### White LED

I had gotten a bit frustrated trying mimic with appearance of white LEDs by smushing gaussian textures and RGB values together, so with some help from http://en.wikipedia.org/wiki/File:White_LED.png and LordCrc, I put together a little tabulated data file for it. Copy and paste this into a text file and load it up in the tabulated data texture, and set that texture as your emission color. Enjoy.

Code: Select all
Emission spectra of a typical "white" (GaN + Ce:YAG) LED. Reconstructed from http://en.wikipedia.org/wiki/File:White_LED.pngIntensity is relative, it is effectively a direct lamp color value.wavelength: nmlambda    intensity (nm)       (relative gain)   300 0.0350 0.0400 0.0425 0.4460 3.7500 1.0550 1.9575 1.8600 1.6650 0.6700 0.35725 0.2750 0.0800 0.0
