Ingabe I-Led Ingcono Kunebhalbhu Lokukhanya?

Isingeniso:

Uma kukhulunywa ngokukhanyisa, isibani se-incandescent sendabuko sekuyisikhathi eside siyinketho kubantu abaningi. Kodwa-ke, eminyakeni yamuva nje, izibani ze-LED zithole ukuthandwa njengendlela eyonga amandla futhi ehlala isikhathi eside. Njengoba isidingo sezixazululo zokukhanyisa esimeme siqhubeka sikhula, abathengi abaningi bayazibuza: ingabe i-LED ingcono kunesibani sokukhanya? Kulesi sihloko, sizohlola umehluko phakathi kwezibani ze-LED namalambu okukhanya endabuko, sicabangela izici ezifana nokusebenza kahle kwamandla, ubude bokuphila, ikhwalithi yokukhanya, nomthelela wemvelo.

Okuyisisekelo Kwezibani ze-LED nama-Light Bulbs

I-LED, emele i-light-emitting diode, iwuhlobo lobuchwepheshe bokukhanyisa obusebenzisa i-semiconductor ukuze ikhiphe ukukhanya lapho amandla kagesi edlula kuwo. Uma kuqhathaniswa, izibani zokukhanya zendabuko ze-incandescent zikhiqiza ukukhanya ngokushisa ucingo lwe-filament kuze kube yilapho lukhanya. Lo mehluko obalulekile kubuchwepheshe usenhliziyweni yomehluko phakathi kwamalambu e-LED namalambu okukhanya.

Izibani ze-LED zaziwa ngokusebenza kahle kwamandla, zisebenzisa amandla amancane kakhulu ukukhiqiza inani lokukhanya elifana namalambu okukhanya endabuko. Ukwengeza, izibani ze-LED zinesikhathi eside kakhulu sokuphila, ngokuvamile zihlala amashumi ezinkulungwane zamahora uma kuqhathaniswa nempilo yamahora angu-1,000 yama-incandescent bulb. Ngakolunye uhlangothi, izibani ze-incandescent ziyaziwa ngokukhanya kwazo okufudumele, okujwayelekile okuvame ukukhethwa kuzilungiselelo ezithile.

Sinalezi zisekelo engqondweni, ake sijule ngezinzuzo ezithile kanye nobubi bezibani ze-LED namalambu okukhanya ukuze sinqume ukuthi yiliphi eliphuma phezulu.

Ukusebenza kahle kwamandla kanye nokonga izindleko

Omunye umehluko obaluleke kakhulu phakathi kwezibani ze-LED namalambu okukhanya endabuko amandla azo asebenza kahle. Izibani ze-LED ziwonga kakhulu amandla kunama-incandescent bulb, ngokuvamile asebenzisa amandla angaphansi ngo-75%. Lokhu kusho ukuthi amalambu e-LED angasiza abathengi bonge ezikweletini zabo zamandla kuyilapho benciphisa i-carbon footprint yabo.

Ngokungeziwe ekusebenziseni kwawo amandla aphansi, izibani ze-LED nazo ziphila isikhathi eside, okusho ukuthi zidinga ukushintshwa kancane kunama-incandescent bulb. Lokhu futhi kunomthelela ekongeni izindleko ngokuhamba kwesikhathi, njengoba abathengi bazosebenzisa imali encane ekuthengeni okunye nasekulungiseni.

Ngakolunye uhlangothi, izibani zendabuko ze-incandescent ziwonga kakhulu amandla, nengxenye ebalulekile yamandla awasebenzisayo eguqulwa abe ukushisa kunokukhanya. Lokhu akumoshi nje amandla kuphela kodwa futhi kunomthelela ezindlekweni zokupholisa eziphakeme ezindaweni ezingaphakathi endlini.

