Abstract
A cooling device for cooling a light source located in an automotive luminous device. This cooling device includes a heat sink intended to be in thermal contact with the light source, a plurality of fins in direct thermal contact with the heat sink, a plurality of pins in direct thermal contact with the heat sink and a fan. The fan is arranged to make a fluid flow from an inlet of the cooling device to an outlet to the cooling device, so that the plurality of fins are nearer the inlet than the plurality of pins.
