Abstract

The present disclosure provides solid state lighting fixtures with wireless, sensor and time based controllers to establish configurations for illuminating the lighting fixtures. More particularly, the present disclosure relates to solid state lighting fixtures having a wireless controller that permits illumination intensity adjustments as well activation timing, and sensors that permit efficient optical control.

Claims

1. An SSL system for illuminating a desired area, comprising:

one or more ceiling mountable SSL fixtures that can be arranged to illuminate a desired area, wherein each ceiling mountable SSL fixture includes an SSL light engine and a wireless module mounted to the SSL light engine for communicating with a controller using a wireless network, wherein the controller stores setting and identification information of each SSL fixture and is capable of sending information to each SSL fixture using the wireless network, wherein the wireless module interfaces with a real time clock for controlling at least in part the illumination of the SSL light engine in accordance with stored settings representing times of day and brightness, and a back-up battery to supply power to the real time clock in the event external power to the real time clock is lost.

2. The SSL system of claim 1 wherein, the wireless module is integrated into the SSL light engine.

3. The SSL system of claim 1, further comprising:

a voltage regulator electrically coupled to the wireless module for providing voltage to the wireless module.

4. The SSL system of claim 1, further comprising:

a dimming output control to selectively dim or brighten the SSL light engine.

5. An SSL fixture for illuminating a desired area, comprising:

a ceiling mountable housing for installation in garages or canopies;

an SSL light engine having a plurality of SSL elements that can be activated or dimmed in response to set time and date schedules to illuminate the desired area, wherein the SSL light engine is positioned within the housing such that the plurality of SSL elements can illuminate the desired area;

a wireless module mounted to the SSL light engine and used for communicating with a controller using a wireless network, wherein the wireless module interfaces with a real time clock for controlling at least in part the illumination of the SSL light engine in accordance with stored settings representing times of day and brightness, and a back-up battery to supply power to the real time clock in the event external power to the real time clock is lost; and

wherein the housing is made of a metal that can transfer heat generated by the SSL light engine to the ambient air.

6. The SSL fixture of claim 5, further comprising:

a voltage regulator electrically coupled to the wireless module for providing voltage to the wireless module.

7. The SSL fixture of claim 5, further comprising:

a dimming output control to selectively dim or brighten the SSL light engine.

8. An SSL fixture for illuminating a desired area, comprising:

a ceiling mountable housing for installation in garages or canopies;

an SSL light engine having a plurality of SSL elements that can be activated and dimmed in response to set time and date schedules to illuminate the desired area, wherein the SSL light engine is positioned within the housing such that the plurality of SSL elements can illuminate the desired area;

a wireless module mounted to the SSL light engine and used for communicating with a controller using a wireless network and wherein the wireless module interfaces with a real time clock for controlling at least in part the illumination of the SSL light engine in accordance with stored settings representing times of day and brightness, and a back-up battery to supply power to the real time clock in the event external power to the real time clock is lost; and

wherein the housing is made of a material that can transfer heat generated by the SSL light engine to the ambient air.

9. The SSL fixture of claim 8, further comprising:

a voltage regulator electrically coupled to the wireless module for providing voltage to the wireless module.

10. The SSL fixture of claim 8, further comprising:

a dimming output control to selectively dim or brighten the SSL light engine.

11. The SSL fixture of claim 8, further comprising:

a sensor communicatively coupled to the wireless module for sensing at least one of light and motion.
