摘要：
The invention provides a lighting device (100) with light emitting diodes (10) configured to generate light (11) having a wavelength selected from the range of 400-475 nm, wherein the lighting device (100) comprises at least two light emitting parts (100a, 100b). The first light emitting part (100a) comprises a first subset (10a) of light emitting diodes (10), and is configured to provide a first light (111a) having the first spectral light distribution substantially in the range of 400-475 nm. The second light emitting part (100b) comprises a second subset (10b) of light emitting diodes (10) and comprising a light conversion element (20) configured to convert at least part of the light (11) generated from the second subset (10b) of the plurality of light emitting diodes (10) into the second light (111b), with the second spectral light distribution substantially in the range of 625-800 nm. The first subset (10a) of the plurality of light emitting diodes (10) and the second subset (10b) of the plurality of light emitting diodes (10) are independently controllable.
