    • A segment type, electric light figure indicator including a casing defining a plurality of flat compartments wherein at least one of the compartments is sub-divided into a plurality of sub-compartments. Each sub-compartment has a cross-section in a lateral plane in the shape of a triangle, the bases of triangles being substantially linearly aligned. At least one light source is mounted in each sub-compartment in the apex angle of the triangle. A cover plate covers the top opening of the casing and has a plurality of slots which permit light emanating from the light sources to shine through, at least one of the slots being located parallel to, in front of and coextensive with the aligned bases of the triangles of the sub-compartments. The sub-compartments each have a reflecting wall inclined to the cover plate at an angle of about 15.degree. to 75.degree., the inclined wall being located immediately behind the slot coextensive with the aligned triangle bases. The slots are arranged so as to collectively form a desired figure.
    • 一种段式电灯图形指示器,包括限定多个平坦隔室的壳体,其中至少一个隔室被细分成多个子隔室。 每个子隔室具有三角形形状的横向平面中的横截面,三角形的基部基本上线性对准。 至少一个光源以三角形的顶角安装在每个子隔间中。 盖板覆盖壳体的顶部开口,并且具有多个狭槽,其允许从光源发出的光照射通过,至少一个狭槽位于平行于其前部并与之对齐的底座共同延伸 子舱的三角形。 副隔室各自具有以约15°至75°的角度倾斜到盖板的反射壁,倾斜壁位于与对准的三角形底座共同延伸的槽的正后方。 这些槽被布置成共同形成所需的图形。
