Spectral coordinates, forward voltage, and environmental measurements for the as manufactured assembly are measured for each base color LED. The measurements are recorded to a storage device internal to the LED assembly. Those stored measurements can then be utilized in usage of the LED assembly to provide accurate and precise control of the light output by the LED assembly.
A controller for controlling a light emitting diode (LED) light engine. The controller includes a temperature sensor configured to sensor temperature at the LED light engine. A current sensor senses a drive current of the LED light engine. A voltage differential sensor senses a voltage differential across LEDs of the LED light engine. A timer monitors a time of operation of the LED light engine. Further, a control device controls the drive current to the LED light engine based on the sensed temperature, the sensed drive current, the sensed voltage differential, and the monitored time of operation. Further, the control device outputs an indication of intensity degradation of an LED, and if the intensity degradation exceeds a predetermined threshold the control can output an indication of such to a user, so that the user can be apprised that the LED needs to be changed.
