Said system also comprises a transparent protective body (3), which when mounted covers the light-emitting body (2) on the surface (6) side and lies flush with said surface (6). ## Claims ### Claim 1 An illumination system for a wall, a ceiling or a floor, comprising at least one point-type light-emitting body, which is connected to a light source by means of an optical fiber and which when mounted is recessed in relation to a surface of the wall, the ceiling or the floor, a light-transmitting protective body which when mounted covers the light-emitting body towards the surface and is positioned so as to be recessed in relation to the surface, and a facetted diamond-shaped body connected to the protective body by way of a sleeve, positioned in the wall, in the ceiling or in the floor, on a side facing away from the surface of the protective body, wherein the diamond-shaped body is connected to the light-emitting body in order to input light, the diamond-shaped body comprising a body which is facetted in order to achieve light refraction, and wherein the body of the diamond-shaped body is made of at least one of crystal, glass and precious-stone, and wherein the sleeve comprises a light-impervious bottom through which the light-emitting body is connected to the diamond-shaped body, and wherein the wall, the ceiling or the floor is designed as a mosaic in the region of the protective body, with said mosaic comprising a multitude of individual mosaic elements, the mosaic comprising at least one installation unit that has a carrier plate on which at least part of the mosaic is pre-assembled and on which the associated light-emitting body is attached. ### Claim 2 (depends on 1) The illumination system according to claim 1, wherein the protective body is designed so as to be at least one of water-resistant, able to be walked on, and scratch-resistant, and when mounted is installed in the wall, the ceiling or the floor so as to be at least one of water-resistant, able to be walked on, and so as to be scratch-resistant. ### Claim 3 (depends on 1) The illumination system according to claim 1, wherein the protective body comprises glass, security glass, highly-resistant glass or synthetic glass. ### Claim 4 (depends on 1) The illumination system according to claim 1, wherein the diamond-shaped body is arranged so as to be spaced apart from the protective body. ### Claim 5 (depends on 1) The illumination system according to claim 1, wherein apart from its light-emitting side that faces the protective body, the diamond-shaped body, is metal-coated on the inside, at least over part of its surface. ### Claim 6 (depends on 1) The illumination system according to claim 1, wherein at least one of the protective body and the diamond-shaped body are affixed to the sleeve by means of a light-resistant, light-transmitting adhesive that cures without blister formation. ### Claim 7 (depends on 1) The illumination system according to claim 1 wherein the diamond-shaped body is enclosed by the light-impervious sleeve. ### Claim 8 (depends on 7) The illumination system according to claim 7, wherein the sleeve furthermore encloses the protective body. ### Claim 9 (depends on 1) The illumination system according to claim 1, wherein the protective body, the diamond-shaped body and the light-emitting body form a unit that can be pre-assembled. ### Claim 10 (depends on 1) The illumination system according to claim 1, wherein the light-emitting body comprises a deviation section which deflects the light fed in and/or the optical fiber by approximately 90°. ### Claim 11 (depends on 1) The illumination system according to claim 1, wherein in a top view of the surface, the protective body has essentially the same dimensions as the mosaic elements.
