Ngaphambi kokuba kuvele izibani ezingaqhumi, izinkampani eziningi zazifake izibani ezijwayelekile.Ngenxa yokuthi amalambu avamile ayengenazo izinto ezinhle zokuvikela ukuqhuma, kwabangela izingozi ezithile zasefekthri ukuba zenzeke njalo futhi zabangela ukulahlekelwa okukhulu ebhizinisini.Imboni ijwayele ukukhiqiza izinto ezivuthayo neziqhuma ngesikhathi sokukhiqiza.Ngenxa yokuthi izinto zokukhanyisa zikhiqiza izinhlansi zikagesi ngokungenakugwenywa noma zakha izindawo ezishisayo lapho zisebenza, zihlangana namagesi avuthayo futhi zithungele la magesi, azodala izingozi.Isibani esingaqhumi sinomsebenzi wokuhlukanisa igesi evuthayo nothuli.Kulezi zindawo eziyingozi, ingavimbela izinhlansi nezinga lokushisa eliphezulu ekuthungeleni igesi evuthayo nothuli endaweni ezungezile, ukuze kuhlangatshezwane nezidingo zokuvikela ukuqhuma.
Izimo ezihlukene zengxube yegesi evuthayo zinezidingo ezihlukene zebanga lokuvikela ukuqhuma kanye nefomu lokuvikela ukuqhuma kwe-ex lamp.Ngokwezidingo zezindawo ezihlukene zengxube yegesi evuthayo, izibani zethu ezivame ukusetshenziswa ezivikela ukuqhuma zinamamaki okuvikela i-IIB ne-IIC.Kunezinhlobo ezimbili zezinhlobo zokuvikela ukuqhuma: okungangenwa ukuqhuma ngokuphelele (d) kanye nenhlanganisela yokuvikela ukuqhuma (de).Imithombo yokukhanya yezibani ezingaqhumi ingahlukaniswa izigaba ezimbili.Olunye uhlobo lwemithombo yokukhanya amalambu e-fluorescent, amalambu ensimbi e-halide, amalambu e-sodium anengcindezi ephezulu, namalambu angenawo ama-electrode avame ukusetshenziswa ezibanini ezikhipha igesi.Omunye umthombo wokukhanya we-LED, ongahlukaniswa ngomthombo wokukhanya kwesichibi kanye nomthombo wokukhanya ohlanganisiwe we-COB.Izibani zethu zangaphambilini ezingaqhumi bezisebenzisa imithombo yokukhanya yokukhipha igesi.Njengoba izwe lihlongoza imithombo yokukhanya ye-LED yokonga nokunciphisa ukukhishwa kwe-emission, iye yakhuphuka kancane kancane futhi yanda.
Yiziphi izici zesakhiwo zamalambu angaqhumi?
lNgokusebenza okuhle kokuvikela ukuqhuma, ingasetshenziswa kalula kunoma iyiphi indawo eyingozi.
lUkusebenzisa i-LED njengomthombo wokukhanya kunokusebenza okuphezulu, ububanzi bokukhanya kwemisebe, futhi impilo yesevisi ingafinyelela iminyaka eyishumi.
lInokuhambisana okuhle kwe-electromagnetic ukuqinisekisa ukuthi ngeke kuthinte indawo yokusebenza ezungezile.
lUmzimba wesibani wenziwe ngezinto ezilula ze-alloy, ezinezinzuzo zokumelana nokugqwala okuqinile kanye nokumelana nomthelela;ingxenye esobala yenziwe ngengilazi eqinile eqinile futhi imelana nokushisa okuphezulu.
lIsayizi encane, kulula ukuyiphatha, ilungele ukusetshenziswa ezindaweni ezahlukahlukene, futhi kulula ukuyiqonda.
Athini amazinga okuvikela ezindawo ezivalekile zamalambu angaqhumi?
