Izibani ze-LED, noma i-Light-Emitting-Diodes, ubuchwepheshe obusha.UMnyango Wezamandla wase-United Statesibala ama-LED “njengobunye bobuchwepheshe bokukhanyisa banamuhla obuwonga kakhulu futhi obuthuthuka ngokushesha.” Ama-LED asephenduke isikhanyisi esisha esiyintandokazi samakhaya, amaholide, amabhizinisi, nokuningi.

Izibani ze-LED zinezinzuzo eziningi kanye nezinkinga ezimbalwa. Ucwaningo lubonisa ukuthi izibani ze-LED ziwonga amandla, zihlala isikhathi eside, futhi ziyikhwalithi enhle. Ezingeni lomthengi nebhizinisi, ukushintshela kuma-LED konga imali namandla.

Sihlanganise izinzuzo eziphezulu kanye nokubi kwezibani ze-LED. Qhubeka ufunda ukuze ufunde ukuthi kungani kuwumbono okhanyayo ukushintshela kumalambu e-LED.

Izinzuzo zezibani ze-LED

Izibani ze-LED zisebenza kahle kakhulu

Ukukhanyisa kwe-LED kudume ngokonga amandla kakhulu kunangaphambili. Ukuze banqume ukusebenza kahle kwamandla amalambu okukhanya, ochwepheshe bakala ukuthi ungakanani ugesi oguqulela ekushiseni nokuthi ungakanani oguqulela ekukhanyeni.

Wake wazibuza ukuthi kungakanani ukushisa okucisha izibani zakho? Abafundi base-Indiana University of Pennsylvania benza izibalo. Bathole ukuthi cishe u-80% kagesi kuma-incandescent bulb uguqulwa ube ukushisa, hhayi ukukhanya. Izibani ze-LED, ngakolunye uhlangothi, ziguqula u-80-90% kagesi wazo zibe ukukhanya, okuqinisekisa ukuthi amandla akho ngeke amoshe.

Okuhlala isikhathi eside

Izibani ze-LED nazo zihlala isikhathi eside. Izibani ze-LED zisebenzisa izinto ezihlukile kunezibani ze-incandescent. Ama-incandescent bulb ngokuvamile asebenzisa i-tungsten filament emincane. Le micu ye-tungsten ngemva kokusetshenziswa ngokuphindaphindiwe, ijwayele ukuncibilika, ukuqhekeka nokushiswa. Ngokuphambene, Izibani ze-LED zisebenzisa i-semiconductor kanye ne-diode, engenayo leyo nkinga.

Izingxenye eziqinile kumalambu okukhanya e-LED ahlala isikhathi eside ngendlela emangalisayo, ngisho nezimo ezinzima. Azikwazi ukumelana nokushaqeka, imithelela, isimo sezulu, nokuningi.

I E-US. Umnyango Wezamandla uqhathanise impilo ye-bulb emaphakathi yama-incandescent bulb, ama-CFL, nama-LED. Ama-incandescent bulbs endabuko athatha amahora angu-1,000 ngenkathi ama-CFL athatha amahora angu-10,000. Kodwa-ke, amalambu okukhanyisa e-LED athathe amahora angu-25,000 - lokho kuyizikhathi ezi-2 ½ ubude kunama-CFL!

Ama-LED Anikeza Ukukhanya Kwekhwalithi Engcono

Ama-LED agxilisa ukukhanya endaweni ethile ngaphandle kokusebenzisa izibonisi noma ama-diffuser. Ngenxa yalokho, ukukhanya kusatshalaliswa ngokulinganayo futhi kusebenza kahle.

Ukukhanyisa kwe-LED nakho kukhiqiza ukukhishwa okuncane kwe-UV noma ukukhanya kwe-infrared. Izinto ezibucayi ze-UV ezifana namaphepha amadala kumamnyuziyamu namagalari obuciko zihamba kangcono ngaphansi kokukhanya kwe-LED.

Njengoba ama-bulb esondela ekupheleni komjikelezo wabo wokuphila, ama-LED awamane ashe njengama-incandescent. Esikhundleni sokukushiya ebumnyameni ngokushesha, ama-LED ayancipha futhi afiphele aze aphume.

Ayinandaba nemvelo

Ngaphandle kokuwonga amandla kanye nokudweba izinsiza ezincane, izibani ze-LED nazo zilungele imvelo ukulahla.

Izibani ze-Fluorescent strip emahhovisi amaningi aqukethe i-mercury ngaphezu kwamanye amakhemikhali ayingozi. Lawa makhemikhali afanayo awakwazi ukulahlwa endaweni yokulahla udoti njengomnye udoti. Esikhundleni salokho, amabhizinisi kufanele asebenzise abathwali bemfucuza ababhalisiwe ukuze baqinisekise ukuthi izibani ze-fluorescent ziyanakekelwa.

Izibani ze-LED azinawo amakhemikhali anjalo ayingozi futhi ziphephile - futhi kulula! – ukulahla. Eqinisweni, izibani ze-LED zivame ukugaywa kabusha ngokuphelele.

Ukungalungi kwezibani ze-LED

Intengo Ephakeme

Izibani ze-LED zisewubuchwepheshe obusha obunezinto ezisezingeni eliphezulu. Babiza ngaphezudlwana kokuphindwe kabili kwentengo yozakwabo be-incandescent, okubenza babe utshalomali olubizayo. Nokho, abantu abaningi bathola ukuthi izindleko zizibuyisela ekongeni amandla esikhathini eside sokuphila.

Ukuzwela kwezinga lokushisa

Izinga lokukhanya kwe-diode lingancika ekushiseni kwe-ambient yendawo yabo. Uma isakhiwo esisetshenziswa izibani sivame ukuba nokwanda kwezinga lokushisa ngokushesha noma sinamazinga okushisa aphakeme ngendlela engavamile, isibani se-LED singasha ngokushesha.
