New “TEN°” binning from Osram Opto Semiconductors provides the basis for extreme color consistency for white LEDs that are used as single-LED light sources in lighting solutions such as spotlights and downlights.
To achieve this, the current standard CIE 1931 2° xy color space has been supplemented with CIE 2015 10° u‘v‘, recently developed by the International Commission on Illumination and implemented by Osram Opto Semiconductors as 10° binning.
In contrast to the established CIE 1931 2° color space, the recently developed CIE 2015 10° corresponds more closely to the physiological perception of color. This subject is of particular interest for achieving uniform illumination from spotlights and downlights in which individual white CoB LEDs are primarily used.
This new binning will be used for the first time in the new generation of the Soleriq S 13. If Soleriq LEDs that have been binned on the basis of these latest findings are installed in spotlights, for example, it will be much easier to avoid differences in light colors compared with products grouped according to the old CIE 1931 2° standard. This in turn means fewer process stages for luminaire manufacturers that would otherwise be necessary because of different white color impressions in the ultimate application.
