1. A white light emitting semiconductor component, comprising:

  • a semiconductor body having a layer sequence suitable for emitting electromagnetic radiation of a first wavelength range comprising at least blue light during an operation of the semiconductor component;

    a luminescence conversion layer being disposed directly on said semiconductor body and having a substantially constant thickness and containing at least one luminescent conversion material, said luminescence conversion material being suitable for absorbing a radiation originating from the first wavelength range and emitting light in at least a portion of a second wavelength range consisting of green, yellow, and red, a part of the blue light passing through the luminescent conversion layer from one side to another, such that the semiconductor component emits white light comprising the part of the blue light passing through the luminescent conversion layer and the light emitted in at least the portion of the second wavelength range.
