Patent number: 5718503Abstract: An illumination apparatus is disclosed which efficiently irradiates an irradiation surface without destroying the symmetry of an illuminance distribution at the irradiation surface. A light source is displaced from a center of curvature of a spherical mirror in a direction in a displacement plane which includes an axis of symmetry of the spherical mirror so as to form a light source image at a position off the light source. Due to this, a ray from the spherical mirror passes off the light source (i.e., the position of the light source image), and therefore, a reflection ray is not shielded, absorbed nor otherwise disturbed by the light source, which in turn prevents deterioration in the efficiency of utilization of light.Type: GrantFiled: June 5, 1995Date of Patent: February 17, 1998Assignee: Dainippon Screen Manufacturing Co., Ltd.Inventors: Masahiko Kokubo, Kenji Ueyama, Kenji Endo

Patent number: 5414551Abstract: An afocal optical system is formed by a paraboroid mirror and an optical element having a stereographic projection characteristics which is defined by the following equation:hi'=2.multidot.f.multidot.tan (.theta.i/2)where hi' is a height of a light beam, leaving the optical element, taken from the optical axis or a heigh of an image taken from the optical axis, f is a focal length of the optical element and .theta.i is an angle of incidence with respect to the optical element. The focal point of the optical element coincide with that of the first paraboroid mirror. Thus, a compact afocal optical system which satisfies hi'=m.multidot.hi is manufactured at low costs.Type: GrantFiled: August 16, 1994Date of Patent: May 9, 1995Assignee: Dainippon Screen Mfg.
