The disclosed embodiments relate to lighting for illuminating hardscape structures such as retaining walls.
Hard materials, such as masonry structures, used as a part of a landscape design are known commonly as “hardscapes.” A hardscape can incorporate structures such as pathways, steps, driveways, retaining walls and the like into an aesthetic installation generally, although not exclusively, in an outdoor setting which combines plant, masonry, and lighting elements to enhance the visual environment of a residence, commercial facility, or school campus, to cite but a few examples.
A hardscape may be formed of natural stone, bricks, or blocks manufactured from concrete, which are available in various colors, shapes and textures that simulate natural or quarried stone. Such products, for example, those provided by companies such as EP Henry of Woodbury, N.J., constitute structural systems that allow for the construction of structures such as retaining walls using discrete masonry elements that may be positioned atop one another to form a wall without the use of mortar. The structure, nevertheless, is a substantially permanent structure due to the weight, regular shape, friction and quasi-interlocking nature of the discrete elements.
Because lighting often is an important component of landscape design, it is desirable to incorporate lighting elements, such as lamps, into the design, and to provide the landscape designer with flexibility in configuring the lighting elements to produce an optimal lighting effect. Prior lamp designs for hardscape use are illustrated in U.S. Pat. No. 8,672,502, issued Mar. 18, 2014, the disclosure of which is incorporated herein it its entirety. While the devices shown therein have provided an improvement over prior devices, further improvements could provide added flexibility and control of the lighting effect, and better maintainability of the lamps.
Embodiments of lamps adapted for mounting on a structure formed from a plurality of discrete elements stacked one atop another can include a body having a plate. The plate includes a first portion, a second portion, a top side, and an underside. The first portion is configured to be positioned between at least two of the elements so that contact between the first portion of the plate and the discrete elements retains the lamp in position on the structure. The plate has a length and a width each being substantially larger than a thickness of the plate between the top side and underside.
The lamps also include a light fixture having a light source coupled to the body adjacent to an underside of the second portion of the plate. In one form, the light source is configured to rotate in relation to the body.
Embodiments of illuminated hardscape structures include a first discrete element, a second discrete element positioned atop the first discrete element, and a lamp. The lamp includes a body having a plate with a first portion, a second portion, a top side, and an underside. The first portion is positioned between the first and second discrete elements so that contact between the first portion of the plate and the first and second discrete elements retains the lamp in position on the structure. The plate has a length and a width each being substantially larger than a thickness of the plate between the top side and underside.
The hardscape structures also include a light fixture having a light source. The light fixture is coupled to the body adjacent to an underside of the second portion of the plate, and is configured to rotate in relation to the body.
Embodiments of lighting systems adapted for mounting on a structure formed from a plurality of discrete elements stacked one atop another include a mount having a first portion with an upper surface and a lower surface, and a second portion with an upper surface and a lower surface. The lower surface of the first portion faces the upper surface of the second portion. The first and second portions are configured to be positioned at least in part between two or more of the discrete elements.
The lighting systems also include a lamp having a body with a plate. The plate has a top side; an underside; and a first portion configured to be positioned at least in part within the mount so that the lamp is retained in position on the mount between the first and second portions of the mount. The plate has a length and a width each being substantially larger than a thickness of the plate between the top side and underside.
The lamp also has a light fixture that includes a light source. The light fixture is coupled to the body.
The invention also provides a lighting system adapted for mounting on a structure formed from a plurality of discrete elements stacked one atop another, which lighting system includes a mount and a lamp having a body configured to be removably retained within the mount. The mount includes a first portion having an upper surface and a lower surface, and a second portion having an upper surface and a lower surface. The lower surface of the first portion faces the upper surface of the second portion, and the first and second portions of the mount are configured to be positioned at least in part between two or more of the discrete elements. The lamp includes a body that includes a plate having a top side an underside and a first portion configured to be receivable at least in part within the mount and removably retained therein between the first and second portions of the mount. The light fixture includes a light source and is coupled to the body.
The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate the presently preferred embodiments of the invention, and, together with the general description given above and the detailed description given below, serve to explain the features of the invention. In the drawings:
The body also includes a flange 20 attached to the plate 14. The flange 20 can be formed integrally with the plate 14, and can be bent or molded into the angular orientation shown in the figures. Alternatively, the flange 20 can be formed separately from the plate 14, and affixed to the plate 14 via mechanical, welding, or other suitable means. The flange 20 is preferable a substantially right angle flange, i.e., the flange is oriented substantially transverse to the underside 18 of the plate 14. The flange 20 can be oriented at virtually any angle relative to the plate 14 in alternative embodiments.
