Solid state lighting fixtures with integrated wireless control
View Patent ↗A Solid State Lighting fixture (SSL fixture) for illuminating a desired area, includes 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 and a wireless module integrated with the SSL light engine and used for communicating with a remote controller using a wireless network.
1. A Solid State Lighting fixture (SSL fixture) for illuminating a desired area, comprising:
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 elements comprise a plurality of LED elements arranged in series with regard to a DC power supply voltage;
a sensor communicatively coupled to SSL, the sensor being inactive except for being active for at least one specified time interval set in accordance with the real time clock; and
a wireless module integrated with the SSL light engine and used for communicating with a remote controller using a wireless network, wherein power for the wireless module is provided through at least one voltage regulator receiving power off of a tap between two of the LED elements.
2. The SSL fixture as recited in claim 1 wherein when the SSL elements are dimmed, the wireless module receives power from an auxiliary power source.
3. The SSL fixture as recited in claim 1 , wherein the SSL light engine and the wireless module are arranged on a single printed circuit board.
4. The SSL fixture as recited in claim 1 , wherein the SSL light engine is arranged on a primary circuit board and the wireless module is arranged on a secondary circuit board.
5. The SSL fixture as recited in claim 4 , further comprising:
a battery backup for supplying power to the real time clock during loss of power to the SSL fixture, wherein the real time clock maintains information including date and time information.
6. The SSL fixture as recited in claim 5 , wherein the real time clock and the battery backup are arranged on the secondary circuit board.
7. The SSL fixture as recited in claim 1 , further comprising a housing, wherein the SSL light engine and the wireless module are positioned within the housing for lighting a desired area.
8. The SSL fixture as recited in claim 7 , wherein the sensor further comprises at least one of a photo sensor and a motion sensor.
9. The SSL fixture as recited in claim 8 , wherein the at least one of the photo sensor and the motion sensor are provided within the housing.
10. The SSL fixture as recited in claim 8 , wherein the at least one of the photo sensor and the motion sensor are provided external to the housing and connect to the SSL fixture via at least one interface.
11. A Solid State Lighting fixture (SSL fixture) for illuminating a desired area, comprising:
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 elements comprise a plurality of LED elements arranged in series with regard to a DC power supply voltage;
a sensor communicatively coupled to SSL, the sensor being inactive except for being active for at least one specified time interval set in accordance with the real time clock; and
a wireless module integrated with the SSL light engine and used for communicating with a remote controller using a wireless network, wherein the wireless module controls the SSL fixture in response to commands from the remote controller, and wherein power for the wireless module is provided through at least one voltage regulator receiving power off of a tap between two of the LED elements.
12. The SSL fixture as recited in claim 11 , wherein the remote controller is able to remotely program the SSL fixture to set the time and date schedules via the wireless network.
13. The SSL fixture as recited in claim 11 , wherein the SSL fixture is capable of operating as a repeater, wherein the wireless module retransmits commands received from the remote controller to at least one other SSL fixture via the wireless network.
14. The SSL fixture as recited in claim 13 , wherein when the SSL fixture is operating as a repeater, an acknowledgement acknowledging receipt of the command from that at least one other SSL fixture is forwarded to the remote controller by the SSL fixture operating as the repeater.
15. The SSL fixture as recited in claim 11 , wherein the sensor further comprises at least one of a motion sensor and a photo sensor associated with the SSL fixture, wherein the SSL fixture associated with the at least one of the motion sensor and the photo sensor controls other SSL fixtures based on signals received from the at least one motion and photo sensor.
16. The SSL fixture as recited in claim 15 , wherein the at least one of the motion sensor and the photo sensor is arranged integrally with the associated SSL fixture.
17. The SSL fixture as recited in claim 15 , wherein the at least one of the motion sensor and the photo sensor is arranged remote from the associated SSL fixture.
18. The SSL fixture as recited in claim 11 , wherein a plurality of SSL fixtures can be arranged in a group and wherein the remote controller remotely programs the plurality of SSL fixtures to set the time and date schedules by sending one or more commands to the group via the wireless network.
