1. Field
The present invention relates generally to the electrical arts. More particularly, the invention relates to a light emitting assembly and a light-emitting floor system containing same.
2. Discussion of the Related Art
Viewers of musical concerts and other theatrical performances have come to expect more and more of the visual component accompanying the audio experience. Consequently, there is a need to enhance a concertgoer's sensations by mounting lighting assemblies to provide visual displays on floors, walls and ceilings.
It is a significant drawback of conventional light-emitting assemblies, in particular, light emitting assemblies used as stage floors, that the lighting elements must be protected from the performers at the expense of the visual experience. For example, in many conventional light-emitting assemblies, the lighting element must be recessed from surface, thus greatly diminishing the effectiveness of the lighting element. Consequently, it is a desideratum for lighting assemblies in which the lighting element is flush with the surface. Moreover, many conventional light-emitting assemblies must be covered with a protective surface, such as a transparent plastic surface. This is a drawback to stage designers and lighting technicians who prefer the black or other dark colored surface that is possible with a plywood or fiber board surface. More importantly, plastic surfaces are inherently slippery lacking the traction provided by plywood or fiberboard surfaces which can be of great importance to a performer. Consequently, it is also a desideratum for light-emitting assemblies that do not require a protective surface.
The aforementioned needs are satisfied by the light-emitting assembly in accordance with the invention. In some aspects, the light-emitting assembly is a flooring panel, a ceiling panel or a wall panel. And in some aspects, the light emitting assembly is part of a light-emitting floor system.
In one aspect, the light-emitting assembly includes a panel having a first side and an opposing second side with a plurality of bores extending from the first side to the second side and an LED light source comprising a circuit board, such as a printed circuit board and, in some aspects, a flexible printed circuit board, having a first side and an opposing second side, where the first side of the circuit board is adjacent to the second side of the panel. The LED light source further includes a plurality of LEDs and a plurality of optical wave guides, each wave guide having a first end and a second end, the first end disposed in one of the bores and the second end optically connected to one of the LEDs.
In some embodiments, the panel is a plywood panel, a fiber board panel, a plastic panel or a concrete panel. In some embodiments, the first side and the second side of the panel are parallel to one another and, in some embodiments, the first side and the second side of the panel incline toward one another. In some embodiments, the panel has a thickness of from about ½″ to about 1″ and, in some embodiments, a thickness of about ¾″.
In some embodiments, the bores have a diameter of from about 1 mm to about 12 mm and, in some embodiments, a diameter of from about 2 mm to about 6 mm. In some embodiments, the bores are arranged in a matrix with a distance of from about ¼″ to about ¾′ between the bores in each matrix column and from about ¼″ to about ¾′ between the bores in each matrix row.
In some embodiments, at least one LED provides a single color and, in some embodiments, at least one LED provides three colors.
In some embodiments, the first end of at least one optical wave guide is flush with the first side of the panel. In some embodiments, at least one optical wave guide comprises a cylinder having a length substantially the same as the length of a bore and press fit into a bore. And in some embodiments, the optical waveguides vary in length.
In some embodiments, at least one optical wave guide comprises an outwardly flaring portion extending beyond the second side of the panel and the end of the outwardly flaring portion contains a recess dimensioned to optically couple one of the LEDs. In some embodiments, the LEDs, the optical wave guides, and the bores are all aligned on an axis that is orthogonal to the first side and the second side of the panel.
In some embodiments, the light-emitting assembly further comprising a frame supporting the panel and the printed circuit board.
In another aspect, a light-emitting floor system includes a sub-floor panel and a plurality of adjoining light-emitting assemblies in accordance with the invention. In some embodiments, each panel is square or rectangular and the lengths of the sides of adjoining panels are the same. In some embodiments, the adjoining light emitting assemblies are removably secured to the surface of the sub-flooring panel.
Particular embodiments of the invention are described below in detail for the purpose of illustrating its principles and operation. However, various modifications may be made and the scope of the invention is not limited to the exemplary embodiments described below.
In some aspects, the light-emitting assemblies can be used as floor panels covering an underlying floor or sub-floor, as ceiling panels or as wall panels, including as panels covering an underlying wall, as free standing panels to create partition walls or simply as decorative panels hung on an existing wall. The light emitting assemblies can be used singly or can be interconnected. In some aspects, the light emitting assembly is a light-emitting floor panel, suitable for assembly with similar light emitting assemblies having sides with the same dimensions into a light-emitting portable floor that may be subsequently dismantled for reassembly on subsequent occasions at the same or another location.
In some aspects, the light emitting assembly is generally square or rectangular and, in some embodiments, each light-emitting assembly has a square shape with sides of two feet in length. The light-emitting assemblies, however, can be of any desired shape and size. The light-emitting assemblies can be secured to an underlying surface by any suitable means and in some aspects are releasably secured to the underlying surface.

A plurality of bores 110 for emitting light through the panel 104 extend from the panel's first side 106 to its second side 108. Each bore has a first end 112 and a second end 114.
In some aspects, the bores 110 have a diameter of from about 1 mm to about 12 mm and in some aspects, the bores have a diameter of from about 2 mm to about 6 mm. As illustrated in
Any suitable LED light source can be used, including circuit boards and individual LED pixels connected with wires. In the representative embodiment shown in
A plurality of LEDs 122 is provided on the first side 118 of the printed circuit board 117. The LEDs can be, for example, conventional LEDs, organic LEDs (OLEDs) or polymer LEDs (PLEDs). One end of each of the electrical contacts is also coupled with an LED 122. The LEDs may be soldered in a conventional manner or may be the more compact surface mounted type. Thus, each LED is electrically coupled with a controller. Each LED is also coupled with a power source.
The LEDs 122 may provide a single color, for example red, to provide a monochrome display. Alternatively, an LED matrix may be made up of three different colors, for example, red, green and blue, of LED. Alternatively, tricolor LEDs, which are single LEDs able to display three different colors, for example, red, green and blue, may be used. With either of these latter two arrangements it is possible to provide a full color display.