Sekukonke, uma kuziwa ekusebenzeni kahle kwamandla nokonga izindleko, izibani ze-LED zidlula ngokusobala amalambu avamile. Ukutshalwa kwezimali kokuqala kwezibani ze-LED kungase kube phezulu, kodwa ukonga kwesikhathi eside kanye nezinzuzo zemvelo kuwenza ukukhetha okubiza kakhulu.

Ubude bempilo kanye Nokuqina

Njengoba kushiwo ngaphambili, esinye sezici ezivelele zamalambu e-LED ubude bawo obukhethekile. Nakuba izibani ze-incandescent zendabuko ngokuvamile zihlala amahora angaba ngu-1,000, izibani ze-LED zinesilinganiso sokuphila samahora angu-25,000 kuya kwangu-50,000, okuwenza abe yinketho yokukhanyisa ehlala isikhathi eside.

Ukuphila isikhathi eside kwezibani ze-LED kubangelwa ukwakhiwa kwawo okuqinile, okuwenza amelane kakhulu nokushaqeka, ukudlidliza, namazinga okushisa adlulele uma kuqhathaniswa nezibani ze-incandescent ezintekenteke. Lokhu kwenza izibani ze-LED zifaneleke ikakhulukazi izinhlelo zokusebenza zangaphandle nezimboni lapho ukuqina kubalulekile.

Ngokuphambene, izibani ze-incandescent zintekenteke futhi zijwayele ukuphuka ngenxa yokwakheka kwazo okusekelwe emicu. Lokhu kunciphisa ukusebenza kwazo ezinhlelweni zangaphandle nasezindaweni ezinethonya eliphezulu, lapho izibani ze-LED zingaba ukukhetha okuthembeke kakhulu.

Uma kucatshangelwa ubude bawo bempilo ende nokuqina, izibani ze-LED yizona eziwina ngokusobala kulesi sigaba. Ukwakhiwa kwabo okuqinile kanye nokumelana nokugqoka nokuklebhula kubenza babe ukukhetha okuphakeme kwezinhlobonhlobo zezidingo zokukhanyisa.

Ikhwalithi Ekhanyayo Nezinketho Zombala

Esinye isici esibalulekile okufanele sicatshangelwe lapho uqhathanisa izibani ze-LED namalambu okukhanya endabuko yikhwalithi yokukhanya akukhiqizayo. Amalambu e-LED aziwa ngokuguquguquka kwawo ekukhiqizeni imibala ehlukahlukene nemibala yokukhanya, okuwenza afanelekele izinhlelo zokusebenza ezihlukene ezifana nokukhanyisa umsebenzi, ukukhanya kwe-ambient, nokukhanyisa kokuhlobisa. Lokhu kuvumelana nezimo kuvumela abathengi ukuthi bakhe imiklamo yokukhanyisa eyenziwe ngokwezifiso ukuze ivumelane nezintandokazi zabo nezidingo zabo.

Ukwengeza, amalambu e-LED ayakwazi ukukhiqiza ukukhanya kwekhwalithi ephezulu ngokunikeza umbala okungcono uma kuqhathaniswa nama-incandescent bulb. Ukunikezwa kombala kubhekisela ekhonweni lomthombo wokukhanya lokumela ngokunembile imibala yezinto, futhi izibani ze-LED zaziwa ngekhono lazo lokunikeza imibala ngokugqama kakhulu nangokwemvelo.

Ngakolunye uhlangothi, ama-incandescent bulbs anomkhawulo ekukhetheni kwawo umbala futhi ngokuvamile akhiqiza ukukhanya okufudumele, okuphuzi okuwuphawu lokukhanya kwekhaya kwendabuko. Nakuba abanye abantu bekhetha ukukhanya okufudumele kwama-incandescent bulbs kuzilungiselelo ezithile, ukungakwazi ukwenza ngokwezifiso umbala nekhwalithi yokukhanya kungaba yisiphazamiso ezinhlelweni eziningi.

Mayelana nekhwalithi yokukhanya nezinketho zombala, izibani ze-LED zinenzuzo ecacile ngaphezu kwamalambu okukhanya endabuko ngenxa yokuguquguquka kwawo, ukunikezwa kombala okuphakeme, kanye nezinketho zokukhanyisa okwenziwa ngokwezifiso.

