Compact 15 degree XR-E/7070? reflector... ???

Hi fellows, a tad bored as usual lately. Checking out eBay searching for XR-E lenses, as I presume they would also do good on 7070 emitters Question , just found this cute looking thingie:

10pcs 15° LED Reflector Collimator Lens Cup Base For Cree XR-E/XM-L/XM-L2 Q5 T6

Mmm, isn't it a tad fat opened for 5050s?

Well, would it pair nicely with quad-die emitters? Seems to have “texture” for it, right? It also has about the right height to be crowned with a 11mm focal distance aspheric, LoL!

Nice price. Smile


Cheers Party

And you better take care of your mind programming, or someone else will in this wicked world.

Very interesting idea indeed.  I don't like the idea of reflectors that step out like that.  Seems like there has to be a shadow cast after each step that wastes reflector surface.  With your multi-emitter idea, that might be a minimal impact.  Sure is low cost enough to try out.  Smile

15-20 degrees seems to be hotspot angle. Full angle is much bigger.
