LED ndi mtundu wa semiconductor yomwe imatulutsa kuwala mukaipatsa magetsi.Njira yake yopangira kuwala ndi pafupifupi nyali ya fulorosenti ndi nyali yotulutsa mpweya.LED ilibe filament, ndipo kuwala kwake sikumapangidwa ndi kutentha kwa filament, ndiko kuti, sikumapanga kuwala mwa kulola kuti pakali pano kudutsa muzitsulo ziwirizo.LED imatulutsa mafunde a electromagnetic (kuthamanga kwambiri kwafupipafupi), mafundewa akafika pamwamba pa 380nm ndi pansi pa 780nm, kutalika kwapakati pakatikati kumakhala kuwala kowoneka, kuwala kowoneka komwe kungawonedwe ndi maso a anthu.

Ma diode otulutsa kuwala amathanso kugawidwa kukhala ma diode wamba otulutsa kuwala kwa monochrome, ma diode owala kwambiri, kuwala kopitilira muyeso, ma diode osintha mitundu, ma diode otulutsa kuwala, magetsi owongolera ma diode otulutsa kuwala, ma diodi otulutsa kuwala kwa infrared komanso ma diodi oletsa kuwala.

ntchito:

1. Chizindikiro cha mphamvu ya AC

Malingana ngati dera likugwirizanitsidwa ndi 220V / 50Hz AC magetsi opangira magetsi, LED idzayatsa, kusonyeza kuti mphamvuyo yayatsidwa.Mtengo wotsutsa waposachedwa wotsutsa R ndi 220V/IF.

2. AC kusintha chizindikiro kuwala

Gwiritsani ntchito nyali za LED ngati chozungulira cha nyali zosinthira ma incandescent.Chosinthiracho chikalumikizidwa ndipo babu yamagetsi imatuluka, magetsi apano akupanga chipika kudzera pa R, LED ndi babu EL, ndipo nyali ya LED imayatsa, zomwe ndi zabwino kuti anthu apeze chosinthira mumdima.Panthawiyi, magetsi omwe ali mu chipikacho ndi ochepa kwambiri, ndipo babu yamagetsi sidzayatsa.Chophimbacho chikatsegulidwa, babu imatsegulidwa ndipo LED imazimitsidwa.

3. AC mphamvu socket chizindikiro kuwala

Dera lomwe limagwiritsa ntchito ma LED amitundu iwiri (wamba cathode) ngati chowunikira cha AC.Mphamvu yamagetsi pazitsulo imayendetsedwa ndi kusintha S. Pamene LED yofiira ili, socket ilibe mphamvu;pamene LED yobiriwira ili, socket imakhala ndi mphamvu.
