摘要：
Disclosed is a power supply device for light elements, including a first light element having a first color, a second light element having a second color, and a third light element having a third color. The power supply includes a power supply unit, a controllable switch coupled in series to the third light element in parallel to the second light element. The power supply unit has a first and a second output such that the first light element is coupled to the first output and the second and third light elements are coupled to the second output. The power supply unit provides adjustable output signals at the first and said second output such that the third light element radiates light when the switch is closed.
