Abstract

A light-emitting arrangement includes a radiation-emitting semiconductor chip that, during operation, emits primary radiation at least from a main emission surface, a first conversion element that absorbs part of the primary radiation and emits secondary radiation, and a deflection element that causes a direction change for part of the primary radiation, wherein the first conversion element is arranged in a lateral direction next to the radiation-emitting semiconductor chip, the deflection element guides part of the primary radiation onto the first conversion element, and the light-emitting arrangement, in operation, emits mixed light including the primary radiation and the secondary radiation.
