Segment type, electric light alpha-numeric figure indicator

Abstract

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.
