BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates, generally, light fixtures and methods for mounting light sources, particularly, to light fixtures having rings having light sources where the rings are suspended from cords adapted to transmit power to the light sources, for example, LEDs.
2. Description of Related Art
A light fixture must be electrically powered. Typically, power is provided to a light fixture by one or more electrical power cords. Historically, light fixture designers must incorporate the routing of electrical power to the lights in their fixtures. In the design of conventional fixtures, for example, chandeliers and lamps, some form of body, frame, or other structure is provided through which or along which electrical power cords and wires can be routed without incident. However, when light fixtures are designed with more delicate or ethereal appearances, structures within which power cords can be routed may not be available. Lacking such structures thought which the power cords can be routed, it is a challenge for the lighting designer to provide appropriate power to the fixture. Aspects of the present invention address this disadvantage of conventional lighting design.
SUMMARY OF ASPECTS OF THE INVENTION
Faced with the limitations of conventional methods of providing electrical power to lighting fixtures and the competing desire to provide an open, light, somewhat ethereal light fixture design, the inventors of the present invention overcame this challenge by incorporating the electrical power routing into the structures supporting the light fixture. According to aspects of the present invention, electrical power is provided to the light sources in a light fixture through the support cords or wires that suspend the light fixture.

As shown in FIG. 1, light fixture 10 may typically include a mounting escutcheon or canopy assembly 22 by which fixture 10 may be mounted to a surface 24 (shown in phantom), for example, to a ceiling or overhang. Electric power may typically be provided to canopy assembly 22 via electrical wire or cable 26, for example, conventional 120 or 240 volt AC power from the local electrical grid, though one or more batteries may be located in canopy 22. As discussed above and below, according to aspects of the present invention, electrical power may be directed from wire 26 to canopy assembly 22 and then to cords 14 and/or cords 18 to power light sources 20 in rings 12 and 16. Details of this electrical power distribution will be descried with respect to FIGS. 10, 11, and 12 below.
As shown in FIG. 2, rings 12 and 16 may typically vary in outside dimension. In one aspect, ring 12 may have an outside dimension 28, for example, a maximum lateral dimension, such as, a width or diameter, and ring 16 may have an outside dimension 30, for example, a maximum lateral dimension, such as, a width or diameter. In one aspect, maximum lateral dimension 28 may be substantially equal to maximum outside dimension 30, however, typically, ring 12 may have smaller maximum outside dimension 28 than maximum outside dimension 30 of ring 16. In another aspect, ring 12 may have larger maximum outside dimension 28 than maximum outside dimension 30 of ring 16. According to aspects of the invention, lateral dimensions 28 and 30, for example, diameters, may typically range from about 50 millimeters [mm] to about 10 meters [m], but are typically between about 200 mm and 1 m in outside dimension. For example, width or diameter 28 may range from about 2 m to about 5 m and the width or diameter 30 may range from about 2 m to about 5 m.
As also shown in FIG. 2, rings 12 and 16 may be separated by a vertical dimension 32, for example, a height or an elevation. According to aspects of the invention, vertical dimension 32 may typically range from about 50 mm to about 5 m, but is typically between about 100 mm and 500 mm. For example, vertical dimension 32 may range from about 200 mm to about 400 mm.
As shown most clearly in the top plan view of FIG. 3, in one aspect of the invention, first ring 12 and second ring 16 may be circular in shape. However, rings 12 and 16 may comprise a broad range of geometric shapes according to aspects of the invention. For example, rings 12 and 16 may also be elliptical rings or polygonal rings, for example, triangular rings, square rings, rectangular rings, pentagonal rings, hexagonal rings, or octagonal rings, among other polygonal ring shapes. FIGS. 4 through 7 are top plan views, similar of FIG. 3, of light fixtures according to further embodiments of the invention having various shapes for rings 12 and 16. For example, as shown in FIG. 4, light fixture 34 may have rings 35 and 36 that are rectangular in shape; as shown in FIG. 5, light fixture 37 may have rings 38 and 39 that are elliptical in shape; and, as shown in FIG. 6, light fixture 40 may have rings 41 and 42 that are hexagonal in shape. As shown in FIG. 7, rings 12, 16 may also vary in geometric shape, for example, light fixture 43 shown in FIG. 7 may have a ring 44 that is rectangular in shape and a ring 45 that is hexagonal in shape. Other combinations of shapes for two (or, as discussed below, three) or more rings 12, 16, may be provided according to aspects of the invention, and the myriad of possible combinations of ring shapes will be readily apparent to those of skill in the art without further elaboration.
