Publication number: 20100073949Abstract: Light of an incorporated lamp illuminates the lower side of a side surface of a door of a vehicle. A rear end part of a lamp socket mounted with the lamp is exposed from a cylinder part of a lamp housing and projected from the lamp housing toward a holder/mirror assembly. Therefore, when replacing the lamp, the lamp socket can be found easily by simply removing the holder/mirror assembly, and the lamp can easily be extracted along with the lamp socket, to an operator side. Also, when attaching the lamp socket, high visibility of an opening part can be obtained because the opening part of the cylinder part is exposed to the holder/mirror assembly side in the lamp housing, thereby achieving a door mirror with extremely good workability of lamp replacement.Type: ApplicationFiled: June 4, 2007Publication date: March 25, 2010Applicant: MURAKAMI CORPORATIONInventor: Yasuhiro Sato

Publication number: 20100061113Abstract: A reflector 30 is constituted as an aspherical mirror that forms a light distribution S1 in which spread of reflected light in a longitudinal direction of the vehicle is larger than spread of reflected light in a lateral direction of the vehicle. The light distribution expanded in the longitudinal direction of a vehicle 3 makes the light less likely to impinge on a side surface of the vehicle 3, so that the rear part of the vehicle 3 can be illuminated efficiently. As a result, maximum illumination can be achieved with the minimum amount of light. In addition, because the range of illumination is long in the longitudinal direction, not only the area around an occupant's feet outside a front door 5 but also an area around the feet outside a rear door 6 can be illuminated easily.Type: ApplicationFiled: June 4, 2007Publication date: March 11, 2010Applicant: Murakami CorporationInventor: Yasuhiro Sato
