Hi friends,
The LED lamp illumination is is the ultimate monitoring paramaeter
for any LED failure in a lamp. This is the prefered system in railway
signal meant LED lamps.

Any one of you can describe on how to monitor an LED lamp
illumination. Is photo sensors can do the job! What is LDR. Also can
you suggest best connecting matrix of the LEDs which gives an
effective operation.
