In a discharge lamp lighting apparatus for lighting a lighting system using a discharge lamp, a housing used for containing a printed circuit board on which a discharge lamp lighting circuit is mounted is formed by resin molding. In order to put out wires connected to the printed circuit board from an inside to outside of the housing, protruding portions are protruded outward from upper end portions of a front face and a rear face of side walls of a base member which constitute the housing, and wire putting grooves are formed on upper faces of the protruding portions. Furthermore, reinforcing ribs are provided for coupling the protruding portions and portions of the side walls except the protruding portions so as to reinforce mechanical strength of the protruding portions by the reinforcing ribs.

L'invention concerne un dispositif d'éclairage à lampe à décharge destinée à éclairer un illuminateur au moyen d'une lampe à décharge, un logement stockant une carte de circuit imprimé présentant un circuit d'éclairage de lampe à décharge formée par moulage de résine. De manière à sortir un fil électrique relié à la carte de circuit imprimé de l'intérieur du logement, une projection est projetée vers l'extérieur des extrémités supérieures des surfaces avant et arrière de la paroi latérale d'un élément de base constituant le logement, et une rainure déviant le fil électrique est formée sur la surface supérieure de la projection. De plus, une nervure de renfort est installée pour relier la projection à l'autre partie de la paroi latérale de projection, la nervure de renforcement augmentant la force mécanique de la projection.
