Abstract

Un bloc optique, par exemple d’un véhicule, comprend un boîtier logeant un dispositif lumineux (DL) délivrant des photons assurant une première fonction photométrique, et un support (SG) réalisé par moulage et comportant au moins une paroi (PS) délimitant une gorge (G1) dans laquelle est installé un guide de lumière (GL1) délivrant des photons assurant une seconde fonction photométrique, et comportant une partie (PP) définissant une paroi de séparation avec ce dispositif lumineux (DL) et logeant une extrémité (E22) du guide de lumière (GL1). Cette partie (PP) comprend une sous-partie terminale (SPT) définissant une cavité monobloc (CM) logeant fixement, en la masquant, cette extrémité (E22), et agencée de manière à empêcher un passage de photons entre cette gorge (G1) et ce dispositif lumineux (DL).
