Abstract

A control device includes a data bus interface, which can be a CAN bus data bus interface, a computer core (microcontroller) and a number nLED of a plurality of driver circuits, wherein nLED is a positive integer greater than 1. Each driver circuit is designed to be able to supply at least one lamp group with electrical power. The nLED driver circuits are thus designed to be able to supply at least nLED lamp groups with electrical power. Each lamp group comprises one or more lamps, which can comprise one or more light-emitting diodes. The data bus interface and the computer core (microcontroller) and the nLED driver circuits are accommodated on a common semiconductor substrate.
