Abstract

A recessed lighting fixture includes a lamp housing and a separate compact junction box, which contains a power supply that drives the lamp and serves in part to divide the interior cavity of the junction box into two separate wiring compartments. The junction box has two end walls spaced along an axis and a releasably secured. The lighting fixture is particularly suitable for retrofit installations, especially where small aperture downlights are desired.

First claim

What is claimed is:

1. A lighting fixture comprising:
a lamp assembly;
a reflector for directing light from the lamp assembly;
a housing having a moveable cover, a first compartment, and a second compartment;
a power supply positioned in said housing; and
a conduit receiving a conductor for delivering power from the power supply to the lamp assembly.

2. A lighting fixture assembly of claim 1 , wherein
the lamp assembly includes an LED light module.

3. A lighting fixture according to claim 1 , wherein
said power supply occupies a portion of each of said first and second compartments.

4. A lighting fixture according to claim 1 , wherein
said first compartment is an input compartment and said second compartment is an output compartment.

5. A lighting fixture according to claim 1 , wherein
said conduit includes a flexible material.

6. A lighting fixture according to claim 5 , wherein
said conduit includes metal.

7. A lighting fixture according to claim 1 , wherein
said power supply includes a driver.

8. A lighting fixture according to claim 1 , wherein
said housing includes a chassis having an aperture for receiving said power supply.

9. A lighting fixture comprising:
a lamp assembly including a lamp housing;
a junction box assembly having a moveable cover, an input for a first conductor carrying power at a first voltage and an output for a second conductor carry power at a second voltage less than said first voltage;
a power supply positioned in said junction box assembly for converting power from said first voltage to said second voltage; and
a movable conduit receiving said second conductor and delivering power from the power supply to the lamp assembly.

10. A lighting fixture assembly of claim 9 , wherein
the lamp assembly includes an LED light module.

11. A lighting fixture according to claim 9 , wherein
said power supply includes a driver.

12. A lighting fixture according to claim 9 , wherein
the lamp assembly includes a heat sink.

13. A lighting fixture according to claim 9 , wherein
a chassis separates the junction box into a first compartment and a second compartment.

14. A lighting fixture according to claim 13 , wherein
said power supply is connected to said chassis and occupies a portion of each of said first and second compartments.

15. A lighting fixture according to claim 14 , wherein
said chassis includes an aperture receiving said power supply.

16. A lighting fixture comprising:
a lamp assembly including a lamp housing having a first maximum width;
a junction box assembly having a moveable cover, an inlet for a high voltage power input, and an outlet for a low voltage power output, the junction box assembly having a second maximum width no greater than the first maximum width;
a power supply positioned in said junction box assembly; and
a conduit connected to said lamp assembly and connected to said junction box assembly.

17. A lighting fixture of claim 16 , wherein
said lamp assembly includes a reflector and a heat skink.

18. A lighting fixture of claim 16 , wherein
said conduit is a flexible conduit.

19. A lighting fixture according to claim 16 , wherein
a chassis separates the junction box into a first compartment and a second compartment.

20. A lighting fixture according to claim 19 , wherein
said chassis includes an aperture receiving said power supply.
