Izibani ze-LED Zivame Bona Amaphutha kanye Nezindlela Zokulungisa

Indlela yokulungisa ukukhanya kwe-LED? UZhuhai ufundisa wonke umuntu ukuthi afunde ukukwenza. Amaphutha alula we-LED angakwazi nokuzilungisa ngokwawo. Izibani ze-LED zihlukile kunezibani zangaphambili ze-incandescent. Amalambu e-incandescent empeleni aphukile. Ngokuyisisekelo, ama-tungsten filaments ashiswa. Izibani ze-LED zihlukile. Amalambu e-LED akhiwe ngamasekethe e-LED drive kanye nobuhlalu belambu le-LED. Iningi lezibani ze-LED zingalungiswa, kodwa intengo yezibani ze-LED ayiphezulu. Inqwaba yenqwaba, ngakho-ke akekho ochwepheshe ekulungiseni izibani ze-LED, intengo iphakeme, abanye abazimisele ukulungisa, intengo iphansi, izindleko zabasebenzi ziphansi kakhulu, ngakho-ke zingalungiswa kuphela ngabasebenzisi. Ungawalungisa kanjani amalambu e-LED njengabasebenzisi abajwayelekile? Kunezizathu eziningi zokuhluleka kwezibani ze-LED, kodwa kukhona ukwehluleka okulula. Kutuswa ukuthi abasebenzisi bangazama ukuzilungisa futhi bazilolonge njengokuphrakthiza. Izibani ze-LED zivame ukubona amaphutha kanye nezindlela zokuzilungisa 1. Ubuhlalu besibani se-LED bulimele. Lokhu ukwehluleka okuvamile. Ngokuvamile, lapho ubuhlalu besibani se-LED bushiswa, kuzoba namabala amnyama ebusweni. Ukuqaphela ngokucophelela kungahlukaniswa. Ukuze wenze lokhu kulungiswa kwephutha, udinga ukuhlomisa insimbi yesosha. Kodwa kuthiwani uma bungekho ubuhlalu besibani se-LED? Ingasebenzisa 150 ωUkumelana kwesokunxele nesokudla kungena esikhundleni, uma umshayeli wamanje ongashintshi angaxhunywa ngokuqondile. 2. Ukuhluleka kokuhlunga kwamandla. Isibani se-LED esilula ngokuvamile silungisa ugesi we-AC ngokubekezelela nokwehlisa ingcindezi, bese sinika amandla ubuhlalu besibani se-LED ngokuhlunga kwe-capacitor. Uma ukwehluleka kwe-capacitor yesihlungi kuzobangela ukuthi i-voltage ingazinzi, i-voltage ye-DC iphansi, okwenza ukukhanya kwe-LED kube mnyama. Linganisa umthamo we-capacitor yokuhlunga ngefayela le-multimeter capacitor. Uma iphutha likhulu, iphutha likhulu kune-30%. Kusho ukuthi amandla anciphile. Thola ukumelana nomthamo kanye nomthamo omkhulu kunokulingana nepharamitha ye-capacitor. 3. Imojula yokudonsela phansi ukumelana nomthamo yonakele. I-capacitor resistance drop module iqukethe i-capacitor capacitor kanye nokumelana okufanayo. Ingasetshenziselwa ukukala ukuthi amandla ayo kanye nokumelana kungalimala yini. 4. Buyela. Hlukanisa ukukhanya kwe-LED futhi uhlole ukuthi kukhona yini ukunqanyulwa kwentambo yangaphakathi ne-output. Uma kunjalo, sebenzisa i-soldering iron kagesi ukuyilungisa. 5. Ukulungisa iphutha le-diode. Kunamaphutha njengokuvula imigwaqo nama-short circuits, okungase kudalwe wukugeleza ngokweqile, noma kudalwa wukungasebenzi isikhathi eside. Thola i-diode yokulungisa enevelu eliphikisana ne-voltage ehlehlayo engaphezu kuka-350V kanye nesimanje esisebenzayo esikhulu kuno-0.5A, njenge-1N4004 1N4007, njll. 6. Ukwehluleka kwesekethe ye-LED yamanje yokushayela njalo. Ochwepheshe abadinga ulwazi oluthile oluhlobene ne-elekthronikhi kulolu hlobo lokwehluleka ukulungisa, bangathola abasebenzi bezobuchwepheshe babakhiqizi be-Zhuhai ukuze banakekele. Umkhiqizi ugxile ekukhiqizeni ubuhlalu besibani se-LED. Icebile ngokuhlangenwe nakho. Kungcono ukufaka esikhundleni ubuhlalu besibani esisha se-LED ngemuva kokwehluleka okungenhla.
