    Abstract: A handheld device for merging groups of lighting fixtures is disclosed. The handheld device includes a communication interface configured to wirelessly communicate with a plurality of lighting fixtures and control circuitry. In one embodiment, the control circuitry is configured to effect selection of a first lighting fixture or a first switch module that is grouped with a first group of lighting fixtures via the communication interface; identify the first group of lighting fixtures; effect selection of a device-to-be-added that is not initially associated with the first group of lighting fixtures via the communication interface; determine a new group by adding the device-to-be-added to the first group of lighting fixtures; create group assignment information for the new group; and send the group assignment information to each of the first group of lighting fixtures and the device-to-be-added of the new group via the communication interface.

    Abstract: Ambient light sensor circuitry includes a photodetector, a controllable current source, and control circuitry. The photodetector is coupled between a supply voltage and an intermediate node and configured to provide a photodetector current proportional to an amount of light detected thereby to the intermediate node. The controllable current source is coupled between the intermediate node and ground and configured to shunt a portion of the photodetector current from the intermediate node to ground based on a current control signal. The control circuitry is coupled to the intermediate node and the controllable current source and configured to provide the current control signal to the controllable current source, receive a measurement signal from the intermediate node, adjust the current control signal such that the measurement signal does not exceed a maximum input threshold of the control circuitry, and provide an ambient light measurement signal based on the current control signal.

    Abstract: Control of lighting fixtures in a lighting network may be distributed among the lighting fixtures. The lighting fixtures may be broken into groups that are associated with different lighting zones. At least some of the lighting fixtures will have or be associated with one or more sensors. Within the overall lighting network or the various lighting zones, the lighting fixtures may share sensor data from their sensors. Each lighting fixture may process sensor data provided by its own sensor, a remote standalone sensor, or lighting fixture, and process the sensor data according to the lighting fixture's own internal logic to control operation of the lighting fixture. The lighting fixtures may also receive control input from other lighting fixtures, control nodes, light switches, and commissioning tools. The control input may be processed along with the sensor data according to the internal logic to further enhance control of the lighting fixture.

    Abstract: A lighting fixture employing a solid-state light source and an ambient light sensor is disclosed. The solid-state light source is placed within a light source housing and configured to emit light through a lens assembly that covers an opening into a mixing chamber provided within the light source housing. In one embodiment, the ambient light sensor is located within mixing chamber with the solid-state light source. In another embodiment, the ambient light sensor is located outside of the mixing chamber. In either embodiment, the ambient light sensor may be recessed within a waveguide, which aides in controlling the sensor distribution beam for the ambient light sensor. The sensor distribution beam essentially defines an area from which light reflected off of a task surface is accurately monitored via the ambient light sensor. The direction of the sensor distribution beam and the light emitted from the ambient light sensor may generally coincide.

    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.
