Umehluko phakathi kwezibani ze-Halogen neze-LED
I-Pengantar
Ezikhathini zanamuhla, ukukhanya okwenziwayo kuyisici esibalulekile empilweni yansuku zonke. Ubuningi bezinketho zobuchwepheshe bokukhanyisa buvumela abathengi ukuthi bakhethe ngokusekelwe ezidingweni zabo kanye nezintandokazi zabo. Phakathi kwezinhlobo eziningi zezibani, izibani ze-halogen kanye ne-LED (Light Emitting Diode) zivelele njengezinketho ezimbili ezidumile. Nakuba zombili zinezinzuzo zazo, umehluko oyisisekelo phakathi kwazo ungaba yisici esinqumayo ezinqumweni zokuthenga. Lesi sihloko sizohlola umehluko phakathi kwezibani ze-halogen kanye ne-LED ngokujulile kusukela emibonweni eyahlukene, okuhlanganisa ukusebenza kahle kwamandla, impilo yezibani, ikhwalithi yokukhanya, umthelela wemvelo, kanye nezindleko.
Umlando kanye Nezimiso Zokusebenza
Izibani zeHalogen
Izibani ze-halogen zakhiwa ngo-1955 njengokuthuthukiswa kwezibani zendabuko ze-incandescent. Zisebenza ngesimiso esifanayo nezibani ze-incandescent. Intambo ye-tungsten isebenza ekushiseni okuphezulu kakhulu, ikhiqiza ukukhanya ngokushisa intambo ize ikhanye. Ezibani ze-halogen, intambo ifakwa ku-capsule encane equkethe igesi ye-halogen, njenge-iodine noma i-bromine. Le gesi isiza ukwandisa impilo yentambo ngokwenza kube lula umjikelezo we-halogen-tungsten, lapho i-tungsten ephuma kuntambo iphinda ibekwe kuntambo, okunciphisa ukuguguleka.
Isibani se-LED
Ukukhanya kwe-LED kuyindlela entsha yesimanje kakhulu, enentuthuko enkulu eminyakeni eyishumi edlule. Ama-LED akhiqiza ukukhanya ngenqubo ye-electroluminescence. Lapho ugesi udlula ku-semiconductor, ama-electron ezintweni ze-semiconductor ayahamba futhi ashayisane "nezimbobo" ezishajelwe kahle, ezikhiqiza ama-photon, noma ukukhanya. Lobu buchwepheshe buvumela ukuguqulwa kwamandla kagesi abe ukukhanya ngokusebenza kahle kakhulu futhi ngaphandle kwesidingo se-filament ye-incandescent.
Ukusebenza Kwamandla
Omunye wemimehluko ephawulekayo phakathi kwezibani ze-halogen nezibani ze-LED ukusebenzisa kahle amandla. Izibani ze-LED zisebenza kahle kakhulu kunezibani ze-halogen.
Izibani zeHalogen
Izibani ze-halogen, njengezibani ze-incandescent, zikhiqiza ukukhanya ngokushisa i-filament kuze kufike ekushiseni okuphezulu. Ngeshwa, le nqubo ayisebenzi kahle kakhulu, njengoba iningi lamandla asetshenziswayo liguqulwa libe ukushisa, hhayi ukukhanya. Ngokuvamile, izibani ze-halogen zisebenza kahle cishe ngama-lumens ayi-10-20 nge-watt ngayinye.
Isibani se-LED
Ngokuphambene nalokho, ama-LED asebenza kahle kakhulu ekuguquleni amandla kagesi abe ukukhanya. Izibani ze-LED zingakhiqiza phakathi kwama-lumens angu-80 no-100 nge-watt ngayinye, noma ngaphezulu kwemikhiqizo yakamuva. Lokhu kusho ukuthi ukusebenzisa izibani ze-LED kunganciphisa ukusetshenziswa kwamandla ngo-75% kuya ku-80% uma kuqhathaniswa nezibani ze-halogen.
Impilo Yesibani
Ukuphila kwezibani kuyisici esibalulekile esivame ukucatshangelwa ngabathengi. Izibani ezihlala isikhathi eside azidingi ukushintshwa njalo futhi azidingi ukunakekelwa okuningi.
Izibani zeHalogen
Izibani ze-halogen ngokuvamile zihlala isikhathi eside kunezibani ze-incandescent, kodwa zisezifushane uma ziqhathaniswa nama-LED. Ngokuvamile, izibani ze-halogen zingahlala amahora angaba ngu-2.000 kuya ku-3.000 okusetshenziswa.
Isibani se-LED
Izibani ze-LED ziphila isikhathi eside kakhulu, zisebenza amahora aphakathi kuka-15.000 no-50.000. Ezinye izibani ze-LED ezisezingeni eliphezulu zingahlala amahora afinyelela ku-100.000. Lokhu kusho ukuthi isibani esisodwa se-LED singahlala iminyaka, ngisho nokusetshenziswa kwansuku zonke okuphindaphindiwe.
Ikhwalithi Yokukhanya
Ikhwalithi yokukhanya iyipharamitha ebalulekile, ikakhulukazi kwezinye izinhlelo zokusebenza njengokukhanya kwangaphakathi, lapho umbala kanye nokuqina kokukhanya kudlala indima enkulu.
