Abstract
In a vehicle lighting system where multiple lighting units are arranged to be sequentially displaced towards the rear of the lighting unit in the direction of the vehicle width, heat generation can be efficiently suppressed. [Solution] The system is configured such that a blower fan 50 and a support bracket 60 for supporting it are arranged in the space Sr behind the three lamp units 20A, 20B, and 20C within the lamp chamber. The blower fan 50 is positioned behind the central lamp unit 20B and is configured to blow air from the space Sr behind the lamp unit beyond the support bracket 60 towards the space Sf in front of the lamp unit. Furthermore, a rectifier plate 70 is arranged in the space Sf in front of the lamp unit to direct a portion of the air blown out from the blower fan 50 towards the lamp unit 20C located at the outer end in the vehicle width direction. This makes it possible to efficiently suppress heat generation in the lamp unit 20C located at the outer end in the vehicle width direction.
