Kwinkqubo yokwenza izigqibo zokuthenga imicu yokukhanya ye-LED, ukukhetha phakathi kombane ophezulu kunye nombane ophantsi yingxaki engundoqo engenakuphepheka. Abasebenzisi abaninzi badidekile: Ngaba ukufakwa kwemicu yokukhanya ephezulu kulula? Ngaba ukhuseleko lwemicu yokukhanya ephantsi luphezulu ngokwenene? Ungakanani umahluko kwiindleko zokufakela phakathi kwezi zimbini? Enyanisweni, akukho kuphakama okanye ukungathobeli ngokupheleleyo phakathi kwezi ntlobo zimbini zemicu yokukhanya. Umahluko oyintloko ukwimilinganiselo emithathu: ukhuseleko, iindleko zokufakela, kunye neemeko ezifanelekileyo. Eli nqaku, ngokusebenzisa iinkcazo ezicacileyo nezincinci, likunceda ucacise ngokupheleleyo umahluko phakathi kwezi zimbini ukusuka ekuqondeni okusisiseko ukuya ekuthelekiseni okunzulu, uze emva koko uye ekukhetheni okusekelwe kwimeko, ukuhambelana ngokuchanekileyo neemfuno zeprojekthi.
Iinkcazo eziphambili zei-voltage ephezulukunye nemicu yokukhanya ye-LED ene-voltage ephantsi:
●Into ephambili kwiintambo zokukhanya ze-LED ezine-voltage ephezulu kukuba i-voltage yazo yokufaka ngamandla e-220V, nto leyo esusa isidingo see-transformers ezongezelelweyo kwaye zivumela ukuba ziqhagamshelwe ngqo kwiintambo zombane zasekhaya okanye zobunjineli. Ulwakhiwo lwayo lupakishwe kakhulu ngeebhodi ze-PCB eziqinileyo, kwaye ii-LED beads zicwangciswe kakuhle. Iinkcukacha eziqhelekileyo ziyi-12W-24W ngemitha, kunye nokukhanya okuzinzileyo, okwenza ukuba ifaneleke ukufakwa kwiindawo ezinkulu nezikude. Iintambo zethu zokukhanya ezine-voltage ephezulu zinoyilo lwe-drive yokukhusela i-surge, olumelana ngempumelelo nokuguquguquka kwe-voltage. Zikwanayo ne-IP65 engangeni manzi, nto leyo ebenza bafaneleke kwiimeko zokukhanya zangaphandle ezisisiseko.
●I-voltage yokufaka yemigca yokukhanya ye-LED ene-voltage ephantsi yi-12V okanye i-24V DC voltage. Kufuneka zisetyenziswe kunye ne-transformer. Kuphela emva kokuguqula amandla e-220V mains abe ngamandla e-DC ane-voltage ephantsi nge-transformer apho banokusebenza khona. Izinto zayo ziibhodi ze-PCB eziguquguqukayo kakhulu, ezinokugotywa kwaye zinqunyulwe, zilungele ukufakwa kwesimo esintsonkothileyo. Iinkcukacha eziqhelekileyo yi-5W-20W ngemitha, enokukhanya okuthambileyo kunye nokhuseleko olubalaseleyo. Zonke ii-strips zethu zokukhanya ezine-voltage ephantsi zisebenzisa izisombululo ze-drive zangoku eziqhubekayo, ezibonisa ukuncitshiswa kokukhanya okucothayo kunye nobomi obude. Zikwaxhasa amanqanaba angangenisi manzi enziwe ngokwezifiso (IP44-IP67), egubungela iimeko ezahlukeneyo ezifana nokusetyenziswa kwasekhaya kunye norhwebo.
