Abstract
A light-emitting diode device has a first carrier and at least one light-emitting diode chip, which is arranged on the first carrier. The first carrier has at least one first and one second carrier part, wherein the light-emitting diode chip rests only on the first carrier part. Furthermore, the first and second carrier parts each have a thermal conductivity. The thermal conductivity of the first carrier part is at least 1.5 times the thermal conductivity of the second carrier part. The first carrier part is surrounded laterally by the second carrier part.
