Ngaba iLed ingcono kuneBhalbhu yoKhanya?

Intshayelelo:

Xa kufikwa ekukhanyeni, iglobhu yesikhanyiso se-incandescent kudala iyindlela yokuya kubantu abaninzi. Nangona kunjalo, kwiminyaka yakutshanje, izibane ze-LED ziye zafumana ukuthandwa njengendlela eyonga amandla kunye nexesha elide. Njengoko imfuno yezisombululo zokukhanyisa ezizinzileyo ziqhubeka zikhula, abathengi abaninzi bayazibuza: ngaba i-LED ingcono kune-bulb yokukhanya? Kweli nqaku, siza kuphonononga umahluko phakathi kwezibane ze-LED kunye nezibane zemveli, sithathela ingqalelo izinto ezifana nokusebenza kwamandla, ixesha lokuphila, umgangatho wokukhanya, kunye nefuthe lokusingqongileyo.

Iziseko zeZibane ze-LED kunye neeBhalbhu zokukhanya

I-LED, emele i-diode ye-light-emitting diode, luhlobo lweteknoloji yokukhanyisa esebenzisa i-semiconductor ukuze ikhuphe ukukhanya xa umbane udlula kuyo. Xa kuthelekiswa, izibane zemveli ze-incandescent zivelisa ukukhanya ngokufudumeza ucingo lwefilament de lukhanyise. Lo mahluko usisiseko kwitekhnoloji isembindini wokungafani phakathi kwezibane ze-LED kunye neebhalbhu zokukhanya.

Izibane ze-LED zaziwa ngokusebenza kwazo kakuhle kwamandla, zisebenzisa amandla amancinci kakhulu ukuvelisa umlinganiselo ofanayo wokukhanya njengeebhalbhu zemveli. Ukongezelela, izibane ze-LED zinobomi obude kakhulu, zihlala zihlala amashumi amawaka eeyure xa kuthelekiswa nexesha le-1,000 leeyure zobomi be-incandescent bulbs. Ngakolunye uhlangothi, ii-bulb ze-incandescent ziyaziwa ngokufudumala kwazo, ukukhanya okuqhelekileyo okuhlala kukhethwa kwiindawo ezithile.

Ngale siseko engqondweni, masingene nzulu kwiingenelo ezithile kunye nezingeloncedo zezibane ze-LED kunye neeglowubhu zokukhanya ukufumanisa ukuba yeyiphi ephuma phezulu.

Ukusebenza kakuhle kwamandla kunye noLondolozo lweendleko

Owona mahluko ubalulekileyo phakathi kwezibane ze-LED kunye neebhalbhu zokukhanya zemveli kukusebenza kwazo ngamandla. Izibane ze-LED ziwonga kakhulu amandla kunee-incandescent bulbs, ngokuqhelekileyo zisebenzisa ama-75% amandla angaphantsi. Oku kuthetha ukuba izibane ze-LED zinokunceda abathengi bonge kwiibhili zabo zamandla ngelixa behlisa i-carbon footprint.

Ukongeza ekusebenziseni kwabo amandla aphantsi, izibane ze-LED zinexesha elide lokuphila, oku kuthetha ukuba kufuneka zitshintshwe ngokuphindaphindiweyo kunezibane ze-incandescent. Oku kukwanegalelo ekongiweni kweendleko ekuhambeni kwexesha, njengoko abathengi beya kuchitha imali encinane ekutshintsheni nasekulondolozeni.

Ngakolunye uhlangothi, ii-bulbs zendabuko ze-incandescent zinamandla angaphantsi kwamandla, kunye nenxalenye ebalulekileyo yamandla adlayo aguqulwa abe bubushushu kunokukhanya. Oku akuchithi nje amandla kuphela kodwa kunegalelo kwiindleko eziphezulu zokupholisa kwiindawo zangaphakathi.

