Adressable LED connections and luminosity difficulties + portable design questions

Use "extra flexible" wire and progressive strain reliefs - eg. very stiff over the joints, then progressively more flexible further away, using thinner material or less layers etc.

If done properly, there should be no "kink" point when the wire flexes, it should form a smooth curve.

As long as the flexing sections are long enough so the bend radius is never too small, they should last years.

That's what i've been doing (silicone wires, heat shrink layers), but it seems it stills strains the board of the LED strip (despite the heatshrink around the extremity of the strip), and unsticks the conductor alltogether with the soldering, or breaks the cable inside the heat shrink...

Do you think it would be stronger to weld directly a connector header male (+ epoxy sticking eventually), then connect to it properly crimped cables ? Is there a way to crimp 2 cables together into a connector that goes to the header ?

Sorry about the noob questions, i have a good idea of WHAT i want to do, but i'm lacking experience on HOW to do it, so i'm maybe thinking of innefficient ways. Note: i plan to to repeat this project in the future (will try to sell it), so that's why i'm looking for the most reliable/repeatable solution i can find.

Thank you

If the wires will be under tension, rather than just flexing under their own weight, you need to add a cord that is mechanically attached at each end, to prevent the wires from being pulled.

If they are detaching while flexing under their own weight, then there is a definite problem with the soldering and physical strain relief.
