Abstract

A retrofit kit for drop ceiling lighting fixtures and a method of retrofitting drop ceiling lighting fixtures are provided. The retrofit kit includes a pair of adapter brackets configured to be mounted to opposing sides of a drop ceiling fixture, and a door-light assembly configured to be pivotally coupled to one adapter bracket, and to be latched to the other adapter bracket.

Claims (42)

1. A retrofit kit for a drop ceiling lighting fixture having a housing, comprising:

a first adapter bracket configured to be secured to the drop ceiling lighting fixture, wherein the first adapter bracket comprises at least one hinge support;

a second adapter bracket configured to be secured to the drop ceiling lighting fixture, wherein the second adapter bracket comprises at least one latch retainer; and

a door-light assembly having a first side configured to be pivotally secured to the first adapter bracket and a second side configured to be latched to the second adapter bracket, wherein the second side is opposite the first side, wherein and the door-light assembly comprises at least one hinge configured to be coupled to the at least one hinge support, and the door-light assembly comprises at least one latch configured to latch the door-light assembly to the second adapter bracket, and wherein at least one of the first and second adapter brackets have a stop portion configured to align the door-light assembly with the housing of the drop ceiling lighting fixture.

2. The retrofit kit of claim 1 , wherein the latch retainer comprises a tab.

3. The retrofit kit of claim 1 , wherein the first and second adapter brackets each have at least one cutout configured to allow a screw to pass through the cutout to permit fastening the adapter brackets to the housing of a drop ceiling lighting fixture.

4. The retrofit kit of claim 1 , wherein the door-light assembly comprises:

a reflector assembly having:

a first surface for securing at least one hinge to the reflector assembly;

a second surface for securing at least one latch to the reflector assembly; and

at least one light source mounting surface;

at least one solid state lighting source mounted to the at least one light source mounting surface;

control electronics to control power to the at least one solid state lighting source; and

a pair of end plates coupled to the reflector assembly.

5. The retrofit kit of claim 4 , wherein the at least one optical lens is positioned over the at least one solid state lighting source.

6. The retrofit kit of claim 4 , wherein the solid state lighting source comprises an LED module.

7. The retrofit kit of claim 4 , wherein the at least one light source mounting surface is flat.

8. The retrofit kit of claim 4 , wherein the at least one light source mounting surface is pitched.

9. A door-light assembly for retrofitting drop ceiling light fixtures, the door-light assembly comprising:

a reflector assembly having:

a first surface for securing at least one hinge to the reflector assembly;

a second surface for securing at least one latch to the reflector assembly; and

at least one light source mounting surface;

at least one solid state lighting source mounted to the at least one light source mounting surface;

control electronics to control power to the at least one solid state lighting source; and

a pair of end plates coupled to the reflector assembly,

wherein at least one of the first surface and the second surface has a stop portion configured to align the door-light assembly.

10. The door light assembly of claim 9 , wherein at least one optical lens is positioned over the at least one solid state lighting source.

11. The door light assembly of claim 9 , wherein the solid state lighting source comprises an LED module.

12. The door light assembly of claim 9 , wherein the at least one light source mounting surface is flat.

13. The door light assembly of claim 9 , wherein the at least one light source mounting surface is pitched.

14. A method of retrofitting a drop ceiling lighting fixture that can be coupled to an electrical wiring system and positioned within a grid structure, the drop ceiling lighting fixture having a housing for supporting components of the drop ceiling lighting fixture, the method comprising the steps of:

removing at least one of the components within the drop ceiling lighting fixture;

positioning a first adapter bracket along a first side of the housing of the drop ceiling lighting fixture such that a base portion of the first adapter bracket is positioned between the housing of the drop ceiling lighting fixture and the grid structure, wherein the first adapter bracket comprises at least one hinge support;

aligning the first adapter bracket with the housing of the drop ceiling lighting fixture until a stop flange portion of the first adapter bracket is engaged with the housing of the drop ceiling lighting fixture;

fastening the first adapter bracket to the first side of the housing of the drop ceiling lighting fixture;

positioning a second adapter bracket along a second side of the housing of the drop ceiling lighting fixture such that a base portion of the second adapter bracket is positioned between the housing of the drop ceiling lighting fixture and the grid structure wherein the second adapter bracket comprises at least one latch retainer;

aligning the second adapter bracket with the housing of the drop ceiling lighting fixture until a stop flange portion of the second adapter bracket is engaged with the housing of the drop ceiling lighting fixture;

fastening the second adapter bracket to the second side of the housing of the drop ceiling lighting fixture;

coupling a door-light assembly to the first adapter bracket such that the door-light assembly can pivot between a suspended position and a latched position;

connecting the door-light assembly to the electrical wiring system; and

latching the door-light assembly to the second adapter bracket such that the door-light assembly is on the latched position.
