摘要
The invention provides an optical beam shaping arrangement for example for use as part of a spot light. A collimator is for receiving light from an optical source, and providing a more collimated output. An optical plate is provided at the output of the collimator and comprises an array of lenses on an input side and a corresponding array of lenses on the opposite output side. The lenses are arranged as Koehler lens pairs, and wherein at least some of the lenses on the output side are tilted with respect to the general plane of the optical plate. This tilting provides a design option for improving the beam shaping properties.
