Abstract
A semiconductor light source comprising first and second light-emitting diode chips; and a conversion element containing a first phosphor and a second phosphor, wherein the conversion element is disposed downstream of the first and second light-emitting diode chips. The first light-emitting diode chip emits electromagnetic radiation with a first emission maximum. The second light-emitting diode chip emits electromagnetic radiation with a second emission maximum. The first phosphor has a first absorption maximum and a first radiating maximum. The second phosphor has a second absorption maximum, which differs from the first absorption maximum, and a second radiating maximum, which differs from the first radiating maximum. The degree of conversion of the first phosphor for the electromagnetic radiation of the first light-emitting diode chip is greater than the degree of conversion of the second phosphor for the electromagnetic radiation of the first light-emitting diode chip.
