Izindaba zomphakathi nezemvelo
Lapho kukhiqizwa ama-chips e-LED, ama-acids e-inorganic, ama-oxidants, ama-complexing agents, i-hydrogen peroxide, izinyibilikisi eziphilayo nezinye izinto zokuhlanza ezisetshenziswa enqubweni yokukhiqiza i-substrate, kanye nesigaba segesi ye-organic organic kanye negesi ye-ammonia esetshenziselwa ukukhula kwe-epitaxial, inobuthi. nokungcolisa. Lezi futhi izinto zamakhemikhali ezivamile ezivame ukusetshenziswa ekukhiqizeni amasekethe ahlanganisiwe we-semiconductor nezinye izimboni. Ezinkampanini ze-chip ze-LED ezingaphansi kwalesi sigaba sobuchwepheshe obuphezulu, ubuchwepheshe bazo bokucubungula kanye nezinqubo ziqinile futhi ziyasebenza, okwenza kube lula ukwenza ukwelashwa okungenangozi.
Imishini yokulawula i-LED (ngokuvamile eyaziwa ngokuthi izinsiza zamandla okushayela) awehlukile kumalambu endabuko e-fluorescent, amalambu ensimbi e-halide, namanye ama-ballasts kagesi, kanye nobuthi nokungcola okukhiqizwa ekukhiqizeni izinto ezihlukahlukene ezivamile zabathengi.
Igobolondo le-aluminium alloy elivame ukusetshenziswa ezibani ze-LED lifana nokukhiqizwa kwegobolondo le-aluminium yendabuko, futhi ubuthi nokungcola okukhiqizwa phakathi nenqubo yokukhiqiza amagobolondo epulasitiki noma ensimbi okungenani akunyuki kakhulu.
Ngamafuphi, asikho isidingo sokukhathazeka ngemikhiqizo yokukhanyisa i-semiconductor abantu abahlangana nayo ngokuqondile, kanye nezindaba zemvelo ngesikhathi sokukhiqiza.

Ukukhathazeka ngokuphepha kwabantu
1. I-voltage ye-LED ephansi iphephe kakhulu futhi idukisa umphakathi
Abasebenzi abaningi bezobuchwepheshe emabhizinisini banokuqonda okungajulile nokungaphelele kokuphepha kukagesi kwemikhiqizo yokukhanyisa i-LED kanye nempahla yamandla okushayela, okuholela ekuphepheni kukagesi kwemikhiqizo eminingi yokukhanyisa ye-LED eklanywe futhi ekhiqizwayo ethembele ngokuphelele ekuphepheni kwamandla okushayela. Kodwa-ke, ukuhlukaniswa kukagesi kanye nokufakwa kwezinto eziningi ezisekela amandla okushayela kwe-LED akuhlangabezani nezidingo ezijwayelekile. Ngaphezu kwalokho, inani elikhulu lokukhushulwa mayelana nokuphepha kwamandla kagesi aphansi we-LED lingadukisa abantu ukuthi bavame ukuthinta imikhiqizo, okuholela engcupheni ephezulu yokushaqeka kukagesi kunemikhiqizo yokukhanyisa yendabuko abantu abazi ngokungazi ukuthi amandla abo aphezulu ayingozi futhi abalokothi bathinte nje ngokunganaki. .
2. Inkinga yengozi yokukhanya okuluhlaza kwe-LED
I-LED emhlophe yohlobo lwe-chip eluhlaza okwesibhakabhaka ine-spectrum egxile kakhulu ku-spectrum eyingozi kunamalambu e-fluorescent, okuhlanganisa namalambu okonga amandla, okuholela ku-spectrum eyingozi cishe ngokuphindwe kabili kunezibani ze-fluorescent. Ukwengeza, indawo ekhishwayo incane futhi ukukhanya kuphezulu, okwenza ukulimala kokukhanya okuluhlaza kugqame kakhulu kunamanye amalambu. Kodwa-ke, ngokombono kanye nokuhlolwa kwesitifiketi sokuphepha komkhiqizo wesikhathi eside, empeleni, ngaphansi kuka-5% wezibani zedeskithophu ze-LED eziqine kakhulu zidlula izidingo zobungozi ze-RG1. Lezi zibani zidinga kuphela ukulebula ngophawu oluthi “Ungabheki ngokuqondile umthombo wokukhanya isikhathi eside” endaweni evelele futhi lubonise umkhawulo webanga eliphephile ukuze ukhumbuze abasebenzisi ukuthi bahlangabezane nezimfuneko ezijwayelekile. Angathengiswa futhi asetshenziswe ngaphandle kwezinkinga, okuphephe kakhulu kunokubheka ukukhanya kwelanga ngokuqondile isikhathi esifushane. Futhi ngokwengezwa kwesembozo se-sanding, izibani ze-LED azinazinkinga. Futhi akuwona ama-LED kuphela adala inkinga ye-biosafety. Eqinisweni, imithombo ethile yokukhanya yendabuko, njengezibani zakuqala ze-metal halide, ingase ibe nezingozi ezinkulu ze-UV ngisho nokukhanya okuluhlaza okwesibhakabhaka.
3. Inkinga ye-Strobe
Kufanele kushiwo ukuthi imikhiqizo yokukhanyisa kwe-LED ingaba engacwayizi kancane futhi izinze kakhulu ekukhipheni ukukhanya (njengamashayeli amaningi ahlanzekile e-DC atholakalayo emakethe). Futhi imikhiqizo eyenziwe kabi ingase futhi ibe nokucwayiza okukhulu (njengaleyo engenawo amandla okushayela, lapho igridi yamandla e-AC inikezela ngokuqondile amandla kuntambo ye-LED noma i-COB-LED), kodwa lokhu akuhlukile kakhulu nenkinga yokucwayiza kweshubhu eliqondile. izibani ze-fluorescent ezine-inductive ballast. Lokhu akuncikile emthonjeni wokukhanya we-LED, kodwa ekunikezeni amandla kanye nomthombo wamandla oshayelayo ohambisana nawo. Umgomo ofanayo uyasebenza ekucwayizeni kwemikhiqizo yokukhanyisa yomthombo wokukhanya wendabuko.
