Asalin samar da wutar lantarki na LED yana da nau'o'i masu mahimmanci guda uku: ƙananan batura, ƙwayoyin hasken rana, da wutar lantarki na kasuwar sadarwa. Ko da wane nau'in wutar lantarki na asali da aka karɓa, abin da ake bukata don canjin wutar lantarki ya gamsu da LED. Wannan nau'in da'irar canjin wuta gabaɗaya tana nufin da'irar tuƙi na LED. A cikin tsarin samar da wutar lantarki na hasken rana, ana buƙatar batura ko ultra-supercapacitors don adana makamashin hasken rana. Lokacin yin haske da daddare, ana fitar da batura ko manyan capacitors ta hanyar sarrafa da'ira don kunna da'irar tuƙi na LED. Ƙungiyar makamashin hasken rana da makamashin iska da kuma LED shine hasken shekara guda na LED. Zai kawo haske ga talauci da yankuna masu nisa na duniya ta uku, kuma bari hasken kore mai ɗaukaka ya haskaka kowane lungu na duniya. Samar da wutar lantarki na LED da ƙirar ƙirar su ta hanyar tuƙi 1. Da'irar direban LFD tare da ƙarancin wutar lantarki na DC 1. Lokacin da ƙarfin shigarwar ya fi ƙarfin LED, lokacin da ƙarfin shigarwar ya fi ƙarfin lantarki na LED ko LED kirtani Antihypertensive regulator. (1) Mai daidaita layin layi na layi shine mai jujjuyawar antihypertensive DC-DC. Yawancin masu sarrafa layin da aka karɓa ta hanyar da'irar kebul na LED sune ƙananan-ƙaramar bambancin masu kayyadewa (LDO). Ƙarfin shine cewa babu buƙatar kayan aikin inductance, adadin abubuwan da ake buƙata kaɗan ne, EMI rashin haihuwa yana faruwa, kuma raguwar ƙarfin wutar lantarki nasa ya fi ƙarfin rage ƙarfin fiye da ƙarfin. Duk da haka, idan aka kwatanta da mai sarrafa nau'in canji, asarar wutar lantarki na LDO har yanzu yana da tsufa, kuma ingancin yana da ƙasa. Lokacin da LDO ke tafiyar da 350mA ko sama da igiyar LED mai ƙarfi, yana buƙatar ƙarawa da radiator. (2) Canja-ƙarfin ƙarfin lantarki (buck) stabilizer yana dogara ne akan mai canzawa -type antihypertensive regulator na guda-chip-specific IC. Yawancin juzu'in mai sarrafa hawan jini ya wuce 1MHz, wanda ke sa abubuwan da ke waje su yi ƙanƙanta. Entangle yana da ƙananan ƙananan, tare da inganci fiye da 90%. Duk da haka, irin wannan nau'in na'ura zai haifar da canza murya, kuma akwai matsalar EMI. Hoto 1 yana nuna da'irar haɓakar haɓakar 3WLED dangane da Zetex ZXSC300. RCS anan ita ce juriya na isar da wutar lantarki. Ƙarƙashin ƙarfin shigarwa na 6V, LED na yanzu ya kai 1.11A.ZXSC300 don karɓar marufi 5 SOT23. Wutar wutar lantarki ta LED da ƙirar da'irar tuƙi ta asali a halin yanzu tana da masu taswirar antihypertensive guda-chip ICs don sauya MOSFET (Q1) da diode antihypertensive (D1). 2. Lokacin da ƙarfin shigarwar ya yi ƙasa da ƙarfin lantarki na LED, lokacin da ƙarfin shigarwar ya yi ƙasa da ingantaccen ƙarfin lantarki na LED ko kirtani na LED, LED ɗin yana buƙatar haɓaka da'irar wutar lantarki. Akwai nau'i biyu na booster Converter a cikin wadannan iri biyu. (1) Mai jujjuya matsa lamba kai tsaye A cikin cin zarafin wayar hannu, ana yawan amfani da da'irar direban mai kunna wuta ta LED. Ana amfani da mai canza canji na nau'in inductance a matsayin kirtani na LED ɗaya ko fiye da abun da ke ciki na LED, kuma halin yanzu na kowane LED daidai yake. Idan akwai hanyar LED a cikin igiyar LED, sauran LEDs zasu fita. Hoto na 2 yana nuna da'irar firikwensin firikwensin LED. Zaren LED ya ƙunshi NSPW500BS farin haske Ledled fitilu na NSPW500BS na 8 Japan Asia Chemical Corporation. A ƙarƙashin ƙarfin shigarwar 4V, halin yanzu na kowane LED yana kusan 25mA akan kowane LED. Wutar wutar lantarki ta LED da ƙirar da'irar tuƙi ta asali galibi tana haɓaka mai sarrafa IC, kuma an haɗa bututun sauyawa a cikin guntu. (2) The switch capacitor (charge pump) boost Converter canza capacitor ƙarfin lantarki Converter, wato cajin famfo. IC na musamman na famfo mai caji yana da ginanniyar juyawa, wanda aka haɗa zuwa 1 ko biyu 1 μF's caji capacitor. Akwai 1 ×, 1.5 ×2 ×A cikin 'yan shekarun nan, ya nuna 1.33 ×(4/3 sau) da 4 ×abin koyi. Lokacin da ƙarfin fitarwa yana kusa da ƙarfin shigarwa, famfon caji baya buƙatar ƙara ƙarfin lantarki, wato, a 1 ×Misali. Lokacin da ake buƙatar matsa lamba, canza zuwa 1.5 ×Ko wasu abubuwa. Da'irar famfo na caji na iya fitar da tsararrun LED, ko LED ɗaya kaɗai.
