LED ceiling lamp, thunder will burn it?
The LED and its drive circuit are made of electronic components, some of which can be damaged only by hand static electricity, and thunder is also possible.Lightning does not necessarily cause the same damage to all users of minefields. There are many reasons for the intrusion of lightning through the grid and the extent of its damage. This difference can also be justified if you confirm that it was due to thunder damage.
LED lights, like other lights, have no grounding, and there is no grounding.The so-called grounding is generally designed to use the electrical network input terminals, to prevent leakage of electrical appliances wounding. Some grounding purposes are designed to prevent electrical interference.The lightning protection design is special, but it can only play a protective role within the limited range of lightning intensity.
The so-called life appliance in lightning protection (such as fixed telephone), is actually in line connected between the 1 components (solid package with 2 pole, 2 pole inside the package separated by a very small gap, there is thunder into the first air gap discharge, power grid theory through protection circuit, a bit) in the lightning intensity, so the protective effect is limited. Other household appliances have lightning protection design, the principle is basically the same.
Burnt.Leakage protection switch normal, is produced by current flowing through the coil when the leakage magnetic field, electromagnetic induced protection action to cut off the circuit and electrical suffered lightning damage more often because of high voltage caused by lightning.Ordinary leakage protector even closed indoor fundamentally incapable of action, the city power switch into the household, when the voltage is high enough for a lightning invasion of the grid, still can switch between the electrode breakdown and air gap formation pathways, even in the indoor circuit on electric appliances and equipment (think of electrostatic cloud layer on the distance of ground objects so far, lightning can still breakdown discharge, you know how high the lightning voltage).So, the safest way to make lightning weather is to unplug all appliances that need not or may not be used for the time being.
