DIY LEDs with Radion Pro G2 pucks?

_shorty_ said:
ya! science...

anyone have a good close-up pic of a G2 puck? Any I find aren't too great of quality, and I don't want to wait for the mail to start planning...

Also - anyone know where one can find SMD LEDs that would fit onto these pucks? Thinking of turning the G2 pucks into 'G2 Pros' - they look to be the same boards. I don't know what different formats of SMD LEDs exist to know what to really look for, though. Does each manufacturer have its own SMD format? or are they pretty standard?

*edit - so for example: I think I need some semiLED hyper violets, but Steve's are round with big tabs sticking out - I'd need little square ones for these pucks. So far I've not found a source for this format of semiLED brand LEDs.

The picture from their website zooms in pretty well. I can see a close up of the PCB pretty well. As fr as the diodes, I went on an online hunt a few months back looking for some but I'm not sure where all I looked. Normally, I make notes, but I didn't for that one. I think a lot of the ones I found were from China, though.

Try cutter electronics.

Do you have a reflow oven on hand or a make shift one? the SMDs can't easily be reflowed without potential damage to the other chips without an oven. possibly with a hot air gun and really low temp solder past.........

It would be far easier to just space a handful of violets out around your heatsinks........

Thanks Zacts - the more I research, the more I'm finding that your suggestion is probably best. The next thing I was going to ask is if it's okay to use a heat gun and solder paste on a pre-existing puck like this. Definitely don't want to damage the pre-existing LED joints. I guess you're suggesting one MIGHT be able to use a low temp paste to reduce risk of damaging the existing LED bonds?

I've gotten feedback from Steve's LED too that the smaller, square formfactor SMD UV LEDs (that would be needed for this application) have a MUCH shorter lifespan (of only 1000 hours!?!). This seems like it can't be true since ecotech is using semiLED UV LEDs... or maybe it's a price thing - those in a comparable price range are shorter lifespan and that maybe the price jumps up to get into longer lifespan LEDs. I've had trouble confirming any of this lifespan information so far. On the spec sheets I've seen on semiLEDs site, I don't see any lifespan/rating numbers. Maybe I don't know what I'm looking for on those sheets...? My next step was to call semiLED directly and try to get more information and thier recommendations.

Again, I think the most reasonable solution will be as you suggested and just add extra LEDs 'externally', but at this point, I'm pretty curious as to the feasability of modifying the pucks since they are already set up to accept those additional LEDs.
 
Yesterday, I bought a set of G2 pucks off the selling forum. Sometime next week I should be getting them. I have the heat sink, LDD's and the controller. After I get the pucks I'm going to try to source the molex connectors and make a harness. If everything goes good, I'll have a working fixture in a couple of weeks.
 
Of I remember correctly the one PeteStewardson did looks like it had JST-XH connectors. They aren't the same but should fit.
 
This is the g3 puck ImageUploadedByTapatalk1394490424.011459.jpg

If we can use this they are cheaper than the aurora and lumia.

Someone said they tried it and it worked. But I'm not good enough to do this :(
 
The connector IS NOT JST-XH like I thought. I have one and tried it and the pin spacing isn't the same.

Here's the G2 puck close up. Each color is a separate circuit.
4 x outermost left and right blanks (violets on other versions)
4 cool whites
4 royal blues
4 blues
2 red - the additional blank in center is on the red circuit.
2 green

Top three pins are for what I'm guessing to be a temperature circuit. Don't know if it's analogue or digital signal yet.

Well looked at it today, but that was about it. Pete did it, and posted on another site, I found the site and posted there asking what connector he used. Waiting to hear back. I just searched his user name and radion nano and it was the first link.
 
I received a pm from the seller of my pucks. He said they'll be in the mail Friday at the latest. If someone wants to post the length-width-height & pin dia. of the connector, I'll start looking when I have some free time.
 
Sure, lol. I looked around, but I am not very good as sizing those up. I am still waiting to hear what Pete did.
