Abstract
An optical arrangement, comprises first and second optical elements. The first optical plate is for collimating light from a light source to generate collimated light, which is provided to the second optical element. The second optical element acts an optical integrator homogenizing the light. The second optical element further generates a light output beam which has a spread of output angles which is dependent on the position. This means that the output spread of output angles can be controlled by controlling the light reaching the second optical plate and thus by controlling the illuminated area on the second optical plate. This can be achieved by selection of the relative positions of the source and the optical plates.
