Patent number: 10788184Abstract: A lighting device for a vehicle includes a light source that illuminates light, a reflecting surface, a shading member, and a projecting lens. The reflecting surface reflects the light illuminated from the light source and causes the light to converge. The shading member includes an aperture portion at which the light reflected and caused to converge by the reflecting surface is incident.

Patent number: 8568007Abstract: A vehicle headlight can include a semiconductor light source and a heat sink to radiate heat developed from the light source. The headlight can include a mounting base board mounting the light source and attached on a radiating base plate of the heat sink. At least one of a bottom surface of the mounting base board and the radiating base plate can include a concave portion in which a depth thereof is deeper than a maximum particle size of an inclusion of a thermal conductive viscous material that spreads in the concave portion. The light source can be located at a prescribed position in an accurate fashion without a positional misalignment while the heat developed from the light source can efficiently radiate via the heat sink. Thus, the disclosed subject matter can provide headlights including a radiation structure having a high radiating performance and positional accuracy for the light source.Type: GrantFiled: March 23, 2011Date of Patent: October 29, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Norikatsu Myojin, Masafumi Ohno
