Abstract

A circuit arrangement for operating a plurality of lighting devices having: a first control component, which is connected to a first lighting device or is formed integrally with a first lighting device; at least one second control component, which is connected to a second lighting device or is formed integrally with a second lighting device; at least one main control device, which is connected to the first and to the second control component and is configured to supply the control components with an operating voltage; and at least one data communications line, which is connected to the two control components and to the main control device. The main control device is is able to transmit a first position coding signal for the position coding of the first control component and at least one second position coding signal for the position coding of the second control component.
