Abstract

A light fixture suitable for use with fluorescent light bulbs as a fluorescent light fixture includes a frame, a plurality of LED mounting strips that are removably coupled to the frame, a plurality of LEDs that are disposed on each of the plurality of LED mounting strips, and a plurality of drivers. Each of the plurality of drivers is disposed on one of the plurality of LED mounting strips and electrically coupled to the plurality of LEDs disposed on each of the plurality of LED mounting strips.

First claim

What is claimed is:

1. A light fixture suitable for use with fluorescent light bulbs as a fluorescent light fixture, the light fixture comprising:
a frame comprising a reflector having a plurality of elongated channels;
a plurality of LED mounting strips removably coupled to the frame, wherein the reflector is configured such that each of the plurality of LED mounting strips is located within one of the plurality of elongated channels when coupled to the frame, and wherein each of the plurality of LED mounting strips is in contact with the reflector;
a plurality of LEDs disposed on each of the plurality of LED mounting strips; and
a plurality of drivers, each of the plurality of drivers disposed on one of the plurality of LED mounting strips and electrically coupled to the plurality of LEDs disposed on each of the plurality of LED mounting strips.

2. The light fixture of claim 1 , further comprising a plurality of lens strips, each of the plurality of lens strips associated with one of the plurality of LED mounting strips and configured to cover a plurality of the plurality of LEDs disposed on each of the plurality of LED mounting strips.

3. The light fixture of claim 1 , wherein the frame and the plurality of LED mounting strips are configured such that each of the plurality of LED mounting strips can be removed from the frame without the use of tools.

4. The light fixture of claim 1 , a plurality of power controllers, each of the plurality of power controllers disposed on, and configured to selectively vary an amount of power applied to, one of the plurality of LED mounting strips;
wherein a total light output intensity and profile of the light fixture can be customized by selectively adjusting one of the plurality of power controllers.

5. The light fixture of claim 4 , wherein each of the plurality of drivers is coupled to one of the plurality of power controllers.

6. The light fixture of claim 4 , wherein each of the plurality of power controllers includes at least three positions corresponding to at least three different lighting intensity levels.

7. The light fixture of claim 4 , further comprising an occupancy sensor coupled to each of the plurality of power controllers;
wherein the occupancy sensor selectively causes at least one of the plurality of power controllers to change states.

8. The light fixture of claim 4 , wherein each of the plurality of LED mounting strips defines opposing end portions;
wherein each of the plurality of drivers is disposed on one of the opposing end portions; and
wherein each of the plurality of power controllers is disposed on one of the opposing end portions.

9. The light fixture of claim 1 , wherein each of the plurality of LED mounting strips defines opposing end portions; and
wherein each of the plurality of drivers is disposed on one of the opposing end portions.

10. A light system comprising:
a frame configured to receive fluorescent light bulbs and to be retrofit with a light fixture, the frame comprising a reflector having an elongated channel, the light fixture comprising:
a LED mounting strip configured to be removably coupled to the frame wherein the reflector is configured such that the LED mounting strip is located within the elongated channel, and wherein the LED mounting strip is in contact with the reflector;
a plurality of LEDs disposed on the LED mounting strip; and
a power control device disposed on the LED mounting strip and configured to selectively vary an amount of power applied to the plurality of LEDs;

wherein a total light output intensity and profile of the light fixture can be customized by selectively adjusting the power control device.

11. The light system of claim 10 , wherein the light fixture further comprises a driver disposed on the LED mounting strip and electrically coupled to the plurality of LEDs and the power control device.

12. The light system of claim 11 , wherein the LED mounting strip defines opposing end portions;
wherein the power control device is disposed on one of the opposing end portions; and
wherein the driver is disposed on one of the opposing end portions.

13. The light system of claim 10 , wherein the light fixture further comprises an occupancy sensor coupled to the power control device; and
wherein detected occupancy causes the power control device to change states.

14. The light system of claim 10 , wherein the light fixture further comprises a lens strip coupled to the LED mounting strip and covering the plurality of LEDs.

15. The light system of claim 10 , wherein the frame and the LED mounting strip are configured such that the LED mounting strip can be installed into, and uninstalled from, the frame without the use of tools.

16. A light system comprising:
a frame configured to receive fluorescent light bulbs and to be retrofit with a light fixture, the frame comprising a reflector having an elongated channel, the light fixture comprising:
a LED mounting strip configured to be removably coupled to the frame wherein the reflector is configured such that the LED mounting strip is located within the elongated channel, and wherein the LED mounting strip is in contact with the reflector;
a plurality of LEDs disposed on the LED mounting strip;
a driver disposed on the LED mounting strip and electrically coupled to the plurality of LEDs; and
a lens strip coupled to the LED mounting strip and covering the plurality of LEDs;

wherein the frame and the LED mounting strip are configured such that the LED mounting strip can be installed into, and uninstalled from, the frame without the use of tools.

17. The light system of claim 16 , wherein the light fixture further comprises a power control device disposed on the LED mounting strip and configured to selectively vary an amount of power applied to the plurality of LEDs;
wherein a total light output intensity and profile of the light fixture can be customized by selectively adjusting the power control device.
