Abstract: The present invention pertains to a heat exchange system (100) of a vehicle lighting device. The heat exchange system (100) includes an air duct (10) that is arranged facing a heat sink (20) for transferring heat by the light sources of the lighting device. The air duct (10) comprises an air inlet portion (12) comprising a first air passage area (120) receiving an airflow (22) into the air duct (10) and an air outlet portion (14) comprising a second air passage area (140) directing the airflow (22) towards a heatsink (20). In addition, an intermediate portion (16) is disposed between the air inlet portion (12) and the air outlet portion (14). The intermediate portion (16) is having a variable cross-section in a non-linear way. The largest section of the intermediate portion (160) is superior to the section of both the first air passage area (120) and the second air passage area (140).
