Light-emitting construction element

1. A non-transparent light-emitting construction element comprising:

a construction element having a mounting side and a user-facing side to be facing a user when said light-emitting construction element is used in a construction; and

a light-emitter embedded in said construction element,

wherein said light-emitter is embedded in said construction element in such a way that said light-emitter is non-visible in its off-state and light from the light-emitter escapes from the construction element when the light-emitter is in its on-state,

wherein said construction element comprises:

a top layer having a user facing side and a mounting side, wherein said mounting side comprises a plurality of cavities; and

a carrier comprising a plurality of light-emitters, each being arranged in a respective one of said cavities in said top layer,

wherein said top layer has a rough surface having peaks and valleys and wherein said cavities in said top layer are extending through said top layer and wherein the light-emitters are protruding from the surface of said top layer.

2. The light-emitting construction element according to claim 1 , wherein said construction element material is selected form the group comprising stone, ceramics, concrete, porphyry and marble.

3. The light-emitting construction element according to claim 2 , wherein said light-emitter is the light-output region of a light-guide.

4. A method for manufacturing a non-transparent light-emitting construction element comprising the steps of:

providing a carrier having at a plurality of light-emitters arranged thereon;

providing a layer of construction element material arranged on said carrier such that said at least one light-emitter is embedded in said construction element material in such a way that said light-emitter is non-visible in its off-state and light from the light-emitter escapes from the construction element when the light-emitter is in its on-state,

wherein a layer of construction element material has a user facing side and a mounting side,

wherein said mounting side comprises a plurality of cavities and wherein each of the plurality of light-emitters is arranged in a respective one of said cavities in said layer of construction element material, and wherein said layer of construction element material has a rough surface having peaks and valleys and wherein said cavities in said layer of construction element material are extending through said layer of construction element material and wherein light-emitters are protruding from the surface of said layer of construction element material.

5. The method for manufacturing a non-transparent light-emitting construction element according to claim 4 , further comprising the step of arranging said carrier and layer of construction element material on a support layer.

6. The light emitting construction element according to claim 1 , wherein the color and texture of the portion of the light-emitter protruding from the surface is adapted to match the appearance of the surface.

7. The light emitting construction element according to claim 1 , wherein the peaks of the rough surface extend above the protruding light-emitter.

8. The light emitting construction element according to claim 1 , wherein the cavities are larger than the light emitters.

9. The light emitting construction element according to claim 2 , wherein space around the light emitters and between the carrier and the top layer is filled with silicone or epoxy.

10. The light emitting construction element according to claim 1 , wherein the carrier is provided in the form of a net.
