Abstract

An arrangement for cooling semiconductor light sources (5), wherein the semiconductor light sources (5) are arranged on a heat-conducting module (11), which is operatively connected to an evaporator zone (27) of a heat pipe (20), wherein a first condensation zone (23) of the heat pipe (20) is connected to a first heat sink (33), wherein the heat pipe (20) is connected to at least one second condensation zone (25) with at least one second heat sink (25), and a heat flow can be switched over between the condensation zones (23, 25) or the second condensation zone (25) can be switched in.
