Abstract:
1. A light emitting diode arrangement comprising a light emitting diode with a light emitting crystal electrically connected to an anode and a source, characterized in that one of the anode and the source is thermally coupled to a first heat conductor, the heat conductor being thermally coupled to one or more Peltier elements to, in a first mode, convert thermal energy transmitted from and generated in the light emitting crystal when the light emitting crystal is provided with electrical energy at a first level into electrical energy, and further comprising a control unit adapted to drive the light emitting diode between the first mode and a second mode, wherein in the second mode, electrical energy of a second level is provided to the light emitting diode and electrical energy is provided to the one or more Peltier elements to cool the one or more Peltier elements and to thus actively cool the light emitting diode via the one or more Peltier elements.
