Patent number: 9163790Abstract: An illumination device and a light-emission module suppressing a change in color temperature when light emitted from a light-emission unit passes through an optical member. The illumination device has a lighting apparatus that includes: a first light-emission part emitting light of a daylight color temperature; a second light-emission part emitting light of an incandescent lamp color temperature; and the optical member, which is disposed on an optical path of the light emitted from the light-emission parts. A correlated color temperature of the light emitted from the second light-emission part is set to 2238 K. Due to this, in a spectrum of the light emitted from the second light-emission part, a maximum intensity within a wavelength range from 400 nm to 500 nm is no greater than one-tenth of a maximum intensity within a wavelength range from 300 nm to 800 nm.Type: GrantFiled: December 19, 2013Date of Patent: October 20, 2015Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Toshifumi Ogata, Atsuyoshi Ishimori, Masumi Abe, Hiroshi Yamaguchi, Yasufumi Wada

Publication number: 20150214451Abstract: Each of a plurality of semiconductor light-emitting element has, on an upper surface thereof that has a quadrilateral shape, a pair of connecting portions having different polarities from each other. The pair of connecting portions are aligned on a diagonal of the quadrilateral shape. The diagonal intersects a row direction along which the semiconductor light-emitting elements within a row are arranged. Connecting portions having identical polarity are positioned on an imaginary line parallel to the row direction. Metal wires intersect two sides extending from a corner, on the diagonal, of the upper surface of each of the semiconductor light-emitting elements when viewed from a direction perpendicular to a mounting surface of a substrate for mounting the semiconductor light-emitting elements.Type: ApplicationFiled: September 4, 2013Publication date: July 30, 2015Inventors: Masumi Abe, Yasufumi Wada, Toshifumi Ogata, Kenji Sugiura

Publication number: 20150098225Abstract: A lighting apparatus includes a substrate, a light-emitting element, and a sealing member. The light-emitting element emits light in a first wavelength range. The sealing member contains a material that converts the light in the first wavelength range to light in a second wavelength range different from the first wavelength range. The sealing member has a curved convex contour in at least one cross section that passes through the center of the light-emitting element and is perpendicular to a principal surface of the substrate. A curved line indicating a change in output angle that occurs upon a change in observation angle is approximated by a quadratic or trigonometric function that passes through the origin.Type: ApplicationFiled: October 7, 2014Publication date: April 9, 2015Applicant: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masumi ABE, Toshifumi OGATA, Atsuyoshi ISHIMORI, Kenji SUGIURA, Yasufumi WADA

Publication number: 20150049480Abstract: A light-emitting module includes a substrate, and elongated light-emitting units arranged in rows on the substrate. Each light-emitting unit includes an element array of light-emitting elements arranged on the substrate and a sealing member sealing the element array. The sealing member contains a wavelength converting material. When the light-emitting units are viewed from a direction that is parallel to a surface on which the plurality of light-emitting units are arranged and coincides with a row direction being a direction along which the light-emitting units are arranged in rows, two of the light-emitting units are arranged such that portions of one of the two light-emitting units nearer to the center in the row direction are visible without being obstructed by the other light-emitting unit.Type: ApplicationFiled: October 16, 2012Publication date: February 19, 2015Applicant: PANASONIC CORPORATIONInventors: Toshifumi Ogata, Atsuyoshi Ishimori, Masumi Abe
