Active luminescent paving stone for use on e.g. roof region, has solar cells that are provided with retaining points, where retaining blocks are symmetrically constructed so that each block holds solar cell at each side of block

摘要

The stone has an active luminescent concrete unit comprising an illuminant that is supplied with energy by an energy supply unit, and an energy storage charged using solar cells and electronics. Sensors in the concrete unit switch on and off the illuminant using the electronics. The solar cells are provided with retaining points, where retaining blocks (2) are symmetrically constructed so that each block holds the solar cell at each side of the block. An underlay plate (4) is formed underneath a screw (1), and distributes force of the screw on the retaining blocks. An independent claim is also included for an active luminescent concrete unit comprising an illuminant.
