摘要： A control circuit comprises a rectifier unit for performing full wave rectification on an AC power source, a switching element for switching a current flowing through a light emitting device which emits light in response to a voltage having been full wave rectified in the rectifier unit, a voltage dividing circuit for dividing the voltage having been full wave rectified in the rectifier unit to obtain a reference voltage Vref, a comparator for comparing a comparison voltage Vcmp corresponding to the current flowing through the light emitting device with the reference voltage Vref, and a control unit for controlling switching of the switching element based on a comparison result obtained in the comparator.
