Mavuto Amene Amapezeka Nthawi zambiri mu Mikanda ya Nyali ya Infrared LED Amathetsedwa

1) Onani ngati magetsi amagetsi akugwira ntchito bwino, komanso ngati magetsi owonetsera akuyaka. Ngati sichiyatsidwa, chonde onani ngati magetsi alumikizidwa; , Kodi pali zosiyana, ngati pali mafunso pamwamba, chonde athe kulumikiza molondola. Mikanda ya nyali ya LED yotchedwa 3V, kwenikweni, mitundu yosiyanasiyana imakhalanso ndi zopempha zosiyanasiyana zamakono. ** Pempho lamakono ndilochepa kwambiri, lomwe ndi lofiira, lobiriwira, loyera ndi labuluu. Ngati madziwa ndi aakulu kwambiri, pachimake chidzawotchedwa. Gwiritsani ntchito batri yowonjezereka ya 2.4V, ** ndiyosavuta kuyaka, chifukwa ngakhale magetsi si aakulu, mphamvuyi ndi yaikulu kwambiri, idzawotchedwabe pakufuna kwake. Pa nthawi yogwiritsira ntchito mabatani, chifukwa mphamvu ya mabatani ndi 3V, chifukwa mphamvu yotulutsa mabatani ndi yaying'ono, nyali ya 3V LED sidzawotchedwa. Chifukwa chake, mukamagwiritsa ntchito mikanda ya nyali ya LED, muyenera kusankha magetsi oyenera, samalani ndi voliyumu, komanso magetsi. Mphamvu yamagetsi ikasankhidwa, ngati zopempha zowonjezera za mkanda wa nyali ya LED sizikukwanira, kufunikira kumawongolera dera. Pansi pa kukana kopanda tanthauzo, ngati kuli koyenera kusankha pakugula, kumalimbikitsa batire ya 3V. Posankha, gwiritsani ntchito batri kuti muwone mosavuta zomwe LED imatumizidwa. 1) Zingwe ziwiri mmwamba ndi pansi. Makampani athu amatchedwa golide wagolide, golide woyenga, ndipo amagwiritsidwa ntchito ngati magetsi oyendetsa, mizati iwiri yabwino, mizati iwiri yolakwika. Chitetezo cha 2) Filament yochepa tsopano yakuuzani momveka bwino kuti kuwala kwanu kwatenthedwa ndi mphamvu yaikulu, yomwe ikufanana ndi kusokoneza 3) Kuyendetsa panopa ndi mphamvu yaikulu ya 1W ndi 350mA, ndipo mphamvu yogwiritsira ntchito ndi 3.2- 3.2- Pakati pa 3.6V, chonde tcherani khutu mukamagwiritsa ntchito, mafunde aakulu kwambiri adzawotcha magetsi 4) Kawirikawiri mbale zitatu za 1W aluminium-based aluminium zimayendetsedwa ndi 12V. Kodi pali gwero losowa lomwe ndi locheperapo mphamvu yoyendetsa ya 12V? mphira wosindikizira wakunja wa LED wachikasu chinthu eyiti amapangidwa ndi kusafananiza kwa epoxy esters ndi machiritso Kwanthawi yayitali. Yankho: Gulani mu chosindikizira chakunja ndikuchiritsa, monga guluu wamtundu wa 800 kapena 2339 wa Shanghai Fine Chemical Everbichels, womwe sudzawonetsa zotsatirazi. Komanso tcherani khutu kupanga ndi kuwongolera, kutsatira mosamalitsa magwiridwe antchito , Izi zimayendetsedwa bwino kwambiri. Zida sizimakhazikika, ndipo ogwira ntchito samavala chibangili chokhazikika (ayenera kukhala ndi chingwe). Electrostatic chitetezo chopangidwa sichoyenera. Ndiye, pa phukusi, kuwotcherera mzere PAD kuwotcherera pamapeto pake amafunsidwa. Onse awiri sanali. Mikanda ya nyali ya LED inali chubu chachiwiri. Pamafunika mphamvu yabwino yosinthira kuti igwire ntchito, nthawi zambiri 2-3.5V. Ndiko kunena kuti, mikanda ya nyali ya LED imangosintha mphamvu yamagetsi kukhala mphamvu yowunikira. Pali zinthu zinayi zomwe zimapangitsa kuti ma LED ang'onoang'ono achepetse mphamvu: 1: Kusayendetsa bwino kwa kutentha kwa zotchinga zachitsulo. Awiri: epoxy resin yellowization. Chachitatu: tchipisi ndi mabulaketi sizimakhudzidwa mwamphamvu. Chachinayi: Chip ndi kuchepetsa. Ngati ndi kuwala koyera, palinso funso la fulorosenti ufa attenuation.
