Abstract

A luminescence diode arrangement includes a first luminescence diode chip, a second luminescence diode chip and a luminescence conversion element, wherein the first luminescence diode chip emits blue light, the second luminescence diode chip contains a semiconductor layer sequence that emits greens light, the luminescence conversion element converts part of the blue light emitted by the first luminescence diode chip into red light, and the luminescence diode arrangement emits mixed light containing blue light of the first luminescence diode chip, green light of the second luminescence diode chip and red light of the luminescence conversion element.
