摘要： A method and apparatus for operating a high pressure discharge lamp is disclosed. Oscillation in the discharge arc periphery, a problem that occurs with high frequency operation, is eliminated. A high pressure discharge lamp is operated by applying thereto a dc or rectangular wave current to which is superposed an ac component shaped by a high frequency ripple signal that has been amplitude modulated by a modulation signal for inducing instantaneous fluctuations in the power supply input to both ends of the arc gap. The ripple level is thereby temporally varied, and stable operating is possible even when exceeding the ripple level at which oscillation in the arc periphery begins.

摘要： A pair of electrodes (3) are provided in an arc tube (1) I/S is 20 (A/mm2) or less on a condition that an area of a cross section at a tip of the electrodes (3) is S (mm2) and an operating current between the electrodes (3) is I (A). According to this constitution, a long lamp life can be obtained without causing a rise in the lamp voltage and the blackening of the arc tube (1) by the evaporation of the electrodes while operation time becomes longer.

The sound standing wave is of a given mode, and is in a radial direction with respect to the arc tube. The given mode corresponds to, for example, a first-order mode. Preferably, the arc tube satisfies a relation as follows:(n+0.2).ltoreq.2L/D.ltoreq.(n+0.8)where "n" denotes a natural number, and "L" denotes an axial length of an interior of the arc tube and "D" denotes an inside diameter of the arc tube.

摘要： A fill material 201 enclosed in an arc tube 201 with an inner diameter of 10.8 mm includes ScI3, argon, and mercury. A distance between electrodes 202 is set at 2.2 mm, and a distance between the inner wall of the arc tube 201 and the electrodes 202 is set at approximately 5.4 mm, which is approximately twice the distance between the electrodes 202. The lamp of the present invention is capable of forming thin arc and thereby achieving high luminance since only the metallic elements having an ionization potential of 6 eV or higher is contained in the fill material 207. The restriction of the short distance between the electrodes serves to stabilize arc. Scandium in the fill material serves to achieve a good color reproduction characteristic.
