Izinkinga eziningana okufanele uziqaphele ekwakhiweni kwezibani ze-LED zangaphandle
1.Abaklami bezibani zangaphandle kumele bacabangele indawo yokusebenza yezibani ze-LED zangaphandle
Ngenxa yendawo yokusebenza eyinkimbinkimbi, izibani ze-LED zangaphandle zithinteka yizimo zemvelo ezifana nezinga lokushisa, ukukhanya kwe-ultraviolet, umswakama, imvula, imvula, isihlabathi, igesi yamakhemikhali, njll. Ngokuhamba kwesikhathi, inkinga yokubola kokukhanya kwe-LED inkulu. Ngakho-ke, abaklami bokukhanyisa kwangaphandle kufanele bacabangele umthelela walezi zici zemvelo zangaphandle ekukhanyeni kwangaphandle kwe-LED lapho beklama.
2. Yini okufanele inakwe ekukhethweni kwezinto zokukhipha ukushisa kwezibani ze-LED zangaphandle
I-casing yangaphandle kanye nosinki wokushisa kuklanyelwe ukuhlanganiswa ukuxazulula inkinga yokukhiqiza ukushisa kwe-LED. Le ndlela ikhethwa, futhi i-aluminium noma i-aluminium alloy, ithusi noma i-alloy yethusi, namanye ama-alloys ane-conductivity enhle yokushisa asetshenziswa ngokuvamile. I-heat dissipation ine-air convection heat dissipation, umoya onamandla wokupholisa ukushisa nokukhishwa kokushisa kwepayipi lokushisa. (Ukukhipha ukushisa okupholisa ijethi nakho kuwuhlobo lokupholisa amapayipi okushisa, kodwa isakhiwo siyinkimbinkimbi kakhulu.)
3. Ubuchwepheshe bokupakisha be-chip ye-LED yangaphandle
Njengamanje, izibani ze-LED (ikakhulukazi izibani zomgwaqo) ezikhiqizwa e-China zihlanganiswa kakhulu ngokusebenzisa ama-LED angu-1W ngezintambo eziningi nokuhambisana. Le ndlela inokumelana nokushisa okuphezulu kunobuchwepheshe bokupakisha obuphambili, futhi akulula ukukhiqiza izibani zekhwalithi ephezulu. Noma ingahlanganiswa namamojula angu-30W, 50W noma amakhulu nakakhulu ukuze kuzuzwe amandla adingekayo. Izinto zokupakisha zalawa ma-LED zimbozwe ku-epoxy resin futhi zifakwe ku-silicone. Umehluko phakathi kwalokhu okubili ukuthi iphakheji ye-epoxy resin inokumelana okuphansi kwezinga lokushisa futhi ijwayele ukuguga ngokuhamba kwesikhathi. Iphakethe le-silicone lingcono ekumelaneni nezinga lokushisa futhi kufanele likhethwe lapho usebenzisa.
Kungcono ukusebenzisa i-multi-chip kanye nosinki wokushisa njengephakheji lonke, noma ukusebenzisa iphakheji ye-aluminium substrate multi-chip bese uxhuma izinto zokushintsha isigaba noma igrisi ekhipha ukushisa kusinki yokushisa, kanye nokumelana nokushisa. yomkhiqizo iphakeme kunaleyo yomkhiqizo ohlanganiswe nedivayisi ye-LED. Ukumelana nokushisa okukodwa kuya kokubili, okusiza kakhulu ekulahlekeni kokushisa. Ngemojula ye-LED, i-module substrate ngokuvamile iyi-substrate yethusi, futhi uxhumano ne-sink yokushisa yangaphandle iwukusebenzisa impahla yokuguqula isigaba esihle, noma igrisi enhle yokukhipha ukushisa ukuze kuqinisekiswe ukuthi ukushisa ku-substrate yethusi kungadluliselwa ukushisa kwangaphandle kuzika ngesikhathi. Ukukhuphuka, uma ukucubungula kungalungile, kuzobangela kalula ukuqoqwa kokushisa kubangele izinga lokushisa le-module chip likhuphuke kakhulu, okuzothinta ukusebenza okuvamile kwe-chip ye-LED. Umbhali ukholelwa ukuthi: iphakethe le-multi-chip lifanele ukwenziwa kwezinto zokukhanyisa ezijwayelekile, ukupakishwa kwemojula kulungele izikhathi ezilinganiselwe ukuze kukhiqizwe izibani eziholayo ezihlangene (njengamalambu okukhanyisa okuyinhloko kwezimoto, njll.).
