So I'm pulling apart one of the RGB LED strips supplied with my new NZXT Hue+ which was faulty out of the box. Using my multimeter I've managed to work out this much so far with it's wiring. It's been a while since my A-Level Electronics classes!

This diagram was just made using a multimeter touching from one component to the other and seeing how it linked up. As reverse engineering goes, I'm not at the standard of the Chinese yet.

I have a few questions though:

1) Does the diagram look right? I believe the rectangles I have drawn are actually diodes as there is a small voltage drop one way and none the other. Sorry the symbols are incorrect, but I ran my multi meter over them after I drew it and didn't feel like doing it again. And yes, I know that's not the symbol for an RGB LED!

2) How does the NZXT Hue+ control each LED individually? IF they are wired up in parallel, how does it say to LED 1 that it must be Blue yet LED 2 is Green?

3) There are a few tracks on the reverse of the LED strip which seem to run the full length but have dimples on them in sections, saying to me that the strip is using both sides to control it.

My aim is to rewire these LED's using wire not PCB tape to get them to fit a very specific section of my case. Am I going along the right path? I can't remember electronics but I'm still a dab hand with a soldering iron, so just need to work out it's wiring.

Thanks!
 
Thats a set of addressable LED's. They are controlled by the input signal (a carrier signal) which is sent down the entire chain.

In very simple terms, each led has a small chip in it that takes the input signal, removes the piece of data it needs from the input signal chain and then sends the data off to the next chip and so on.

To program them you need to write the entire chains worth of information in one go, then run a controller that can process that information, adjusting voltages on the fly to control the colour spectrum output of the LED.

The LED's only use the 4 input points on the chain. So long as those inputs/outputs all match up you should be good to go at chopping and moving them all. Bear in mind that the length will be determined by the controller the LED's came with. You can't just cut out 3 led's and use those as the input signal coding would need to be changed to reflect the new number of LED's.

Without seeing a picture the tracks on the back just sound like a neater way of running the power lines for the led's down the strip. Again, without seeing them the little dimples might just be the solder points that join the chain together. Most LED strips can be cut at certain sections without harming the led's in the chain. You can only cut at these points if you plan on removing the LED's from the chain altogether as they're usually linked in groups of 3-4 led's on the chain.

Ah fantastic Krisboats, thanks. It didn't occur to me that there may be a chip in each LED. So that layout above looks about right? I intend to keep the same amount of LEDs, just reduce the distance between them to fit them in a part of my case which, at the moment, is too small.

A small amount of 4 core wire should do the trick nicely. I may just cut each LED section and solder the PCB's rather than trying to solder surface mount components.

Excellent news for me then, thanks, I knew it'd be simple enough, just couldn't get it to click.
