An illuminated device comprising a rod 10 of an optically transparent material with light source 11 located at least at one end of the rod thus to transmit light into the rod for total reflection therewithin, and a linear reflector 12 extending longitudinally of the rod at a position thereon to reflect light transmitted through the rod and to create a beam of such reflected light emitted from the outer surface of the rod in a transverse direction. Such devices may be used for signage and produce a linear beam of considerable brilliance and colour from a low-power light source such as one or more LED's. |
