A light source, includes a component (6) for emitting light, arranged to emit a major part of light generated within the component through a face (8) of the component (6), and at least one structure (7;18) for coupling out light, having a base (11;19) in contact with the face (8) of the component (6) and arranged to emit light through an aperture (12;20) opposite the base (11;19). An interface between the component (6) and an environment surrounding the base (7;18) is arranged to keep at least part of the light generated in the component confined to at least a layer of the component (6) adjoining the base (11;19). The base (11; 19) is in contact with the face (8) over an area (A2) smaller than the area (A0) of the face (8).
