At least 50 times a day, someone will tell me “We lack efficient, high output, high CRI mules”. Well this is it, the voices in my head have won. I have dubbed it “Phobos”.
It does get pretty toasty, real quick on turbo. Will the 3D printed ring hold? We’ll find out.
The “mule spacer” are multiple demasked copper MCPCB’s, soldered together. These also function as a bit of extra heatsinking. I used solid copper wire as centering dowels.
Looks good! Those quad boards have been around for years but I’ve not seen many builds with them, I put one with 4x 519s in a convoy L6 with a shorty tube and driver from Hank. The beam is a bit doughnutty and I need to tidy up the soldering.
Yeah, this quad 6v mule has been on the list for a while. And that L6 sounds like a real frankenlight! Got any pics?
Yes it is, @Hoop . It was the simplest option to hide the ugly generic “CREE” board and double as a spacer.
The design definitely needs some refining, but initially I I wasn’t sure if it was going to hold up to the temperature. Looks fine for now. Will add some new variants soon.
I have added them in the OP.
I find it very peachy of colour and it even holds its own when compared to the 219B mix. I will try to get a green AR coated lens, as the purple ones are detrimental to -DUV.
I am desperately looking for a “normal” 20mm 2S2P 3535 for TIR optics… I think it doesn’t exist, and will have to design my own.
Do you mean an optic for that tight 2x2 configuration? I don’t believe I’ve seen anything like that. I think the LEDs are too close for four individual TIRs like a more “normal” quad optic.
Like @Quadrupel said, printing that neat spacer/gasket/reflector thing in white could give it some additional throw, if that’s what you’re looking for.
If I’ve got some time when I’m next back in November, I’ll redo the solder and take pics at the same time.
Also have a FC40 led I want to try. The driver is a tad low powered for these LEDs, I will have to see if there’s a component I can change to give more output.
