  • Patent number: 7922334
    Abstract: A projector having optical components, a power source unit, and a light source unit. The projector is capable of lowering its internal temperature utilizing: a first, second, and third fan (41, 42, 43) provided near the optical components for introducing external air from outside the projector to cool the optical components; and a fourth, fifth, and sixth exhaust fan (16, 17, 18). The fourth fan (16) blows the air that was taken in by the first, second, and third fan (41, 42, 43) and has cooled the optical components, onto the light source unit to further cool the light source unit. The fifth and sixth exhaust fans (17, 18) discharge the air that has cooled the light source unit and power supply unit out of the projector.

  • Publication number: 20080246929
    Abstract: In a projection type image display apparatus, a noise removal filter portion 15 is separated from a power source unit body 14. The separated noise removal filter portion 15 is provided in the vicinity of a side wall of a housing on which a power source inlet is provided, and of the power source unit body 14, respectively. Specifically, the power source unit body 14 is provided along a side wall of a front face of the horizontally-long housing of the projection type image display apparatus and the noise removal filter portion 15 is provided in a position opposed to the power source unit body 14 in a side wall of the back face. As a result, even when a light source lamp has a higher output, the projection type image display apparatus can achieve reduced noise by an improved cooling capability and reduced cost enabled by an efficient Electro Magnetic Compatibility (EMC) measure and the like.

  • Publication number: 20080246925
    Abstract: A first exhaust fan 17 for mainly discharging exhaust air from a light source lamp 19 to exterior and a second exhaust fan 18 for mainly discharging exhaust air from parts other than the light source lamp 19 are arranged to be parallel to each other. An end of the exhaust fan 17 facing the other exhaust fan 18 is moved to the inner side and the one exhaust fan 17 is inclined to discharge air in an exhaust direction toward a direction along which air is discharged from the other exhaust fan 18. There is provided a cooling fan 16 that blows air to an interior air blow outlet 161 communicating with the interior of the light source lamp 19 and exterior air blow outlets 162 and 163 communicating with an outer surface to cool the light source lamp 19. The exterior air blow outlets 162 and 163 are deviated from the center of the outer surface of the light source lamp 19. The cooling fan 16 is used to allow the exhaust air used for cooling the light source lamp 19 to be discharged through the first exhaust fan 17.
