Electronic flash unit and manufacturing method thereof

摘要

The electronic flash unit disclosed comprises: a transformer ( 14 ) to vary voltages of a power supply; an accumulator ( 16 ) composed of a main capacitor ( 17 ) to charge an electric energy supplied from the transformer ( 14 ); a lamp unit ( 4 ) provided with a flashlamp ( 20 ), set inside of a reflector ( 19 ), that flashes by discharging of energy storages in the main capacitor ( 17 ) upon applying a voltage on a trigger terminal ( 21 ); and a trigger circuit ( 10 ) to generate the voltage to apply on the trigger terminal ( 21 ), wherein at least the lamp unit ( 4 ) is coated with an insulation material.
