Abstract:
The present invention proposes to use a power negotiation connection (e.g. the VBUS channel) of a power delivery interface for transmitting or receiving control commands or, respectively, status information to/from a lighting device. The power negotiation connection can be used as a communication channel that is fully independent of the data connection. It uses, for example, different protocols and different wires than the data connection. Control commands, such as dim level or color, can be encoded in a vendor defined message of a related power negotiation protocol.
