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. A separate 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 selectively adjusting the power control device for each of the mounting strips.

Claims

1. A light fixture, comprising:

a frame;

a plurality of mounting strips disposed on the frame, each mounting strip having a quick-disconnect connector;

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

a power control device associated with the mounting strips, wherein the power control device is configured to selectively vary an amount of power applied to the mounting strips, and wherein a total light output intensity and profile of the fixture can be customized by selectively adjusting the power control device for the mounting strips and by changing the mounting strips using the quick-disconnect connector;

wherein the mounting strips further comprise an intermediate portion and opposite end portions;

wherein at least one of the end portions includes the quick-disconnect connector and includes a replaceable LED driver;

wherein the opposite end portions are fixed to the light fixture; and

wherein the intermediate portion is removably disposed on the frame.

2. The light fixture of claim 1, wherein at least one of the end portions includes the quick-disconnect connector and includes the replaceable LED driver, and wherein the quick-disconnect connector electrically couples the intermediate portion to the replaceable LED driver.

3. The light fixture of claim 2, wherein the replaceable LED driver is coupled to the power control device.

4. 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.

5. The light fixture of claim 1, wherein the power control device associated with the mounting strips includes at least three positions corresponding to at least three different lighting intensity levels.

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

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

7. A method comprising:

providing a preassembled light fixture comprising an open frame and a plurality of mounting strips, a plurality of LEDs mounted on each of the lighting strips, and a power control device associated with the mounting strips, wherein the power control device is configured to selectively vary an amount of power applied to the mounting strips; and

changing the total light output intensity and profile of the light fixture by selectively adjusting the power control device for each of the mounting strips;

wherein each of the plurality of mounting strips includes an intermediate portion and opposite end portions;

wherein the opposite end portions are fixed to the preassembled light fixture; and

wherein the intermediate portion is removably disposed on the open frame.

8. The method of claim 7, further comprising:

selectively interchanging a mounting strip on the open frame with a different mounting strip utilizing a quick-disconnect connector of the mounting strip,

wherein the quick-disconnect connector connects the mounting strip to the power control device,

wherein the mounting strips include at least one end portion having the quick-disconnect connector, and

wherein the different mounting strip has at least one of LEDs with different light emitting properties or different lenses associated with the LEDs.

9. The method of claim 7, wherein selectively adjusting the power control device comprises setting at least two mounting strips to one of at least three different lighting levels.

10. The method of claim 9, further comprising:

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

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

11. A light fixture, comprising:

an open 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;

a first quick-disconnect connector releasably coupling a driver to a power source; and

a second quick-disconnect connector releasably coupling the mounting strip and the driver, the second quick-disconnect connector configured to provide power from the driver, which is received from the power source via the first quick-disconnect connector, to the mounting strip,

wherein the total light output intensity and profile of the fixture can be customized;

wherein the first quick-disconnect connector and the second quick-disconnect connector cooperatively facilitate replacing the driver without requiring the removal of the mounting strip;

wherein the light fixture is configured to allow for the removal of the mounting strip using the second quick-disconnect connector;

wherein the light fixture is configured to accept a different mounting strip having different light properties using the second quick-disconnect connector;

wherein the mounting strip includes an intermediate portion and opposite end portions;

wherein the opposite end portions are fixed to the light fixture; and

wherein the intermediate portion is removably disposed on the open frame.

12. The light fixture of claim 11, wherein the driver is mounted to one of the opposite end portions of the mounting strip using a tool-less connector which allows for tool-less replacement of the driver.

13. The light fixture of claim 11, further comprising at least one power control device coupled to the driver.

14. The light fixture of claim 13, further comprising processing electronics configured to change a setting of the power control devices in response to a signal received from at least one of communications electronics and a motion sensor.

15. The light fixture of claim 13, wherein the power control device controls light output for a plurality of mounting strips including a plurality of LEDs.

16. The light fixture of claim 13, wherein the power control device controls light output for a single mounting strip and plurality of LEDs on the mounting strip.

17. The light fixture of claim 11, wherein the open 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.
