COLOR CORRECTING COLLIMATION OF LIGHT FROM A COLOR OVER POSITION LIGHT SOURCE

WIPO Patent Application WO/2016/124449

A8

A collimator (3) for a color over position light source (2) is provided. The collimator (3) comprises a focal point (F), an optical axis (OA) containing the focal point (F), an imaging element (4) arranged around or on the optical axis (OA) and several light spreading elements (5, 11, 12) arranged around the optical axis (OA) to receive at least one image from the imaging element (4). The light spreading elements (5, 11, 12) have different light beam widening characteristics, the light beam widening characteristics of each light spreading element (5, 11, 12) of said light spreading elements (5, 11, 12) depending on the position of the light spreading element (5, 11, 12) relative to the focal point (F). The light spreading elements (5, 11, 12) are adapted to spread light striking the light spreading elements (5, 11,12) in a first plane (M) including the optical axis (OA). A method for collimating light from a color over position light source (2) is also provided.
