One meter band of LED lights. Let me cut it in the middle. Then I found a thread and put it together. Why didn't it turn on?.
The copper sheet inside is actually a flexible circuit board with copper foil wires on it, and the wires of these copper foil should be connected.Do you want to open the plastic pulling off a short, then use sandpaper or knife white copper foil surface insulating layer off exposed copper foil, see a few roots in the position for welding.
Then the outside two main lines also need welding.Be sure to wrap it with insulating tape. Don't short-circuit it with the outside. The outside is 220V high voltage.
