Patent ID: 8408735

Claim:
An actuating device for operating lamps, the device comprising: light emitting diodes including actuatable first light-emitting diodes for generating a first white light and actuatable second light-emitting diodes for generating a blue light; an actuator for actuating the first light-emitting diodes to generate said first white light, and also for actuating the second light-emitting diodes to generate said blue light such that only the first light-emitting diodes are switched on in a first operating state of the operating lamp and that the first light-emitting diodes and the second light-emitting diodes are switched on in a second operating state to generate a second white light, wherein the second light-emitting diodes are designed such that a general color rendering index R a and a color rendering index R 9 is greater than 70, and a color temperature in the second operating state is greater than a color temperature in the first operating state of the operating lamp.
