Embodiment 20

[0023] Figures 1-5C illustrate an embodiment 20 of a light display system of the present invention that generates and displays enhanced light emission.

[0024] As shown in FIG. 1 , the light display system 20 includes first and second electrodes 22 and 24 , a plurality of light emitting diodes 26 , a reflector 28 and an optical fiber 30 . The reflector 28 is assembled and forms a reflective cavity 32 and an annular ferrule 34 connecting the reflective cavity. A hole 36 is formed in the reflective cavity 32 for receiving the first and second electrodes 22 and 24 , and one end of the optical fiber 30 is inserted into the annular ferrule 34 .

[0025] Figure 1 further illustrates that the first and second electrodes 22 and 24 respectively form first and second element groups 36 and 38 of first and second finger elements 37 and 39 respectively, and the finger elements are arranged in an interdigitated comb Relationship 40. Each LED 26 is connected between a corresponding first ...

Abstract

Light-emitting diode display systems are provided which have enhanced light intensity. The enhanced intensity is realized with first and second electrodes, a plurality of light-emitting diodes and a reflector. The first and second electrodes respectively form first and second sets of first and second fingers respectively wherein the first and second fingers are arranged in an interdigitated relationship. Each of the light-emitting diodes is coupled between a respective one of the first fingers and a respective one of the second fingers and the reflector is arranged and positioned to reflect light from the light-emitting diodes. A plurality of diodes are thus positioned so that the reflector combines their light into a beam of enhanced intensity.

Description

technical field [0001] The invention relates to a light display system, in particular to a light emitting diode display system. Background technique [0002] Incandescent lamps and fluorescent lamps (commonly referred to as neon lamps) are widely used to form advertising signs, billboards, shop signs, window displays and the like. While fluorescent display tubes in particular can be offered in a variety of attractive colors and can be configured to form a variety of light display shapes (e.g., letters and numbers), they require high voltages (e.g., 12,000-20,000 volts), and They are extremely fragile, they require significant maintenance to minimize damage to them, and they are very expensive to build. [0003] In contrast, LED display systems can be used to display different colors and operate at very low voltages. They have been combined with optical fibers to simulate fluorescent display tubes, which are relatively robust and involve simple fabrication procedures. In c...
