Definitions
- the present invention relates to a lighting fixture. More particularly, the invention is directed to an elongate modular, lineally-extending light fixture for ceiling, wall, corner and row-mount mounting, and to the method of fabrication of such a fixture.
- the present invention is offered to provide a high-quality lighting fixture to meet and to fulfill a perceived need—a need believed not heretofore to have been completely appreciated or fully satisfied.
- the need referred to is of a lighting fixture of readily adjustable length and physical configuration, and adaptable fully to traverse and completely to fill any required or desired lineal as well as areal expanse.
- the present invention effectively meets the challanges posed—and in an artistically pleasing mode, while obviating shortcomings and inadequacies of prior art lighting fixtures.
- principal realized aims of the present invention are to confront, to meet and to eliminate such inadquacies and shortcomings, and to provide simple yet remarkably effective solutions to the problems posed.
- the lighting fixture of the present invention may be characterized as “selectably extendable and angularly directable “linear” lighting”. It is a critical feature of the present invention that it constitutes one or more generally tubular “modules”, sections, or housing components, these being joined to one another at end portions or segments thereof.
- the structure thus produced constitutes, in a principal embodiment thereof, a lineal array, of selectable length or lineal expanse—as required or desired.
- lineal sectors or sections of the lighting fixture may be oriented with respect to one another to provide various different “geometric” configurations or shapes. These accommodate direction change modes or related needs.
- the fixture may consist of two lineal arrays connected at ends thereof to define a 90 degree juncture or corner.
- three linear arrays of the modules of the fixture may be connected to form a T node or configuration.
- a specially designed cross-connector or coupler is provided to define and constitute a joinder structure in which four separate and distinct lineal sectors of a fixture are interconnected or functionally joined as an X type mode to extend at 90 degrees to one another.
- the modular sections include extrusions constituting high-strength metal alloys such as aluminum alloys.
- the extrusions define a principal support element of each housing section or module.
- the metal extrusion takes the physical form of an elongate, generally flat base integrally joined at a pair of opposed longitudinal edges thereof to upwardly-directed sidewalls.
- the sidewalls of the extrusion are—or the side walls of each extrusion are—integrally formed at opposed respective upper elongate edge portions thereof with channel-like upwardly opening grooves or slots. These serve matingly to receive therewithin laterally-spaced elongate free edge portions of a lens of a high-strength plastics composition.
- gaskets which include die-cut gaskets, which extend along a lineal expanse of the plastics lens for establishing a fluid-impervious seal.
- the gasket is seated in an elongate groove formed adjacebt a free edge portions of the lens.
- the lens which defines and controls distribution of illuminating light emanating from the fixture, is composed of a high-impact, shock-resistant plastics composition including acrylic plastics and polycarbonate plastics.
- Yet another feature of the configuration of a preferred embodiment of the plastics lens is that it is formed to define along each extending edge thereof with an angled flange for overlying an edge of the coextensive extruded base of the housing or body section.
- the lens coextensive with the lineally extending extruded metal base, bridges opposed side walls of the extruded metal base to complete a generally tubular lighting fixture housing section which is open at each end.
- the metallic extrusion and the lens mounted therealong and sealingly coupled thereto may be of any selectable length or lineal expanse in the fabrication of a specific module, in accordance with the present invention.
- a further important physical component of each elongate modular section of the lighting fixture is an endplate mounted on the housing-like body section coaxially therewith at each end thereof.
- the end plate constitutes a casting formed of a metallic composition or alloy.
- the end plate is formed at an inner face thereof with an outwardly opening slot or groove extending along a bounding coextensive edge zone thereof for accepting therewithin, in mating and sealing engagement therewith, the extruded metallic base component of the housing and the surmounting plastics lens thereof.
- the end plate is configured to define an end face contoured for mounting thereon and affixing thereto, selectively, either an end cap for capping and closing the housing of the modular structure, or a ring in the form of a band-like coupler.
- the coupler is configured for sealingly mounting on the end plate of the housing for joining the end of the housing section to an end plate of a second housing body of a second modular housing section of the lighting fixture so that the sections are sealingly joined to one another endwise.
- the end cap of a preferred embodiment of the invention is integrally formed with a circumambient, outwardly-projecting, flange-like edge portion configured to overlie, in sealing engagement therewith, a perimetric shoulder circumscribing an outwardly presented face of an end plate attached to the housing.
- each is skeletal in construction with a plurality of through openings or passageways or runs, commonly called “raceways”.
- the latter accommodate the passage and extension therethrough of wires and electrical fixture components for traversing the lineal expanse of the modular housings of the lighting fixture, through each end-joined lineal section thereof.
