Sei kuderera kwechiedza kuchiitika uye maitiro ekugadzirisa nayo
Zviedza zvakafanana nevanhu, uye nekufamba kwenguva, nzira dzakasiyana-siyana dzekushanda dzinoramba dzichiderera, uye pakupedzisira kusvikira kuderera. Hazvina mhosva kuti rudzi rwechiedza chechiedza chisingagoni kudzivisa, uye ichi ndicho chiedzadepreciationchechiedza.
Zvikonzero zvekuderera kwechiedza
Pachine makakatanwa akawanda pamusoro pechikonzero chekuora kwechiedza, uye nzira ye microscopic inokonzera kuderera haisati yanyatsojeka. Zvisinei, kazhinji, kuora kwechiedza kwe LED kunonyanya kukonzerwa nekupisa kupisa.
LED inotya kupisa chinhu chinozivikanwa, LED yakanaka yekushanda tembiricha iri pakati -5 ~ 0 °, asi izvi hazvigoneke, kupisa kuchakanganisa kuora kwechiedza uye hupenyu hwemarambi e LED, LED ichashanda Inenge 80% ye simba remagetsi rinoshandurwa kuita simba rekupisa, uye 20% yesimba remagetsi rinoshandurwa kuva simba rechiedza. Iyo LED radiator inoshandiswa kubvisa kupisa kwe LED. Nekuti iyo LED chip iri kushanda, yake ambient tembiricha inopindirana nechiyero chekubuda kwechiedza. Iyo yakakwirira tembiricha, inodzikira chiyero chekubuda kwechiedza. Kana tembiricha ichisvika pakupisa kwakanyanya kweiyo LED chip, mwenje unopwanya.
Pamusoro pezvo, kupisa kwekupisa kweiyo LED chip pachayo, pesvedzero yesirivheri paste, kupisa kwekupisa kweiyo substrate, uye colloid negoridhe waya zvine hukamawo nekuora kwechiedza.
Nzira yekugadzirisa sei kuora kwechiedza chemarambi?
Muchokwadi, mupfungwa yakasimba, mwenje we LED haugone kudzivirira kuora kwechiedza. Iri idambudziko rehunyanzvi iro indasitiri inotarisira nekukurumidza, asi chero bedzi isu tichinzwisisa nzira yekupisa yekupisa yemarambi, tinogona kuderedza dambudziko rekudzikisa chiedza kusvika pamwero.
Chinhu chekutanga kunzwisisa ndeye tembiricha yejunction?
Iyo tembiricha yekusangana ndiyo tembiricha yekushanda yePN junction ye semiconductor chip (wafer, die). Iyo yakakwirira tembiricha yejunction, ndiko kutanga kwekuora kwechiedza kunoitika. Kana tembiricha yejunction iri 105 madhigirii, hupenyu hwekupenya kuderera kusvika 70% ingori maawa gumi, pane maawa makumi maviri nemazana mapfumbamwe nemashanu, uye tembiricha yejunction yakaderedzwa kusvika 75 degrees, hupenyu hunotarisirwa maawa makumi mashanu, uye tembiricha inogona. kuwedzerwa kusvika ku65 degrees, 90,000 maawa. Naizvozvo, kiyi yekuwedzera hupenyu kudzikisa tembiricha yejunction. Kiyi yekudzikisa tembiricha yejunction kuve nekudziya kwakanaka kwekunyura. Saka iwe unoona sei zvakarongeka kupisa kwekupisa kwemarambi e LED?
Kazhinji, tembiricha yekusangana kweiyo LED inokwira uye inopenya flux inoderera. Zvadaro, chero bedzi isu tichiyera kuchinja kwechiedza chechiedza munzvimbo imwe chete, tinogona kushandura kuchinja kwekushisa kwejunction. Iyo chaiyo nzira ndeye:
1. Sarudza nzvimbo isiri pasi pekukanganiswa kwechiedza chekunze, kunyanya usiku, dzima mamwe magetsi;
2, batidza mwenje munzvimbo inotonhora, kurumidza kuyera kupenya kwenzvimbo, rekodha kuverenga panguva ino se "kuvhenekera kunotonhora";
3. Chengetedza nzvimbo ye luminaire uye illuminometer isina kuchinjwa, uye zviedza zvinoramba zvichishanda;
4. Mushure mehafu yeawa, verenga kukosha kwekuvhenekera pano uye nyora kuverenga se "chiedza chinopisa";
5. Kana iyo miviri miviri yakafanana (10 ~ 15%), hurongwa hwekupisa kwemwenje hunonyanya kunaka;
6. Kana iyo miviri miviri iri kure (yakakura kupfuura 20%), hurongwa hwekupisa kwemwenje hunopokana.
Uye zvakare, isu hatigone kungotarisa mutengo wekuona kunaka kweiyo radiator, isu tinofanirwa kusarudza iyo inodhura-inoshanda.
1, ruoko runobata radiator runopisa zvakanyanya, chokwadi haruna kunaka, ruoko runobata radiator haruna kupisa harina kunaka;
2, muchiitiko chekugadzirwa kunonzwisisika, huremu hwakafanana, nzvimbo yepamusoro, kupisa kupisa kwakanaka;
3, zvinhu zvakafanana, nzvimbo yakafanana, iyo inorema uremu, kupisa kwakanaka.
4. Mhedzisiro yefin heat sink haisi yakanaka sezvinobvira. Iyo denser iri nani.
Kuora kwechiedza idambudziko risingadzivisiki mubasa remarambi. Paunenge uchitenga marambi, unofanirwa kusarudza marambi ane hutano huri nani uye kupisa kupisa, kuderedza basa.
