Abstract
(EN)
This vehicular lamp (10) is provided with: a laser source unit (20) configured to generate white light by causing a laser beam emitted from a laser source (24) to be incident on a wavelength conversion element (26) and to emit the white light; and a light-distribution control member (12) configured to form a desired light-distribution pattern by controlling the light emitted from the laser source unit (20). The laser source unit (20) is provided with a reflection control member (30) for causing the laser beam emitted from the laser source (24) to be reflected so as to scan over the wavelength conversion element (26), and a light-path change member (28) for changing light paths of at least some of the laser beam reflected by the reflection control member (30) is disposed between the reflection control member (30) and the wavelength conversion element (26).

Selon la présente invention, ce phare de véhicule (10) comprend : une unité de source laser (20) configurée pour générer une lumière blanche en amenant un faisceau laser émis par une source laser (24) à être incident sur un élément de conversion de longueur d'onde (26) et pour émettre la lumière blanche ; et un élément de commande de distribution de lumière (12) configuré pour former un motif de distribution de lumière souhaité par commande de la lumière émise par l'unité de source laser (20). L'unité de source laser (20) comprend un élément de commande de réflexion (30) servant à amener le faisceau laser émis par la source laser (24) à être réfléchi de façon à balayer l'élément de conversion de longueur d'onde (26), et un élément de changement de trajet de lumière (28) servant à changer des trajets de lumière d'au moins une partie du faisceau laser réfléchi par l'élément de commande de réflexion (30) est disposé entre l'élément de commande de réflexion (30) et l'élément de conversion de longueur d'onde (26).
