Isidingo sokuvikelwa kwamalambu omgwaqo e-LED
Ukushaywa kombani ukukhishwa kwe-electrostatic ngokuvamile okuthwala izigidi zamavolthi ukusuka emafwini kuya phansi noma kwelinye ifu. Ngesikhathi sokudlulisa, umbani udala izinkambu zikazibuthe emoyeni, udonse izinkulungwane zama-volts (okungukuthi, ama-surges) entanjeni kagesi futhi ukhiqize amaza omoya ahamba amakhilomitha angamakhulu. Lokhu kuhlasela okungaqondile ngokuvamile kwenzeka ezintanjeni ezingaphandle, njengezibani zomgwaqo. Izisetshenziswa ezifana namarobhothi neziteshi eziyisisekelo zikhipha ukukhuphuka. Imojula yokuvikela ukukhuphuka ibhekane ngqo nokuphazamiseka kokukhuphuka okuvela entanjeni yamandla ekugcineni kwesekhethi. Idlulisa noma imunce amandla okuhlinzwa, inciphise usongo lokwenyuka kwamanye amasekhethi asebenzayo, njengamayunithi wamandla e-AC/DC kuma-LED lighting fixtures.
Kumalambu omgwaqo we-LED, umbani udala ukukhuphuka okubangelwa intambo kagesi. Lokhu kunyuka kwamandla kudala ukukhuphuka kocingo, okungukuthi, igagasi elikhuphukayo. Ukuhlinzwa kudluliselwa ngokungeniswa okunjalo. Izwe langaphandle linokuhlinzwa. Igagasi lizodala ithiphu ku-sine wave kulayini wokudlulisa ongu-220V. Lapho ithiphu ingena ekukhanyeni komgwaqo, izolimaza isifunda sesibani somgwaqo we-LED.
Amalambu asemigwaqweni aseneminyaka eminingi ekhona. Kungani manje udinga ukuthola ukuvikeleka kombani kumalambu omgwaqo? Eqinisweni, izibani ze-sodium ezinomfutho ophezulu kanye nezibani zendabuko ze-mercury ezisetshenziswe esikhathini esidlule zenzelwe ama-high-pressure bulbs, anomphumela wokuvikela umbani. Eminyakeni yamuva, izibani ze-LED ziye zanda kakhulu. Izibani ze-LED zidinga i-voltage encane yokuhlinzeka. Ngokuvamile, ukunikezwa kwamandla kusetshenziswa ukuguqula amandla e-AC abe amandla e-DC. Lokhu kwenza isibani somgwaqo we-LED ngokwaso singabi naso isivikelo sombani, ngakho-ke sidinga ukuklanywa amalambu omgwaqo. Imojula yokuvikela umbani.
Ukubaluleka kokuvikelwa kombani wesitaladi kunqunywa umqondo wesikhathi sokukhokha. Njengoba isibani somgwaqo i-LED sibiza cishe ngokuphindwe kabili kunesilambu somgwaqo esivamile, uhulumeni unesamba esikhulu sokutshala imali ekuqaleni kokuthenga. Ngakho-ke, kuyadingeka ukonga kancane kancane izindleko ngokulondoloza izindleko zikagesi ngesikhathi sokusebenza. Ngakho-ke, impilo yesibani se-LED ibaluleke kakhulu. Uma ilambu le-LED lingazange libuyise izindleko futhi liphukile phakathi nesikhathi sokubuyisela utshalomali, kuzobiza imali ukuyilungisa. Izindleko zabasebenzi zokunakekela zibiza ngokuphindwe kabili kunokufakwa. Ngakho-ke, ngenkathi ye-LED, ukufeza umphumela wokulondoloza amandla nokulondoloza imali, kuyadingeka ukuqinisekisa ukuthi ubude bayo bokuphila bungakwazi ukufinyelela okulindelekile, okungukuthi, umkhiqizo unesikhathi eside sokuphila. Ukuze kuzuzwe ukonga izindleko kanye nokuqinisekisa ukuthi izibani zasemgwaqweni azilinyazwa ngesikhathi sokuthola kabusha utshalomali, ukwethembeka kudinga ukwanda. Lokhu kudinga imojula yokuvikela umbani yesibani somgwaqo se-LED ukuze kwandiswe umnotho.
Ngokufika kwenkathi ehlakaniphile, izibani zasemgwaqweni ezihlakaniphile zingene ezimweni ezisebenzayo zohlelo lokusebenza. Isibani somgwaqo esihlakaniphile simele ukukhanya komgwaqo okwenza isibani somgwaqo sivulwe futhi sicishwe ku-inthanethi Ekude Yezinto, futhi singalungisa umbala nokukhanya kwesibani somgwaqo. Uma kuqhathaniswa, amadivayisi ahlakaniphile anemisebenzi eminingi, futhi ukwethembeka kufanele kuthuthukiswe. Izinkinga zokuphepha zibalulekile. Ukuvikela umbani, ukuvikela umbani nemisebenzi yokuphepha kufanele kuhlangatshezwane nayo ngesikhathi esifanayo.
