Abstract
A high-voltage discharge lamp lighting apparatus has a stabilizer which supplies a power voltage used for maintaining the lighting operation to a high-voltage discharge lamp, and an ignitor circuit having an oscillating circuit-for-driving in which a start pulse generates upon starting the lighting operation of the high-voltage discharge lamp, and high-voltage pulse generating transformers which increase a voltage of the start pulse. Further, the high-voltage discharge lamp lighting apparatus includes a cap portion to which the high-voltage discharge lamp is attached and held, including a part of the high-voltage pulse generating transformers of the ignitor circuit, and a socket portion to which the cap portion is attached and is fit, including at least the oscillating circuit-for-driving in the ignitor circuit and a portion of the high-voltage pulse generating transformers except for a part included in the cap portion.