Ukhuseleko – Imicu yokukhanya ene-voltage ephantsi ineengenelo ezibalulekileyo, ngelixa ene-voltage ephezulu ifuna ulawulo oluqinileyo kunye nokhuseleko:
①Izikhonkwane zezibane ze-LED ezine-voltage ephezulu: Zineengozi eziphezulu zokhuseleko kunye neemfuno ezingqongqo zokhuseleko
●- Umngcipheko wokutshayiswa ngumbane: Ukudibana ngqo nombane ophezulu we-220V kunokubangela iingozi zokutshayiswa ngumbane ngokulula, ingakumbi kwiindawo ezimanzi (ezifana nezindlu zangasese, iintsuku zemvula zangaphandle), umngcipheko uphindaphindeka kabini.
●- Ingozi yomlilo: Ukuba iingcingo ziyaguga, amalungu ayakhululeka okanye agcwele kakhulu, kunokwenzeka ukuba kubekho imijikelo emfutshane kunye nobushushu obugqithisileyo, nto leyo enokubangela umlilo.
●- Iimfuneko zokhuseleko: Unyango lokufakwa kwe-insulation kufuneka lwenziwe kakuhle. Iijoyinti kufuneka zivalwe ngee-terminals ezinikezelweyo zokungena kwamanzi. Ukusetyenziswa ngaphandle, kufuneka kukhethwe umgangatho wokungena kwamanzi we-IP65+, kwaye abasebenzi bokufakela kufuneka babe neziqinisekiso zombane.
②Izikhonkwane zezibane ze-LED ezine-voltage ephantsi: Ngenxa yokuba zikhuselekile kakhulu, ziyasebenza kwiimeko ezahlukeneyo.
●- Akukho mngcipheko wokothuka ngombane: Isebenza nge-12V/24V low voltage, ayizukubangela ukothuka ngombane nokuba ichukunyiswe ngqo. Ifanelekile kumagumbi abantwana, kwiindawo zokugcina abantwana, kumagumbi okuhlambela nakwezinye iindawo ezichukunyiswa rhoqo okanye ezinomswakama ophezulu.
●- Umngcipheko ophantsi womlilo: Nge-voltage ephantsi kunye neempawu zamandla aphezulu, umbane we-drive uya kuzikhusela ngokuzenzekelayo (ukucima amandla/umda wamandla) xa umgca ugcwele kakhulu ukuthintela ukugqithisa kakhulu.
●- Ukhuseleko oluguquguqukayo: Ubushushu obuqhelekileyo buyanele ukusetyenziswa ngaphakathi. Kwiimeko ezimanzi okanye ngaphandle, kuphela inqanaba elingangeni manzi leumgca wokukhanyangokwayo kufuneka iphuculwe. Umlinganiselo wokufakelwa uphantsi kwaye ingasetyenziswa ngaphandle kweengcali zombane.
Iindleko zokufakela – I-voltage ephezulu igcina amandla kwisigaba sokuqala, i-voltage ephantsi inika ixabiso lexesha elide:
①Ixabiso lokuqala lokuthenga: Imicu yokukhanya ene-voltage ephezulu ineengenelo ezingaphezulu
●Iziqwenga zezibane ze-LED ezine-voltage ephezulu: Akukho transformer eyongezelelweyo efunekayo ukuthengwa. Ixabiso ngemitha nganye limalunga ne-15 ukuya kwi-30RMB. Xa uthenga ngomlinganiselo omkhulu, utyalo-mali lokuqala luphantsi kakhulu.
●Izilayidi zezibane ze-LED ezine-voltage ephantsi: Kufuneka i-transformer eyongezelelweyo (i-12V/24V constant current drive). Ixabiso leyunithi yomqhubi limalunga ne-50 ukuya kwi-200RMB (ehlelwe ngamandla). Kunye nomcu wokukhanya ngokwawo (20 ukuya kwi-40RMB ngemitha), iindleko zokuqala zokuthenga ziphezulu nge-20% ukuya kwi-40% kunezo zine-voltage ephezulu.
②Iindleko zomsebenzi wokufakelwa: Uxinzelelo oluphezulu lufuna ulwakhiwo lobuchwephesha, ngelixa uxinzelelo oluphantsi lungenaxhala ngakumbi
●Izikhonkwane zezibane ze-LED ezine-voltage ephezulu: Kufuneka iingcali zombane ezingoochwephesha ukuze zifake iintambo kwaye ziqhagamshele, zigqunywe kwaye zikhuselwe ngokufanelekileyo. Xa zibalwa ngokusekelwe kufakelo lweemitha ezili-100, iindleko zomsebenzi zimalunga ne-800 ukuya kwi-1,200RMB.
