An illumination system includes a lightguide having light extractors. A first light source is disposed at an end face of the lightguide. Light emitted by the first light source is extracted from the lightguide by the light extractors and exits the lightguide primarily along a first direction different than the length direction. A second light source is disposed along the length of the lightguide. Light emitted by the second light source enters the lightguide from a first side surface and exits the lightguide from a different second side surface along a second direction different than the first and length directions. Light emitted by the second light source has a first divergence in a first plane before entering the lightguide through the first side surface and a different second divergence in the first plane after exiting the lightguide from the second side surface.
