Osram LUW CEUP* headlight LEDs

Osram lists 2 new headlight LEDs, LUW CEUP.HD and LUW CEUP.CE

  • 3000K and 2200K respectively
  • ~1mm² die
  • 1.5A max current
  • small package without DTP, won’t beat any throw records

Still low CRI, but I view this as a bit of refresher after the string of cool-only emitters.

EDIT:
Djozz corrected me, these are cool white and uninteresting. :frowning:

Lets hope lower CCTs catch on in the automotive world. I wonder if these are intended for fog lights though.

WHO NAMES THESE THINGS! :smiley:

Both links from the OP seem to go to very cool white emitters, what am I doing wrong?

Not sure. Let’s go with CEUP.CE. Does the link get you to the proper site?
When I download the datasheet, I see that colour is Cx = 0.33, Cy = 0.34.
I enter that in
http://www.brucelindbloom.com/index.html?ColorCalculator.html
and the result is 2934.4K.

Cx=0.33 Cy=0.34 gets me to 5600K

Dunno that calculator, does it include a CIE 1931 colour space calculator that is commonly used by the led manufacturers?

I took a different calculator which explicitly names CIE 1931:

This one shows ~5000K…So neither ~3000 nor ~5600. :person_facepalming:

that calculator gives me 5600K for Cx=0.33 Cy=0.34

Maybe it’s just my machine but the chart has shifted labels. Yes, it’s 5600K. :weary:
Thanks for correction djozz!
