Connecting a single string of LEDs to an LED driver is the safest and surest method of driving LEDs. If any LED fails
causing an open circuit, the current to the remaining LEDs in the string is broken. If any LED gets short circuited, the
current in the remaining LEDs remains the same. Driving multiple strings from a single LED driver has the advantage
that more LEOs can be driven, but there are dangers of LEOs failing. With two strings in parallel, if any LED gets open
circuited, constant current will flow through the remaining LED string and causing its failure after a very short time. If
any LED gets short circuited, then the currents flowing in the strings will be unbalanced with the majority of the current
flowing through the string with the shorted LED, thus causing the failure. Different LED configurations are shown in figA.
