As Osram has released, its new “TEN°” binning provides an “unprecedented” color consistency for white LEDs which are used for example as single-LED light sources in spotlights and downlights. Osram has replaced the current standard CIE 1931 2° xy color space with CIE 2015 10° u‘v‘ as recently developed by the International Commission on Illumination and now implemented by Osram Opto Semiconductors as 10° binning. “TEN°“ will be available on the market as an additional feature from March 2016 within third generation of Soleriq S 13


“TEN°“ is the name of the new white binning technology of Osram which corresponds much better to the physiological perception of color. Uniform illumination can be achieved from e.g. spotlights and downlights in which individual white COB LEDs are primarily used. The new binning will be used for the
 
Osram has developed this new technology, because so far two LEDs with the exact same color coordinates in the CIE 1931 2° color space could still render noticeably different white tones. One reason is that the small rods that are responsible for color perception in our eyes are not evenly distributed. which leads to different color perceptions even with LEDs in 1 SDCM binning with conventional metrics. Osram’s new “TEN” technology has provided a solution to this problem.
