  • FIG. 8B is a view for explaining the traveling direction of the light from the high beam side LED light source 81 in the side view of the vehicle.
  • the light emitted from the high beam side LED light source 81 passes through the hole 82 b on the high beam side, and is emitted below the partition wall 93. Furthermore, light from the high beam side LED light source 81 is reflected by the front reflection surface 101 of the second reflection surface 99 as shown by the arrow (4), and is irradiated in a substantially horizontal direction in front of the vehicle. As a result, the lower light emitting unit 121 below the partition wall 93 emits light.

Abstract

La présente invention aborde le problème de la réalisation d'un phare dans lequel la surface de la partie d'émission de lumière du phare peut être agrandie même pendant l'éclairage par feu de croisement. L'invention réalise à cet effet un phare (60) pourvu d'un boîtier (61) et d'une cloison (93) destinée à diviser une ouverture (92) en des sections supérieure et inférieure. Un réflecteur (91) comprend une première surface réfléchissante (96) produite pour la portion au-dessus de la cloison (93) et une deuxième surface réfléchissante (99) produite pour la portion au-dessous de la cloison (93). Une source de lumière à LED côté feu de croisement (71) est disposée à la position à laquelle la première surface réfléchissante (96) est éclairée, et une source de lumière à LED côté feu de route (81) est disposée à la position à laquelle la deuxième surface réfléchissante (99) est éclairée. La cloison (93) est pourvue d'un espace de guidage de lumière (90) destiné à guider la lumière émise depuis la source de lumière à LED côté feu de croisement (71) vers la surface réfléchissante côté feu de route. L'invention permet ainsi d'augmenter la surface de la partie d'émission de lumière du phare, même pendant l'éclairage par feu de croisement.
