A lighting system for areal illumination is disclosed which includes a remote driver and a plurality of fixtures including luminaires, control devices, and/or standalone sensors. The luminaires include a light source whose output light level can be adjusted, a light sensor co-located therewith adapted to measure light received from adjacent fixtures, and a microcontroller capable of transmitting the output of the light sensor over wires to the remote driver. The remote driver is capable of bidirectional communication with the luminaires and provides independently controllable power for the light sources of the luminaires. A movable orb region containing luminaires can also be defined and the light levels of individual luminaires can be set according to their location within the orb region.

The remote driver is capable of bidirectional communication with the luminaires and provides independently controllable power for the light sources of the luminaires. A method of commissioning a lighting system is also disclosed which includes installing a plurality of luminaires above the area to be illuminated, causing a light source co-located with each luminaire to emit a signal, detecting the signal at light sensors co-located with each luminaire, converting the signals obtained by the light sensors into distance measurements between luminaires, creating a map recording the relative location of luminaires, and assigning luminaires to groups based on their relative locations in the map. A movable orb region large enough to containing a plurality of luminaires can also be defined and the light levels of individual luminaires can be set according to a defined mathematical function of their location within the orb region, where the defined mathematical function sets light levels which vary from the center to the periphery of said orb region.

Systems and methods for transmitting and processing interrupts by embedding interrupt information into a serial data stream are disclosed. An event is detected and converted into an interrupt signal. The interrupt signal is converted into a special interrupt character or symbol sequence. The special interrupt character or symbol sequence is embedded into a serial data stream at the next available character or symbol boundary and transmitted to a receiving controller. The receiving controller strips the special interrupt character or symbol sequence from the serial data stream and raises a corresponding interrupt. The receiving controller processes the interrupt by interrupting normal processing to run an interrupt subroutine. Once the receiver has detected and raised an interrupt, it can return an acknowledgement character or symbol sequence by the same mechanism. The transmitter can repeat the interrupt embedding and transmission if it fails to receive the acknowledgement within a predetermined period of time.

A system may be provided for controlling an amount of light generated by multiple fluorescent lamps based on a desired light level. A dimming circuit may vary the amount of light generated by at least one of the fluorescent lamps based on the desired light level if the desired light level is in a first range of light level values. The fluorescent lamps remain lit as the amount of light generated by the lamps is varied. A switch circuit may switch off a first subset of the fluorescent lamps while a second subset of the fluorescent lamps remains lit if the desired light level is in a second range of light level values. The second range of light level values indicates less light is desired than the first range of light level values indicates.

Commissioning a lighting system is disclosed. A user can be provided with a pointing device capable of emitting or returning a signal which can be received by detectors co-located with each fixture in the lighting system. The user can add a fixture to a group by aiming the pointing device at the fixture when the fixture is not assigned to the group, and the user can remove a fixture from a group in the same way when the fixture was previously assigned to the group. Additional user gestures are also disclosed.

A user is provided with a pointing device capable of emitting or returning a signal which can be received by detectors co-located with each fixture in the lighting system. The user can add a fixture to a group by aiming the pointing device at the fixture when the fixture is not assigned to the group, and the user can remove a fixture from a group in the same way when the fixture was previously assigned to the group. This commissioning method can be used with a lighting system comprising a central control unit and a plurality of fixtures comprising luminaires, optional control devices, and optional standalone sensors, wherein each fixture includes a co-located sensor capable of receiving the signal emitted by the pointing device, and a central control unit which can communicate bidirectionally with each fixture. Additional user gestures are disclosed together with methods for the central control unit to acknowledge gestures. Additional communications methods among components of the lighting system are also disclosed.
