Title (EN) LASER BASED LIGHT SOURCE WITH TAILORED ILLUMINATION PATTERN
(FR) SOURCE DE LUMIÈRE À BASE DE LASER AVEC MOTIF D'ÉCLAIRAGE PERSONNALISÉ
Abstract:
(EN) A vehicle headlight has a laser-based light source (100) comprising: • - a laser (110) for emitting laser light, • - a light converting device (130) with a light converter for converting the laser light to converted light with a peak emission wavelength greater than a peak emission wavelength of the laser light, and • - an optical arrangement (150) for providing a transformed focused image (11') of the laser (110) on the light converter, thereby broadening the image (11) in at least a first direction (51) perpendicular to an optical axis (50) of the laser-based light source (100), such broadening being independent from a second direction (52) being perpendicular to the optical axis (50) and to the first direction (51), wherein the optical arrangement (150) is adapted to broaden the image of the laser by providing at least two overlapping images (11a - Ilk) of the laser (110) on the light converter (130) broadened in at least the first direction (51).
(FR) Un phare de véhicule a une source de lumière à base de laser (100) comprenant : •-un laser (110) pour émettre une lumière laser, •-un dispositif de conversion de lumière (130) avec un convertisseur de lumière pour convertir la lumière laser en une lumière convertie ayant une longueur d'onde d'émission de pic supérieure à une longueur d'onde de pic d'émission de la lumière laser, et •-un agencement optique (150) pour fournir une image focalisée transformée (11') du laser (110) sur le convertisseur de lumière, élargissant ainsi l'image (11) dans au moins une première direction (51) perpendiculaire à un axe optique (50) de la source de lumière laser (100), un tel élargissement étant indépendant d'une seconde direction (52) perpendiculaire à l'axe optique (50) et à la première direction (51), l'agencement optique (150) étant conçu pour élargir l'image du laser en fournissant au moins deux images chevauchantes (11a-Ilk) du laser (110) sur le convertisseur de lumière (130) élargi dans au moins la première direction (51).
