摘要： 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.

摘要： An illumination device for a vehicle includes: plural light sources that are disposed so as to be lined-up in at least one line, and that illuminate light; a light-blocking member having an opening portion onto which light illuminated from the light sources is incident; and a projecting lens that emits, toward an object, light that has passed through the opening portion of the light-blocking member and has been incident on the projecting lens.
