(35) Identical reference numbers subsequently designate similarly designed components or component areas.

(36) The installation set 1 can be advantageously used to make a lighted niche, even in wet areas such as shower and bath installations. The system can include a niche 3 formed from one or more hard foam 2 panels which collectively define an installation element 4. A rectangular rear wall 5 can be abutted by four projecting side walls 6, 7, 8 and 9. A projecting frame 10 can be attached to or extend outwardly from the side walls 6, 7, 8, 9. The hard foam panels can be formed such that both sides include a stiffening layer (not shown) and an outer fleece coating 11. The stiffening layer can include a plastic layer onto which the nonwoven fabric coating 11 can be applied during production while in the not yet fully cured state. In one non-limiting example, the rear wall, side walls and projecting frame can each be formed from a material commercially available as Kerdi-Board, and each can be sealed in a water-tight fashion to the others.

(37) The lower side wall 6 shown in FIG. 1 can be provided with a through hole 12 (see FIG. 4, for example). The through-hole can serve to allow a water-tight connection to be made within the niche to one or more components located outside of the niche. An insert part 13 can be inserted within the through-hole to define a receiving space 14 therein. The insert part 13 can be made of plastic and can include a support flange 15 that at least partially surrounds the insert part, so that it cannot slip through the through hole 12 and through the lower side wall 6.

(38) In the area of the receiving space 14, an opening or breakthrough 16 for passing a power cable 17 can be formed. A cover 18 can be provided to cover the receiving space 14 at the level of the side wall 6 is largely closed. The cover 18 can include a plurality of cover segments 19 which are each U-shaped, with the downwardly projecting legs of the respective cover segments 19 being inserted from above into the receiving space 14. The downwardly projecting legs serve as clamping legs and engage the walls of the receiving space 14 to cooperatively and mechanically fix the cover segments 19 within the receiving space. Once properly installed within the through-hole, the cover can form a relatively flat plane in relation to the flat surface of the lower side wall 6. Thus, tiles or other materials can be flatly installed over the insert and the surface of the side wall. The upper side of each cover segment 19 can be provided with a fleece coating 20. A power cable 17 can be provided at the end with connection elements 21, 22. The attachment of the power cable 17 to the insert via a conventional cable gland 23 (FIG. 9, for example), which may be waterproof. In this manner, a water-tight connection is made between the cable 17, external to the niche.

(39) The installation kit 1 can also include a waterproof LED light strip 24 (see FIG. 15 et. al). The light strip can have a length that corresponds to a length of an inside surface of the mounting element 4. The passage opening 12 on the side wall 6 of the mounting element 4 can provide a manner by which an electrical connection can be formed with the LED strip and a component external to the niche. The LED strip can include a connection element 25 connecting cable 26. In one example, the LED light strip can include a board provided with LEDs, which can be encapsulated, for example, with a water-tight, translucent, silicone-like plastic. The installation set 1 can include an extruded profile 27, the length of which corresponds to the length of the LED luminous strip 24. The extruded profile 27, which can be made of aluminum or stainless steel, can include a U-shaped section 28 (viewed in cross-section). The base can include a base web 29 (see FIG. 21, for example) and two end sides or webs 30 that form a positive reception location for the LED light strip 24.

(40) The base web 29 can be provided with two elongated holes 31 (see FIG. 19, for example), the positions of which can correspond to the position of the connection cable 26 of the LED light strip 24. In this manner, the LED light strip 24 can be in two locations, offset by 180° from one another, connected through the U-shaped section 28. Furthermore, the extruded profile 27 can include a fastening web 33 provided with through holes 32. The fastening web can adjoin the base web 29 flushly and can project outwardly from the U-shaped section 28. The positions of the connection cable 26 and the receiving space 14 of the insertion part 13 can be matched to one another in such a way that the connecting cable 26 projects above the receiving space 14 when the LED light strip 24 is mounted on the side wall 6 of the installation element 4 provided with the passage opening 12. In one example, the dimensions of the receiving space 14 are selected such that the power cable 17 can be connected to the connecting cable 26 via their connection elements 21, 25 with the connection elements stored or accommodated therein.

