Patent number: 10151441Abstract: A light emitting device includes a planar light emitting body configured to emit light in a planar shape, and a transparent member configured to control the light from the planar light emitting body. The transparent member has a light incidence surface arranged so as to face a light emitting surface of the planar light emitting body and configured to cause the light from the planar light emitting body to be incident on the transparent member and a light emission surface configured to emit, to the outside, the light which is propagated in the transparent member. The transparent member is formed so as to extend in a predetermined direction and formed such that a distance between the light incidence surface and the light emission surface changes in accordance with a position in the predetermined direction.Type: GrantFiled: September 30, 2015Date of Patent: December 11, 2018Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Toru Ito, Masaya Shido, Takayuki Otsubo

Patent number: 9967981Abstract: Provided is a light source unit including a base unit formed on a front surface thereof with a first circuit pattern by irradiating laser light to a resin molded article, and a light emitting element mounted on the base unit and electrically connected to the first circuit pattern. The base unit includes a mounting surface portion directed in a prescribed direction such that the light emitting element is mounted thereon, and a sidewall surface portion connected to the mounting surface portion in a plane intersection state, and the sidewall surface portion is formed as an inclined surface intersecting with the mounting surface portion at an obtuse angle.Type: GrantFiled: January 19, 2016Date of Patent: May 8, 2018Assignee: Koito Manufacturing Co., Ltd.Inventors: Yoshiaki Aiso, Koji Uchino, Hiromi Nakamura, Takayuki Otsubo

Patent number: 9739437Abstract: A vehicular lamp unit has a substrate, a light source having a first light-emitting element and a second light-emitting element disposed on the substrate, and an optical element having the light source attached thereto. The substrate is long in a first direction. The optical element radiates emitted light of the first and second light-emitting elements toward a front of the vehicular lamp unit, with a desired light distribution. A reference portion serving as a positioning reference for the optical element is provided in a part of the substrate. The first and second light-emitting elements are arranged in the first direction. The first light-emitting element illuminates an area having high light intensity of the light distribution. The second light-emitting element illuminates an area having low light intensity of the light distribution. The first light-emitting element is mounted at a position closer to the reference portion in the first direction than the second light-emitting element.Type: GrantFiled: September 5, 2014Date of Patent: August 22, 2017Assignee: KOITO MANUFACTURING CO., LTD.Inventor: Takayuki Otsubo

Patent number: 9644809Abstract: A light source unit includes a socket, a heat dissipation member, a board and a semiconductor light emitting element. The socket has a first thermal conductivity and includes a portion that defines a first side and a second side. The heat dissipation member has a second thermal conductivity being higher than the first thermal conductivity. The board is disposed on the first side. The semiconductor light emitting element is supported by the board. The socket is an injection-molded member. The heat dissipation member includes a first portion and a second portion. The first portion is disposed on the first side, extends in a first direction, and supports the board. The second portion includes a portion extending in a second direction intersecting with the first direction, as a result of being subjected to bending processing. A part of the second portion is disposed on the second side.Type: GrantFiled: January 28, 2015Date of Patent: May 9, 2017Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Ryujiro Ikuta, Takayuki Otsubo, Atsushi Ozawa, Takuya Serita
