FAQ
Kodi ubwino waukulu wa kuyitanitsa magetsi a LED ambiri ndi uti?
Kuyitanitsa zinthu zambiri kumachepetsa mtengo pa chinthu chilichonse ndipo kumatsimikizira kuti zinthuzo ndi zabwino nthawi zonse. Kumathandiza kuti njira zogulira zinthu zikhale zosavuta komanso kuchepetsa mavuto okhudzana ndi kayendedwe ka zinthu. Ogulitsa amathanso kukambirana bwino za zinthu monga chitsimikizo chowonjezera kapena njira zina zosinthira zinthu, akamayitanitsa zinthu zambiri.
Kodi ogulitsa angatsimikizire bwanji kuti magetsi a LED ndi abwino?
Ogulitsa ayenera kutsimikizira ziphaso monga UL, ETL, kapena RoHS. Ayeneranso kuwunikanso umboni wa makasitomala ndikupempha zitsanzo za zinthu. Kuwunika miyeso monga kutulutsa kwa lumen, CRI, ndi nthawi ya chitsimikizo kumatsimikizira kuti magetsi akukwaniritsa miyezo yogwira ntchito komanso yolimba.
Kodi magetsi a LED ndi oyenera malo ogulitsira panja?
Inde, magetsi a LED okhala ndi ma rating osalowa madzi monga IP65 kapena IP68 ndi abwino kwambiri kugwiritsidwa ntchito panja. Ma rating awa amateteza ku chinyezi, fumbi, komanso nyengo yoipa. Ogulitsa amatha kuwagwiritsa ntchito ngati zizindikiro, kuunikira kokongoletsa, kapena kuwonetsa panja.
Kodi magetsi a LED angasinthidwe malinga ndi zosowa za ogulitsa?
Ogulitsa monga Ninghai County Yufei Plastic Electric Appliance Factory amapereka njira zosinthira. Ogulitsa amatha kupempha kutalika, mitundu, kapena milingo yotetezera madzi. Zinthu zomwe zingakonzedwe ndi zosankha zomwe zingachepetsedwe zimawonjezera kusinthasintha kwa ntchito zapadera zogulitsa.
Kodi magetsi a LED amathandiza bwanji kuti zinthu ziyende bwino?
Magetsi a LED amagwiritsa ntchito mphamvu zochepa ndipo amakhala nthawi yayitali kuposa magetsi achikhalidwe. Amachepetsa mpweya woipa womwe umawononga chilengedwe komanso zinyalala. Zipangizo zosamalira chilengedwe, monga zinthu zopanda mercury, zimapangitsa kuti zikhale zotetezeka ku chilengedwe komanso zobwezerezedwanso.
