Abstract

Dans cette lampe de véhicule comprenant une plaque de guidage de lumière, la configuration de la plaque de guidage de lumière est simplifiée, le degré de liberté de la forme de motif d'un motif d'émission de lumière est amélioré, et un corps de guidage de lumière est facilement conçu et fabriqué. La lampe de véhicule comprend : une source de lumière 1 (11) ; et une plaque de guidage de lumière 2 (corps de guidage de lumière) qui présente une surface avant et une surface arrière et qui guide la lumière provenant de la source de lumière vers l'intérieur de celle-ci. La plaque de guidage de lumière 2 a, sur la surface arrière, une pluralité de gradins de réflexion de lumière 3 qui réfléchissent la lumière guidée vers l'intérieur et émet la lumière à partir de la surface avant, et un motif d'émission de lumière souhaité est formé par la lumière réfléchie par les gradins de réflexion de lumière 3 et émise à partir de la surface avant de la plaque de guidage de lumière 2. De plus, la pluralité de gradins de réflexion de lumière 3 comprend une pluralité de premiers gradins de réflexion de lumière 31 qui réfléchissent, vers une direction souhaitée, une lumière guidée dans la plaque de guidage de lumière 2. Les directions de la lumière réfléchie par la pluralité de premiers gradins de réflexion 31 et émise à partir de la plaque de guidage de lumière 2 sont différentes l'une de l'autre.
