Abstract

A recessed lighting system is provided. The recessed lighting system includes a light module and a driver separately coupled to a chassis. The light module includes one or more rotatable prongs for allowing the light module to pivot while the driver and chassis remain static. By being mechanically separate, the driver does not interfere with the movement of the light module. In particular, since the light module is not directly coupled to and is mechanically separate from the driver, pivoting the light module does not require space in a cavity of an associated housing to accommodate the rotation of the driver. This independent freedom of movement allows the light module to achieve a greater degree of rotation in comparison to light modules that are mechanically dependent on drivers.

Claims

1. A pivoting recessed lighting system, comprising:

a light module for emitting light;

a driver for powering the light module to emit light;

a chassis for mounting the light module and the driver, wherein (1) the light module is pivotably coupled to the chassis such that the light module may pivot about an axis and (2) the driver is coupled to the chassis to remain static and mechanically independent from the light module; and

a plurality of rotatable prongs coupled between the light module and the chassis, the rotatable prongs allowing the light module to pivot relative to the chassis and the driver.

2. The pivoting recessed lighting system of claim 1, further comprising:

an outer lip coupled to the chassis, the outer lip including a plurality of slots separated by one or more ridges located on a locking surface of the outer lip.

3. The pivoting recessed lighting system of claim 2, further comprising:

a housing that defines a round cavity to receive the light module, the driver, and the chassis, wherein the housing is configured to be installed within a wall or ceiling of a building; and

a trim coupled to the outer lip for covering a hole in which the lighting system is placed within.

4. The pivoting recessed lighting system of claim 3, wherein the trim comprises:

a plurality of tabs to fit through the plurality of slots and for coupling the trim to the outer lip by engaging the ridges of the outer lip through a twist and lock motion.

5. The pivoting recessed lighting system of claim 3, wherein the chassis comprises:

a driver mount for statically mounting the driver to the chassis; and

a light module mount for mounting the light module.

6. The pivoting recessed lighting system of claim 5, further comprising:

support brackets for coupling the combined chassis, light module, driver, and the trim to the housing.

7. The pivoting recessed lighting system of claim 6, wherein the support brackets are one of a V-spring and a friction clip.

8. The pivoting recessed lighting system of claim 6, wherein the support brackets are located on the outer lip.

9. The pivoting recessed lighting system of claim 6, wherein the support brackets are located on the trim.

10. The pivoting recessed lighting system of claim 1, wherein the light module is a light emitting diode (LED) module and the driver coverts an alternating current (AC) to a direct current (DC) for driving the LED module.

11. The pivoting recessed lighting system of claim 1, further comprising:

a cover to shield the light module while being transmissive to light emitted by the light module.

12. The pivoting recessed lighting system of claim 1, further comprising:

a plurality of fins on one or more sides of the light module for dissipating heat produced by the light module.

13. The pivoting recessed lighting system of claim 1, further comprising:

a cover to shield the light module while being transmissive to light emitted by the light module, wherein the cover is mechanically coupled to the light module such that the cover pivots along with the light module.

14. The pivoting recessed lighting system of claim 13, wherein the cover includes one or more of an integrated lens, a filter, and a reflector for focusing, multiplying, or adjusting light emitted by the light module.

15. A pivoting recessed lighting system, comprising:

a housing that defines a round cavity;

a light module for emitting light, the light module pivotably coupled to a sidewall of the cavity;

a driver for powering the light module to emit light, the driver coupled to the sidewall of the cavity above and mechanically separate from the light module such that the light module may pivot while the driver remains static; and

an outer lip coupled to the light module, the outer lip includes one or more support brackets for coupling the light module to the sidewall of the cavity, wherein the outer lip acts as a gimbal to allow the light module to pivot relative to the housing and the driver.

16. The pivoting recessed lighting system of claim 15, wherein the outer lip further includes a plurality of slots separated by one or more ridges located on a locking surface of the outer lip to receive a trim.

17. A pivoting retrofit recessed lighting system, comprising:

a light chassis, including;

a light module mount for receiving and pivotably coupling with a light module;

a driver mount for receiving and statically coupling with a driver for the light module, wherein (1) the light module is pivotably coupled to the light module mount such that the light module may pivot about an axis and (2) the driver is coupled to the chassis to remain static and mechanically independent from the light module; and

a plurality of rotatable prongs coupled between the light module and the chassis, the rotatable prongs allowing the light module to pivot along a transverse axis relative to the chassis and the driver.

18. The pivoting retrofit recessed lighting system of claim 17, further comprising:

an outer lip coupled to the chassis, the outer lip including a plurality of slots separated by one or more ridges located on a locking surface of the outer lip; and

support brackets coupled to a ridge that is perpendicular to the locking surface, the support brackets for coupling the chassis to a housing.

19. The pivoting retrofit recessed lighting system of claim 18, further comprising:

a trim coupled to the outer lip for covering a hole in which the lighting system is placed within.
