My 12WLED floor lamp, re demolition, and then installed once, how can not light problems?
The landlord is using low voltage lamp LED, the interior should be used to drive power supply with 220V AC into DC power supply for household use of appropriate beads.
The driver access LED bulb part is positive and negative, according to the landlord said, there may be the reverse lead does not shine here.It is driven into the lamp socket part, and the positive and negative electrode circuit is generally red positive electrode and black negative electrode.
It might be a bad connection, so it's hard to say, look at the picture
If you break it, you may not get it right
