Light-emitting diode chip comprising a converter layer and method of making a light-emitting diode chip comprising a converter layer |
摘要 |
Disclosed is a light-emitting diode chip comprising a semiconductor layer sequence suitable for emitting primary electromagnetic radiation and further comprising a converter layer that is applied to at least one main face of the semiconductor layer sequence and comprises at least one phosphor suitable for converting a portion of the primary radiation into secondary radiation, at least a portion of the secondary radiation and at least a portion of the unconverted primary radiation overlapping to form a mixed radiation with a resulting color space. The converter layer is purposefully structured to adjust a dependence of the resulting color space on viewing angle. Also disclosed is a method of making a light-emitting diode chip in which a converter layer is purposefully structured.
