ABSTRACT:
A discharge lamp unit which does not require enlargement of the discharge lamp and can still prevent application of a high voltage to a cap holder when the lamp is not connected includes a core of a high-voltage transformer inside a cap of the discharge lamp. Both a primary coil and a secondary coil of the high-voltage transformer are provided around a cap holder of the discharge lamp power supply. The cap of discharge lamp is inserted into the cap holder of the discharge lamp power supply to provide an electromagnetic link between the primary coil and the secondary coil of the high-voltage transformer.
