Road sign projector and vehicle lamp

1. A road sign projector displaying images onto a plurality of regions of a road surface, comprising:

a shade configured to shape image projection light into a predetermined shape corresponding to the image for each of the regions;

a plurality of projection lenses;

a solid-state light source correspondingly arranged to each of the plurality of projection lenses and configured to emit the image projection light; and

a plurality of light-guiding members each correspondingly arranged to each of the solid-state light sources and configured to guide the image projection light toward the shade,

wherein each of the projection lenses is illuminated by the plurality of solid-state light sources, and

wherein each the plurality of the light-guiding members are connected to one another at a side opposite the solid-state light source.

2. The road sign projector according to claim 1 ,

wherein the plurality of projection lenses are different from one another in at least one of a focal length and axial inclination.

3. The road sign projector according to claim 2 ,

wherein at least one of the projection lenses has a shape that is Off-Axis as well as being cut off at a portion out of an effective area.

4. The road sign projector according to claim 1 ,

wherein at least one of the plurality of projection lenses has a function of projecting at least two regions of the plurality of regions.

5. The road sign projector according to claim 1 ,

wherein the plurality of light-guiding members are made of a heat-resistance material.

6. The road sign projector according to claim 1 ,

wherein an emitting end of each the plurality of light-guiding members have a convex surface.

7. The road sign projector according to claim 6 ,

wherein an emitting end of each the plurality of light-guiding members have a convex surface which is made of an aspherical surface or a free-form surface.

8. The road sign projector according to claim 7 ,

wherein a convex curvature at a boundary portion of the emitting end of each the plurality of light-guiding members are smaller than a convex curvature at a center portion thereof.

9. The road sign projector according to claim 6 ,

wherein inclination of an incident end of at least one of the plurality of light-guiding members is different from inclination of an emitting surface of the corresponding solid-state light source.

10. The road sign projector according to claim 1 ,

wherein a gap between each of the plurality of solid-state light sources and the corresponding each of the plurality of light-guiding members is filled with a heat-resistance transparent member.

11. The road sign projector according to claim 1 ,

wherein a region of the shade from a center portion to a circumferential portion curves toward the corresponding projection lens.

12. The road sign projector according to claim 1 further comprising

a light-guiding-member fixing tool correspondingly arranged to each of the solid-state light sources and configured to position each of the plurality of light-guiding members.

13. A vehicle lamp comprising:

a road sign projector displaying images onto a plurality of regions of a road surface; and

a directional indicator,

wherein a light source of the road sign projector and a light source of the directional indicator are a common solid-state light source,

the road sign projector has:

a shade configured to shape image projection light into a predetermined shape corresponding to the image for each of the regions;

a projection lens corresponding to each of the regions, and

a plurality of the light-guiding members are connected to one another at a side opposite the solid-state light source

the directional indicator has a directional-indicator display unit corresponding to each of the regions, and

each of the directional-indicator display units displays a directional indicator when the image is displayed in the corresponding region.
