Patent number: 9353927Abstract: A lighting apparatus according to an embodiment includes an optical unit and a body. The Optical unit includes a light emitting module that has a light emitting element, a reflector that controls distribution of light from the light emitting module, and a unit supporting member that supports the light emitting module and the reflector. A plurality of optical units are mounted to the apparatus body such that each optical unit is detachable. And the body includes an irradiating portion that has an opening through which the optical units irradiate light.Type: GrantFiled: July 21, 2014Date of Patent: May 31, 2016Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Toshiyuki Ishida, Akimichi Takahashi, Hirokazu Yamada, Makoto Kawagoe, Hiroyuki Kuramochi

Patent number: 8901848Abstract: The present invention comprises a lighting apparatus main body having a reflecting surface, a main light source arranged in the reflecting surface of the lighting apparatus main body, a sub-light source which is arranged at the lighting apparatus main body and illuminates the neighborhood of the main light source directly, and a control circuit which controls the main light source and the sub-light source. Since the lighting apparatus illuminates downward with a direct illumination of the main light source and an indirect illumination of the sub-light source, the glare of the main light source is reduced.Type: GrantFiled: September 30, 2009Date of Patent: December 2, 2014Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Hiroaki Watanabe, Keiichi Shimizu, Kozo Ogawa, Erika Takenaka, Akimichi Takahashi, Shinji Nogi, Shinichi Kumashiro

Patent number: 8057072Abstract: A light-emitting module includes at least one light-emitting element provided on a mount surface of a substratum. A translucent member is provided so as to face the mount surface of the substratum. The translucent member is separated from the light-emitting element and contains a phosphor material that converts a wavelength of light emitted by the light-emitting element. A frame having heat conducting properties is interposed between the substratum and the translucent member. The frame surrounds the light-emitting element. The frame includes an opening that leads light emitted by the light-emitting element to the translucent member, and a heat conductor thermally connected to the translucent member. The heat conductor includes a heat radiator exposed outside of the translucent member.Type: GrantFiled: December 10, 2009Date of Patent: November 15, 2011Assignee: Toshiba Lighting & Technology CorporationInventors: Erika Takenaka, Kozo Ogawa, Keiichi Shimizu, Hiroaki Watanabe, Akimichi Takahashi, Shinji Nogi, Shinichi Kumashiro
