摘要： In a lamp assembly according to the present invention, a double ended lamp is securely supported in such a way that the one end of said lamp is fixed to a cap or a mirror and the other end of said lamp is fixed to a power supply member. The power supply member located in front of the mirror is made of a metal member of a higher rigidity. A flexible covered wire is secured with an adhesive, so that it may be located outside the periphery of the mirror and a connection portion of the metal member to the covered wire cannot protrude from a contour of the edge of the mirror. Therefore, the lamp assembly can be easily handled. In addition, the inclined bottom surface of a ventilating cutout in a cap ensures that the lamp can be cooled satisfactorily, leading to a long life of the lamp.

摘要： A metal halide lamp in which the radiant efficiency is not adversely affected, in which outstanding color reproducibility is obtained, and which is suitable for a light source of an OHP or a direct projector is achieved, according to the invention, by the fact that, within an arc tube provided with a pair of electrodes, together with mercury and a starting rare gas, halides of dysprosium (Dy), yttrium (Y) and cesium (Cs) are encapsulated with the molar ratio of the encapsulated metals Dy to Y is being fixed in the range of 0.3.ltoreq.Dy/Y.ltoreq.1.0. In this way the green portion to which there is a sensitive visual reaction is reduced, the blue portion increased, and thus the color reproducibility is increased.

摘要： To avoid the phenomenon of unsightly flickering in images projected by the projector, in high pressure discharge lamps—especially in high intensity discharge lamps, such as high pressure mercury lamps, metal halide lamps, and xenon lamps—that are used in projectors, even in the presence of the phenomenon of cyclical modulation of the lamp voltage by the returning the light spectrum when the light reflected by the dynamic color filter returns back through the optical system to the lamp, at least during steady operation of the discharge lamp (Ld), a target lamp current signal generation circuit (Up) acquires multiple lamp voltage detection signal (Sv) over a period that is at least as long as the color order cycle of the dynamic color filter (Of) and generates a target lamp current signal (St) based on the multiple lamp voltage detection signals (Sv) that were acquired.
