Abstract
A method for turning on or off a first and/or a second laser diode of an illumination device. A first laser diode of the illumination device for emitting a first light beam within a first wavelength range is turned on by a control unit of the illumination device. The first wavelength range changes depending on a temperature of the first laser diode. The first laser diode is turned off by the control unit depending on a comparison of a first wavelength value of the first light beam emitted by the first laser diode with a first wavelength threshold value. A second laser diode of the illumination device for emitting a second light beam within a second wavelength range is turned on or left on by the control unit at the second point in time depending on the comparison of the first wavelength value with the first wavelength threshold value.
