Abstract
A light-emitting assembly includes a first light guide element and a second light guide element, which have end sections connected to each other, the end sections having a main light propagation direction. The first and second light guide elements further having light guide sections which spread out from the top of a connection region of the end sections. A middle element is located between the light guide sections of the light guide elements and spaced apart from the top, the middle element having a light entry face and a light exit face which is opposite the light entry face and configured to emit light between the spread-out light guide sections. At least one of the light entry face and the light exit face has a light-transmitting region with a predetermined shape, the light-transmitting region occupying a part of a corresponding face of the middle element.
