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.

摘要： To provide a high-pressure mercury lamp capable of shortening the light output rise time and of preventing glow discharge that occurs when the lamp is lighted, a high-pressure mercury lamp luminescent device with a pair of electrodes placed opposite one another within a discharge vessel made of quartz glass with seals formed on both ends and at least 0.15 mg/mm 3 of mercury sealed into the discharge vessel, has a device for increasing the temperature of the outer wall of the luminescent portion of the discharge vessel to at least 100 °C before the high-pressure mercury lamp is lit.