(41) For mounting the installation kit 1, starting from the arrangement shown in FIG. 25, the cover 18 can be lifted off the insertion part 13, resulting in the arrangement shown in FIG. 14. The connecting cable 26 can extend from the extruded profile 27 LED light through one of the holes 31 and can be connected to the power cable 17. To accomplish this, the respective connection elements 21, 25 of the power cable 17 and the connecting cable 26 are formed correspondingly and advantageously for forming a watertight connection. Once the extruded profile 27 is positioned and fastened with the LED light strip 24 received therein, it can be positioned in various positions on the lower side wall 6 of the installation kit 1. Examples of these differing positions are shown in FIGS. 30 to 32. Varying the orientation of the profile can result in a differing lighting effect within the niche.

(42) The position or connection of the individual cover segments 19 of the cover 18 can be varied in accordance with the positioning of the LED light strip 24 in the extrusion profile 27 to ensure that the cover 18 immediately below the connection cable 26 of the LED Luminous strip 24 leaves an access to the receiving space 14. Thus, for example, while only two cover segments may not completely cover the receiving space, the remaining space can be consumed by the extruded profile. This remaining space can allow the extruded profile to be positioned in a number of locations over the opening while still providing an access port for the connection cable.

(43) Attachment of the extruded profile 27 on the lower side wall 6 of the mounting element 4 can be carried out during the tiling of the mounting element 4 with tiles or the like in the thin-bed process or with appropriate spatula-paving materials. For this purpose, both the corresponding surfaces of the installation element and the cover can be provided with nonwoven fabric coatings, in which thin-bed mortar or similar covering materials can be anchored.

(44) FIGS. 33 and 34 illustrate a further example of the technology in which insert or insertion part 13a is provided having a relatively pliable body material, such as silicone. In this embodiment, the support flange 15a can be formed at least partially of a fabric material, similar to the material commercially available as Kerdi. This example can advantageously be used in place of the insert 13 discussed above, or can be used in planar sections of shower walls, niche walls, etc. Opening or through hole 12a can be formed in a wall section, for example, with power cable 17 and terminal connector 21 accessible therethrough. As shown in the progression of FIG. 33, the power cable can be fed through opening 16a formed in the pliable wall. The opening can define a pliable shroud: once the power cable is positioned where desired, a securing tie 34, such as a cable tie, can be cinched about the shroud around the power cable. In this manner, a waterproof fitting can be ensured about the cable.

(45) FIG. 34 illustrates one exemplary process by which the wall box 13a can be inserted within opening or through hole 12a formed in a planar wall surface. Once positioned where desired, cover elements 19a can be secured across the cavity defined by the wall box. In the example shown, the cover elements 19a include pliable strips that can be formed from or include the fabric material referenced above. These strips can include a “peel-and-stick” adhesive applied to rear surfaces thereof, which can be adhered over the wall box as shown in the rightmost figure of FIG. 34. Once so positioned, an LED light strip can be positioned and installed atop the wall box. A connecting cable of the light strip can be connected with the power cable 17, and the connectors can be stored beneath the cover strips. Only a very small opening will remain, which can prevent most of the thinset mortar used to fix the LED light strip and any adjacent tiles over the wall box.

(46) In addition to using peel-and-stick adhesive on rear surfaces 19a of the cover strips, the strips can be secured in position using the thinset mortar used in the remaining installation.

(47) The wall box 13a can advantageously be installed in open, planar areas of a wall surface, and very near corners or edges of wall or niche surfaces. As the fabric support flange 15a is flexible and reconfigurable, the body of the wall box can be installed in a through hole immediately adjacent to a corner or edge of a panel, and the support flange can be wrapped or folded into or around any adjoining structure. As the body is formed from a waterproof silicone or the like, a watertight installation can be achieved in a variety of locations chosen during the installation.
