Abstract

A retrofit light fixture for retrofitting an existing strip-style light fixture includes a housing, a light emitting diode, a driver, and a bracket. The housing includes a top portion, a side portion, and an end cap, and the housing defines an interior space. At least one of the top portion and the side portion define an elongated opening. The bracket includes a locking flange configured to selectively engage with a portion of a housing of the existing strip-style light fixture. The bracket is slidably coupled to the housing with a fastener that extends through the elongated opening. The bracket is selectively repositionable between a disengaged orientation and an engaged orientation, and the bracket is configured to interface with a portion of the existing strip-style light fixture and thereby secure the retrofit light fixture in place when selectively repositioned into the disengaged orientation.

First claim

What is claimed is:

1. A retrofit light fixture for retrofitting an existing strip-style light fixture, the retrofit light fixture comprising:
a housing including a top portion, a side portion, and an end cap, the housing defining an interior space, wherein at least one of the top portion and the side portion define an elongated opening;
a light emitting diode coupled to the top portion of the housing;
a driver disposed within the interior space of the housing and configured to interface with the light emitting diode; and
a bracket including a body and a locking flange, the locking flange configured to selectively engage with a portion of a housing of the existing strip-style light fixture, wherein the bracket is slidably coupled to the housing with a fastener that extends through the elongated opening,
wherein the bracket is selectively repositionable between a disengaged orientation and an engaged orientation, the bracket configured to interface with a portion of the existing strip-style light fixture and thereby secure the retrofit light fixture in place when selectively repositioned into the engaged orientation;
wherein the bracket includes a first portion, a second portion coupled to the first portion, a third portion coupled to the second portion, and a fourth portion coupled to the third portion; and
wherein the first portion extends downward and away from the body, wherein the second portion extends upward and away from the first portion, wherein the third portion extends downward and away from the second portion, and wherein the fourth portion extends upward and away from the third portion.

2. The retrofit light fixture of claim 1 , wherein the first portion is angularly offset from a sidewall of the bracket and extends from an edge thereof, wherein the second portion is angularly offset from the first portion and extends from an edge thereof, wherein the third portion is angularly offset from the second portion and extends from an edge thereof, and wherein the fourth portion is angularly offset from the third portion and extends from an edge thereof.

3. The retrofit light fixture of claim 2 , wherein the fourth portion is chamfered.

4. The retrofit light fixture of claim 1 , wherein the fastener comprises at least one of a peg and a set screw positioned to selectively force the bracket into engagement with the housing and thereby hold the bracket in place when tightened.

5. The retrofit light fixture of claim 1 , wherein the bracket is actuatable from the exterior of the housing by applying force to the fastener without the use of a tool, and wherein the bracket is selectively repositionable without removing a fastener.

6. The retrofit light fixture of claim 1 , further comprising a lens secured to the housing, wherein the lens extends along the length of the retrofit light fixture.

7. The retrofit light fixture of claim 1 , further comprising an individual lens for the light emitting diode.

8. The retrofit light fixture of claim 1 , further comprising a light emitting diode strip, wherein the light emitting diode is disposed on the light emitting diode strip.

9. A retrofit light fixture for retrofitting an existing strip-style light fixture, the retrofit light fixture comprising:
a housing;
a light source coupled to the housing; and
a bracket slidably coupled to the housing and configured to selectively engage with a portion of the existing strip-style light fixture;
wherein the bracket includes a body, a first portion, a second portion, a third portion, and a fourth portion, wherein the first portion is angled downward from the body, wherein the second portion is angled upward from the first portion, wherein the third portion is angled downward from the second portion, and wherein the fourth portion is angled upward from the third portion.

10. The retrofit light fixture of claim 9 , wherein a top portion of the housing defines a slot, wherein the bracket is slidably coupled to the housing with a fastener that extends through the slot, and wherein the bracket is selectively repositionable from below the retrofit light fixture.

11. The retrofit light fixture of claim 9 , wherein a side portion of the housing defines a slot, wherein the bracket is slidably coupled to the housing with a fastener that extends through the slot, and wherein the bracket is selectively repositionable from alongside the retrofit light fixture.

12. The retrofit light fixture of claim 9 , wherein the light source comprises at least one of a plurality of light emitting diodes, an incandescent lamp, and a fluorescent lamp.

13. A method for retrofitting an existing strip-style light fixture with a retrofit light fixture, the method comprising:
repositioning at least one component of the existing strip-style light fixture;
placing the retrofit light fixture around the existing strip-style light fixture, wherein a housing of the retrofit light fixture at least partially surrounds a housing of the existing strip-style light fixture; and
actuating a sliding bracket of the retrofit light fixture into a locked position, wherein the sliding bracket includes a body, a first portion, a second portion coupled to the first portion, a third portion coupled to the second portion, and a fourth portion coupled to the third portion, wherein the first portion extends downward and away from the body, wherein the second portion extends upward and away from the first portion, wherein the third portion extends downward and away from the second portion, and wherein the fourth portion extends upward and away from the third portion, and wherein at least one of the first portion, the second portion, the third portion, and the fourth portion of the sliding bracket engages with a portion of the housing of the existing strip-style light fixture to secure the retrofit light fixture to the existing strip-style light fixture.

14. The method of claim 13 , wherein repositioning at least one component of the existing strip-style light fixture includes removing one or more components of the existing strip-style light fixture.

15. The method of claim 14 , further comprising disconnecting a power source from the existing strip-style light fixture and wiring the retrofit light fixture to the power source.
