Ehlobo, iziphepho zivamile kakhulu, umbani ukhipha ama-electrostatic ngokuvamile athumela izigidi zama-volts kusuka efwini kuya phansi noma kwelinye ifu. Njengoba uhamba, umbani udala insimu kagesi emoyeni edala izinkulungwane zama-volts (aziwa ngokuthi ama-surges) emigqeni kagesi kanye nogesi obangelwayo oqhele ngamakhilomitha amaningi. Lokhu kuhlasela okungaqondile kuvame ukwenzeka ngaphandle emigqeni kagesi eveziwe, njengezibani zomgwaqo. Imishini efana nezibani zomgwaqo kanye neziteshi eziyisisekelo ithumela amagagasi. Imojuli yokuvikela ama-surge ibhekene ngqo nokuphazamiseka kwama-surge kusuka emugqeni kagesi ekugcineni kwesekethe. Idlulisela noma imunca amandla ama-surge ukuze inciphise usongo lwama-surge kwezinye izifunda ezisebenzayo, njengeyunithi yamandla e-AC/DC emishinini yokukhanyisa ye-LED.
Kumalambu omgwaqo e-LED, umbani udala ukukhuphuka okubangelwa yintambo kagesi. Lokhu kukhuphuka kwamandla kudala ukushaqeka entanjeni, okusho ukuthi, ukushaqeka. Ukushaqeka kudluliselwa yilokhu kungeniswa. Umhlaba laphaya uyanda. Igagasi lizokhiqiza i-tip ku-sine wave eceleni komugqa wokudlulisela we-220 v. Uma i-tip ingena esibanini somgwaqo, izolimaza isekethe yesibani somgwaqo se-LED.
Ngakho-ke, ukuvikelwa kombani kwezibani zasemgwaqweni ze-LED kuzozuzisa impilo yazo yokusebenza, okudingekayo njengamanje.
Ngakho-ke lokhu kudinga ukuthi senze umsebenzi omuhle wokuvikela izibani zethrafikhi ze-LED, ngaphandle kwalokho kuzothinta ukusetshenziswa kwazo okuvamile, okuholela ekuphazamisekeni kwethrafikhi. Ngakho-ke singakuvikela kanjani ukukhanyisa izibani zethrafikhi ze-LED?
1. Faka induku yombani ekhawulela amandla kagesi ensikeni yesibani sesignali yethrafikhi ye-LED
Ukuxhumana okuthembekile kukagesi nokwemishini kumele kwenziwe phakathi kwengxenye ephezulu yokusekela kanye nesisekelo senduku yombani ekhawulelayo yamanje. Ngemuva kwalokho, ukwesekwa kungasekelwa noma kuxhunywe kunethiwekhi yomhlabathi yokusekela ngokwayo ngensimbi eyisicaba. Ukumelana komhlabathi kumele kube ngaphansi kwama-ohms angu-4.
2. Isivikelo se-Overvoltage sisetshenziswa njengesivikelo sokunikezwa kwamandla esiholwa isibani sesignali yethrafikhi ye-LED kanye nomthombo wokulawula isignali wemishini nokagesi
Kufanele sinake ukuthi i-waterproof, umswakama, uthuli kanye nentambo yethusi yesivikelo se-overvoltage ixhunywe kukhiye wokufaka isisekelo wohlaka lomnyango ngokulandelana, futhi ukumelana nesisekelo kungaphansi kwenani lokumelana elichaziwe.
3. Ukuvikelwa komhlabathi
Ukuze kube nokuhlangana okujwayelekile, ukusatshalaliswa kwemishini yayo yezinsika kanye neyangaphambili kuhlakazekile, ngakho-ke sifuna ukufeza iphuzu elilodwa lokubeka phansi kuzoba nzima. Ngakho-ke ukuze kuqinisekiswe ukuthi izibani zethrafikhi ze-LED zisebenza ukubeka phansi kanye nokuvikela komuntu siqu, kuphela kunsika ngayinye engezansi ukusetshenziswa komzimba wokumisa oqondile ohlanganisiwe esakhiweni senethiwekhi, okungukuthi, imodi yokumisa phansi enamaphuzu amaningi ukuze igagasi elizayo likhululeke kancane kancane kanye nezinye izidingo zokuvikela umbani.
