LIGHT SHAPING OPTICAL ELEMENT

摘要

The present invention relates to a light emitting arrangement (20) comprising a light source (22) and a scattering member (24). The scattering member (24) is arranged in a three dimensional shape in front of the light source (22) in a light output direction. Different regions of the scattering member have different optical characteristics to provide a desired total light output in respect of brightness level scattering function and beam shape.
