Zisebenza Kanjani Izibani Ze-Led Street

Zisebenza Kanjani Izibani Ze-LED Street?

Ukukhanyisa emgwaqweni sekuhambe ibanga elide kusukela ezinsukwini zakuqala zamalambu egesi namalambu e-incandescent. Namuhla, izibani zomgwaqo ze-LED ziyizinga eliphelele - futhi ngesizathu esihle. Awonga amandla, ahlala isikhathi eside futhi ayabiza. Eqinisweni, izindawo eziningi zasemadolobheni emhlabeni jikelele zishintshele ekukhanyisweni komgwaqo we-LED ukuze zonge ukusetshenziswa kwamandla nokunciphisa ukukhishwa kwekhabhoni.

Kodwa zisebenza kanjani kahle izibani zomgwaqo ze-LED? Ake singene kwisayensi nobuchwepheshe ngemuva kwalezi zimangaliso zesimanje zokukhanya.

Isihlokwana: Ukusuka ku-Incandescent kuya ku-LED

Ngaphambi kokuthi singene endleleni amalambu e-LED asebenza ngayo, ake sibheke ngokushesha umlando wokukhanyisa emgwaqweni. Kusukela ekuqaleni kwawo-1800, izibani zegesi zazikhanyisa imigwaqo yedolobha. Kwaze kwaba ngasekupheleni kwawo-1800 lapho izibani zasemgwaqweni zikagesi zaqala ukugqama. Kodwa-ke, izinguqulo zakuqala zezibani zasemgwaqweni zikagesi zasebenzisa izibani ze-incandescent, ezingewona amandla kakhulu noma ahlala isikhathi eside.

Khona-ke, ngawo-1960, kwasungulwa i-light emitting diode (LED) yokuqala. Kodwa-ke, kwaze kwaba ngama-1990s lapho ukukhanya kwe-LED kwaqala ukungena embonini yokukhanyisa emgwaqweni. Manje, izibani zomgwaqo ze-LED ziyindinganiso emadolobheni amaningi emhlabeni jikelele.

Isihlokwana: Izingxenye Ezibalulekile Zezibani Zomgwaqo ze-LED

Ngaphambi kokuthi sibheke ukuthi izibani zasemgwaqweni ze-LED zisebenza kanjani, sidinga ukuqonda izingxenye eziyisisekelo zalezi zibani zokukhanyisa. Nazi izingxenye ezine eziyinhloko:

- Ama-LED chips: Lena imithombo emincane yokukhanya ekhiqiza ukukhanya kwangempela.

- Umshayeli we-LED: Le ngxenye ilawula amandla anikezwa ama-chips e-LED futhi isiza ukuqinisekisa ukuphuma okungaguquki.

- I-Heat sink: Izibani zasemgwaqweni ze-LED zikhiqiza ukushisa, ngakho-ke i-sink yokushisa iyadingeka ukuze iwuhlakaze futhi ugcine izibani zingashisi ngokweqile.

- Isistimu yokubona: Lokhu kuhlanganisa isibonisi kanye nelensi, esiza ukuqondisa ukukhanya lapho kudingeka khona.

Isihlokwana: Isayensi Engemuva Kwezibani Ze-LED Street

Ngakho-ke, amalambu omgwaqo e-LED asebenza kanjani? Konke kuncike kwisayensi yama-semiconductors. Ubuchwepheshe be-LED busebenzisa ama-semiconductors ukuguqula amandla kagesi abe ukukhanya. Lapho ugesi ugeleza nge-semiconductor, ukhipha amandla ngendlela yama-photons. Umbala wokukhanya uncike ohlotsheni lwe-semiconductor esetshenzisiwe.

Ama-LED awonga kakhulu amandla kunama-incandescent bulbs ngoba aguqula cishe wonke amandla awasebenzisayo abe ukukhanya. Ngakolunye uhlangothi, ama-incandescent bulbs akhiqiza ukushisa okukhulu, okuwukuphela kwamandla. Lokhu kwenza izibani zasemgwaqweni ze-LED zingabizi kakhulu kunezandulelayo ze-incandescent.

Isihlokwana: Izinzuzo Zezibani Ze-LED Street

Izibani zomgwaqo ze-LED zinikeza izinzuzo eziningi ngaphezu kwezinye izinhlobo zezibani zomgwaqo. Nazi ezinye zezinzuzo ezibalulekile:

- Ukonga ugesi: Izibani zasemgwaqweni ze-LED zisebenzisa amandla amancane kakhulu kunama-incandescent amalambu ngisho nezibani ze-fluorescent.

- Ihlala isikhathi eside: Izibani zasemgwaqweni ze-LED zingahlala amahora afika ku-100,000, okude kakhulu kunezinye izinhlobo zokukhanyisa.

- Ukunakekelwa okuphansi: Ngenxa yokuthi izibani zasemgwaqweni ze-LED zihlala isikhathi eside, zidinga ukulungiswa okuncane kunezinye izinhlobo zamalambu asemgwaqweni.

- Ukukhipha okuphansi: Izibani zasemgwaqweni ze-LED zikhipha i-CO2 encane kakhulu nokunye ukungcola kunezinye izinhlobo zezibani zasemgwaqweni.

- Kuyaqondiswa: Izibani zasemgwaqweni ze-LED zingaqondiswa ngokunembe kakhulu kunezinye izinhlobo zokukhanyisa, okusho ukuthi zingakhanyisa izindawo ezithile ngempumelelo.

Isihlokwana: Izinhlelo zokusebenza zezibani ze-LED Street

Izibani zomgwaqo ze-LED zisetshenziswa ezindaweni ezihlukahlukene, kusukela emadolobheni amakhulu kuya emigwaqweni emikhulu yasemakhaya. Nazi ezinye zezinhlelo zokusebenza ezivame kakhulu zezibani zomgwaqo ze-LED:

- Imigwaqo yasemadolobheni: Amadolobha amaningi amakhulu emhlabeni jikelele aguqule ukukhanya kwe-LED emgwaqweni ukunciphisa ukusetshenziswa kwamandla kanye nezindleko eziphansi.

- Imigwaqo emikhulu: Izibani zasemgwaqweni ze-LED zisetshenziswa emigwaqweni enguthelawayeka kanye nezinhlelo ezimaphakathi ukuze zinikeze ukubonakala okungcono nokunciphisa izingozi.

- Izindawo zokuhlala: Amalambu asemgwaqweni ama-LED nawo adumile ezindaweni zokuhlala ngoba angaqondiswa ukuze akhanyise izindawo ezithile ngaphandle kokuchithekela ezakhiweni ezingomakhelwane.

- Izindawo zokupaka: Izindawo eziningi zokupaka zikhanyiswa ngamalambu asemgwaqweni e-LED ngoba azonga futhi awonga ugesi.

Isihlokwana: Ekuphetheni

Izibani zasemgwaqweni ze-LED ziyi-innovation emangalisayo emkhakheni wokukhanyisa. Awonga amandla, ahlala isikhathi eside futhi angabizi, awenze afaneleke ezinhlobonhlobo zezinhlelo zokusebenza. Ngokuqonda ukuthi amalambu omgwaqo e-LED asebenza kanjani kanye nezinzuzo ezibalulekile ezinikezayo, ungawazisa kangcono umthelela ezinawo emadolobheni amakhulu namadolobhana emhlabeni jikelele.
