Abstract:
1. A motor vehicle headlamp with a light-emitting diode arrangement which is provided as a light source of the motor vehicle, comprising: at least one light-emitting diode chip, each light-emitting diode chip being assigned at least one optical element; at least one heat-conducting element configured to dissipate heat generated by the at least one light-emitting diode chip; and at least one cooling apparatus configured to conduct the heat carried away by the heat-conducting element; wherein the at least one cooling apparatus conducts the heat generated by the at least one light-emitting diode chip of the light-emitting diode arrangement to one of a covering glass and an optical element of the motor vehicle headlamp for heating said one of the covering glass and the optical element; wherein the at least one cooling apparatus comprises at least one of a heat pipe and wire; and wherein the at least one cooling apparatus is in direct contact with at least one of the covering glass and the optical element to conduct the generated heat to the at least one of the covering glass and the optical element.