- the elongate body or housing may constitute an elongate array of any selectable number of “modules” or body sections, functionally to traverse any given or intended expanse.
- the individual, end-abutting sectors or housing sections of the lighting fixture of the invention establish therewithin and along an entire expanse thereof uninterrupted passageways. These include raceways for accommodating wires, cables and the like. The latter are effectively isolated from ballasts and lamp wires. It is significant that, in accordance with the practice of the present invention, there are provided physical barriers establishing and effectively separating, two isolated raceways. These are in addition to a passageway for the ballast power feed wires.
- the described, exceedingly significant and important physical structural arrangement is highly desirable.
- the structural arrangement and configuration of the fixtures of the present invention, as described facilitate, effectuate and ensure important and critical physical separation of high voltage and low voltage wiring.
- the “utility” and versatility of the fixtures of the present invention are thus signifigantly and materially enhanced.
- the items (and “features”) which may be safely housed in an “isolated” raceway such as that contained in the fixtures of the present invention are 24-volt alarm circuitry, such as a fire alarm; fibre optic network cables; a thermostat wire; telephone wires; etc.
- the capabilities outlined above are capabilities provided in the present invention. They are believed to be capabilities unique in lighting fixtures of the ““general type” in which the lighting fixtures of the present invention may customarily be grouped or “classified’.
- Yet another feature of the invention is that although it may be especially advantageous and convenient to fabricate all of the modular body sections of the lighting fixture are all of the same length. Such arbitrary “uniformity” is in no sense a requirement.
- individual luminaires may be nominally 8′′ ⁇ 24′′, 8′′ ⁇ 48′′, or 8′′ ⁇ 60′′. Other embodiments maybe nominally 12′′ ⁇ 24′′. 12′′ ⁇ 48′′. or 12′′ ⁇ 60′′.

Abstract
A lighting fixture which includes an elongate modular lineal section fabricated of an extruded high-strencth metal alloy. The extrusion comprises an elongate generally flat base integrally joined at a pair of opposed lingitudinal edges thereof to upwardly extending sidewalls. The sidewalls are formed at opposed respective upper edge portions thereof with channel-like upwardly opening grooves for matingly receiving therewithin laterally spaced elongate free edge portions of a lens of a high strength plastics composition. The lens bridges opposed sidewalls of the extruded metal base to complete a lighting fixture housing section or module open at each end. Configured for matingly engaging and for positive attachment to each end of the housing section is a skeletal bridge-like end plate formed with through framed openings. Attachable to each or to either end plate is a skeletal adapter ring for facilitating attachment of an additional housing section or module to provide a lighting fixture comprised of two or more modular housing sections. End caps provide fluid-tight closures of the assembly. In other embodiments of the invention the modular structures may be connected to provide lighting fixtures which form L, T, cross, X, as well as closed-loop configurations.
Description

- Many different types of lighting fixtures, including elongate fixtures for various applications and locations are known in the art. Such fixtures have been installed for general illumination in stores, offices, supermarkets, schools, hospitals, banks and other interior and outside areas. Appreciating the versatility of such lighting fixtures, including the many engineering designs and configurations heretofore devised and adopted, there appears still to remain a real need for still another versatile, specially-adaptable lighting fixture to facilitate and enhance particular applications.
- It is a particular aim of the present invention to provide an exceedingly simple yet readily-adaptable and adjustable such lighting fixture. The present invention is offered to provide a high-quality lighting fixture to meet and to fulfill a perceived need—a need believed not heretofore to have been completely appreciated or fully satisfied.
- The need referred to is of a lighting fixture of readily adjustable length and physical configuration, and adaptable fully to traverse and completely to fill any required or desired lineal as well as areal expanse. The present invention effectively meets the challanges posed—and in an artistically pleasing mode, while obviating shortcomings and inadequacies of prior art lighting fixtures. Thus, principal realized aims of the present invention are to confront, to meet and to eliminate such inadquacies and shortcomings, and to provide simple yet remarkably effective solutions to the problems posed.
- In a “descriptive” sense the lighting fixture of the present invention may be characterized as “selectably extendable and angularly directable “linear” lighting”. It is a critical feature of the present invention that it constitutes one or more generally tubular “modules”, sections, or housing components, these being joined to one another at end portions or segments thereof. The structure thus produced constitutes, in a principal embodiment thereof, a lineal array, of selectable length or lineal expanse—as required or desired. Alternatively, lineal sectors or sections of the lighting fixture may be oriented with respect to one another to provide various different “geometric” configurations or shapes. These accommodate direction change modes or related needs.
