7. The light emitting device system of claim 5, wherein the emulation circuit is adapted for emulating the electrical load of the light emitting device system with respect to an external potential, wherein the external potential is different from the potential of the power supply terminals.

8. A driver for an external light emitting device system comprising power supply terminals and a detector circuit, the power supply terminals being adapted for supplying electrical power from the driver to the light emitting device system and the detector circuit being adapted for capturing remote control signal information of the light emitting device system exclusively via the supply terminals and/or via wireless reception and for determining a remote control signal received by the light emitting device system, using the remote control signal information, wherein the driver is further adapted to control the supplied power, depending on the determined remote control signal.

9. The driver of claim 8, wherein the detector circuit is adapted for capturing the remote control signal information of the light emitting device system via the supply terminals by sensing an electrical load of the terminals caused by the light emitting device system.
