Kumenya byoroshye ubuziranenge bwa LED

Binyuze mumyaka myinshi yo gukora hamwe nabakora luminaire, mubisanzwe twumva ko abakora luminaire badashaka kugura amashanyarazi meza ya LED.Ibinyuranye nibyo, ntibazi gutandukanya amashanyarazi yaguzwe LED, kandi bafite impungenge zo kuba barishyuye igiciro kinini kumashanyarazi ya LED yo mu rwego rwo hasi.Kubwibyo, nkumukora urumuri, biragoye gutanga ibitekerezo kugura amashanyarazi ya LED.Kuberako ubwiza bwumuriro w'amashanyarazi butoroshye kugenzura, bumaze amasaha 4 muruganda rwacyo rutunganya, ndetse bamwe bafite imyaka 24-72.Nyamara, ibicuruzwa bishaje mubisanzwe hafi 5% cyangwa birenga mugihe cyamezi 3-6 yo kubyara.Akenshi, mubihe nkibi, abakora luminaire barababara, bahinduka abakiriya, kandi babura abakiriya.

Tuvuge iki ku gufata ubuziranenge bw'amashanyarazi ya LED?Turashobora kubimenya mubice bikurikira:
Icya mbere:gusunika chip-IC.
Ibyingenzi bikubiye mumashanyarazi atwara ni uruziga ruhujwe, kandi ibyiza nibibi byumuzunguruko uhuriweho bishobora kugira ingaruka zitaziguye kumashanyarazi yose.Umushoferi uhuza imirongo yinganda nini zapakiwe muruganda runini kandi ruciriritse;umushoferi yinjije tekinoroji yumuzunguruko yinganda ntoya itunganya ni uguhita wandukura igishushanyo mbonera cya promotion yimishinga yinganda nini, ugashaka gupakira inganda ntoya nini nini zipakira, zidashobora kwemeza guhuza ibice byuzuzanya.no kwizerwa, bivamo imbaraga zo gutwara zidafite agaciro kubwimpamvu nyuma yigihe cyo gukoresha.Kubwibyo, umuzunguruko uhuriweho kumashanyarazi ya LED wanze gukonjeshwa, bikaba byoroshye ko uwakoze itara asobanukirwa gahunda yumuzunguruko hamwe no kubara ibiciro byizamurwa, kugirango harebwe igiciro cyiza cyibicuruzwa bitanga amashanyarazi.

Icya kabiri:Guhindura.
Igikorwa gikora gishobora gufatwa nkikigo cyubwonko bwubwonko bwumuntu uhindura amashanyarazi, mugihe imbaraga zisohoka hamwe nubushyuhe bwo hejuru bugenwa na transformateur.Impinduka zifata amashanyarazi ya AC - ingufu za electromagnetic - imbaraga za DC, nimbaraga za kinetic zirashobora kuzuza imashini.Ibyingenzi bigize transformateur nibyingenzi hamwe na pake ya wire.
Ubwiza bwibanze nibyingenzi kuri transformateur, ariko nkibumba, ntabwo byoroshye kumenya.Kugaragara byoroshye kugaragara ni: isura ni crisp, yuzuye kandi yaka, kandi uruhande rwinyuma rusizwe neza kandi icyambu gisohoka nigicuruzwa cyiza.Kugeza ubu, imbaraga za rukuruzi zikoreshwa na Shanghai Nuoyi ni PC44 ya magnetiki ya PC44, ikoreshwa mu gukora ibumba, ituma imikorere ihanitse itanga amashanyarazi.
Ipaki yinsinga ikozwe mumuringa wintoki.Ubwiza bwibicuruzwa byumuringa wumuringa nigice cyingenzi mubuzima bwa serivisi ya reaction ya reaction.Umugozi wambaye umuringa wa aluminiyumu ingana ni 1/4 igiciro cyinsinga z'umuringa utukura.Kubwimpamvu zigiciro nigitutu cyakazi, abakora transformateur bakunze kuvanga transformateur hamwe nu muringa wambaye umuringa wa aluminium.Noneho, iyo ubushyuhe bwa transformateur buzamutse, ibyangiritse ntacyo bikora, bigatuma amashanyarazi ahinduka kandi urumuri rwose ntirukora.Nkigisubizo, ibikoresho byinshi byo kumurika, cyane cyane abafite ibikoresho byo guhinduranya amashanyarazi byasubitswe, mubisanzwe bihindagurika hejuru no hasi nyuma y amezi 6 yo kubyara.Nigute ushobora gutandukanya niba insinga y'umuringa ari insinga itukura y'umuringa cyangwa aluminiyumu yambaye umuringa?Koresha urumuri kugirango ucane kandi utwike vuba umuringa wambaye umuringa.Irashobora kandi gupima neza agaciro ko guhangana na colenoid coil.

Icya gatatu:ubushobozi bwa electrolytike hamwe na chip ceramic capacator.
Twese tuzi ko twese tuzi ubuzima bwiza na serivise yubuzima bwa electrolytike, kandi twese turabifata neza.Ariko, akenshi twirengagiza amabwiriza yubuziranenge bwibicuruzwa byohereza ibicuruzwa hanze.Mubyukuri, ubuzima bwa capacitor ikomokaho bubangamira cyane ubuzima bwumuriro wo guhinduranya.Inshuro ikora yumuriro wamashanyarazi kumurongo wanyuma ugera inshuro 6.000 kumasegonda, bigatuma habaho kwiyongera kwubuzima bwa capacitori no gukora imiti nkumwanda.Hanyuma, bateri ya lithium electrolyte irashyuha iraturika.Birasabwa cyane kohereza ibicuruzwa bya electrolytike: hitamo uburyo bwihariye bwa electrolytike kuri LED, kandi ibisobanuro rusange byerekana bitangirira kuri L. Kuri iki cyiciro, uburyo bwo kohereza amashanyarazi mu mahanga byose ni ubushobozi bwa electrolytike hamwe nubuzima bwa Aihua.

