ABSTRACT:
A light module includes a light source and a reflective light transformer. The light source emits light with a limited angle omnidirectionally in a plane perpendicular to a light source optical axis. The reflective light transformer is located around the light source, and collects most of the light emitted by the light source and redirects and redistributes the collected light in a direction parallel to the light source optical axis. The light transformer includes a reflective surface with a precalculated arbitrary profile that transforms a light source spatial light distribution into a specific pattern with a generally different angular spread in a horizontal plane and a vertical plane.