Ngokubanzi, xa kufikwa ekusebenzeni kakuhle kwamandla kunye nokonga kweendleko, izibane ze-LED ngokucacileyo zigqwesa iibhalbhu zokukhanya eziqhelekileyo. Utyalo-mali lokuqala kwizibane ze-LED lunokuba luphezulu, kodwa ukugcinwa kwexesha elide kunye neenzuzo zokusingqongileyo kwenza ukuba kube yinto ebiza kakhulu.

Ubomi kunye nokuqina

Njengoko bekutshiwo ngaphambili, enye yeempawu ezibalaseleyo zezibane ze-LED bubomi bazo obukhethekileyo. Ngelixa iibhalbhu ze-incandescent zemveli zihlala malunga neeyure ezili-1,000, izibane ze-LED zine-avareji yobomi beeyure ezingama-25,000 ukuya kuma-50,000, nto leyo ezenza zibe lukhetho lokukhanyisa oluhlala ixesha elide.

Ubomi obude bezibane ze-LED kubalelwa kulwakhiwo lwazo oluqinileyo, olubenza baxhathise ukothuka, ukungcangcazela, kunye namaqondo obushushu agqithisileyo xa kuthelekiswa neebhalbhu ze-incandescent ezibuthathaka. Oku kwenza izibane ze-LED zifaneleke ngokukodwa kwizicelo zangaphandle kunye nezoshishino apho ukuqina kubalulekile.

Ngokwahlukileyo koko, iibhalbhu ze-incandescent zibuthathaka kwaye zivame ukuphuka ngenxa yoyilo olusekelwe kwi-filament. Oku kunciphisa ukusebenza kwabo kwiisethingi zangaphandle kunye neendawo ezinempembelelo ephezulu, apho izibane ze-LED ziya kuba lukhetho oluthembekileyo.

Ukuqwalasela ubomi babo obude kunye nokuqina, izibane ze-LED ziphumelele ngokucacileyo kolu didi. Ukwakhiwa kwabo okuqinileyo kunye nokuchasana nokugqoka kunye nokukrazula kubenza babe ukhetho oluphezulu kwiimfuno ezininzi zokukhanyisa.

Umgangatho wokukhanya kunye noKhetho loMbala

Enye into ebalulekileyo ekufuneka iqwalaselwe xa kuthelekiswa izibane ze-LED kunye nezibane zokukhanya zemveli ngumgangatho wokukhanya okuvelisayo. Izibane ze-LED ziyaziwa ngokuguquguquka kwazo ekuveliseni imibala eyahlukeneyo kunye nemibala yokukhanya, ezenza zifaneleke kwizicelo ezahlukeneyo ezifana nokukhanyisa umsebenzi, ukukhanya kwe-ambient, kunye nezibane zokuhombisa. Oku bhetyebhetye kuvumela abathengi ukuba benze uyilo lokukhanyisa olulungiselelweyo ukuze luhambelane nezinto abazithandayo kunye neemfuno.

Ukongeza, izibane ze-LED ziyakwazi ukuvelisa ukukhanya okukumgangatho ophezulu kunye nokunikezelwa kombala ongcono xa kuthelekiswa ne-incandescent bulbs. Unikezelo lombala lubhekisa kumandla omthombo wokukhanya ukumela ngokuchanekileyo imibala yezinto, kwaye izibane ze-LED zaziwa ngokukwazi kwazo ukunika imibala ngokucacileyo nangendalo.

Ngakolunye uhlangothi, iibhalbhu ze-incandescent zilinganiselwe kwiinketho zabo zemibala kwaye ngokuqhelekileyo zivelisa ukukhanya okufudumeleyo, okutyheli okuphawu lokukhanya kwekhaya. Ngelixa abanye abantu bekhetha ukukhanya okufudumeleyo kweebhalbhu ze-incandescent kwizicwangciso ezithile, ukungakwazi ukwenza umbala kunye nomgangatho wokukhanya kunokuba yintsilelo kwizicelo ezininzi.

