摘要： The invention concerns achieving an increase in illumination efficiency of an illumination optical system in a projector using an optical modulation device. A projector may include an optical modulation device for controlling a direction of emission of illumination light applied to a substantially rectangular light application surface, including a plurality of pixels, for each pixel according to image information to thereby emit image light representing an image, an illuminating optical system for emitting the illumination light so that the central axis of the illumination light applied to the light application surface enters the light application surface at a predetermined angle, and a projection optical system for projecting the image light emitted from the optical modulation device. The illuminating optical system may include a light source, and a light-transmitting rod through which the light emitted from the light source passes. At least a part of the light passes while being repeatedly reflected by an inner surface of the light-transmitting rod. The light-transmitting rod has a shape such that a sectional area perpendicular to the central axis of the light-transmitting rod monotonically increases from the incident side to the emitting side.

摘要： A projector of the type which uses an optical modulator that modulates light by controlling the emitting direction of light applied to a light illumination surface in accordance with image information is provided with a reduction in size. In the projector a prism has a selective reflection/transmission surface which reflects illumination light emitted from an illumination optical system and impinging thereupon, and causes the illumination light to impinge upon the light illumination surface of an optical modulator at a predetermined angle. The prism allows the modulated light emitted from the optical modulator to be transmitted therethrough and emits the light to the projection optical system. The selective reflection/transmission surface is formed such that when the optical path of the illumination light is projected onto a plane parallel to the light illumination surface, the inclination of the central axis of the illumination light emitted from the illumination optical system and impinging upon the selective reflection/transmission surface is different from the inclination of the central axis of the illumination light reflected by the selective reflection/transmission surface and impinging upon the light illumination surface.

摘要： The invention achieves a reduction in size of a projector by shortening a length of an optical path of an illuminating optical system in a projector using an emitting direction control-type optical modulation device as compared to that of a conventional illuminating optical system, and thus, improves the illumination efficiencies of the illuminating optical system. An illuminating optical system includes a light source, a first lens array having a plurality of first small lenses for dividing light emitted from the light source into a plurality of partial light beam fluxes, and a second lens array having a plurality of second small lenses corresponding to the plurality of first small lenses. In addition, the illuminating optical system includes an optical element such that an outline shape of an emitting surface is a quadrilateral having first and second diagonal lines of different lengths. The quadrilateral of the optical element is set so that the ratio of two diagonal lines of a quadrilateral illumination region to which the illumination light is applied comes closer to 1 than the ratio of the lengths of the first and second diagonal lines.

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： A polarizing illumination device and a projection display device using the polarizing illumination device improve light utilization efficiency. Polarizing conversion elements are placed so that one of polarizing separation films of a first polarizing conversion element and one of polarizing separation films of a second polarizing conversion element are close to each other and so that effective incident areas and ineffective incident areas are alternately arranged in the x direction. The width WP in the x direction of the effective incident areas and the ineffective incident areas is set to be larger than half of the width WL in the x direction of small lenses in a second lens array. The optical axes of each of small lenses are offset from the lens centers thereof so that partial beams emerging from the small lenses in a first lens array optimally enter the effective incident areas where the partial beams should enter.
