Abstract:
(EN) This vehicle headlight (1), which is an aspect of a vehicle illumination lamp, is provided with: light sources (52R, 52G, 52B); and diffraction gratings (54R, 54G, 54B) that diffract light incident from the light sources (52R, 52G, 52B). The light diffracted by the diffraction gratings (54R, 54G, 54B) is emitted in a predetermined light distribution pattern. A projection area (AR) to which are projected components (LCR, LCG, LCB) that advance and pass through the diffraction gratings (54R, 54G, 54B) among the light incident upon the diffraction gratings (54R, 54G, 54B), is positioned below the light distribution pattern and within a range (RNG) in which the field of view of the driver of the vehicle is obstructed by the vehicle.
(FR) La présente invention concerne un phare de véhicule (1), qui est un aspect d'une lampe d'éclairage de véhicule, comportant : des sources lumineuses (52R, 52G, 52B) ; et des réseaux de diffraction (54R, 54G, 54B) qui diffractent la lumière incidente des sources lumineuses (52R, 52G, 52B). La lumière diffractée par les réseaux de diffraction (54R, 54G, 54B) est émise selon une configuration de distribution de lumière prédéterminée. Une zone de projection (AR), sur laquelle sont projetées des composantes (LCR, LCG, LCB) qui progressent et passent à travers les réseaux de diffraction (54R, 54G, 54B) parmi la lumière incidente sur les réseaux de diffraction (54R, 54G, 54B), est placée sous le motif de distribution de lumière et dans une portée (RNG) dans laquelle le champ de vision du conducteur du véhicule est obstrué par le véhicule.
(JA) 車両用照明灯具の一形態である車両用前照灯(1)は、光源(52R,52G,52B)と、当該光源(52R,52G,52B)から入射する光を回折する回折格子(54R,54G,54B)とを備える。回折格子(54R,54G,54B)により回折される光は、所定の配光パターンで照射される。回折格子(54R,54G,54B)に入射する光のうち回折格子(54R,54G,54B)を直進して透過する成分(LC,LC,LC)が投影される投影領域(AR)は、配光パターンよりも下側であり、車両の運転者の視界が前記車両により妨げられる範囲(RNG)内に位置する。
