Abstract

PURPOSE: To excellently recognize a character, a figure, etc., formed by light emission bodies. CONSTITUTION: Light emission diodes 14 are in guide holes 16 and covered with a lens plate 24 having plural convex lens parts 22. The respective convex lens parts 22 are connected together in series. Light from a light emission diode 14 enters the convex lens part 22 in a random direction by being reflected in the guide hole 16. The light is emitted out as if the whole convex lens part 22 illuminated. The convex lenses 22 are mutually connected successively, so lights from the respective convex lens parts 22 are not one point and the adjacent convex lens parts 22 are recognized as a continuous line or plane.

When the light emitting diode 14 is turned on in the light emitting display device 10 having such a structure, the light passes through the guide hole 16 and reaches the corresponding convex lens portion 22 as shown in FIG. The light is emitted from the convex lens portion 22 to the outside. The light from the light emitting diode 14 enters the convex lens portion 22 in a random direction due to reflection in the guide hole 16 or the like. Further, the convex lens portion 22 receives internal reflection and refraction, and is irradiated to the outside from the convex lens portion 22 as if the entire convex lens portion 22 emits light. Since the plurality of convex lens portions 22 are adjacent to each other and are connected to each other, the light from each convex lens portion 22 is not recognized as a single point, but the adjacent convex lens portions 22 are recognized as a continuous line or surface. Therefore, the convex lens portions 22 (= light emitting diodes 14) are not observed in a separated state not only from a long distance but also from a short distance. Therefore, when the light emitting diode 14 corresponding to a desired character or figure is turned on, the character or figure can be satisfactorily recognized by the light emitted from the convex lens portion 22.
