The operating device as claimed in claim 1, wherein the operating device (10) sends information about the energy or power consumption, determined by the energy or power measuring device (25), to the control device (20) via the interface (15) on request by the control device (20) or intermittently independently.

3. The operating device (10) as claimed in claim 1, which furthermore has a data memory (30) which is coupled to the energy or power measuring device (25) so that the information about the energy or power consumption can be stored in the data memory (30).

4. The operating device as claimed in claim 3, which also has a further interface (35) which is coupled to the data memory (30) so that stored information about the energy or power consumption can be read out or sent via the further interface (35).

5. The operating device as claimed in claim 1, wherein the information about the energy or power consumption is an energy or power consumption averaged over time or an instantaneous energy or power consumption.

6. The operating device (10) as claimed in claim 1, wherein the operating device (10) sends to the control device (20) or rendering accessible to the control device (20) the information about the energy or power consumption intermittently, continuously, at periodic time intervals, at predetermined points in time, with a predetermined energy or power consumption or following a command for changing a brightness of the light-emitting means.

7. The operating device (10) as claimed in claim 1, wherein the operating device (10) receives control commands for the operation of the light-emitting means from a control unit (40) via the interface (15).
