摘要： A high-pressure discharge lamp lighting device is used for projector devices that allow controlling the mean electric power at a desired value with a slow processing speed. A color wheel rotates and disperses the beam from lamp into each of the color components, such that the electric power supplied to the lamp is controlled at different levels for each segment of the color wheel and the power feeding device control part finds the mean electric power by sampling the electric power supplied.

摘要： 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.

摘要： 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.
