Ingangeni manziUkuhlaziywa kobuchwepheshe kwezibani ze-LED zangaphandle
Izinto zokukhanyisa zangaphandle zidinga ukumelana nokuhlolwa kweqhwa neqhwa, umoya nombani, futhi izindleko ziphezulu. Ngenxa yokuthi kunzima ukulungiswa odongeni olungaphandle, kufanele luhlangabezane nezidingo zomsebenzi ozinzile wesikhathi eside. I-LED iyisici esibucayi se-semiconductor. Uma imanzi, i-chip izomunca umswakama futhi ilimaze i-LED, i-PcB nezinye izakhi. Ngakho-ke, i-LED ifanele ukomisa nokushisa okuphansi. Ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwama-LED ngaphansi kwezimo ezinzima zangaphandle, ukwakheka kwesakhiwo esingenamanzi samalambu kubaluleke kakhulu.
Njengamanje, ubuchwepheshe obungangeni manzi bezibani buhlukaniswe ngokuyinhloko ngezindlela ezimbili: ukuvimbela amanzi kwesakhiwo kanye nokuvimbela amanzi. Okubizwa ngokuthi ukuvimbela amanzi kwesakhiwo ukuthi ngemva kokuhlanganiswa kwezingxenye ezihlukahlukene zesakhiwo somkhiqizo, bekulokhu kungangeni manzi. Impahla ayinamanzi, ukuze kuthi lapho umkhiqizo uklanywe, isikhundla se-potting glue ukuze sivale izingxenye zikagesi sishiywe, futhi impahla yeglue isetshenziselwa ukuvimbela amanzi ngesikhathi somhlangano. Imiklamo emibili engangeni manzi iyatholakala emizileni ehlukene yomkhiqizo, ngayinye inezinzuzo zayo.
Izinto ezithinta ukusebenza kwezibani ezingangeni manzi
1, ukukhanya kwe-ultraviolet
Imisebe ye-Ultraviolet inomthelela olimazayo ekufakweni kwentambo, okokuvikela kwangaphandle, izingxenye zepulasitiki, iglue yasebhodweni, umucu werabha oyindandatho yokuvala kanye nokunamathiswa okuvezwe ngaphandle kwesibani.
Ngemuva kokuthi ungqimba lwe-insulation lwezintambo lukhulile futhi luqhekekile, umhwamuko wamanzi uzongena ngaphakathi kwesibani ngegebe lenkambo yocingo. Ngemuva kokuthi ukumbozwa kwendlu yesibani sekugugile, ukugqoka emaphethelweni e-casing kuqhekekile noma kuhlutshiwe, futhi igebe lingenzeka. Ngemuva kweminyaka yecala lepulasitiki, lizokhubazeka futhi liqhekeke. Ukuguga kwejeli ye-electronic potting kubangela ukuqhekeka. Umucu werabha ovala uphawu uyaguga futhi ukhubazekile, futhi kuzovela igebe. I-adhesive phakathi kwamalungu esakhiwo isikhulile, futhi igebe liyakhiwa ngemva kokuba ukunamathela kwehlisiwe. Konke lokhu kuwumonakalo ekhonweni elingangeni manzi le-luminaire ngokukhanya kwe-ultraviolet.
2, izinga lokushisa eliphezulu neliphansi
Izinga lokushisa langaphandle liyahlukahluka kakhulu nsuku zonke. Ehlobo, izinga lokushisa elingaphezulu kwezibani lingakhuphukela ku-50-60° C, futhi izinga lokushisa lehla liye ku-10-20 qC kusihlwa. Izinga lokushisa ebusika neqhwa lingehla libe ngaphansi kukaziro, futhi umehluko wezinga lokushisa ushintsha kakhulu unyaka wonke. Ukukhanyisa kwangaphandle endaweni yokushisa ephezulu ehlobo, impahla isheshisa ukuguga ukuguga. Lapho izinga lokushisa lehla ngaphansi kweziro, izingxenye zepulasitiki ziba brittle, ngaphansi kwengcindezi yeqhwa neqhwa noma ukuqhekeka.
