Re: Phosphor conversion of photons in LEDs
I remember reading exactly what you just said here about stainless steel. It's a completely valid point that demonstrates albedo might be high but the important components of the light getting absorbed by the reflector render the albedo by itself misleading.
What is the ratio on blue photons to yellow photons in the white light headed to the wavien collar?
Photon in the German forum tried selfmade stainless steel collars a few years ago. They worked, but not very good. Why? Because stainless steel only reflects around 30% of 450nm light. Low gain wa salso caused by the larger hole on the top, by the fact that he polished them instead of putting on a real coating, and imperfect shape, small collar size, sub-optimal led tint, maybe imperfect focus etc..
