Abstract

L'invention concerne un dispositif d'éclairage de véhicule (10) comprenant un boîtier (1), une pluralité de sources lumineuses à semi-conducteurs (2) installées dans le boîtier (1), un barillet de support (3), un élément de maintien (4) et une pluralité de lentilles (5). Le barillet de support (3) comprend une surface de canon (30) et une saillie de support (31) qui dépasse de la surface de canon (30). L'élément de support (4) est agencé pour coupler la saillie de support (31) au boîtier (1). La pluralité de lentilles (5) sont supportées dans le barillet de support (3) et sont configurées pour projeter le motif lumineux des sources de lumière (2). Le corps de support (3) comprend en outre au moins un élément en saillie (6) qui dépasse de la surface du corps (30) d'une distance supérieure à celle de la saillie du support (31).Figure pour l'abrégé : figure 1
