摘要： A control circuit performs ON/OFF control for a switching element so that LED current flowing in an LED unit is within a rated current range. In the case where the LED unit is lit, a voltage applied between both ends of series connection of a reactor and the LED unit becomes a first bus voltage, when the switching element is ON, and becomes a voltage lower than the first bus voltage, that is determined based on the first bus voltage and a second bus voltage, when a switching element is OFF.

摘要： There is obtained an ignition apparatus, for an internal combustion engine, that can make a predetermined output current flow in a stable manner so that the combustion state of the internal combustion engine can always be maintained in a good condition, even in the case where the voltage of the power source connected with the energy storing coil fluctuates. There are provided an energy storing coil (3), a switching means (S1) for accumulating energy, an ignition coil (4), and a switching means (S2) that turns on/off an ignition current; the switching means (S1) and (S2) are alternately turned on/off so that a current with a alternating polarity is made to flow continuously in the ignition coil (6); a switching means (S3) is connected both terminals of the energy storing coil (3); and when a current flowing in the energy storing coil (3) reaches a target value, the switching means (S1) is turned off and the switching means (S3) is turned off so that the energy storing coil current circulates through the switching means (S3) so as to keep the current to be approximately the target value.
