Abstract:
A system includes a first solid-state lamp that generates a first illuminated output having a first color. A second solid-state lamp generates a second illuminated output having a second color. The second illuminated output is mixed with the first illuminated output to generate a third illuminated output having a third color. An inductor or a transformer includes a primary coil and a bias coil. A first circuit includes the primary coil and a first switch. The first circuit supplies power to the first solid-state lamp. A second circuit includes the bias coil and a second switch. The second circuit supplies power to the second solid-state lamp. A control module alters the third color including controlling (i) a state of the first switch to adjust current supplied to the first solid-state lamp, and (ii) a state of the second switch to adjust current supplied to the second solid-state lamp.
