发明名称 Control system for light-emitting device
摘要 A control system for a light-emitting device may include test circuitry, photodetectors, and process circuitry. The test circuitry is configured to sequentially drive individual groups of light-emitting elements in a light-emitting device during a test sequence. Each group of light-emitting elements includes one or more light-emitting elements. The photodetectors are configured to detect an intensity of light present at a plurality of locations of the light-emitting device during the test sequence and generate a detection signal corresponding to the detected intensity of light. The process circuitry is configured to process the detection signals and transmit an adjustment signal based on the processing. The light-emitting elements may then be driven such that at least one characteristic of light emitted by all of the plurality of light-emitting elements is substantially the same at each of the plurality of locations of the light-mixing region.
