A light source assembly ( 212 ) for providing a homogenized light beam ( 224 ) includes a first light source ( 234 ), a second light source ( 236 ), and an optical pipe ( 228 ) that defines a pipe passageway ( 228 A). The first light source ( 234 ) generates a first light ( 234 A) that is directed into the pipe passageway ( 228 A) at a first region ( 228 I). The second light source ( 236 ) generates a second light ( 236 A) that is directed into the pipe passageway ( 228 A) at a second region ( 228 H) that is different than the first region ( 228 I). The optical pipe ( 228 ) homogenizing the first light ( 234 A) and the second light ( 236 A). Additionally, the light source assembly ( 212 ) can include a third light source ( 238 ) that generates a third light ( 238 A) that is directed into the optical pipe ( 228 ) at a third region ( 228 G) that is different than the first region ( 228 I) and the second region ( 228 H).
