Ii-LED ziyaziwa ngokusetyenziswa kwamandla aphantsi kunye nokukhanya okuphezulu.Ukukhanya kunye nokusetyenziswa kwamandla kungaphezulu kwe-60% eyahlukileyo kwiibhalbhu ze-tungsten eziqhelekileyo.Kodwa ayizizo zonke iiglowubhu ezicimayo, kwaye ixabiso leebhalbhu ezicimayo liya kuxabisa kakhulu, kuya kufuneka uvavanye iimfuno zakho ngaphambi kokuba ukhethe izibane zakho ze-LED.Oku kubaluleke ngakumbi xa utshintsha ukukhanya okudala kunye netekhnoloji entsha ye-LED okokuqala kwaye ulindele ukuba zifiphale.
Ngaba iibhalbhu zam ze-Edison zicima?
Ibhalbhu yesibane esiluzizi yibhalbhu yokukhanya ekwazi ukunyenyisa ukuqaqamba kokukhanya ngokweemfuno zomthengi, ngaloo ndlela ichaphazela ukuqaqamba kwesibane sangaphakathi kwaye ikhuphe imo engqongileyo eyahlukeneyo yangaphakathi.
Ukuba uthenge into egqityiweyo ye-LED okanye ibhalbhu, jonga ukuqinisekisa ukuba ukupakishwa kuchaza ngokuthe ngqo ukuba kuyacimeka.Oku kufuneka kuchazwe kwinkcazo okanye iinkcukacha zobugcisa bokukhanya.Ukuba usebenzisa i-LED engacimekiyo kwi-dimmer uya kufumana ukudada okuninzi kwaye uwonakalise ibhalbhu, unciphise ixesha lokuphila kwayo.Uphawu olufana nolungezantsi ngamanye amaxesha lusetyenziswa ukubonisa isibane siluzizi, ngelishwa akukho simboli ithile yendalo iphela.
Ngesiqhelo ukuba ibhalbhu yesibane inokufiphala ingabonwa kwipakethe yebhalbhu yesibane, kwaye iiglowubhu ezicimayo nazo zibiza kakhulu kuneebhalbhu zokukhanya ezingacimekiyo.Iibhalbhu zokukhanya ezicuthekileyo zinokuhlengahlengisa ukuqaqamba kokukhanya ngokweemfuno zabathengi, ngaloo ndlela zichaphazela ukuqaqamba kokukhanya kwangaphakathi kwaye zikhuphe imimoya engqongileyo eyahlukeneyo yangaphakathi, ukonga amandla kunye nokunciphisa ukukhutshwa kwekhabhoni.Abathengi abaninzi bathanda ukuthenga iiglowubhu ezicimayo.
Umgaqo wokufiphalisa ibhalbhu ye-Edison:
Njengomthombo oqhubekayo wangoku, ii-LED zibonakala zimfiliba ngokwendalo.Ukuqukuqela kwangoku kwintsimbi yesibane se-LED kumisela ukukhanya okuphumayo”.Ukukhanya kwabo kunokulungiswa ngokulula ngokulawula amandla akhoyo omgangatho wezinto ze-semiconductor ezifakwe kwi-substrate.Ii-LED azifani nemithombo yokukhanya yendabuko, kwaye ukufiphala akuchaphazeli ukusebenza kakuhle kunye nobomi be-LEDs.Ngapha koko, ubumnyama kunokunciphisa ubushushu babo bokusebenza, ngaloo ndlela kwandisa ubomi bee-LEDs.Nasiphi na isixhobo se-LED, ukuba siza kwenziwa kwindawo yokukhanya yokutshintsha okanye isibane se-LED, sidinga umqhubi ukuba afezekise ukufiphala.Ngenxa yokuba ii-LED ziyi-voltage ephantsi yomthombo we-DC, kwaye i-LED idinga umqhubi we-elektroniki ukuguqula i-AC ibe yi-DC esebenzisekayo kwaye iguqulelwe ngoku.
Kwimowudi yokumodareyitha kobubanzi be-pulse (PWM), yangoku nge-LED iyacinywa kwaye icinywe kwi-frequency ephezulu kakhulu, "ngokuqhelekileyo amawakawaka amaxesha ngomzuzwana", kwaye okwangoku nge-LED ilingana nexabiso eliphakathi langoku ngexesha. umjikelo wokutshintsha kwe-LED."Ngokunciphisa amandla-ngexesha le-LED, umyinge wangoku okanye osebenzayo ngoku ungancitshiswa, ngaloo ndlela unciphisa ukukhanya kwe-LED.Njengemithombo yokukhanya yendabuko, ii-LED zinokuthi zicuthe ngokucothayo ngokuqhubekayo (CCR), okanye ukuncipha kwe-analog.I-CCR igcina umthombo wokukhanya Kukho umsinga oqhubekayo, kodwa u-dimming ufezekiswa ngokunciphisa ubukhulu bangoku."Imveliso yokukhanya ilingana neyangoku ngesixhobo se-LED,"
Zombini i-PWM kunye ne-CCR zineenzuzo kunye nezingeloncedo.I-PWM isetyenziswa kakhulu kwaye inoluhlu olubanzi lobumnyama.Ngenxa yokuba ukufiphala kwe-PWM kusebenzisa ukucinywa nokucinywa ngokukhawuleza, kufuna izixhobo ezintsonkothileyo nezixabisa kakhulu zokuqhuba i-elektroniki ukuvelisa ii-pulses zangoku eziphezulu ngokwaneleyo ukukhusela amehlo abantu ekuzibhaqeni.eqhwanyaza.I-CCR dimming method iyasebenza kwaye ilula, kuba isixhobo sokuqhuba esiyifunayo silula kwaye singabizi.Ngokungafaniyo ne-PWM, i-CCR ayivelisi ukuphazamiseka kwe-electromagnetic EMI okubangelwa kukutshintsha kwamaza amaninzi.Nangona kunjalo, i-CCR ayizifanelanga izicelo apho imfuno yobumnyama ingaphantsi kwe-10%.“Kwimisinga ephantsi kakhulu, ii-LED azizange zisebenze kakuhle kwaye nokukhanya kwakungazinzanga.
