Need to solve the problem of the LED light flashing
Problem in the connection on the way, I guess you're mistaking 40 simple lamp bead is divided into 10 road, every 4 star all the way, so directly in parallel on the 12 v is? First answer me how do you connect again to teach you.
Confirm your 12 v charger ac components have? Using the multimeter, exchange files have measure ac voltage, and you want to confirm what you said is the lamp bead board was flashing (that is specialized flashing LED lights with IC control board).
What is your charger charger? Is the core or electronic transformer? Is ac or dc? Estimate your output power is communication, not after rectification, etc.
Don't listen to their blather. I am happy for the hangzhou hong yan electric appliances co., LTD., prevent myopia LED desk lamp, use for two months, flash, happy to buy in the new, two months, crossed and sent to the factory repair, two months later, crossed over the warranty period now, happy to buy, no matter the also don't do this kind of desk lamp, can't, looking at that - all LED flash small, how to also won't be bad, so please people in a dc power supply, not 12 v, so we have to use the 9 v dc power supply, it's no use router didn't effect, good, don't flash at all. This could be a blind cat touch dead mouse, solved the problems of inductance.
