Patent number: 8393765Abstract: A luminaire includes a light-emitting unit, a main body frame, a support frame, and a lighting unit. The light-emitting unit mounts light-emitting elements. The main body frame supports the light-emitting unit, and is formed rectangular having a hook-shaped engaging piece on one side. The support frame is formed rectangular surrounding the outer periphery of the main body frame, and has a groove-shaped receiving place to engage with the engaging piece of the main body frame, on one internal side. The lighting unit turns on the light-emitting elements.Type: GrantFiled: December 3, 2009Date of Patent: March 12, 2013Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Naoki Sugishita, Homare Takai, Takafumi Oishi, Yasuhiko Ishii, Masanao Hieda, Yutaka Hashimoto
