[project] budget XP-*/Nichia module with up to 8 AMC7135 on a board

Here’s the scheme

and here’s the board itself

and here’s it working

~20mm diameter, 2mm thickness, two independent branches up to 4×7135 each

may be used… oh, well, may be used in small-size flashlights with no-room for full-size driver like this


in stationary lighting, in car lighting etc

Nice board for a pill-less flashlight, it does not have a direct to core thermal path, does it?

Yes, that looks good!

This board makes building a light from scratch a bit easier, no pill needed, just a ridge for the board to rest on does the job.

No not DD, its just the two banks of 7135’s, no mcu, two switches turning on/off the banks giving you two modes.

those might be good for those printed hosts…make little mule lights…or even retrofit those wimpy 9 LED light deals from the auto parts store

pommie, not two only, it may be up to three: for example, one 7135 or two 7135 or all three together

Sorry for the confusion, banks or branches, same thing to me :bigsmile:
“two independent branches up to 4×7135 each”, you said it best.