Umbane olawulwayo wokulungisa umbane we-Silicon we-LED usetyenziselwe ukufiphalisa izibane ze-incandescent kunye nezibane zokonga umbane ngaphambili, kwaye ikwayeyona ndlela isetyenziswa kakhulu yobumnyama bokukhanya kwe-LED.Isilungisi esilawulwa yi-silicon luhlobo oluthile lobumnyama bomzimba.Umgaqo wayo wokusebenza kukuvelisa i-tangential output voltage waveform emva kokuba i-wave wave ye-voltage yegalelo isikiwe yi-angle yokuqhuba.Ukusebenzisa umgaqo we-tangential unokunciphisa ixabiso elisebenzayo lombane wokuphuma, ngaloo ndlela unciphisa amandla omthwalo oqhelekileyo (umthwalo ochasayo).I-Silicon elawulwa yi-rectifier dimmers inezibonelelo zokuchaneka okuphezulu kohlengahlengiso, ukusebenza kakuhle okuphezulu, ubungakanani obuncinci, ubunzima bokukhanya, kunye nolawulo olukude olulula.Ukukhanya okulungisiweyo kuthambile kwaye kuzinzile, kwaye akuyi kubakho i-stroboscopic phenomenon.lawula imarike.Izinto eziluncedo ze-Silicon controlled rectifier dimming zisebenza kakuhle kakhulu, ukusebenza okuzinzileyo kunye nexabiso eliphantsi lobumnyama.
Inqanaba elithathu lokuncipha kweemveliso zethu kwamkela unikezelo lwamandla ohlaziyiweyo olawulwa yisilicon.
Iimeko zokusetyenziswa kwebhalbhu yesibane ezicimayo:
Iibhalbhu zokukhanya ezicimayo zisetyenziswa kwiindawo ezahlukahlukeneyo, ezifana neehotele, iiholo zokudanisa, iindawo, iiholo zemiboniso kunye nezinye izihlandlo ezifuna ukukhanya, ngokuyintloko ngokuguqula isixa somthombo wokukhanya ukulungisa ukukhanya kokukhanya.Ngoku ngoku ukufudumala kwe-atmosphere, umba wendlela yokunciphisa ukusetyenziswa kombane ekukhanyiseni nawo usemnyango.Ngethamsanqa, ukuvela kwezibane ze-LED kugcina amandla amaninzi.Kuya kuba ngcono ngakumbi ukuba ummiselo unokusetyenziselwa ukonga amandla ngokufanelekileyo.Ukukhanya kweebhalbhu ze-LED, ezifana nezibane zodonga lwasekhaya, ii-ofisi, iindawo zokuthenga, izikolo, iifektri kunye nezinye izihlandlo zinokuhlengahlengiswa ngokwezibane ezifunekayo, kunye neziphumo zokonga amandla zinokufezekiswa.Ukuba ezi zihlandlo zitshintshwe ngeebhalbhu ze-LED ezihlengahlengiswayo, ziya kugcina amandla amaninzi.
Ukukhanya okucuthekileyo kukunika ukuguquguquka ukuze utshatise ukukhanya okujikelezileyo kumsebenzi wakho.Unokufuna ukukhanya okuqaqambileyo xa usebenza kwi-checkbook kodwa ukukhanya okuphumlayo okumfiliba xa usitya ngokuhlwa.Ukufiphaza kuye kwasetyenziswa ngakumbi ngaphakathi
iindawo zorhwebo nezoshishino.Ukongeza izibane eziluzizi kunika ukuguquguquka kwisithuba seofisi yakho kwaye kuvumela ukukhanya okugqibeleleyo kukhetho okanye iimfuno zabasebenzi bakho.Ingaba udibana neendwendwe, ubukele iTV, uphulaphule umculo, kunye nosapho lwakho, okanye ukucinga wedwa, unokuhlengahlengisa ukukhanya kwezibane ezahlukeneyo ukuze wenze umoya okhululekileyo, ozolileyo, ohambelanayo kunye nokufudumala, kunye namava anzulu obomi.Ukukhanya okuthambileyo kunokuzisa umoya olungileyo, ukukhanya okuncinci kunye nobumnyama kunokunceda ukucinga, ukukhanya okungaphezulu kunye nokukhanya okuqaqambileyo kunokwenza umoya ube shushu ngakumbi.Zonke iimfuno eziyinkimbinkimbi zinokufezekiswa ngokusebenza okulula, kwaye kufuneka kuphela ukulawulwa ngokutshintsha okuqhelekileyo ukulungisa ukukhanya kunye nobumnyama obukhanyayo beendawo ezahlukeneyo.
