I need to drive 40 x RGB LEDs spaced at 25cm intervals over a distance of 10mts.
Initial thoughts are to make a small PCB for each LED and use 3 Infineon BCR401R constant current LED drivers for each to ensure even brightness along the cable run.
Hook-up wire for daisy chaining the PCBs will probably be solid AWG24. Space is quite tight - the PCBs need to fit in a channel which is only10mm wide.
The LEDs will be driven in PWM mode (for colour mixing) using a micro and NPN bipolar/P channel FET switching the high side of 5, 9V or 12V.
Any suggestions or "gotchas" please?
