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).
