Abstract
A lighting module may include a light source; a lens arranged at a distance from the light source; and a reflector; wherein the lens is configured and arranged to have a wide-angle emission characteristic and to direct a proportion of the light incident from the light source onto the reflector, wherein the proportion is at least 30%.
Claims20
A lighting module, comprising at least:
- at least one light source;
- a respective lens arranged at a distance from the light source;
- and
- a reflector which surrounds the at least one light source completely about the optical axis;
- wherein the lens is configured and arranged to have a wide-angle emission characteristic and to direct only a portion of the light incident from the light source onto the reflector, wherein the portion is at least 30%.
