Mzere wowunikira wa LED tsopano ndi imodzi mwa nyali zomwe timagwiritsa ntchito nthawi zambiri.Nkhaniyi ikufotokoza makamaka zigawo zikuluzikulu za mizere yowunikira yomwe imagwiritsidwa ntchito kwambiri komanso momwe mungadziwire zingwe zowala zapamwamba.

High voltage nyali strip

Kupangidwa kwa chingwe cha nyali chapamwamba kwambiri

Chomwe chimatchedwa high-voltage light strip ndiye chowunikira chokhala ndi 220V mains power input.Inde, sikuloledwa kulumikiza mwachindunji AC 220V, komanso kuyenera kulumikiza mutu wamagetsi, monga momwe chithunzichi chili pansipa.

Kapangidwe ka mutu wa mphamvuyi ndi wosavuta kwambiri.Ndiwowonjezeranso mlatho, womwe umasintha mphamvu zama mains a AC kukhala magetsi osakhazikika a DC.Ma LED ndi ma semiconductors omwe amafunikira magetsi mwachindunji.

1, flexible nyali mbale mbale

Gawo lofunikira kwambiri ndikumamatira kuchuluka koyenera kwa mikanda ya nyali ya LED ndi zoletsa zoletsa zapano pa bolodi yosinthika.

Monga tikudziwira, mphamvu ya nyali imodzi ya LED ndi 3-5 V;Ngati mikanda yopitilira 60 imalumikizidwa palimodzi, voteji imatha kufika pafupifupi 200V, yomwe ili pafupi ndi magetsi amagetsi a 220V.Ndi kuwonjezera kwa kukana kwapano, mbale ya nyali ya LED imatha kugwira ntchito bwino mphamvu ya AC yokonzedwanso ikayatsidwa.

Mikanda yopitilira 60 ya nyali (zowona, pali 120, 240, yomwe imalumikizidwa molumikizana) imalumikizidwa palimodzi, ndipo kutalika kwake kuli pafupi ndi mita imodzi.Choncho, lamba wokwera kwambiri wamagetsi nthawi zambiri amadulidwa ndi mita imodzi.

Chofunikira chamtundu wa FPC ndikuwonetsetsa kuti chingwe chimodzi cha mizere yowala chili mkati mwa mita imodzi.Popeza chingwe chimodzi chomwe chilipo nthawi zambiri chimakhala pamlingo wa milliampere, makulidwe a mkuwa a flexplate yamphamvu kwambiri siwokwera kwambiri, ndipo gulu limodzi lagawo limodzi lidzagwiritsidwa ntchito kwambiri.

2. Kondakitala

Mawaya amalumikiza mita iliyonse ya mizere yowala.Mawaya akamathamanga, kutsika kwa magetsi a high-voltage DC kumakhala kochepa kwambiri poyerekeza ndi nyali za 12V kapena 24V low-voltage.Ichi ndichifukwa chake mzere wowunikira kwambiri wamagetsi amatha kugubuduza mamita 50, kapena ngakhale 100 metres.Mawaya ophatikizidwa kumbali zonse za lamba wa nyali wothamanga kwambiri amagwiritsidwa ntchito kutumiza magetsi othamanga kwambiri ku chingwe chilichonse cha mikanda yosinthasintha.

Ubwino wa waya ndi wofunikira kwambiri pamtundu wonse wamagetsi apamwamba kwambiri.Nthawi zambiri, mawaya apamwamba kwambiri opangira magetsi amapangidwa ndi mawaya amkuwa, ndipo gawo lagawoli ndi lalikulu, lomwe ndi lochulukirapo poyerekeza ndi mphamvu yonse ya mzere wowunikira kwambiri.

Komabe, zotsika mtengo komanso zotsika mtengo kwambiri zopangira magetsi sizidzagwiritsa ntchito mawaya amkuwa, koma mawaya a aluminiyamu okhala ndi mkuwa, kapena mawaya a aluminium mwachindunji, kapena mawaya achitsulo.Kuwala ndi mphamvu za mtundu woterewu wa bandi wowunikira mwachilengedwe sizokwera kwambiri, ndipo mwayi wa waya woyaka chifukwa chakuchulukira nawonso ndiwokwera kwambiri.Timalangiza anthu kupewa kugula mizere yopepuka yotere.

3, Potting zomatira

Kuwala kwamphamvu kwamagetsi kukuyenda pawaya ndi voteji yayikulu, zomwe zingakhale zoopsa.Insulation iyenera kuchitidwa bwino.Mchitidwe wamba ndikuyika mapulasitiki owoneka bwino a PVC.

Pulasitiki yamtunduwu imakhala ndi kuyatsa kwabwino, kulemera kopepuka, pulasitiki yabwino, kutsekereza komanso kutenthetsa kutentha.Ndi chitetezo choterechi, lamba wa nyali wapamwamba kwambiri angagwiritsidwe ntchito mosamala, ngakhale panja, ngakhale kuli mphepo kapena mvula.

Gwirani bolodi!Pano pali chidziwitso chozizira: chifukwa ntchito ya pulasitiki yowonekera ya PVC si mpweya, payenera kukhala kuchepetsedwa kwa kuwala kwa gulu la kuwala.Ili si vuto.Vuto ndiloti zimakhudzanso kutentha kwamtundu wamtundu wowala, womwe ndi mutu wamtundu wa kutentha kwa kutentha.Nthawi zambiri, imayandama 200-300K pamwamba.Mwachitsanzo, ngati mugwiritsa ntchito mkanda wa nyali wokhala ndi kutentha kwamtundu wa 2700K kuti mupange mbale ya mkanda wa nyali, kutentha kwamtundu mutadzaza ndi kusindikiza kumatha kufika 3000K.Mumapanga ndi kutentha kwa mtundu wa 6500K, ndipo imathamangira ku 6800K kapena 7000K mutasindikizidwa.
