Ulwazi olusisiseko lwesibane se-LED sangaphandle singenamanzi
Izixhobo zokukhanyisa zangaphandle zidinga ukujamelana novavanyo lweqhwa kunye nekhephu, umoya kunye nombane, kwaye iindleko ziphezulu. Ngenxa yokuba kunzima ukulungiswa eludongeni lwangaphandle, kufuneka luhlangabezane neemfuno zomsebenzi ozinzileyo wexesha elide. I-LED licandelo elithambileyo le-semiconductor. Ukuba imanzi, i-chip iya kutsala ukufuma kwaye yonakalise i-LED, i-PcB kunye nezinye izinto. Ngoko ke, i-LED ifanelekile ukomisa kunye nokushisa okuphantsi. Ukuqinisekisa ukusebenza okuzinzile kwexesha elide le-LED phantsi kweemeko ezinzima zangaphandle, ukwakhiwa kwesakhiwo esingenamanzi kwezibane kubaluleke kakhulu.
Okwangoku, itekhnoloji yokungena manzi yezibane ihlulwe kakhulu ibe ziindlela ezimbini: ukukhuselwa kwamanzi kwisakhiwo kunye nokuthintela amanzi. Into ebizwa ngokuba yi-structural waterproofing kukuba emva kokudibanisa amacandelo ahlukeneyo okwakhiwa kwemveliso, kuye kwangenamanzi. Isixhobo esingenamanzi sisikhundla secandelo lombane elitywiniweyo xa imveliso yenziwe. Izinto zeglue zisetyenziselwa ukuthintela amanzi ngexesha lokudibanisa.
Izinto ezichaphazela ukusebenza kwamanzi kwezibane
1, i-Ultraviolet
Imitha ye-Ultraviolet inempembelelo eyonakalisayo kwi-insulation yocingo, i-coating yangaphandle ekhuselayo, iinxalenye zeplastiki, iglue yokubumba, umcu werabha wokutywina kunye ne-adhesive evezwe ngaphandle kwesibane.
Emva kokuba umaleko we-insulation we-wire ukhulile kwaye uqhekeke, umphunga wamanzi uya kungena ngaphakathi kwesibane ngokusebenzisa i-gap ye-core core. Emva kokuba ukugquma kwendlu yesibane kugugile, ukugubungela kumda we-casing kuqhekezwe okanye kuhlanjululwe, kwaye i-gap ingenzeka. Emva kweminyaka yobudala beplastiki, iya kukhubaza kwaye iqhekeke. I-Electron potting colloids inokuqhekeka xa ikhulile. Umtya werabha wokutywina uyaguga kwaye ukhubazekile, kwaye kuya kubakho umsantsa. I-adhesive phakathi kwamalungu esakhiwo sele ikhulile, kwaye i-gap nayo yenziwe emva kokuba amandla okubambelela athotywe. Zonke ezi zingumonakalo kwisakhono sokungangeni manzi kwesibane.
2, Ubushushu obuphezulu kunye nePhantsi
Ubushushu bangaphandle buhluka kakhulu yonke imihla. Ehlotyeni, ubushushu obuphezulu bezibane bunokunyuka bufike kuma-50-60 °C, kwaye ubushushu behla ukuya kwi-10-20 ℃ ngokuhlwa. Amaqondo obushushu ebusika kunye nekhephu anokwehla aye ngaphantsi kweqanda, kwaye umahluko wobushushu utshintsha kakhulu unyaka wonke. Ukukhanya kwangaphandle kwindawo yokushisa ephezulu ehlobo, izinto eziphathekayo zikhawuleza ukuguga ukuguga. Xa ubushushu buhla ngaphantsi kwe-zero, iinxalenye zeplastiki ziba brittle, phantsi koxinzelelo lomkhenkce kunye nekhephu okanye ukuqhekeka.
I-3, Ukwandiswa kweThermal kunye nokuNcitshiswa
Ukwandiswa kwe-thermal kunye nokucutheka kwendlu yesibane: Ukutshintsha kweqondo lokushisa kubangela ukwanda kwe-thermal kunye nokucutha kwesibane. I-coefficient yokwandiswa komgca wezinto ezahlukeneyo zihluke, kwaye izinto ezimbini ziya kususwa kwindawo edibeneyo. Inkqubo yokwandiswa kwe-thermal kunye ne-contraction iphinda iphindwe ngokuqhubekayo, kwaye ukufuduka okuhambelanayo kuphinda kuphindwe ngokuqhubekayo, okulimaza kakhulu ukuqina komoya kwesibane.
4, Ulwakhiwo olungangenwa ngamanzi
Iiluminaires ezisekwe kuyilo lwesakhiwo olungangenwa manzi kufuneka zidityaniswe ngokuqinileyo kunye ne-silicone yokutywina iringi. Isakhiwo se-casing yangaphandle sichaneke ngakumbi kwaye sinzima. Ngokuqhelekileyo kulungele izibane ezinkulu, ezifana nezibane ze-strip, izibane zesikwere kunye nesetyhula, njl.
Nangona kunjalo, ulwakhiwo loyilo olungenamanzi lwe-luminaire luneemfuno eziphezulu zokulungisa, kwaye imilinganiselo yecandelo ngalinye kufuneka ifaniswe ngokuchanekileyo. Kuphela izinto ezingenamanzi ezinokuqinisekiswa ngezinto ezifanelekileyo kunye nokwakhiwa.
Uzinzo olude lwesakhiwo esingenamanzi se-luminaire sisondelelene nokuyila kwayo, ukusebenza kwezinto ezikhethiweyo zesibane, ukuchaneka kokucubungula, kunye nobuchwepheshe bendibano.
5, Malunga neMathiriyeli yokungangeni manzi
Uyilo olungenamanzi lwezinto eziphathekayo lufakwe kwi-insulated kwaye luvalwe ngamanzi ngokuzalisa i-potting glue, kunye nokudibanisa phakathi kweengxenye zesakhiwo ezivaliweyo zibophelelwe yi-glue yokutywina, ukwenzela ukuba amacandelo ombane aphephe ngokupheleleyo kwaye afezekise umsebenzi ongenamanzi wokukhanya kwangaphandle.
6, Potting Glue
Ngophuhliso lwetekhnoloji yezinto ezingangeni manzi, iintlobo ezahlukeneyo kunye neempawu zeglue ezikhethekileyo zokubumba ziye zavela ngokuqhubekayo. Ngokomzekelo, i-epoxy resin eguquliweyo, i-polyurethane resin eguquliweyo, ijeli ye-silica eguquliweyo kunye nokunye.
