Light projection device comprising a projector with a casing (1) with at least one lighting element (2), a heat sink (3), a fan (4) and a connection element (5) for fixing it to a rail, wherein the projector has front and rear openings (6,7) delimited by a support element (8) of a reflector (9) and by a rear cap (10) and wherein the openings are communicated through longitudinal passages (11), which determine areas of passage of the cooling air, suctioned by the fan (4) through the rear opening (7) and driven towards the front opening (6), avoiding in this way to expose the fan to the heat released by the lighting elements and that the device overheats. |
