Isano iri hagati yubwiza bwamatara ya LED nogutanga amashanyarazi
LED ifite ibyiza byinshi nko kurengera ibidukikije, kuramba, gukoresha amashanyarazi menshi (gukoresha urumuri rugeze kuri 130LM / W ~ 140LM / W), kurwanya umutingito, nibindi. Mu myaka yashize, ikoreshwa ryarwo ryateye imbere byihuse mu nganda zitandukanye. Mubyigisho, ubuzima bwa serivisi ya LED ni amasaha 100.000, ariko mubikorwa nyabyo byo gusaba, bamwe mubashushanya amatara ya LED ntibumva neza cyangwa guhitamo nabi imbaraga zo gutwara LED cyangwa gukurikirana buhumyi igiciro gito. Nkigisubizo, ubuzima bwibicuruzwa bimurika LED bigufi cyane. Ubuzima bwamatara mabi ya LED ntabwo ari munsi yamasaha 2000 ndetse no munsi. Igisubizo nuko ibyiza byamatara ya LED bidashobora kugaragara mubisabwa.
Bitewe numwihariko wo gutunganya LED no kuyikora, ibiranga ubu na voltage biranga LED ikorwa nababikora batandukanye ndetse nabakora uruganda rumwe mugice kimwe cyibicuruzwa bifite itandukaniro rinini kubantu. Dufashe ibisobanuro bisanzwe byimbaraga-1W yera LED nkurugero, ukurikije amategeko agezweho ya voltage ya LED, ibisobanuro bigufi biratangwa. Mubisanzwe, voltage yimbere ya 1W yumucyo wera ikoreshwa ni 3.0-3.6V, ni ukuvuga, iyo yanditseho 1W LED. Iyo ikigezweho kinyuze muri mA 350, voltage hejuru yacyo irashobora kuba 3.1V, cyangwa irashobora kuba izindi ndangagaciro kuri 3.2V cyangwa 3.5V. Kugirango ubuzima bwa 1WLED bugerweho, uruganda rusange rwa LED rusaba ko uruganda rwamatara rwakoresha 350mA. Iyo umuyoboro wimbere unyuze muri LED ugeze kuri mA 350, kwiyongera gake mumashanyarazi yimbere imbere ya LED bizatera LED imbere imbere kuzamuka cyane, bigatuma ubushyuhe bwa LED buzamuka kumurongo, bityo kwihuta kwangirika kwurumuri rwa LED. Kugabanya ubuzima bwa LED ndetse no gutwika LED mugihe bikomeye. Bitewe numwihariko wa voltage nimpinduka zubu za LED, hasabwa ibisabwa bikomeye kumashanyarazi yo gutwara LED.
LED umushoferi nurufunguzo rwa LED luminaire. Ni nkumutima wumuntu. Kugirango ukore LED nziza cyane yo kumurika, birakenewe kureka voltage ihoraho kugirango itware LED.
Ibihingwa byinshi bifite ingufu nyinshi za LED bipfunyika ubu bifunga LED nyinshi kugiti cye hamwe no murukurikirane kugirango bibyare 20W, 30W cyangwa 50W cyangwa 100W cyangwa ingufu za LED. Nubwo mbere yipaki, zatoranijwe neza kandi zihuye, hariho mirongo na magana LED imwe kugiti cye kubera ubwinshi bwimbere. Kubwibyo, ibicuruzwa bipakiye cyane-LED ibicuruzwa biracyafite itandukaniro rinini muri voltage nubu. Ugereranije na LED imwe (muri rusange itara rimwe ryera, itara ryatsi, urumuri rwubururu rukora voltage ya 2.7-4V, itara rimwe ritukura, urumuri rwumuhondo, urumuri rwa orange rukora voltage ya 1.7-2.5V) biratandukanye cyane!
Kugeza ubu, ibicuruzwa by'itara rya LED (nk'ibirindiro, ibikombe by'amatara, amatara ya projection, amatara yo mu busitani, n'ibindi) byakozwe n'ababikora benshi bakoresha imbaraga zo kurwanya, ubushobozi ndetse no kugabanya ingufu za voltage, hanyuma bakongeramo diode ya Zener kugirango batange amashanyarazi kuri LED. Hariho inenge zikomeye. Icya mbere, ntigikora. Ikoresha imbaraga nyinshi kumurongo wo hasi. Irashobora no kurenga imbaraga zikoreshwa na LED, kandi ntishobora gutanga disiki-ndende. Iyo ikigezweho ari kinini, imbaraga zikoreshwa kumurongo wamanutse zaba nini, urumuri rwa LED ntirushobora kwemezwa kurenza ibyo rusanzwe rukora. Mugushushanya ibicuruzwa, voltage hejuru ya LED ikoreshwa mugutwara amashanyarazi, bikaba bitwara urumuri rwa LED. LED itwarwa nuburwanya hamwe nubushobozi bwo kumanuka-hasi, kandi umucyo wa LED ntushobora guhagarara neza. Iyo amashanyarazi atangwa ari make, umucyo wa LED uhinduka umwijima, kandi iyo amashanyarazi yatanzwe ari menshi, umucyo wa LED uba mwinshi. Birumvikana ko inyungu nini yo kurwanya na capacitive intambwe-hasi yo gutwara LED nigiciro gito. Kubwibyo, ibigo bimwe bimurika LED biracyakoresha ubu buryo.
Bamwe mubakora, kugirango bagabanye igiciro cyibicuruzwa, bakoresheje voltage ihoraho kugirango batware LED, nabo bazana urukurikirane rwibibazo bijyanye numucyo utaringaniye wa buri LED mubikorwa rusange, LED ntishobora gukora muburyo bwiza, nibindi. .
Gutwara isoko ihoraho nuburyo bwiza bwo gutwara LED. Iyobowe nisoko ihoraho. Ntabwo ikeneye guhuza imipaka igabanya ubukana mumasoko asohoka. Ibiriho byanyuze muri LED ntabwo byatewe nimpinduka zo mumashanyarazi zituruka hanze, impinduka zubushyuhe bwibidukikije, hamwe nibisobanuro bya LED. Ingaruka nugukomeza guhoraho no gutanga umukino wuzuye kubintu bitandukanye byiza biranga LED.
