AI Sol diode replacement anyone

Has anyone been able to replace an led diode on an AI sol blue . Since warranty is way up and they donít sell the pucks anymore figured I would see if it is possible to replace the diode myself . Any information would be great

cast iron skillet reflow might work for you, then pick the diode off with tweezers, and place the new one on.

It's definitely possible, it's more a question of your skills, tools, and how much effort you want to spend.

That would be my approach, assuming you can get a loose diode that's appropriate.

Or swap the whole star for another used one, since they're not available new. Keep an eye on eBay, sol parts come up once in a while, or sometimes units with multiple dead LEDs. If you're planning on running yours for a while, it might make sense to have a spare unit as a parts source.

The course of disassembling the AI Sol and examining the individual "pucks" that each LED group resides on, it became clear that the easiest way to proceed was to stay with Cree XP LEDs as much as possible. The LEDs on the pucks are all bare Cree LEDs flow-soldered directly to the puck, so I needed to find a place to source these LEDs. Ultimately I wound up purchasing the replacement LEDs from Mouser Electronics (www.mouser.com).
More advanced..

Funny thing is, that would be even easier with thermal tape and solderless 3-ups from LED g r o u p b u y. Could easily do up a suitable replacement for a single puck.

I like "creative" solutions..



Not to mention, rough calculation, you can add 3 3W diodes per channel...

36V (2A) power supply w/ roughly using 3x8V = 24..

A proper hot air gun (nice selection of nozzles) is usually the best tool for individual surface mount component replacement and you can pick them up for under $100..
