Hello and greetings from finland!
I ordered long time a go a 72w, 24 High Power Led Bar that can be used from 10 ish volts to 30 volts.
recently the leds stopped working and now theres just 6/24 left that lights up. I opened it up and found out that it was cheapely made with slim components and no capacitors.. The leds were connected in series so the power draw was 9watts for the 3 leds and the controller was a 6 pin chip with "PT4115 12962C", just of 2 of therse little guys were alive of a total of 8. Some of them was blown off the board and left a hole and some of them were melted.
Now i did some research and found out that they are indeed poorly made but i still want it working again. I found that LM317 could be used to power 1 of therse leds but sence they are connected 3 in series that was not the best idea, because of the cost and so on. I found some "Led Drivers" on ebay that was rated for 1x3w,2x3w and 3x3w leds but they seemed to be built the same way the original was but without the capasitor. there was so much different ones with different "specs" but all looked the same. here was the one i found. http://www.ebay.com/itm/5pcs-LED-Hi...ing_Parts_and_Accessories&hash=item3cd65590af
Does anyone have a idea how i could power therse leds again without spending so much Euros on expensive drivers. If you know please let me know. Pictures are bellow.
Pictures will be uploaded in a few Minutes.
