Kodi ndi zinthu ziti zomwe ziyenera kuchitidwa powonetsa kuwala kwa LED panja?
Kodi ndi zinthu ziti zomwe ziyenera kuchitidwa powonetsa kuwala kwa LED panja?Pogwiritsa ntchito, chifukwa cha malo osiyanasiyana, nthawi zambiri amakhudzidwa ndi nyengo yoopsa monga kutentha, mphepo yamkuntho, mvula yamkuntho, bingu ndi mphezi.Kuti chinsalu chowonetserako chitetezeke panyengo yamvula, kodi tiyenera kusamala chiyani?
1. Anti-high kutentha
Chiwonetsero cha LED chowunikira panja nthawi zambiri chimakhala ndi malo akulu, chimadya mphamvu zambiri panthawi yofunsira, ndipo kutentha kofananirako kumakhalanso kwakukulu.Kuphatikiza apo, kutentha kwakunja ndikwambiri.Ngati vuto la kutaya kutentha silingathe kuthetsedwa panthawi yake, zikhoza kuyambitsa bolodi la dera.Mavuto monga kutentha ndi dera lalifupi.Popanga, onetsetsani kuti bolodi yowonetsera ili bwino, ndipo yesani kusankha chopanda kanthu popanga chotengeracho kuti chithandizire kutulutsa kutentha.Mukayika, malinga ndi momwe makhazikitsidwira, sungani chiwonetsero cha kuwala kwa LED pamalo abwino olowera mpweya wabwino, ndikuwonjezera zida zozizirira pachiwonetsero pakafunika kutero, monga kuyika choziziritsa mpweya kapena fani mkati kuti chiwonetserochi chizichotsa kutentha.
2. Anti-typhoon
Malo oyikapo ndi njira yokhazikitsira mawonedwe akunja a kuwala kwa LED ndizosiyana, monga mtundu wa mosaic, mtundu wa mzati, mtundu wopachikika, ndi zina zotero. pali zofunikira zokhwima pazitsulo zonyamula katundu zowonetsera.Gulu la engineering liyenera kupanga ndikukhazikitsa motsatira muyezo wa anti-typhoon level, ndipo panthawi imodzimodziyo kukhala ndi luso linalake loletsa zivomezi kuwonetsetsa kuti chiwonetsero cha LED cha mtengo wowala sichigwa ndikupangitsa kuvulala ndi zoopsa zina. .
3. Chitetezo cha mvula
Kum'mwera kuli mvula yambiri, kotero kuti chiwonetsero cha kuwala kwa LED chiyenera kukhala ndi chitetezo chokwanira chamadzi kuti chipewe kukokoloka kwa mvula.M'malo ogwiritsira ntchito panja, chiwonetsero cha kuwala kwa LED chiyenera kufika pa mlingo wa IP65 chitetezo, gawoli liyenera kutsekedwa ndi guluu, bokosi lopanda madzi liyenera kusankhidwa, ndipo gawo ndi bokosi ziyenera kugwirizanitsidwa ndi mphete ya rabara yopanda madzi.
4. Chitetezo cha mphezi
Ngati chowunikira chakunja cha LED sichili mkati mwachitetezo cha mphezi cholunjika cha nyumba zazitali zapafupi, ndodo yamphezi iyenera kuyikidwa pamwamba kapena pafupi ndi chitsulo chowonetsera;Mzerewu uli ndi chipangizo chotetezera mphezi.Panthawi imodzimodziyo, makina opangira magetsi a chipinda cha makompyuta amaperekedwa ndi chitetezo cha 3-level mphezi.
