(78) The term “L.E.D.” is known in the art and relates to Light-Emitting Diode: a semiconductor diode that emits light when an electric current passes thru it as a result of a specific voltage applied to its terminals.
(79) The term “L.E.D. driver” is known in the art and relates to an electrical device that manages power and controls the current flow to an L.E.D. lighting source. The electrical device is connected to a power source.
(80) The term “driver enclosure” (abbreviated as D.E.4) is related to the L.E.D. driver enclosure, component 40 in our description, and is known in the art as the electrical enclosure housing the L.E.D. driver and constituting a part of the luminaire intended to: (a) reduce the risk of contact with live parts; (b) enclose electrical parts and components that can involve a risk of fire; (c) protect internal parts from mechanical damage; and (d) protect internal parts from the environment.
(81) The term “internal junction box” is an enclosure functioning as a compartment to separate the low voltage wiring circuit from the high voltage branch wiring circuit. The branch wiring compartment must be enclosed in a space with a minimum volume of 6 cubic inches, per U.L. standard 1598.
(82) The term “opening” should be construed per Underwriters Laboratories (U.L.) definition as “an aperture in an enclosure that is covered or filled by a plug or knockout and that has the potential of becoming an open hole”.
(83) The term “knockout” (abbreviated as K.O.) relates to a partially cut-out opening that is closed until the precut material is removed. A similar explanation should be related to the term “half-shear” that will be used in our detailed description of the invention embodiment.
(84) The term “heat sink” should be construed as a material of a particular shape intended to absorb excessive heat from a surface and dissipate that heat thru other surfaces.
(85) The term “countersink” should be construed as a conical hole cut into a manufactured object.
(86) The term “plaster” should be construed as “a mixture of lime or gypsum, sand, and water, sometimes with fiber added, that hardens to a smooth solid” and is used for coating walls and ceilings.
(87) The term “spackle” is a trademark referencing a compound used to fill cracks in plaster and produce a smooth surface.
(88) The term “spackle flange” is known in the art as that lighting fixture component that is placed in contact with architectural surfaces for the purpose of applying spackle on top of it and bonding the fixture housing to the architectural surface. Alternatively, in another embodiment, the term “covering and anchoring surface” is largely used in reference to the “spackle flange” component but it's not intended to be limited to that particular embodiment.
(89) The term “elbow fitting” is used in piping and electrical fittings to define a change of direction of an electrical conduit at a specific angle (usually 90 degrees).
(90) The term “hinge joint” is used in some embodiments of this invention to define an articulation that would allow motion only in one plane.
(91) For the purpose of this invention, the term “structure” is used in reference to the framework of a building such as an edifice for commercial, residential and industrial space or any other construction establishment.
(92) The term “stud” is known as a building material that is used to construct the frame of that structure.
(93) The term “recessed” is used, in this invention, to define a setback position of a component relative to a planar surface or a mounting surface.
(94) The term “channel” is used to reference an element having an elongated base, a first and a second wall, first wall disposed at a certain distance from the second wall, and extending from the base in a common direction therefore forming a cavity with two open ends.
(95) The abbreviation “H.V.W.C.3” meaning “High Voltage Wire Channel” is in reference to component 20 of the lighting fixture segment. Alternatively, in another embodiment, the features of component 13 are combined with the features of component 20 to form one piece construction and this new component would be named “channel with integral wire way chase”.
(96) The abbreviation “P.I.S./H.-L.E.” meaning “Power Input Segment/Housing for Light Engine” is in reference to component 53 of the lighting fixture segment; Alternatively, in another embodiment, the term “channel segment” is used in reference to component 53, within the scope of the invention, but not limited to that particular embodiment. The abbreviation “T-slot” represents a groove cut into a material, like aluminum, with a tool having the shape of letter ‘T’, like an extrusion tool.
(97) In an exemplary embodiment, a fastening method is employed to secure at least two components by interlocking their own features (fastening by shape) or by using intermediate fasteners like screws, clips, clasps, glue, etc.
(98) A “snap-fit” is a mechanical joint system where part-to-part attachment is accomplished with locating and locking features (constraint features) that are homogenous with one or the other of the components being joined. Joining requires the (flexible) locking features to move aside for engagement with the mating part, followed by return of the locking feature toward its original position to accomplish the interference required to latch the components together . . . “—The First Snap-Fit Handbook”, Bonenberger, 2000 is incorporated herein by reference. Some examples of locking features are: hooks, ridges, grooves, buttons, holes, depressions, indentations, etc.
(99) Descriptions of snap-fit joints can be found in US patent application no. US20070000922 A1 and U.S. Pat. No. 5,102,253 A incorporated herein by reference. Snap-fits joints advantageously eliminate other joining methods, e.g. screws, clips, and adhesives.
(100) For the purpose of this invention, the term “groove” is a long, narrow cut or depression, especially one made to guide motion or receive a corresponding ridge.
