<P>PROBLEM TO BE SOLVED: To provide a vehicle lighting fixture capable of improving distance visibility without reducing the efficiency of using light. <P>SOLUTION: In the vehicle lighting fixture 110, a laser light source device 1 includes a laser light source 10 emitting laser light from a laser emission port, a condenser lens 20 provided toward front of laser light source 10 in a laser emission direction converging the laser light, a phosphor part 40 generating mixed light by mixing the laser light with light having a different wavelength from that of the laser light and emitting it as light source output light, and a light guide part 30 forming a laser light optical path from the laser light source to the condenser lens. An end face 31 of the light guide part forms a reflection surface reflecting the light propagated in the light guide part 30 by total reflection. An optical system 112 generates a projection image so that an image portion formed in correspondence with the end face 31 of the light guide part 30 extends along the cutoff line in a light emitting area of the phosphor part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
