摘要: An illuminable sign (1) including a plate (2) of a light-transmitting material, at least one three-dimensional body, such as a convex strip (7), also of a light-transmitting material, in the form of a symbol, lettering, decoration or the like, and positioned on or over a surface of the plate (2), and a light source (4). The light source (4) is positioned along at least part of an edge (3) of the plate (2), such that, when the light source (4) is switched on, light from the source (4) is coupled into the plate (2). The illuminable sign (1) closely resembles a neon sign.
