Patent abstract
A control method for a semiconductor light source may include operating the semiconductor light source with short, powerful pulses by an operating device; storing the characteristic light decrease of the semiconductor light source depending on the power introduced into the semiconductor light source in the operating device; and altering power introduced during the pulse in such a way that the emitted quantity of light of the semiconductor light source substantially remains constant over the pulse duration.
