ukuthuthuka okusheshayo komphakathi wanamuhla, ukusetshenziswa kwesibonisi se-LED kuya ngokuya kusabalala. Kodwa-ke, ukusebenza okungangeni manzi kwesibonisi se-LED nakho kudonse ukunaka okubanzi, ikakhulukazi kweisibonisi se-LED sangaphandle.Ingabe kukhona okwaziyo mayelana nesilinganiso sokungangeni kwamanzi kwesibonisi se-LED esivalekile? cailiang, njengengcwetiUmkhiqizi wesibonisi we-LED, izokwethula ulwazi olungangeni manzi lwesibonisi se-LED ngokuningiliziwe kuwe.
Ukuhlukaniswa kwebanga elingangeni manzi kwesibonisi se-LED sangaphandle:
Isigaba sokuvikela sesibonisi yi-IP54, i-IP wuhlamvu lokumaka, inombolo engu-5 iyidijithi yokuqala yokumaka futhi u-4 uyidijithi yesibili yokumaka. Idijithi yokuqala yokumaka ikhombisa izinga lokuvikela othintana naye kanye nezinga lokuvikela into yangaphandle, kanti idijithi yesibili yokumaka ikhombisa izinga lokuvikela lingangeni manzi. Kufanele kuqashelwe ikakhulukazi ukuthi idijithi yesici sesibili ngemva kwe-IP, 6 nangaphansi, ukuhlolwa kuya ngokuya kuqina njengoba idijithi iba nkulu. Ngamanye amazwi, izibonisi ze-LED ezimakwe ngokuthi i-IPX6 zingaphumelela ekuhlolweni kwe-IPX5, IPX4, IPX3, IPX2, IPX1, ne-IPX0 ngesikhathi esisodwa. futhi ngaphansi. Ngamanye amazwi, ukumakwa kwe-IPX7 noma ukumakwa kwe-IPX8 akusho ukuthi kuphinde kuhambisane nezidingo ze-IPX6 ne-IPX5. Izibonisi ze-LED ezihlangabezana kanye nezidingo ze-IPX7 ne-IPX6 zingalebula ngokuthi IPX7/IPX6
Izibonisi ze-LED zangaphandle ezingenamanzi zibalulekile:
Okokuqala, izibonisi zangaphandle zidinga ukubhekana nezindawo ezinomswakama, ngakho-ke izinyathelo ezisebenzayo zokungangeni kwamanzi kanye nokugcinwa okujwayelekile kuyadingeka. Ikakhulukazi phakathi nenkathi yemvula, ukuqinisekisa ukuthi isibonisi sivalwe kahle futhi sifakiwe kunganciphisa kakhulu amathuba okungena kwamanzi. Ukususa uthuli njalo ebusweni besibonisi akusizi nje ukukhipha ukushisa, kodwa futhi kunciphisa ukufiphala komhwamuko wamanzi.
Umswakamo esibonisini se-LED ungaholela ekuhlulekeni okuhlukahlukene kanye nokulimala kwezibani, ngakho-ke izinyathelo zokuvimbela esigabeni sokukhiqiza nokufaka zibaluleke kakhulu, futhi kufanele zifune ukugwema lezi zinkinga ngesikhathi sokuqala.
Empeleni, imvelo enomswakama ophezulu izokwenza ibhodi le-PCB, ukunikezwa kwamandla nezintambo nezinye izingxenye zesibonisi se-LED kube lula uku-oxidize nokugqwala, okuzoholela ekuhlulekeni. Ngenxa yalesi sizathu, ukukhiqizwa kufanele kuqinisekise ukuthi ibhodi PCB emva ukwelashwa anti-ukugqwala, ezifana enamathela upende ezintathu-ubufakazi; ngesikhathi esifanayo khetha ukunikezwa kwamandla aphezulu kanye nezintambo. Ibhokisi elikhethiwe elingangeni amanzi kufanele livalwe kahle ukuze kuqinisekiswe ukuthi isikrini okungenani sineleveli yokuvikela ye-IP65. Ngaphezu kwalokho, izingxenye Welding ziyakwazi ukugqwala, futhi kufanele kube isivikelo waqiniswa ikakhulukazi, kuyilapho uhlaka lula ukugqwala ukugqwala ukwelashwa.
