Abstract
A light assembly for mounting to a synoptic display panel is composed of a tile having a transparent surface portion, of a light-conducting transparent body, having at one end thereof adjacent to the tile, a diffusion surface, of a hollow block with baffles dividing the block into chambers in which are disposed light elements, and of a transparent plate mounted between the baffles housing and the transparent body; the transparent plate displays a geometrical pattern of colored areas, each area corresponding in shape to the cross-sectional area of a chamber with which it is in registry so that the light emitted from one of the light elements is colored by the area registered therewith, transmitted through the light-conducting body to the diffusion surface and emerges from the transparent surface portion of the tile.
