    摘要： A projection display device 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.

The first exposed side is formed on one edge of the affixed side of the first triangular prism. Similarly, the second triangular prism and the fourth triangular prism are attached to each other such that there is a second step difference on the same edge, and a second exposed side is formed on one edge of the affixed surface of the second triangular prism. Further, the first and the third triangular prisms and the second and the fourth triangular prisms are attached, with a step difference between them, in such a way that the aforementioned first exposed side and the aforementioned second exposed side are located on the edges facing the same direction; and a third exposed surface that is orthogonal to the aforementioned first and second exposed surfaces is formed between the aforementioned first triangular prism and the aforementioned second triangular prism.

    摘要： A power supply unit is formed so as to be divided into first and second power supply blocks, which are disposed on both sides of a projecting lens. This allows the power supply blocks to be efficiently disposed in a projection display device, so that dead space is not easily formed in the projection display device, making it possible to reduce the size of the projection display device. First and second power supply block cooling paths are formed at first and second power supply blocks which are liable to generate heat, respectively. A light modulating system cooling path is formed at a light modulating system disposed at substantially the center of the projection display device. Therefore, even when these component parts are closely disposed in the projection display device of a compact size, proper cooling operations can be carried out, making it possible to cool the entire projection display device more efficiently.

    摘要翻译： 电源单元被形成为被分成设置在投影透镜两侧的第一和第二电源块。 这使得电源块能够有效地设置在投影显示装置中，使得在投影显示装置中不容易形成死区，从而可以减小投影显示装置的尺寸。 第一和第二电源块冷却路径分别形成在易于产生热量的第一和第二电源块处。 光调制系统冷却路径形成在设置在投影显示装置的大致中心的光调制系统。 因此，即使这些部件紧密地配置在小型的投影型显示装置中，也能够进行适当的冷却运转，能够更有效地冷却投影显示装置整体。
