Abstract

Present embodiments provide a light fixture having rotatable light modules and an extendable hinged mounting assembly. The light modules are electrically coupled to the light fixture via a cord and a grommet/bracket feature which provides strain relief and a waterproof barrier. The extendable hinged mounting assembly allows the light fixture to be mounted onto a ceiling or other structure while providing a mounted position and an install position.

First claim

What is claimed is:

1. A light fixture comprising:
a central housing containing one or more electrical components;
a central grommet, wherein the central grommet traverses a central opening in the central housing, providing a path for a central cord to enter the central housing through the central grommet, wherein the central grommet forms a water tight seal between the central cord and the central housing, and wherein the central cord is electrically coupled to the one or more electrical components;
at least one rotatable light module coupled to the central housing, the at least one rotatable light module comprising a heat sink on a back side of the at least one rotatable light module, wherein the heat sink comprises a first set of heat sink fins and a second set of heat sink fins, the first set of heat sink fins are separated from the second set of heat sink fins by a space;
at least one bracket assembly comprising a first bracket and a second bracket coupled together by at least one fastener, the at least one bracket assembly is disposed on the heat sink and positioned in the space that separates the first set of heat sink fins from the second set of heat sink fins,
wherein each of the first and second brackets comprises:
a first elongated portion; and
a first leg portion and a second leg portion each extending from the first elongated portion such that the bracket has a C shaped profile,
wherein the first leg portion and the second leg portion of each bracket is disposed on the heat sink, and wherein the first elongated portion of each bracket includes at least one aperture for receiving the at least one fastener; and

at least one peripheral cord coupled to the at least one rotatable light module and traversing the at least one bracket assembly at a first end of the at least one peripheral cord and traversing at least one respective peripheral opening in a side surface of the central housing at a second end of the at least one peripheral cord.

2. The light fixture of claim 1 , further comprising:
at least one peripheral grommet traversing the at least one respective peripheral opening, wherein the at least one peripheral grommet surrounds a portion of the at least one peripheral cord and forms a water tight seal between the portion of the at least one peripheral cord and the central housing.

3. The light fixture of claim 1 , wherein the at least one bracket assembly is disposed at a junction of the at least one peripheral cord and the at least one rotatable light module, wherein the bracket assembly is coupled to the at least one rotatable light module and surrounds a portion of the at least one peripheral cord, holding the portion of the at least one peripheral cord stationary with respect to the at least one rotatable light module.

4. The light fixture of claim 3 , wherein the first bracket and the second bracket of the at least one bracket assembly are coupled to each other by the at least one fastener such that at least a portion of a surface of both the first bracket and second bracket surrounds the cord.

5. The light fixture of claim 3 , wherein the at least one bracket assembly is coupled to the heat sink via a mating feature so that the bracket assembly is stationary with respect to the heat sink.

6. The light fixture of claim 5 , wherein the at least one bracket assembly includes at least one slot that engages with at least one protrusion of the heat sink.

7. The light fixture of claim 1 , wherein the central housing comprises two or more corner sections disposed at respective corners of the central housing, wherein the at least one rotatable light module is disposed near at least one edge of the central housing between two of the two or more corner sections, wherein the at least one rotatable light module is coupled to the two corner sections such that the rotatable light module is rotatable with respect to the two corner sections.

8. The light fixture of claim 7 , wherein the two or more corner sections each comprise a locking mechanism, the locking mechanism configured to lock the at least one rotatable light module in a plurality of positions.

9. The light fixture of claim 1 , further comprising:
a mounting mechanism coupled to the central housing at a first portion and configured to couple to a support structure at a second portion, wherein the first portion and the second portion are coupled by a movable middle portion, wherein the light fixture is movable between a hanging position and a mounted position via the mounting mechanism.

10. The light fixture of claim 1 , wherein the central housing is made of a deep drawn process using cold rolled steel.

11. A light fixture comprising:
a central housing containing one or more electrical components;
a grommet, wherein the grommet traverses an opening in the central housing, providing a path for a cord to enter the central housing through the grommet, wherein the grommet forms a water tight seal between the cord and the central housing;
at least one rotatable light module coupled to the central housing, the at least one rotatable light module comprising a heat sink on a heat sink side of the at least one rotatable light module,
wherein the heat sink comprises a first set of heat sink fins and a second set of heat sink fins, the first set of heat sink fins are separated from the second set of heat sink fins by a space, and
wherein at least one heat sink fin of the first set of heat sink fins and/or the second set of heat sink fins comprises a protrusion that is integral with the at least one heat sink fin and extends substantially perpendicularly to at least one heat sink fin;

at least one peripheral wire coupled to the at least one rotatable light module at a first end of the at least one peripheral wire and the one or more electrical components at an opposite end of the at least one peripheral wire, wherein the at least one peripheral wire electrically couples the one or more electrical components and the rotatable light module; and
at least one bracket assembly coupled to the at least one rotatable light module and configured to provide a path for the at least one peripheral wire to the at least one rotatable light module,
wherein the at least one bracket assembly is disposed on the heat sink and positioned in the space that separates the first set of heat sink fins from the second set of heat sink fins, and
wherein the at least one bracket assembly includes a notch that is adapted to engage the protrusion integral with the at least one heat sink fin to provide protection and support for a connection of the at least one peripheral wire to the at least one rotatable light module during rotation of the at least one rotatable light module.

12. The light fixture of claim 11 , wherein the central housing comprises two or more corner sections disposed at respective corners of the central housing, wherein the at least one rotatable light module is disposed near at least one edge of the central housing between two of the two or more corner sections, wherein the at least one rotatable light module is coupled to the two corner sections such that the rotatable light module can rotate with respect to the two corner sections.

13. The light fixture of claim 11 , further comprising:
four rotatable light modules disposed at four respective sides of the central housing, each of the four rotatable light modules comprising a respective heat sink.
