Izibane ze-LED zihlala zibona iimpazamo kunye neendlela zokulungisa

Indlela yokulungisa ukukhanya kwe-LED? UZhuhai ufundisa wonke umntu ukuba afunde ukuyenza. Iimpazamo ze-LED ezilula nazo ziyakwazi ukuzilungisa. Izibane ze-LED zihluke kwizibane zangaphambili ze-incandescent. Izibane ze-incandescent ngokusisiseko zaphukile. Ngokusisiseko, i-tungsten filaments iyatshiswa. Izibane ze-LED zihlukile. Izibane ze-LED zenziwe ngeesekethe ze-LED zokuqhuba kunye neentsimbi zesibane se-LED. Uninzi lwezibane ze-LED zinokulungiswa, kodwa ixabiso lezibane ze-LED aliphezulu. Amashumi amaninzi, ngoko ke akukho mntu ujongene nokulungiswa kwezibane ze-LED, ixabiso liphezulu, abanye abafuni ukulungisa, ixabiso liphantsi, ixabiso labasebenzi liphantsi kakhulu, ngoko linokulungiswa kuphela ngabasebenzisi. Indlela yokulungisa izibane ze-LED njengabasebenzisi ngokubanzi? Kukho izizathu ezininzi zokungaphumeleli kwezibane ze-LED, kodwa kukho ukusilela okulula. Kucetyiswa ukuba abasebenzisi bazame ukuzilungisa kwaye bazilolonge njengoko beziqhelisa. Izibane ze-LED zihlala zibona iimpazamo kunye neendlela zokulondoloza 1. Izibane ze-LED zonakaliswe. Oku kukusilela okuqhelekileyo. Ngokuqhelekileyo, xa izibane ze-LED zitshiswa, kuya kubakho amabala amnyama phezu komhlaba. Uqwalaselo olucokisekileyo lunokwahlulwa. Ukulungisa oku kulungiswa kwempazamo, kufuneka uxhobise intsimbi yejoni. Kodwa kuthekani ukuba akukho ntsimbi yesibane se-LED? Inokusetyenziswa 150 ωUkuchasana okusekhohlo kunye nokunene kuthatha indawo, ukuba umqhubi wangoku oqhubekayo unokudibaniswa ngokuthe ngqo. 2. Ukungaphumeleli komthamo wesihluzi. Ukukhanya okulula kwe-LED ngokubanzi kulungisa umbane we-AC ngokunyamezela kunye nokunciphisa uxinzelelo, kwaye emva koko amandla amaso wesibane se-LED ngokucoca i-capacitor. Ukuba ukusilela kwe-capacitor yokucoca kuya kubangela ukuba i-voltage ingazinzi, i-voltage ye-DC iphantsi, eyenza ukukhanya kwe-LED kube mnyama. Ukulinganisa umthamo we-capacitor yokucoca ngefayile ye-multimeter capacitor. Ukuba impazamo inkulu, impazamo inkulu kune-30%. Kuthetha ukuba amandla aye ehla. Fumana ukuxhathisa kombane kunye nomthamo omkhulu kunokulingana nepharamitha ye-capacitor. 3. Imodyuli yokunciphisa amandla okunciphisa yonakalisiwe. Imodyuli yokulahla amandla iquka i-capacitor capacitor kunye ne-resistance parallel. Ingasetyenziselwa ukulinganisa ukuba i-capacitance yayo kunye nokuchasana kunokonakala. 4. Buyela. Hlukanisa ukukhanya kwe-LED kwaye ukhangele ukuba kukho ukuqhawula kwi-input yangaphakathi kunye ne-output wiring. Ukuba kunjalo, sebenzisa i-iron soldering yombane ukuyilungisa. 5. Ukulungiswa kwempazamo yediode. Kukho iziphene ezifana nokuvula iindlela kunye neesekethe ezimfutshane, ezinokubangelwa kukugqithisa, okanye kunokubangelwa ukusetyenziswa kwexesha elide lokungaphumeleli. Fumana i-diode yokuhlaziya enexabiso elixhathisa amandla ombane angaphezu kwe-350V kunye nomsebenzi wangoku omkhulu kuno-0.5A, njenge-1N4004 1N4007, njl. 6. Ukungaphumeleli kwesekethe yokuqhubela phambili kwe-LED rhoqo. Kwiingcali ezifuna amava ahlobene ne-elektroniki kulolu hlobo lokungaphumeleli ukulungiswa, banokufumana abasebenzi bezobugcisa beZhuhai abavelisi ukuze balondoloze. Umenzi ugxile ekuveliseni ubuhlalu besibane se-LED. Ityebile ngamava. Kungcono ukubuyisela i-bead yesibane se-LED entsha emva kokungaphumeleli okulula okungentla.
