Abstract

Module d’éclairage de projecteur de véhicule automobile et projecteur associé [La présente invention concerne un module d’éclairage (10) de projecteur de véhicule automobile, comprenant : un dispositif lumineux (12) comprenant une source lumineuse (24) ; et un dispositif (16) de conversion de longueur d’onde dudit rayonnement lumineux, ledit dispositif de conversion comprenant une couche luminophore (48). Le dispositif lumineux est apte à émettre un rayonnement lumineux (38) vers la couche luminophore selon une première direction (40). Le dispositif de conversion est apte à émettre un faisceau lumineux dans une deuxième direction (23), inclinée (α) par rapport à la première direction, sous l’effet du rayonnement lumineux du premier dispositif lumineux. La couche luminophore (48) est transparente à au moins une partie du spectre de lumière visible. Ainsi, la couleur de ladite couche luminophore est peu ou pas visible depuis l’extérieur du véhicule. Figure pour l’abrégé : Figure 1]Motor vehicle headlamp lighting module and associated headlamp [The present invention relates to a motor vehicle headlamp lighting module (10), comprising: a light device (12) comprising a light source (24); and a device (16) for wavelength converting said light radiation, said converting device comprising a phosphor layer (48). The light device is capable of emitting light radiation (38) towards the phosphor layer in a first direction (40). The conversion device is capable of emitting a light beam in a second direction (23), inclined (α) with respect to the first direction, under the effect of light radiation from the first light device. The phosphor layer (48) is transparent to at least a portion of the visible light spectrum. Thus, the color of said phosphor layer is little or not visible from outside the vehicle.
