摘要： To increase the usage efficiency of the light of optical elements used in a projection display device, a polarizing conversion unit is provided. This polarizing conversion unit consists of a unit frame, two polarizing conversion element arrays, a light-shielding plate, a lens array, and clips. From the side of one open surface of the unit frame, the two polarizing conversion element arrays are inserted, and the light-shielding plate and the lens array are inserted from the side of the other open surface in this order. These optical elements are clamped by four clips from the two directions of up and down in a state of being stored in the unit frame. Since the clips are formed of an elastic body, the clips can be easily attached and detached, and the respective parts of the polarizing conversion unit can also be easily attached and detached to and from the unit frame. In addition, these optical elements may be sequentially inserted from the side of one open surface.

摘要： The invention provides a light source device which can positively arrange a light source lamp at a predetermined position on an optical axis. To this end, the invention provides an alignment reference surface on a reflector to which the light source lamp is attached. More specifically, a light source device of the invention comprises a light source lamp, and a reflector for reflecting light emitted from the light source lamp, the light source lamp being attached to the reflector, wherein an alignment reference surface for aligning and mounting the light source lamp is formed on the reflector. According to the invention, the light source device can be assembled by mounting the light source lamp apart from the alignment reference surface by a predetermined distance with respect to, for example, the X-axis, Y-axis, and Z-axis, respectively. That is, in mounting the light source lamp to the reflector, it is possible to assemble the light source device without fine adjustment of the mounting position of the light source lamp while the light source lamp is lit.

摘要： A projection display device projector capable of improving cooling efficiency of the power unit includes a light source lamp unit, a projection lens unit, an exhaust fan provided near the light source lamp unit for ventilating an outer case, and a ventilating path provided inside the power unit. A suction fan is provided at the inlet of the ventilating path which is connected to the cooling air intake port through a duct cover to directly conduct fresh air into the ventilating path. Because the interior of the power unit is cooled by fresh air which is cooler than the air inside the outer case, cooling efficiency is enhanced.

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： The present invention provides a projector that surely reduces or prevents the deformation of a lens cap even when the cap is placed on a projection lens while a lamp is on, without powering off the lamp. A projector according to the invention includes a lamp, liquid crystal panels that modulate light from the lamp, a projection lens that projects the modulated light, a lens cap that protects the projection lens, a detector that detects the lens cap on the projection lens, and a projected display controller that controls the liquid crystal panels so as to block or reduce the light from the lamp if the lens cap is found to be detected based on a signal from the detector.
