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 4):
The lighting control circuit of  claim 1 , further comprising:\n a current control loop, comprising:\n an error amplifier, configured to receive at a first input a sense voltage being proportional the current flowing through LED strings, and to receive at a second input a reference voltage, and to output an error voltage, wherein the error voltage is proportional to the difference between the sense voltage and the reference voltage; \n a comparator, configured to receive at a first input the error voltage, and at a second input a comparison voltage, the comparison voltage being a sawtooth wave, and to output a control voltage, wherein the duty cycle of the control voltage is set by the magnitude of the error voltage, \n wherein the current source is configured to adjust the magnitude of the output current in proportion to the duty cycle of the control voltage.