Umthelela Wezemvelo Nokusimama

Njengoba umphakathi uqaphela kakhulu imvelo, umthelela wobuchwepheshe bokukhanyisa emhlabeni uwukucatshangelwa okubalulekile. Amalambu e-LED aqashelwa kabanzi njengenketho yokukhanyisa esimeme kakhudlwana uma kuqhathaniswa nezibani zendabuko ze-incandescent ngenxa yokusebenza kahle kwawo kwamandla, isikhathi eside sokuphila, kanye nomthelela omncane kwezemvelo.

Izibani ze-LED zisebenzisa amandla amancane, zinciphisa ukukhishwa kwekhabhoni kanye nesidingo sikagesi, okhiqizwa kakhulu emithonjeni engavuseleleki. Lokhu kunomthelela ekulandeleni okuncane kwemvelo futhi kusiza ukunciphisa imiphumela yemvelo yokusetshenziswa kwamandla.

Ngaphezu kwalokho, isikhathi eside sokuphila kwezibani ze-LED kusho ukuthi amayunithi ambalwa alahlwayo futhi agcina esendaweni yokulahla imfucumfucu, okunciphisa inani lemfucuza ye-elekthronikhi ekhiqizwayo. Izibani ze-LED nazo azinazo izinto eziyingozi njenge-mercury, ngokungafani nezinye izinhlobo zamalambu okukhanya endabuko, okuwenza aphephe emvelweni futhi alahleke kalula ekupheleni kwesikhathi sawo sokuphila.

Ngokuphambene, ama-incandescent bulb anomthelela omkhulu kwezemvelo ngenxa yokusebenzisa kwawo amandla aphezulu, isikhathi esifushane sokuphila, nezinto eziyingozi. Ngenxa yalokho, ukukhiqizwa nokulahlwa kwezibani ze-incandescent kunomthelela ekungcoleni, ekuncipheni kwezinsiza, kanye nokuqoqwa kwemfucuza.

Ngokombono wemvelo, amalambu e-LED ngokungangabazeki ayisinqumo esimeme kakhudlwana, esinikeza ukusebenza kahle kwamandla, ukukhiqizwa kwemfucuza okuncane, kanye nendawo encane yokulandela imvelo.

Isiphetho

Ekuphetheni, kusobala ukuthi izibani ze-LED ziyinketho yokukhanyisa ephakeme kakhulu uma kuqhathaniswa nezibani zendabuko ze-incandescent ezindaweni eziningana ezibalulekile. Izibani ze-LED ziwonga kakhulu amandla, zingabizi kakhulu, zihlala isikhathi eside, ziguquguquka, futhi azinzile, okuwenza abe ukukhetha okuhle kakhulu kwezidingo ezihlukahlukene zokukhanyisa ezindaweni zokuhlala, ezohwebo, nezimboni. Nakuba kungase kube nezimo ezithile lapho kukhethwa khona ukukhanya okufudumele, okujwayelekile kwama-incandescent bulb, izinzuzo eziningi zezibani ze-LED zizibeka njengesixazululo esingcono sokukhanyisa esikhathini esizayo.

Njengoba isidingo sokukhanya okuwonga ugesi nokunobungani kwemvelo siqhubeka sikhula, ubuchwepheshe be-LED sebulungele ukuba indinganiso yokukhanyisa izinhlelo zokusebenza emhlabeni wonke, bunikeze abathengi ikusasa eliqhakazile, elizinzile. Kungakhathaliseki ukuthi okwezindlu ezikhanyisayo, amabhizinisi, izindawo zomphakathi, noma izindawo ezingaphandle, izibani ze-LED zibonise ngokucacile ukuphakama kwazo ngaphezu kwamalambu okukhanya endabuko, zivulela indlela yomhlaba ogqamile futhi ozinzile.
