Lighting systems and methods of auto-commissioning

Abstract

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 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.
