A drive device for a light emitting component includes a reference source for generating a power stipulation signal that stipulates a desired power. A correction device compensates for a temperature-dictated measurement error of the photodetector by modifying, in a temperature-dependent manner, the power stipulation signal generated by the reference source. A regulating device is connected to the reference source and generates a regulating signal that regulates the light power of the light emitting component to minimize the deviation between the actual l...
1. A drive device for a light-emitting component, comprising:a reference source for generating a power stipulation signal stipulating a desired light power; a photodetector for measuring an actual light power of the light-emitting component; a regulating device connected to said photodetector and said reference source, said regulating device generating a regulating signal for regulating the actual light power of the light-emitting component such that a deviation between the desired light power and the actual light power becomes minimal; and a correction ...
