I-Xenon noma i-LED: yiziphi izibani ezingcono?
- I-Xenon noma ama-LED ama-bulb? Lo mbuzo uzohlala unempikiswano phakathi kochwepheshe be-automotive optics. Kokubili i-xenon ne-LED bathole ukuzethemba ngenxa yezinzuzo zabo ezingenakuphikwa. Izibani ze-Xenon zivele ngaphambi kwesikhathi kune-LED, kodwa zingumncintiswano omuhle emakethe.
Ubuchwepheshe balezi zinhlobo ezimbili zezibani zisebenza ngokuhlukile, zihluke komunye nomunye kudivayisi, ngakho-ke akulungile ukuziqhathanisa ngokuqondile. Okokuqala, sizocabangela isimiso sokusebenza kwe-xenon kanye nezibani ze-LED, izinzuzo eziyinhloko, ubuthakathaka, futhi uziqhathanise ngokuya ngemingcele eyinhloko yabanikazi bezimoto.
Ama-autolamp e-LED abhekwa njengemithombo yokukhanya efakwe izingxenye ezonga amandla ezisebenza kahle kakhulu nempilo ende yesevisi. Umgomo wokusebenza kwelambu elinjalo liqukethe izinguquko eziningi ukuze kuqinisekiswe ukukhazimula kwama-emitters afakwe ekwakhiweni kwawo. Lapho uhlinzeka nge-voltage esisekelweni, kuqala ukuya kumshayeli, oshayela i-voltage efanayo efomini elamukelekayo lamalambu e-LED.
Okokuqala, i-voltage eshintshanayo isetshenziswa ebhulohweni le-diode, lapho ilungiswa khona kancane. Bese uya esitsheni se-electrolytic, esiklanyelwe ukushelela ama-ripples. Ngaphezu kwalokho, i-voltage elungiswe ngokugcwele inikezwa isilawuli esilawula ukusebenza kwesibani se-LED. Kusuka kumojula ye-elekthronikhi, iya ngqo kuma-LED ngokusebenzisa i-pulse transformer.
Amalambu emoto e-LED afanele ukuma, amalambu aphansi naphezulu, amajika, amalambu e-trunk, amalambu angaphakathi, ngisho namalambu edeshibhodi. Indawo ngayinye yokukhanyisa inezici zayo zobuntu ekukhethweni kwezibani, okubandakanya isisekelo, ubukhulu obuphelele, ukukhanya okukhanyayo, izinga lokushisa elikhanyayo, i-voltage yamapayipi.
Amalambu e-Xenon ayimithombo yokukhanya ekhipha igesi enikeza ukukhanya okukhanyayo okuphezulu, okuqinisekisa ukuphepha kubashayeli emgwaqeni ebusuku kanye nezimo zezulu ezimbi. Izibani ziyi-flask equkethe umhwamuko we-mercury kanye nengxube yamagesi angasebenzi agcwele i-xenon.
Kukhona futhi ama-electrode amabili e-flask, phakathi kwawo, ngosizo lweyunithi yokuthungela, okungukuthi ukunikezwa kwe-pulse enamandla ngaphansi kwe-voltage engu-25000 V, i-arc kagesi, insimu ye-electromagnetic. Ukwenza kusebenze ukusha kwegesi ye-xenon kunikezwa ngenxa ye-ionization yama-molecule egesi kanye nokunyakaza kwawo. Ngemuva kokuthi iyunithi yokuthungela inikeze ukunikezwa kwamanje ku-voltage ephezulu futhi ukukhanya kwesibani kucushiwe, ukunikezwa okuqhubekayo kwamanje kuyadingeka, okugcina ukushisa. Lesi yisimiso esiyisisekelo sokusebenza somthombo wokukhanya we-xenon, okuzokuvumela ukuthi uthole ukubonakala okuphezulu ezimweni ezahlukene zokusebenza.
