に前記光源からの光線の進行方向に向かって前方へ傾斜
する厚さ寸法が均一もしくはほぼ均一な平板形状の導光
部とを少なくとも有し、且つ前記導光体の後面の前記光
透過性表示部材の表示部分と対応する箇所には前記受光
部から入った光透過性表示部材の方向へ反射する反射部
を設け、この反射部は前記受光部に向かって横列並行状
となるようその稜線が光線進行方向に対して直交もしく
はほぼ直交状態で前記光源位置をほぼ中心とする同心同
上に形成して成るｖ字溝であり、また前記光透過性表示
部材と前記導光体との間には光線の一部は透過するが一
部は反射する性質の半透過性反射板を設け、この半透過
性反射板の後面には光線の一部を反射する材料から成る
反射層を設けたことを特徴とする照明装置。In an illumination device that illuminates the light transmitting display member from behind by introducing irradiation light from a light source into a light guide disposed behind the light transmitting display member, the light guide transmits the light rays into the interior. at least a light-receiving part into which the light-receiving part is inserted, and a flat-plate-shaped light guide part having a uniform or almost uniform thickness that extends integrally from the light-receiving part and slopes forward in the traveling direction of the light ray from the light source, Further, a reflecting part is provided on the rear surface of the light guide at a location corresponding to the display part of the light-transmitting display member, and the reflecting part reflects the light entering from the light-receiving part in the direction of the light-transmitting display member. V-shaped grooves are formed concentrically with the light source position as the center, with the ridge lines being perpendicular or almost perpendicular to the light beam traveling direction so that the grooves are horizontally parallel to the light beam, and A semi-transparent reflector is provided between the gender display member and the light guide, which allows part of the light to pass through and reflects the other part of the light. A lighting device characterized by being provided with a reflective layer made of a material that reflects.
