Abstract

L'invention concerne l'alignement d'une section de projecteur, sa séparation d'une section de tête, sur un côté sur lequel un miroir est prévu dans la section de tête. Un trajet de lumière réfléchi par le miroir est placé plus loin que la section projecteur sur un côté dans une direction croisant une direction dans laquelle la section de tête et la section projecteur sont alignées. Une section de paroi sur le côté section de tête dans un boîtier a une section recouverte et une section d'extension. La section recouverte est recouverte par la section de tête et comporte une section d'émission ayant une lumière de projection émise à partir de celle-ci. La section d'extension s'étend vers le côté opposé au côté trajet de la lumière réfléchie, par rapport à un espace entre la section recouverte et la section de tête. Un orifice d'échappement qui évacue l'air depuis l'intérieur du boîtier est formé dans cette section d'extension, sur le côté opposé au côté espace.
