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.

Abstract: The present invention relates to an optical component, comprising a substrate having a substrate surface (1), a radiation output element (2) situated on the substrate surface and/or a radiation input element (2) situated on the substrate surface and a beam deflection element (3) having dimensions of below 1 mm in all three spatial directions, which optical component is arranged on the radiation output or input element (2) on the substrate surface (1) and designed such that it deflects electromagnetic radiation exiting the radiation output element (2) substantially vertically with respect to the substrate surface (1) and in so doing forms a beam that has a smaller or even negative angle in comparison with the exit angle that the beam leaving the radiation output element forms with the substrate surface or is oriented parallel to the substrate surface, or that it focuses electromagnetic radiation entering the beam deflection element (3) at a particular angle with respect to the substrate surface and directs it
