  • Patent number: 7685753
    Abstract: An illuminated, shallow weatherproof signage character has individual three dimensional back-lighted/front/side and/or silhouette-lighting, with frosted areas of plastic, with virtually no limitation on the size or number of individual characters, which may be moulded or machined from solid plastic, which is U/V protected. Miniature, preferably LED lamps are concealed in the character. The life of the LED lamps is extended by limiting the applied voltage and the “on” time. The signage characters are usually elevated from their supporting surface, to effect back-lighting. Colored LED's or a RBG LED, can be used selectively to color the plastic signage.
