The resistor / LED array would be useful as reliable and
long lasting lights as always on and independent emergency
exit illumination for buildings. It should be respected
for that. I think the design needs to be improved to
compete with the diode array. It may simplify to
transparent metal oxide nanosphere LED anodes or cathodes
on a special semiconductor substrate forming billions of
nanometer scale LEDs in parallel feeding a high resistance
load which does translate to an extremely high resistance
load for each nanosphere LED. The rationale is that when
the Johnson noise goes forward in one LED the array is
loaded down to the optimal current and voltage point by
the other 50% of the LEDs as all share the control
resistor which can not impart extra noise. The higher
forward voltage and much higher reverse voltage involved
dictates a greater nanosphere LED spacing than nanopost
diode array anodes need. The devices may be competitive in
light panel applications.
