  • Patent number: 7222998
    Abstract: There is provided an LED as a light source and a reflector for reflecting a light emitted from the LED toward the surface of a license plate LP. The reflector has a first reflector disposed in a region getting out of the optical axis of the LED and a second reflector disposed in a region including the optical axis of the LED, and a light getting out of the optical axis and having a low luminous intensity is reflected by the first reflector to illuminate the vicinal region of the license plate and a light transmitted along the optical axis and having a high luminous intensity is reflected by the second reflector to illuminate a distant region from the license plate. An illuminance in the license plate can be made almost uniform so that the whole surface of the license plate can be illuminated in an equal brightness.
