Abstract
There is provided a high-voltage pulse generator with a reduced radius of rotation and improved performance, and a lighting apparatus and a vehicle having the high-voltage pulse generator. The high-voltage pulse generator includes a pulse transformer in which a primary winding and a secondary winding are wound on a core, a discharge lamp connector which is formed in a tube shape having an opened front surface and a bottom out of an insulating material and which has an inner-electrode terminal electrically connected to a high voltage part of the secondary winding in the bottom, and a pulse generating capacitor and a discharge switch electrically connected to the primary winding of the pulse transformer. The discharge lamp connector is disposed so that the center thereof is located in a center line passing through a substantial center in an axis direction (a direction parallel to a center line) of the pulse transformer and perpendicular to the axis direction. The capacitor and the discharge switch are disposed to be opposed to the high voltage part of the secondary winding and a high voltage area including the inner-electrode terminal with the discharge lamp connector therebetween.
