Abstract:
Various embodiments include apparatuses and methods control apparatus to color tune a light-emitting diode (LED) array. In one specific example, a control apparatus to color tune a light-emitting diode (LED) array for perceptually uniform color-tuning is disclosed. The apparatus includes a correlated color temperature (CCT)-control device that is adjustable by an end-user to a desired color temperature of the LED array and producing an output signal corresponding to the desired color temperature. A storage device is electrically coupled to the CCT-control device to correlate a mechanical movement range of the CCT-control device to provide substantially uniform increases in perceptual CCT values from the LED array based on a set of N predetermined values. Other apparatuses and methods are described.
