Abstract: A light source device in which a discharge lamp, which contains greater than or equal to 0.15 mg mercury per cubic millimeter of the volume of the discharge space, and in which there is a pair of electrodes disposed opposite one another, is connected to a feed device (Ex). The feed device is used to start the discharge lamp and to supply the discharge current to the electrodes. The feed device (Ex) serves an identification function identifying a discharge state of the discharge lamp as a glow discharge state. Further, during the identification of the glow discharge state, the electric power supplied to the discharge lamp is set at less than or equal to twice as high as the nominal electric power of the above described discharge lamp to eliminate the formation of blackening on the inside of the bulb glass during glow discharge.

Abstract: 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.

Abstract: In a dielectric-barrier discharge lamp light source comprising a dielectric-barrier discharge lamp (2) and a power supply for impressing a roughly cyclical, high-voltage alternating current on the electrodes (4, 5) of the above-mentioned dielectric-barrier discharge lamp which has a discharge plasma space (3) filled with a discharge gas in which excimer molecules are formed by dielectric-barrier discharge, and in which at least one of the electrodes (4, 5) for inducing the discharge phenomenon is separated from the discharge gas by dielectrics (6, 7), there is a period of gradual change in the lamp voltage before reaching the voltage for the beginning of the next effective discharge (+Ei, -Ei) after completion of one discharge and when the voltage impressed on the lamp changes toward the next discharge. Also, for the ratio DELTA Vy/ DELTA Vx the condition 0.3 ≤ DELTA Vy/ DELTA Vx ≤ 0.9 (formula 3) is fulfilled, when a voltage when one discharge is completed is denoted VA, a differential voltage between the voltage VA and a voltage VB after completion of the next voltage is denoted DELTA Vx, i.e., when DELTA Vx = VA - VB (formula 1), and when a differential voltage between the voltage VA after one discharge is completed and a voltage VF at the end of the period of gradual change of the voltage impressed on the above-mentioned lamp is denoted DELTA Vy, i.e., when DELTA Vy = VF - VA (formula 2).
