Masiku ano, pali mitundu yambiri yamawonedwe a zowonetsera za LED , yomwe imasangalatsa makasitomala ambiri. Mawonetsedwe azamalonda a malonda amalembedwa m'minda yayikulu yamalonda. Komabe, zinthu zowonetserako za LED sizikugwirizana bwino, zomwe zimabweretsa mavuto azachitetezo pazenera la LED, ndipo moto ndi vuto lalikulu. Chifukwa chiyani kuwonetsera kwa LED kumagwira moto?
Choyamba, chingwe chamagetsi: mtundu wa chingwe pamsika chimasokonekera, ma waya ambiri amkuwa ndi mkuwa wokutira zotayidwa, mawonekedwe ake amawoneka ngati waya wamkuwa, chizolowezi chake ndi waya wa aluminium alloy; waya / chingwechi chimagwiritsidwa ntchito kwakanthawi, kwenikweni sichingagwiritsidwe ntchito pazogulitsa. Palinso kukayika kwamkuwa pamkuwa wamkuwa, kukayikira zazitsulo zosanjikiza, ndikukayikiranso za waya m'mimba mwake (zofunikira wamba ndizopitilira 1.2 mphamvu yayikulu yowonetsera). zoopsa. Tsopano ikuyambitsa masoka akulu.
Chachiwiri, magetsi: gwiritsani ntchito magetsi ocheperako, kapena malire ake oti mugwiritse ntchito mphamvu zowonjezera zamagetsi, zomwe zimapangitsa kuti pakhale mphamvu zochulukirapo zamagetsi (nthawi zambiri zimangokhala 70% yamphamvu zowonjezera zamagetsi), kenako chingwe chamagetsi chimakhala chotsika komanso kusokosera sikolimba, izi zitha kukhala zoyambitsa zobisika za apolisi;
Chachitatu, bolodi la PCB: data yake ndiyotsika, mkuwa ndiwowonda kwambiri, dongosololi ndilopanda pake, ndondomekoyi ndiyosauka, waya wamkuwa uli ndi ma burrs ndipo zochitika zina zidzakhala ndi dera lalifupi, lomwe limakhala gwero la ngozi yamoto;
Chachinayi, dongosolo lozizira. The anasonyeza LED zenera ndi tasked pa kutentha ndi vuto kutentha madyaidya ndikuledzera wobwezera funso loyamba la processing akumufuna. Ngati dongosolo loziziritsira mpweya ndilopanda tanthauzo, limapangitsa kuti fumbi lisonkhane pamtsinje waukulu wa zimakupiza, magetsi ndi bolodi lalikulu, zomwe zimapangitsa kuti kutentha kuzizire, kufalikira kwa zida zamagetsi, komanso kufa kwa magetsi fani, motero kuyambitsa alamu.
Chachisanu, ntchito ndi kukonza. Kumbali imodzi, woperekayo sanaphunzitsidwe mwadongosolo pakugula kasitomala, zomwe zimapangitsa kuti ntchito ziziyenda bwino. Mbali inanso ndikuti wopereka zowonetserayo sanachitepo zowonetsera zomwe zagulitsidwa, ndipo kukonza sikungakhale nthawi yeniyeni koyambirira, zomwe zimapangitsa kuti zisakhale zotheka kupanga nthawi yeniyeni.
Kaya magwiridwe antchito amoto akuwonetsedwa ndioyenera makamaka zokhudzana ndi zinthu ziwiri zomwe zimawonetsedwa pamoto ndi njira yomwe bokosi likuwonetsera. Apa, cholinga chake ndikuwunika zinthu zinayi zomwe zimapangitsa kuti chiwonetserochi chikuyatsa moto:
Chipangizo cha pulasitiki
Phukusi la pulasitiki ndi gawo lofunikira pazinthu zosagwira moto zowonetsera. Chifukwa imagwiritsidwa ntchito pachikuto cha chigawo cha unit unit, imagwiritsa ntchito PC + magalasi okhala ndi zotsekemera zamoto. Iwo osati ali lawi wamtundu uliwonse ntchito, komanso akhoza opunduka, Chimaona ndi losweka pansi kutentha ndi otsika kutentha ndi ntchito yaitali. Nthawi yomweyo, imagwiritsa ntchito guluu wosindikiza wabwino, womwe ungalepheretse bwino madzi amvula ochokera kumalo akunja kuti asalowe mkatikati, motero kupewa moto woyambitsidwa ndi dera lalifupi.
Waya chinthu
Kukulitsa kuwonetsera gawo lililonse la chiwonetserochi, kumachulukitsa mphamvu zamagetsi zomwe zimagwiritsidwa ntchito, ndikukweza zofunikira pakukhazikika kwa waya. Mwa zinthu zambiri zama waya, ndi waya wokha womwe umakwaniritsa muyeso wadziko lonse womwe ungagwiritsidwe ntchito kuonetsetsa kuti chitetezo chake ndi kukhazikika. Izi zikuyenera kukwaniritsidwa posankha: Choyamba, pachimake payenera kukhala chonyamulira cha waya wamkuwa. Chachiwiri, kulolerana kwapakati pamiyeso yama waya kumakhala koyenera. Pomaliza, kutchinjiriza ndi kutsalira kwa lawi kwa mphira wokutidwa wokulirapo uyenera kukwaniritsa muyezo.
Mphamvu yamagetsi
Mukamasankha magetsi, magetsi okha omwe ali ndi mbiri yabwino ya UL ndiye abwino kwambiri. Chifukwa kutembenuka kwake koyenera kumatsimikizira chitetezo ndi kukhazikika kwa katundu wamagetsi, imatha kugwira ntchito bwino ngakhale kutentha kwa chilengedwe chakunja kukutentha.
Zinthu zakunja zoteteza
Ndikofunikira kwambiri posankha mawonekedwe akunja otetezera owonetsera. Chifukwa chojambula cha aluminium-pulasitiki chazowonetserako panja sichimayatsa moto, chimatha msanga ndi kutentha komanso mvula ndi kuzizira, kotero kuti chimatha kulowa mthupi nthawi yayitali nyengo yachisanu, yomwe imabweretsa zamagetsi. Dera lalifupi m'chigawochi limayambitsa moto. Chifukwa chake, tiyenera kusankha pulasitiki ya aluminiyamu yokhala ndi kalasi yotsika moto pamsika, kuti kulimbana ndi moto kuli bwino, katundu wowotcha moto ndi wolimba, komanso magwiridwe antchito a okosijeni azinthu zofunikira ndizolimba, kupewa moto.