FIG. 8 is cross-sectional view of the rings 12 and 16 shown in FIG. 3 as viewed along the two sets of section lines 8-8 shown in FIG. 3. FIG. 9 is a partial perspective view of rings 12 and/or 16 according to one aspect of the invention. As shown in FIGS. 8 and 9, rings 12 and/or 16 may comprise hollow rings having an inner wall 46 and an outer wall 48. Timer wall 46 and outer wall 48 may be joined or coupled by any conventional means, for example, mechanical fasteners or welding. In the aspect, shown in FIG. 8, inner wall 46 and outer wall 48 may be joined by plurality of mounting plates 54 mounted on inner wall 46 and a plurality of mounting plate 56 mounted on outer wall 48, by a plurality of mechanical fasteners 52. Mounting plates 54 and 56 may be mounted on inner wall 46 and outer wall 48, respectively, by welding or brazing. In some aspects of the invention, rings 12 and 16 may include a top wall or plate 47 and/or a bottom wall or plate 49 (both shown in phantom in FIG. 8). Top wall 47 and/or bottom wall 49 may completely encircle or cover rings 12 and 16, or may intermittently cover rings 12 and 16, for example, providing a plurality of openings or gaps between individual sections of top wall 47 and/or bottom wall 49. Inner wall 46, top wall 47, outer wall 48, and bottom wall 48 may be opaque, translucent, or transparent. In the aspect of the invention shown in FIGS. 8 and 9, inner wall 46 and outer wall 48 of rings 12 and 16 are opaque, for example, typically comprising thin gauge sheet metal, though plastics may be used.
FIGS. 8 and 9 also illustrate a plurality of light sources 58 that may be mounted in rings 12 and 16 according to aspects of the invention. Though, according to the invention, different types of light sources 58 may be used, for example, incandescent bulbs, fluorescent bulbs, and the like, in the aspect of the invention shown in FIGS. 8 and 9, light sources 58 comprise light-emitting diodes (LEDs) mounted to the inner surface 60 of outer wall 48 of rings 12 and 16. According to some aspect of the invention, light sources 58 may be mounted to the inner surface 62 of inner wall 46 of rings 12 and 16. In one aspect, for example, for larger embodiments of the invention, light sources 58 may be mounted to both surfaces 60 and 62. In addition, light sources 58 may direct light in any desired direction, but light sources 58 typically may direct light in an axial direction, that is, in a direction generally parallel to the axis of the light fixture. For example, in one aspect, light may be directed by light sources 58 in a vertical direction, such as, an upward vertical direction, as indicated by arrow 64 in FIG. 8, a downward vertical direction, as indicated by arrow 66, or both. Light sources 58 may be mounted to surfaces 60 or 62 of ring 12 or 16 by conventional means, for example, by mechanical fasteners or by an adhesive. In the aspect shown in FIGS. 8 and 9, light sources 58, that is, LEDs, are mounted to a strip 68 having an adhesive adapted to mount strip 68 with light sources 58 to surface 60, 62, or both. In one aspect of the invention, the strip-mounted LEDs used for light sources 58 may be model number L32LFE/10V765/SD/14FT strip-mounted LEDs provided by Osram Sylvania.
As shown in FIG. 9, light sources 58 may typically be electrically powered by electrical leads or wires 70 and 72, for example, with direct current (DC), for instance, 10 to 50 volts DC (VDC) or alternating current (AC), for instance, 120 volts AV (VAC) or 240 VAC. As discussed below, according to one aspect of the invention electrical power may be provided to light sources 56 through cords 14 and/or cords 18, that is, via the cords supporting rings 12 and 16.
