Abstract

A radiation-emitting semiconductor chip includes a semiconductor layer sequence having an active layer for generating electromagnetic radiation. The semiconductor chip also includes a reflector at a side surface of the semiconductor layer sequence having a reflector surface facing the semiconductor layer sequence and extending obliquely with respect to the active layer. The semiconductor chip further includes a top surface extending transversely with respect to the reflector surface and having a first emission region. The semiconductor chip additionally includes a further reflector situated opposite the reflector. The semiconductor chip is configured such that electromagnetic radiation generated in the active layer during operation is reflected by the reflector and emerges from the semiconductor chip via the emission region of the top surface. A main emission direction of the emerging electromagnetic radiation together with the active layer form an emergence angle of between 30° and 80° inclusive.
