摘要： An image projector has a lamp unit 23 having a high-pressure mercury vapor discharge lamp 21 and a parabolic mirror 22. To the high-pressure mercury vapor discharge lamp 21, a driving system 24 applies an alternating voltage such that wandering of a cathode luminescent spot generated in the vicinity of a tip of each of the discharge electrodes of the high-pressure mercury vapor discharge lamp 21 is suppressed, the frequency being within the range of 20-42 kHz. This construction allows to prevent flicker in a projected image of a liquid crystal projector and the like, and therefore achieves high quality in the projected image.

摘要： The present invention provides a high pressure discharge lamp which is provided with a discharge tube containing a pair of electrodes therein and being filled with mercury, an inert gas and a halogen gas, the amount of the mercury filled being 0.12 to 0.35 mg/mm3, the halogen gas being at least one gas selected from the group consisting of Cl, Br and I and being present in an amount of 10−7 to 10−2 μmol/mm3, and the electrodes being mainly composed of tungsten, and the tungsten as a material of the electrodes contains not more than 12 ppm of potassium oxide (K2O). In such a high pressure discharge lamp, blackening of the discharge tube due to the potassium oxide (K2O) contained in the tungsten, and decrease in illumination maintenance can be prevented, thus providing a high pressure discharge lamp with a long lifetime, a lighting optical apparatus using the high pressure discharge lamp as a light source, and an image display system using the lighting optical apparatus. In another aspect, the amount of —OH in the glass of the discharge tube is less than 3 ppm. In a further aspect, the discharge lamp has a restriking voltage of less than 20 V.

摘要： A high-pressure mercury vapor discharge lamp comprises an arc tube in which a pair of electrodes are provided and in which a rare gas as a starting gas, a material from which a free halogen is to be produced during a lighting operation, and mercury are enclosed. The arc tube satisfies X/L≧88, in which X(W) is a lighting operation power and L (mm) is a distance between the electrodes. The high-pressure mercury vapor discharge lamp satisfies the following expression: 1.2≦&phgr;/(X×10−2+3.2)≦1.6 in which &phgr; (mm) is the inner diameter of the arc tube. Therefore, the high-pressure mercury vapor discharge lamp has a high luminance, a good emission spectrum, and a long life.
