Patent ID: 8514210

Claim:
A calibration system for calibrating a lighting panel comprising a plurality of segments, a respective segment configured to emit a first color of light and a second color of light in response to pulse width modulation control signals having respective duty cycles, the calibration system comprising: a calibration controller configured to be coupled to the lighting panel; and a calibration unit coupled to the calibration controller and comprising a colorimeter, wherein the calibration unit further comprises an XY positioner connected to the colorimeter and configured to move the colorimeter to a measurement location in two dimensions, wherein the calibration controller is configured to activate the plurality of segments to simultaneously emit the first and second colors of light, wherein the calibration unit is configured to measure a combined light output from the plurality of segments at the measurement location to obtain aggregate emission data, and wherein the calibration controller is configured to determine separate emission data for the first and second colors of light based on the aggregate emission data.