FIGS. 1 through 10 also illustrate a method for suspending a plurality of light sources according to one aspect of the invention. The method includes or comprise: suspending a first ring 12 by a plurality of first cords 14; and suspending a second ring 16 by a plurality of second cords 18 from the first ring 12, wherein at least one of the first ring 12 and the second ring 16 comprises a plurality of light sources 58 and wherein at least one of the plurality of first cords 14 and at least one of the plurality of the second cords 18 are adapted to transmit electrical power; and powering the plurality of light sources 58 through the at least one of the plurality of first cords 14 adapted to transmit electrical power and the at least one of the plurality of second cords 18 adapted to transmit electrical power. In one aspect, the method further comprises directing light from the light sources 58 in an axial direction, for example, an upward vertical direction and/or a downward vertical direction.
FIG. 10 is an exploded perspective view of the canopy assembly 22 shown in FIG. 1 according to one aspect of the invention. As shown, canopy assembly 22 includes a mounting plate, or “washer,” 23 adapted to secure light fixture 10 to surface 24 (see FIG. 1), one or more power supplies, wiring, and electronics 25 mounted to mounting plate 23, supporting cords 14 mounted to mounting plate 23, and a canopy cover 27 mounted over power supply, wiring and associated electronics 25 and to mounting plate 23. FIG. 11 is a side elevation view of the exploded perspective view of the canopy assembly 22 shown in FIG. 10 and FIG. 12 is a bottom perspective view of the canopy assembly 22 shown in FIG. 10 with the canopy cover 27 removed to facilitate illustration of aspects of the invention.
As shown in FIGS. 10, 11, and 12 the mounting plate 23 of canopy assembly 22 may be a thin, typically, metallic, plate adapted to be mounted to surface 24, for example, bolted to an electrical junction box (not shown) located behind surface 24 (see FIG. 1). As shown most clearly in FIG. 12, one or more power supplies, wiring, and electronic 25 may typically be mounted to one surface of mounting plate 23 and the plurality of cords 14 that suspend rings 12 and 16 may be mounted to or suspended from mounting plate 23.
As is typical, electrical power may be provided to canopy assembly 22 of light fixture 10 by a wire 74, for example, a Romex-type sheathed electrical cable, as is conventional, though in some aspects of the invention electrical power may be provided by one or more batteries positioned in canopy assembly 22. According to an aspect of the invention, the electrical power provided, for example, by wire 74, is conditioned or otherwise modified to provide electrical power to one or more support cords 14 whereby the one or more support cords 14 provide electrical power to the light sources 58 in ring 12 and/or ring 16. That is, according to one aspect, cords 14 may function as not only support to ring 12 and/or ring 16, but may also conduits for transmitting electrical power to the light sources 58 of ring 12 and/or ring 16.
According to aspects of the invention, any combination of electronics and wiring 25 that effectively provide an appropriate level of electrical power from, for example, wire 74 to cords 14 and/or cords 18 to power light sources 58 may be used, and will be apparent to those of skill in the art. However, one effective arrangement of power supplies, wiring, and associated electronics 25 that may be used is illustrated most clearly in FIG. 12.
Electrical power, for example, 120 VAC at between about 5 and 120 amperes (A), depending upon the size and number of light sources 58, may be provided by wire 74 to canopy assembly 22. As shown in FIG. 12, electrical power supplied by wire 74 may be introduced to a connection box 76. Connection box 76 may simply provide an interface between the supply voltage, for example, 120-240 VAC, and the electrical components 25. As shown in FIG. 12, the wires 79 and 81 from connection box 76 may provide electrical power, for example, 120-240 VAC, to at least one, but typically, two, power supplies 78 and 80 via wires 79 and 81, respectively. Power supplies 78 and 80 may be typical power supplies adapted to convert supply voltage, for example, 120-240 VAC, to an appropriate voltage for powering light sources 58, for example, about 10 to about 50 VDC. It will be apparent to those of skill in the art that, if the supply voltage provided by wire 74 is compatible with the voltage required for light sources 58, for example, about 10 VDC, power supplies 78 and 80 may be omitted. The output of power supplies 78 and 80, for example, about 10 to about 50 VDC, is provided to connection box 82 via wires 84 and 86. Connection box 82 provides a common junction for providing power, in one case, 10 VDC to cords 14. In one aspect, only a single power supply, 78, 80 may be used to power aspects of the invention; however, two or more redundant power supplies 78, 80 may be provided to help ensure the desired power is provided and to extend the working life of the power supplies.
