Umwijima w'umukaraItara rya LEDni ko bigenda bikunze kugaragara. Gusobanura muri make impamvu zituma amatara ya LED yijima nta kindi uretse ingingo eshatu zikurikira.

Ibyangiritse by'umushoferi
Amasaro y'amatara ya LED arakenewe kugira ngo akore kuri voltage iri hasi ya DC (munsi ya 20V), ariko amashanyarazi yacu asanzwe ni voltage iri hejuru ya AC (AC 220V). Kugira ngo uhindure amashanyarazi akenewe kuri itara, ukeneye igikoresho cyitwa "LED constant current drive power."
Mu by’ukuri, igihe cyose ibipimo by’umushoferi bihuye n’urukiramende rw’itara, umuriro w’amashanyarazi ushobora gukoreshwa buri gihe no gukoreshwa mu buryo busanzwe. Imbere muri disiki biragoye, kandi igikoresho icyo ari cyo cyose (nk’ama-capacitor, ama-rectifier, n’ibindi) gishobora gutera impinduka mu muvuduko w’amashanyarazi, bigatuma itara rihinduka umwijima.

LED yahiye
LED ubwayo igizwe n'isaro rimwe ry'itara. Iyo rimwe cyangwa igice cyaryo kidacanywe, byanze bikunze bizatuma icyuma cyose cyijima. Amasaro y'itara muri rusange ahuzwa mu buryo bukurikiranye hanyuma agahuzwa mu buryo bungana - bityo rero iyo isaro runaka ry'itara rihiye, rishobora gutuma itsinda ry'amasaro y'itara rizimya.
Nyuma yo gushya, ubuso bw'isaro ry'itara bugira utudomo tw'umukara tugaragara. Rishakishe, koresha insinga kugira ngo urihuze n'inyuma y'itara, urigabanyirizeho umurongo, cyangwa urisimbuze n'isaro rishya ry'itara.

Itara rya LED ryangiritse
Icyo bita kwangirika k'urumuri ni uko urumuri rw'urumuri rugenda rugabanuka cyane - iki kibazo kigaragara cyane ku matara ashyushye n'ay'urumuri.
Amatara ya LED ntashobora kwirinda kwangirika k'urumuri, ariko umuvuduko wayo wo kwangirika k'urumuri ugenda buhoro, biragoye kubona impinduka ukoresheje amaso. Ariko, ntibikuraho amatara ya LED adakomeye, cyangwa amasaro y'urumuri adakomeye, cyangwa bitewe n'ibintu bifatika nko kudashira neza k'ubushyuhe, bigatuma urumuri rwa LED ruhita rwangirika.
