Kufanele ushintshe ama-halogen ngama-LED?
Ama-LED ahlinzeka ngokukhanya okuqinile ngaphandle kokufaka ingcindezi enkulu ohlelweni lukagesi lwemoto. Ngokokuqala ngqa, lolu hlobo lwesibani, olwenzelwe ukufakwa kumalambu emoto, lwavela kumamodeli we-premium abizayo eminyakeni eminingana edlule. Eminyakeni yokuqala ngemuva kwalokho, abanikazi bezimoto "ezejwayelekile" babheka ngomona labo abahlonyiswe ngama-LED futhi baphupha ukuthi izimoto zabo zinamalambu afanayo e-LED.
Ngemuva kweminyaka embalwa, ama-bulb aqala ukuvela ezitolo zezingxenye zezimoto, futhi manje wonke umuntu ukhululekile ukuthenga isethi yama-LED ukuhlomisa amalambu emoto abo. Ikhithi enjengale ibifakwe emshinini wokuhlola ukuze kuqinisekiswe ukuthi umqondo omuhle kakhulu lowo. Udaba belungagcini ngokufakwa kwabo, kepha futhi nokuqhathaniswa nezinye izinhlobo zamalambu e-halogen. IToyota 4Runner yango-1996 yakhethwa njengemoto yokuhlola, efaka ukusetshenziswa kwama-H4 halogen bulb kumalambu amafushane, okunikeza ithuba elihle kakhulu lokuhlolwa.
Akunakwenzeka ukungabaza ukuphakama okuphezulu kwalolu hlobo lwesibani sokukhanya. Kodwa-ke, lesi akuyona into ebaluleke kakhulu ekukhanyeni kwezimoto. Ipharamitha ebaluleke kakhulu ububanzi bendawo yokukhanya ekhanyayo. Lesi yisizathu sokuqhathanisa ukuthi yimaphi ama-bulb angcono ekukhanyiseni umgwaqo. Ama-LED angahle angakhanyi ngokukhanya okukhanyayo njengokujwayelekile.
Izibani ze-halogen zinesimiso esifanayo sokusebenza njengezibani ezivamile ze-incandescent. Umehluko kuphela ukuthuthukiswa kobuchwepheshe. I-flask yengilazi iqukethe igesi yeyodwa yama-halogens amabili - i-bromine noma i-iodine. Lokhu kukuvumela ukuthi ukwandise izinga lokushisa lokushisa kwe-spiral, kanye nempilo yayo yesevisi. Umphumela uba ukwanda okuphawulekayo kokukhanya kwalolu hlobo lwesibani.
Ukwandisa amandla wezibani ze-LED, abakhiqizi bafaka isibonakaliso se-aluminium parabolic ekwakhiweni kwabo, okwandise kakhulu ukugxila kokukhanya. Ngokombono osebenzayo, ama-LED anezinzuzo eziningi ngaphezu kwama-halogen ajwayelekile. Okokuqala, lokhu kuyizinga elikhulile lokukhanya, kanye nempilo yesevisi ende. Ngaphezu kwalokho, babonakala ngezinga eliphansi lokusetshenziswa kukagesi.
Ngaphandle kokuthi izibani ze-LED zinezinkinga eziningi, zingcono kakhulu kunezibani ezijwayelekile ze-halogen. Kodwa-ke, ngeke zibe indawo ephelele yama-halogen ngenxa yesibani esifushane sokukhanya nokusabalalisa okungabalulekile.