The output of connection box 82 is electrically connected to cords 14 via wires 88 and 90. As shown in FIG. 12, in one aspect, wires 88 and 90 may be electrically connected to cord mounts 92 and 94, for example, by means of connectors mechanically fastened to cord mounts 92 and 94. At least one other cord mount 96 may be provided to mount a third cord 14 to plate 23. Cord mounts 92, 94, and 96 may be mounted to plate 23 by mechanical fasteners 99, for example, screws, as shown most clearly in FIGS. 10 and 11. In one aspect of the invention, cord mounts 92, 94, and 96 may be model 12-BS-1420 gripper cord mounts provided by Griplock Systems, Inc. of Carpinteria, Calif., though other types of cord mounts may be used depending upon the size and weight of the fixture 10. The cord mounts and the connecting hardware may be electrically insulated from plate 23. For example, insulating rings 100, for instance, plastic insulating rings, such as, rings made of GE Lexan® polycarbonate or its equivalent, may be used to electorally insulate cord mounts 92, 94, and 96 and fasteners 99 from plate 23. Insulating rings 100 may be positioned on both sides of plate 23 (see FIGS. 10 and 11) to insulate cord mounts 92, 94, and 96 and mechanical fasteners 99 from plate 23. Cords 14 may be conventional wire cables, for example, AG-16-87-xxx, AG-24-01-xxx, or AG-30-20-xxx galvanized cables provided by Griplock Systems, Inc., for example, depending upon the current required in cables 14, or a 1/16-inch nominal diameter galvanized wire, for example, model number 3EACO23801, provided from W.A.C. of China, or their equivalents.
The canopy cover 27 is design to mount to plate 23 to conceal the electronic components 25 and allow cords 14 to pass through the cover 27 so cords 14 can support ring 12 and/or ring 16. As shown in FIGS. 10 and 11 canopy cover 27 may be frusto-concial in shape, but may take any geometry shape, including circular cylindrical and polygonal cylindrical, while providing the desired functions. Cover 27 may be mounted to plate 23 by conventional means, for example, by means of mechanical fasteners. For in the aspect shown, cover 27 may be mounted to plate 23 by means of a plurality of brackets 102 mounted by fasteners 104 to the inside of cover 27, for example, nuts threaded to threaded studs mounted on cover 27. Brackets 102 are positioned and adapted to pass through recesses 106 in the edge of plate 23 and, when cover 27 is rotated, engage plate 27 to retain cover 27 on plate 23. The engagement of brackets 102 to plate 23 is typically reversible whereby brackets 102 may disengage plate 23 when cover 27 is rotated whereby brackets 102 pass through recesses 106.
Canopy cover 27 includes at least two, but typically, three, through holes 108 through which cords 14 can pass. As noted above, in one aspect, at least some of cords 14 may transmit electric power. Therefore, according to one aspect of the invention, in order to minimize the likelihood of electric shocks or shorts, cords 14 may be electrically insulated from cover 27, which may typically be metallic, by one or more insulators 110, for example, plastic insulators, for instance, GE Lexan polycarbonate insulators. As shown in FIGS. 10 and 11, aspects of the invention may include insulators 110 comprising insulating disks having a through hole positioned to pass cord 14 and mounted about through holes 108 to electrically insulate cords 14 from cover 27. Insulating disks 110 may be mounted to cover 27 with mechanical fasteners, for example, with fasteners 112, for example, nuts threaded to threaded studs mounted on cover 27.
