Abstract
According to the present invention, additional reflection surfaces 9UL, 9UR, 9DL, 9DR are provided for reflecting light L6 from semiconductor-type light sources 5U, 5D on intermediate invalid reflection surfaces 9, 9L, 9R. As a result, the present invention is capable of: reflecting the light L6 from the semiconductor-type light sources 5U, 5D on the intermediate invalid reflection surfaces 9, 9L, 9R, by means of the additional reflection surfaces 9UL, 9UR, 9DL, 9DR; illuminating the intermediate invalid reflection surfaces 9, 9L, 9R; and lessening a dark part.
Claims6
A vehicle lighting device which is comprised of two light source/reflection surface units, said device comprising:
- a first light source/reflection surface unit which is comprised of a first semiconductor-type light source and a first reflection surface for reflecting and emitting light from the first semiconductor-type light source as a predetermined light distribution pattern;
- a second light source/reflection surface unit which is comprised of a second semiconductor-type light source and a second reflection surface for reflecting and emitting light from the second semiconductor-type light source as a predetermined light distribution pattern;
- a holder which is disposed between the first light source/reflection surface unit and the second light source/reflection source unit and by which the first light source/reflection surface unit and the second light source/reflection surface unit are held;
- an intermediate invalid reflection surface which is continuously provided between the first reflection surface and the second reflection surface and to which the light from the first semiconductor-type light source and the light from the second semiconductor-type light source are disallowed to be incident;
- and
- an additional reflection surface for reflecting to the intermediate invalid reflection surface, the light from the first semiconductor-type light source and the light from the second semiconductor-type light source.
