Abstract:
The invention provides a lighting device ( 100 ) comprising a solid state light source ( 10 ) configured to provide blue light ( 11 ) having a dominant wavelength selected from the range of 440-490 nm, a first luminescent material ( 210 ) configured to convert part of the blue light ( 11 ) into first luminescent material light ( 211 ) having intensity in one or more of the green and yellow having a CIE u′ ( 211 ), and a second luminescent material ( 220 ) configured to convert part of one or more of the blue light ( 11 ) and the first luminescent material light ( 211 ) into second luminescent material light ( 221 ) having intensity in one or more of the orange and red having a CIE u′ ( 221 ), wherein the first luminescent material ( 210 ) and the second luminescent material ( 220 ) are selected to provide said first luminescent material light ( 211 ) and said second luminescent material light ( 221 ) defined by a maximum ratio of CIE u′ ( 211 ) and CIE u′ ( 221 ) being CIE u′( 221 )=1.58*CIE u′( 211 )+0.255, and a minimum ratio of CIE u′ ( 211 ) and CIE u′ ( 221 ) being CIE u′( 221 )=2.3*CIE u′( 211 )+0.04.

Claim (Index 11):
The light emitting device according to  claim 1 , wherein the second luminescent material comprises MAlSiN 3 :Eu, wherein M is one or more elements selected from the group consisting of barium, strontium and calcium.
