Abstract (en)
[origin: EP2199669A1] The device has an optical module (2) equipped with a cooling unit (5) having a thermal exchange surface, where the optical module has an LED (3) i.e. power LED, that is thermally contacted with the cooling unit. A heat conductor (8) e.g. heat pipe, has an end (9) that is placed at a distance from the cooling unit, where the end is equipped with deflectors. A space between the deflectors constitutes an air flow guiding channel (11), where the channel is opened on a passage (7) defined between vanes (6).
