The Canon LIDe 20 (and some other scanners) use three light emitting diodes (one each red, green and blue) that results in a light spectrum that is very close to sun light.

Actually I don't believe that. LEDs are basically know to be narrow-band light sources, so I'm wondering, whether the LIDEs actually capture the full spectrum w/o holes. Anyway - only the result counts ...
