Abstract: The present invention relates to a method for providing control signals for a light whose color or color temperature is variable. The invention also relates to a corresponding control apparatus and a corresponding lighting system. In the method, a series of at least three color locations (F1, F2, F3) is determined, which lie on a predetermined color change curve (K1) in a corresponding coordinate system. By way of example, the color change curve may be the Planck curve train or a straight line. The color locations (F1, F2, F3) are in this case chosen such that the respectively corresponding colors have a color distance (d) which, at least approximately, is subjectively perceived as in each case being of the same magnitude. This makes it easier to adjust the light to give a specific desired light impression.

Abstract: A control circuit of a DC/DC converter is provided for supplying a driving voltage to a light emitting element. A hysteresis comparator compares a detection voltage that corresponds to the output voltage of the DC/DC converter with two threshold voltages. If the detection voltage is smaller than the lower threshold voltage, the hysteresis comparator outputs a comparison signal at the low level. Otherwise, the comparison signal is set to the high level. The switching control unit uses the comparison signal as a reference. The switching control unit instructs the switching transistor of the DC/DC converter to perform the switching operation during a period when the comparison signal is at the low level. Otherwise, the switching operation is suspended. The control circuit inhibits light emission of the light emitting element during a period when the comparison signal is at the low level. Otherwise, the control circuit permits the light emission.
