Ukushaywa kombani kuyisenzakalo esivamile semvelo, ikakhulukazi ngesikhathi semvula. Umonakalo kanye nokulahlekelwa okubangelwa yiwo kulinganiselwa emakhulwini ezigidigidi zamaRandi ngenxaIzimpahla zamandla ezibani zasemgwaqweni ze-LEDminyaka yonke emhlabeni jikelele. Ukushaywa kombani kuhlukaniswa njengokuqondile nokungaqondile. Umbani ongaqondile ngokuyinhloko uhlanganisa umbani oqhutshwayo nowenziwe. Ngenxa yokuthi umbani oqondile uletha umthelela omkhulu wamandla kanye namandla okubhubhisa, izinsiza zamandla ezivamile azikwazi ukumelana nawo. Lesi sihloko sizoxoxa ngombani ongaqondile, ohlanganisa kokubili umbani oqhutshwayo nowenziwe.
Ukwanda okubangelwa ukushaywa kombani kuyigagasi lesikhashana, ukuphazamiseka kwesikhashana, futhi kungaba yi-voltage yokwanda noma i-surge current. Idluliselwa entanjeni kagesi eceleni kwemigqa kagesi noma kwezinye izindlela (umbani oqhutshwayo) noma ngokusebenzisa amasimu kagesi (umbani obangelwayo). Ukuma kwawo kwegagasi kubonakala ngokukhuphuka okusheshayo okulandelwa ukuwa kancane kancane. Lesi simo singaba nomthelela omubi kakhulu ekuhlinzekweni kwamandla, njengoba ukwanda okusheshayo kudlula kakhulu ukucindezeleka kukagesi kwezingxenye ezivamile ze-elekthronikhi, kuzilimaza ngqo.
Isidingo Sokuvikelwa Kombani Kwezibani Zemigwaqo ze-LED
Kumalambu emigwaqo e-LED, umbani ubangela ukukhuphuka kwemigqa yokunikezwa kwamandla kagesi. Lawa mandla okukhuphuka adala igagasi elingazelelwe emigqeni kagesi, eyaziwa ngokuthi i-surge wave. Ukukhuphuka kwegesi kudluliselwa ngale ndlela yokungenisa. Igagasi lokukhuphuka kwangaphandle lidala ukukhuphuka kwegagasi le-sine lomugqa wokudlulisela we-220V. Lokhu kukhuphuka kwegesi kungena ekukhanyeni komgwaqo futhi kulimaze isekethe yokukhanya kwesitaladi se-LED.
Kuma-power supply ahlakaniphile, noma ngabe ukushaqeka kwesikhashana okubangelwa ukukhuphuka kwejubane kungalimazi izingxenye, kungaphazamisa ukusebenza okuvamile, kubangele imiyalelo eyiphutha futhi kuvimbele ukunikezwa kwamandla ukuthi kusebenze njengoba kulindelekile.
Njengamanje, ngenxa yokuthi izibani ze-LED zinezidingo kanye nemikhawulo ngobukhulu bokunikezwa kwamandla, ukuklama ukunikezwa kwamandla okuhlangabezana nezidingo zokuvikelwa kombani ngaphakathi kwesikhala esilinganiselwe akulula. Ngokuvamile, indinganiso yamanje ye-GB/T17626.5 incoma kuphela ukuthi imikhiqizo ihlangabezane nezindinganiso zemodi yokuhlukanisa ye-2kV kanye nemodi evamile ye-4kV. Eqinisweni, lezi zincazelo azifiki kakhulu ezidingweni zangempela, ikakhulukazi ezisetshenzisweni ezindaweni ezikhethekile njengezikhumulo zamachweba nama-terminals, amafektri anemishini emikhulu ye-electromechanical eduze, noma ezindaweni ezivame ukushaywa umbani. Ukuze kuxazululwe le ngxabano, izinkampani eziningi zokukhanyisa emgwaqweni zivame ukwengeza i-standalone surge suppressor. Ngokufaka idivayisi yokuvikela umbani ezimele phakathi kokufakwayo kanye nomshayeli we-LED wangaphandle, usongo lokushaya kombani kumshayeli we-LED wangaphandle luyancishiswa, okuqinisekisa kakhulu ukuthembeka kokunikezwa kwamandla.
Ngaphezu kwalokho, kuneziningana ezibalulekile okufanele zicatshangelwe ngokufakwa nokusetshenziswa komshayeli ngendlela efanele. Isibonelo, ukunikezwa kwamandla kumele kusekelwe ngokuqinile ukuze kuqinisekiswe indlela eqondile yokuthi amandla okukhuphuka anyamalale. Izintambo zikagesi ezinikezelwe kufanele zisetshenziswe kumshayeli wangaphandle, kugwenywe imishini emikhulu kagesi eseduze ukuze kuvinjelwe ukukhuphuka ngesikhathi sokuqalisa. Umthwalo ophelele wezibani (noma izinsiza zikagesi) emgqeni ngamunye wegatsha kufanele ulawulwe kahle ukuze kugwenywe ukukhuphuka okubangelwa yimithwalo eminingi ngesikhathi sokuqalisa. Amaswishi kufanele ahlelwe ngendlela efanele, kuqinisekiswe ukuthi iswishi ngayinye ivuliwe noma ivaliwe ngendlela yesinyathelo ngesinyathelo. Lezi zinyathelo zingavimbela ngempumelelo ukukhuphuka kokusebenza, kuqinisekiswe ukusebenza okuthembekile kakhudlwana komshayeli we-LED.
UTIANXIANG ubone ukuvela kwe-Isibani sesitaladi se-LEDimboni futhi iqoqe ulwazi oluningi ekubhekaneni nezidingo zezimo ezahlukahlukene. Lo mkhiqizo unezindawo zokuvikela umbani ezakhiwe ngaphakathi futhi uphumelele isitifiketi sokuhlolwa kokuvikela umbani. Ungamelana nomthelela wesimo sezulu esinamandla sombani esijikelezweni, uvimbele umonakalo wemishini futhi uqinisekise ukuthi ukukhanya komgwaqo kusebenza kahle ngisho nasezindaweni ezivame ukuba nezimvula ezinkulu. Ungamelana nokuhlolwa kwezindawo zangaphandle eziyinkimbinkimbi zesikhathi eside. Izinga lokubola kokukhanya liphansi kakhulu kunesilinganiso semboni, futhi impilo yesevisi inde.
