[PSUBS-MAILIST] 10K LED Light project - Housing

[Alan James via Personal_Submersibles]

Cliff,you mentioned doing thermal calculations. I found this good article on Wiki that may be helpful.https://en.wikipedia.org/wiki/Thermal_management_of_high-power_LEDs
If the heat output is a big problem we can always turn the current down.I believe running a 10,000 lm LED at 5000 lm is a lot cooler than running a 5000 lm LED.This is something we could look in to more if we get in to trouble. I was still getting a lot of light offmy 50W LED & keeping it cool by running it on low amps.Alan

Alec there is a small 2 pin wiring connector called a Pico EZMATE connector that has a two wire pigtail that plugs into the  array. See Digikey part number WM9591-ND.  The pigtail is inserted into the hole in the slot to enable wires to be connected to the PWB on the inside cavity of the back of the housing.  I need to add a drawing of the part but have not been able to find a 3-D of the part online.

Wow!!!! That is really amazing. It looks totally buildable and I love the provided part numbers for the components. One question Cliff... what is the purpose of the groove shown in Detail D of the LED-01 drawing? It looks like it's meant for positioning a tab or something, but I can't see anything fitting into it.
Thanks,

Alec

PSUBS.ORG -> PSUBS Community -> Community Projects

Not sure why it won't upload to the webforum so I have put it in 
temporary space (see above).  Make sure to "refresh" your browser so you 
can see the new link "Community Projects" in the main menu.
