4 Tekinoroji yingenzi yo kumurika LED
Guhitamo no gutunganya LED
Hariho ubwoko butatu bwingenzi bwa LED mubijyanye nimiterere: imwe iyobowe (inguni iyobora) LED, icyerekezo cyagenwe muri rusange ni mA 20, imbaraga ni nto, kandi guhuza byinshi bisa nkibisabwa kugirango urumuri; ikindi ni chip imwe imwe ya chip hejuru ya Chip LED, umuyagankuba wapimwe muri rusange urenze mA 50 (kuri ubu igipimo ntarengwa cyagenwe cya LED kigera kuri mA 1000), imbaraga nini, kandi irashobora gukoreshwa wenyine; icya gatatu ni uguhuza amashanyarazi mato mato kugirango agere ku mbaraga ndende, ni ukuvuga guhuza Power LED.
Gukoresha LED nyinshi murwego rumwe bifite igiciro gito cyumusaruro kandi birakwiriye kumurika ahantu hanini, ariko bisaba gahunda iboneye. Iyo ukoresheje diode ifite ingufu nke, kugirango ukore itara rimwe ryujuje ibyifuzo byo gucukura amakara, diode nyinshi igomba gukoreshwa murwego rumwe. Ibi bizana ikibazo cyukuntu voltage ikoreshwa nuburyo bwo kugenzura imiyoboro yose ya diode mu buryo bubangikanye kandi mu itsinda kugira ngo byuzuze ibisabwa by’umuzunguruko utekanye. Kuberako imbaraga z'umuzunguruko zifite umutekano imbere ni 24, 18, 12 V, nibindi, imigezi ijyanye nibisabwa mumutekano wimbere igomba kuba 400, 600, na 1000 mA. Kubububasha buke busanzwe busanzwe butanga urumuri, imiterere yumurimo wa voltage muri rusange ni 3 kugeza 4 V naho amashanyarazi akora ni 20 mA. Niba 18 V / 600 mA yaratoranijwe, amatsinda 30 arashobora guhuzwa murwego rumwe, 5 murukurikirane nkitsinda, hanyuma résistoriste ikwiye ihujwe murukurikirane. Umuvuduko wa voltage ya buri diode uri munsi ya 3.6V, wujuje ibisabwa byubwoko bwumutekano imbere nubwiza. Iyo umwe cyangwa itsinda ryangiritse, ntabwo bigira ingaruka kumurimo wizindi diode cyangwa kumurika.
Iyo LED nyinshi ihujwe hamwe, imbaraga za LED imwe ni nto kandi ubushyuhe butangwa burasa. Mugihe cyose LED zitunganijwe neza kandi Cu agace kanditseho ikibaho cyumuzunguruko cyinshi, ibisabwa byo gukwirakwiza ubushyuhe birashobora kuba byujujwe.
Iyo ingufu za diode zikoreshwa cyane, igishushanyo mbonera cyizunguruka imbere ntikikiri ikibazo. Icyangombwa nuburyo bwo gutegura diode kugirango uhuze ibikenerwa byo gucukura amakara.
