Ibice byingenzi bigize ecran nini bigizwe nisaro ryayobowe nabashoferi. Kubera imitekerereze ya LED ku mashanyarazi ahamye, amashanyarazi akomeye arashobora gutera gusenya ibintu bisohora urumuri. Kubwibyo, ingamba zifatika zigomba gufatwa mugihe cyo kwishyiriraho ecran nini kugirango wirinde ibyago byamatara yapfuye.
01 LED Erekana Imbaraga za Mugaragaza
Voltage ikora ya ecran nini iyobowe na 5v, hamwe nubushakashatsi rusange buri munsi ya 20Ma iranga Leds igena intege nke zayo ku mashanyarazi na voltage adasanzwe cyangwa ihungabana ridasanzwe. Ibi biradusaba kumenya ibi mubikorwa byo gukora no gukoresha, gutanga ibitekerezo bihagije, kandi gufata ingamba zifatika zo kurinda ecran nini. Kandi imbaraga zihuriweho nuburyo bukunze gukoreshwa muburyo bwo kuyoboye ecran nini.
Kuki imbaraga zigomba gushingwa? Ibi bifitanye isano nuburyo bwo gukora bwo guhindura amashanyarazi. Ibikorwa byacu bya LED byerekana amashanyarazi nigikoresho gihindura Ac 220v Mains Power muri DC 5V DC Imbaraga zisohoka zinyuze muburyo bwo gusohora ibirungo. Kugirango habeho gucika intege kwa AC / DC ihindura amashanyarazi, uruganda rukora amashanyarazi rwahujije umutsima wa EMI mu gishushanyo mbonera cya Ac220V hakurikijwe umurongo uteganijwe mu rwego rwa 3c. Kugirango ubone umutekano wa AC220V winjijwe, ibikoresho byose byamazu bizagira akayungurura kuyungurura mugihe cyo gukora, hamwe nudusimba nka 3.5ma kumashanyarazi. Voltage yatemba ni hafi 110v.
Iyo ecran ya LED idashinze ishingiro, kurimbuka ntabwo bishobora gutera kwangirika cyangwa itara ryaka. Niba amashanyarazi arenga 20 akoreshwa, hakusanyirijwe hamwe nubuso bwa 70ma cyangwa byinshi. Birahagije gutera umurinzi watemba gukora no kugabanya amashanyarazi. Ibi kandi ni ukubera iki ecran zacu za LED idashobora gukoresha kurinda. Niba uburinzi bwa leakage budahujwe na ecran ya LED ntabwo ihagaze neza, ibirenze amashanyarazi bizarenze umutekano wumubiri wumuntu. Voltage ya 110V irahagije kugirango itera urupfu! Nyuma yo gusora, voltage yimbaraga isaba isoko yegereye 0 kumubiri wumuntu. Yerekana ko nta tandukaniro riryo riri hagati yububasha numubiri wumuntu, hamwe nubudomo bwerekeza hasi. Rero, ecran ya LED igomba kuba ifite ishingiro.
02 Uburyo bukwiye hamwe nuburyo butari bwo bwo ku butaka bwakozwe
Abakoresha bakunze gukoresha uburyo butari bwo hasi hasi bwa LECEN, mubisanzwe harimo:
1.
2. Bikekwa ko itangazo rifungirwa ku gasanduku, kandi udusanduku duhujwe no gufunga hamwe n'inzego, impamvu nyaba ihuriweho igaragaza ko amashanyarazi nayo ashingiye kandi.
Hariho ubwumvikane buke muri ubwo buryo bubiri. Inkingi zacu zifitanye isano numufatiro andchor ya ancts, yinjijwe muri beto. Kurwanya beto biri murwego rwa 100-500 ω. Niba imyigaragambyo yimbere cyane, izaganisha ku kumeneka cyangwa kumeneka. Agasanduku kacu katewe nirangi, kandi irangi ni uwuyobora amashanyarazi, azatera ikibazo gikennye cyangwa kwiyongera k'amashanyarazi yo guhuza ibimenyetso byumubiri wa ecran. Igihe kirenze, ubuso bwikigo kinini cya ecran cyangwa imiterere izabona okiside n'ingese, kandi ikosore ibice bizagenda buhoro buhoro kubera ubushyuhe bwo kwaguka no kugabanuka buterwa no gutandukana nubushyuhe. Ibi bizatera intege nke cyangwa no kunanirwa kwuzuye ingaruka zifatika zimiterere ya ecran ya LED LES. Kora ingaruka z'umutekano. Kubaho kw'impanuka z'umutekano nko kumeneka ubu, amashanyarazi, kwivanga no kwangirika kwa chip.
None, ni ubuhe buryo busanzwe?
Imyandikire yimbaraga ifite terminal eshatu, ni ukuvuga terminal nzima, terminal itabogamye, hamwe na terminal. Uburyo bukwiye bwo kugereranya nugukoresha ibara ryicyatsi kibisinye duhurira insinga kugirango uhuze no gufunga amashanyarazi yose yinzovu murukurikirane, hanyuma ubayobore guhuza na terminal. Niba nta mpande zose zihari kurubuga, irashobora guhuzwa no gushyingurwa pipa nkimiyoboro y'amazi cyangwa imiyoboro yicyuma ihura nubutaka. Kugirango umenye neza, gusudira kuri mibiri isanzwe bigomba gukorwa, hanyuma insinga yubutaka igomba gufungwa cyane kuri terminal idahuza guhuza. Ariko, imiyoboro yaka kandi iturika nka gaze ntizakoreshwa. Cyangwa gushyingura electrode zihuriweho kurubuga. Umubiri wuruhande urashobora gukorwa mubyuma cyangwa imiyoboro yibyuma, yashyinguwe mu buryo butambitse cyangwa ahagaritse muburyo bworoshye. Ingingo yibanze igomba gutoranywa mukarere ka kure kugirango ibuhize abanyamaguru cyangwa ibinyabiziga byangiza umubiri. Iyo dutakaye, imyigaragambyo itegwe igomba kuba munsi ya 4 ohms kugirango irekure ku mwanya wa mbere. Twabibutsa ko inkuba zishingiye ku nkunga zisaba igihe runaka kugirango ugabanye ubutaka ubu mugihe cyo gusohora inkuba, bishobora kuganisha ku kwiyongera mubutaka mugihe gito. Niba ecran ya LED ishingiye ku murabyo ugereranya terminal, ububasha bwo hasi buzashyirwa hejuru ya ecran ya LED, kandi inkuba izashyikirizwa iyi nsinga ya ecran ya LED, itera ibikoresho. Impamvu rero yo kurinda ecran ya LED ntishobora guhuzwa ninkuba zishingiye kuri terminal, kandi terminal irinda igomba kuba byibura metero 20 kure yumurabyo. Irinde igihangano cyubutaka.
