Into evikela amanziUhlalutyo lobugcisa lwezibane ze-LED zangaphandle
Izibane zokukhanyisa zangaphandle zidinga ukumelana novavanyo lwekhephu kunye neqhwa, 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. Izinto eziphathekayo zingenamanzi, ukwenzela ukuba xa imveliso yenziwe, indawo ye-potting glue yokutywina amacandelo ombane ishiywe, kwaye i-glue isetyenziselwa ukukhutshwa kwamanzi ngexesha lokudibanisa. Uyilo olubini olungenamanzi luyafumaneka kwiindlela ezahlukeneyo zemveliso, nganye ineengenelo zayo.
Izinto ezichaphazela ukusebenza kwamanzi kwezibane
1, ukukhanya kwe-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. Ukuguga kwejeli yeembiza ze-elektroniki kubangela ukuqhekeka. Umtya werabha wokutywina uyaguga kwaye ukhubazekile, kwaye kuya kubakho umsantsa. I-adhesive phakathi kwamalungu esakhiwo sele ikhulile, kwaye i-gap nayo yenziwe emva kokuba ukunamathela kuyancipha. Zonke ezi zingumonakalo kwisakhono sokukhusela amanzi kwi-luminaire ngokukhanya kwe-ultraviolet.
I-2, iqondo lokushisa eliphezulu neliphantsi
Ubushushu bangaphandle buhluka kakhulu yonke imihla. Ehlotyeni, ubushushu obuphezulu bezibane bunokunyuka bufike kuma-50-60° C, kwaye ubushushu buhla ukuya kwi-10-20 qC 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, ukwanda kwe-thermal kunye nokunciphisa
Ukwandiswa kwe-thermal kunye nokucutheka kwendlu yesibane: Ukutshintsha kweqondo lokushisa kubangela ukwanda kwe-thermal kunye nokucutha kwesibane. Izinto ezahlukeneyo (ezifana neglasi kunye neeprofayili ze-aluminium) zinee-coefficients zokwandiswa komgca ezahlukeneyo, kwaye izinto ezimbini ziya kususwa kwindawo edibeneyo. Inkqubo yokwandiswa kwe-thermal kunye ne-contraction iphinda iphindwe ngokuqhubekayo, kwaye ukufuduka okuhambelanayo kuphindwe ngokuqhubekayo, okulimaza kakhulu ukungabikho komoya kwesibane.
Ukwandiswa kwe-thermal yomoya yangaphakathi kunye nokucutha: Ukuxinana kwamathontsi amanzi kwiglasi yesibane engcwatyiweyo kunokubonwa rhoqo kumgangatho wesikwere, kwaye amathontsi amanzi angena njani kwisibane esizaliswe yiglue yokubumba? Esi sisiphumo sokuphefumula ngexesha lokwandiswa kwe-thermal kunye nokunciphisa.
I-4, isakhiwo sokungangeni manzi
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.
I-5, into engenamanzi
Uyilo olungenamanzi lwezinto eziphathekayo lufakwe kwi-insulated kunye nokungena kwamanzi ngokuzalisa i-potting glue, kunye nokudibanisa phakathi kweendawo ezivaliweyo zesakhiwo zibophelelwe yi-glue yokutywina, ukwenzela ukuba amacandelo ombane angabikho ngokupheleleyo kwaye umphumo wokungena kwamanzi wokukhanya kwangaphandle ufezekiswe.
6, iglue yokugalela
Ngokuphuhliswa kobuchwephesha bezinto ezingangeni manzi, iintlobo ezahlukeneyo kunye neempawu zeglue ezikhethekileyo zokubumba ziye zavela ngokuqhubekayo, umzekelo, i-epoxy resin eguquliweyo, i-polyurethane resin eguquliweyo, ijeli ye-silica eguquliweyo, kunye nokunye okunjalo. Iifomyula zeekhemikhali ezahlukeneyo, iipropati ezibonakalayo kunye neekhemikhali ze-rubber ye-potting, ezifana ne-elasticity, i-molecular structure stability, i-adhesion, i-anti-uV, ukumelana nobushushu, ukumelana nobushushu obuphantsi, ukugxotha amanzi kunye neempawu zokugquma, zihlukile.
Ukuqukumbela
Kungakhathaliseki ukuba i-structural waterproofing okanye i-waterproofing yezinto eziphathekayo, ekusebenzeni okuzinzile kwexesha elide kunye nesantya esisezantsi sokungaphumeleli kokukhanyisa kwangaphandle, uyilo olulodwa olungenamanzi kunzima ukufezekisa ukuthembeka okuphezulu kakhulu, kunye nobungozi obufihliweyo obufihliweyo bokuphuma kwamanzi kusekho.
Ngoko ke, ukuyila kwezibane ze-LED zangaphandle eziphezulu kucetyiswa ukuba kusetyenziswe iteknoloji engenamanzi ukudibanisa iingenelo zokungangeni kwamanzi kunye netheknoloji yokukhusela amanzi ukuze kuphuculwe ukuzinza kwexesha elide lesekethe ye-LED. Ukuba izinto eziphathekayo zingenamanzi, zingongezwa kwi-respirator ukuphelisa uxinzelelo olubi. Uyilo lolwakhiwo olungangeni manzi lunokuthi luqwalaselwe ukwandisa i-potting, ukhuseleko oluphindwe kabini lokungena manzi, ukuphucula ukuzinza kokukhanya kwangaphandle kokusetyenziswa kwexesha elide, kunye nokunciphisa izinga lokungaphumeleli kokufuma.