The flange 20 includes an elongated front panel 22 and side panels 24 as shown in
A decorative faceplate (not shown) can be attached to the body 12 in alternative embodiments. The faceplate can be configured to overlay an outwardly-facing surface 30 of the flange 20. The faceplate can be attached to the flange 20 via fasteners, such as screws; adhesives, brazing, and welding can be used in the alternative. It is advantageous to make the body 12 and the faceplate from robust materials such as metal that can withstand the effects of weather. Accordingly, the body 12 and faceplate may be formed, for example, from aluminum or stainless steel to prevent corrosion. If a decorative effect is desired, the body 12 and faceplate, or portions thereof, may be formed from, for example, copper or brass. Plastics and fiber reinforced composites can also be used, as well as a combination of metals, resins, plastics, synthetic stones, and other materials.
The lamp 10 further includes a light fixture 32, and a mounting bracket 34. The light fixture 32 is mounted on an elongated major portion 36 of the mounting bracket 34 using bolt and nut fasteners 38 as shown in
The light fixture 32 includes a circuit board 40, a light source 42 mounted on the circuit board 40, and other electrical components for the light circuit as known in the art. The illustrated light source 42 is formed of two square arrays of LEDs having parallel circuitry, as shown in
The above details of the light fixture 32 are presented for exemplary purposes only. The light fixture 32 can have other configurations in alternative embodiments. For example, alternative embodiments of the light fixture 32 can include less, or more than two arrays of LEDs; or can incorporate a light source other than LEDs, such as incandescent or halogen bulbs accommodated by one or more light sockets.
The mounting bracket 34 can be formed from a durable, rigid material suitable for outdoor use, such as stainless steel or aluminum. Plastics and fiber reinforced composites may also be used, as well as a combination of metals, plastics and other materials. The mounting bracket 34 has mounting tabs 50 that are attached to, and extend from opposing ends of the major portion 36, as shown in
The mounting bracket 34 and the attached light fixture 32 are mounted for rotation relative to the body 12 by way of the mounting tabs 50. The mounting bracket 34 is sized so that an end portion 52 of each mounting tab 50 is located adjacent to an associated one of the side panels 24, and is spaced apart from the side panel 24 with minimal, or no clearance as shown in
The mounting bracket 34 and the light fixture 32 can rotate between a first position depicted in solid lines in
A user can adjust the area of illumination provided by the light fixture 32 by loosening the screws 54 to permit rotation of the mounting bracket 34, and then tightening the screws 54 once the mounting bracket 34 and the light fixture 32 have been rotated to a desired angular position. Alternatively, the mounting bracket 34 can be mounted with sufficient function to maintain whatever position it is in after being rotated to the desired angle, such as by use of a tight screw.
The front panel 22 and the side panels 24 of the flange 20 shield the light fixture 32 from view, at least partially, while permitting the light generated by the light fixture 32 to illuminate the area below the lamp 10. The angled orientation of the lower edge 26 of each side panel 24 helps to shield the light fixture 32 from view when the light fixture 32 is in, or near, its second position.
As shown in
The ability to rotate the light fixture 32 permits a user to aim the light generated by the light fixture 32 so as to produce a desired visual effect on the hardscape 72 and the surrounding area. For example, when the light fixture 32 is in the first position depicted in solid lines in
The lamps disclosed herein provide a simple and elegant illumination for hardscape design that is easy to install and maintain. Such lamps are readily removable and repositionable and facilitate repair or reconfiguration of the hardscape as required. They may be used with any form of hardscape, for example, concrete products such as blocks or bricks, natural stone, mortared or stacked structures, wooden structures such as decks and retaining walls made from railroad ties to cite but a few exemplary applications. The ability to adjust and aim the light fixtures of the lamps provides added flexibility in optimizing the spread of the light produced by the lamps for aesthetic, safety-related, or other purposes.
In addition to being used on a stand-alone basis as described above, the lamps 10, and variants thereof, can be incorporated into a lighting system 100 as depicted in
The lamp 10a is substantially identical to the lamp 10 as described above, with the exception of the manner in which the power line 44 of the lamp 10a is connected to the light fixture 32, which is discussed below. Components of the lamp 10a that are identical, or substantially identical to those of the lamp 10 are denoted herein, and in the drawings, by identical reference characters. The use of the lamp 10a in connection with the lighting system 100 is disclosed for exemplary purposes only. The lighting system 100 can be equipped with other types of lamps that are capable of mating with the mount 102 in the below described manner, including the lamp 10, and lamps that do not have a rotatable light fixture such as those shown in the U.S. Pat. No. 8,672,502. In addition, the lamp 10a can be used on a stand-alone basis, i.e., without the mount 102.
The mount 102 is configured to be mounted between two or more of the discrete block-like elements 60 of a hardscape structure such as a retaining wall 58a shown in
Referring to
The lip 108 extends downwardly from a forward edge of the second portion 106, from the perspective of
The second portion 106 includes two tabs 126, as depicted in
The mount 102 can be formed from a durable, rigid material suitable for outdoor use, such as stainless steel or aluminum, and should be sufficiently resilient to hold the plate 14 in place. Suitable plastics and fiber reinforced composites may also be used, as well as a combination of metals, plastics and other materials. The mount 102 can be unitarily formed, i.e., the mount 102 can be formed from a single sheet of material which can be bent so as to define a folded, or third portion 130 that adjoins the first portion 104 and the second portion 106. In addition, the sheet can be folded along a fold line 132 to form the lip 120. Cutouts can be formed in the sheet before it is bent to define the tabs 124.
