COOLING DEVICE

This invention provides a cooling device (1) for cooling a light source comprised in an automotive lighting device. The cooling device (1) comprises a heat sink (2) and a flow guide (3). The heat sink (2) has a source point (21) intended to receive a light source, the source point (21) being in thermal contact with the rest of the heat sink (2), the heat sink (2) further comprising a heater (22) where heat from the heat sink (2) is communicated from the source point to ambient air, thus generating heated ambient air. The flow guide (3) comprises an input (31) and an output (32), in such a way that heated ambient air is intended to flow from the input (31) to the output (32), the input (31) being in fluid contact with the heated ambient air and the output (32) being in fluid contact with the source point (21) so that when the heated ambient air flows from the input (31) to the output (32), further heat may be evacuated from the source point (21).
