material operatively supported on said oppositely disposed shelves, said supporting members further include an open channel threaded portion formed below said oppositely disposed shelves to partially receive a fastening member to affix a pair of end plates to opposite ends of said housing, and a tray having a substantially planar tray base plate and upwardly projecting side walls to cooperatively press fit slidingly within said detents, circuitry disposed on the lower surface of said substantially planar tray base plate and reflective shield and light source supported on the upper surface of said substantially planar tray base plate, the uppermost portions on opposite sides of said reflection shield disposed to engage said oppositely disposed shelves to press fit said reflective means between said tray and said oppositely disposed shelves.
Claim 2
Dependent Claim 220 words
A lighting fixture comprising a housing including a substantially planar housing base plate having side walls extending upwardly from said substantially planar housing base plate and terminating in a pair of inwardly projecting uppermost ends to cooperatively form an elongated cavity, a pair of supporting members disposed on the upper portion of said upperwardly projecting side walls each comprising a detent formed on the lower portion therefrom and a shelf extending inwardly formed on the upper portion thereof in spaced relation relative to said respective inwardly projecting uppermost ends, a substantially transparent material operatively supported on said oppositely disposed shelves, said supporting members further include an open channel threaded portion formed below said oppositely disposed shelves to partially receive a fastening member to affix a pair of end plates to opposite ends of said housing, and a tray having a substantially planar tray base plate and upwardly projecting side walls to cooperatively press fit slidingly within said detents, circuitry disposed on the lower surface of said substantially planar tray base plate and reflective shield and light source supported on the upper surface of said substantially planar tray base plate, the uppermost portions on opposite sides of said reflection shield disposed to engage said oppositely disposed shelves to press fit said reflective means between said tray and said oppositely disposed shelves.
Claim 3
Dependent Claim 32 words
The light fixture of claim 1 wherein said upperwardly projecting side walls of said housing diverge mutually outwardly relative to one another from opposing substantially parallel longitudinal edges of said base plate.
Claim 4
Dependent Claim 32 words
The lighting fixture of claim 1 wherein said reflective shield comprises a pair of concave portions defined on opposite sides of center line of said reflective shield extending substantially the length thereof.
Claim 5
Dependent Claim 33 words
The lighting fixture of claim 1 wherein an O-ring is pressed fitted between the upper surface of said transparent material and the lower surface of said inwardly projecting pair of said uppermost ends.