Ububiko bwa Ceramic: Ibikoresho bigabanijwemo X7R, X5R na Y5V, kandi ubushobozi bwihariye bwa Y5V bushobora kugera kuri 1/10 cyagaciro kihariye, kandi agaciro gasanzwe kerekana gusa volt 0 mugihe cyo gukora.Kubwibyo, uku kwihanganira gato no guhitamo nabi bizanatuma habaho itandukaniro ryibiciro, bigabanye cyane ubuzima bwa serivisi yo guhinduranya amashanyarazi.

Icya kane:ihame ryumuzunguruko nuburyo bwo gusudira bwo guhindura ibicuruzwa bitanga amashanyarazi.
Tandukanya ubuziranenge bwa gahunda yo gushushanya: Usibye icyerekezo cya tekiniki yumwuga, irashobora kandi gutandukanywa ukurikije uburyo bumwe na bumwe bugaragara, nkuburyo bushyize mu gaciro bwibigize, isuku, ikirere gitondetse, gusudira neza, n'uburebure busobanutse.Umutekinisiye mwiza ntabwo akunda gushushanya.Kubitsinga, ubukorikori hamwe nibigize nabyo ni ibintu bikomeye byerekana imbaraga nke za tekinike.
Uburyo bwo gusudira: gusudira intoki hamwe nuburyo bwo gusudira.Nkuko twese tubizi, uburyo bwo gusudira bwimpinga yuburyo bwiza bwo gukoresha imashini bugomba kuba bwiza kuruta gusudira intoki.Uburyo bwo kumenyekanisha: niba hari inyuma ya kole itukura (inzira yo kugurisha paste yingirakamaro yo gutunganya + ibikoresho byo gusudira amashanyarazi nabyo birashobora kurangiza gusudira impinga, ariko igiciro cyacyo kiri hejuru).

Igikoresho cyo kugenzura SMD ikibanza cyo gusudira: AOI.Mumuhuza wa SMD, ikigo gishobora kugenzura imiterere ya desoldering, kugurisha ibinyoma, no kubura ibice.

Kuri iki cyiciro, urumuri ruzamurika nyuma yigihe cyo gukoreshwa, ibyo bikaba biterwa ahanini no kugurisha kugurisha amashanyarazi cyangwa amashanyarazi ya LED.Igenzura ryangirika ryibicuruzwa ntabwo byoroshye gutsinda igenzura ryashaje, birakenewe rero gukoresha AOI kugirango ugenzure ubwiza bwibintu bitanga amashanyarazi.

Icya gatanu:Reba ibice bishaje hamwe nubushyuhe bwo hejuru bwubusaza bwinshi kugirango uhindure ibicuruzwa bitanga amashanyarazi.

Nubwo ibikoresho byiza nibicuruzwa byaba byiza gute mubikoresho fatizo nibicuruzwa bitanga ingufu, cyangwa gusaza bigomba kugenzurwa.Biragoye kugenzura raporo yubugenzuzi yinjira yibikoresho bya elegitoronike hamwe na transformateur.Gusa ukurikije gusaza kw'itangwa ry'amashanyarazi no kugenzura ubushyuhe bwo hejuru bwo kugenzura icyumba gikomeza ubushyuhe bwo hejuru, birashobora kwizerwa ubuziranenge bw'amashanyarazi kandi niba ibikoresho fatizo bifite ingaruka z'umutekano bishobora kugenzurwa.

Ingaruka z'umubare munini w'ubushyuhe bwo hejuru bwo gupima ubushyuhe bwo hejuru: Ubushobozi buke bwo guhindura amashanyarazi muriki cyiciro buri hagati yigihumbi kugeza ku ijana, kandi uku kudakora kuzaboneka gusa mugihe ibihumbi nibihumbi bikomeza ubushyuhe bwo hejuru.

Icyumba cyo hejuru cyubushyuhe burashobora kwigana ibidukikije bikaze aho amashanyarazi akorera.Kugenzura icyitegererezo ukurikije amahame akomeye birashobora kwerekana ibibazo byinshi nkibishushanyo mbonera bya siyansi, ibikoresho bibi, ibikoresho byo kumurika bidafite akamaro, hamwe ningaruka zumuriro wumuriro mwinshi.

Gusaza igihe kirekire mubushyuhe bwicyumba: hitamo kunanirwa gutunguranye nka desoldering, ibice bitemba, ingaruka, nibindi, gushungura imikorere idahwitse yibigize, kandi bigabanye kugabanya igipimo cyo kunanirwa kwibicuruzwa byarangiye (1% kugeza 1/1000) .

Ku bushyuhe bwicyumba, gusaza bitwara imashini nyinshi zishaje, ibikoresho nabakozi.Buri munsi, 100.000 inganda zitunganya zihindura amashanyarazi no kuzimya.Imashini n'ibikoresho bishaje bifite ubuso bwa metero kare byibuze 500, hamwe n'imyanya irenga 10,000 yo gusaza, kandi gusaza k'umurongo w’ibicuruzwa byarangiye, bikaba bidasanzwe mu nganda.
