Patent attributes
A lighting control circuit (10) for controlling a plurality of LEDs (24, 26). The lighting control circuit (10) includes a current source (12) coupleable to a first LED (20) and a second LED (22); a first switch (24) configured to switch from an open position to a closed position when driven by a first drive signal (V3), wherein the first switch (24) is positioned to interrupt current flow (Iout) through the first LED (20) when the first switch (24) is in the open position; a second switch (26) configured to switch from an open position to a closed position when driven by a second drive signal (V4), the second drive signal (V4) being temporally non-overlapping with respect to the first drive signal (V3), wherein the second switch (26) is positioned to interrupt current flow (Iout) through the second LED (22) when the second switch (30) is in the open position.
