    摘要: Provided is a method for lighting a high pressure discharge lamp capable of increasing the life thereof. The lighting method is as follows. When the time elapse after lighting up the discharge lamp is within a predetermined condition (e.g. 5 minutes or less), constant current control is performed if the lamp voltage is lower than switching voltage (here, a first voltage value V1) and constant power control is performed to maintain the lamp power at a power value W1 if the lamp voltage is equal to or above the switching voltage. After the predetermined condition (5 minutes) is exceeded, the constant power control is performed by lowering the value of the switching voltage from the first voltage value V1 to the second voltage value V2. If the lamp voltage is equal to or above the switching voltage lowered, the lamp power is maintained at power value W1.

    摘要: A high-pressure discharge lamp lighting device that suppresses deterioration and the expansion of inter-electrode distance in a pair of electrodes within a high-pressure discharge lamp, more effectively than conventional technology. The frequency of the AC current supplied to a high-pressure discharge lamp alternates between a first frequency and a second, higher frequency, while the magnitude of the AC current alternates between a first value and a second, higher value. The suppressing effect is realized by repeatedly alternating the frequency and repeatedly alternating between a first period at the first frequency and a second period at the second frequency, with the second, higher-magnitude current being used in the latter and the first current being used in the former.

    摘要: 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.

    摘要: A first waveform (a rectangular waveform, for example) is applied as the waveform of the alternating current supplied to a high-pressure discharge lamp for a predetermined time from the beginning of lighting of the lamp and a second waveform (a staircase waveform, for example) is applied as the waveform of the alternating current after the elapse of a predetermined time (100 [s], for example). The alternating current with the first waveform has a lower absolute instantaneous value in a final section of each half-cycle period thereof than in the other sections and the alternating current with the second waveform has a higher absolute instantaneous value in a final section of each half-cycle period thereof than in the other sections.