- Among these optional configurations is an essentially in lineal or straight line array of any desired expanse. Alternatively, the fixture may consist of two lineal arrays connected at ends thereof to define a 90 degree juncture or corner. Also, through the use of yet another special connector, three linear arrays of the modules of the fixture may be connected to form a T node or configuration. In yet another physical arrangement, a specially designed cross-connector or coupler is provided to define and constitute a joinder structure in which four separate and distinct lineal sectors of a fixture are interconnected or functionally joined as an X type mode to extend at 90 degrees to one another.
- An important structural feature of the invention is that the modular sections include extrusions constituting high-strength metal alloys such as aluminum alloys. The extrusions define a principal support element of each housing section or module. In a preferred embodiment of the invention the metal extrusion takes the physical form of an elongate, generally flat base integrally joined at a pair of opposed longitudinal edges thereof to upwardly-directed sidewalls.
- In a preferred embodiment of the invention the sidewalls of the extrusion are—or the side walls of each extrusion are—integrally formed at opposed respective upper elongate edge portions thereof with channel-like upwardly opening grooves or slots. These serve matingly to receive therewithin laterally-spaced elongate free edge portions of a lens of a high-strength plastics composition.
- It is an important feature of the invention that there are provided gaskets, which include die-cut gaskets, which extend along a lineal expanse of the plastics lens for establishing a fluid-impervious seal. Conveniently, the gasket is seated in an elongate groove formed adjacebt a free edge portions of the lens.
- It is a feature of the invention that the lens, which defines and controls distribution of illuminating light emanating from the fixture, is composed of a high-impact, shock-resistant plastics composition including acrylic plastics and polycarbonate plastics.
- Yet another feature of the configuration of a preferred embodiment of the plastics lens is that it is formed to define along each extending edge thereof with an angled flange for overlying an edge of the coextensive extruded base of the housing or body section.
- It will be understood that the lens, coextensive with the lineally extending extruded metal base, bridges opposed side walls of the extruded metal base to complete a generally tubular lighting fixture housing section which is open at each end. It will be appreciated as well that the metallic extrusion and the lens mounted therealong and sealingly coupled thereto may be of any selectable length or lineal expanse in the fabrication of a specific module, in accordance with the present invention.
- A further important physical component of each elongate modular section of the lighting fixture is an endplate mounted on the housing-like body section coaxially therewith at each end thereof.
- n preferred embodiments of the invention, the end plate constitutes a casting formed of a metallic composition or alloy. The end plate is formed at an inner face thereof with an outwardly opening slot or groove extending along a bounding coextensive edge zone thereof for accepting therewithin, in mating and sealing engagement therewith, the extruded metallic base component of the housing and the surmounting plastics lens thereof.
- It is a very significant feature of the invention that at its opposite sides the end plate is configured to define an end face contoured for mounting thereon and affixing thereto, selectively, either an end cap for capping and closing the housing of the modular structure, or a ring in the form of a band-like coupler. The coupler is configured for sealingly mounting on the end plate of the housing for joining the end of the housing section to an end plate of a second housing body of a second modular housing section of the lighting fixture so that the sections are sealingly joined to one another endwise.
- It will be understood that irrespective of the partucular number of lineally extending, joined modular body sections in a given installation, ends of each fixture terminate in a fixture-secured end cap fastened on a supporting end plate.
- The end cap of a preferred embodiment of the invention is integrally formed with a circumambient, outwardly-projecting, flange-like edge portion configured to overlie, in sealing engagement therewith, a perimetric shoulder circumscribing an outwardly presented face of an end plate attached to the housing.
- It is yet another important structural feature of the cast end plate of the coaxial cast coupler ring that each is skeletal in construction with a plurality of through openings or passageways or runs, commonly called “raceways”. The latter accommodate the passage and extension therethrough of wires and electrical fixture components for traversing the lineal expanse of the modular housings of the lighting fixture, through each end-joined lineal section thereof.
- It is an exceedingly significant capability and attribute of the lighting fixture of the invention that the elongate body or housing may constitute an elongate array of any selectable number of “modules” or body sections, functionally to traverse any given or intended expanse.
