Aluminium anti dazzle lampshade - has mesh of strips with both sides stepped and forming concave reflective surface

摘要

The lamp shade forming an anti dazzle screen, is made of a network of strips, as in the main patent. Each strip is made of aluminium sheet, which is rolled so that it has a stepped shape on both sides. Each step has a concave reflective surface so that the reflected light is directed towards a common focal point, followed by a shorter abrupt portion. The junction between these two is rounded. The other side is similarly shaped, but the steps on one side are staggered with respect to those on the other side.
