Izibane zokulondoloza amandla e-LED zigama eliqhelekileyo kwishishini, kwaye kukho iimveliso ezininzi ezicandekileyo, ezifana nezibane zesitrato ze-LED, izibane ze-tunnel ze-LED, izibane ze-LED eziphezulu, izibane ze-LED fluorescent kunye nezibane zepaneli ze-LED.Okwangoku, imarike ephambili ye-LED izibane zokugcina amandla ziye zatshintsha ngokuthe ngcembe ukusuka phesheya ukuya kwi-globalization, kunye nokuthumela ngaphandle kwiimarike zaphesheya kufuneka kudlule ukuhlolwa, ngelixa i-LED yasekhaya i-eneji yokugcina amandla izibane kunye neemfuno ezisemgangathweni ziya ziba ngqongqo ngakumbi, ngoko ke. uvavanyo lwesatifikethi lube ngumsebenzi wabavelisi bezibane ze-LED.ingqalelo.Mandabelane nawe ngamanqaku asi-8 aphambili emigangatho yovavanyo lwesibane sokugcina umbane we-LED:
1. Izinto eziphathekayo
Izibane zokonga umbane ze-LED zinokwenziwa zibe ziimilo ezahlukeneyo ezifana nodidi lwetyhubhu engqukuva.Thatha ityhubhu ethe ngqo ye-LED yesibane se-fluorescent njengomzekelo.Ubume bayo bufana netyhubhu eqhelekileyo ye-fluorescent.in. Iqokobhe lepolymer ecacileyo libonelela ngokhuseleko lomlilo kunye nombane kwimveliso.Ngokweemfuno eziqhelekileyo, izinto zegobolondo zezibane zokugcina amandla kufuneka zifikelele kwinqanaba le-V-1 okanye ngaphezulu, ngoko igobolondo ye-polymer ebonakalayo kufuneka yenziwe kwinqanaba le-V-1 okanye ngaphezulu.Ukufezekisa ibakala le-V-1, ubukhulu beqokobhe lemveliso kufuneka bube bukhulu okanye bulingane nobukhulu obufunwa ngumgangatho we-V-1 wezinto eziluhlaza.Ukukala komlilo kunye neemfuno zokutyeba zinokufunyanwa kwikhadi elityheli le-UL lemathiriyeli ekrwada.Ukuze kuqinisekiswe ukukhanya kwezibane zokulondoloza amandla e-LED, abaninzi abavelisi bahlala besenza iqokobhe le-polymer ecacileyo lincinci kakhulu, elifuna ukuba injineli yokuhlola inikele ingqalelo ekuqinisekiseni ukuba izinto zidibana nobukhulu obufunwa ngumlinganiselo womlilo.
2. uvavanyo lwehla
Ngokweemfuno zomgangatho wemveliso, imveliso kufuneka ivavanywe ngokufanisa imeko yokuhla enokuthi yenzeke kwinkqubo yokusetyenziswa kwangempela.Imveliso kufuneka iwiswe ukusuka kubude be-0.91 yeemitha ukuya kwibhodi yomthi oqinileyo, kwaye igobolondo lemveliso akufanele liphulwe ukuveza iindawo ezinobungozi ngaphakathi.Xa umenzi ekhetha izinto zeqokobhe lemveliso, kufuneka enze olu vavanyo kwangaphambili ukuze aphephe ilahleko ebangelwa kukungaphumeleli kokuveliswa kobuninzi.
3. Amandla e-Dielectric
I-casing ecacileyo ifaka imodyuli yamandla ngaphakathi, kwaye i-casing material ecacileyo kufuneka ihlangabezane neemfuno zamandla ombane.Ngokweemfuno eziqhelekileyo, ngokusekelwe kumbane we-North America we-voltage ye-120, iindawo eziphilayo zangaphakathi eziphezulu ze-voltage kunye ne-casing yangaphandle (egqunywe nge-foil yensimbi yokuvavanya) kufuneka ikwazi ukumelana novavanyo lwamandla ombane we-AC 1240 volts.Kwiimeko eziqhelekileyo, ubukhulu begobolondo lemveliso bufikelela malunga ne-0.8 mm, enokuthi ihlangabezane neemfuno zolu vavanyo lwamandla ombane.
4. imodyuli yamandla
Imodyuli yamandla yinxalenye ebalulekileyo yesibane sokugcina amandla e-LED, kwaye imodyuli yamandla ithatha ngokuyinhloko iteknoloji yokubonelela ngombane.Ngokweentlobo ezahlukeneyo zeemodyuli zamandla, imigangatho eyahlukeneyo inokuqwalaselwa ukuvavanya kunye nokuqinisekiswa.Ukuba imodyuli yamandla yiklasi ye-II yonikezelo lwamandla, oku kunokuvavanywa kwaye kuqinisekiswe nge-UL1310.Unikezelo lwamandla lweClass II lubhekiselele kunikezelo lwamandla kunye ne-transformer yodwa, amandla ombane aphumayo angaphantsi kwe-DC 60V, kwaye okwangoku ingaphantsi kwe-150/Vmax ampere.Ukubonelela ngombane ongeyonxalenye yeklasi ye-II, i-UL1012 isetyenziselwa ukuvavanya kunye nokuqinisekiswa.Iimfuno zobugcisa zale migangatho mibini zifana kakhulu kwaye zinokuthunyelwa omnye komnye.Uninzi lweemodyuli zangaphakathi zamandla ezibane zokonga umbane ze-LED zisebenzisa izixhobo zamandla ezingezizo zodwa, kwaye umbane we-DC ophumayo wonikezelo lwamandla nawo ungaphezulu kwe-60 volts.Ke ngoko, umgangatho we-UL1310 awusebenzi, kodwa i-UL1012 iyasebenza.