Ngokumalunga nomgangatho wokukhanya kunye nokukhethwa kombala, izibane ze-LED zinenzuzo ecacileyo ngaphezu kweebhalbhu zokukhanya zendabuko ngenxa yokuguquguquka kwazo, ukunikezelwa kombala ophezulu, kunye neendlela zokukhanyisa ezizenzekelayo.

Impembelelo yokusingqongileyo kunye noZinzo

Njengoko uluntu luba nolwazi ngakumbi ngokusingqongileyo, impembelelo yobuchwepheshe bokukhanyisa kwiplanethi yinto ebalulekileyo yokuqwalaselwa. Izibane ze-LED zibonwa ngokubanzi njengendlela yokukhanyisa ezinzileyo ngakumbi xa kuthelekiswa ne-incandescent bulbs zendabuko ngenxa yokusebenza kakuhle kwamandla, ixesha elide lokuphila, kunye nefuthe elincinci lokusingqongileyo.

Izibane ze-LED zisebenzisa amandla amancinci, ukunciphisa ukukhutshwa kwekhabhoni kunye nemfuno yombane, eveliswa kakhulu kwimithombo engahlaziyiyo. Oku kunegalelo kunyawo oluncinci lwendalo kwaye kunceda ukunciphisa iziphumo zokusingqongileyo zokusetyenziswa kwamandla.

Ngaphaya koko, ubude bobomi bezibane ze-LED buthetha ukuba iiyunithi ezimbalwa zilahlwayo kwaye ziphelela kwiindawo zokulahla inkunkuma, ukunciphisa ubungakanani benkunkuma yombane eyenziweyo. Izibane ze-LED nazo azinazo izinto ezinobungozi ezifana ne-mercury, ngokungafaniyo nezinye iintlobo zeebhalbhu zokukhanya zendabuko, ezenza zikhuseleke ngokusingqongileyo kwaye zibe lula ukulahla ekupheleni kobomi babo.

Ngokwahlukileyo, iibulb ze-incandescent zinempembelelo enkulu yokusingqongileyo ngenxa yokusetyenziswa kwamandla aphezulu, ubomi obufutshane kunye nezinto ezinobungozi. Ngenxa yoko, ukuveliswa kunye nokulahlwa kwe-incandescent bulbs kunegalelo kungcoliseko, ukuchithwa kwezixhobo, kunye nokuqokelelwa kwenkunkuma.

Ngokwembono yokusingqongileyo, izibane ze-LED ngokungathandabuzekiyo lolona khetho luzinzileyo, olubonelela ngokusebenza ngokufanelekileyo kwamandla, ukuveliswa kwenkunkuma encinci, kunye nendawo encinci yendalo.

Ukuqukumbela

Ukuqukumbela, kuyacaca ukuba izibane ze-LED ziyindlela yokukhanyisa ephezulu xa kuthelekiswa nezibane eziqhelekileyo ze-incandescent kwiindawo ezininzi eziphambili. Izibane ze-LED zinamandla ngakumbi, zingabizi kakhulu, zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala, zorhwebo, kunye neshishini. Ngelixa kunokubakho iimeko ezithile apho ukufudumala okuqhelekileyo, ukukhanya okuqhelekileyo kwee-incandescent bulbs kukhethwa, izibonelelo ezininzi zezibane ze-LED zizibeka njengesisombululo esingcono sokukhanyisa kwixesha elizayo.

Njengoko imfuno yokukhanya okusebenza ngamandla kunye nokusingqongileyo iqhubeka ikhula, iteknoloji ye-LED ilungele ukuba ibe ngumgangatho wezicelo zokukhanyisa kwihlabathi jikelele, inika abathengi ikamva eliqaqambileyo, elizinzileyo. Nokuba yeyamakhaya akhanyisayo, amashishini, iindawo zikawonke-wonke, okanye iindawo ezingaphandle, izibane ze-LED zibonise ngokucacileyo ukongama kwazo kuneebhalbhu zokukhanya zesintu, zivula indlela yelizwe eliqaqambileyo nelizinzileyo.
