Ulwazi oluyisisekelo lokukhanyisa kwangaphandle kwe-LED kungangeni manzi
Izinto zokukhanyisa zangaphandle zidinga ukumelana nokuhlolwa kweqhwa neqhwa, umoya nombani, futhi izindleko ziphezulu. Ngenxa yokuthi kunzima ukulungiswa odongeni olungaphandle, kufanele kuhlangabezane 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 engangeni manzi yindawo yengxenye kagesi evaliwe lapho umkhiqizo uklanywa. Izinto zeglue zisetshenziselwa ukuvimbela amanzi ngesikhathi somhlangano.
Izinto ezithinta ukusebenza kwezibani ezingangeni manzi
1, i-ultraviolet
Imisebe ye-Ultraviolet inomthelela olimazayo ekufakweni kwentambo, okokuvikela kwangaphandle, izingxenye zepulasitiki, iglue yasebhodweni, umucu werabha oyindandatho yokuvala kanye nenamathelayo evezwe 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. I-electron potting colloids ingaqhekeka lapho isikhulile. Umucu werabha ovala uphawu uyaguga futhi ukhubazekile, futhi kuzovela igebe. I-adhesive phakathi kwamalungu esakhiwo isikhulile, futhi igebe liyakhiwa ngemva kokuba amandla okunamathela ehlisiwe. Konke lokhu kuwumonakalo ekhonweni lokungangeni kwamanzi le-luminaire.
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 ℃ 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 kwe-Thermal kanye nokufinyela
Ukunwetshwa kwe-thermal kanye nokuncipha kwendlu yesibani: Ukushintsha kwezinga lokushisa kubangela ukwanda okushisayo nokufinyela kwesibani. I-coefficient yokunwetshwa komugqa yezinto ezihlukene ihlukile, futhi izinto ezimbili zizosuswa endaweni ehlangene. Inqubo yokwandisa nokunciphisa okushisayo iphindaphindiwe ngokuqhubekayo, futhi ukufuduka kwesihlobo kuphindaphindiwe ngokuqhubekayo, okulimaza kakhulu ukuqina komoya kwesibani.
4, Isakhiwo Sokungenwa Manzi
Izibani ezisuselwe ekwakhiweni kwesakhiwo esingangeni manzi kumele zihlanganiswe ngokuqinile nendandatho yokuvala i-silicone. Isakhiwo se-casing yangaphandle sinembe kakhulu futhi siyinkimbinkimbi. Ivamise ukufaneleka izibani ezinosayizi omkhulu, njengezibani ze-strip floodlights, izibani eziyisikwele neziyisiyingi, njll. Ukukhanyisa.
Kodwa-ke, ukwakheka komklamo we-luminaire ongangeni manzi kunezidingo eziphakeme zomshini, futhi ubukhulu bengxenye ngayinye kufanele bufaniswe ngokunembile. Izinto ezingenamanzi kuphela ezingaqinisekiswa ngezinto ezifanele kanye nokwakhiwa.
Ukuzinza kwesikhathi eside kwesakhiwo esingenamanzi se-luminaire sihlobene eduze nomklamo wayo, ukusebenza kwempahla yesibani ekhethiwe, ukunemba kokucubungula, nobuchwepheshe bokuhlanganisa.
5, Mayelana Nento Engangeni Manzi
Umklamo ongenamanzi wezinto ezibonakalayo ufakwe ngaphakathi futhi uvinjelwe amanzi ngokugcwalisa i-potting glue, futhi inhlanganisela phakathi kwezingxenye zesakhiwo esivaliwe ziboshwe nge-glue yokuvala, ukuze izingxenye zikagesi zingabi nomoya ngokuphelele futhi zifeze umsebenzi ongenamanzi wokukhanyisa kwangaphandle.
6, I-Potting Glue
Ngokuthuthukiswa kobuchwepheshe bezinto ezingangeni manzi, izinhlobo ezihlukahlukene nezinhlobo zeglue ezikhethekile zokubumba ziye zavela ngokuqhubekayo. Isibonelo, i-epoxy resin eguquliwe, i-polyurethane resin eguquliwe, ijeli ye-organic silica eguquliwe nokunye.
