Abstract

A light assembly disperses light emitted by a light source. The lighting assembly includes a light entry surface for receiving the light emitted by the light source. A direction surface directs the light in a predetermined direction. A stepped region, disposed adjacent the light entry surface receives the light directed by the direction surface and reflects the light. The stepped region includes a plurality of step parts, each defining a light deflection surface, wherein each of the light deflection surfaces is greater in area s step distance between the light deflection surface and the direction surface increases.
