Kulezi zinsuku, kunezinhlobo eziningi LED , okukhazimulisa amakhasimende amaningi. Izibonakaliso ze-Commercial LED zokukhangisa zifakwe kuma-plaza amakhulu wokuhweba. Kodwa-ke, imikhiqizo yokubonisa ye-LED ayihambisani kahle, okuholela ezinkingeni zokuphepha ze-LED njalo, futhi umlilo uyinkinga enkulu. Kungani isibonakaliso se-LED sibamba umlilo?
Okokuqala, ikhebula lamandla: ikhwalithi yekhebula emakethe imile, izintambo eziningi zensimbi ziyi-aluminium egqoke i-aluminium, ubuso bufana nocingo lwethusi, umkhuba u-aluminium alloy wire; le ntambo / ikhebula ngokuvamile lisetshenziselwa ukusetshenziswa kwesikhashana, ngokuyisisekelo alinakusetshenziswa kumkhiqizo ojwayelekile. Kukhona ukungabaza ngethusi ngocingo lwethusi, ukungabaza ngongqimba lwe-insulation, nokungabaza ngobubanzi be-wire (izidingo ezivamile ziphindwe izikhathi ezingaphezu kwezingu-1.2 amandla amakhulu wesibonisi) .Munye kuphela wale mibuzo onganakwa, futhi bazongcwaba okufihliwe izingozi. Okwamanje kubangela izinhlekelele ezinkulu.
Okwesibili, ukunikezwa kwamandla: sebenzisa ukunikezwa kwamandla okuphansi, noma umkhawulo omkhulu wokusebenzisa amandla athe xaxa wokuphakelwa kwamandla, okuholele ekulayisheni okwedlula kwamandla kagesi (imvamisa kuphela u-70% wamandla athe xaxa wokuphakelwa kwamandla), bese ikhebula lamandla kagesi liphansi futhi ukuhogela akuqinile, lokhu kungaba imbangela yezingozi ezifihliwe zamaphoyisa;
Okwesithathu, ibhodi le-PCB: idatha yalo iphansi, ithusi lincane kakhulu, uhlelo alunangqondo, inqubo ayimpofu, ucingo lwethusi lunama-burrs nezinye izigcawu zizoba nesifunda esifushane, esiba ngumthombo wengozi yomlilo;
Okwesine, uhlelo lokupholisa. I LED display screen lizobheka ngamazinga ashisa kakhulu, futhi inkinga ukushabalalisa ukushisa kuba umbuzo wokuqala ukucutshungulwa funa. Uma uhlelo lokupholisa umoya lungenangqondo, luzoholela kalula ekubutheni uthuli kushaft enkulu yefeni, ukunikezwa kwamandla nebhodi elikhulu, okuholele ekusakazekeni kokushisa okuncane, isekhethi elifushane lezinto zikagesi, nokufa kukagesi fan, okwenza i-alamu.
Okwesihlanu, isevisi kanye nokugcinwa. Ngakolunye uhlangothi, umphakeli wokubonisa ubengenakho ukuqeqeshwa okuhlelekile ekuthengeni ikhasimende, okuholele ekusebenzeni okungajwayelekile. Esinye isici ukuthi umphakeli wesibonisi akenzanga ukugcinwa kwesibonisi se-LED esithengisiwe, futhi ukugcinwa kungenzeka kungabi yisikhathi sangempela esigabeni sokuqala, okwenza kube nzima ukusungula lesi simo ngesikhathi sangempela.
Ukuthi ukusebenza komlilo kwesibonisi se-LED kuyafaneleka yini ikakhulukazi kuhlobene nezici ezimbili zomlilo ezibonakalayo kanye nenqubo yebhokisi yesibonisi se-LED. Lapha, kugxilwe ekuhlaziyweni kwezinto ezine ezenza ukuthi isibonisi esiholile sabamba umlilo:
Isici seplastiki
Ikhithi yepulasitiki iyingxenye ebalulekile yezinto ezingavuthwa umlilo zokubonisa. Ngoba isetshenziselwa ikakhulukazi ikhava engezansi yesigaxa sephaneli yemayunithi, isebenzisa i-PC + ingilazi yefayibha yensimbi enomsebenzi ovutha amalangabi. Ayigcini nje ngokuba nomsebenzi we-flame retardant, kepha futhi ingakhubazeka, iphuke futhi iqhekeke ngaphansi kokushisa okuphezulu nokuphansi nokusetshenziswa kwesikhathi eside. Ngasikhathi sinye, isebenzisa ingcina enhle yokuvala uphawu, engavimba ngempumelelo amanzi emvula avela endaweni yangaphandle ukuthi angene ngaphakathi, ngaleyo ndlela igweme umlilo obangelwe yisifunda esifushane.
Isici se-Wire
Ukukhulisa isibonisi endaweni ngayinye yesibonisi, kukhula inani lamandla asetshenzisiwe, futhi kuphakama izidingo zokuqina kocingo. Phakathi kwemikhiqizo eminingi yocingo, kuphela ucingo oluhlangabezana nezinga likazwelonke olungasetshenziswa ukuqinisekisa ukuphepha nokuzinza kwalo. Lezi zidingo kufanele kuhlangatshezwane nazo lapho kukhethwa: Okokuqala, umnyombo kufanele ube yithwali elihambisa izintambo zethusi. Okwesibili, ukubekezelelana okuyisisekelo sendawo yocingo kungaphakathi kwenani elijwayelekile lobubanzi. Ekugcineni, ukwahlukanisa kanye nelangabi retardancy wenjoloba eyisisekelo ehlanganisiwe kufanele ihlangabezane nokujwayelekile.
Isici samandla
Lapho ukhetha ukunikezwa kwamandla, ukunikezwa kwamandla okuqinisekiswe yi-UL kuphela okungcono kakhulu. Ngoba isilinganiso sayo sokuguqula esisebenzayo siqinisekisa ukuphepha nokuqina komthwalo wokuphakelwa kwamandla, ungasebenza ngokujwayelekile noma ngabe izinga lokushisa langaphandle lishisa.
Isici sezinto zokuvikela sangaphandle
Kubaluleke kakhulu ekukhetheni ukwakheka kwangaphandle kwesibonisi. Ngoba iphaneli ye-aluminium-plastic wokubonisa ongaphandle unenani eliphansi elingacimi umlilo, ikhula ngokushesha ngethempelesha ephezulu nemvula namakhaza, ukuze ikwazi ukungena kalula emzimbeni wesikrini ngenkathi yesimo sezulu esinomswakama, okuholela kalula elekthronikhi. Isifunda esifushane kuleso sakhi sidala umlilo. Ngakho-ke, kufanele sikhethe iphaneli ye-aluminium-plastic enebanga eliphakeme lokucisha umlilo emakethe, ukuze ukumelana nomlilo kuhle kakhulu, impahla ecisha umlilo inamandla, nokusebenza kokuguga komoya-mpilo kokuqukethwe okuyisisekelo kuqinile, ukuze ukugwema umlilo.
