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 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： 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： In a projection display device, a main board that is substantially perpendicular to a plane defined by optical axes of an optical unit is allowed to stand aside the optical unit. Therefore, if the main board is designed to have a small vertical size, the vertical size, i.e., the thickness of the projection display device, can be reduced. Therefore, unlike the conventional projection display device in which the main board is disposed above the optical unit, the entire device can be reliably reduced in thickness and size regardless of the thickness of the main board.

摘要： A projector is provided which is able to facilitate a reduction in size. The projector includes of a lamp information carrier circuit board and a lamp information detection circuit board, and a fuse for determining use and nonuse of a light source lamp. The lamp information carrier circuit board is stacked so as not to overlap the lamp information detection circuit board. For this reason, the lamp information carrier circuit board and the lamp information detection circuit board are stacked close to each other, and the space between the lamp information carrier circuit board and the lamp information detection circuit board can be narrowed.
