Abstract (en)
[origin: WO2008043324A1] The invention relates to an LED semiconductor element comprising at least one first radiation-generating active layer and at least one second radiation-generating active layer which is stacked on top of the first active layer in a vertical direction and is serially connected to the first active layer. The first active layer and the second active layer are connected in an electrically conducting manner by means of a contact zone. The invention further relates to different uses of said LED semiconductor element.
