    摘要： A discharge lamp which eliminates the large line noise that forms in discharge lamps during startup while preventing heat loss in the transformer by providing a pair of opposed electrodes for the main discharge and an auxiliary electrode arranged such that it does not come into contact with the discharge space for the main discharge, a feed circuit for supplying the discharge current to the electrodes for the main discharge, and a starter circuit which produces a high voltage between one of the electrodes for the main discharge and the auxiliary electrode. The high voltage generating part of the starter circuit which includes at least a high voltage transformer that is separated from the feed circuit while the discharge lamp and the high voltage generating part are formed as an integral unit.

    摘要： To shorten the luminous flux rise time and prevent melting/deformation of the projections in the initial ignition period of high pressure discharge lamps that have a sealed mercury volume of no less than 0.20 mg/mm 3 , a power supply device feeds a current that exceeds the maximum current value of the constant power control period to the high pressure discharge lamp during a first control period from the initial discharge until the lamp voltage reaches a specified lamp voltage and causes a switch to constant power control, and then, during the following period until a change to steady power control, the power supply device feeds it a current that is less than the maximum current during regular operation.

    摘要： The restart properties of a light source even under the condition of a hot restart is improved, and suppression of the danger of an insulation breakdown in an unintended area is achieved by a light source comprising a discharge lamp in which a pair of main discharge electrodes are located opposite a discharge space; an auxiliary electrode arranged such that it does not come into contact with the discharge space; a feed circuit that supplies a discharge current to the main discharge electrodes; and a starter that produces a high voltage between one of the main discharge electrodes and the auxiliary electrode, wherein, during a time interval during which the starter produces said high voltage, a high voltage is also applied to the main discharge electrodes at least during a portion of the time interval.

    摘要： Light source device which includes a discharge lamp which contains at least 0.15 mg mercury per cubic millimeter of the volume of the discharge space, a pair of electrodes opposite one another to create the main discharge and spaced a distance from one another of less than or equal to 2.5 mm, and an auxiliary electrode arranged such that it does not come into contact with the discharge space for the main discharge. The light source device further including a feed circuit to feed the discharge current to the electrodes for the main discharge, and a starter which produces a high voltage between one of the electrodes of the two electrodes for the main discharge and the auxiliary discharge, such that the starter produces a voltage two to five times as high as the voltage necessary for starting the main discharge in the lamp at the room temperature state.
