Abstract

A device with semiconductor chips on a primary carrier is disclosed. In an embodiment a device includes a primary carrier, a plurality of semiconductor chips arranged on the primary carrier, a radiation conversion material arranged at least in places on the semiconductor chips and the primary carrier, a secondary carrier to which the primary carrier is attached and a scattering body arranged on a front side of the secondary carrier facing the primary carrier, the scattering body covering the semiconductor chips, wherein the primary carrier is formed reflective to primary radiation at least in a region of the semiconductor chips, and wherein, during operation of the device, at least secondary radiation exits through a front side of the scattering body facing away from the secondary carrier and through a rear side of the secondary carrier facing away from the primary carrier.