Ukuze uvimbele uthuli, izinto zangaphandle eziqinile kanye namanzi ukuthi angangeni emgodini wesibani, ukuthinta noma ukunqwabelana ezingxenyeni ezibukhoma ukuze kubangele ukukhanya, umjikelezo omfishane noma ukulimala kokufakwa kukagesi, kunezindlela ezihlukahlukene zokuvikela i-enclosure ukuvikela ukufakwa kukagesi.Sebenzisa uhlamvu lwesici "IP" olulandelwa izinombolo ezimbili ukuze ubonise ileveli yokuvikela indawo ebiyelwe.Inombolo yokuqala ikhombisa ikhono lokuvikela kubantu, ezintweni zangaphandle eziqinile noma uthuli.Ihlukaniswe yaba amazinga 0-6.I-luminaire evikela ukuqhuma iwuhlobo lwesibani esivaliwe, ikhono layo lokuvikela uthuli okungenani li-4 noma ngaphezulu.Inombolo yesibili ikhombisa ikhono lokuvikela amanzi, elihlukaniswe ngamamaki angu-0-8.
Ungakhetha kanjani amalambu angaqhumi?
1. Umthombo wokukhanya we-LED
Kuyadingeka ukusebenzisa ama-chips e-LED anokukhanya okuphezulu, ukusebenza kahle okuphezulu kokukhanya kanye nokuncishiswa kokukhanya okuphansi.Lokhu kudinga ukukhethwa kobuhlalu besibani se-LED obupakishwe ngamashiphu eshaneli avamile avela kubathengisi bama-chip omkhiqizo njenge-American Kerui/German Osram, njll., intambo yegolide epakishiwe/impushana ye-phosphor/insulating glue, njll. Bonke badinga ukusebenzisa izinto ezihlangabezana nezimfuneko.Ngesikhathi sokuthenga,** khetha umkhiqizi osebenza ngokukhethekile ekukhiqizeni izibani zezimboni.Imikhiqizo imboza izibani eziqeqeshiwe kanye nezibani ezihlukahlukene ezivikela ukuqhuma ezisetshenziswa ezindaweni ezingaqhumeki.
2. Amandla okushayela
I-LED iyingxenye ye-semiconductor eguqula ama-electron e-DC abe amandla okukhanya.Ngakho-ke, idrayivu ezinzile idinga i-chip yomshayeli wamandla aphezulu.Ngesikhathi esifanayo, umsebenzi wokunxeshezelwa kwesici samandla pu uyadingeka ukuze kuqinisekiswe ukusebenza kahle kwamandla.Amandla ayisici esibalulekile kuso sonke isibani.Njengamanje, ikhwalithi yamandla kagesi we-LED emakethe ayilingani.Ukunikezwa kwamandla okushayela okuhle akuqinisekisi kuphela ukunikezwa kwe-DC okuzinzile, kodwa futhi kuqinisekisa ngokugcwele ukuthuthukiswa kokusebenza kahle kokuguqulwa.Le parameter ibonisa ukonga kwangempela kwamandla futhi Akukho mfucuza kugridi.
3. Uhlelo lokukhipha ukushisa olunokubukeka okuhlangene kanye nesakhiwo sezibani ze-LED ezingaqhumisi
I-luminaire evikela ukuqhuma inokubukeka okulula nokuhle, umthombo wokukhanya wekhwalithi ephezulu kanye nokunikezwa kwamandla, futhi okubaluleke kakhulu, ukuhlakanipha kwesakhiwo segobolondo.Lokhu kuhilela ukuchithwa kokushisa kwesibani se-LED.Njengoba i-LED iguqula amandla okukhanya, ingxenye yamandla kagesi nayo iguqulwa ibe amandla e-Thermal idinga ukuhlakazwa emoyeni, ukuze kuqinisekiswe ukukhanya okuzinzile kwe-LED.Ukushisa okuphezulu kwesibani se-LED kuzodala ukubola kokukhanya kusheshise futhi kuthinte impilo yesibani se-LED.Kuhle ukusho ukuthi ubuchwepheshe bama-chips e-LED buyaqhubeka buthuthuka, ukusebenza kahle kokuguqulwa nakho kuthuthukisiwe, inani lokusetshenziswa kukagesi ukuguqula ukushisa lizoba lincane, i-sink yokushisa izoba mncane, futhi izindleko zizoncishiswa ngenxa yokunye, okuyinto ehambisana nokuphromotha ama-LED.Lesi yisiqondiso sokuthuthukiswa kwezobuchwepheshe.Njengamanje, ukuchithwa kokushisa kwegobolondo kuseyipharamitha okufanele kugxilwe kuyo.
