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.

Abstract: A process for attaching posters or related items onto an illuminated carrier film of translucent material, which runs from one reel to another and back again, provides for elimination of a light beam between adjacent posters. In this process an individual poster is flexibly secured to the carrier film at the edges of the poster, and the edges of two adjacent posters are positioned in pockets. The pockets are formed by two tongues of a translucent guide fixed to the carrier film of translucent material and extending perpendicular to the reel direction. One poster (10L) is fed into a first pocket (19) bordered by the carrier film (2) and a first tongue (15), and the other poster (10R) is fed into a second pocket (18) which is bordered by the first tongue (15) and a second tongue (17) connected to the first tongue and positioned away from the first pocket (19). This is done in such a way that the edge areas of the posters (10L, 10R) overlap one another in the pockets.

Abstract: A light unit for use in lighted sign assemblies has a housing with a rear wall, upstanding opposed side walls, and shield elements extending inwardly from adjacent the upper ends of the side walls. Light arrays extending along the side walls have light emitting diodes disposed in spaced relationship above the rear wall and below the shield elements, and a diffuser extends across the housing above the shield elements. The rear wall is configured to reflect light emitted from the diodes relatively uniformly across the diffuser which further contributes to relative uniform transmission of light therethrough. The power supply may include a circuit to transform alternating current line voltage into a reduced direct current voltage for the diodes, and the power supply may also provide direct current to the diodes from a battery power source when power is interrupted.

Abstract: A star projection device is formed from an opaque film sheet folded to form a six-sided, cubical enclosure, the film having transparent spots extending over its entire area representing star positions when projected onto a surrounding surface, and a small, point-like light source is positioned at the center of the enclosure for projecting light simultaneously through all of its six sides to produce a substantially 360.degree., horizonless projection of the stars onto surrounding surfaces. Nearby stars are represented by linear extensions from the transparent spots representing vectors corresponding to the magnified heliocentric parallax motion of the star.