4.Ucwaningo lokuklanywa kwerediyetha yesibani se-LED yangaphandle luyingxenye ebalulekile yesibani se-LED. Umumo wayo, ivolumu kanye nendawo echitha ukushisa kumele yakhelwe ukuthi ibe yinzuzo. I-radiator incane kakhulu, izinga lokushisa elisebenzayo lesibani se-LED liphezulu kakhulu, lithinta ukusebenza kahle okukhanyayo nokuphila isikhathi eside, uma i-radiator inkulu kakhulu, ukusetshenziswa kwezinto kuzokwandisa izindleko nesisindo somkhiqizo, futhi ukuncintisana komkhiqizo kuzokwandisa. nciphisa. Kubalulekile ukuklama i-radiator yokukhanya ye-LED efanelekile. Idizayini yesinki yokushisa inezingxenye ezilandelayo:
1.Ukuchaza amandla adingwa izibani ze-LED ukuze zikhiphe ukushisa.
I-2.Yakha amapharamitha athile okushisa okushisa: ukushisa okuqondile kwensimbi, ukuqhutshwa kokushisa kwensimbi, ukumelana nokushisa kwe-chip, ukumelana nokushisa kokushisa kokushisa, nokumelana nokushisa komoya ozungezile.
3.Thola uhlobo lokuhlakazeka, (ukupholisa kwe-convection yemvelo, ukupholisa umoya onamandla, ukupholisa amapayipi okushisa, nezinye izindlela zokulahla ukushisa.) Kusukela ekuqhathanisweni kwezindleko: ukupholisa kwe-convection yemvelo izindleko eziphansi kakhulu, indawo yokupholisa umoya onamandla, izindleko zokupholisa ipayipi lokushisa ziphezulu. , izindleko zokupholisa indiza ziphezulu kakhulu .
4.Thola izinga lokushisa eliphezulu lokusebenza elivunyelwe izibani ze-LED (izinga lokushisa elizungezile kanye nokukhuphuka kwezinga lokushisa lokuvunyelwa kwe-luminaire)
5.Bala ivolumu kanye nendawo yokukhipha ukushisa kwesitsha sokushisa. Futhi unqume ukuma kwe-sink yokushisa.
6. Hlanganisa irediyetha kanye nesibani se-LED sibe isibani esiphelele, futhi usebenze kuso amahora angaphezu kwayisishiyagalombili. Hlola izinga lokushisa le-luminaire ekamelweni lokushisa elingu-39 °C - 40 °C ukuze ubone ukuthi izimfuneko zokulahla ukushisa ziyahlangatshezwa yini ukuze uqinisekise ukuthi isibalo silungile yini. Izimo, bese ubala kabusha futhi ulungise amapharamitha.
7.Uphawu lwerediyetha kanye nomthunzi wesibani kufanele kungangeni manzi futhi kungangeni uthuli. Iphedi yenjoloba elwa nokuguga noma iphedi yerabha ye-silicone kufanele ihlanganiswe phakathi kwesembozo sesibani nosinki wokushisa. Kufanele iboshwe ngamabhawodi ensimbi engagqwali ukuqinisekisa ukuthi ingangeni emanzini futhi ingangenisi uthuli. Izinto, maqondana nemininingwane yobuchwepheshe yakamuva yokukhanyisa ngaphandle okumenyezelwe yi-China, kanye nezindinganiso zokuklanywa kokukhanyisa umgwaqo wasemadolobheni, lolu ulwazi olubalulekile lwabaklami bezibani zangaphandle.
