LED strip alignment
Posted: Fri Sep 03, 2021 6:40 pm
This question has two sides: On hand hand it´s about perception and on the other hand it´s about how madrix handles strip setups.
So I´ve built a small prototype for an LED ceiling, 16 strips, 5m each, 30 pixel/m, via 2 nebula. All strips run in parallel which means pixel pitch of ca. 3cm on one axis and 15cm on the other (strips are 15cm apart). That´s about half the hardware I have sitting here, so I will add 16 more strips. But what about their placement....
A) Additional strips in parallel to the existing -> pixel pitch will be 3cm on X, 7.5cm on Y axis. It´s still ca 1:2 difference.
B) Additional strips in right angle to the existing -> grid of 3cm pitched lines for X and Y axis, distance between lines is 15cm.
Option A is more like a traditional LED panel or LCD monitor, Option B is what is shown in a madrix showreel at 50 Club Kiev https://youtu.be/GDOFjqm7GE8 - just with a much larger distance between strips (in a much larger room... mine is just 4x5m).
What would you prefer in relation to perception, aka: What will look better?
If option B: How does madrix handle the crosspoints? Let´s say they cross LED on LED, will both LED´s get
a) half the illumation value
b) identical DMX data (so "crossing pixels" may be brighter)
c) full illumination for vertical and zero illumination for horizontal strips?
