Abstract: A lighting device is provided that includes a light source and an optical element. The light source emits primary light having a primary emission characteristic. The optical element has a light entry face and a light exit face. The optical element includes light guiding elements each forming part of the light entry and exit faces. The light entry faces inject the primary light into the optical element. The light guiding elements each have a boundary surface that totally internally reflects the primary light so that the light exit face emits a secondary light. The optical element reduces a divergence of the primary light such that the secondary light has a secondary emission characteristic with an emission angle (?) that is smaller than an emission angle (?) of the primary emission characteristic. The light exit face is larger than the light entry face.

Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information on the origin and/or tube-specific production data of the glass tube semi-finished product, which marking is read from the hollow glass product after its manufacture to determine the origin and/or the tube-specific production data of the glass tube semi-finished product, e.g., to identify the semi-finished glass tube from which the hollow glass product has been made, and/or trace the tube-specific production data of this glass tube semi-finished product. This means that the entire supply chain for the hollow glass product from the supplier of the originally used glass tube semi-finished product up to the end product can be determined. The physical and chemical characteristics of the glass tube semi-finished product are not altered for producing the first marking.

Abstract: A glass composite is provided that has a first and second glass element, each having a first surface, and a first coupling agent layer having a first and second silane coupling agent. The first coupling agent layer has covalent bonds between the first and second silane coupling agents. The first and second silane coupling agents are covalently bonded to the first surface of the first and second glass elements, respectively. The first and second glass elements are irreversibly connected by the first coupling agent layer. Such a glass composite is made by bonding the first surface of the first and second glass elements to the first and second silane coupling agents, respectively, and contacting both first surfaces with each other to cause the first and second silane coupling agents thereon to covalently bond so that the first and second glass elements are irreversibly connected.
