Abstract

GUIDE DE LUMIÈRE ET LAMPE DE VÉHICULE Un guide de lumière (112) pour une lampe de véhicule (100) inclut une partie en forme de barre (116) et une partie en forme de plaque (118). La partie en forme de barre (116) inclut une partie de guide de lumière en forme de barre (120) et une partie de raccordement en saillie (122) faisant saillie d’une surface périphérique (120c) de la partie de guide de lumière en forme de barre et s’étendant le long de la partie de guide de lumière en forme de barre (120). La partie en forme de plaque (118) inclut deux surfaces principales se faisant face, et une surface latérale de la partie en forme de plaque (118c) raccordant les deux surfaces principales. Le guide de lumière (112) est un produit moulé multicolore dans lequel la partie en forme de barre (116) est formée d’un premier matériau de résine, et la partie en forme de plaque (118) est formée d’un second matériau de résine contenant un agent de diffusion de la lumière. La partie de guide de lumière en forme de barre (120) est raccordée à la surface latérale (118c) de la partie en forme de plaque (118) par la partie de raccordement en saillie (122). Figure 2