5. Iimfuno ze-insulation
Ngenxa yesithuba esilinganiselweyo sangaphakathi sezibane zokulondoloza amandla e-LED, ingqwalasela kufuneka ihlawulwe kwiimfuno ze-insulation phakathi kweendawo eziphilayo ezinobungozi kunye neengxenye zetsimbi ezifikelelekayo ngexesha loyilo lwesakhiwo.I-Insulation ingaba ngumgama wendawo kunye nomgama we-creepage okanye i-insulating sheet.Ngokweemfuno eziqhelekileyo, umgama wendawo phakathi kweendawo eziphilayo ezinobungozi kunye neentsimbi ezifikelelekayo kufuneka zifikelele kwi-3.2 mm, kwaye umgama we-creepage kufuneka ufikelele kwi-6.4 mm.Ukuba umgama awaneleyo, ishidi lokukhusela lingafakwa njenge-insulation eyongezelelweyo.Ubunzima bephepha le-insulating kufuneka libe likhulu kune-0.71 mm.Ukuba ubukhulu bungaphantsi kwe-0.71 mm, imveliso kufuneka ikwazi ukumelana novavanyo oluphezulu lwe-voltage ye-5000V.
6. uvavanyo lokunyuka kobushushu
Uvavanyo lokunyuka kobushushu yinto ekufuneka yenziwe kuvavanyo lokhuseleko lwemveliso.Umgangatho unemida ethile yokunyuka kweqondo lokushisa kumacandelo ahlukeneyo.Kwinqanaba loyilo lwemveliso, umenzi kufuneka afake ukubaluleka okukhulu ekutshitshisweni kokushisa kwemveliso, ngokukodwa kwiindawo ezithile (njengama-insulating sheets, njl. njl.) kufuneka ahlawule ngokukodwa.Amalungu avuleleke kumaqondo obushushu anyukileyo ixesha elide anokutshintsha iimpawu zawo zomzimba, enze ingozi yomlilo okanye yombane.Imodyuli yamandla ngaphakathi kwe-luminaire ikwindawo evaliweyo kunye nencinci, kwaye ukutshatyalaliswa kobushushu kuncinci.Ngoko ke, xa abavelisi bekhetha amacandelo, kufuneka banikele ingqalelo ekukhetheni ukucaciswa kwamacandelo afanelekileyo ukuqinisekisa ukuba amacandelo asebenza ngomda othile, ukwenzela ukuba kuthintelwe ukutshisa okubangelwa ngamacandelo asebenza phantsi kwemeko yokuvala umthwalo opheleleyo ixesha elide. ixesha.
7. isakhiwo
Ukuze kugcinwe iindleko, abanye abavelisi bezibane ze-LED bathengisa umphezulu we-pin-type components kwi-PCB, engathandekiyo.Amalungu odidi lwe-pin-soldered anokuthi awele ngenxa yesongiso yenyani kunye nezinye izizathu, ezibanga ingozi.Ke ngoko, indlela ye-socket welding kufuneka yamkelwe ngokusemandleni kula macandelo.Ukuba i-welding surface ayinakuphepheka, icandelo kufuneka linikezwe "ienyawo ze-L" kwaye lilungiswe ngeglue ukunika ukhuseleko olongezelelweyo.
8. uvavanyo lokungaphumeleli
Uvavanyo lokungaphumeleli kwemveliso yinto yovavanyo oluyimfuneko kakhulu kuvavanyo lwesiqinisekiso semveliso.Le nto yovavanyo kukujikeleza okufutshane okanye ukuvula amanye amacandelo emgceni ukulinganisa ukusilela okunokwenzeka ngexesha lokusetyenziswa kwangempela, ukuze kuvavanywe ukhuseleko lwemveliso phantsi kweemeko ezinempazamo enye.Ukuze kuhlangatyezwane nale mfuneko yokhuseleko, xa kuyilwa imveliso, kuyimfuneko ukuqwalasela ukongeza i-fuse efanelekileyo ekupheleni kwegalelo lemveliso ukuthintela ukugqithiswa kwe-overcurrent ukuba kwenzeke kwiimeko ezinzima ezifana nemveliso yesiphaluka esifutshane kunye nokungaphumeleli kwecandelo langaphakathi, elinokuthi likhokhelele. ukutshisa.
