I think I am going to fulfil a long time dream and build a MC-E RGBW light. First tests indicate that 2kHz software-PWM with a NANJG may be possible (each die driven by 2 AMC7135s).
But for that light I need a suitable host, I would like a compact 1*18650 host, able to hold a MC-E (20mm star), with a heavy OP reflector, all as small as possible, ~30mm head diameter would be nice. Does anyone know such a host?
I have always wanted to use that emitter so I hope you post your work when you do it. As far as host recommendations, I don’t have any lights that use a 20mm star so I can’t really help there.
EDIT: how about this Loading...
P60 would be nice, but 20mm stars don’t fit… and the MCE is quite big and I need to connect 5 wires, so I need some space.
Maybe the pill of a T2 or a similar compact light can be trimmed to be flat, I have no lathe though.
Langcjl: That one is quite big… I’d like to have it smaller.
gcbryan: Sure I’m thinking of ramping through the rainbow, probably in 90 hue steps.
Yes, must be diffused, that’s why I thought of a heavy OP reflector.
Does anyone know of a frosted wide TIR suitable for MC-E?
It seems LEDIL has a lens well suited for that job, RGBX-MC-M, diameter 30.4mm (22.8 at LED end), 28.8m height. Any idea what host this might fit into?
The Carclo wide frosted doesn’t seen to mix the colors well.
NightCrawl: there are some pictures on the carclo site with beamshots; the 25mm frosted wide for MC-E shows RGBW shots, too. With the the 20mm it’s probably similar.
gcbryan: the problem with ‘milky’ is that it’s probably quite lossy, too. I’d like to find something with a good efficiency.
Langcjl: A bit too expensive. But looks interesting indeed somewhat steampunky.
Nice builds... :)
PIC asm, not my language unfortunately :)
Well, the hardware is assembled and works fine, the current firmware is actually intended for a quad white light, so it's modes are not that well suited for RGBW. I just need to find some time to do this... other projects somehow have gotten ahead of this one...
Heh I didn’t even look at the code >< ASM! That could spell trouble… or opportunity, or both…
Wow so your driver is practically a complete custom? Incredible…
I will continue to look forward to people’s builds.
One more link, this one a 25mm board
