20110025218 | Mercury lamp and mercury lamp lighting apparatus - In an ultrahigh pressure mercury lamp that encloses mercury is enclosed in an arc tube, an electrode has a head portion whose diameter is larger than that of an axis portion and a cylindrical portion formed to project from and extend, integrally with a back end face of the head portion, wherein an inner circumference face the cylindrical portion is apart from the axis portion so as to surround the axis portion. During an alternating current lighting, a relational expression of d/(1/f)×1/2≧3.8 is satisfied, wherein a frequency, which relates to an anode operation period that is the longest in the anode operation period during which one electrode serves as an anode, is represented as f, and a distance in an axial direction from the leading edge position of the head portion of the electrode to a boundary position between the head portion and the cylindrical portion is represented as d. | 02-03-2011 |
20110221355 | Light source apparatus - In a light source apparatus, an alternating current is supplied to a high pressure discharge lamp from a power supply apparatus to light the lamp. The arrangement state of the lamp is detected by a detection circuit. When the lamp is horizontally arranged, electric energy, whose flow direction is from one electrode of the lamp to the other electrode, is set to be approximately the same as electric energy, whose flow direction is from the other electrode to the one electrode. When the lamp is vertically arranged, while a cycle, which is the same as a polarity change cycle in the horizontal arrangement, is maintained, electric energy, which flows from an upper electrode to a lower electrode, is set to be smaller than electric energy, which flows from the lower electrode to the upper electrode. | 09-15-2011 |
20110221356 | Light source apparatus - A first energy ratio A/B of a first alternating current of a steady frequency supplied to a lamp is set to a value C, when the lamp is horizontally placed. A second alternating current of a lower frequency, whose second energy ratio A/B is set to the value C, is inserted. When the lamp is vertically placed, a first energy ratio A′/B′ is set to the value C or a value D, which is smaller than the value C. A second ratio A′/B′ is set to the value D or a value E, which is lower than the value C. A and A′ each represents an energy that flows from a first electrode of a pair of electrodes of the lamp to a second electrode of the pair. B and B′ each represents an energy that flows from the second electrode to the first electrode. | 09-15-2011 |
