摘要： A resonant transformer is disposed at a stage following an inverter for inverting the polarity of a voltage applied to a discharge lamp. A parallel resonant circuit is formed by a resonant capacitor and a primary winding of the resonant transformer, and a periodic voltage applying section is connected to the parallel resonant circuit. The periodic voltage applying section is operated at a frequency that causes resonance in the parallel resonant circuit, thereby applying a high AC voltage to the discharge lamp in a period in which discharge is started in the discharge lamp.

摘要： A discharge lamp lighting device can reduce a variation in luminous flux at the time when the polarity of a voltage to be applied to the discharge lamp is inverted, prevent an excessively large amount of current from flowing through the discharge lamp at the time of starting, prevent the fade-out of discharge when the discharge mode returns from an arc discharge mode to a glow discharge mode, and reduce the ripple of a lamp current in a normal lighting mode. A coil is provided in an output current path of a power supply circuit comprising, for example, a step-down chopper, and a smoothing capacitor is provided in the next stage of the coil so that it selectively is turned on or off by a switching element. An inverter comprising, for example, a full bridge is provided in the next stage of the smoothing capacitor.

摘要： 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.
