Publication number: 20120127740Abstract: According to one embodiment, a luminaire includes a luminaire body, a socket, and a radiating member. The luminaire body has a cylindrical body part, and a lamp unit is housed within the body part. The luminaire body is inserted, from an upper side of the body part, into an embedding hole provided in an installation target section, and the luminaire body is thus arranged on the installation target section. The socket is arranged within the body part of the luminaire body, and the lamp unit is loaded therein. The radiating member is arranged on the upper side of the body part of the luminaire body and is formed with a smaller dimension than a maximum outer dimension of the body part of the luminaire body. The lamp unit loaded in the socket contacts the radiating member.Type: ApplicationFiled: November 17, 2011Publication date: May 24, 2012Applicant: TOSHIBA LIGHTING & TECHNOLOGY CORPORATIONInventor: Toshifumi MASUDA

Publication number: 20120127741Abstract: According to one embodiment, a lamp unit includes a light-emitting module, a housing, a lighting circuit, and a heat conductive sheet. The light-emitting module includes a light emitting portion having a semiconductor light-emitting element formed thereon. The housing includes a case opening in the direction of irradiation of light, and a base on a side of the case opposite from the direction of irradiation of the light. The light-emitting module is mounted on a surface of the base on the case side. A base surface is formed on an outer surface of the base on the side opposite from the case side, and a depressed portion is formed on the base surface. The lighting circuit is accommodated in the housing. The heat conductive sheet allows resilient deformation, and is disposed in the depressed portion.Type: ApplicationFiled: November 17, 2011Publication date: May 24, 2012Applicant: TOSHIBA LIGHTING & TECHNOLOGY CORPORATIONInventors: Takeshi Osada, Yuichiro Takahara, Shigeru Osawa, Toshifumi Masuda, Hiromichi Nakajima