Ukuqina. Ukuphila kwenkonzo ye-LED optics kufinyelela amahora angu-50 wokusebenza okuqhubekayo: izibani ezinjalo azishisi. Kulabo abangachithi isikhathi esiningi emgwaqeni ebusuku, lezi zibani zizohlala iminyaka emithathu.
Impilo yesevisi yesibani se-xenon ngokusebenza kahle nokusebenza kwemishini okungenani amahora angu-2000.
ukukhanya okukhiphayo. Amalambu e-LED, ngokungafani nama-xenon nama-bi-xenon, akhiqiza ukukhanya okukhudlwana okukhanyayo futhi anikeze ukukhanya okuqondisayo, kuyilapho engaziboni izimoto ezizayo. I-LED Optics ikhiqiza ukukhanya okumhlophe okukhanyayo kuze kufike ku-3500 Lumens. Njengomthetho, izibani ngokuvamile ezinokushisa kombala we-5-6 izinkulungwane ze-Kelvin (ezimhlophe noma ezimhlophe ezine-tint eluhlaza okwesibhakabhaka) zifakwe ezibani.
Izibani ze-Xenon zingaba nokushisa kombala ebangeni elibanzi kusuka ku-4-12 ayizinkulungwane ze-Kelvin. Ngokwekhwalithi, ukukhanya kwabo kuseduze nokukhanya kwemini futhi kubonwa kahle ngumuntu. Mayelana nokukhanya, kunjalo, i-xenon iyawina.
ukusebenza kahle kwamandla. Lapho esebenza, ama-LED adla inani elincane lamandla. Ukusebenza kahle okungenye yezinzuzo eziyinhloko zezibani ze-LED - azibangeli ukusetshenziswa kukaphethiloli ngokweqile futhi azilayishi inethiwekhi ebhodini. Ukusebenza kahle kwama-LED kufinyelela ku-80% - lokhu kungaphezu kwanoma yimuphi omunye umthombo wokukhanya. Ngenxa yalokho, amalambu e-LED anokonga amandla amaningi kunemithombo yokukhanyisa ye-xenon.
Okunye okungalungile kwezibani ze-xenon: zidinga amabhulokhi okushisa ukuze zisebenze: isibani esisodwa - ibhulokhi elilodwa (ukukhanya kwe-LED akudingi).
ikhwalithi. I-LED optics isebenza ngaphandle kwe-tungsten filament, engaphuka ngokudlidliza okuvamile. Ama-LED amelana nokudlidliza kahle futhi asebenza ngokwethembeka lapho ushayela emigwaqweni emibi. Ukuze uthole ukwethembeka okwengeziwe, zizungezwe i-epoxy resin sealant esobala.
Amalambu anamalambu e-xenon akhombise ukuthi aphephile emgwaqeni. Uma kwenzeka ukuphuka, izibani ze-xenon azicimi ngokushesha, kodwa ziyaqhubeka zikhanya isikhashana. Lokhu kunikeza umshayeli isikhathi sokudonsa ngokuphepha ebumnyameni. Uma isistimu yamandla ihluleka, ibhethri leyunithi yokuthungela izocisha ngokuzenzakalelayo futhi ivikele amalambu ekukhathaleni ngesikhathi sokuhlinzwa kwamandla.
Ukudlulisa ukushisa. Amalambu e-Xenon empeleni awashisi, kuyilapho amalambu e-LED angashisa kakhulu futhi adinga uhlelo oluhle lokupholisa. Ngakho-ke, ama-LED ashibhile anokupholisa okubi ngokuvamile awahlali isikhathi eside.
Nakuba i-LED ngokwayo ingashisi, ukuklanywa kwesibani, futhi ikakhulukazi ibhodi lapho ama-diode afakwe khona, akhiqiza ukushisa okukhulu. Ukushisa okudlulele kunciphisa impilo ye-optics, yingakho kubaluleke kakhulu ukuthi izibani zibe nokukhipha ukushisa okuhle;
Ukubumbana. Usayizi omncane wemithombo yokukhanya ye-LED ikuvumela ukuthi udale ngosizo lwabo ama-optics athuthuke kakhulu, athuthukisiwe.
