Abstract

A lighting fixture having a light source, a light sensor, a communication interface, and circuitry is described. In addition to controlling the light source, the circuitry is adapted to monitor for a light signal provided from a handheld device via the light sensor; upon receiving the light signal, measure a signal level associated with the light signal; and effect transmission of the signal level to the handheld device via the communication interface. In one embodiment, the circuitry is further configured to receive an instruction to monitor for the light signal from the handheld device via the communication interface such that the circuitry begins monitoring for the light signal upon receiving the instruction.

Claims

1. A switch module for controlling at least one lighting fixture in a lighting network comprising:

a user interface configured to receive input from a user;

a communication interface configured to communicate with the at least one lighting fixture; and

circuitry configured to;

receive a first instruction from a handheld device via the communication interface to monitor for a switch selection input to be received from the user via the user interface;

monitor for the switch selection input;

upon receiving the switch selection input, provide an identifier for the switch module to the handheld device; and

provide lighting control information to the at least one lighting fixture via the communication interface, the lighting control information configured to control light output levels of the at least one lighting fixture.

2. The switch module of claim 1 wherein the identifier is an address for the switch module.

3. The switch module of claim 1 wherein the communication interface is a wireless communication interface.

4. The switch module of claim 1 further comprising a light source, and wherein the circuitry is further configured to drive the light source to provide visible feedback to the user that the switch module has been selected from the handheld device.

5. The switch module of claim 4 wherein the circuitry is further configured to receive a second instruction from the handheld device via the communication interface to provide the visible feedback, such that the circuitry drives the light source to provide the visible feedback upon receiving the second instruction.

6. The switch module of claim 5 wherein the circuitry is further configured to receive a third instruction from the handheld device via the communication interface to stop providing the visible feedback, such that the circuitry stops driving the light source to provide the visible feedback upon receiving the third instruction.

7. The switch module of claim 4 wherein, when driven to provide the visible feedback, the light source is pulsed on and off.

8. The switch module of claim 1 wherein the circuitry is further configured to receive group information from the handheld device via the communication interface, the group information associating the switch module with the at least one lighting fixture.

9. The switch module of claim 1 wherein the circuitry is further configured to receive group information from the handheld device via the communication interface, the group information associating the switch module with a plurality of lighting fixtures, including the at least one lighting fixture, and at least one other switch module.

10. The switch module of claim 1 wherein the lighting control information is determined based on lighting control input that is received from the user via the user interface.

11. The switch module of claim 1 further comprising an ambient light sensor, wherein the lighting control information is a function of an output of the ambient light sensor.

12. The switch module of claim 1 further comprising an occupancy sensor, wherein the lighting control information is a function of an output of the occupancy sensor.

13. The switch module of claim 1 further comprising a sensor and wherein the lighting control information is determined based on either lighting control input that is received from the user via the user interface or an output of the sensor.
