Abstract
Official abstract text for this publication.
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 ).
