Abstract
An optical attachment for a light source, in particular for a light-emitting diode exhibits an inner lens area which surrounds an optical axis of the optical attachment for inner light beams emitted from the light source and an outer reflector area for outer light beams of the light source which surrounds the inner lens area in a ring-like manner. Due to this combination of refraction in the inner lens area and reflection in the outer reflector area, the dimensions of the optical attachment can be kept relatively small and, in comparison to a lens or a reflector, more light can be collected and the point-shaped light diode can be imaged on the exiting side as a large area light appearance.
