Patent ID: 8585212

Claim:
A lighting system comprising: a first light source configured to generate light signals of a first color; and at least one second light source configured to generate light signals of a second color; wherein the first and second light sources are configured to be driven so as to generate a predeterminable color sequence of individual colors; wherein the first and second light sources are configured to be operated by a common control unit and to be driven by said common control unit in a sequence required for generating the predeterminable color sequence; wherein the light sources are connected in parallel and are electrically coupled to an energy supply unit via a first circuit node in order to supply energy; wherein the lighting system comprises a regulator unit for regulating the energy supply unit and coupled to the control unit via a signal line; wherein the control unit is configured to predetermine a desired energy output of the energy supply unit via the regulator unit depending on an individual color within the color sequence; wherein the lighting system comprises a number N of light sources, at least a number N−1 of light sources each being connected in series with a respective switch in a signal path, each respective switch being drivable by the control unit; and wherein the energy supply unit is a step-down converter or a buck converter, the energy supply unit has one inductor for each light source, each light source is connected to a respective inductor via each output node, the energy supply unit has an input terminal at which a voltage source with respect to a reference potential can be fed in, and one freewheeling diode is connected between each output node and the input terminal.
