LED imhando ye semiconductor iyo inoburitsa chiedza kana iwe uchipa iyo imwe voltage.Iyo nzira yekugadzira mwenje ingangoita fluorescent rambi uye gasi rekuburitsa rambi.LED haina filament, uye chiedza chayo hachigadziriswi nekupisa kwefilament, kureva kuti, haibudisi chiedza nekubvumira ikozvino kuyerera kuburikidza nemagetsi maviri.LED inoburitsa masaisai emagetsi (akanyanya kuwanda kwazvo ekudengenyeka), kana masaisai aya asvika pamusoro pe380nm uye pasi pe780nm, kureba kwemasaisai epakati kunoonekwa chiedza, chiedza chinooneka chinogona kuonekwa nemaziso evanhu.

Chiedza-emitting diode chinogona zvakare kukamurwa kuita akajairwa monochrome light-emitting diodes, high-brightness light-emitting diodes, Ultra-high kupenya chiedza-emitting diodes, color-kuchinja-light-emitting diodes, flashing light-emitting diodes, voltage-controlled. light-emitting diodes, infrared light-emitting diodes uye negative resistance light-emitting diodes.

application:

1. AC simba chiratidzo

Chero bedzi dunhu rakabatana kune 220V / 50Hz AC magetsi emagetsi, iyo LED ichavhenekerwa, zvichiratidza kuti simba riripo.Iko kukosha kwekupokana kweiyo ikozvino inomisa resistor R ndeye 220V/IF.

2. AC chinja chiratidzo chiedza

Shandisa LED sedunhu re incandescent mwenje switch chiratidzo mwenje.Kana switch yadzimwa uye girobhu remwenje rabuda, ikozvino inoumba loop kuburikidza neR, LED uye mwenje girobhu EL, uye iyo LED inovhenekera kumusoro, izvo zviri nyore kuti vanhu vawane switch murima.Panguva ino, ikozvino muchiuno idiki kwazvo, uye girobhu remwenje harizovheneke.Kana switch ikabatidzwa, girobhu rinovhurwa uye LED inodzimwa.

3. AC simba socket chiratidzo chiedza

Dunhu rinoshandisa maviri-mavara (common cathode) LED sechiratidzo chechiedza che AC outlet.Simba rekushandisa kune socket rinodzorwa nekushandura S. Kana iyo tsvuku LED iripo, socket haina simba;kana LED yakasvibirira iripo, socket ine simba.
