Actuating device for operating lamps
First Claim
1. 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 Ra and a color rendering index R9 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.

Abstract
An actuating device for operating lamps (1) includes an actuator provided for actuating a number of first light-emitting diodes (6) for generating white light, on the one hand, and a number of second light-emitting diodes (7) for generating single-color light, on the other hand. A control is provided such that only the first light-emitting diodes (6) are switched on in a first operating state of the operating lamp (1) and such that the first light-emitting diodes (6) and the second light-emitting diodes (7) are switched on in a second operating state. The second light-emitting diodes (7) 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 (1).

11. An operating lamp comprising:
-
a plurality of first light-emitting diodes for generating a first white light with a first general color rendering index; a plurality of second light-emitting diodes generating a blue light, a combination of said first white light and said blue light creating a second white light, said first and second light emitting diodes being arranged to have said second white light have a second general color rendering index Ra and a color rendering index R9 that is greater than 70, said second white light having a color temperature greater than a color temperature of said first white light; a light module accommodating said first light-emitting diodes and said second light-emitting diodes to emit the respective light in a similar direction; an actuator for actuating said first light-emitting diodes, and also for actuating said second light-emitting diodes, said actuator selectively switching between a first operating state of the operating lamp with said first light-emitting diodes on and said second light-emitting diodes off, and a second operating state with said first light-emitting diodes and said second light-emitting diodes on. - View Dependent Claims (12, 13, 14)
