I am trying to learn how to work out what LED driver to use and how to connect the LED's
I want to connect 50 LED's for example to a 12 Volt supply. The LED's have the following specifications
Vf = 2.2V
Vi = 25mA
In the past I would have used the LED calculator found at http://led.linear1.org/led.wiz
Using the above details This calcuator shows 5 LED's in Series with a 47 Ohm resistor and 10 of these arrays in Series.
I would like to be able to calculate this myself and in turn use a driver which from what I read is more suitable method.
Any assistance will be apprecieated.
