Abstract
The deflector has planar light inlet and outlet surfaces, with boundary layers which refract and/or reflect the light disposed between the planar surfaces. The inlet and outlet surfaces are surfaces of two respective flat elements (e.g. E1) which each have a protruding surface structure (2) on the side opposite to the light entry surface. The surface structures of the two elements are formed such that when the elements are combined the surface structures interengage so that gaps are formed defined by the walls (3,3',4,5) of the surface structures of two elements. Preferably the elements are made of material which is transparent to sunlight e.g. acrylic. USE - For providing dazzle-free internal illumination throughout a room. ADVANTAGE - Provides light with almost loss free reflection while not adversely affect see-through properties so that a user can see other side of object without distortion or colour errors, and is manufactured in a simple low-cost manner.
