Abstract
(DE)
Die Erfindung betrifft eine Beleuchtungsvorrichtung für Fahrzeuge mit einem ersten Lichtmodul (1) enthaltend eine Lichtquelle (2) und eine Optikeinheit (3) zur Erzeugung eines ersten Ausleuchtbereiches (A1), mit einem zweiten Lichtmodul (4) enthaltend eine Lichtquelle (5) und eine Optikeinheit (6) zur Erzeugung eines zweiten Ausleuchtbereiches (A2), mit einer Ansteuereinheit (10) zur Ansteuerung des ersten Lichtmoduls (1) und des zweiten Lichtmoduls (4), so dass bezogen auf eine gleichgroße Fläche in dem ersten Ausleuchtbereich (A1) eine größere Anzahl von Lichtpixeln (L1) abgebildet wird als in dem zweiten Ausleuchtbereich (A2), wobei die Lichtpixel (L1) des ersten Lichtmoduls (1) eine größere Beleuchtungsstärke aufweisen als die Lichtpixel (L2) des zweiten Lichtmoduls (4), dass die Ansteuereinheit (10) auf die Lichtquellen (2, 5) des ersten Lichtmoduls (1) bzw. des zweiten Lichtmoduls (4) derart einwirkt, dass die Lichtquellen (2, 5) des ersten und zweiten Lichtmoduls (1, 4) jeweils im eingeschalteten Zustand der Lichtquellen (2, 5) mit einer thermischen Leistung innerhalb eines Toleranzbandes (T) und unterhalb einer maximalen thermischen Leistung (Pmax), der mindestens eine Lichtquelle (2, 5) betrieben werden.
(EN)
The invention relates to an illumination device for vehicles, comprising a first light module (1) having a light source (2) and an optical unit (3) for generating a first illumination region (A1), comprising a second light module (4) having a light source (5) and an optical unit (6) for generating a second illumination region (A2), comprising a control unit (10) for controlling the first light module (1) and the second light module (4) so that a larger number of light pixels (L1) is imaged in the first illumination region (A1) than in the second illumination region (A2) with respect to a surface of equal size, wherein the light pixels (L1) of the first light module (1) have a greater illumination intensity than the light pixels (L2) of the second light module (4). The control unit (10) acts upon the light sources (2, 5) of the first light module (1) and the second light module (4) in such a way that when the light sources (2, 5) are activated, said light sources (2, 5) of the first and the second light module (1, 4) are each operated with a thermal power within a tolerance band (T) and below a maximum thermal power (Pmax) of the at least one light source (2, 5).
(FR)
L’invention concerne un dispositif d’éclairage destiné à des véhicules, comportant un premier module lumineux (1) contenant une source lumineuse (2) et une unité optique (3) servant à produire une première zone d’éclairage (A1), un second module lumineux (4) contenant une source lumineuse (5) et une unité optique (6) servant à produire une seconde zone d’éclairage (A2), et une unité d’activation (10) servant à activer le premier module lumineux (1) et le second module lumineux (4), de sorte que par rapport à une surface de même taille, le nombre de pixels lumineux (L1) reproduits dans la première zone d’éclairage (A1) est plus grand que dans la seconde zone d’éclairage (A2), les pixels lumineux (L1) du premier module lumineux (1) présentant une intensité d’éclairage plus grande que celle des pixels lumineux (L2) du second module lumineux (4). L’unité d’activation (10) agit sur les sources lumineuses (2, 5) du premier module lumineux (1) ou du second module lumineux (4) de telle manière que lorsqu’elles sont en circuit, les sources lumineuses (2, 5) du premier et du second module lumineux (1, 4) fonctionnent respectivement, à l'état activé des sources lumineuses (2, 5), à une puissance thermique située à l’intérieur d’une plage de tolérance (T) et inférieure à une puissance thermique maximale (Pmax) de la ou des sources lumineuses (2, 5).
