Patent number: 9506632Abstract: 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: GrantFiled: October 16, 2012Date of Patent: November 29, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Toshifumi Ogata, Atsuyoshi Ishimori, Masumi Abe

Patent number: 9435512Abstract: 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: GrantFiled: October 7, 2014Date of Patent: September 6, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masumi Abe, Toshifumi Ogata, Atsuyoshi Ishimori, Kenji Sugiura, Yasufumi Wada

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
