Abstract
A light-emitting diode module for emitting white light includes a first light emitting diode chip for generating radiation in the blue spectral range having a first peak wavelength, a second light emitting diode chip for generating radiation in the blue spectral range having a second peak wavelength, a third light emitting diode chip for generating radiation in the red spectral range having a third peak wavelength, a first and a second phosphors disposed downstream of the first and the second light emitting diode chips, respectively. The first light emitting diode chip with the first phosphor generates a first mixed radiation and the second light emitting diode chip with the second phosphor generates a second mixed radiation. The first phosphor exhibits a first absorption maximum at a wavelength greater than the first peak wavelength. The second phosphor exhibits a second absorption maximum at a wavelength less than the second peak wavelength.
