<p>A high-voltage discharge lamp lighting apparatus has a stabilizer (12) which supplies a lighting sustaining power source voltage to a high-voltage discharge lamp (20) and an igniter circuit comprising a driving oscillation circuit (13) for generating a start pulse upon the lighting start of the high-voltage discharge lamp and high-voltage pulse generating transformers (14a, 14b, 14c) for boosting the start pulse. This apparatus comprises a mouth section (16), with the high-voltage discharge lamp (20) mounted and retained and a built-in part of the high-voltage pulse generating transformers of the igniter circuit, and a socket section (11) with this mouth part (16) jointed and mounted with the built-in part of the high-voltage pulse generating transformers other than built in the driving oscillation circuit (13) of at least the igniter circuit and in the mouth section (16). The primary winding (14a), secondary winding (14b), and magnetic core (14c) of a high-voltage pulse generating transformer are dividedly housed and disposed inside the mouth section (16) and the socket section (11). This constitution causes no high voltage to remain in the connection segment of each section when the mouth section (16) is removed from the socket section (11). A worker is prevented from getting an electric shock, and the cost at the time of lamp replacement is reduced.</p> |
