US 2006/0076572 A1 · Light-emitting diode arrangement and motor vehicle headlamp

Abstract

A light-emitting diode arrangement having at least one light-emitting diode chip (1), each light-emitting diode chip (1) being assigned at least one optical element (4). In addition, the light-emitting diode arrangement has at least one heat-conducting element (13) which is suitable to carry away the heat generated by the light-emitting diode chip, and at least one cooling apparatus which is suitable to carry heat away from the heat-conducting element. The light-emitting diode arrangement is particularly well suited, for example, to use in motor vehicle headlamps.
