Abstract:
The invention provides a lighting device ( 100 ) comprising a first light source ( 10 ) and a second light source ( 20 ), a control system ( 50 ) configured to control the first light source ( 10 ) and the second light source ( 20 ), wherein the first light source ( 10 ) is configured to provide first light source light ( 11 ) having a correlated color temperature (CCT) of at maximum 3000 K and a color rendering index (CRI) of at least 75, and wherein the second light source ( 20 ) is configured to provide second light source light ( 21 ) having a dominant wavelength selected from the range of (575-780) nm and having a color rendering index of at maximum ( 70 ).

Claim (Index 1):
A lighting device comprising a first light source configured to provide first light source light, a second light source configured to provide second light source light and a control system configured to control the light first source and the second light source to provide said first light source light and second light source light respectively,\n wherein the first light source light and the second light source light each have a melanopsin effectiveness factor MEF of a maximum 0.4 and wherein MEF is defined as MEF = 1.22 \u00b7 \u2211 \u03bb = 380 \ue89e \ue89e nm \u03bb = 780 \ue89e \ue89e nm \ue89e ( SPD \ue8a0 ( \u03bb ) \u00b7 m \ue8a0 ( \u03bb ) ) \u2211 \u03bb = 380 \ue89e \ue89e nm \u03bb = 780 \ue89e \ue89e nm \ue89e ( SPD \ue8a0 ( \u03bb ) \u00b7 V \ue8a0 ( \u03bb ) ) wherein SPD( ) defines the spectral power distribution of the light source light emitted by the respective light source, wherein m( ) is the normalized melanopic sensitivity function and wherein V( )) is the normalized photopic sensitivity function, and\n wherein the first light source light and the second light source light have a color rendering index CRI differing at least 15 CRI units from each other.
