In an illumination device for license plate which illuminates the license plate from the front side thereof, at least one light source consist of a white LED is arranged at a position upward or obliquely upward of the license plate in such a manner that optical axes thereof traverse with a lower range than the center of the license plate, and a reflector is arranged at a position obliquely downward seen from an observer's side of the light source, receiving a light directing to the observer's side from a portion of a light emitted from the light source, and converting the light into a light irradiating the center or the lower part of the license plate. Further, a garnish for accommodating the light source and having a light transmitting part can be provided to the illumination device.

What is claimed is: 1. An illumination device for a license plate, comprising: at least one light source arranged in a circumference of the license plate; a garnish for accommodating the at least one light source and having a light transmitting part; and a reflector converting a light emitted from the at least one light source into a first light irradiating the license plate and a second light irradiating the garnish, wherein the light source consists of a white LED. 2. The illumination device according to claim 1, wherein a plurality of the at least one light sources are arranged with spaces along the upper end of the license plate. 3. The illumination device according to claim 1, wherein a light transmissive cover having a light diffusion treatment is arranged so as to cover the at least one light source and the reflective member. 4. The illumination device according to claim 1, wherein said reflector comprises: a spectral member for directing said first light to irradiate the license plate and said second light to irradiate the garnish from the light emitted from the at least one light source. 5. The illumination device according to claim 4, wherein the spectral member comprises: a light guide member having a light transmitting property; and the light guide member including: a light incident face upon which light emitted from the at least one light source is incident; a first light emitting face for emitting the first light from a portion of the light incident from the light incident face; and a second light emitting face for emitting th second light from a portion of the light incident from the light incident face. 6. The illumination device according to claim 4, wherein the spectral member includes: a first reflecting face to direct said first light from a portion of the received light; and a second reflecting face to direct said second light from a portion of the received light. 7. The illumination device according to claim 1, wherein the at least one light source includes: a sealing member for directing said first light to irradiate the license plate and said second light to irradiate the garnish. 8. The illumination device according to claim 7, wherein a direction of the first light is substantially perpendicular to an optical axis of the light emitted from the light emitting element, and a direction of the second light is substantially parallel to the optical axis of the light emitted from the light emitting element. 9. The illumination device according to claim 1, wherein said reflector comprises: a spectral member for generating said first light to irradiate the light transmitting part from a portion of the light emitted from the light source, wherein the light source directly irradiates the first light on the license plate. 10. The illumination device according to claim 1, further comprising: a spectral member for direction said first light to irradiate the license plate from a portion of the light emitted from the at least one light source, wherein said light transmitting part directly receives the light emitted from said at least one light source. 11. An illumination device for a license plate, comprising: at least one light source arranged in a circumference of the license plate; a garnish for accommodating the at least one light source and having a light transmitting part; and means for converting a light emitted from the at least one light source into a first light irradiating the license plate and a second light irradiating the garnish, wherein the light source consists of a white LED. 12. The illumination device according to claim 11, wherein said means for converting comprises: a spectral member for directing said first light to irradiate the license plate and said second light to irradiate the garnish from the light emitted from the at least one light source. 13. The illumination device according to claim 12, wherein the spectral member comprises: a light guide member having a light transmitting property, wherein the light guide member includes: a light incident face upon which light emitted from the at least one light source is incident; a first light emitting face for emitting the first light from a portion of the light incident from the light incident face; and a second light emitting face for emitting the second light from a portion of the light incident from the light incident face. 14. The illumination device according to claim 11, wherein the spectral member includes: a first reflecting face to direct said first light from a portion of the received light; and a second reflecting face to direct said second light from a portion of the received light. 15. The illumination device according to claim 11, wherein the at least one light source includes: sealing means for sealing said at least one light source and for directing said first light to irradiate the license plate and said second light to irradiate the garnish. 16. The illumination device according to claim 15, wherein said means for converting comprises: means for reflecting and guiding said first light to irradiate the license plate and said second light to irradiate the garnish. 17. The illumination device according to claim 15, wherein a direction of the first light is substantially perpendicular to optical axis of the light emitted from the light emitting element, and a direction of the second light is substantially parallel to the optical axis of the light emitted from the light emitting element. 18. The illumination device according to claim 11, wherein said means for converting comprises: a spectral member for directing said first light to irradiate the light transmitting part from a portion of the light emitted from the at least one light source, wherein the light source directly irradiates the first light on the license plate. 19. The illumination device according to claim 11, wherein said means for converting comprises: a spectral member for directing said first light to irradiate the license plate from a portion of the light emitted from the at least one light source, wherein said light transmitting part directly receives the light emitted from said at least one light source.
