A lighting device, such as a controllable light-emitting diode (LED) light source, may execute a self-calibration procedure to compensate for changes in an optical system of the lighting device that may have occurred after an initial factory calibration procedure. The lighting device may include an emitter, a detector that generates a detector signal in response to detected light, a memory that stores a curve defining an optical compensation value with respect to a measured forward voltage of the detector, and a control circuit configured to receive a measured value of a luminous flux of the light emitted by the emitter that may be determined in response to the detector signal and based on the optical compensation value. The control circuit may adjust the curve defining the optical compensation value in response to a difference between the measured value and an expected value of the luminous flux.
A light-emitting diode (LED) lighting controller, comprising:
A light-emitting diode (LED) lighting fixture control method, comprising:
A non-transitory, machine-readable, storage device that includes instructions that, when executed by a control circuit in a light-emitting diode (LED) lighting fixture, cause the control circuit to:
