Abstract

A lighting and energy conservation system for low temperature applications includes LEDs as a light source. The LEDs are provided in a modular LED light fixture. The fixture includes a frame supporting a reflector having a plurality of elongated channels. Mounting strips are removably installed in each of the elongated channels, and LEDs are mounted on each of the mounting strips. Interchangeable lenses are provided over the LEDs and are removably coupled to the mounting strip by a quick-connect device. A separate multi-position power control device is associated with each of the mounting strips, so that a total light output intensity and profile of the fixture can be individually customized by any one or more of: interchanging lenses on the LEDs, interchanging mounting strips within the elongated channels, and selectively adjusting the multi-position power control device for each of the mounting strips.

Claims

1. A lighting and energy conservation system for a low-temperature application, comprising:

a modular LED light fixture configured for installation in the low temperature application, the fixture comprising;

a frame supporting a reflector having a plurality of elongated channels;

a plurality of mounting strips, at least one of the mounting strips removably disposed within each of the elongated channels;

a plurality of LEDs mounted on each of the mounting strips;

a plurality of interchangeable lenses disposed over the LEDs and removably coupled to the mounting strip by a quick-connect device; and

a separate multi-position power control device associated with each of the mounting strips, so that a total light output intensity and profile of the fixture can be individually customized by any one or more of;

interchanging lenses on the LEDs, interchanging mounting strips within the elongated channels, and selectively adjusting the multi-position power control device for each of the mounting strips.

2. The system of claim 1 wherein the quick-connect device comprises a twist-lock device having one or more projections extending from the mounting strip that are configured to engage one or more corresponding recesses on the lenses.

3. The system of claim 1 wherein the plurality of lenses provide a plurality of optics having different light dispersal profiles.

4. A lighting and energy conservation system for a low-temperature application, comprising:

a modular LED light fixture configured for installation in the low temperature application, the fixture comprising;

a frame supporting a reflector having a plurality of elongated channels;

a plurality of mounting strips, at least one of the mounting strips removably disposed within each of the elongated channels;

a plurality of LEDs mounted on each of the mounting strips;

a plurality of interchangeable lenses disposed over the LEDs and removably coupled to the mounting strip by a quick-connect device; and

a separate multi-position power control device associated with each of the mounting strips, so that a total light output intensity and profile of the fixture can be individually customized by any one or more of;

interchanging lenses on the LEDs, interchanging mounting strips within the elongated channels, and selectively adjusting the multi-position power control device for each of the mounting strips,

wherein the multi-position power control device comprises a control switch having four positions.

5. The system of claim 4 wherein a first of the four positions corresponds to a maximum light output.

6. The system of claim 5 wherein a second of the four positions corresponds to a light output of approximately 85 percent of the maximum light output.

7. The system of claim 6 wherein a third of the four positions corresponds to a light output of approximately 70 percent of the maximum light output.

8. The system of claim 7 wherein a fourth of the four positions is configured to correspond to a light output that is selectively established by a user of the fixture.

9. A lighting and energy conservation system for a low-temperature application, comprising:

a modular LED light fixture configured for installation in the low temperature application, the fixture comprising;

a frame supporting a plurality of elongated reflective channels;

a plurality of mounting strips removably disposed within each of the elongated reflective channels;

a plurality of LEDs mounted on the mounting strips;

a plurality of interchangeable lenses disposed over the LEDs and removably coupled to the mounting strip by a quick-connect device; and

a separate multi-position power control device associated with the mounting strips, so that a total light output intensity and profile of the fixture can be individually customized by any one or more of;

interchanging lenses on the LEDs, interchanging mounting strips within the elongated channels, and selectively adjusting the multi-position power control device for each of the mounting strips.

10. The system of claim 9 wherein the quick-connect device comprises at least one of a twist-lock device, a slide-lock device and a snap-fit device.

11. The system of claim 9 wherein the plurality of lenses provide a plurality of optics having different light dispersal profiles.

12. The system of claim 9 wherein the mounting strips further comprise an intermediate portion and opposite end portions, wherein at least one of the end portions is coupled to the intermediate portion by a quick-disconnect connector and includes an LED driver.

13. The system of claim 12 wherein the at least one of the end portions further includes a quick-disconnect power connector configured to connect to a power supply.

14. The system of claim 13 wherein both end portions comprise the LED driver and quick-disconnect connector and quick-disconnect power connector.

15. The system claim 9 wherein the multi-position power control device comprises a control switch having four positions.

16. The system claim 15 wherein a first of the four positions corresponds to a maximum light output.

17. The system claim 16 wherein a second of the four positions corresponds to a light output of approximately 85 percent of the maximum light output.
