[origin: EP2182776A1] The lamp has a base unit (1) for positioning at a device, and lighting units (2.1-2.3) comprising lighting elements (8.1-8.3) e.g. red-green-blue (RGB)-LEDs. The lighting units have a power supply device for supplying power to the lighting elements. The lighting units have a control unit for controlling operating conditions of the lighting units with addressable interfaces (7.1-7.3) to a digital data transfer unit (5). The power supply device has two power conductors (6.1, 6.2), where one power conductor is designed as a data conductor for digital data transfer.