Okwesibili, ngezinto ezahlukene zebhodi leyunithi, udinga ukusebenzisa i-coating engangeni manzi, lapha ngaphandleIsibonisi se-LED sangaphandle se-P3 esinemibala egcwelenjengesibonelo. Uma ucubungula ukwelashwa okungenamanzi kwesibonisi se-LED sangaphandle se-P3 esinemibala egcwele, qala ngokuqinisekisa ukuthi ibhodi leyunithi lilungiswe uzibuthe noma isikulufu. Ngokuvamile, ukulungisa izikulufu kunikeza imiphumela ezinzile, kuyilapho umphumela wokulungisa womazibuthe ubuthakathaka. Okulandelayo, hlola ukuthi ingabe ibhodi leyunithi lifakwe umsele ongenamanzi; uma ifakwe i-groove engenawo amanzi, ukuvinjelwa kwamanzi ohlangothini lwangaphambili ngeke kube yinkinga enkulu ngisho noma indlela yokulungisa uzibuthe isetshenziswa. Ngaphezu kwalokho, kubalulekile futhi ukunaka ukusebenza okungangeni kwamanzi kwendiza yangaphandle yesibonisi se-LED. I-backplane akufanele nje ibhekane nokuchithwa kokushisa, kodwa futhi idinga ukusebenza kahle kwamanzi. Lapho usebenzelana nephaneli yangemuva, ukunakwa okukhethekile kufanele kukhokhwe kukhono lokungangeni kwamanzi nokushisa kwephaneli ye-aluminium composite. Kunconywa ukuthi izimbobo zibhotshozwe ngaphansi kwephaneli yenhlanganisela ye-aluminium kusetshenziswa i-drill kagesi ukuze kumiswe izimbobo zokudonsa amanzi, okungasizi nje kuphela ukuvimbela amanzi, kodwa futhi kusize ukuchithwa kokushisa, ukuze kugcinwe ukusebenza okuhle kakhulu kwesibonisi.
Ngaphezu kwalokho, endaweni ethile yokwakha, umklamo wesakhiwo kufanele uhlanganise izici zokuvimbela amanzi kanye nokukhipha amanzi. Ngemva kokunqunywa kwesakhiwo, khetha izinto zomcu wokuvala ngezinga eliphansi lokuchezuka kokucindezelwa kanye nezinga eliphakeme lokuklebhula ukuze uvumelane nezici zesakhiwo. Ngokusekelwe ezakhiweni zezinto ezikhethiwe, klama indawo efanele yokuxhumana namandla okuthwala ukuze uqinisekise ukuthi uphawu lukhishwe ngokuqinile futhi lwakha isakhiwo esiminyene. Ukuvikelwa okugxilile kufanele futhi kuhlinzekwe emininingwaneni yokufaka nokuvinjelwa kwamanzi ukuze kugwenywe inkinga yokuqoqwa kwamanzi kwangaphakathi ngenxa yokukhubazeka kwesakhiwo phakathi nenkathi yemvula, ukuze kuqinisekiswe ukusetshenziswa okuzinzile kwesikhathi eside kwesibonisi.
Ukunakekelwa kwezibonisi ze-LED kubaluleke kakhulu ezindaweni ezinomswakama ophezulu nezinga lokushisa, ikakhulukazi uma umsebenzi wokukhipha umswakama uvulwa njalo. Ukuthi isibonisi sifakwe endlini noma ngaphandle, isu elingcono kakhulu lokuvikela umswakama ukugcina sisebenza njalo. Isibonisi sikhiqiza ukushisa uma sisebenza, okusiza ukuhwamulisa omunye umswakama, ngaleyo ndlela kunciphisa kakhulu ingozi yamasekhethi amafushane ngenxa yezimo zomswakama. Ngokuvamile, izibonisi ezisetshenziswa njalo zimelana kakhulu nemiphumela yomswakama kunezibonisi ezisetshenziswa kancane. Ochwepheshe bemboni batusa ukuthi izibonisi ze-LED zivulwe okungenani kanye ngeviki phakathi nesizini eswakeme, nokuthi izikrini zivulwe futhi zigcinwe zikhanya amahora angaphezu kwama-2 okungenani kanye ngenyanga.
