    • A conversion component for arrangement downstream at a radiation-outcoupling face of a radiation-emitting semiconductor chip is specified. The component has a converter element with a first major face, a second major face opposite the first major face and at least one side face. The side face connects together the two major faces. The converter element contains at least one luminescence conversion material, which is suitable for absorbing electromagnetic radiation of one wavelength range and for re-emitting the absorbed electromagnetic radiation in another wavelength range with larger wavelengths than the absorbed radiation. A reflective coating is designed to reflect electromagnetic radiation exiting from the converter element and to reflect it at least in part back into the converter element. The reflective coating covers the converter element at least in places at the at least one side face.
    • 规定了用于在辐射发射半导体芯片的辐射输出耦合面处布置在下游的转换部件。 该部件具有转换器元件,其具有第一主面,与第一主面相对的第二主面和至少一个侧面。 侧面将两个主要面连接在一起。 转换器元件包含至少一种发光转换材料,其适于吸收一个波长范围的电磁辐射,并且用于在具有比吸收的辐射更大的波长的另一波长范围内重新发射吸收的电磁辐射。 反射涂层被设计成反射从转换器元件出射的电磁辐射并且至少部分地将其反射回转换器元件。 反射涂层至少在至少一个侧面的位置覆盖转换器元件。
