Uhlalutyo lwesicelo sokukhanyisa i-LED kwindawo ebandayo
Emva kweminyaka eyi-10 yophuhliso olukhawulezayo, ukukhanya kwe-LED kungene kwinqanaba lokunyusa ngokukhawuleza, kwaye isicelo semarike siye sanda ngokuthe ngcembe ukusuka kummandla wokuqala osezantsi ukuya kwimimandla ephakathi nasentshona. Nangona kunjalo, kwisicelo sokwenyani, sifumene ukuba iimveliso zokukhanyisa zangaphandle ezisetyenziswa emazantsi zivavanywa kakuhle kwimimandla esemantla, ngakumbi kumntla-mpuma. Eli nqaku lihlalutya ezinye zezinto eziphambili ezichaphazela ukukhanya kwe-LED kwiindawo ezibandayo, zifumanisa izisombululo ezihambelanayo, kwaye ekugqibeleni zikhupha iingenelo zemithombo yokukhanya kwe-LED.
Okokuqala, iingenelo zokukhanyisa kwe-LED kwiindawo ezibandayo
Xa kuthelekiswa nesibane sokuqala se-incandescent, isibane se-fluorescent kunye nesibane sokukhupha igesi ephezulu, ukusebenza kwesixhobo se-LED kungcono kakhulu kubushushu obuphantsi, kwaye kunokuthiwa ukuba ukusebenza kwamehlo kugqwesileyo kunobushushu obuqhelekileyo. Oku kuhambelana ngokusondeleyo neempawu zobushushu zesixhobo se-LED. Njengoko ubushushu be-junction buyancipha, ukukhanya okukhanyayo kwesibane kuya kunyuka ngokulinganayo. Ngokomthetho wokutshatyalaliswa kobushushu besibane, iqondo lokushisa le-junction lihambelana ngokusondeleyo nobushushu be-ambient. Okuya kusezantsi ubushushu be-ambient, kokukhona ubushushu besiphambuka buphantsi. Ukongeza, ukuthoba ubushushu besiphambuka kunokunciphisa inkqubo yokubola kokukhanya komthombo wokukhanya kwe-LED kunye nokulibazisa ubomi benkonzo yesibane, ekwaluphawu lwamacandelo amaninzi e-elektroniki.
Ubunzima kunye nokuBambisana nokuKhanya kwe-LED kwindawo ebandayo
Nangona i-LED ngokwayo ineenzuzo ezininzi kwiimeko ezibandayo, ayinakungahoywa ukuba ngaphezu kwemithombo yokukhanya. Izibane ze-LED zikwanxulumene ngokusondeleyo namandla okuqhuba, izixhobo zomzimba wesibane, kunye nemozulu enenkungu, i-ultraviolet eyomeleleyo kunye nezinye imozulu ebanzi kwiindawo ezibandayo. Izinto ziye zazisa imingeni emitsha kunye neengxaki ekusetyenzisweni kwalo mthombo wokukhanya omtsha. Kuphela ngokucacisa le miqobo kunye nokufumana izisombululo ezihambelanayo, sinokunika umdlalo opheleleyo kwiinzuzo zemithombo yokukhanya ye-LED kunye nokukhanya kwindawo ebandayo.
1. Ingxaki yokuqalisa iqondo lobushushu eliphantsi lonikezelo lwamandla okuqhuba
Wonke umntu owenza uphuhliso lonikezelo lwamandla uyazi ukuba ubushushu obuphantsi ukuqala kobonelelo lwamandla kuyingxaki. Isizathu esona sizathu kukuba uninzi lwezisombululo zamandla asele zikhulile azinakwahlulwa kwisicelo esibanzi se-electrolytic capacitors. Nangona kunjalo, kwindawo yokushisa ephantsi kwe-25 ° C, umsebenzi we-electrolytic we-electrolytic capacitor uyancipha kakhulu, kwaye umthamo we-capacitance uyancipha kakhulu, obangela ukuba isiphaluka singasebenzi kakuhle. Ukuyicombulula le ngxaki, okwangoku kukho izisombululo ezimbini: enye kukusebenzisa i-capacitors ekumgangatho ophezulu kunye noluhlu olubanzi lweqondo lokushisa lokusebenza, ngokuqinisekileyo luya kwandisa iindleko. Okwesibini kuyilo lwesekethe usebenzisa i-electrolytic capacitors, kubandakanywa i-ceramic laminated capacitors, kunye nezinye izikimu zokuqhuba ezifana ne-linear drive.
Ukongeza, phantsi kwemeko yobushushu obuphantsi, ukusebenza kwamandla ombane wezixhobo zombane eziqhelekileyo kuya kuncipha, okuya kuchaphazela kakubi ukuthembeka okupheleleyo kwesekethe, efuna ingqalelo ekhethekileyo.
2. Ukuthembeka kwezixhobo zeplastiki phantsi kwefuthe eliphezulu kunye neqondo lokushisa eliphantsi
Ngokutsho imifuniselo eyenziwa ngabaphandi kumaziko athile ophando ekhaya nakwamanye amazwe, ezininzi zeplastiki eziqhelekileyo kunye nerubber izinto irabha ukuba ukuqina amahlwempu kunye nokunyuka brittleness kumaqondo obushushu aphantsi ngaphantsi -15 ° C. Kwiimveliso zangaphandle LED, izinto transparent, iilensi optical, amatywina kunye nabanye. iindawo zokwakha zingasebenzisa izinto zeplastiki, ngoko ke iipropati eziphantsi zobushushu obuphantsi kwezi zixhobo kufuneka ziqwalaselwe ngononophelo, ngokukodwa izixhobo ezithwala umthwalo, ukuphepha izibane phantsi kwendawo yokushisa ephantsi, iya kugqabhuka emva kokubethwa ngumoya onamandla kwaye ukungqubana ngengozi.
Ukongeza, izibane ze-LED zihlala zisebenzisa indibaniselwano yeengxenye zeplastiki kunye nesinyithi. Ngenxa yokuba i-coefficients yokwandiswa kwezinto zeplastiki kunye nezixhobo zetsimbi zihluke kakhulu phantsi kokwahlukana okukhulu kweqondo lokushisa, umzekelo, i-coefficients yokwandisa i-aluminium yensimbi kunye nezixhobo zeplastiki eziqhelekileyo ezisetyenziselwa izibane malunga namaxesha angama-5 ahlukeneyo, anokubangela ukuba izinto zeplastiki ziqhekeke okanye i-gap. phakathi kwezi zimbini. Ukuba inyuswa, isakhiwo sokutywinwa esingenamanzi siya kuthi ekugqibeleni singasebenzi, okuya kubangela iingxaki zemveliso.
Kummandla weentaba, ukususela ngo-Oktobha ukusa kuAprili wonyaka olandelayo, kusenokubakho ixesha lekhephu nomkhenkce. Ubushushu besibane se-LED bunokuba ngaphantsi kune -20 ℃ ngokuhlwa ngaphambi kokuba isibane sikhanyise ngokuhlwa, kwaye emva kokuba umbane uvuliwe ebusuku, ubushushu bomzimba wesibane bunganyuka ukuya kuma-30 ℃ ～ 40. ℃ ngenxa yokufudumeza kwesibane. Fumana umothuko womjikelo ophezulu kunye nophantsi wobushushu. Kulo mmandla, ukuba i-structural design ye-luminaire kunye nengxaki yokudibanisa izinto ezahlukeneyo aziphathwa kakuhle, kulula ukubangela iingxaki zokuqhekeka kwezinto kunye nokungaphumeleli kwamanzi okukhankanywe ngasentla.
