I am planning to use readily available LED driver to drive these LED's.
As per my requirement;
I want to use 40LED’s. 4 strings of 10 LED’s.
As per calculation;
o/p W = 365 watts, o/p V = 350 volts, o/p A = 1.04 amps
Now my queries is;
1) Which type of LED driver do I select; Constant Current or Constant Voltage? I am using 4 strings in parallel in which each string has 10 LED connected in series.
2) If I opt for Constant Current LED driver then I have to use current control resistor in each string?
3) As we know 365W LED driver is very hard to get in market, can i opt to go parallel connection of LED driver? i.e. 180W parallel 180W.
Parallel Connection diagram is in attached file.