3, ukunwetshwa ezishisayo kanye ukusifinyeza
Ukunwetshwa kwe-thermal kanye nokuncipha kwendlu yesibani: Ukushintsha kwezinga lokushisa kubangela ukwanda nokuncipha kwesibani. Izinto ezihlukile (ezifana namaphrofayela engilazi ne-aluminium) zinama-coefficients ahlukile womugqa wokunweba, futhi izinto ezimbili zizosuswa endaweni ehlanganyelwe. Inqubo yokwandisa nokunciphisa okushisayo iphindaphindiwe ngokuqhubekayo, futhi ukufuduka kwesihlobo kuphindaphindiwe ngokuqhubekayo, okulimaza kakhulu ukungabikho komoya kwesibani.
Ukwanda nokuncipha kokushisa komoya wangaphakathi: Ukufiphala kwamaconsi amanzi engilazini yesibani egqitshiwe ngokuvamile kungabonwa esitezi esiyisikwele, futhi amaconsi amanzi angena kanjani esibanini esigcwele ingcina ye-potting? Lokhu kuwumphumela wokuphefumula ngesikhathi sokwanda nokuncipha kokushisa.
4, ukwakheka kokungangeni kwamanzi
Izibani ezisuselwe ekwakhiweni kwesakhiwo esingangeni manzi kudingeka zihlanganiswe ngokuqinile nendandatho evalekayo ye-silicone. Isakhiwo se-casing yangaphandle sinembe kakhulu futhi siyinkimbinkimbi. Ivamise ukufaneleka izibani ezinosayizi omkhulu, njengezibani ze-strip floodlights, izibani eziyisikwele neziyisiyingi, njll. Ukukhanyisa.
5, impahla engangeni manzi
Umklamo ongenamanzi wezinto ezibonakalayo ufakwe ngaphakathi futhi uvinjelwe amanzi ngokugcwalisa i-potting glue, futhi ukuhlanganiswa phakathi kwezingxenye zesakhiwo esivaliwe kuhlanganiswe ne-glue yokufaka uphawu, ukuze izingxenye zikagesi zingabi namoya ngokuphelele futhi umphumela wokungena kwamanzi wokukhanya kwangaphandle ufinyelelwe.
6, i-glue yokupheka
Ngokuthuthuka kobuchwepheshe bezinto ezingangeni manzi, izinhlobo nezinhlobo ezahlukahlukene zeglue zokubumba ezikhethekile ziye zavela ngokuqhubekayo, ngokwesibonelo, i-epoxy resin eguquliwe, i-polyurethane resin eguquliwe, ijeli ye-silica eguquliwe, nokunye okunjalo. Amafomula amakhemikhali ahlukene, izakhiwo ezingokomzimba nezamakhemikhali zenjoloba yokubumba, njengokunwebeka, ukuzinza kwesakhiwo samangqamuzana, ukunamathela, i-anti-uV, ukumelana nokushisa, ukumelana nokushisa okuphansi, ukuxosha amanzi kanye nezakhiwo zokufakwa kwe-insulation, zihlukile.
Isiphetho
Kungakhathalekile ukuvinjwa kwamanzi kwesakhiwo noma ukuvikela amanzi okubalulekile, ekusebenzeni okuzinzile kwesikhathi eside kanye nezinga eliphansi lokuhluleka kokukhanyisa kwangaphandle, umklamo owodwa ongangeni manzi kunzima ukufeza ukwethembeka okuphezulu kakhulu, futhi ingozi engaba khona efihliwe yokugeleza kwamanzi isekhona.
Ngakho-ke, ukuklanywa kwezibani ze-LED zangaphandle eziphezulu kunconywa ukuthi kusetshenziswe ubuchwepheshe obungangeni manzi ukuze kuhlanganiswe izinzuzo zesakhiwo sokuvimbela amanzi kanye nobuchwepheshe bokuvimbela amanzi ukuze kuthuthukiswe ukuzinza kwesikhathi eside kwesifunda se-LED. Uma impahla ingenawo amanzi, ingafakwa kumshini wokuphefumula ukuze kuqedwe ukucindezela okubi. Idizayini yesakhiwo engangeni manzi ingabuye ibhekwe njengokwandisa ibhodwe, ukuvikeleka okuphindwe kabili kokuvikela amanzi, ukuthuthukisa ukuzinza kokukhanya kwangaphandle ukuze kusetshenziswe isikhathi eside, kanye nokunciphisa izinga lokuhluleka komswakama.
