    • A high-pressure discharge lamp system has a high-pressure mercury lamp 4 and a lighting circuit 3 that operates the lamp 4. The lamp 4 includes an envelope having a light emitting part 6 having a first and a second electrode 10, 11 arranged therein and a first and a second sealing part 7, 8 oppositely extending from the light emitting part 6, and a conductor 20 electrically connected to the second electrode 11. Particularly a portion of the conductor 20 is at least in contact with or in closest proximity to the outer surface of the first sealing part 7 substantially at a single point in an area corresponding to a first metal foil 16 connected to the first electrode 10. The circuit 3 activates the lamp 4 by placing high-frequency voltage at a predetermined frequency within a range of 10 [kHz]-10 [MHz], inclusive, between the electrodes 10, 11.

    • Constant current control is performed after the completion of starting operation of a high-pressure mercury-vapor lamp 4 and then lighting is shifted to constant power lighting. Except during a modulation forbidden period as a certain period from the completion of the starting operation, the frequency of an alternating current is subjected to frequency modulation control for being modulated to at least a first frequency and a second frequency having higher audibility than the first frequency. During the modulation forbidden period defined as a period from the completion of the starting operation until a predetermined time before lighting is shifted to constant power lighting, from the completion of the starting operation until lighting is shifted to constant power lighting, or from the completion of the starting operation until a predetermined time after lighting has been shifted to constant power lighting, the frequency modulation control is not performed and an alternating current with a third frequency lower than the second frequency is supplied. The quietness can be increased without adversely affecting the frequency modulation control on an alternating current for properly growing and maintaining protrusions of electrodes.
    • 在高压汞蒸汽灯4的启动操作完成之后进行恒定电流控制,然后将照明转移到恒定电力照明。 除了在从启动操作完成起的一段时间内的调制禁止期间,对交流电的频率进行频率调制控制,以便被调制成具有比第一频率更高的可听性的至少第一频率和第二频率 。 在调制禁止期间被定义为从开始操作完成到点亮之前的预定时间转移到恒定功率照明的时间段之间,从开始操作完成到点亮转移到恒定功率照明,或从完成 直到点亮之后的预定时间已经转移到恒定功率点亮的开始操作,不执行频率调制控制,并且提供具有低于第二频率的第三频率的交流电。 可以增加静音,而不会对用于适当地生长和保持电极突起的交流电的频率调制控制产生不利影响。