(101) For the purpose of this invention, the term “rib” is a long raised piece of stronger or thicker material across a surface or through a structure.
(102) The term “co-extruded” is used when more than one plastic material is pressed, in the same time, thru the same die, to produce a single piece part;
(103) For the purpose of defining directionality, a coordinate system needs to be related to an elongated segment of the lighting system having a light emitting surface normal to Z axis of a cartezian coordinate system while its length is defined in the X direction and its width in Y direction.
(104) In an exemplary embodiment, depicted in
(105) As illustrated by
(106) When a high voltage wire way channel H.V.W.C.3 is needed between the L.E.D. driver compartments, a “spackle flange/cover” version could be installed, as illustrated by
(107) In an exemplary embodiment, a gap of predefined shape might be formed in the planar surface similar to a concatenated sequence of “open” line segments with different angles between them. As seen in
(108) In an exemplary embodiment, as depicted in
(109) The surface 138 or 128 might be exposed or visible surfaces, in some configurations, therefore serving as a decorative surfaces, with a required finish. The protrusions 132 and 134 (respectively 122 and 124, or 912 and 914, or 922 and 924, or 982 and 984) could be one or multiple pairs intended to retain the lens 36 or other lens variations 39, while they are inserted into the channel housing. They are also designed to allow the removal of the lens while a thin object is inserted, between the lens and the housing, and acceptable force is applied on that object. The surface 133 (or 139) is a mounting surface for the L.E.D. light source 73. The top surfaces 131, 921 or 951 are visible from the room side therefore their alignment is important as they have to be perceived as continuous line independent of the number of fixtures that are in the row. The features 125, 915, 925, 955 or 205 could be described as a ‘T’ slot. This is intended as a receiver slot for corner cleats or alignment plates as those depicted in
(110) At the ends of the continuous row or on a standalone fixture we would install end caps. One exemplary embodiment, depicted in
(111) Another component of some lighting fixtures, especially those configurations with more than one D.E.4 in a row, is the high voltage wire way chase, item 20, as illustrated in
(112) Another component of the lighting fixtures, exemplified in
(113) Another component of the lighting fixtures, exemplified in
(114)
(115) In another embodiment of this invention, the spackle flange/cover 23 and the light diffusing element 36 could be formed as a single piece component.
(116) The light source 73 is primarily comprised of multiple L.E.D. The technology could employ blue, white, RGB L.E.D. chips. The electrical circuit could be embedded into soft strips, FR boards, OL.E.D.s or any other electroluminescent diode that is capable of generating radiation in response to an electrical signal.
(117)
(118) The wiring of the L.E.D. driver enclosure (D.E.4) could be done thru any opening on the back of the enclosure (“knockout” holes, access hole and cover plate, etc.) There could be one, two or more K.O. that could receive one, two or more elbow connectors, first being to feed the power wires, a second one to feed the control wires (for example the 0-10V wires). The K.O. could be removed by pushing against the round cap from inside with a screw driver or other object having a diameter smaller than the K.O. diameter and being capable to withstand the force necessary to push the round cap until removed. The D.E.4 could be made of aluminum sheet metal or steel. The elbow could be an off the shelf item usually made of metals (zinc, steel, etc.).
(119) Continuing description of features at
(120) On the back side of the driver enclosure we can see a set of small mounting K.O. arranged in any appropriate pattern to match the footprint of a series of L.E.D. drivers intended to be installed for every fixture configuration or by using intermediate mounting bracketing. The mounting of the driver depicted in the exemplary embodiment is not intended to restrict the other options that are not shown here as this driver could be installed on the other adjacent surfaces 408 or 409 of the driver enclosure D.E.4, as seen in
(121) The enclosure 40 is considered as being “recessed” and, together with the elbow connector 46, intended to fit within the “depth” limitation of a particular space, labeled “D1”, described in detail in application Ser. No. 14/810,714 incorporated herein by reference.
(122) In general, an enclosure is considered “sufficiently recessed” if its depth, measured from its mounting surface, is less than “D1” and its protrusions are equal or less than the thickness of the planar surface “D” plus the thickness of the plaster, if any. The plaster thickness is usually between 1 mm to 6 mm. In general, the materials that are used to manufacture the electrical enclosures and the wire way chase integral to a channel, are: metals (carbon steel, stainless steel, aluminum, etc.), thermoset polyesters (i.e. fiberglass), thermoplastic (i.e. polycarbonate, ABS, etc.), polyesters, fire retardant plastics, etc.

(126) The envelope of the fixture components installed on the framework that is supporting the architectural surface is defined as having the thickness of the respective surface, labeled “D” as illustrated by
(127) A section view thru the driver compartment of the lighting system is presented in
(128) The linear fixtures could be installed as semi-recessed configuration, where only the D.E.4 is recessed while the light engine housings are above the planar surface. Other configuration could be when the light engine housings are surface mounted (for example, using a clip 15 as seen in
