req to clarify doubt about LED driver designing
Hi sir, i have interest to do LED street light of ac to dc using LDR(Light dependend resistor). but i dont know whether it is possible or not.. so kindly clarify my doubt. if it is possible please send me the detail of the circuit.
our specification needed by following
input: AC 150Vac- 240Vac
output DC 20-50Vdc ,350mA-1.2Amps

What is the purpose of the LDR?. If its a turn-off circuit, pls refer to the thread below

We dont have a fully tested Design example report yet using LDRs but you can see the above thread to give you an idea.
