| 摘要 |
Driving circuit comprises a first input, at which a first supply voltage is present, a second input, at which a second supply voltage is present, a first current supply unit selectively coupled to first or second input as function of at least one first control signal, at least one second current supply unit selectively coupled to first or second input as function of at least one second control signal, a control unit connected to first current supply unit and to at least one second current supply unit for respective control thereof and designed to provide at least one first and second control signal, and a first output coupled to first current supply unit to provide a first current for at least one first light-emitting diode, at least one second output coupled to at least one second current supply unit to provide second current for at least one second light-emitting diode.
