Calibrating a light sensor
First Claim
1. A method of calibrating an output of a light sensor for use in controlling a lighting system comprising at least one lighting device operable to output light with a plurality of different beam shapes, the method comprising:
- placing the lighting system into each of a plurality of discrete modes, each mode being configured to output a different respective configuration of light comprising a different respective pattern of one or more of the different beam shapes, said modes being beam modes of the lighting device; and
performing a plurality of calibrations by determining a respective calibration setting for calibrating the output of the light sensor in each of the modes, wherein in operation each mode will automatically vary an output illumination level of the respective configuration of light, in response to a changing light level in an environment being illuminated, based on the output of the light sensor as calibrated by the respective calibration setting.

Abstract
A method of calibrating an output of a light sensor for use in controlling a lighting system comprising at least one lighting device. The method comprises placing the lighting system into each of a plurality of discrete modes, each mode being configured to output a different respective configuration of light, wherein in operation each mode will automatically vary an output illumination level of the respective configuration based on the output of the light sensor in response to a changing light level in an environment being illuminated. The method further comprises performing a plurality of calibrations by determining a respective calibration setting for calibrating the output of the light sensor in each of the modes, and setting each mode to vary the output illumination level based on the output of the light sensor as calibrated by the respective calibration setting.
