Abstract (en)
[origin: WO2018091803A1] The invention relates to a lighting device (DE) comprising a light source (SL) for delivering, to a predefined site (EP), photons having at least one photometric function, and a screen (EC) placed in front of the predefined site (EP) and comprising alternating first (Z1) and second (Z2) zones respectively having a first light transmission coefficient and a second light transmission coefficient which is strictly lower than the first, such that the intensity of the light resulting from the photons passing through each first zone (Z1) is strictly higher than the intensity of the light resulting from the photons passing through each second zone (Z2).
