chuckstyl5 Posted February 22, 2010 Share Posted February 22, 2010 Well I got my heatsinks today -- 20" long .... Did a quick cleaning and polished them up then removed the oil/grease and now just waiting for the thermal pads and the rest of the LEDs there are before and after cleaning pics Link to comment
chuckstyl5 Posted February 26, 2010 Author Share Posted February 26, 2010 here are some more pics of the heatsink with the thermal pads and LEDs --- just waiting until I recieve the rest of them Link to comment
chuckstyl5 Posted March 2, 2010 Author Share Posted March 2, 2010 well here are 1/3 of them wired up and almost ready to go Link to comment
mike30g Posted March 2, 2010 Share Posted March 2, 2010 this might be a dumb q but what is the purpuse of the heatsink on a led? i thought led did not give of that much heat. like i said i dont know much about the led setups so if this is stupid please let me know else wise. mike Link to comment
phalanx Posted March 2, 2010 Share Posted March 2, 2010 this might be a dumb q but what is the purpuse of the heatsink on a led? i thought led did not give of that much heat. like i said i dont know much about the led setups so if this is stupid please let me know else wise.mike The semiconductor used inside of an LED is fairly temperature sensitive. If it is overheated, it can easily fail. Modern power LEDs are typically run at 3-5 Watts of power. Since the die in the LED is small, the relatively small amount of power being dissipated can quickly raise its temperature to a point where it will fail. The heatsink takes the concentrated heat source from the LED and spreads it out over a much larger area so it can be radiated off in open air. This keeps the LED cool and prolongs its life.

chuckstyl5 Posted March 12, 2010 Author Share Posted March 12, 2010 here is the newest update pic --- THE FIXTURE!!!!it works PERFECTLY!!! Link to comment
widebody Posted March 12, 2010 Share Posted March 12, 2010 nice set up when are you planning to fire it up ...what fixture did you use here is the newest update pic --- THE FIXTURE!!!!it works PERFECTLY!!! Link to comment
chuckstyl5 Posted March 12, 2010 Author Share Posted March 12, 2010 hoping i can turn it on this weekend --- the only thing im missing is the reefkeeper but i will figure something out --- its from catalinaaquarium.com Link to comment
widebody Posted March 13, 2010 Share Posted March 13, 2010 so your heatsinks are 7x 20 Link to comment
chuckstyl5 Posted March 13, 2010 Author Share Posted March 13, 2010 yea and they slid right into the fixture - its a perfect fit Link to comment
chuckstyl5 Posted March 15, 2010 Author Share Posted March 15, 2010 well things are wrapping up and coming to an end -- a couple more adjustments and connectors and it will be all done Link to comment
wfournier Posted March 15, 2010 Share Posted March 15, 2010 What gage wire did you use to hook up the LEDs? It looks HUGE, I might be a little worried about that... Link to comment
evilc66 Posted March 15, 2010 Share Posted March 15, 2010 Nah. Looks fine. Good solder job too. Link to comment
bruce922 Posted March 15, 2010 Share Posted March 15, 2010 Your much more handy than I am. I really like your build! Link to comment
chuckstyl5 Posted March 15, 2010 Author Share Posted March 15, 2010 well after i wired every single LED - 60 in total ... I kinda realized i could of went smaller -- I used 18 gauge and then the power wires were 22 gauge ... i really didnt want to re-wire the whole thing and i also hope it wont make a difference in the fixture ---- in the grey box you see is all the pos and neg array wires attached to a d-sub connector and then a svga cable from there to the "power house" all the drivers ... it will be attached to a reefkeeper to control everything .... quick question do the meanwell drivers give off a lot of heat??? cause if they do i might have to change things around Link to comment
evilc66 Posted March 15, 2010 Share Posted March 15, 2010 They get warm. I would ventilate that box, and/or go bigger. Link to comment
chuckstyl5 Posted March 15, 2010 Author Share Posted March 15, 2010 thanks evil! thats exactly what i needed to know Link to comment
chuckstyl5 Posted March 16, 2010 Author Share Posted March 16, 2010 here are the final pictures.... Link to comment
widebody Posted March 16, 2010 Share Posted March 16, 2010 did you mount any fans to this ..where did you hide your drivers ..looks great Link to comment
chuckstyl5 Posted March 16, 2010 Author Share Posted March 16, 2010 fans are on the way --- i will have 2 40mm fans on the endcaps of the fixture blowing air thru it .. if you look at the first pic in the bottom right hand corner you can see a box .... that is where all the drivers are --- i have only one wire that runs from the fixture to the box that holds the drivers Link to comment
jtl2 Posted March 16, 2010 Share Posted March 16, 2010 Splashguard? Couldn't tell from the photos. Nice job. Looks great! Link to comment
mcclandy Posted March 16, 2010 Share Posted March 16, 2010 are you happy with the thermal pads vs. srewing and thermal pasteing the LEDs? And do you feel that the number of LEDs is sufficient for SPS or clams? Link to comment
