Abstract
A high-pressure discharge lamp system has a high-pressure mercury lampand a lighting circuitthat operates the lamp. The lampincludes an envelope having a light emitting parthaving a first and a second electrodearranged therein and a first and a second sealing partoppositely extending from the light emitting part, and a conductorelectrically connected to the second electrode. Particularly a portion of the conductoris at least in contact with or in closest proximity to the outer surface of the first sealing partsubstantially at a single point in an area corresponding to a first metal foilconnected to the first electrode. The circuitactivates the lampby placing high-frequency voltage at a predetermined frequency within a range of 10 [kHz]-10 [MHz], inclusive, between the electrodes
