Imiba echaphazela ukusebenza kwezibane ezingangeni manzi
Izixhobo zokukhanyisa zangaphandle kudala zimelana novavanyo lomkhenkce, ikhephu, ilanga elitshisayo, umoya, imvula, nombane, kwaye ixabiso liphezulu kakhulu, kwaye kunzima ukuqhaqha kunye nokulungiswa eludongeni lwangaphandle, kwaye kufuneka ukuhlangabezana neemfuno umsebenzi ozinzileyo wexesha elide. I-LED licandelo elithambileyo nelihloniphekileyo le-semiconductor. Ukuba iba manzi, i-chip iya kutsala ukufuma kwaye yonakalise i-LED, i-PcB kunye nezinye izinto. I-LED ifanelekile ukusebenza kwiqondo lokushisa elomileyo nelisezantsi. Ukuqinisekisa ukuba i-LED inokusebenza ngokuzinzileyo ixesha elide phantsi kweemeko ezinzima zangaphandle, uyilo lwesakhiwo esingenamanzi sesibane sibaluleke kakhulu.
Itekhnoloji yangoku engenamanzi yezibane kunye nezibane zohlulwe ikakhulu zibe ziindlela ezimbini: i-structural waterproofing and material material. Into ebizwa ngokuba yi-structural waterproofing ithetha ukuba emva kokuba iinqununu zesakhiwo ngasinye semveliso zidibene, sele zinomsebenzi ongenamanzi. Xa izinto eziphathekayo zingenamanzi, kuyimfuneko ukubeka eceleni i-potting glue ukutywina indawo yamacandelo ombane ngexesha loyilo lwemveliso, kwaye usebenzise izinto zeglue ukuze ufezekise ukukhutshwa kwamanzi ngexesha lokudibanisa. Uyilo olubini olungenamanzi lufanelekile kwimigca yeemveliso ezahlukeneyo, kwaye nganye ineenzuzo zayo.
1. Imitha ye-Ultraviolet
Imitha ye-Ultraviolet inempembelelo eyonakalisayo kumaleko wokugquma ucingo, iqokobhe elikhuselayo, iinxalenye zeplastiki, iglue yokubhaka, imicu yerabha etywiniweyo, kunye nezinto ezincamathelayo ezivezwe ngaphandle kwesibane.
Emva kokuba i-insulation layer ikhulile kwaye iqhekeke, umphunga wamanzi uya kungena kwisibane ngokusebenzisa izithuba kwi-core wire. Emva kokuguga kwegobolondo yesibane, ukugquma kumda wegobolondo kuqhekeka okanye kuqhume, kwaye kuya kubakho izikhewu. Emva kokuba igobolondo leplastiki sele likhulile, liya kuguqulwa kwaye liqhekeke. Ukuguga kwejeli yeembiza ze-elektroniki kuya kubangela ukuqhekeka. Umtya werabha wokutywina uyaguga kwaye ukhubazekile, kwaye kuya kubakho izithuba. I-adhesive phakathi kweengxenye zesakhiwo iguga, kwaye kuya kubakho izithuba emva kokunciphisa ukubambelela. Lo ngumonakalo wemitha ye-ultraviolet kwisakhono esingenamanzi sezibane.
2. Ukushisa okuphezulu kunye nokuphantsi
Ubushushu bangaphandle butshintsha kakhulu yonke imihla. Ehlotyeni, amaqondo obushushu angaphezulu kwezibane anokunyuka aye kuma-50℃60℃ emini aze ehle aye kwi-10⽞20 qC ebusuku. Ebusika, amaqondo obushushu angehla aye ngaphantsi kweqanda ngeentsuku ezinomkhenkce kunye nekhephu, kwaye umahluko wobushushu uyahluka kakhulu unyaka wonke. Izibane zangaphandle kunye nezibane kwindawo yokushisa kwehlobo eliphezulu, izinto eziphathekayo zikhawuleza ukuguga kunye nokuguqulwa. Xa amaqondo obushushu ehla ngaphantsi kwe-zero, iinxalenye zeplastiki ziba brittle, okanye ziqhekeke phantsi koxinzelelo lomkhenkce nekhephu.
3. Ukwandiswa kwe-thermal kunye nokunciphisa
Ukwandiswa kweThermal kunye nokucutheka kweqokobhe lesibane: Ukutshintsha kobushushu kubangela ukuba isibane sande kwaye sinciphe. Izinto ezahlukeneyo (ezifana neglasi kunye ne-aluminium) zinee-coefficients ezahlukeneyo zokwandiswa komgca, kwaye izinto ezimbini ziya kutshintsha kwi-joint. Inkqubo yokwandiswa kwe-thermal kunye ne-contraction iphinda iphindwe nge-cyclically, kwaye ukufuduka okuhambelanayo kuya kuphinda kuphindwe ngokuqhubekayo, okulimaza kakhulu ukuqina komoya kwesibane.
Umoya wangaphakathi uyanda ngobushushu kwaye ucutheka ngokubanda: Amathontsi amanzi akwiglasi yesibane esingcwatyiweyo ngokufuthi anokubonwa emhlabeni wesikwere, kodwa amathontsi amanzi angena njani kwizibane ezizaliswe yiglu yokugalela? Esi sisiphumo sokuphefumla xa ubushushu busanda kunye neekontraki ezibandayo. Xa iqondo lobushushu linyuka, phantsi kwesenzo soxinzelelo olukhulu olubi, umoya ofumileyo ungena ngaphakathi kumzimba wesibane ngokusebenzisa izikhewu ezincinci kwizinto zomzimba wesibane, kwaye udibana neqokobhe lesibane sobushushu obuphantsi, ujiya ube ngamathontsi amanzi kwaye uqokelele. Emva kokuba iqondo lokushisa lincitshisiwe, phantsi kwesenzo soxinzelelo olulungileyo, umoya ukhutshwa kumzimba wesibane, kodwa amaconsi amanzi asaqhotyoshelwe kwisibane. Inkqubo yokuphefumula yokutshintsha kweqondo lokushisa iphinda iphindwe yonke imihla, kwaye amanzi amaninzi aqokelela ngaphakathi kwezibane. Utshintsho olubonakalayo lokwandiswa kwe-thermal kunye nokucutha kwenza uyilo lokungangeni kwamanzi kunye nokuqina komoya kwezibane ze-LED zangaphandle zibe yinjineli yenkqubo enzima.
