  • Patent number: 10571116
    Abstract: The invention relates to a ceramic tile (1) with a glaze (11) which covers at least the visible face (10). A light generated by one or more light sources (6, 14) is visible on the visible face (10), and at least one bore (2) and/or recess (22) passes through the body of the ceramic tile (1). The glaze (11) is designed to guide light and at least partly fills the bore (2) and/or the recess (22) in a sealing manner, and the one or more light sources (6, 14) are arranged on the rear face of the ceramic tile (1) and are connected to the bore (2) and/or the recess (22) so as to guide light.

  • Patent number: 8997415
    Abstract: A light-conducting component, in particular finished concrete part in the form of a masonry brick, for constructions and buildings. The component is produced in a casting mold by casting into at least one casting building material and the optical waveguide is made of a light-conducting building material, e.g. PMMA polymer or glass, which is accessible at at least two positions on the outer surface of the light-conducting component for the input of light and output of light. The optical waveguide is configured as a self-supporting 2D or 3D lattice body composed of rods having a thickness/diameter of greater than 1 mm. The self-supporting 2D or 3D lattice body has approximately the same or an only slightly smaller width (W), or length (L), or base dimensions (W, L), or total external dimensions (W, L, H) than the casting mold itself.
