摘要：In an LED control device 100, a first integration circuit Z1 changes a first

reference signal REF1 to be different from a second reference signal REF2 in one cycle ofa first PWM light controlling signal PWM1, and a first control unit CON1 controls a firstswitching element SW1 by means of a first control signal Gate1 at a first operationalfrequency for turning on and off a first switching element SW1, the first operationalfrequency being different from a second operational frequency for turning on and off asecond switching element SW2, in one cycle of a first PWM light controlling signal PWM1.
