Also don't forget that AC is usually given as an RMS value so the peak voltage is 1.414 times that. I recommend another diode across it connected in reverse to shunt the backward voltage. The BEST thing is to just connect another LED in reverse across it. That way you do get light emitted on both half cycles. もっと見る
