  • Patent number: 8779022
    Abstract: Conventional curable polymers tend to shrink upon curing whilst low shrinkage ultraviolet light curing polymers have a problem with respect to curing below surface areas of a component. By providing light transmitting elements and/or local ultraviolet light source precursors, greater depth of ultraviolet curing can be achieved and therefore enhanced acceptability with regard to component manufacture. The light transmitting elements may be formed by optic fibers or coatings to existing reinforcing fibers or through consideration of the refractive index of the cured and uncured polymer to create light transmission paths through the component. Ultraviolet light source precursors can be activated by heat or a “seed” light exposure or vibration to create localised ultraviolet curing of the polymer thereabout.

  • Patent number: 7343704
    Abstract: Illuminated warning signs of familiar shapes employ back lighting through letters of smoked translucent plastic or glass. The back lighting is produced by incandescent lights or light emitting diodes located behind the letters. Thus, for example, in daylight a stop sign will appear to have black or white letters in contrast to the red background of the stop sign, but at night the letters will glow. Since warning signs provide shape to indicate the nature of the warning, the perimeter of the sign is likewise caused to glow brightly by providing one or a plurality of light pipes illuminated by lamps or a plurality of light emitting diodes. Thus, the combination of the word and the perimeter glowing brightly make clear the nature of the warning despite the sign being otherwise obscured.

A pair of transparent cover plates, which have a refractive index smaller than that of the light guide panel, cover respectively the first and second surfaces to return inward the light emanated outward from the first and second surfaces so that the light is efficiently propagated within the light guide panel. One of the cover plates has a pattern that forms a light exiting area.

  • Patent number: 6741042
    Abstract: A light emitting device for optic fiber decoration, includes a flash control IC, a plurality of different colored LED's, a variable resistor and a light-sensitive resistor, driven by 4.5V DC voltage to control the flash control IC, with output from the flash control IC controlling each LED to alternatively and gradually change flashing lights. Each LED projects lights into optic fibers, producing romantic light changes in the optic fiber decoration. The invention can be used to replace the light-emitting device, including light bulbs, a motor, color discs and such sophisticated structures in a conventional optic fiber decoration, and provides safer use, more energy saving and higher efficiency than conventional types.

  • Patent number: 6618529
    Abstract: A fiber optic display apparatus consists of a plurality of optical fibers which convey a projected image from an input, or first surface, to a display, or second surface, whose area is greater than or equal to that of the first surface, such that any image projected on to the first surface appears enlarged on the second surface. The second surface is comprised of tiles which attach to adjoining tiles by means of flexible tabs and pliable locator rods in such a fashion as to allow the second surface to follow general contours (e.g. concave or convex), while the optical fiber bundles from each tile are collected into a fixture to form the first planar surface. Because of the modular design of the display it can be assembled or disassembled rapidly.

  • Publication number: 20030142510
    Abstract: A self-illuminating device, having a light source part and a light guide part. A light source is enclosed in an enclosure, which further accommodates a power source, to provide a voltage to the light source and an integrated circuit. The integrated circuit adjusts and controls the power source supplied to the light source, so as to control brightness and color of the light source. The light guide part is preferably in a form of a plurality of light guide strips. Each of the light guide strips has one end received in the enclosure and coupled to the light source and the other end extending therefrom. Due to the light guide property, the light received at one end can be transmitted to the exposed other end of the light guide strips. Preferably, the exposed ends are arranged to display a desired pattern, design or logo.

  • Patent number: 6571043
    Abstract: This invention encompasses a method for the manufacture and rapid assembly of large screen fiber optic displays (1, 2) containing a very large number of individual fibers (thousands to hundreds of thousands, or more). The display surface is modularized into relatively small, thin, interchangeable, injection-molded square or rectangular tiles (3) to simplify manufacture and assembly. The hundreds of fibers (7) required for each tile (3) are machine-configured into a plurality of flat, flexible fiber optic ribbon cables (4), each cable (4) comprised of a planar geometric array of optical fibers (7) embedded in a thin adhesive matrix (8). The image emission end of each flat, flexible fiber optic cable (4) is a fiber manifold (20) joined to an injection-molded thermoplastic array of light guides (11), each fiber terminating in a single light guide or emitter (12).
