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 light fixture, comprising:

a frame;

a plurality of mounting strips removably disposed on the frame;

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

a plurality of interchangeable lenses disposed over the LEDs and removably coupled to the mounting strip; 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 on the frame, and selectively adjusting the multi-position power control device for each of the mounting strips.

2. The light fixture of claim 1, further comprising:

a connector near each LED location on each mounting strip, the connector providing for quick interchangeability of lenses.

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

4. The light fixture of claim 3, wherein the plurality of interchangeable lenses includes a first lens having a first degree of curvature and a second lens having a second degree of curvature.

5. The light fixture of claim 3, wherein the plurality of interchangeable lenses includes a first lens having a first degree of length and curvature and a second lens having a second degree of length and curvature.

6. The light fixture of claim 3, wherein the plurality of interchangeable lenses includes a lens having an open middle portion and a dished outer portion.

7. The light fixture of claim 1, wherein the frame comprises a reflector having a plurality of elongated channels, wherein the elongated channels include a first angled sidewall, a second angled sidewall, and a flat upper wall, wherein the mounting strips are coupled to the flat upper walls of the plurality of elongated channels.

8. The light fixture of claim 1, wherein the multi-position power control device for each mounting strip includes at least three positions corresponding to at least three different lighting intensity levels.

9. The light fixture of claim 1, wherein the mounting strips further comprise an intermediate position and opposite end positions, wherein at least one of the end portions comprises a quick-disconnect connector and includes an LED driver.

10. The light fixture of claim 1, further comprising:

a radio frequency communication device coupled to the multi-position power control device, wherein the radio frequency communication device is configured to communicate an operating status of the fixture via radio frequency communications to a remote device.

11. The light fixture of claim 1, further comprising:

a motion sensor coupled to the multi-position power control device, wherein detected motion causes the multi-position power control device to change states.

12. A method comprising:

providing a preassembled light fixture comprising a frame and a plurality of mounting strips, a plurality of LEDs mounted on each of the lighting strips, a plurality of interchangeable lenses disposed over the LEDs and removably coupled to the mounting strips, and a multi-position power control device for each of the mounting strips; and

changing the total light output intensity and profile of the light fixture by;

interchanging lenses on the mounting strips using a connector providing for quick interchangeability of lenses,

interchanging mounting strips on the frame, and

selectively adjusting the multi-position power control device for each of the mounting strips.

13. The method of claim 12, wherein the mounting strips include at least one end portion having a quick-disconnect connector and wherein selectively interchanging mounting a strip on the frame comprises utilizing the quick-disconnect connector of the mounting strip.

14. The method of claim 12, wherein selectively adjusting the multi-position power control device comprises setting at least two mounting strips to one of at least three different lighting levels.

15. The method of claim 14, further comprising:

receiving an indication of motion near the lighting fixture from a motion sensor;

changing at least one of the different lighting levels in response to the received indication.

16. A light fixture, comprising:

a frame supporting a plurality of elongated reflective channels;

a mounting strip disposed within at least one of the elongated reflective channels;

a plurality of LEDs on the mounting strip; and

a quick-disconnect power connector coupled to the mounting strip and configured to provide power from a power source to the mounting strip.

17. The light fixture of claim 16, wherein the mounting strip further comprises an intermediate portion and opposite end portions, wherein the quick-disconnect power connector is coupled to at least one of the end portions.

18. The light fixture of claim 16, wherein the frame comprises a reflector having a plurality of elongated channels, wherein the elongated channels include a first angled sidewall, a second angled sidewall, and a flat upper wall, wherein the mounting strips are coupled to the flat upper walls of the plurality of elongated channels.

19. The light fixture of claim 16, further comprising:

a multi-setting 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 on the frame, and selectively adjusting the multi-setting power control device for each of the mounting strips.

20. The light fixture of claim 19, further comprising processing electronics configured to change a setting of the multi-setting power control devices in response to a signal received from at least one of communications electronics and a motion sensor.
