Abstract (en)
[origin: WO2011018411A1] A radiation-emitting semiconductor component is provided, comprising: a light-emitting diode chip (1) having at least two emission regions (2a, 2b) that can be operated independently of each other, at least two differently designed conversion elements (31, 32), wherein during operation of the light-emitting diode chips (1) each of the emission regions (2a, 2b) is provided for generating electromagnetic primary radiation, each emission region (2a, 2b) has an emission surface (21, 22) by which at least part of the primary radiation is decoupled from the light-emitting diode chip (1), the conversion elements (31, 32) are provided for absorbing at least part of the primary radiation and for re-emitting secondary radiation, the differently designed conversion elements (31, 32) are disposed downstream of different emission surfaces, and an electric resistance element (4), which is connected in series or parallel to at least one of the emission regions (2a, 2b).
