Abstract

A lighting system, a lighting unit and a method for controlling a plurality of light sources are described. A lighting system comprises an intelligent electrical current supply 12 to supply an electrical current with modulated command data. A plurality of lighting units 4, 6, 8 are connected in series to the current supply 12. Each lighting unit comprises a light source 22, a controllable bypassing switch 24 to selectively bypass the light source and a control unit 26. The control unit receives the modulated command data and controls the bypassing switch 24 accordingly.
