Patent ID: 7986107

Claim:
An electrical circuit comprising: a first color string and a second color string directly coupled in series, wherein each of the color strings has at least one LED, and further wherein the second color string is coupled to ground; a power supply configured to provide power to the first color string and the second color string; a first capacitor and a second capacitor, wherein the first capacitor is coupled in parallel to the first color string and the second capacitor is coupled in parallel to the second color string, and further wherein the first capacitor is coupled in series to the second capacitor, and the second capacitor is coupled to ground; a first switch and a second switch, wherein the first switch is coupled to a first inductor at a first terminal of the first switch and coupled to a second inductor at a second terminal of the first switch, and the first switch coupled to the first inductor and the second inductor is further coupled in parallel to the first color string, and further wherein the second switch is coupled to the second inductor at a first terminal of the second switch and coupled to a third inductor at a third terminal of the second switch, and the second switch coupled to the second inductor and the third inductor is further coupled in parallel to the second color string, wherein the first switch is configured to shunt power away from the first color string, and the second switch is configured to shunt power away from the second color string.
