Abstract (en)

[origin: EP2278218A2] The headlight has a cooling device (50) comprising a thermal cooling element coupled with a heat source (20). A blower generates cooling airflow (40). The cooling element and a blower housing form one-piece structural cooling element-blower housing-units (52). The blower is formed as a radial blower or a diagonal blower with a blower wheel (60) that is rotatable in the blower housing. The cooling element-blower housing-units are formed as stators. The heat source is arranged on an outer wall of the cooling element-blower housing-units.
