XHP70 crude test

HugeOne · Mar 9, 2015

I got a XHP70 N2 bin ad made some quick testing. (In 6V configuration)

-Soldered the heat pad to 1/8 square copper tube.
-Built a crude lux meter with a LLS-05A linear light sensor
-Ran the test with icy water cooling.

Here's the data:

The 1/8 copper tube is a bit narrow for the heat pad, next, I will solder the LED on three 1/8" tube side to side so the + and - pads are sinking heat as well.

Looks good to 5 amps.
but if you need a burst capability, then 7.5 amps is nice.

Made a better heat-sink:

And the results:

Pushed the LED to 10A, the heat-sink topped at 32C and Vf was 7.28V

Theses preliminary tests look good for my next project:

Thanks for sharing the results.

It's always great to see what you come up with.

I haven't heard of too many other compact 140,000 lumen LED light setups latey.:twothumbs

Looking forward to seeing more progress on this project.

Pretty cool. How are you going to power that array?

Might be using dielectric fluid so that the pipes themselves are the conductors.

I modify a 6S lipo 80A brushed speed controller.

Yes, deionized water.

Any updates?

Project was on hold for the flying season but recently looked back in it. I purchased some graphite thermal interface material to even the heat of the tubes and attach a heat-sink to the whole thing.
Need to buy 24 XHP70 which not cheap.
