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： In a projection display provided with an optical unit, a power source unit, an external case to store the optical unit and the power source unit, a suction opening (75) is formed in one end part of the power source unit, a discharge opening (77) is formed in the other end part, and the suction opening (75) is arranged in the vicinity of an air inlet in the external case. Because the suction opening (75) and the discharge opening (77) are provided, the inside of the power source unit can be independently and efficiently cooled, and the optical unit and the power source unit can be arranged closely to each other.

摘要： A projector is provided which can project a high quality image unaffected by dust, or the like, scattered in the projector by preventing the temperature of light-modulating elements from rising. Light transmissive plates are adhered to the light emitting surface of a liquid crystal panel for red light and the light emitting surface of a liquid crystal panel for green light. The amount of heat transmitted from the polarizing plates, which generate the heat, to the liquid crystal panels is reduced by the light transmissive plates. In addition, dust, scattered in the projector, does not stick onto the light emitting surfaces of the liquid crystal panels. In contrast, a light transmissive plate is not provided at the light emitting surface of liquid crystal panel for blue light having a high energy value per unit quantity of light. Thus, the problem of a light transmissive plate preventing heat dissipation at the liquid crystal panel is eliminated, so that efficient cooling can be achieved. The relative luminosity factor of blue light B is low, so that dust is not noticeable on the screen even when it sticks onto the light emitting surface of the liquid crystal panel.
摘要翻译：提供一种可以通过防止调光元件的温度升高而投影散射在投影仪中的灰尘等不受影响的高质量图像的投影仪。透光板粘附到用于红光的液晶面板的发光面和用于绿光的液晶面板的发光面。通过透光板减少从产生热量的偏振片传递到液晶面板的热量。此外，散射在投影仪中的灰尘不粘附到液晶面板的发光表面上。相反，在每单位光量具有高能量值的蓝色光的液晶面板的发光面上不设置透光性板。因此，消除了防止液晶面板散热的透光板的问题，从而可以实现有效的冷却。蓝光B的相对亮度因子低，即使粘在液晶面板的发光面上也不会在屏幕上显示灰尘。

摘要： Liquid crystal modulation elements are arranged so that light outgoing surfaces thereof face light incident surfaces of a color synthesizing prism. Transparent plates are bonded to the light outgoing surfaces of the liquid crystal modulation elements. For this reason, adhesion of dust to the light outgoing surfaces of the liquid crystal modulation elements can be prevented. Further, it is possible to prevent light reflection at the interface surface between the light outgoing surfaces and air due to the difference in refractive index therebetween. This allows a high-quality image to be projected without deteriorating the switching characteristic of the liquid crystal modulation elements while preventing dust from adhering to the light outgoing surfaces of the liquid crystal modulation elements.

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.
