ABSTRACT:
A device for shielding outside lights comprising an essentially cylindrical, transparent shield body with a surface which is provided with a zigzag-shaped profile in a vertical direction in order to deflect the radiation from a lighting source incident on the shield body in a desired direction. Triangular projections of the zigzag-shaped profile in a first portion are designed and configured in such a way that the radiation from the lighting source is fully reflected in a desired direction when passing through the first portion of the shield body and triangular projections of the zigzag-shaped profile in a second portion are designed and configured in such a way that the radiation from the lighting source is diffracted in the desired direction when passing through the second portion of the shield body.
