Hii
I am looking for suitable LED driver for my application. 70% of LED bulb, led gets damaged and if one led is damaged (as all led's are connected in series) no more light even if remaining are fine . For ex if 12 leds are arranged in 3 strings each of 4 leds in series all-together connected in parallel. So if one led gets damaged remaining two string are active. So i need a constant voltage(CV) led driver bcus constant current is not feasible for this purpose. 220v AC input, 15V output voltage, 5-15Watt output power. Any other useful advises are welcome.
