Flash irradiation apparatus

A flash irradiation apparatus comprising:

• a flash discharge lamp that generates a flash by discharge;
• a lighting circuit including
• a capacitor that has a first terminal connected to an anode of the flash discharge lamp and stores electric charge to be supplied to the flash discharge lamp,
• a first switching element that switches between energization and non-energization of a connection between a cathode of the flash discharge lamp and a second terminal of the capacitor,
• a first diode having a cathode terminal connected to the first terminal of the capacitor and an anode terminal connected to the cathode of the flash discharge lamp, and
• a resistive element having a first terminal connected to the cathode of the flash discharge lamp;
• a second switching element that switches between energization and non-energization of a connection between the second terminal of the resistive element and the second terminal of the capacitor;
• and
• a controller that controls switching between energization and non-energization of the first switching element and the second switching element,
• wherein the controller executes
• first control to switch the second switching element from a non-energized state to an energized state,
• second control to switch the first switching element from the non-energized state to the energized state after executing the first control, and
• third control to switch the second switching element from the energized state to the non-energized state after executing the second control.
