Claim Text:
1. A phosphor converted Light Emitting Diode comprising: a Light Emitting Diode emitting a first spectral distribution having a first peak wavelength in the blue spectral range between 445 nanometers and 495 nanometers, a first luminescent material configured for absorbing a portion of the light of the first spectral distribution and for converting at least a portion of the absorbed light into light of a second spectral distribution, the second spectral distribution having a second peak wavelength in the green spectral range, a second luminescent material configured for absorbing a portion of the light of the first spectral distribution and/or a portion of the second spectral distribution and for converting at least a portion of the absorbed light into light of a third spectral distribution, the third spectral distribution having a third spectral width and having a third peak wavelength, a third luminescent material configured for absorbing a portion of the light of at least one of the first spectral distribution, second spectral distribution, and the third spectral distribution and for converting at least a portion of the absorbed light into light of a fourth spectral distribution, the fourth spectral distribution having a fourth spectral width and having a fourth peak wavelength, wherein the third peak wavelength and the fourth peak wavelength are in the orange/red spectral range, the third peak wavelength being smaller than the fourth peak wavelength, and the third spectral width being larger than the fourth spectral width; and wherein the second and/or third luminescent material comprises a red emitting Eu2+ phosphor.
