<P>PROBLEM TO BE SOLVED: To attain a DRL light source unit which does not have luminance unevenness or luminance variation at high luminance by preventing influence of heating from a light source unit for a low beam and/or a light source unit for a traveling beam, in a vehicular lamp fitting having the light source unit for a low beam and/or the light source unit for a travelling beam, and the DRL light source unit using an LED as a light source, in a lamp chamber. <P>SOLUTION: A flat metal heat-shielding plate 43 is located at a lowermost section of the DRL light source unit 30, and the metal heat-shielding plate 43 is arranged with a gap 42 of a designated distance between itself and formed members along the formed members of the opposed DRL light source unit. Thus, heat generation from the light source unit 10 for a low beam and the light source unit 20 for a traveling beam arranged under the DRL light source unit 30 is radiated backward and upward along both sides of the metal heat-shielding plate 43. <P>COPYRIGHT: (C)2012,JPO&INPIT |
