    Abstract: The invention provides alighting unit (100) comprising a light source (10) and a light conversion layer (20). The light source (10) comprises a light emitting diode (LED) (110) and a first luminescent material layer (120) in physical contact with a light emitting surface (115) of the LED (110). The first luminescent material layer (120) comprises a first luminescent material (130), configured to convert at least part of LED light (111) into light (131) having a red component. The light source (10) is configured to generate light (11) having a blue component and having the red component of the light (131). The light conversion layer (20), configured at a non-zero distance (d) from the light source (10), comprises a second luminescent material (30) configured to convert at least part of the light (11) into light (31). The lighting unit (100) is configured to provide white lighting unit light (111).

    Abstract: A phosphor converted Light Emitting Diode (LED), a lamp and a luminaire are provided. The phosphor converted LED comprises a LED, a first luminescent material, a second luminescent material and a third luminescent material. The LED emits a first spectral distribution having a first peak wavelength in the blue spectral range. The first luminescent material absorbs a portion of the light of the first spectral distribution and converts at least a portion of the absorbed light towards light of a second spectral distribution. The second spectral distribution has a second peak wavelength in the green spectral range. The second luminescent material absorbs absorbing a portion of the light of the first spectral distribution and/or a portion of the second spectral distribution. The second luminescent material converts at least a portion of the absorbed light towards lights of a third spectral distribution. The third spectral distribution has a third spectral width and has a third peak wavelength. The third luminescent material absorbs a portion of the light of at least one of the first spectral distribution, second spectral distribution, and the third spectral distribution. The third luminescent material converts at least a portion of the absorbed light towards light of a fourth spectral distribution. The fourth spectral distribution has a fourth spectral width and has a fourth peak wavelength. The third peak wavelength and the fourth peak wavelength are in the orange/red spectral range. The third peak wavelength is smaller than the fourth peak wavelength and the third spectral width is larger than the fourth spectral width.
