Nyali zopulumutsa mphamvu za LED ndizomwe zimagwiritsidwa ntchito pamakampani, ndipo pali zinthu zambiri zogawanika, monga nyali za mseu za LED, nyali zamtundu wa LED, nyali za LED zapamwamba, nyali za fulorosenti za LED ndi nyali zamagulu a LED.Pakali pano, msika waukulu wa nyali zopulumutsa mphamvu za LED zasintha pang'onopang'ono kuchokera kunja kupita ku mayiko, ndipo katundu kumisika yakunja ayenera kudutsa kuyendera, pamene zoweta za LED zopulumutsa mphamvu za nyali ndi zofunikira zokhazikika zikukhala zovuta kwambiri. kuyesa certification kwasanduka ntchito ya opanga nyali za LED.kuganizira.Ndiroleni ndikugawireni mfundo zazikulu 8 za miyezo yoyesera nyale zopulumutsa mphamvu za LED:
1. Zinthu
Nyali zopulumutsa mphamvu za LED zitha kupangidwa mosiyanasiyana monga mtundu wa chubu chozungulira.Tengani mowongoka chubu LED nyali fulorosenti monga chitsanzo.Maonekedwe ake ndi ofanana ndi chubu wamba fulorosenti.in. The mandala polima chipolopolo amapereka moto ndi magetsi kugwedezeka chitetezo mu mankhwala.Malinga ndi zomwe zimafunikira, zipolopolo za nyali zopulumutsa mphamvu ziyenera kufika pa V-1 kapena kupitilira apo, chifukwa chake chipolopolo cha polima chowonekera chiyenera kupangidwa ndi V-1 kapena kupitilira apo.Kuti mukwaniritse kalasi ya V-1, makulidwe a chipolopolocho ayenera kukhala akulu kuposa kapena ofanana ndi makulidwe ofunikira ndi kalasi ya V-1 yazinthu zopangira.Zofunikira pamoto ndi makulidwe amtunduwu zitha kupezeka pa UL chikasu pamakhadi azopangira.Pofuna kuonetsetsa kuwala kwa nyali zopulumutsa mphamvu za LED, opanga ambiri nthawi zambiri amapangitsa kuti chipolopolo cha polima chowonekera chikhale chochepa kwambiri, chomwe chimafuna kuti woyang'anira woyang'anira aziyang'anitsitsa kuti atsimikizire kuti zinthuzo zikugwirizana ndi makulidwe omwe amafunidwa ndi chiwerengero cha moto.
2. dontho mayeso
Malinga ndi zomwe zimafunikira mulingo wazogulitsa, chinthucho chimayenera kuyesedwa poyesa kutsika komwe kungachitike pakagwiritsidwe ntchito.Chogulitsacho chiyenera kugwetsedwa kuchokera kutalika kwa 0.91 mamita kufika pa bolodi lamatabwa, ndipo chipolopolocho sichiyenera kuthyoledwa kuti chiwonetsere mbali zoopsa zamoyo mkati.Pamene wopanga amasankha zinthu za chipolopolo cha mankhwala, ayenera kuchita mayesowa pasadakhale kuti apewe kuwonongeka komwe kumachitika chifukwa cha kulephera kwa kupanga kwakukulu.
3. Mphamvu ya dielectric
Chophimba chowonekera chimatsekera gawo la mphamvu mkati, ndipo zinthu zowonekera ziyenera kukwaniritsa zofunikira za mphamvu zamagetsi.Malinga ndi zomwe zimafunikira, kutengera mphamvu yaku North America ya volts 120, mbali zamkati zamkati zamphamvu kwambiri komanso chotchinga chakunja (chokutidwa ndi chitsulo chojambula kuti chiyesedwe) chiyenera kupirira mayeso amphamvu amagetsi a AC 1240 volts.Nthawi zonse, makulidwe a chipolopolo cha mankhwalawa amafika pafupifupi 0,8 mm, omwe amatha kukwaniritsa zofunikira za mayeso a mphamvu yamagetsi iyi.
