20100073637 | ILLUMINATING DEVICE AND PROJECTION DISPLAY DEVICE - An illuminating device includes a plurality of light source portions for emitting light, a plurality of optical fibers for allowing incidence of the light emitted from the respective light source portions, and a bundling portion for bundling exit ends of the optical fibers. The light source portions or the optical fibers are constructed in such a manner that a flexure of each of the optical fibers is suppressed to mount the each optical fiber in a state close to a straight state. For instance, the light source portions are arranged in an arc shape, with a distance of each of the light source portions with respect to the bundling portion being set as the radius of the arc shape. In this arrangement the respective optical fibers are set to have lengths substantially equal to each other. | 03-25-2010 |
20100182573 | ILLUMINATING DEVICE AND PROJECTION DISPLAY DEVICE - An illuminating device includes a plurality of light source portions having a light source and condenser optics for condensing light from the light source, a plurality of optical fibers each connected to a corresponding one of the light source portions and into which the light from the corresponding condenser optics is incident, and a bundling portion for bundling the plurality of optical fibers. The plurality of light source portions are arranged on a plane approximately parallel to a bundling-central axis of the bundling portion, and the farther the light source portion is arranged from the bundling portion, the more the optical axis of the condenser optics is tilted toward the bundling portion from a direction vertical to the plane. | 07-22-2010 |
20100245781 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a solid light source, a light valve configured to modulate light emitted from the solid light source, and a projection unit configured to project light emitted from the light valve on a projection plane. The projection display apparatus includes a cable terminal provided on at least one of sidewalls forming both ends of the housing case in a horizontal direction parallel to the projection plane. | 09-30-2010 |
20100245787 | PROJECTION DISPLAY APPARATUS - A projection display apparatus includes a housing case housing a light source unit, a light valve, a projection unit, and a cooling unit. A size of the housing case in an orthogonal direction to a projection plane is smaller than a size of the housing case in a horizontal direction parallel to the projection plane. The projection unit is arranged at substantially center of the housing case in the horizontal direction parallel to the projection plane. | 09-30-2010 |
