To provide an illumination structure which can obtain such an illumination structure as to suitably achieve both illumination of a whole design of a character plate using a prism, and illumination of a specific design by a corresponding light source, while suppressing an uneven phenomenon.SOLUTION: An illumination structure includes a character plate 11, a light source 14b arranged on a rear side Z2 of the character plate 11, and a prism 12 arranged between the character plate 11 and the light source 14b. The illumination structure includes a plurality of design parts 11a which are provided on the character plate 11 and permeate light in a thickness direction Z, a first light source 141 for irradiating the whole design part 11a with light, a second light source 142 for irradiating a specific design part 111 in the design part 11a with light, and a second regulation part 132 for surrounding the second light source 142 and regulating an irradiation range of the second light source 142 by an opening 132a. An opening side width dimension W1 in a lateral direction Y in the opening 132a of the second regulation part 132 is smaller than a design side width dimension W2 in the lateral direction Y of the specific design part 111.SELECTED DRAWING: Figure 3

    【課題】ムラ現象を抑制しつつ、プリズムを用いた文字板の意匠全体の照明と、対応する光源による特定の意匠の照明と、を好適に両立可能な照明構造を得ることを目的とする。【解決手段】照明構造は、文字板11と、文字板11の裏側Z2に配置される光源14bと、文字板11と光源14bとの間に配置されるプリズム12と、を備えている。照明構造は、文字板11に複数設けられ、厚さ方向Zに光を透過する意匠部11aと、意匠部11a全体に光を照射する第一光源141と、意匠部11aのうち特定意匠部111に光を照射する第二光源142と、第二光源142を囲み開口132aによって第二光源142の照射範囲を規定する第二規定部132と、を備えている。第二規定部132の開口132aにおける横方向Yの開口側幅寸法W1は、特定意匠部111の横方向Yの意匠側幅寸法W2よりも小さい。【選択図】図3
