Kufunika koteteza chitetezo cha LED Outdoor Lighting
Kuwomba kwa mphezi ndi zinthu zotulutsa ma electrostatic zomwe nthawi zambiri zimanyamula ma volts mamiliyoni ambiri kuchokera kumitambo kupita pansi kapena kupita kumtambo wina. Pakutumiza, mphezi imapanga minda yamagetsi yamagetsi mumlengalenga, imapangitsa ma volts (mafunde) masauzande ku chingwe chamagetsi ndikutulutsa mafunde omwe amayenda mtunda wa makilomita mazana ambiri. Izi nthawi zambiri zimachitika pa mawaya omwe ali panja, monga magetsi a mumsewu. Zida monga magetsi apamsewu ndi masiteshoni amatulutsa mafunde. Module yoteteza mawotchiyo imayang'anizana mwachindunji ndi kusokonezeka kwapang'onopang'ono kuchokera ku mzere wamagetsi kumapeto kwa dera. Imasamutsa kapena kuyamwa mphamvu ya mawotchi, kuchepetsa chiopsezo cha ma surges kupita ku mabwalo ena ogwira ntchito, monga mayunitsi amagetsi a AC/DC muzowunikira za LED.
Kwa mphamvu yamagetsi yakunja ya LED, malo ogwiritsira ntchito amatsimikizira kuti chitetezo cha mphezi ndi chizindikiro chofunikira choyezera momwe ntchito yake ikuyendera. Chifukwa chake, kapangidwe ka chitetezo cha mphezi kuyenera kuganiziridwa pamagetsi akunja a LED. Kutengera gawo loteteza mphezi la kulowetsa kwa AC kwa gwero lamagetsi lodziwika bwino ndi mainjiniya mwachitsanzo, kutetezedwa kwa mphezi kwa kulowetsa kwa AC kwamagetsi kumayamba chifukwa chotengera mphamvu zosakhalitsa zomwe zimabweretsedwa ndi kugunda kwa mphezi kapena kutulutsa mphamvu dziko lapansi kudzera m'njira yokonzedweratu. Pewani kukhudza kumbuyo kumapeto kwa magetsi.
Kwa magetsi a mumsewu wa LED, mphezi imapanga kukwera kochititsa chidwi pa chingwe chamagetsi. Kuthamanga kwa mphamvu kumeneku kumapangitsa kuti waya pawonjezeke, ndiko kuti, mafunde amphamvu. Kuwombako kumafalikira kudzera mu induction yotere. Dziko lakunja lili ndi mafunde. Mafundewa apanga nsonga pa sine wave mu mzere wotumizira wa 220V. Pamene nsonga imalowa mu kuwala kwa msewu, idzawononga dera la nyali ya msewu wa LED.
Nyali zamsewu zakhala zikuchitika kwa zaka zambiri. N’chifukwa chiyani tifunika kupeza chitetezo cha mphezi pa nyali za mumsewu? M'malo mwake, nyali zothamanga kwambiri za sodium ndi nyali zachikhalidwe za mercury zomwe zimagwiritsidwa ntchito m'mbuyomu zidapangidwa ndi mababu okwera kwambiri, omwe amakhala ndi chitetezo cha mphezi. M'zaka zaposachedwapa, nyali za LED zakhala zikudziwika kwambiri. Magetsi a LED amafunikira magetsi ochepa. Nthawi zambiri, magetsi amagwiritsidwa ntchito kutembenuza mphamvu ya AC kukhala mphamvu ya DC. Izi zimapangitsa kuti nyali ya mumsewu wa LED ikhale yopanda chitetezo cha mphezi, chifukwa chake gawo lachitetezo cha surge liyenera kupangidwira nyali zamsewu.
Chidziwitso: Muyezo wachitetezo cha mphezi cha US katatu
Mu US National Standards yomwe idatulutsidwa mu 2015, magawo atatu achitetezo cha mphezi adayambitsidwa. Chifukwa chake n’chakuti magiredi atatuwo ali chifukwa chakuti mafuko a Kum’maŵa ndi Kumadzulo ku United States ndi osiyana kwambiri. Migodi yapamwamba imatha kufika nthawi 30 mpaka 40, pamene migodi yochepa imakhala ndi nthawi imodzi kapena ziwiri. Choncho, milingo itatu ndi muyezo. 6kV, 10kV ndi 20kV. Izi ndizosinthanso kwa opanga zowunikira komanso maboma am'deralo. Maboma ang'onoang'ono atha kusankha kugwiritsa ntchito miyezo yoyenera malinga ndi momwe zinthu ziliri.
