Abstract

A light fixture assembly includes a housing having an interior surface, a ballast mounted on the interior surface of the housing, a first reflector releasably coupled to the interior surface of the housing, the ballast being substantially enclosed between the housing and the first reflector when the first reflector is in a first, closed position and being exposed when the first reflector is in a second, open position spaced from at least a portion of the interior surface, a lens releasably coupled to the housing, the first reflector being substantially enclosed between the lens and the housing when the lens is in a first, closed position and substantially exposed when the lens is in a second, open position. This construction provides relatively easy and quick access to the ballast for replacement and from below the fixture if it is mounted in or on the ceiling.

Claims

1. A light fixture assembly comprising:

a housing having an interior surface;

a ballast mounted on said interior surface of said housing;

a first reflector releasably coupled to said interior surface of said housing,

said ballast being substantially enclosed between said housing and said first reflector when said first reflector is in a first, closed position and being exposed when said first reflector is in a second, open position spaced from at least a portion of said interior surface; and

a lens releasably coupled to said housing,

said first reflector being substantially enclosed between said lens and said housing when said lens is in a first, closed position and substantially exposed when said lens is in a second, open position.

2. The light fixture assembly of claim 1, wherein

said first reflector is pivotally coupled to said housing at one side.

3. The light fixture assembly of claim 2, wherein

said reflector remains mounted to said housing when said reflector is in said second, open position.

4. The light fixture assembly of claim 2, wherein

said lens is pivotally coupled to said housing at one side.

5. The light fixture assembly of claim 4, wherein

said lens remains coupled to said housing when said lens is in said second, open position.

6. The light fixture assembly of claim 1, wherein

said reflector extends at an angle from said interior surface of said housing when, coupled thereto.

7. The light fixture assembly of claim 1 and further comprising

a second reflector pivotally coupled to said interior surface of said housing and pivotable independent of said first reflector.

8. The light fixture assembly of claim 1 and further comprising

a lamp coupled to said housing and located between said first reflector and said lens.

9. The light fixture assembly of claim 1, wherein

angle from said interior surface of said housing when, coupled thereto.

10. A light fixture comprising:

a housing having a back wall, and a first side wall and a second side wall extending from said back wall;

a ballast mounted on said back wall of said housing;

a reflector coupled to said first side wall and releasably coupled to said back wall,

said ballast being located between said reflector and said back wall of said housing when said reflector is in a first, closed position and being exposed when said reflector is in a second, open position spaced from at least a portion of said back wall; and

a lens coupled to said first side wall and releasably coupled to said second side wall,

said reflector being substantially enclosed between said lens and said back wall when said lens is in a first, closed position and being exposed when said lens is in a second, open position spaced from at least a portion of said second side wall.

11. The light fixture of claim 10, wherein

said reflector is pivotally coupled to said first side wall.

12. The light fixture of claim 11, wherein

said lens is pivotally coupled to said first side wall.

13. The light fixture assembly of claim 11, wherein

said reflector remains coupled to said first side wall when said reflector is in said second, open position.

14. The light fixture assembly of claim 12, wherein

said lens remains coupled to said first side wall when said lens is in said second, open position.

15. The light fixture of claim 10, wherein

said reflector is releasably coupled to said back wall via at least ¼

turn fastener.

16. The light fixture of claim 10, wherein

said lens is releasably coupled to said second wall via a latch in said first, closed position.

17. The light fixture of claim 10 and further comprising

a lamp coupled to said housing and located between said reflector and said lens.

18. The light fixture of claim 10 and further comprising

a second reflector releasably coupled to said back wall, wherein said second reflector can be released from said back wall independent of said reflector coupled to said first side wall.
