Structures for light activation are normally implemented on the surface of the light guides. Weidplas, from Switzerland, has researched and developed a technology to implement the light scattering structures with lasers into the volume of the light guides. With this technology the structures are protected in the volume against outer impacts and you can create three dimensional effects with illuminated objects by lasering the structures in different depths of the light guide.
Combined with nearly invisible microstructures, lasered in the volume of light guides, you can realize amazing lighting applications, which “hidden until lit” effects.
Figures 5 and 6 show a window and a panoramic roof, which are transparent in the “light off “mode. In the “light on” mode, you suddenly see illuminated 2d- or 3D structures and light patterns, which are lasered on demand of the stylists.
