CIE LED Illuminant Tables Follow

Nine new Illuminant/Observer tables have been added to EasyMatchQC, these represent the LED Standard illuminants published by the CIE at the end of 2018.   These are not designed to represent any specific manufacturers commercially available White LED, instead they are designed around the typical CCT (Correlated Color Temperature) of a class of available LEDs. 

These nine new LED illuminants are listed below, a reference to their CCT is given so the user may select one that is similar to the LED’s under which the observer would be viewing the specimen.

          CCT (CIE 15:2018)

1. LED-B1           2733
2. LED-B2           2998
3. LED-B3           4103
4. LED-B4           5109
5. LED-B5           6598
6. LED-BH1        2851
7. LED-RGB1      2840
8. LED-V1           2724
9. LED-V2           4070

B1-B5 are typical blue excited phosphor type LEDs with different CCTs.

Bh1 is a hybrid type with added red.

RGB1 is a tri-led source

V1 and V2 are violet enhanced blue excited phosphor LEDs
