Abstract:
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 (V 3 ), wherein the first switch ( 24 ) is positioned to interrupt current flow (I out ) 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 (V 4 ), the second drive signal (V 4 ) being temporally non-overlapping with respect to the first drive signal (V 3 ), wherein the second switch ( 26 ) is positioned to interrupt current flow (I out ) through the second LED ( 22 ) when the second switch ( 30 ) is in the open position.

Claim (Index 1):
A lighting control circuit, comprising:\n a controller for generating a first drive signal, a second drive signal and a reference voltage, the second drive signal being temporally non-overlapping with respect to the first drive signal; a current source coupleable to deliver a current to a first LED and a second LED, wherein the current is proportional to the reference voltage so that a desired value of the current is achieved when the reference voltage has a high value; a first switch configured to switch from an open position, when driven by the first drive signal having a low value, to a closed position when driven by the first drive signal having a high value, wherein the first switch is positioned to interrupt current flow through the first LED when the first switch is in the open position; and a second switch configured to switch from an open position, when driven by the second drive signal having a low value, to a closed position when driven by the second drive signal having a high value, wherein the second switch is positioned to interrupt current flow through the second LED when the second switch is in the open position, wherein the controller is arranged to generate the high value of the reference voltage only after one of the first drive signal and the second drive signal has the high value.
