Abstract

A lighting fixture includes a lighting device, a motion sensor, and a wireless transceiver configured to transmit and receive wireless signals. The lighting fixture further includes a controller communicably coupled to the lighting device, to the motion sensor, and to the transceiver. The controller is configured to adjust a light provided by the lighting device based on a motion detection by the motion sensor and based on a wireless input signal received by the transceiver indicating whether a second motion is detected by a second lighting fixture.

Claims

1. A lighting fixture, comprising:

a lighting device;

a motion sensor;

a transceiver configured to transmit and receive wireless signals; and

a controller communicably coupled to the lighting device, to the motion sensor, and to the transceiver, wherein the controller is configured to adjust a light provided by the lighting device based on a motion detection by the motion sensor and based on a wireless input signal received by the transceiver indicating whether a second motion is detected by a second lighting fixture, wherein the wireless input signal includes an identification string associated with the second lighting fixture, and wherein the wireless input signal is a radiofrequency wireless input signal, and wherein the controller is configured to determine whether the identification string is a valid identification string and to control the lighting device based on the wireless input signal if the identification string is the valid identification string.

2. The lighting fixture of claim 1, wherein the lighting fixture is configured to transmit a wireless output signal indicating the motion detection by the motion sensor.

3. The lighting fixture of claim 2, wherein the wireless output signal includes a second identification string for use by a receiving lighting fixture to determine whether to adjust a light emitted by the receiving lighting fixture based on the wireless output signal.

4. The lighting fixture of claim 1, wherein a power level of the wireless output signal is adjustable based on a user input to increase a number of lighting fixtures that receive the wireless output signal.

5. The lighting fixture of claim 1, wherein a power level of the wireless output signal is adjustable based on a user input to reduce a number of lighting fixtures that receive the wireless output signal.

6. The lighting fixture of claim 1, wherein adjusting the light provided by the lighting device includes turning on the light.

7. The lighting fixture of claim 1, wherein adjusting the light provided by the lighting device includes increasing an intensity level of the light.

8. The lighting fixture of claim 1, wherein the controller is further configured to adjust the light provided by the lighting device based on a Bluetooth Low Energy beacon signal provided by a mobile device.

9. A lighting network, comprising:

a first lighting fixture comprising a motion sensor, the first lighting fixture configured to;

start emitting a first light or change an intensity level of the first light in response to a detection of a motion; and

transmit a wireless signal indicating the detection of the motion by the first lighting fixture, wherein the wireless signal is a radiofrequency wireless signal;

a second lighting fixture located inside a range of the wireless signal, wherein the second lighting fixture is configured to receive the wireless signal transmitted by the first lighting fixture and to start emitting a second light or change an intensity level of the second light based on the wireless signal; and

a third lighting fixture located inside the range of the wireless signal transmitted by the first lighting fixture and wherein the third lighting fixture is configured to receive the wireless signal transmitted by the first lighting fixture and to start emitting a third light or change an intensity level of the third light based on the wireless signal.

10. The lighting network of claim 9, further comprising a third lighting fixture located outside a range of the wireless signal transmitted by the first lighting fixture and inside a range of a second wireless signal transmitted by the second lighting fixture, wherein the second wireless signal indicates a second motion detection by a motion sensor of the second lighting fixture and wherein the third lighting fixture is configured to start emitting a third light or change an intensity level of the third light in response to receiving the second wireless signal.

11. The lighting network of claim 10, wherein the second lighting fixture is configured to determine whether the wireless signal includes a valid identification string before changing the intensity level of the second light in response to receiving the wireless signal.

12. The lighting network of claim 10, wherein the third lighting fixture is configured to determine whether the second wireless signal includes a valid identification string before starting to emit the third light and before changing the intensity level of the third light based on receiving the second wireless signal.

13. The lighting network of claim 9, wherein the range of the wireless signal is adjustable by adjusting a power level of the wireless signal.

14. A method of controlling lighting, the method comprising:

detecting a motion by a motion sensor of a lighting fixture;

receiving an input wireless signal by the lighting fixture;

transmitting, by the lighting fixture, an output wireless signal indicating a detection of the motion by the motion sensor of the lighting fixture, wherein the output wireless signal includes a first identification string associated with the lighting fixture; and

adjusting, by the lighting fixture, a light provided by the lighting fixture based on the detecting of the motion by the motion sensor of the lighting fixture and the input wireless signal, wherein the input wireless signal includes a second identification string associated with a second lighting fixture, and wherein the input wireless signal and the output wireless signal are radiofrequency wireless signals, wherein the lighting fixture adjusts the light provided by the lighting fixture based on the wireless input signal if the second identification string is a valid identification string.

15. The method of claim 14, further comprising adjusting a range of the wireless output signal by adjusting a power level of the wireless output signal.

16. The method of claim 14, further comprising determining whether the input wireless signal includes a valid identification string before adjusting the light provided by the lighting fixture based on the input wireless signal.

17. The method of claim 14, wherein the input wireless signal is a Bluetooth Low Energy beacon signal received from a mobile device.
