Method of controlling a lighting emitting diode lighting device and a light emitting diode, LED, based lighting device
Abstract:
A method of controlling a multicolor LED lighting device is discloses. The LED lighting device comprises at least two series-connected LED light sources with different color metric values and supplied with a current, each LED light source is controlled by a respective switch operating according to a duty cycle. The method adapts an operating current amplitude supplied to the multicolor LED lighting device based on a color point that is required by a user. The method comprises the steps of receiving a designated color metric value for the LED lighting device; determining an operating current amplitude for the LED lighting device based on a current profile over a range of color metric values and the designated color metric value, and setting the current supplied to the LED light sources to the determined operating current amplitude.
