Abstract:
A luminous apparatus with functional symbols for illumination by transmitted light, the apparatus comprising:a transparent support element having a first surface; at least one first raised structure extending form the first surface in a first predefined area, the at least one first raised structure being shaped to represent at least one first functional symbol on the transparent support element; a first transparent color layer on said at least one first raised structure in said first predefined area, the first transparent color layer defining a first secondary surface substantially parallel with said first surface; and a non-transparent material defining a second surface and covering the first surface of the transparent support element in selected areas adjacent said at least one first raised structure without covering said first secondary surface in a manner leaving said first secondary surface exposed between portions of said non-transparent material on the support element thereby defining the spatial extent of the functional symbols, wherein the second surface is substantially flush with said first secondary surface.
