Abstract: A colorful illuminated sign construction utilizing plurality of fluorescent lamp covered by colored transparent plastic thin wall tubing which is tightly enclosed by a diffusion panel sleeve so that neighboring colors can be melted each other on the diffusing panel, and it forms a colorful stipes to attract attention. The fluorescent lamps and color sleeves are held by openings installed on side frame posts at the both end of fluorescent lamp whereby heat generated at the both end of fluorescent lamp can escape to surrounded air, and the side frame posts are connected to horizontal conduit and connecting bar which forms a structural frame of sign. Side frame post covers are protecting electrical wiring therein.

Abstract: An apparatus and method for producing a multisided, multicolored display which includes an enclosure with a plurality of translucent light scattering sides, top and bottom. A plurality of light sources are positioned in a spaced apart relationship to radiate sufficiently to illuminate all of the light scattering sides. Each of the light sources is of a different color, and the radiation from each source overlaps radiation from the other sources on the light scattering sides. A plurality of symbols may be interposed between the light sources and the light scattering sides to create colored images. Each of the enclosures represents a module, wherein several discrete modules are structured in a matrix fashion, and the entire matrix comprises the display.

Abstract: In a neon sign control device, a.c. power of an a.c. power source is connected to a neon transformer through an electronic switching element, a control signal from a control signal generator is supplied to a trigger circuit, the trigger circuit generates a trigger signal while the control signal is supplied, and the electronic switching element is rendered on by the trigger signal, whereby a.c. power is supplied to the neon transformer, and neon tubes connected to a secondary winding of the neon transformer are lit. A control unit composed of at least the electronic switching element and the trigger circuit is installed inside or outside of the transformer housing or disposed near the housing.

Abstract: Devices comprising a transparent chamber containing three mutually immiscible liquids two of which are colored yellow, cyan, or magenta with an external region colored yellow, cyan, or magenta. Static, they display four or more colored regions. When deformed or inverted, they create multicolor kinetic displays. Preferred devices comprise two liquid-filled, sheet-like chamberss in face to face relationship with five colored bands forming a rainbow pattern.

Abstract: Each of picture elements on a color display system is formed of a triad of small monochromatic cathode ray tubes luminescing in red, green and blue in response to unfocused electron beams from respective electron guns and disposed in a cylindrical housing. The tubes include identical components interconnected through respective leads extending externally of the housing. Alternatively, the housing may additionally include a driving source having a high voltage generator for applying an anode voltage to the tubes and leads extending externally of the housing which serve to energize the generator and tube heaters and to apply control signals to the tubes.

Abstract: A plurality of cellular concave mirror surfaces are formed on a plate-like reflector unit, and a plurality of light-emitting diodes are disposed on these cellular concave mirror surfaces to jointly form a colored light source. Connection wirings to be connected with a power supply source are provided on a substrate laminated with the reflector unit. A lamp base of a conventional type may be coupled to the substrate for being electrically connected to the wirings. This colored light source can provide a single or multiple color displays. Improved shadow pattern display can be provided by forming a complementary color pattern on a front cover lens. Letter, symbol or pattern display can be provided by selectively arranging light-emitting diodes on the reflector unit.

Abstract: A display apparatus is provided comprising a plurality of spaced lights with reflectors operatively associated with the lights which are isolated from one another. A circuit is provided for actuating the lights for selected periods of time to create an appearance of sequencing. Shaped lenses having the form of alphabetic characters or the like are associated with the lights and are illuminated thereby to achieve a desired effect. The reflectors and seperators associated therewith are connected together in a monolithic structure. The reflectors are asymmetrically formed in the case of asymmetrically shaped alphabetic characters in order to direct the light most appropriately through the shaped lenses. Sequencing is provided by the use of a binary counter, the output of which selectively actuates the lights.

Abstract: An amusement device providing a variety of lighting effects in which a housing is provided with a source of light positioned below two transparent turntables mounted for rotation, a mechanism for rotating the turntables, an independently operated mechanism for varying both the direction and speed of rotation of one of the turntables relative to the other, and a plurality of discs provided with a variety of cut-out patterns to be positioned on top of the turntables.

Abstract: Display apparatus including a display surface containing advertising and/or other informative or decorative matter and having at least portions thereof slotted or transparent. Diffraction grating means are positioned to the rearward side of the display surface and means are provided for illuminating the diffraction grating in order to create a color spectrum effect which is projected through the aforesaid transparent openings or slots, creating a highly aesthetically-pleasing effect, the distribution of the colors being changed with changes in position of the viewer. The openings may preferably be in the form of symbol or a composite thereof. The opaque regions of the display surface may, in one preferred embodiment, be reflective.

Abstract: A multiplicity of preferably coherent light sources are disposed along a common axis and are separated from one another by interposed opaque shields in the form of disks of progressively increasing diameters transverse to that axis. Each source confronts an associated screen with an annular light-receiving zone, which (except in the case of the last screen) may be integral with the respective shields, illuminated by light from all the preceding sources. The light sources may be individually modulated by external signals, e.g. oscillations derived from sound waves, to provide a visual pattern thereof.
