Abstract

A retrofit LED lighting fixture for retrofitting alight source in a small recessed area. The retrofit LED lighting fixture has a junction box (200) installable through a luminaire housing (100) to fit within the small recessed area. A light engine module (300) is removably attached within the luminaire housing (100).

Claims

1. A retrofit LED lighting fixture, comprising:

a luminaire housing having an opening, said luminaire housing having a top wall opposite said opening;

said luminaire housing defining an internal cavity;

said luminaire housing having a first side member positioned between said opening and said top wall, said first side member having a junction box aperture;

a junction box containing a power supply, said junction box matingly received in said junction box aperture of said luminaire housing;

said junction box having a face plate removably affixed to said junction box by at least one affixation mechanism;

a light engine module removably retained within said internal cavity of said luminaire housing, said light engine module having at least one LED;

a side wall;

a light exit aperture substantially covered by a lens;

a second top wall a planar support member mounted to said second top wall;

said at least one LED mounted on said planar support member, said planar support member positioned adjacent to said second top wall;

said light engine module having at least one first clip extending into said luminaire housing; and

at least one second clip attached to said luminaire housing, said at least one second clip frictionally engaging and separable from said at least one first clip such that a pulling force (P) will separate said at least one first clip and said at least one second clip.

2. The retrofit LED lighting fixture of claim 1 wherein said at least one second clip is removably attachable to said top wall of said luminaire housing.

3. The retrofit LED lighting fixture of claim 2 wherein said at least one second clip engages one or more first top wall apertures of said luminaire housing.

4. The retrofit LED lighting fixture of claim 1 wherein said luminaire housing is longitudinally extending from a first end to a second end creating a substantially rectangular internal cavity.

5. The retrofit LED lighting fixture of claim 1, said junction box having one or more knockouts.

6. The retrofit LED lighting fixture of claim 1, said face plate adjacent said internal cavity of said luminaire housing.

7. The retrofit LED lighting fixture of claim 6, said power supply interposed between said face plate and a junction box wiring cavity.

8. The retrofit LED lighting fixture of claim 1 further comprising a heat dissipating structure attached to an outer surface of said second top wall, said heat dissipating structure including one or more fins extending into said luminaire housing internal cavity.

9. A retrofit LED lighting fixture, comprising:

a luminaire housing having an opening, said luminaire housing having a top wall opposite said opening, said top wall having one or more top wall apertures;

said luminaire housing defining an internal cavity;

said luminaire housing having a first side member having a junction box aperture;

a junction box containing a power supply, said junction box matingly received in said junction box aperture;

said junction box having a removable face plate;

a light engine module within said internal cavity of said luminaire housing, said light engine module having at least one LED;

said light engine module having a light exit aperture;

a planar support member mounted to a second top wall of said light engine module;

said at least one LED mounted on said planar support member; and

said light engine module having one or more spring clips extending into said luminaire housing, said spring clips removably supported in said luminaire housing such that said light engine module may be separated from said luminaire housing by a pulling force (P) in a direction away from said luminaire housing.

10. The retrofit LED lighting fixture of claim 9 wherein said spring clips of said light engine module are removably attachable to said top wall of said luminaire housing.

11. The retrofit LED lighting fixture of claim 10 wherein said spring clips of said light engine module engage said one or more top wall apertures of said top wall of said luminaire housing.

12. The retrofit LED lighting fixture of claim 9 wherein said spring clips include interceding spring clips that attach to said top wall of said luminaire housing.

13. The retrofit LED lighting fixture of claim 9, said removable face plate adjacent said internal cavity.

14. The retrofit LED lighting fixture of claim 9, said face plate having an outer perimeter that is smaller and within an outer perimeter of said junction box aperture of said luminaire housing.

15. The retrofit LED lighting fixture of claim 9, said power supply adjacent said face plate, said power supply interposed between said face plate and a junction box wiring cavity.

16. The retrofit LED lighting fixture of claim 9 further comprising one or more heat dissipating fins extending into said luminaire housing internal cavity.

17. A retrofit LED lighting fixture, comprising:

a luminaire housing having an opening, said luminaire housing having a top wall opposite said opening, said top wall having one or more top wall apertures;

said luminaire housing substantially defining an internal cavity;

said luminaire housing having a first side member having a junction box aperture;

a junction box for receiving external wiring;

a light engine module within said internal cavity of said luminaire housing, said light engine module having at least one LED;

said light engine module having a light exit aperture;

a planar support member mounted to a second top wall of said light engine module;

said at least one LED mounted on said planar support member; and

said light engine module having one or more compressible spring clips extending into said luminaire housing, said spring clips separably attached in said luminaire housing by an interference fit, said spring clips separable from said luminaire housing by a pulling force (P) in a direction away from said luminaire housing.

18. The retrofit LED lighting fixture of claim 17 wherein said compressible spring clips of said light engine module are separably attachable to said top wall of said luminaire housing.

19. The retrofit LED lighting fixture of claim 17 wherein said spring clips of said light engine module engage said one or more top wall apertures of said top wall of said luminaire housing.

20. The retrofit LED lighting fixture of claim 17 wherein said spring clips include interceding spring clips that attach to said top wall of said luminaire housing.
