minimum radius bend with NeoPixel strips

by open_d on Thu Dec 02, 2021 3:47 pm

If I were to make small loops using Neopixel 60 or 144 LED strips, with the LEDs pointing out (to illuminate inside of a frosted, translucent ball), what's the tightest radius I could safely plan on using? The application is to light up 5" globes as snowballs, so I'm seeking a product and geometry that will yield roughly even luminance, but perfection isn't necessary. I'm guessing 2 rings oriented 90 degrees apart would suffice. Or, is there a better solution? Rings and jewels seem like they'd leave strong shadows.

I'd probably go with 6 jewels in an outward-facing cube configuration.

Or maybe 4 jewels or SmartPixels in a pyramid form. Sharp bends put a lot of stress on the solder joints. This is even more of problem with the high-density strips since the pixel chips don't flex and there is not a lot of flexible backer between the pixels.
