摘要： An illumination apparatus includes: first and second lamps; and a combining mirror configured to combine emitted lights from the first and second lamps The combining mirror includes first and second reflection surfaces opposing the first and second lamps respectively, being abutted vertically with respect to each other, whereby forming an edge. Since optical axes of the first and second lamp are respectively inclined with respect to a reference axis being orthogonal to a system optical axis of the illumination apparatus, central axes of the lights from the first and second lamps are incident on a downstream optical system in a state of being slightly inclined with respect to the system optical axis after being reflected on the first and second reflection surfaces respectively.
摘要翻译：照明装置包括：第一和第二灯; 以及组合镜，其被配置为组合来自第一和第二灯的发射光。组合镜包括分别与第一和第二灯相对的第一和第二反射表面，其相对于彼此垂直抵接，由此形成边缘。由于第一灯和第二灯的光轴分别相对于与照明装置的系统光轴正交的基准轴倾斜，所以来自第一和第二灯的光的中心轴入射在下游光学系统中在分别在第一和第二反射面上反射之后相对于系统光轴稍微倾斜的状态。

摘要： A projector can form images of illumination system on respective optical paths at positions of corresponding liquid crystal display panels with respect to a light emission surface of a cross dichroic prism without relatively inverting the images and without increasing the number of lenses from the number of lenses included in a relay optical path structure in related art. Moreover, the projector can equalize the magnification of the images formed on the respective liquid crystal display panels by controlling relative image-forming conditions of the first and second optical paths in advance. Thus, deterioration of white balance and color unevenness of light projected by the projector can be reduced even when light emission distribution of a light source varies with elapse of time, for example.

摘要： A dimmer includes a pair of pivoting sections provided across an optical axis of a light beam and having pivot axes and a pair of light blocking sections held by the pair of pivoting sections and configured to pivot following pivoting of the pivoting sections to block the light beam. In a maximum light blocking state, positions in the optical axis direction of opposed ends on the optical axis side of the pair of light blocking sections are different from each other. In the maximum light blocking state, the opposed ends on the optical axis side of the pair of light blocking sections are arranged to overlap each other in a direction along the optical axis.

The two light source devices are disposed in such positions that the respective light source optical axes of the two light source devices are substantially perpendicular to the projection optical axis of the projection system. The reflection system is constructed such that the center axes of the respective illumination lights emitted from the two light source devices and entering the converging lens are inclined toward the illumination optical axis of the lighting device by a predetermined angle.
