Abstract

The invention provides a light generating device () comprising (i) a plurality of n light sources (), and (ii) an optical component () comprising an array () of prismatic elements (), wherein: (a) the plurality of n light sources () comprise a first subset of one or more first light sources () configured to generate collimated first light source light () and a second subset of one or more second light sources () configured to generate collimated second light source light (), wherein n>2; (b) the array () of prismatic elements () is configured in a light receiving relationship with the n light sources (), wherein the array of prismatic elements () comprises k1 parallel arranged first prismatic faces () and k2 parallel arranged second prismatic faces (), wherein k1>2 and wherein k2>2, wherein the first prismatic faces () and the second prismatic faces () are not mutually parallel; (c) the first light sources () are configured to irradiate the first prismatic faces () and the second light sources () are configured to irradiate the second prismatic faces (); and (d) the prismatic elements () are configured to reflect or refract the collimated first light source light () and the collimated second light source light () as coincident beams of first light source light () and second light source light ().