Ukuhambisana kwemvelo. Ama-LED awaqukethe izinto ezilimaza imvelo njenge-mercury. Ayikhiphi imisebe ye-UV noma ye-IR futhi ingagaywa kabusha ekupheleni kwempilo yazo yesevisi.
Uma unquma ukufaka izibani ze-xenon emotweni yakho, kufanele wazi ukuthi kungcono ukushintsha imishini esiteshini sesevisi. Ukufakwa kwamamojula we-xenon noma we-bi-xenon kunama-nuances amaningi, ngoba imishini eyinkimbinkimbi isetshenziswa ngesikhathi sokufakwa. Isibonelo, amayunithi okuthungela, avame ukungangeni esibani sangaphambili futhi adinga ukukhwezwa ngaphandle.
Eqinisweni, ukudiliza nokufaka amalambu e-xenon amasha angeke kukuthathe isikhathi esiningi uma ungumakhenikha onolwazi, Ukuze wenze lokhu kukhohlisa, udinga ukuba nesethi egcwele yamathuluzi nezinto zokusebenza ezidingekayo, kanye nolwazi olukhethekile.
Phela, ukuklanywa kwezinhlobo eziningi zezimoto namamodeli wezimoto ngaphambi kokudilizwa nokushintsha izinto zokubona kuhilela ukususa ibhampa (ngaphambili). Esinye isimo esibalulekile soshintsho ukuthi izibani ze-xenon zishintshwa ngamabili - imfuneko. Ukuthi nje ama-shades alula wezibani avela kubakhiqizi abahlukene ahluke kakhulu komunye nomunye.
Njengoba sekushiwo kakade, ngezibani ze-LED, yonke into ilula kakhulu: vele ukhulule isibani esidala bese usifaka esisha. Imithombo yokukhanya ye-LED ayidingi imishini eyengeziwe, ayilayishi inethiwekhi ebhodini, futhi ngokufanele, asikho isidingo sokushintsha izibani.
Eminyakeni embalwa edlule, izibani ze-LED bezidingeka kakhulu phakathi kwabashayeli bezimoto. Sekuyisikhathi eside bayeka ukuba yisici sokuhlobisa noma ukukhanya okulula ku-cabin. Sekuyisikhathi eside zisetshenziswa njengomthombo wokukhanyisa ezibani ezingemuva ezigijimayo, futhi nasezikhanyisini ezicwilisiwe neziyinhloko ze-beam (ngaphezu kwalokho, ngempumelelo kakhulu).
Impilo yesevisi yezibani ze-LED iyinde impela, ama-LED azokwazi ukusebenza impilo yonke yemoto (okungcono). Kodwa-ke, amaphutha embonini ajwayelekile, ngakho-ke ama-optics anjalo angahluleka. Futhi ngokuvamile akuwona ama-LED ngokwawo ahlulekayo, kodwa ibhodi asebenza kulo. Ngenxa yezici zokuklama zamalambu e-LED, ngokuvamile akulula ukuwalungisa. Uma i-LED optics ingaphansi kokulungiswa, khona-ke izobiza imali eningi.
Ngokuphathelene ne-xenon, ngemva kweminyaka eminingana yokusetshenziswa, iqala ukufiphala, okuthinta ukukhanya kokukhanyisa. Ngenxa yalokho, kuzodingeka uthenge izibani ezimbili ezintsha, nazo ezingabizi.
Ngokombono wokuthuthukiswa kwe-automotive optics, ngokuhamba kwesikhathi, ukukhanya kwe-LED kuzoshintsha ngokuphelele imithombo yokukhanya ye-halogen ne-xenon. Okwamanje, izibani ze-LED zithuthuka njalo. Iyiphi i-xenon, yiziphi izibani ze-LED ezinezinzuzo nezingozi zayo. Iziphi ongazifaka - kukuwe ukuthi uzikhethe, ngokusekelwe ezidingweni zakho.