- Physically, the individual, end-abutting sectors or housing sections of the lighting fixture of the invention establish therewithin and along an entire expanse thereof uninterrupted passageways. These include raceways for accommodating wires, cables and the like. The latter are effectively isolated from ballasts and lamp wires. It is significant that, in accordance with the practice of the present invention, there are provided physical barriers establishing and effectively separating, two isolated raceways. These are in addition to a passageway for the ballast power feed wires. The described, exceedingly significant and important physical structural arrangement is highly desirable. The structural arrangement and configuration of the fixtures of the present invention, as described, facilitate, effectuate and ensure important and critical physical separation of high voltage and low voltage wiring. The “utility” and versatility of the fixtures of the present invention are thus signifigantly and materially enhanced.
- Among the items (and “features”) which may be safely housed in an “isolated” raceway such as that contained in the fixtures of the present invention are 24-volt alarm circuitry, such as a fire alarm; fibre optic network cables; a thermostat wire; telephone wires; etc. The capabilities outlined above are capabilities provided in the present invention. They are believed to be capabilities unique in lighting fixtures of the ““general type” in which the lighting fixtures of the present invention may customarily be grouped or “classified’.
- Yet another feature of the invention is that although it may be especially advantageous and convenient to fabricate all of the modular body sections of the lighting fixture are all of the same length. Such arbitrary “uniformity” is in no sense a requirement. Conveniently, individual luminaires may be nominally 8″×24″, 8″×48″, or 8″×60″. Other embodiments maybe nominally 12″×24″. 12″×48″. or 12″×60″.

- In accordance with the present invention, the aims and objects are achieved by providing a lighting fixture comprised of either a single module of selectable length, or alternatively, a plurality of modular sections, sectors, or housing sections joined to one another endwise as a lineal or in-line array. The method is readily effective to provide a lineal lighting fixture of any desired or required expanse. Many other embodiments of the invention are possible. Modular lineal sections maybe coupled at joined ends thereof to extend normally to one another to define a right-angle corner. Others may be connected by means of a T-shaped coupler to form a “T”. Still other modular sectors, of selectable lengths, may be connected to form an “X” or a cross.
- The housing sections themselves, which may be of any practical selectable lengths, each have end plates attached thereto. The end plates are presented to face one another. Finally, the end plates of two linearly adjacent housing sections are brought matingly to engage a lineally interposed coupling ring, thus to effect a sealed joinder of the two adjacent housing modules or housing sections of the lighting fixyure, one to the other.
- Referring now to the drawings, for purposes of disclosure and not in any limiting sense, preferred embodiments of the lighting fixture of the invention are shown in FIGS. 1, 2 and3 in the form of a
fixture 20 constituting a single module or modular housing section or component 24 (in FIG. 1), and afixture 30 having two modules or housing sections 24 (in FIG. 2). The twohousing sections 24 of theFixture 30, as shown in FIG. 2 are secured to one another endwise at respective facingend plates 34 thereof (FIGS. 3 through 8), by means of a coupler ring 40 (FIGS. 2, 4 and 8) interposed between respective end portions of a pair of identical housing portions ormodules 24. - Each fixture is shown in FIGS. 1 and 2 as securedly mounted at respective generally
planar bases 48 thereof to aceiling structure 50. Free ends ofhousings 24 are sealed at surmountingend plates 34 thereof with fittedend caps 52. The latter abut and are secured to, to overlie themounted end plate 34. (FIG. 3). Eachhousing section 24 of the fixture of the invention includes opposed lineally extendingside walls bases 48 at elongate upperedges 64 and 66 thereof (FIG. 3). - Referring further to FIGS. 1 and 2, disposed to extend along and joined at opposed longitudinally extending lower
free edges sidewalls like lens 80. Thelens 80 which bridges between opposed elongatefree edges sidewalls housing 24, is integrally formed along a co-extensive lineal expanse thereof with upwardly-directedflanges 86 and 88 to seat within downwaredly-opening elongate grooves orslots opposed edge zones sidewalls sidewalls like strips strips plates - As shown in FIG. 9, a
die cut gasket 120 is interposed sealingly to engage thestrips - Referring now further to FIGS. 3 through 6, the body of the
housing 24 carries at each end thereof, in fixed and secured engagement therewith, anend plate 34 constituting a high-strength casting of a metal composition, preferably a casting composed of a lightweight metal, such as an alloy of aluminum. As shown in FIGS. 3 and 4, theend plate 34 is a unitary structure constituting an integrally-formed, plate-like structure which is skeletal in configuration. The casting 34 has a plurality of through openings orpassageways body 142 thereof to provide wire ways and to facilitate passage therethrough of lighting tracks, conductive wires, illuminating sources and other electrical components and related structures. Surmounting theend plate 34 is a top flange 148 which extends contiguously and coextensively along a top end edge of thebase 48 of thehousing 24 in sealing engagement therewith. Integrally formed with and co-extensive with thetop flange 48 and stepped downwardly with respect thereto is asecond flange 152. - Referring further to FIG. 3, the