Izibani zeHalogen
Izibani ze-halogen zaziwa ngokukhiqiza ukukhanya kwemvelo nokufudumele, okufana nokukhanya kwe-incandescent. I-Color Rendering Index (CRI) yezibani ze-halogen ngokuvamile iphakeme kakhulu, isondela ku-100, okusho ukuthi imibala yezinto ezikhanyisiwe ibonakala inembe kakhulu. Kodwa-ke, ukukhanya kwe-halogen spectrum kuvame ukuthambekela kokuphuzi, okungaba yintandokazi ethile yokukhanya kwemizwa.
Isibani se-LED
Izibani ze-LED zinokuguquguquka kokukhiqiza amazinga okushisa ahlukahlukene emibala, kusukela ekukhanyeni okufudumele kakhulu (cishe ama-2700K) kuya ekukhanyeni okupholile kakhulu (kufika ku-6500K noma ngaphezulu). Inkomba Yokunikeza Umbala yezibani ze-LED nayo iphakeme kakhulu, eziningi zisondela noma zidlula ama-90. Ubuchwepheshe be-LED besimanje bunqobe inkinga ye-color spectrum engalingani ngezinye izikhathi yamamodeli okuqala, okwenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza eziningi zokukhanyisa.
Umthelela Wezemvelo
Uma kucatshangelwa umthelela wemvelo, kunezinto eziningi okumele zicatshangelwe njengokusetshenziswa kwamandla, izinto ezisetshenziswayo, kanye nokukhishwa kwegesi ngesikhathi sokukhiqiza nokulahla.
Izibani zeHalogen
Nakuba izibani ze-halogen zingcono kunezibani ze-incandescent ngokusebenza kahle kwamandla, zisenomthelela omkhulu emvelweni ngenxa yokusebenzisa kwazo amandla amaningi. Ngaphezu kwalokho, izibani ze-halogen ziqukethe izinto ezidinga izinsiza ezibalulekile ukuze zikhiqize futhi azinazo izinketho eziningi zokusebenzisa kabusha.
Isibani se-LED
Izibani ze-LED zinobungani kakhulu nemvelo ngezindlela eziningana. Ukusetshenziswa kwamandla aphansi kusho ukukhishwa kwegesi ebamba ukushisa okuphansi okuvela ekukhiqizweni kwamandla. Ngaphezu kwalokho, izingxenye eziningi ze-LED zingasetshenziswa kabusha. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukukhiqizwa kwe-LED kuhilela izinto ezingavamile kanye nezinqubo eziyinkimbinkimbi, ngakho-ke kunemiphumela emvelweni ngesikhathi sesigaba sokukhiqiza okumele icatshangelwe.
Izindleko
Izindleko ziyisici esibalulekile ezinqumweni zabathengi, futhi lezi zindleko azihlanganisi nje kuphela intengo yokuthenga kodwa nezindleko zokusebenza njengokusetshenziswa kwamandla kanye nokushintsha izibani.
Izibani zeHalogen
Izibani ze-halogen ngokuvamile zishibhile ukuzithenga kunezibani ze-LED. Lokhu kungaba ukonga kokuqala kwabathengi. Kodwa-ke, ngokuphila isikhathi esifushane kanye nokusebenza kahle kwamandla okuphansi, izindleko zokusebenza kwezibani ze-halogen ziphakeme kakhulu kunezibani ze-LED.
Isibani se-LED
Intengo yokuqala yezibani ze-LED ivame ukuba phezulu, kodwa izindleko zazo zokusebenza ziphansi kakhulu ngenxa yokusebenza kahle kwamandla aphezulu kanye nokuphila isikhathi eside. Ngokuhamba kwesikhathi, izibani ze-LED cishe zihlala zingabizi kakhulu ukuzisebenzisa kunezibani ze-halogen. Ngaphezu kwalokho, abanye abakhiqizi banikeza iziqinisekiso ezinde ezibani ze-LED, okwengeza inani kubathengi.
Isiphetho
Kusukela ezicini ezahlukahlukene okuxoxwe ngazo, kusobala ukuthi izibani ze-LED zinikeza izinzuzo eziningi kunezibani ze-halogen maqondana nokusebenza kahle kwamandla, impilo yezibani, ukuguquguquka kwekhwalithi yokukhanya, kanye nomthelela emvelweni. Nakuba izindleko zokuqala zezibani ze-LED ziphakeme, ukonga amandla kwazo kanye nokuphila isikhathi eside kuzenza zibe ukukhetha okungabizi kakhulu ngokuhamba kwesikhathi.
Kodwa-ke, izibani ze-halogen zisasebenza ngokukhethekile lapho kudingeka khona ikhwalithi yokukhanya kwemvelo noma lapho izindleko zokuqala ziyinto ebaluleke kakhulu. Ngakho-ke, ukukhetha phakathi kwezibani ze-halogen neze-LED kufanele kusekelwe ezidingweni ezithile, okuthandwa nguwe, kanye nokucatshangelwa kwezomnotho kwesikhathi eside.
Amabhalbhu e-halogen kanye ne-LED anendawo yawo ezweni lokukhanya kwesimanje, futhi ukuqonda umehluko phakathi kwalokhu kungasiza abathengi ukuthi benze izinqumo ezinolwazi oluthe xaxa ezifanelana kahle nezidingo zabo.
