摘要： A plurality of light source sections each have a reflector and a light source that is a discharge lamp. The plurality of light source sections are in a positional relationship wherein all reflector center axes are orthogonal to each other and at least one reflector center axis is orthogonal to the optical axis of a projection optical system. Interchange means interchanges the locations of the plurality of light source sections when a light source section needs to be replaced. Reflection means guides, to a converging optical system, light from that light source section whose reflector center axis is perpendicular to the direction of gravity.

摘要： The present invention includes: a rolled filter stretched between first and second winding shafts and, unused part of the filter being wound around the second winding shaft; a brush provided between the first and the second winding shafts so as to come into contact with a surface of the filter; a feeding mechanism for driving the first and the second winding shafts to take up or rewind the filter; and a feeding control unit for controlling the feeding mechanism. When activating a renewing operation for feeding unused part of the filter from the second winding shaft, the feeding control unit controls the feeding mechanism such that once the filter is taken up by the first winding shaft by an take-up amount La, the filter is rewound by the second winding shaft by a rewind amount Lb, and La and Lb satisfy a relationship La≧Lb. Without increasing the amount of the filter or the size of the device itself, the present invention can deliver adequate performance even in a dusty environment by a small number of filter renewing operations.

摘要： Randomly polarized light from a light source (106) enters a polarization separation section (103) through an integrator optical system (102) including a second lens plate (110) designed to have variant apertures. The polarization separation section (103) separates the incident light into two polarized lights whose polarization directions are orthogonal to each other. Then, the polarization directions of these polarized lights are aligned by a polarization conversion section (104). Thus, a polarized-light illumination unit in which polarization directions of randomly polarized light is converted into a desired polarization direction and at the same time the spread of illumination light can be suppressed can be obtained. Such a polarized-light illumination unit can be used suitably as an illumination unit for a projection-type image display unit using a liquid crystal light valve for modulating light by utilizing polarization and enables both the reduction in cost and the increase in luminance in the projection-type image display unit.