The bending of the sheet to form the lip 108 results in a relatively small radius “r2” between the lip 108 and the second portion 106, as can be seen in
The third portion 130 is substantially C-shaped, and has a radius “r1” as shown in
The first portion 62 of the plate 14 is received between the first portion 104 and the second portion 106 of the mount 102, as shown in
Once the first portion 62 of the plate 14 has been inserted into the mount 102, the lower surface 112 of the first portion 104 and the upper surface 114 of the second portion 118 are urged toward the respective top side 16 and underside 18 of the first portion 62, due to the bias of the third portion 130 on the first and second portions 104, 106, and may also be urged by the weight of the retaining wall or other structure located above the mount 102. The lamp 10a is retained in the mount 102 by the resulting friction between the top side 16 of the first portion 62 of the plate 14 and the lower surface 112 of the first portion 104 of the mount 102; and between the underside 18 of the first portion 62 of the plate 14 and the upper surface 114 of the second portion 106 of the mount 102.
The lamp 10a includes a light fixture 32a, shown in
The lighting system 100 can be integrated into a hardscape structure such as an illuminated hardscape 72a formed from a retaining wall 58a shown in
The mount 102 can be installed on the retaining wall 58a preferably as the retaining wall 58a is being constructed. Installation is performed by placing the mount 102 on top of one (or more) of the block-like elements 60 whose upper surface coincides with the desired height for the lamp system 100, so that the lower surface 116 of the second portion 106 rests on the upper surface of the block-like element 60 and the lip 108 abuts the outwardly-facing surface of the block-like element 60.
The mount 102 can be secured to the underlying block-like element 60 using fasteners (not shown) anchored to the element 60 by way of the holes 128 formed in the tabs 126. Alternatively, the mount 102 can be secured using adhesive placed, for example, on and under the tabs 126, and within the holes 128. Once the mount 102 has been secured and the power line 44 for the light fixture 32a has been routed through the adjacent block-like elements 60 to the earth or fill behind the blocks 60, another of the block-like elements 60, such as a top or cap block 74, can be placed on top of the mount 102, so that the bottom surface of the block-like element 60 rests on the upper surface 110 of the first portion 104 of the mount 102. When installing the overlying block-like element 60, the lamp 10a should be fully inserted in the mount 102 as shown in
Once the retaining wall 58a has been completed, the mount 102 is retained on the retaining wall 58a by fasteners through the tabs 126, mortar, and/or friction between the mount 102 and the adjacent block-like elements 60.
Alternatively, the mount 102 and lamp 10a can be retrofitted into the retaining wall 58a after the retaining wall 58a has been constructed. The mount 102, with the lamp 10a inserted therein, can be inserted between two or more of the block-like elements 60, until the lip 108 of the mount 102 abuts the block-like element or elements 60 located directly below the mount 102.
The mount 102 also can be integrated into a hardscape structure such as a staircase 80a shown in
The configuration of the mount 102 permits the lamp 10a to be removed from, and reinstalled in the retaining wall 58a and the staircase 80 quickly and easily, without any disassembly of the retaining wall 58a or the staircase 80. To remove the lamp 10a, the user merely needs to pull the lamp 10a away from the retaining wall 58a or the staircase 80, so as to overcome the friction between the contacting surfaces of the mount 102 and the first portion 62 of the plate 14, at which point the first portion 62 can be slid out from between the first portion 104 and the second portion 106. The power line 44 can be disconnected in the above-discussed manner before the lamp 10a is pulled away from the mount 102 to avoid disturbing the power line 44, which is permanently routed within or along the retaining wall 58a in a typical installation.
To reinstall the lamp 10a, or a new lamp 10a, the user places the free end of the first portion 62 of the plate 14 between the first portion 104 and the second portion 106, and pushes the lamp 10a inwardly, i.e., toward the retaining wall 58a or the staircase 80. The curvature between the lip 108 and the second portion 106 resulting from the radius r2 may help to guide the end of the first portion 62 between the first portion 104 and the second portion 106, and encourages the first portion 104 to separate from the second portion 106 to accommodate the plate 14 therebetween. The lamp 10a is pushed inwardly until the rearward-facing ends of the side panels 24 of the lamp 10a abut the retaining wall 58a or the staircase 80. Further inward movement is preferably prohibited at this point by interference between the side panels 24 and the retaining wall 58a or staircase 80. The power line 44 can be reconnected in the above-discussed manner before or after the lamp 10a has been inserted into the mount 102 depending on the configuration of the wire.
The use of the mount 102 thus permits the lamp 10a to be repaired or replaced without any disassembly of the retaining wall 58a or the staircase 80a. In addition, the ability to disconnect the light fixture 32a from the power line 44 makes it possible to replace the light fixture 32a with disturbing the power line 44 from its installed position within or along the retaining wall 58a or the staircase 80.
