摘要： 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.

摘要： 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.
