Does anybody know if a remote phosphor will emit more and more visible light as the amount of royal blue light from the emitter increases? (Cree XT_E royal blue emitter) Or is there a built in limit in the remote phosphor? Like perhaps only “so many” lumens per square inch/cm of phosphor area? In other words would an ET-E with 4 emitters as is done with the XHP’s, produce a proportionate increase over the standard single emitter ET-E?
Thanks.

and much more, from poking at ’oogle a bit. I’ve glanced through this and got a few pieces to play with but haven’t pushed into doing much with the stuff yet myself.
“www.ledsmagazine.com/…/remote-phosphor-technology-can-deliver-a-…With a remote-phosphor solution, by contrast, it is possible to use five blue LEDs at a hot ChromaLit conversion efficacy of 177.6 lm/W at 10.5W input power….”
I dont know if this helps to answer your question but I know one manufacturer uses the same size remote phosphor “housing” across their range with the only thing changing being the amount of leds on the board. The remote phosphor stays the same size also but the output range is from 700-5000 lumens by adding more royal blue leds.
Heat will probably be an issue before reaching any potential threshold in the phosphor.
Thanks for the comments… when I implement my idea I’ll post
