Patent number: 10270944Abstract: An image capturing device (1) includes: a microlens array (33) including a plurality of micro condenser lenses (34) arranged at a focal position of an imaging optical system for forming a plurality of erect equal-magnification images; and an imaging unit (31) including light-sensitive pixels (32x) provided at positions corresponding to the micro condenser lenses 34. Micro condenser lenses (34) have refractive powers to condense, among light rays incident from the imaging optical system, light rays incident at an incident angle within a predetermined limited angle range, onto positions different from positions on which light rays incident at an incident angle outside the limited angle range are incident. Effective light-sensitive regions of the light-sensitive pixels (32x) receive only light rays incident at an incident angle within the limited angle range among light rays entered micro condenser lenses (32).Type: GrantFiled: February 28, 2017Date of Patent: April 23, 2019Assignee: Mitsubishi Electric CorporationInventors: Hiroyuki Kawano, Kosaku Yamagata, Tadashi Minobe, Tatsuya Kunieda, Masatoshi Kodama

Patent number: 9167121Abstract: A lighting unit is provided with: LED arrays in which light-emitting elements are positioned in an array in a main scanning direction; cylindrical parabolic mirrors that project light emitted from the LED arrays on an illumination region of an illuminated item; and a housing that houses or holds the LED arrays and the cylindrical parabolic mirrors. Each cylindrical parabolic mirror forms a shape in which a cylindrical paraboloid having curvature with respect to a sub-scanning direction has been clipped by an axial plane that is perpendicular to the vertex of the cylindrical paraboloid in the main scanning direction. The LED arrays are positioned so as to include the focal position of the cylindrical paraboloid in the light-emitting region, the central axis in the light-emitting direction being perpendicular to the axial plane.Type: GrantFiled: October 24, 2012Date of Patent: October 20, 2015Assignee: Mitsubishi Electric CorporationInventors: Tatsuki Okamoto, Taku Matsuzawa, Tadashi Minobe, Takahito Nakanishi

Patent number: 8982430Abstract: A lighting unit includes LED chips positioned in an array form in a main scanning direction on LED substrates. Cylindrical parabolic mirrors each form a shape in which a cylindrical paraboloid having curvature with respect to an sub-scanning direction has been clipped by an axial plane that is perpendicular to the vertex of the cylindrical paraboloid in the main scanning direction, and project light emitted from the light source on an illumination area of an illuminated item. Each cylindrical parabolic mirror includes an anchoring section that is provided at the vertex of the cylindrical paraboloid, and extends from the vertex in an outside direction of the cylindrical paraboloid. Heat-radiating plates each have a contact section that is in contact with the LED substrate, and a non-contact section. Each LED substrate is interposed between the contact section of the heat-radiating plate and the anchoring section of the cylindrical parabolic mirror.Type: GrantFiled: October 24, 2012Date of Patent: March 17, 2015Assignee: Mitsubishi Electric CorporationInventors: Tatsuki Okamoto, Taku Matsuzawa, Tadashi Minobe, Takahito Nakanishi
