Abstract (en)
[origin: EP2187121A1] The sink has fins (6,7) comprising bases (14) for carrying light sources (2) i.e. electroluminescent diodes, of optical modules (1), where the fins (7) are junction fins i.e. side fins, constituting a junction body between the bases. The light sources of the optical modules are associated to an optical system (4). The junction fins are oriented in orthogonal plane to an emergence direction (D) of the light out of the optical modules. Operation power of the light sources is higher than 2 watt.
