Publication number: 20140204599Abstract: A vehicle component includes a molded cover molded into a shape of a surface of a part attached to a vehicle and a surface-emitting device bonded or fitted and fixed along a back face of the molded cover. The molded cover is vacuum formed by solid decorative molding of a translucent resin molded member with a translucent film, and light from the surface-emitting device is transmitted through the molded cover and emerges in a predetermined light-emitting area which is a part of a surface of the vehicle component. The vehicle component obtains a light-emitting function with a relatively simple structure and in a relatively compact form with a design not impaired and excellent in beauty and appearance.Type: ApplicationFiled: August 8, 2012Publication date: July 24, 2014Applicants: Fu-se Vacuum Forming CO., LTD., KOHKI CO., LTD.Inventors: Takayuki Miura, Yoshihiro Kamiike, Yuichi Ohga

LIGHT MODULE FOR A MOTOR VEHICLE HEADLAMP, CONFIGURED TO GENERATE A STRIPE-SHAPED LIGHT DISTRIBUTION
Publication number: 20140198513Abstract: A light module for a motor vehicle headlamp having an optical fiber configuration with at least one first optical fiber branch and one second optical fiber branch. Each of the two branches has a light exit surface each bordered by two narrow sides and disposed such that a narrow side of the first branch is disposed parallel and directly adjacent to a narrow side of the light exit surface of the second branch. Each branch exhibits two transport surfaces. The transport surfaces exhibit surface norms having a directional component, which faces more toward a first narrow side of the two narrow sides of the branch than toward a second narrow side of the two narrow sides of the branch, wherein the narrow sides lying directly adjacent and parallel to one another are a second narrow side of the first branch and a first narrow side of the second branch.Type: ApplicationFiled: January 8, 2014Publication date: July 17, 2014Inventors: Emil P.

Publication number: 20140177249Abstract: While a light source is arranged on the back side of a light guide lens, light beams can be emitted from the light source with respective optical axes directed in one direction and be guided toward opposite ends of the light guide lens. A light source and a reflective surface are arranged on the back side of a light guide lens. The light source emits light beams with respective optical axes directed in one direction. One of the light beams obliquely enters the light guide lens toward one end in a long direction of the light guide lens without being reflected by the reflective surface. Another one of the light beams is reflected by the reflective surface and obliquely enters the light guide lens toward another end in the long direction of the light guide lens.Type: ApplicationFiled: December 20, 2013Publication date: June 26, 2014Applicant: MURAKAMI CORPORATIONInventors: Kota ISEKI, Hiroaki NAGANO, Akihito INABA
