Abstract
An actuating device for operating lamps () includes an actuator provided for actuating a number of first light-emitting diodes () for generating white light, on the one hand, and a number of second light-emitting diodes () for generating single-color light, on the other hand. A control is provided such that only the first light-emitting diodes () are switched on in a first operating state of the operating lamp () and such that the first light-emitting diodes () and the second light-emitting diodes () are switched on in a second operating state. The second light-emitting diodes () are designed such that a preset color rendering index is greater in the second operating state than in the first operating state of the operating lamp ().
