Abstract: An LED lighted sign with a light diffuser sheet with embedded diffusion particles which provides a 20%-40% increase in lighting transmittance. There is also provided a light divider assembly having partitions which serve to segregate groups of LEDs for lighting only selected segments of the light divider assembly for displaying numerical images. Alternatively, there is provided an injection molded light diffuser lens of the same material which secures to each of several light diffuser chambers which combine to display numerical images. optionally, colored LEDs may be used to create color displays. Color filters may also be overlaid the light diffusers or color pigment may be added to the diffusion material during injection molding to create color displays. A molded light divider assembly is also provided in the alternative.

Abstract: Electronic indoor or outdoor alpha-numeric sign display system featuring readily accessible access to internally located electronic and other components from either the front or the rear of the sign display system for quick changeout of components. Opposing accessible spring latch rods located interiorly to a sign display module including a reflector/lens/louver assembly engage opposing catches on catch panels located in the interior of an enclosure or frame to secure the sign display module to the enclosure or frame. The spring latch rods are operated by special tools from the front or rear of the sign display system for disengagement of the sign display module from the enclosure or frame.

Abstract: A component mounting bracket system for mounting a component on a mounting wall having a pair of support apertures and a hole. The system comprises an upper bracket and a lower bracket mountable on a component. The upper bracket has a mounting aperture and the lower bracket includes a main portion and a pair of bracket arms attached to the main portion. The bracket arms are positioned in a spaced relationship and have a lower edge with a mounting notch opening downwardly for engaging a lower edge of one of the support apertures. The notches permit a relatively small degree of pivot movement of the lower bracket and the component mounted thereto with respect to the mounting wall while supporting the component in a position substantially adjacent to the mounting wall. The mounting aperture of the upper bracket forms a loop structure for looping over a fastener protruding from the hole in the mounting wall for hanging the component from the fastener.

Abstract: A lamp matrix display includes a vertical planar array of light sources arranged in rows and columns and a plurality of reflectors positioned about corresponding light sources and having reflector surfaces for directing the light emitted from the light source in a forward direction. The reflective surface of at least one of the reflectors includes multiple parabolic reflective surfaces having offset focal points. At least one lens is mounted in front of the reflectors. The lens may be a single lens having an inner flat surface disposed adjacent an outer edge of each reflector surface and an outer prismatic surface having vertical prisms to horizontally spread the light from the planar array of light sources. Further, the plurality of reflectors may be structurally supported about corresponding light sources by a matrix framework and the matrix framework may include a plurality of air vents.

Abstract: A light transmitting, visual display panel for use as a sign or message board and comprised of a plurality of closely adjacent, rectangular modules, each of which includes a closed, vertically disposed housing having top, bottom, side and back walls, and a front wall comprised of a plurality of closely adjacent, interchangeable, rectangular, 3-dimensional, light refracting filtering lenses. The lenses are removably secured in the housing. A vertical array of individual light sources is disposed within the housing behind the lenses and dividers behind the lenses separate the light sources. Each housing includes at least one pressurizing cooling fan and narrow, slot-like air exhaust ducts are provided between adjacent lenses.
