LED ni ubwoko bwa semiconductor itanga urumuri iyo uhaye voltage.Uburyo bwo gutanga urumuri ni itara rya fluorescent hamwe n itara risohora gaze.LED ntabwo ifite filament, kandi urumuri rwayo ntirutangwa no gushyushya filament, ni ukuvuga, ntirubyara urumuri rwemerera umuyaga gutembera mumirongo ibiri.LED isohora imirasire ya electromagnetique (inshuro nyinshi cyane yo kunyeganyega), iyo iyi mipfunda igeze hejuru ya 380nm no munsi ya 780nm, uburebure bwumuraba hagati bugaragara ni urumuri rugaragara, urumuri rugaragara rushobora kubonwa namaso yabantu.

Diyode itanga urumuri irashobora kandi kugabanywa mubice bisanzwe bya monochrome itanga urumuri, urumuri rwinshi-rumuri rutanga urumuri, urumuri rwinshi-rumuri rutanga urumuri, diode ihindura ibara, urumuri rukwirakwiza urumuri, rukoresha amashanyarazi. diode isohora urumuri, infrarafarike itanga urumuri hamwe na diode mbi itanga urumuri.

gusaba:

1. Icyerekezo cy'ingufu za AC

Igihe cyose umuzunguruko uhujwe n'umurongo w'amashanyarazi wa 220V / 50Hz, LED izacanwa, byerekana ko umuriro uri.Agaciro ko guhangana kurubu kugarukira R ni 220V / NIBA.

2. Itara ryerekana icyerekezo cya AC

Koresha LED nkumuzingi kumatara yerekana urumuri rwinshi.Iyo switch ihagaritswe kandi itara rikazima, ikigezweho gikora uruziga runyuze muri R, LED na lampo ya EL, hanyuma amatara ya LED akayangana, bikaba byoroshye kubantu kubona icyerekezo cyijimye.Muri iki gihe, ikigezweho muri loop ni gito cyane, kandi itara ntirizamurika.Iyo switch ifunguye, itara rirakinguye kandi LED irazimya.

3. Itara ryerekana amashanyarazi

Umuzunguruko ukoresha amabara abiri (cathode isanzwe) LED nkurumuri rwerekana urumuri rwa AC.Amashanyarazi kuri sock agenzurwa na switch S. Iyo LED itukura iri, sock nta mbaraga ifite;iyo icyatsi kibisi LED kiri, sock ifite imbaraga.
