SYSTEMS AND METHODS FOR CALIBRATING SOLID STATE LIGHTING PANELS USING COMBINED LIGHT OUTPUT MEASUREMENTS
First Claim
1. A method of 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 method comprising:
- activating the plurality of segments to simultaneously emit the first and second colors of light;
measuring a combined light output for the plurality of segments at a measurement location to obtain aggregate emission data; and
determining separate emission data for the first and second colors of light based on the aggregate emission data.

Abstract
A method of calibrating a lighting panel including a plurality of segments, a respective segment configured to emit a first color light and a second color light in response to pulse width modulation control signals having respective duty cycles, includes activating the plurality of segments to simultaneously emit the first and second colors of light. A combined light output for the plurality of segments is measured at a measurement location to obtain aggregate emission data. Separate emission data for the first and second colors of light is determined based on the aggregate emission data. For example, the separate emission data for the first and second colors of light may be derived based on extrapolation of the aggregate emission data and expected emission data for the first and second colors of light. Related calibration systems are also discussed.