4. gawo la mphamvu
Gawo lamagetsi ndi gawo lofunikira la nyali yopulumutsa mphamvu ya LED, ndipo gawo lamagetsi limagwiritsa ntchito ukadaulo wosinthira magetsi.Malingana ndi mitundu yosiyanasiyana ya ma modules amphamvu, miyeso yosiyana imatha kuganiziridwa poyesa ndi certification.Ngati gawo lamagetsi ndi gawo lachiwiri lamagetsi, izi zitha kuyesedwa ndikutsimikiziridwa ndi UL1310.Gulu lachiwiri lamagetsi limatanthawuza magetsi okhala ndi thiransifoma yodzipatula, voteji yotulutsa ndi yotsika kuposa DC 60V, ndipo yapano ndi yosakwana 150/Vmax ampere.Pamagetsi omwe si amtundu wa II, UL1012 imagwiritsidwa ntchito poyesa ndi kutsimikizira.Zofunikira zaukadaulo za miyezo iwiriyi ndizofanana kwambiri ndipo zitha kutumizidwa kwa wina ndi mnzake.Ma module ambiri amkati a nyali zopulumutsa mphamvu za LED amagwiritsa ntchito magetsi osadzipatula, ndipo ma voliyumu a DC amagetsi amaposa 60 volts.Chifukwa chake, mulingo wa UL1310 sukugwira ntchito, koma UL1012 ikugwira ntchito.
5. Zofunikira za insulation
Chifukwa cha malo ochepa amkati a nyali zopulumutsira mphamvu za LED, chidwi chiyenera kuperekedwa ku zofunikira zotetezera pakati pa mbali zowopsa zamoyo ndi zitsulo zopezeka pakupanga mapangidwe.Insulation ikhoza kukhala mtunda mtunda ndi creepage mtunda kapena insulating pepala.Malinga ndi zofunikira, mtunda wapakati pakati pa magawo owopsa amoyo ndi zitsulo zofikirika uyenera kufika 3.2 mm, ndipo mtunda wa creepage uyenera kufika 6.4 mm.Ngati mtunda suli wokwanira, pepala lotetezera likhoza kuwonjezeredwa ngati zowonjezera zowonjezera.makulidwe a pepala insulating ayenera kukhala wamkulu kuposa 0,71 mm.Ngati makulidwe ake ndi ochepera 0,71 mm, mankhwalawa amayenera kupirira mayeso a voteji a 5000V.
6. kuyesa kukwera kwa kutentha
Kuyesa kukwera kwa kutentha ndi chinthu choyenera kuchita poyesa chitetezo chazinthu.Muyezo uli ndi malire okwera kutentha kwa zigawo zosiyanasiyana.Mu gawo la kapangidwe kazinthu, wopanga ayenera kuyika kufunikira kwakukulu kwa kutentha kwa chinthucho, makamaka pazigawo zina (monga mapepala otsekereza, etc.) ayenera kusamala kwambiri.Magawo omwe amakumana ndi kutentha kwakukulu kwa nthawi yayitali amatha kusintha mawonekedwe awo, kupanga ngozi yamoto kapena kugwedezeka kwamagetsi.Mphamvu yamagetsi mkati mwa luminaire ili mu malo otsekedwa ndi opapatiza, ndipo kutentha kwa kutentha kumakhala kochepa.Choncho, pamene opanga amasankha zigawo zikuluzikulu, ayenera kusamala posankha zofunikira za zigawo zoyenera kuti atsimikizire kuti zigawozo zimagwira ntchito ndi malire ena, kuti asatengere kutentha kwakukulu chifukwa cha zigawo zomwe zimagwira ntchito pansi pa chikhalidwe chapafupi ndi katundu wambiri kwa nthawi yaitali. nthawi.
7. dongosolo
Pofuna kupulumutsa ndalama, ena opanga nyali za LED amagulitsa pamwamba pazigawo zamtundu wa pini pa PCB, zomwe sizili zofunika.Zigawo zamtundu wa pini zogulitsidwa pamtunda zitha kugwa chifukwa cha kusokeretsa ndi zifukwa zina, kubweretsa ngozi.Choncho, njira yowotcherera socket iyenera kutengedwa momwe zingathere pazigawozi.Ngati kuwotcherera pamwamba sikungalephereke, chigawocho chiyenera kuperekedwa ndi "L mapazi" ndikukhazikika ndi guluu kuti apereke chitetezo chowonjezera.
8. mayeso olephera
Kuyesa kulephera kwazinthu ndichinthu chofunikira kwambiri pakuyesa certification yazinthu.Chinthu choyeserachi ndikuzungulira pang'ono kapena kutsegula zigawo zina pamzere kuti zifananize zolephera zomwe zingachitike panthawi yomwe mukugwiritsa ntchito, kuti muwunikire chitetezo cha chinthucho pansi pa vuto limodzi.Kuti mukwaniritse zofunikira zachitetezo izi, popanga zinthuzo, ndikofunikira kuganizira kuwonjezera fusesi yoyenera kumapeto kwa chinthucho kuti tipewe kuchulukirachulukira kuti zisachitike mumikhalidwe yoopsa monga linanena bungwe laling'ono laling'ono komanso kulephera kwa gawo lamkati, zomwe zingayambitse. ku moto.
