DETAILED DESCRIPTION OF THE EMBODIMENTS

(12) FIGS. 1 and 2 show a lamp 10 integrable into a hardscape structure for illumination. Lamp 10 comprises a plate 12 having a flange 14 attached thereto. Plate 12 has a top side 13 and an underside 15. Flange 14 may be integral with the plate and oriented transversely to the plane 16 of the plate. A right angle flange is shown, but it is understood that the flange could be oriented at virtually any angle relative to the plate. A light fixture 18 is attached to the plate 12. In the embodiment shown in FIG. 2, the light fixture is attached to plate 12 by way of flange 14, although it could also be attached directly to the plate as shown in FIG. 3. Light fixture 18 provides a socket 20 that receives a bulb 22. The fixture may be mounted using a bracket 24 that is attached using a fastener 26, such as a rivet. Bracket 24 may also be attached in other ways, such as with adhesives, by welding as well as brazing. An electrical power line 28 extends from the fixture, the power line being connectable to a source of electrical power, such as a transformer, as described below. The bulb 22 can be of any suitable type, including LED type light sources.

(13) As best illustrated in FIG. 1, a decorative face plate 30 may be attached overlying a surface 14a of the flange 14, the surface 14a facing away from plate 12. The light fixture 18, when attached to the flange, is attached to the opposite surface 14b shown in FIG. 2. Attachment of the face plate to the flange is via fasteners 32, such as screws. Adhesives, brazing and welding are also feasible attachment methods. Side panels 34 may be mounted at opposite ends of the face plate 30. Together the face plate, flange and the side panels help direct illumination from the bulb 22 in a direction downwardly along the hardscape on which the lamp is mounted.

(14) FIG. 4 illustrates another embodiment 36 of the lamp according to the invention. Lamp 36 comprises a plate 12 to which a light fixture 18 may be attached, either directly or via a flange 14 as shown. In this embodiment, side panels 34 are positioned at opposite ends of flange 14. The flange and the side panels cooperate to direct light from the bulb 22 in fixture 18 downwardly along the hardscape on which the lamp is mounted. The flange may be integrally formed with the plate and bent or molded into the angular orientation desired. Likewise, the side panels may be an integral part of the flange bent or molded into an angular orientation.

(15) It is advantageous to make the plate, flange, face plate and side panels from robust materials such as metal that can withstand the effects of weather. The plate and flange may be, for example, aluminum or stainless steel to prevent corrosion, and the faceplate and side panels may be copper or brass for a decorative effect. Plastics and fiber reinforced composites may also be used, as well as a combination of metals, plastics and other materials.

(16) As shown in FIG. 5, the lamp 10 is integrated into a hardscape structure, such as a retaining wall 38, a portion of which is shown in phantom line. Retaining wall 38 is formed from discrete block-like elements 40 positioned atop one another, and the plate 12 of lamp 10 is positionable between the block-like elements 40 for mounting on the wall. The plate is thin enough and the blocks sufficiently coarse that the presence of the plate does not significantly affect the stacking of the blocks. The lamp takes the orientation of the strata in which it is positioned. The lamp is retained to the wall by contact between the plate 12 and the block-like elements 40 and does not require separate fasteners. The lamp is positioned with a portion of the plate 12 projecting from the wall so that the flange 14 is in spaced relation away from the wall. This provides a space between the flange and the wall for the light fixture and the bulb to illuminate the surrounding area.

(17) FIG. 6 shows an illuminated hardscape 42 being constructed, in this example, the aforementioned retaining wall 38. A plurality of lamps 10 are integrally mounted within the retaining wall by positioning the plates 12 between discrete block-like elements 40 as they are stacked atop one another to form the hardscape. No special tools are required, and the components of the lamp are readily accessible for repair or replacement, providing significant ease of maintenance. Power lines 28 extend from the lamps and are connected via a bus 44 to a power source, such as a transformer 46, which steps 110 volt household electrical service to a low voltage typically used with outdoor lighting systems. Although plates 12 are shown oriented horizontally in the wall 38, it is understood that a vertical orientation is also feasible by positioning the plate within the vertical seam between two adjacent block-like elements 40.

(18) FIG. 7 shows another embodiment of a lamp 48 according to the invention. Lamp 48 is configured asymmetrically so that it casts its light 50 predominantly to one side. Lamp 48 is constructed similarly to the embodiments previously described in that it comprises a plate 52 and a flange 54. The flange is asymmetrically arranged with an elongated side panel 56 on one side which helps to direct the light in a preferred direction. The lamp may also include a face plate 58 to hide the structural components of the lamp and further direct the light as desired. Note that the elongated side panel may be integrally formed with the flange, attached to the flange, integrally formed with the face plate, or attached to the face plate. As shown in FIG. 8, a light fixture 60 is attached to lamp 48, preferably to flange 54. The light fixture receives a bulb 62 and has a power cord 64.

(19) Asymmetrical lamps 48 are advantageous for illuminating treads 66 of steps 68 as shown in FIG. 9. Two lamps may be positioned in spaced relation along a riser 70 and oriented so that their light 50 converges on the tread 66. This configuration will provide more even illumination of steps and better define the limits and extent of the steps for both safety and aesthetic advantage.

(20) With reference to FIG. 10, an embodiment providing a light transmitting cover attached to the lamp 10 to cover light fixture 18 (including the socket 20 and bulb 22) is now described. In this preferred embodiment, a decorative face plate 30a, similar to the faceplate 30 shown in FIGS. 1 and 2, is attachable to the plate 16 overlying the surface 14a of the flange 14 in a similar manner as that of faceplate 30, which in this case would be attached with screws 32. A rectangular light transmitting cover 72 extends along a bottom of the face plate 30a between side panels 34 supported on support tabs 74 which extend from the side panels 34 as illustrated. The light transmitting cover can be made of any suitable material, such as polycarbonate or borosilicate glass, and preferably attached to the face plate with a suitable adhesive 76 such as a silicone RTV (room temperature vulcanizing) sealant. As used herein, light transmitting includes any suitable light translucent and light transparent materials, as well as lenses or other materials that allow light to pass through.

(21) The light cover 72 prevents water from splashing onto the bulb and socket. When the light is on, the bulb and socket can get very hot and become prone to cracking if splashed with much cooler water, e.g., rain that splashes off of the pavement and up into the light fixture. The light cover also offers other benefits, such as the ability to enhance the light through the use of filters, colored glass to color the light, lenses to diffuse or focus the light, and to provide other desirable effects. It is also appreciated that other embodiments are possible. For example, the light cover could be in the form of a smaller cover or of different shapes and can be mounted to the lamp in different ways. Other possible alternative embodiments contemplated include a cover that clips onto the bulb or socket, or which is attached directly to the plate 12 and not through the decorative face plate 30a. It is also appreciated that by adding the light cover to the face plate 30a or other attachable means which can be added easily to the lamp, various alternative options for different light enhancements can be provided to the consumer.

(22) Lamps according to the invention 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.
