摘要： A light source device has a plurality of semiconductor lasers, in which deterioration in the luminous efficiency of the phosphor can be reduced. In the condensing region, a condensing point shape (beam shape) with a desired size and aspect ratio can be obtained. The light source device and a projector employing the light source device can be provided with a low manufacturing cost. A light source device 1 includes a plurality of light sources 10A, 10B, having semiconductor lasers 12A, 12B and a collimating lens 13, a condensing lens 20 to condense light from the light sources 10A, 10B, an optical component 70 arranged between the light sources 10A, 10B and the condensing lens 20 and configured to allow light from the light sources to pass therethrough, and a phosphor wheel 30 having phosphors 32 and configured to allow light condensed by the condensing lens 20 to pass therethrough. The optical component 70 has an inclined optical surface 74 that inclines from the plane perpendicular to the optical axis of the collimating lens 13, and the inclined optical surface has different inclination angles for each of the light sources 10A, 10B. Some of the semiconductor lasers 12A, 12B are first semiconductor lasers 12A having a short axis of the shape of its condensing spot aligned in a first direction and some of the semiconductor lasers are second semiconductor lasers 12B having a short axis of the shape of its condensing spot aligned in a second direction that is different from the first direction. A light diffusing layer is arranged in the optical path of the emitting light of either the first semiconductor laser 12A or the second semiconductor laser 12B. A light scattering layer 72 is arranged in the optical path of the emitting light of either the first semiconductor laser 12A or the second semiconductor laser 12B. A projector includes the light source device 1.

摘要： A small projection type display unit capable of preventing the overlapping of the optical path of an incident light on that of an outgoing light in a reflection type light bulb and providing high-picture-quality projection images, and a rear projector and a multi-vision system using it. The projection type display unit comprises an illuminating optical system (2) for collecting light emitted from a light source (1) to form an illuminating light, a reflection type light bulb (6) for reflecting an illuminating light and outputting a modulation light that forms an optical image, a projection lens (7) for projecting an optical image formed by the reflection type light bulb, and a positive-power lens element (5). The lens element (5) is formed of one planoconvex lens and is disposed between the reflection type light bulb and the projection lens so that, with the convex surface directed toward the projection lens, an illuminating light passes through the lens element to illuminate the reflection type light bulb, and a modulation light output from the reflection type light bulb passes through the lens element to beam onto the projection lens.
