Patent ID: 7569997

Claim:
A Light Emitting Diode (LED) lighting control system comprising: a controller generates electric current data and brightness data wherein the electric current data and the brightness data are latched into latch data signals being transmitting to a driver integrated circuit (IC) by a latch circuit; and a counter circuit defines a counter value to be an initial value; a logic operation circuit receives the counter value from the counter circuit, and receives the latch data signals from the data latch circuit; the logic operation circuit determines number of image cycles in accordance with a predetermined bit data (bd) wherein the number of image cycles is 2 bd ; a current driving circuit flows electric current in accordance with light intensity; the counter circuit increments the counter value by one (1); and the logic operation circuit compares the counter value with the number of image cycles, and if the counter value is not greater than the number of image cycles and no new latch data signals are received, the current driving circuit flows electric current in accordance with the light intensity.
