Hi all,
Just joined so hope this is done correctly.
I think this is the place that could answer my query.
I came across a simple piece of equipment that seems to have a redundancy. It's a backlight for an eye chart.
As pictured, it's a very simple design that consists of two 12V LED strips each of 8 segments and powered by a standard 12V PSU.
The PSU had failed but as I was inspecting the unit as a whole I noticed the links on both ends of the strip.
According to the technical file, "links are added top and bottom to stabalise voltage" .
I can understand preferring to link the bottom of the strips rather than the top so that the power source is effectively connected to 8 sections either side but to me, the top link looks completely redundant and unnecessary (I doubt it would be much of an issue if the only link was at the top to be honest as these are designed to run several metres).
My argument is that if the strip were one long section of 16 segments and you connected the power to the centre of the strip, it would look silly if you then ran a link from one end to the other and this is what is happening here.
Is anyone able to add their thoughts to this?
Always willing to learn.