end cap 52 is integrally formed with aflange 156 projecting outwardly along a top,free edge 158 thereof. As indicated schematically, when theend cap 52 is positioned in place to mate with and close the end of thehousing 24, thetop flange 156 of theend cap 52 is brought to overlie and to effect a sealing engagement with theflange 152 of thehousing 24. At the same time an arcuate lower flange 162 of theend cap 52 engages and seals with a cooperatinglower flange 164 of theend plate 142. Theend plate 130 is positively secured to the end of thehousing 24 by means ofscrews 166 and 168. - As also shown in FIG. 3, the
end cap 52 is integrally formed withconnector posts end cap 52 from the interior of theend wall 176 at opposed upper corners thereof. Athird connector post 180, also integrally formed with theend cap 52, also projects inwardly from the interior of theend wall 176 at a central lower zonal area thereof. As depicted schematically in FIG. 3, when thecap 52 is positioned in place, the free ends of theposts bores end plate 34. - Referring further to FIGS. 3, 4 and5, the
end plate 34 is formed, on the interior of the opposedupper side sectors arcuate section 196 thereof, with anuninterrupted channel 200. Thechanel 200, which opens outwardly, is contoured, configured and sized for receiving in close and sealing engagement therewithin theopposed edge portions sidewalls lens 80 of thehousing 24. - Referring to FIGS. 2 and 5-8, embodiments of the lighting fixtures of the invention which include two or more housing sections or
modular components 24 joined endwise as a continuous uninterrupted physical structure (FIG. 2) include a coupler or coupler ring 40 (FIG. 4). The latter has generally the contour and form of theend plate 34 of the fixtures and is preferably, as in theend plate 34, also a metal casting of an aluminum alloy. As in the case of theend plate 34, thecoupler ring 40 is formed with a plurality of throughopenings end plate 34 and in through registry therewith when theend plate 34 and thecoupler ring 40 are used together—one with the other in an assembled lighting fixture having a plurality of body sectors ormodules 24. - The
coupler ring 40 has a circumscribing body contour which corresponds in material respects to the perimetric contour of theend plate 34, as shown in FIGS. 5 and 6. At a transversly extending generally planartop surface 220 and at a continuing integrally-formed arcuate bottom surface thereof, thecoupler ring 40 is integrally formed with a flange-liketop wall 220 extending laterally of thebody 224 at each of opposed sides thereof effectively to provide two opposed co-extensive over-hanging flanges. The flange-liketop wall 220 is operative to overlie in closely contacting engagement therewith a downwardly displaced or steppedco-extensive flange 152 of anend plate 34. Theend plate 34 is secured to the body orhousing module 24 of the fixture of the invention as previously described. In the manner explained, asecond housing component 24 may be fastened, at itssecured end plate 34 at the opposite, co-extensive second part of theflange 220 thus to effect a coupling of twohousing sections 24 to one another endwise. In the manner described, it becomes simple and quick to produce a row-mount lighting fixture having a selectable number of separate housing sections—each itself being in turn of a selectable length. Thus, one may readily generate a lighting fixture of any final overall length, as may be required or desired. - Referring now to FIGS. 10, 11, and12, it is within the purview and scope of the present invention that it includes lighting fixtures which are not limited to extending along or to traverse a straight line only. Rather, other geometric configurations of the lighting fixture have proven feasible and practical. For example, referring first to FIG. 10, there is shown a fragmentary view of a unitary lighting fixture of the invention constituting two
modular sections 24 oriented to extend normally to one another. There is provided a generallyrectangular connector 230 to a pair ofadjacent sides modular sections 24 are abuttingly and sealingly joined to form a corner assembly. The resulting fixture, which assumes an L shape, is suited for accommodating sharp bends, and for corner installations. - A second example of a non-linear embodiment of the fixtures of the present invention is illustrated in FIG. 11. As shown, there is provided a generally rectangular connector240 to respective three
sides 242, 244 and 246 of which three separatemodular sections 24 of the fixture are connected. The assembled fixture thus assumes a T configuration. - Yet another embodiment of the invention is depicted in FIG. 12. As shown, there is provided a four-sided
rectangular connector 250 to each side of which anend fixture section 24 is joined. There results a fixture having a cross or X-like configuration. It will be appreciated that, in accordance with the teachings of the present invention, through the use of appropriate selectable connectors, closed loop lighting fixtures embodying the principles and features of the invention may also be provided.
