Ehlobo, ukuduma kwezulu kuvame kakhulu, ukushaywa kombani kuwukuphuma kukagesi okuvamise ukuthumela izigidi zamavolthi ukusuka efwini kuya phansi noma kwelinye ifu. Njengoba uhamba, umbani udala inkambu kazibuthe emoyeni edala izinkulungwane zama-volts (aziwa ngokuthi ama-surges) ezintanjeni zikagesi kanye namandla akhona afinyelela amakhulu amamayela kude. Lokhu kuhlasela okungaqondile kuvame ukwenzeka ngaphandle ezintanjeni zikagesi eziveziwe, njengamalambu omgwaqo. Imishini efana namarobhothi neziteshi eziyisisekelo zithumela amagagasi. Imojula yokuvikela ukukhuphuka ibhekane ngqo nokuphazamiseka kokukhuphuka okuvela entanjeni yamandla ekugcineni kwesekhethi. Idlulisa noma imunce amandla okugeza ukuze kuncishiswe usongo lokukhuphuka kwamanye amasekhethi asebenzayo, njengamayunithi wamandla e-AC/DC kumishini yokukhanyisa ye-LED.
Ezibani zasemgwaqweni ze-LED, umbani udala ukukhuphuka okubangelwa intambo yamandla. Lokhu kunyuka kwamandla kudala i-shockwave ocingweni, okusho ukuthi, i-shockwave. I-surge isakazwa yilokhu kufakwa. Umhlaba uyanda. Igagasi lizokhiqiza ithiphu ku-sine wave eduze komugqa wokudlulisela ongu-220 v. Lapho ithiphu ingena esibani somgwaqo, izolimaza isifunda sesibani somgwaqo we-LED.
Ngakho-ke, ukuvikelwa kombani kwezibani ze-LED zomgwaqo kuzozuzisa impilo yabo yesevisi, okudingekayo okwamanje.
Ngakho-ke lokhu kudinga ukuthi senze umsebenzi omuhle wokuvikela umbani wamarobhothi e-LED, ngaphandle kwalokho kuzothinta ukusetshenziswa kwawo okuvamile, okuholela esiphithiphithini sezimoto. Ngakho-ke ungakwenza kanjani ukuvikelwa kombani kwamarobhothi e-LED?
1.Faka induku yombani yamanje ekhawula phezu kwensika yesibani sesignali yethrafikhi ye-LED
Ukuxhunywa okuthembekile kukagesi kanye nemishini kufanele kwenziwe phakathi kwengaphezulu lesekelo kanye nesisekelo senduku yombani ekhawulayo yamanje. Khona-ke, ukusekelwa kungenziwa phansi noma kuxhunywe kunethiwekhi yomhlabathi yokusekela ngokwayo ngensimbi eyisicaba. Ukumelana okuphansi kufanele kube ngaphansi kuka-4 ohms.
2. Isivikeli se-overvoltage sisetshenziswa njengesivikelo sokuphakelwa kwamandla ekuholeni kwesiginali yethrafikhi ye-LED nokulawula isignali umthombo wemishini nogesi.
Kufanele sinake ukungangeni kwamanzi, umswakama-umswakama, uthuli kanye nentambo yethusi yesivikeli se-overvoltage ixhunywe nokhiye wokumisa uhlaka lomnyango ngokulandelanayo, futhi ukumelana nokubekwa phansi kungaphansi kwenani elishiwo lokumelana.
3. Ukuvikelwa phansi
Ukuze uthole umgwaqo ojwayelekile, insika yayo kanye nokusatshalaliswa kwemishini yangaphambili kuhlakazekile, ngakho-ke sifuna ukufeza iphuzu elilodwa lokubeka phansi kuzoba nzima. Ngakho-ke ukuze kuqinisekiswe ukuthi amarobhothi e-LED asebenza ngokuyisisekelo kanye nokuvikela umuntu, kuphela ensikeni ngayinye engaphansi kokusetshenziswa komzimba ophansi oqondile oshiselwe esakhiweni senethiwekhi, okungukuthi, imodi yokubeka phansi enamaphuzu amaningi ukuze igagasi elingenayo lidedele kancane kancane kanye neminye imibani. izidingo zokuvikela.
