    Abstract: A multi-color light unit includes a plurality of lighting circuits, with each lighting circuit being coupled to a joint power terminal. The plurality of lighting circuits include a first lighting circuit, which includes a first current source, coupled to the joint power terminal, a plurality of first LED's, in operation emitting light of a first color, and a plurality of voltage drop diodes, in operation not emitting light, the plurality of first LED's and the plurality of voltage drop diodes being coupled to the first current source. The plurality of lighting circuits further include a second lighting circuit, which includes a second current source, coupled to the joint power terminal, and a plurality of second LED's, in operation emitting light of a second color, the plurality of second LED's being coupled to the second current source. The first current source and the second current source are of equal design.
