b regulator driver circuits to drive LED, each string needs to be coupled with an appropriate resistor so that each string of LED display brightness average;

c regulator circuit are not afraid of open load, but non-load completely shorted;

                                                                        

d When the parameters of the regulator circuit is determined, the output voltage is fixed, and the output current, but varies with the load change;

It should be noted that using a maximum withstand current and voltage values​​, which limits the use of LED quantity;

 

b led constant current driver circuit is an ideal, but the relatively higher prices;

 

c constant current circuit afraid load short, but non-load completely open;
