| 摘要 |
The invention provides a lighting device (100) configured to generate lighting device light (101), wherein the lighting device light (101) includes an emission band (110) in the visible part of the spectrum which represents at least 80% of the total power (W) of the lighting device light (101) in the visible part of the spectrum, wherein the emission band (110) has a full width half maximum of at maximum 60 nm, and wherein the emission band (110) has a peak maximum (MM3), wherein said emission band (110) comprises luminescent material light (21), wherein the lighting device (100) comprises (i) a solid state-based light source (10), configured to generate light source light (11) having a peak maximum (MX2), and (ii) a luminescent material (20), configured to convert at least part of the light source light (11) into said luminescent material light (21), wherein the solid state-based light source (10) is configured to provide said light source light (11) with 0 < MM3-MX2 < 60 nm. |
