after turn off the switch, LED lights still on. This phenomenon occurs mainly in large-scale LED chip, because aluminum substrate dozens or even hundreds of small LED beads. Led lamps and lanterns of each lamp voltage is about 3 v. Manufacturers are considered in the design the production process and cost issues, after simple resistance will be a massive LED bead into mass production. Circuit in series, the general use of the wall switch are single-stage single throw, namely after turn off the lights, fire lines cut, the zero line connection.

however, the potential energy is zero, zero line and the line of fire and the earth or grounding structure is different. Part of the inductive voltage of the power cord is very long, only a few volts, but the current is very small, so don't feel at all. But it is enough to make small current faint light LED bulbs.

to solve this problem, we should start from the following several aspects. First of all, will be the main power cord zero line to the line of fire. If not, please follow the following methods. Converts all switch control LED lights to bipolar single throw switch. Lamps and lanterns power 220 v parallel imports - 470 k 1 m discharge resistance. In general, these problems can be solved in these ways.

in fact, LED lamps and lanterns is common in lighting or closed after, if you can adapt to it, it wouldn't have it, after all these problems will not affect the service life of lamps and lanterns.
