Patent number: 9194568Abstract: A lighting unit according to one embodiment includes a board, a support member, and a plurality of heat radiation fins. A light emitting element is disposed on a first surface of the board. The support member has an interior surface on which a second surface of the board that is opposite to the first surface is disposed to be in contact therewith to enable heat conduction from the board to the support member. The heat radiation fins are disposed on an exterior surface of the support member substantially parallel with each other and with a clearance between each other, and each having a flat shape that extends outwardly from the exterior surface.Type: GrantFiled: August 6, 2012Date of Patent: November 24, 2015Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Takayoshi Moriyama, Junya Murata, Makoto Yamazaki, Yumi Hanyuda, Katsumi Hisano, Mitsuaki Kato, Masataka Shiratsuchi, Yuichiro Yamamoto

Patent number: 8770798Abstract: According to one embodiment, a floodlight includes at least one light-emitting part, a thermal radiator, a reflector, and an adapter part attachable to and detachable from the thermal radiator. The light-emitting part includes an LED element. The thermal radiator is thermally connected to the light-emitting part. The reflector is provided on the thermal radiator, and controls luminous intensity distribution from the light-emitting part. The adapter part includes an extension reflector. The extension reflector is continuous with the reflector in a state where the adapter part is attached to the thermal radiator and, together with the reflector, controls the luminous intensity distribution from the light-emitting part to provide a luminous intensity distribution angle narrower than the reflector.Type: GrantFiled: January 30, 2013Date of Patent: July 8, 2014Assignee: Toshiba Lighting & Technology CorporationInventors: Ryotaro Matsuda, Yumi Hanyuda, Takayoshi Moriyama, Yoshiro Oka

Publication number: 20130250574Abstract: A lighting unit according to one embodiment includes a board, an insulating plate, an optical lens, and a positioning member. The board has a mounting surface on which a light emitting element is mounted. The insulating plate is disposed on the mounting surface of the board to control the reflection direction of light emitted from the light emitting element. The optical lens diverges or converges the light reflected by the insulating plate. The positioning member positions the insulating plate and the optical lens such that the insulating plate and the optical lens are located away from each other by a predetermined distance. A lighting device according to one embodiment includes a plurality of the lighting units fixed to the lighting device via a fixing frame.Type: ApplicationFiled: August 6, 2012Publication date: September 26, 2013Applicants: Kabushiki Kaisha Toshiba, Toshiba Lighting & Technology CorporationInventors: Takayoshi MORIYAMA, Junya MURATA, Makoto YAMAZAKI, Yumi HANYUDA, Katsumi HISANO, Mitsuaki KATO, Masataka SHIRATSUCHI, Yuichiro YAMAMOTO
