Iriburiro: Umukengeri uhindagurika hamwe nabandi bo mumajyepfo yubumenyi n'ikoranabuhanga byateye uruhererekane buhuza Diomu-Gusohora Diode-Gusohora Diode-Gusohora Diode-Guhuza Diode-Gusohora Diode Diode irashobora gukora munsi yinzinguzingo kandi isobanura ibizunguruka, hamwe nubushobozi bwa quanion yo muri 20.09% na 21.15%. Byongeye kandi, muguhuza ibice byinshi byahujwe, akanama gashobora guterwa mu buryo butaziguye urugo rwa AC Ac'ububasha udakeneye imirongo igoye. Munsi ya 220 V / 50 HZ, Imbaraga Zikora Igicapo gitukura no gukina Umwanya ni 15.70 LM W-1, hamwe numucyo wo guhinduka urashobora kugera kuri CD ya 25834.
Amavuta yo gusohora urumuri (LED) yabaye ikoranabuhanga ryoroheje kubera imikorere yabo minini, ndende, leta n'ibidukikije n'ibidukikije bisabwa ku isi. Nka Semiconductor PN Diode, LED irashobora gukora gusa munsi yimodoka ya voltage yo hasi (DC). Kubera kwishyuza no gukomeza gutera inshinge, kuregwa no gushyushya joule gushyuza mu gikoresho, bityo bigabanya umutekano mubikorwa. Byongeye kandi, amashanyarazi yisi ahanini ashingiye cyane kuri voltage ndende, kandi ibikoresho byinshi byo murugo nkuko amatara ya LED adashobora gukoresha mu buryo butaziguye. Kubwibyo, iyo iyobowe niko amashanyarazi yo murugo, acc apfique yinyongera arasabwa nkumuryango wa voltage ahishwa maremare ac mububasha-voltage dc imbaraga za DC. Igitabo gisanzwe gikubiyemo umutego wo kugabanya voltage yingenzi hamwe nu Rwanda rusubira inyuma kugirango ukosore ibikubiye AC (reba Ishusho 1a). Nubwo guhindura imikorere ya AC-DC ibihindura byinshi birashobora kugera hejuru ya 90%, haracyariho ingufu mugihe cyo guhinduka. Byongeye kandi, guhindura umucyo wa LED, umuzenguruko utwara utwara ibinyabiziga ukwiye gukoreshwa mugukoresha imbaraga za DC kandi utange ikigezweho kuri LED (reba ishusho yinyongera 1b).
Kwizerwa k'umuzenguruko bashoferi bizagira ingaruka ku kuramba amatara ya LED. Kubwibyo, kumenyekanisha abashoferi ba AC-DC ntabwo bitera amafaranga yinyongera (kubara hafi 17% byigiciro cya LEMP), ariko nanone byongera amashanyarazi kandi bigabanya amatara yinyamanswa. Ibikoresho rero, bitezimbere iyobowe cyangwa electroluminescent (el) bishobora guterwa mu buryo butaziguye mu rugo 110 v / 220 v Voltas ya 50 h / 220 v
Mu myaka mike ishize, ac itwarwa na ac electroluminescent (ac-el) yerekanwe. Ubusanzwe VolegonIC ya AC ya elegitoronike igizwe nifu ya fluorescent isohora igice cya sasheri hagati y'ibice bibiri bikabuza (Ishusho 2a). Gukoresha urwego rwo kugenzura birinda infashanyo zabatwara hanze, ntabwo rero hariho itangwa ritemba binyuze mubikoresho. Igikoresho gifite imikorere ya capabori, kandi munsi yimodoka yumurima wamashanyarazi muremure, electron yabyaye imbere irashobora kumurongo urashobora gufata icyemezo cyo gufunga. Nyuma yo kubona ingufu zihagije za kinetic, electron kugongana na lupfantcent ikigo, itanga disikuru no gusohora urumuri. Bitewe no kudashobora kwinjizamo electron kuva hanze ya electrode, umucyo no gukora ibi bikoresho biraryoshye cyane, bigabanya porogaramu zabo mubijyanye no kumurika no kwerekana.
Kugirango utezimbere imikorere yacyo, abantu bateguye balla ya elegitoronike ya elegitoroniki ifite urwego rumwe rwinshi (reba ishusho yinyongera 2b). Muri iyi miterere, mugihe cyiza cyo kuzunguruka cya AC Drive, utwara igirego cyatewe mu buryo butaziguye ku rubanza rwasohotse muri electrode yo hanze; Guhumeka neza kurasa birashobora kugaragara no kwizirika nubundi bwoko bwishyurwa bitwara mbere. Ariko, mugihe kibi cyinzira mbi ya ac, abatwara infashanyo zizasohoka mu gikoresho bityo ntibazasohora urumuri rworoshye. Byongeye kandi, kubera ubushobozi bwibikoresho byibikoresho, imikorere ya electrouminence y'ibikoresho byombi bya ac ni ibintu byihariye bya Kilohertz nyinshi, kandi bikaba bigorana kuba bihuye nimbaraga zisanzwe zurugo rusanzwe (50 hertz / 60 hertz).
Vuba aha, umuntu yatanze igikoresho cya elegitoroniki ya AC ishobora gukora kuri 50 HZ / 60 HZ. Iki gikoresho kigizwe nibikoresho bibiri bibangikanye bya DC (reba Ishusho 2C). Mu mashanyarazi ngufi ahigamo electrode yo hejuru yibikoresho bibiri kandi ihuza amashanyarazi yo hepfo kugeza kumashanyarazi ya ac, ibikoresho bibiri birashobora guhinduka. Kuva mubitekerezo byumuzunguruko, iki gikoresho cya AC-DC kiboneka muguhuza igikoresho cyimbere nigikoresho gihindura murukurikirane. Iyo igikoresho cyimbere cyafunguye, igikoresho gihindagurika cyazimye, gikora nkumurwanya. Bitewe no kuba hari irwariritse, imikorere ya electrouminence ni hasi cyane. Byongeye kandi, ibikoresho byo gusohora urumuri birashobora gukora gusa voltage nke kandi ntibishobora guhuzwa na 110 v / 220 v. Nkuko bigaragara ku gitsina cyinyongera 3 hamwe nimbonerano yinyongera 1, imikorere (umucyo nimbaraga) byibikoresho bya AC-DC Ibikoresho byimbaraga byateganijwe bitwawe nibikoresho byibikoresho bya DC. Kugeza ubu, nta gikoresho cya ac-DC gishobora guterwa mu buryo butaziguye n'amashanyarazi yo murugo saa 110 v / 220 v, 50 hz / 60 hz, kandi ifite imikorere minini kandi ifite ubuzima burebure kandi burebure.
Chen Shumung nitsinda rye baturutse muri kaminuza yubumenyi n'ikoranabuhanga byateye uruhererekane buhuza Diode-Gusohora Diode Gukoresha Diode Gukoresha Diode Gukoresha Transparent Kuyobora Indium zinc. Diode irashobora gukora munsi yinzinguzingo kandi isobanura ibizunguruka, hamwe nubushobozi bwa quanion yo muri 20.09% na 21.15%. Byongeye kandi, muguhuza ibice byinshi byahujwe, akanama gashobora guterwa mu rugo rutaziguye mu rugo. Gucomeka byateye imbere no gukina akadomo kamabaniko birashobora gutanga ubukungu, byoroshye, neza, kandi bihamye, kandi bihamye byoroheje-bya leta bishobora gukoreshwa mu buryo butaziguye.
