Ukuhlaziywa kwesicelo sokukhanyisa kwe-LED esifundeni esibandayo
Ngemuva kweminyaka engu-10 yokuthuthukiswa okusheshayo, ukukhanya kwe-LED kungene esigabeni sokukhushulwa ngokushesha, futhi isicelo semakethe siye sanda kancane kancane kusukela esifundeni sokuqala esiseningizimu kuya ezindaweni ezimaphakathi nesentshonalanga. Kodwa-ke, ekusebenzeni kwangempela, sithole ukuthi imikhiqizo yokukhanyisa yangaphandle esetshenziswa eningizimu ihlolwe kahle ezindaweni ezisenyakatho, ikakhulukazi enyakatho-mpumalanga. Lesi sihloko sihlaziya ezinye zezinto ezibalulekile ezithinta ukukhanya kwe-LED ezindaweni ezibandayo, ithola izixazululo ezihambisanayo, futhi ekugcineni ikhiphe izinzuzo zemithombo yokukhanya ye-LED.
Okokuqala, izinzuzo zokukhanyisa kwe-LED ezindaweni ezibandayo
Uma kuqhathaniswa nesibani sokuqala se-incandescent, isibani se-fluorescent nesibani sokukhipha igesi esiphezulu, ukusebenza kwedivayisi ye-LED kungcono kakhulu ekushiseni okuphansi, futhi kungashiwo ukuthi ukusebenza kwe-optical kuhle kakhulu kunokushisa okujwayelekile. Lokhu kuhlobene eduze nezici zokushisa zedivayisi ye-LED. Njengoba izinga lokushisa le-junction liyancipha, ukukhanya okukhanyayo kwesibani kuzokwanda ngokuqhathaniswa. Ngokomthetho wokukhipha ukushisa kwesibani, izinga lokushisa le-junction lihlobene eduze nezinga lokushisa elizungezile. Uma izinga lokushisa eliphansi liphansi, izinga lokushisa lendawo lizokwehla. Ngaphezu kwalokho, ukwehlisa izinga lokushisa le-junction nakho kunganciphisa inqubo yokubola kokukhanya komthombo wokukhanya we-LED futhi kubambezele impilo yesevisi yesibani, okubuye kube isici sezingxenye eziningi ze-elekthronikhi.
Ubunzima kanye Nezinyathelo Zokuphikisa Zokukhanyisa kwe-LED endaweni ebandayo
Nakuba i-LED ngokwayo inezinzuzo eziningi ezimweni ezibandayo, ayikwazi ukunakwa lokho ngaphezu kwemithombo yokukhanya. Amalambu e-LED nawo ahlobene eduze namandla okushayela, izinto zomzimba wesibani, nesimo sezulu esinenkungu, i-ultraviolet enamandla nezinye izimo zezulu ezibanzi ezindaweni ezibandayo. Izinto zilethe izinselele ezintsha kanye nezinkinga ekusetshenzisweni kwalo mthombo wokukhanya omusha. Kuphela ngokucacisa lezi zingqinamba nokuthola izixazululo ezihambisanayo, singakwazi ukudlala ngokugcwele izinzuzo zemithombo yokukhanya ye-LED futhi sikhanye endaweni ebandayo.
1. Inkinga yokuqaliswa kwezinga lokushisa eliphansi lokunikezwa kwamandla okushayela
Wonke umuntu owenza ukuthuthukiswa kokunikezwa kwamandla uyazi ukuthi izinga lokushisa eliphansi ukuqala kokunikezwa kwamandla kuyinkinga. Isizathu esiyinhloko ukuthi iningi lezixazululo zamandla avuthiwe ezikhona azihlukaniseki ekusetshenzisweni okubanzi kwama-electrolytic capacitor. Kodwa-ke, endaweni yokushisa ephansi engaphansi -25 ° C, umsebenzi we-electrolytic we-electrolytic capacitor uyancipha kakhulu, futhi umthamo we-capacitance uncishisiwe kakhulu, okubangela ukuthi isifunda singasebenzi kahle. Ukuze uxazulule le nkinga, okwamanje kunezixazululo ezimbili: eyodwa iwukusebenzisa ama-capacitor aphezulu ngebanga lokushisa elibanzi lokusebenza, okuzokwandisa izindleko. Okwesibili umklamo wesifunda usebenzisa ama-electrolytic capacitor, afaka ama-ceramic laminated capacitor, kanye nezinye izikimu zokushayela ezifana ne-linear drive.
Ngaphezu kwalokho, ngaphansi kwemvelo yokushisa ephansi, ukusebenza kwe-voltage ye-voltage yemishini ejwayelekile ye-elekthronikhi nakho kuzokwehla, okuzophazamisa ukuthembeka okuphelele kwesekethe, okudinga ukunakwa okukhethekile.
2. Ukuthembeka kwezinto zepulasitiki ngaphansi komthelela wokushisa ophakeme futhi ophansi
Ngokocwaningo olwenziwa abacwaningi kwezinye izikhungo zocwaningo ekhaya nakwamanye amazwe, izinto eziningi zepulasitiki nezenjoloba ezivamile zinokuqina okubuthakathaka kanye nokuqina okukhulayo emazingeni okushisa aphansi angaphansi -15 ° C. Ngemikhiqizo yangaphandle ye-LED, izinto ezibonakalayo, amalensi optical, izimpawu nokunye. izingxenye zesakhiwo zingase zisebenzise izinto zepulasitiki, ngakho-ke izici zemishini ezisezingeni eliphansi zalezi zinto zidinga ukucatshangelwa ngokucophelela, ikakhulukazi izingxenye ezithwala umthwalo, ukugwema izibani ngaphansi kwemvelo ephansi yokushisa, izoqhuma ngemva kokushaywa umoya onamandla futhi ukushayisana ngengozi.
Ngaphezu kwalokho, izibani ze-LED zivame ukusebenzisa inhlanganisela yezingxenye zepulasitiki nensimbi. Ngenxa yokuthi ama-coefficients okunweba wezinto zepulasitiki nezinto zensimbi ahluke kakhulu ngaphansi kokuhluka okukhulu kokushisa, isibonelo, ama-coefficients okwandisa we-aluminium yensimbi nezinto zepulasitiki ezivame ukusetshenziswa ezibani zihluke izikhathi ezi-5, ezingabangela ukuba izinto zepulasitiki ziqhekeke noma igebe. phakathi kwakho kokubili. Uma inyuswa, isakhiwo se-waterproof seal sizogcina singavumelekile, okuzodala izinkinga zomkhiqizo.
Ezifundeni ezisezintabeni, kusukela ngo-October kuya ku-April wonyaka olandelayo, kungase kube ngenkathi yeqhwa neqhwa. Izinga lokushisa lesibani se-LED lingase libe ngaphansi kuka -20 ℃ kusihlwa ngaphambi kokuba isibani sikhanyiswe kusihlwa, bese kuthi ngemva kokuvulwa kukagesi ebusuku, izinga lokushisa lomzimba wesibani lingakhuphukela ku-30 ℃ ～ 40. ℃ ngenxa yokushisa kwesibani. Izwa ukushaqeka komjikelezo wezinga lokushisa eliphezulu neliphansi. Kule ndawo, uma ukwakheka kwesakhiwo se-luminaire kanye nenkinga yokufanisa izinto ezahlukene kungaphathwa kahle, kulula ukubangela izinkinga zokuqhekeka kwezinto kanye nokuhluleka kokungena kwamanzi okukhulunywe ngenhla.
