摘要： A projector includes a first lens plate having a plurality of lenses, a second lens plate having a plurality of lenses, a light valve that modulates an output light beam from the second lens plate, and a light source apparatus. The light-source apparatus has a light-source lamp including an emission tube, a reflective mirror that reflects a divergent light beam from the light-source lamp to output a parallel light beam, the reflecting mirror having a reflective surface, a lamp housing that supports the reflective mirror, and an electrode lead. The electrode lead is led out of an end of the emission tube that is projected forward out of the reflective surface and is connected to an external connection terminal board which is positioned to a rear side of the reflective surface. The electrode lead is routed via the portion of the reflective mirror other than an effective area of the reflective mirror. A portion of the electrode lead positioned on the side of the reflective surface is arranged along a grove of a lens of the plurality of lenses of one of the first and second lens plate.

摘要： A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

摘要： A light-source lamp unit 100 includes a light-source lamp unit 1 detachably mounted, and CPU 101 constituting drive and control means for the light-source lamp unit. CPU 101 senses the lamp information borne by lamp-information storing block 5 in the light-source lamp unit 1, about a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. CPU 101 compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, CPU 101 gives a warning display at a time that is earlier than the life expiration of the lamp by a fixed duration of time, to warn that a lamp replacement is needed. Since the lamp-information storing block 5 in the light-source lamp unit 1 stores the information about the lamp type and characteristics of the lamp, the light-source device 100 can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

摘要： At least one of four rectangular prisms in a dichroic prism is made longer than the other rectangular prisms. Parts of the rectangular surfaces of the long rectangular prisms partially protrude from the rectangular surfaces of the other rectangular prisms in the longitudinal direction. The protruding parts of the rectangular surfaces of the long rectangular prisms are not provided with a dichroic film. Such a construction makes it possible to prevent return light, which returns from the light emitting surface side of the dichroic prism and the dichroic prism, from emitting again from the light emitting surface.

摘要： Two polarization conversion element arrays are disclosed. Each polarization conversion element array is composed of a plurality of polarization conversion elements for converting light incident upon the polarization conversion element array to a linearly polarized light beam with a predetermined polarization direction. The plurality of polarization conversion elements are disposed opposite to each other with a predetermined space provided between at about the center of the light-outgoing surface of a lens array in the direction of arrangement. Of the light beams (s-polarized+p-polarized light beams) gathered by the lens array, light beam that is not incident upon the polarization conversion element and passes through the predetermined space is a light beam including a predetermined polarized light beam (s-polarized light beam) that is primarily made to leave the array 320a and an ineffective polarized light beam (p-polarized light beam). Of the light passing through and leaving the space, the required polarized light beam alone can be made to leave as an effective light beam by providing a polarization plate or the like at the light-outgoing side of the space.

摘要： A technique for preventing a decrease in the amount of effective polarized light that emerges from a polarizing conversion element array is provided. To this end, a polarizing illumination device includes a polarizing conversion element array that converts light emitted from a light source into one type of linearly polarized light, and a plurality of light-shielding portions for blocking a part of light that is incident on the polarizing conversion element array. The polarizing conversion element array is divided into effective incident areas for emitting effective polarized light, and ineffective incident areas for emitting ineffective polarized light. The widths of the plurality of light-shielding portions are set to be smaller than the width of the ineffective incident areas of the polarizing conversion element array, so that light to be incident on the effective incident areas is not blocked. This makes it possible to prevent a decrease in the amount of effective polarized light that emerges from the polarizing conversion element array.
