<P>PROBLEM TO BE SOLVED: To improve the design flexibility containing the thickness of a casing or the like and to respectively independently control an area in which light has to be enhanced and an area in which light has to be diffused as a background. <P>SOLUTION: With output light from an enhanced rendering part 216 as a first light source 228 and output light from a background rendering part 218 as a second light source part 230, light quantities can be controlled independently. Since the light-emitting surface 228A of the first light source 228 is disposed in vicinity of a light guide 236, most of the light emitted from the first light source 228 is guided to the enhanced rendering part 216 by the light guide 236, having no effect on the background rendering part 218. The light-emitting surface 230A of the second light source part 230 is situated sideways so as to uniformly distribute light to the whole area of a hollow part 238 corresponding to the background rendering part 218 of a lens cover 226 by the concave part 234 (slope 234A) of a refraction plate 224, so that the light has no ununiformity in light quantity and is completely separated from that from the first light source 228, having no effect on the enhanced rendering part 216. <P>COPYRIGHT: (C)2012,JPO&INPIT |
