Title
(DE) LEUCHTEINRICHTUNG FÜR EIN FAHRZEUG
(EN) LIGHTING DEVICE FOR A VEHICLE
(FR) DISPOSITIF D'ÉCLAIRAGE DE VÉHICULE
Abstract
(DE)
Es wird eine Leuchteinrichtung bereitgestellt, umfassend eine räumlich ausgedehnte Lichtquelle mit einer Leuchtfläche größer als 0,5 mm2 sowie eine asphärische TIR-Linse, die eingerichtet ist, Licht von der räumlich ausgedehnten Lichtquelle zu kollimieren und einen refraktiven Diffuser, der zum Erzeugen einer Leuchtverteilung auf Basis des kollimierten Lichts eingerichtet ist.
(EN)
A lighting device is provided, comprising a spatially extended light source with an emitting surface greater than 0.5 mm² and an aspheric TIR lens, which is configured to collimate light from the spatially extended light source, and a refractive diffuser, which is configured to generate a light distribution on the basis of the collimated light.
(FR)
L'invention concerne un dispositif d'éclairage, comprenant une source lumineuse spatialement étalée présentant une surface d'émission lumineuse supérieure à 0,5 mm2 ainsi qu'une lentille à réflexion totale interne - TIR - asphérique conçue pour collimater la lumière de la source spatialement étalée, et un diffuseur de réfraction conçu pour générer une répartition lumineuse sur la base de la lumière collimatée.
