Integrated circuit for illumination device, and illumination device
Abstract:
According to the present invention, anode-side ends of LED arrays (1011) and (1012) are connected to an identical point. A constant current circuit (1003) drives the LED array (1011) by a constant current, whereas, a constant current control circuit (3) drives the LED array (1012) by a constant current and by pulses.
