Nigute ushobora kumenya ubwiza bwurumuri rwa LED?

Hamwe niterambere ryubumenyi nubuhanga, amatara ya LED arashobora kugaragara ahantu hose. Uyu munsi ndakubwira uburyo bwo kumenya ubwiza bwurumuri rwa LED. Isoko rya LED ryumucyo rivanze, kandi ibiciro byibicuruzwa biva mubakora bisanzwe nibicuruzwa biva mubakora kopi biratandukanye cyane.

Turashobora gukora ibimenyekanisha byambere dushingiye kumiterere yoroshye, kandi turashobora kuvuga mubyukuri niba ubwiza ari bwiza cyangwa bubi.

Irashobora kumenyekana cyane cyane mubice bikurikira:

1. Reba ingingo zigurisha. Imirongo yumucyo LED yakozwe nabakora inganda zisanzwe za LED zikora hifashishijwe ikoranabuhanga rya SMT patch, ukoresheje paste yo kugurisha no kugurisha ibicuruzwa. Kubwibyo, kugurisha kugurisha kumurongo wamatara ya LED biroroshye kandi umubare wabagurisha ntabwo ari munini. Ihuriro ryabacuruzi riva kuri padi ya FPC kugeza kuri electrode ya LED muburyo bwa arc.

2. Reba ubuziranenge bwa FPC. FPC igabanijwemo ubwoko bubiri: umuringa wambaye umuringa. Umuringa wumuringa wibibaho byambaye umuringa uragaragara. Niba urebye neza, urashobora kuyibona uhereye kumihuza hagati ya padi na FPC. Umuringa uzungurutswe uhujwe cyane na FPC kandi urashobora kugororwa uko bishakiye nta padi iguye. Niba ikibaho cyambaye umuringa cyunamye cyane, amakariso azagwa. Ubushyuhe bukabije mugihe cyo kubungabunga nabyo bizatera padi kugwa.

3. Reba isuku yubuso bwumurongo wa LED. Ubuso bwurumuri rwa LED rwakozwe hakoreshejwe tekinoroji ya SMT rufite isuku cyane, nta mwanda cyangwa ikizinga kigaragara. Nuburyo bwose ubuso bwurumuri rwimpimbano rwa LED rwakozwe no gusudira intoki, hasigara irangi nibimenyetso byogusukura.

4. Reba ibipfunyika. Imirasire ya LED isanzwe ipakirwa mumashanyarazi arwanya static, mumuzingo wa metero 5 cyangwa metero 10, kandi igashyirwaho kashe mumifuka ipakira anti-static nubushuhe. Gukoporora verisiyo yumucyo LED ikoresha reel yongeye gukoreshwa idafite imifuka yo gupakira anti-static nubushuhe. Niba witegereje neza kuri reel, urashobora kubona ko hari ibimenyetso n'ibishushanyo hejuru hejuru ibumoso igihe ibirango byakuweho.

5. Reba ibirango. Ibisanzwe LED yumucyo wapakira imifuka hamwe na reel bizaba byanditseho ibirango, ntabwo byanditse.

6. Reba kumugereka. Imirongo isanzwe ya LED izaza ifite amabwiriza yo gukoresha hamwe n’ibisobanuro byerekana urumuri mu gasanduku gapakira, kandi bizashyirwaho kandi ibyuma bifata urumuri rwa LED cyangwa abafite amakarita; mugihe kopi yimiterere ya LED yumucyo idafite ibyo bikoresho mubisanduku bipfunyika, kuko nubundi, ababikora bamwe barashobora kuzigama amafaranga.

Icyitonderwa kumurongo

1. Ibisabwa kumurika kuri LED biratandukanye bitewe nibihe bitandukanye nibicuruzwa. Kurugero, niba amatara ya LED yimitako ashyizwe mumasoko manini manini, dukeneye kugira umucyo mwinshi kugirango ushimishe. Kubikorwa bimwe byo gushushanya, hari ibicuruzwa bitandukanye nka LED yamurika na LED ibara ryamabara.

2. Ubushobozi bwo kurwanya-static: Ubushobozi bwo kurwanya-LEDs ifite imbaraga zikomeye zo kurwanya-static zifite ubuzima burebure, ariko igiciro kizaba kinini. Mubisanzwe antistatike nibyiza hejuru ya 700V.

3. LED ifite uburebure bumwe nubushyuhe bwamabara bizagira ibara rimwe. Ibi ni ingenzi cyane kumatara ahujwe kubwinshi. Ntugatanga umusaruro mwinshi cyane mumatara amwe.

4. Umuyoboro w'amazi niwo mugihe iyo LED ikora amashanyarazi muburyo butandukanye. Turasaba gukoresha ibicuruzwa bya LED hamwe nuduce duto duto.

5. Ubushobozi butagira amazi, ibisabwa kumatara yo hanze no murugo LED biratandukanye.

6. Inguni ya LED itanga urumuri rufite uruhare runini kumatara ya LED kandi ifite ibisabwa cyane kumatara atandukanye. Kurugero, turasaba gukoresha dogere 140-170 kumatara ya LED fluorescent. Ntabwo tuzasobanura abandi birambuye hano.

7. Imashini ya LED igena ubwiza bwibanze bwa LED. Hariho ibirango byinshi bya LED chip, harimo nibiva mubirango byo hanze ndetse nibiva muri Tayiwani. Ibiciro byibirango bitandukanye biratandukanye cyane.

8. Ingano ya chip ya LED nayo igena ubwiza nubucyo bwa LED. Mugihe duhitamo, tugerageza guhitamo chip nini, ariko igiciro kizaba kiri hejuru.
