Hello all, this is my first post here and I hope to get some help. I have a pre-built LED fixture from Build My LED. Recently part of the fixture went out, so I am not getting full use of the ridiculously expensive fixture (thankfully I am not the one who purchased this or I would be pissed). Anyways I took the fixture apart in hopes of being able to fix it.
From what I can tell, part of the fixture is set up in parallel and part is in series. A total of 48 inches long, in 12 inch sections, each section with 15 LEDs. Each sections LEDs are in series, but each section is connected together in parallel. The section that went out has one led on it that popped, and in turn seemingly took out the rest of the section, hence it being setup in series.
Hopefully I am making sense. So me being me, I soldered in a wire to replace the burnt out LED. This is obviously going to cause a problem, my understanding is now each LEDs voltage in this section is now higher. There are clearly some heat issues when I leave the fixture on for more than 30 seconds.
What do I need to do to fix the rampant heat issue? I imagine a resistor is a solution? How can I determine the type of resistor? I do not know the specs on each LED except for what is provided here Build My LED "Specs" which really isn't a whole lot.
I do have the power supply specifications:
Input voltage 100-277VAC 50/60Hz
Input current 0.9A @ 100VAC
Output voltage 27-54VDC
Output current 0.14-1.4A
Dimming voltage 1-10VDC
I am not running the dimmer, so its outputting at max specs. Help would make me and my fish tank occupants much happier, especially my corals
If there are any other bits of information that are needed to solve this problem that I might be able to provide, let me know and I will do what I can to get it.
