Filed: 2002-10-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a light guide plate and a lighting device that can illuminate the illumination light uniformly and efficiently only on the area that requires illumination.  <P>SOLUTION: The shape of the reflection area (reflecting face) 12c is formed in a shape, for example, a circular shape, that demarcates the bounds that requires illumination out of the illuminated object. The illumination light emitted from the emitting face 12b illuminates as an illumination area 21 only the same bounds as the shape of the reflection area 12c. By forming the reflection area 12c in a size smaller than that of the base face 12d, the illumination area 21 is limited compared with the case in which the reflecting face is formed on the whole face of the base face 12d, thereby, only the bounds which require illumination can be illuminated. Since the illumination light is not lighted on the surroundings of the bounds which require illumination, perceptivity of the illumination area 21 is increased.  <P>COPYRIGHT: (C)2004,JPO
