Abstract
(EN)
A vehicle light fixture comprises: a first distributed-light irradiation unit that irradiates a first distributed light forward of a vehicle; and a second distributed-light irradiation unit that irradiates a second distributed light having a bright-dark boundary line at least to the side of the vehicle. Illumination of the first distributed-light irradiation unit and the second distributed-light irradiation unit is controlled in accordance with prescribed operations by a driver of the vehicle on the first distributed-light irradiation unit. The second distributed-light irradiation unit illuminates in coordination with the illumination of the first distributed-light irradiation unit. The second distributed light irradiation unit comprises: a light source; and a projection lens that projects light emitted from the light source, forms an irradiation pattern surrounded by a plurality of light-dark boundary lines, and irradiates forward of the vehicle. The projection lens focuses the light emitted from the light source more moving outward from the light axis of the projection lens, and collects and emphasizes the light emitted from the light source on at least some of the plurality of light-dark boundary lines.

L'invention concerne un appareil d'éclairage de véhicule comprenant : une première unité de rayonnement lumineux distribué, qui rayonne une première lumière distribuée vers l'avant d'un véhicule ; et une seconde unité de rayonnement lumineux distribué, qui rayonne une seconde lumière distribuée présentant une ligne de limite de clair-obscur au moins sur le côté du véhicule. L'éclairage de la première unité de rayonnement lumineux distribué et de la seconde unité de rayonnement lumineux distribué est commandé conformément à des opérations prescrites par un conducteur du véhicule, sur la première unité de rayonnement lumineux distribué. La seconde unité de rayonnement lumineux distribué éclaire en coordination avec l'éclairage de la première unité de rayonnement lumineux distribué. La seconde unité de rayonnement lumineux distribué comprend : une source lumineuse ; et une lentille de projection, qui projette de la lumière émise à partir de la source lumineuse, qui forme un motif de rayonnement entouré par une pluralité de lignes de limite de clair-obscur et qui rayonne vers l'avant du véhicule. La lentille de projection focalise la lumière émise à partir de la source lumineuse plus en mouvement vers l'extérieur de l'axe de lumière de la lentille de projection et collecte et met en évidence la lumière émise par la source lumineuse sur au moins une partie de la pluralité de lignes de limite de clair-obscur.
