  • Patent number: 8104902
    Abstract: In a projection 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 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 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.

  • 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.