●Izilayidi zezibane ze-LED ezine-voltage ephantsi: Ucingo lulula. Qhagamshela nje izilayidi zezibane kumqhubi uze uqhagamshele kumbane we-mains. Kwanabaqalayo banokuyisebenzisa. Ixabiso lomsebenzi wokubeka iimitha ezili-100 limalunga ne-300 ukuya kwi-500RMB. Ungazizenzela ngokwakho ukuze wonge iindleko zomsebenzi.
③Iindleko zokulungisa kamva: Umbane ophantsi uphila ixesha elide, nto leyo eyenza ukugcinwa kube lula ngakumbi:
●Izilayidi zezibane ze-LED ezine-voltage ephezulu: Ngenxa ye-voltage ephezulu, iisekethe kunye nee-LED beads zilungele ukuguga, zihlala ixesha elide malunga neminyaka emi-3 ukuya kwemi-5. Iindleko zokutshintsha iisekethe kunye nokulungisa iimpazamo kwinqanaba lokugqibela ziphezulu, kwaye kunzima ukuzisombulula.
●Izilayidi zezibane ze-LED ezine-voltage ephantsi: Zisebenzisa i-drive yangoku engaguqukiyo, enokukhanya okucothayo kunye nobomi obuhlala malunga neminyaka emi-5 ukuya kweyesi-8 (iimveliso zethu ziza newaranti yeminyaka emi-3-5). Kwinqanaba lokugqibela, kufuneka ukujonga umqhubi rhoqo kuphela, okubangela iindleko zokulungisa eziphantsi kunye nokufumanisa iimpazamo ngokulula (ubukhulu becala iingxaki zomqhubi, zitshintshe ngokuthe ngqo).
Beka phambili iimeko apho kukhethwa khona imicu yokukhanya ye-LED ene-voltage ephezulu:
①Izibane ezinkulu zobunjineli bangaphandle (indawo engenanto yokuchukumisa, eyomileyo)
②Iiprojekthi zokukhanyisa zexeshana okanye zexabiso eliphantsi
Beka phambili iimeko apho kukhethwa khona imicu yokukhanya ye-LED ene-voltage ephantsi:
①Iimeko zokuhombisa ikhaya (Ukhuseleko kuqala
②Iimeko zoshishino (zigxininisa amava kunye nokhuseleko
③Iindawo ezijikelezileyo ezifumileyo/ezihambayo
Amanqaku amane abalulekileyo omele uwaphephe xa uthenga:
①Xa ukhetha umgangatho ophantsiimicu yokukhanya ene-voltage ephezuluNgenxa yexabiso eliphantsi, qiniseka ukuba uyayiqonda “isiqinisekiso se-3C” kwaye uphephe iimveliso ezingenazo izikhuselo zokukhusela ubushushu.
②Kwii-light strips ezine-voltage ephantsi, umgangatho womqhubi mawungananzwa. Abaqhubi abakumgangatho ophantsi banokubangela ukuba ii-light strips zikhanye kwaye zikhawuleze ukukhanya. Kucetyiswa ukuba ukhethe abaqhubi be-brand constant current kuqala.
③Didanisa umgangatho ongangeni manzi. Kwiimeko zangaphandle, kuyimfuneko ukuchaza ngokucacileyo umgangatho ongangeni manzi womgca wokukhanya (IP65+) ukuthintela ukukhukuliseka kwemvula.
④Khetha uhlobo ngokungakhathaliyo ngaphandle kokuqwalasela imeko yokufakela. Ziphephe iziqwenga zokukhanya ezine-voltage ephezulu kwiimeko ezimanzi okanye ezichukumisekayo kwaye nika ingqalelo kwezo zine-voltage ephantsi.
