Uma ufuna ukwaziIndlela isibani se-LED esisebenza ngayo? Kule ndatshana sethula yonke imininingwane evelele yalolu hlobo lwesibani noma isibani, esisinikeza ukukhanya okumhlophe okumnandi, okusizuzisayo, kuhlala iminyaka eminingi futhi kudla amandla amancane kakhulu. Ngakho-ke ngenxa yalokhu, ama-incandescent bulbs anyamalele.
Funda ngezinzuzo nokusetshenziswa kwama-LED.
Ngabe isibani se-LED sisebenza kanjani?
Ngesikhathi u-Albert Einstein ethola uNobel Prize kuFizikiki, kwakungekhona ngombono wakhe wokuhlobana, lokhu kwakubangelwa isifundo esinesizotha, njengomphumela we-photoelectric. U-Einstein ubhale lokhu ukuthi ezinye izinto zokwakha, lapho zinikwa amandla okukhipha amandla kagesi wamanje.
Ukukhanya okukhiqizwa ngomphumela we-photoelectric kunemvamisa ethile, okungukuthi, umbala owodwa, oncike ohlotsheni lwento esetshenzisiwe. Kunemiphumela ephikisanayo kulokhu, edala ama-solar panel (photovoltaic) akhiqiza ugesi uma ekhanyiselwa ukukhanya.
Ama-diode e-LED abaziwa iminyaka engaphezu kwengu-60, lawa angama-LED abomvu naluhlaza atholakala kuwo wonke amadivayisi kagesi. Ngaphakathi kukapulasitiki we-diode ye-LED, singathola okokusebenza kwe-semiconductor. Uma isetshenziswa kumandla kagesi, lapho i-current idlula ku-semiconductor ikhiqiza ukukhanya.
Lokhu kukhanya kukukhipha ngaphandle kokukhiqiza cishe ukushisa, futhi ngombala osuvele unqunyiwe, ngokuya ngezinto ze-semiconductor, ukukhanya kombala owodwa noma komunye kuzokhishwa. Lo mbala ungabonakala emehlweni omuntu, kuphela ama-LED angaphansi kwe-infrared, atholakala kuzilawuli ezikude ze-TV.
Sisebenza kanjani isibani seLE: Izinhlobo zamalambu?
Singathola zonke izinhlobo zamalambu ahlukahlukene, njengama-globe bulbs, i-sphere yamakhandlela nezinhlobo ezi-2 ezihlukile zokuhlehlisa nokugcina ama-halogen amadala. Izinhlobo ezimbili esingazithola yilezi: ama-GU10 LED bulbs asebenza ku-230V, kumandla kagesi ajwayelekile emakhaya nama-MR16 noma ama-GU5 LED ama-bulb asebenza ne-12V kanye nama-halogen.
Shintsha i-Halogen yeLed
Kulula kakhulu ukushintsha i-halogen yesibani se-LED, kepha qaphela kakhulu. Into yokuqala okufanele yenziwe ukuthi, hlola ukuthi ama-halogen wethu asebenza kumaphi amandla? Kunezinhlobo ezi-2, lezo ezisebenza ku-12V futhi lezo ezisebenza ku-230V kanye nesimo ngasinye esihlukile.
Abanye abasebenza ku-12V futhi ngenxa yalesi sizathu bane-transformer yabo ekufakweni ukuguqula i-230V yekhaya ibe yi-12V. Ngakolunye uhlangothi sinalabo abasebenza ku-230V ngqo, kumbane wasekhaya. Kwezingu-12V, inketho yokuqala ukuqeda isiguquli, ibhuloho bese ufaka isibani nge-GU10 LED.
Inketho ehlukile ukushiya isiguquli futhi ushintshe ngqo isibani se-halogen seMR16 noma i-GU5 LED. Inketho engabizi kakhulu ukuqeda isiguquli ngokuvala ibhuloho, yize kungumsebenzi omkhulu kunenketho yesibili.
Izinzuzo ze-LED Bulbs
- Usayizi: Njengokukhanyisa, isibani se-LED sithatha isikhala esincane kunesibani se-incandescent.
- Ukukhanyisa
- Isikhathi: isibani se-LED singahlala amahora angama-50.000, okulingana neminyaka eyisithupha njalo kuqhubeke. Lokhu kuphindwe izikhathi ezingama-50 kunebani elikhanyayo le-incandescent.
- Ukusetshenziswa: irobhothi elishintshela kumalambu e-LED lizodla izikhathi eziphindwe ka-10 ngenani elifanayo lokukhanya okukhiqizwayo.
