Definitions

  • One of the main costs of the mirrors has its origin from forming a glass sheet (glass plate) with a precise parabolic shape.
  • the bending of the glass sheet is usually done in a hot furnace using a high temperature.
  • the present invention provides method for manufacturing a bended glass sheet with a permanent glass sheet bending, wherein the method comprises the following steps: a) Providing a tempered flat precursor glass sheet with a glass sheet thickness selected from the range between 2 mm and 10 mm; b) bending the tempered flat precursor glass sheet with the aid of an external bending force such, that a bended glass sheet with a glass sheet bending results; and c) fixing the glass sheet bending of the bended glass sheet such, that the permanent glass sheet bending results; wherein the bending the tempered flat precursor glass sheet is executed at a bending temperature which is selected from the range between 0°C and 70 °C. In a preferred embodiment the bending temperature is selected from the range between 0°C and 50 °C and particularly from the range between 0°C and 40°C.
  • the method is used for manufacturing a bended mirror with a permanent mirror bending.
  • the tempered glass sheet is coated with a multilayer stack with a reflecting layer containing Silver.
  • the reflecting layer contains Aluminium or other suitable materials. This coated glass sheet is brought into the desired parabolic shape by the described bending process.
  • one "long" mirror can be used. This reduces the costs and improves the optical performance of the concentrator of sunlight.
  • a manufacturing system for executing the method with at least one fixing device for the fixing the glass bending is provided .
  • the external force is caused by at least one power source selected from the group consisting of vacuum, air pressure, mechanical moment force, gravitation and distributed pressure force.
  • the tempered flat precursor glass sheet is fixed at edges of the precursor glass sheet. Point pressure at the edges of the flat glass plate is carried out. Due to the flexibility of the tempered flat precursor glass sheet a center of the tempered flat precursor glass sheet can be moved. The bending of the precursor glass sheet is carried out. Alternatively the center of the flat precursor glass sheet is fixed and the edges of the precursor glass sheet are moved.
  • a holder comprising at least one holder frame, wherein the bending the flat precursor glass sheet and/or the fixing the glass sheet bending of the bended glass sheet are carried out with the aid of the holder frame. For instance, by the holder frame the glass sheet is just held on its edges.
  • a bended glass sheet 121 with a glass sheet bending 122 results.
  • the next step is the fixing the glass sheet bending of the bended glass sheet.
  • the permanent glass sheet bending results.
  • a bended mirror with a permanent parabolic mirror bending is obtained.
  • a holder 14 is used for the bending of the mirror.
  • the mirror assembly with the bended mirror and with the holder results (figure 2) .
  • the holder has the function of the mirror bending fixing device.
  • the bended mirror and the mirror assembly with the bended mirror respectively are used in a solar field for the concentrating sunlight .
