Method of the binning of a radiation emitting optoelectronic semiconductor device comprising the steps of: - providing a radiation emitting optoelectronic semiconductor device , - determining the color locus of the light emitted by the radiation-emitting optoelectronic semiconductor device during operation, - classifying the radiation-emitting optoelectronic semiconductor component into a predetermined color locus range , which comprises the determined color locus, wherein - the predetermined color locus range is selected from a group of color locus ranges and at least one of the color locus ranges from the group of color locus ranges comprises a blue color locus and/or comprises a color locus to which no correlated color temperature can be assigned, wherein - at least one of the color locus ranges from the group of color locus ranges is intersected by an extended Planck curve or adjoins the extended Planck curve , which continues the Planck curve at its high temperature end point (Tu) and forms a composite curve with the Planck curve , - the extended Planck curve continues the Planck curve at its high temperature end point (Tu) in an at least once continuously differentiable manner, - an address is assigned to each color locus range from the group of color locus ranges, - the address has a first parameter (p) indicating the distance of the color locus range along the composite curve from the high temperature end point (Tu) of the Planck curve , - the address has a second parameter (j) indicating the distance of the color locus range from the composite curve along a Judd line , and - the size of each color locus range from the group of color locus ranges is selected such that an observer perceives no difference for colors from the same color locus range. - providing a radiation emitting optoelectronic semiconductor device , - determining the color locus of the light emitted by the radiation-emitting optoelectronic semiconductor device during operation, - classifying the radiation-emitting optoelectronic semiconductor component into a predetermined color locus range , which comprises the determined color locus, wherein - the predetermined color locus range is selected from a group of color locus ranges and at least one of the color locus ranges from the group of color locus ranges comprises a blue color locus and/or comprises a color locus to which no correlated color temperature can be assigned, wherein - at least one of the color locus ranges from the group of color locus ranges is intersected by an extended Planck curve or adjoins the extended Planck curve , which continues the Planck curve at its high temperature end point (Tu) and forms a composite curve with the Planck curve , - the extended Planck curve continues the Planck curve at its high temperature end point (Tu) in an at least once continuously differentiable manner, - an address is assigned to each color locus range from the group of color locus ranges, - the address has a first parameter (p) indicating the distance of the color locus range along the composite curve from the high temperature end point (Tu) of the Planck curve , - the address has a second parameter (j) indicating the distance of the color locus range from the composite curve along a Judd line , and - the size of each color locus range from the group of color locus ranges is selected such that an observer perceives no difference for colors from the same color locus range. <EOS>
