    • A plurality of light-emitting diode light sources of the same kind are produced simultaneously. Each light source includes a light-emitting diode chip and a luminescence conversion element, which converts the wavelength of at least part of an electromagnetic radiation emitted by the light-emitting diode chip. In a first process, a layer composite with a light-emitting diode layer sequence applied to a carrier substrate is provided. The wafer is provided with trenches and then inserted into a cavity of a mold. A molding compound, which contains a luminescence conversion material, is driven in, so that the trenches are at least partly filled with the molding compound. The mold is then removed and the light-emitting diode light sources are separated from the layer composite. In a second process, instead of the layer composite, a plurality of light-emitting diode chips which are applied to a common carrier in a regular arrangement are provided.
    • 同时产生同一种类的多个发光二极管光源。 每个光源包括发光二极管芯片和发光转换元件,其转换由发光二极管芯片发射的电磁辐射的至少一部分的波长。 在第一种方法中,提供了一种施加到载体衬底的发光二极管层序列的层复合物。 晶片设置有沟槽,然后插入模具的空腔中。 包含发光转换材料的模塑料被驱入,使得沟槽至少部分地被模塑料填充。 然后去除模具,并且发光二极管光源与层复合物分离。 在第二过程中,提供以规则排列施加到公共载体的多个发光二极管芯片代替层复合物。
