Operating device for operating at least two lighting means (3, 4) in a bus-based DALI lighting system, wherein different operating device types are provided in the bus-based DALI lighting system, wherein the different operating device types relate to operating devices having a different functionality, provided in the DALI protocol, wherein the operating device is a two-channel or multi-channel operating device for separately operating two or more lighting means (3, 4) of the at least two lighting means (3, 4) on the respective channels; wherein the operating device has a controller for controlling the operating device as a first operating device type, wherein the controller is configured to process a received control signal of a first specification of the DALI protocol; characterized in that the operating device is designed, as a second operating device type, to process a received control signal of a second specification of the DALI protocol, wherein the first operating device type and the second operating device type are operating device types of the same standard, wherein the received control signal of the first specification contains information regarding a color temperature and a dimming level, wherein the received control signal of the second specification only contains information regarding a dimming level, wherein the operating device has an input circuit, wherein the operating device has a first connection (8a, 8b) and a second connection (9a, 9b) in each case for connecting the operating device to the bus-based DALI lighting system, wherein the input circuit is designed to selectively identify when the operating device is connected to the bus-based DALI lighting system by means of the first connection (8a, 8b) as the first operating device type, wherein the controller is designed to control the voltage and/or current output in each case in the first channel and the second channel according to the received control signal of the first specification; or when the operating device is connected to the bus-based DALI lighting system by means of the second connection (9a, 9b) as the second operating device type, wherein the input circuit is designed to convert the received control signal of the second specification into a new control signal with information regarding color temperature and dimming level based on the information regarding the dimming level of the received control signal of the second specification, and wherein the controller is designed to control the voltage and/or current output in each case in the first channel and the second channel according to the new control signal. wherein different operating device types are provided in the bus-based DALI lighting system, wherein the different operating device types relate to operating devices having a different functionality, provided in the DALI protocol, wherein the operating device is a two-channel or multi-channel operating device for separately operating two or more lighting means (3, 4) of the at least two lighting means (3, 4) on the respective channels; wherein the operating device has a controller for controlling the operating device as a first operating device type, wherein the controller is configured to process a received control signal of a first specification of the DALI protocol; characterized in that the operating device is designed, as a second operating device type, to process a received control signal of a second specification of the DALI protocol, wherein the first operating device type and the second operating device type are operating device types of the same standard, wherein the received control signal of the first specification contains information regarding a color temperature and a dimming level, wherein the received control signal of the second specification only contains information regarding a dimming level, wherein the operating device has an input circuit, wherein the operating device has a first connection (8a, 8b) and a second connection (9a, 9b) in each case for connecting the operating device to the bus-based DALI lighting system, wherein the input circuit is designed to selectively identify when the operating device is connected to the bus-based DALI lighting system by means of the first connection (8a, 8b) as the first operating device type, wherein the controller is designed to control the voltage and/or current output in each case in the first channel and the second channel according to the received control signal of the first specification; or when the operating device is connected to the bus-based DALI lighting system by means of the second connection (9a, 9b) as the second operating device type, wherein the input circuit is designed to convert the received control signal of the second specification into a new control signal with information regarding color temperature and dimming level based on the information regarding the dimming level of the received control signal of the second specification, and wherein the controller is designed to control the voltage and/or current output in each case in the first channel and the second channel according to the new control signal.
