Abstract

A lighting module includes an optoelectronic semiconductor chip and a converter element for wavelength conversion. The optoelectronic semiconductor chip emits electromagnetic radiation including a dominant wavelength of 430 nm to 450 nm. The converter element includes a first phosphor and a second phosphor. The first phosphor is a garnet phosphor. The first phosphor emits electromagnetic radiation including a wavelength from the blue-green spectral range. The second phosphor is a nitrido-silicate phosphor. The second phosphor emits electromagnetic radiation including a wavelength from the orange-red spectral range.
