Mumakore achangopfuura, nekukurumidza kufambira mberi kwe LED chip tekinoroji, kushandiswa kwekutengesa kwe LED kwave kwakakura kwazvo.Zvigadzirwa zve LED zvinozivikanwa se "green light sources" nekuda kwehukuru hwazvo hudiki, kuderera kwesimba rekushandisa, hupenyu hurefu hwebasa, kupenya kwakanyanya, kuchengetedza kwezvakatipoteredza, kusimba uye kusimba, pamwe neakakosha ekuchengetedza simba mwenje.Uchishandisa mwenje wemwenje we-ultra-bright uye wepamusoro-soro, ine magetsi emagetsi epamusoro, inogona kuchengetedza kupfuura 80% yemagetsi kupfuura mwenje wekare wekare, uye kupenya kunowedzera ka10 kwemarambi e-incandescent pasi pesimba rimwe chete.Hupenyu hurefu hunopfuura maawa 50 000, iyo inodarika ka50 yemarambi echinyakare tungsten filament.LED inotora yakavimbika yepamusoro yekurongedza tekinoroji-eutectic welding, iyo inovimbisa zvizere hupenyu hurefu hwe LED.Iyo inopenya yekuona kwekuita chiyero inogona kunge yakakwira se80lm/W kana kupfuura, akasiyana siyana emwenje yemwenje ye LED tembiricha iripo, yakakwira color rendering index, uye kunaka kwemavara kupa.LED mwenje tambo ye LED tekinoroji iri kufambira mberi nezuva rega rega, kugona kwayo kupenya kuri kuita zvinoshamisa, uye mutengo unogara uchidzikira.Sechigadzirwa chekuvhenekesa, chakapinda muzviuru zvedzimba nemigwagwa.
Nekudaro, zvigadzirwa zve LED mwenje sosi hazvisi pasina zvikanganiso.Kufanana nezvose zvigadzirwa zvemagetsi, marambi e LED anoburitsa kupisa panguva yekushandiswa, zvichikonzera kuwedzera kweambient tembiricha uye yavo tembiricha.LED inzvimbo yakasimba yechiedza ine diki-emitting chip nzvimbo uye yakakura ikozvino density kuburikidza chip panguva yekushanda;nepo simba reimwe LED chip idiki, uye inobuda inopenya flux zvakare yakaderera.Naizvozvo, kana ikashandiswa kumidziyo yekuvhenekesa, marambi mazhinji anoda Iko kusanganiswa kweakawanda ma LED emwenje masosi anoita iyo LED chip denser.Uye nekuti iyo photoelectric kutendeuka chiyero che LED mwenje sosi haina kukwirira, ingangoita 15% kusvika 35% yemagetsi simba inoshandurwa kuita chiedza kubuda, uye yakasara inoshandurwa kuita kupisa simba.Nokudaro, kana nhamba huru yezviedza zve LED zvichishanda pamwe chete, simba guru rekupisa richagadzirwa.Kana kupisa uku kusingakwanise kubviswa nekukurumidza sezvinobvira, zvinokonzeresa kuti tembiricha yekusangana kweiyo LED sosi yemwenje ikwire, kuderedza mafotoni anoburitswa nechip, kuderedza kupisa kwemavara emhando, kukurumidza kuchembera kwechip, uye kupfupisa hupenyu. yemudziyo.Naizvozvo, kuongororwa kwekupisa uye dhizaini yakakwana yechimiro chekupisa chekupisa chemarambi e LED inove yakakosha zvakanyanya.
Kubva pamakore eruzivo rwebudiriro yezvigadzirwa zve LED muindasitiri, yakanyatso dhizaini dhizaini sisitimu yakaumbwa.Semugadziri wechigadzirwa chekuvhenekesa, zvakaenzana nekumira pamapfudzi ehofori.Zvisinei, hakusi kuti zviri nyore kusvika pamusoro pamapfudzi ehofori.Kune matambudziko akawanda anoda kukundwa mukugadzirwa kwezuva nezuva.Semuenzaniso, kubva pakuona kwemutengo, mukugadzira, zvakakosha kusangana nezvinodiwa zvekupisa kupisa kwechigadzirwa, asiwo kuderedza mari;pari zvino, nzira inonyanya kushandiswa pamusika ndeye kushandisa aruminiyamu alloy fins yekupisa kupisa.Nenzira iyi, vagadziri vanoita sei Kuti vatarise kureba kwepakati pakati pefin nefin uye kureba kwechipedzi, pamwe nepesvedzero yechimiro chechigadzirwa pamhepo inoyerera uye kutaridzika kwenzvimbo inoburitsa chiedza, ichaita. kutungamirira mukusagadzikana kwekupisa kupisa.Aya ndiwo matambudziko anotambudza vagadziri.
Mukugadzirwa kwemarambi e LED, kune nzira dzakawanda dzekudzikisa tembiricha yekusangana kwe LED uye kuve nechokwadi chehupenyu hwe LED: ① Simbisa kupisa conduction (kune nzira nhatu dzekutamisa kupisa: kupisa conduction, convection heat exchange uye nemwaranzi heat exchange) , ②, sarudza Low thermal resistance LED chips, ③, pasi-kuremerwa kana kuremerwa shandisa simba rakatemerwa kana razvino re LED (zvinokurudzirwa kushandisa 70% ~ 80% yeiyo yakayerwa simba), inogona kunyatso kudzikisa iyo LED junction. tembiricha.
Zvadaro kusimbisa kupisa conduction, tinogona kutora nzira dzinotevera: ①, yakanaka yechipiri kupisa kupisa michina;②, kuderedza kupisa kwekushisa pakati pekuisa interface ye LED uye yechipiri kupisa kupisa nzira;③, wedzera kusangana pakati pe LED uye yechipiri kupisa kupisa meshini Iyo yekupisa conductivity yepasi;④, dhizaini yekugadzira uchishandisa musimboti wekutenderera kwemhepo.
Naizvozvo, kupisa kupisa igomba risingakundike kune vanogadzira zvigadzirwa muindasitiri yemwenje panguva ino.Panguva ino, ndinotenda kuti nekufambira mberi kwehunyanzvi hwekuvandudza tekinoroji, kukanganisa kwekupisa kwekupisa pama LEDs kuchaita kudiki zvishoma.Tiri kuedzawo kutsvaga nzira dzekudzikisa tembiricha yekusangana kwe LEDs, kuve nechokwadi chehupenyu hwe LED, uye kugadzira zvigadzirwa zvinodhura kuburikidza nekushandisa nzira..
