Abstract
Titre La présente invention concerne un dispositif lumineux (1) comprenant un premier module lumineux (100) comprenant un premier dissipateur thermique (111), un deuxième module lumineux (200) comprenant un deuxième dissipateur thermique (211), au moins l’un des dissipateurs thermiques (111, 211) comporte une base (113, 213) sur laquelle sont disposés des éléments de dissipation thermique (115, 215) qui émergent d’une face de la base, et un organe de ventilation (300) agencé entre le premier dissipateur thermique (100) et le deuxième dissipateur thermique (200). Au moins un des dissipateurs thermiques comprend un logement (117, 217) au moins en partie bordé par des éléments de dissipation thermique (115, 215), l’organe de ventilation étant au moins en partie disposé dans ce logement (117, 217). (figure 1)
