Manje sesibona izibani ze-LED yonke indawo, Emgwaqweni, ezitolo ezinkulu,
efektri nasehhovisi, engadini nasepaki... Futhi ezinye izibani ze-LED zinomsebenzi okhethekile ofana nokukhanya kwe-LED okukhulisa izitshalo okusiza izitshalo zikhule ngokushesha kanye nokukhanya kwe-UV kwe-LED okunomsebenzi wokubulala amagciwane kanye nokubulala amagciwane, Ukukhanyisa ukukhanya kwe-UV kwe-LED ekhaya kuzophepha kakhulu ngesikhathi se-COVID-19. Ngingazizwa sengathi izibani ze-LED zisizungezile.Kungani ukukhanya kwe-LED kushintsha izibani ze-Incandescent ngokushesha kangaka?
Okokuqala, sazise umehluko phakathi kwezibani ze-Incandescent nezibani ze-fluorescent, kanye nezibani ze-LED.
● Isibani esikhanyayo
Isibani esikhanyayo sibizwa nangokuthi ibhalbhu ka-Edison, Sisebenza ngokusebenzisa ugesi nge-filament (i-tungsten, encibilika kuma-degree Celsius angu-3,000) ekhiqiza ukushisa. I-spiral igcina ukushisa kugxilile, okwenza i-filament iphole kuze kube yilapho izinga lokushisa lingaphezu kwama-degree Celsius angu-2,000. Uma i-incandescent, i-filament ikhipha ukukhanya njengensimbi ebomvu ekhazimulayo. Uma izinga lokushisa le-filament liphakeme, ukukhanya kukhanya kakhulu.
Ngaphandle kwalokho, umbala okhanyayo uphuzi kuphela. Futhi umbala wento engaphansi kwesibani se-incandescent awukho ngempela ngokwanele (i-Ra iphansi kakhulu). Isikhathi sokuphila asiside kangako ngenxa ye-Tungsten filament sublimation.
●Isibani se-fluorescent
Isimiso salo sokusebenza: ithubhu lesibani se-fluorescent kuthiwa nje lithubhu lokukhipha igesi elivaliwe. Igesi eyinhloko kuleli thubhu yigesi ye-argon (argon) (equkethe neon noma i-Krypton) cishe ku-0.3% womkhathi. Iqukethe namaconsi ambalwa esiliva -- akha umhwamuko omncane we-mercury. Ama-athomu e-mercury akha cishe ingxenye eyodwa kweziyinkulungwane yawo wonke ama-athomu egesi.
Izibani ezikhanyayo zinezinzuzo zokusebenza kahle kakhulu kokukhanya (okuphindwe kahlanu kunama-bulb avamile), umphumela osobala wokonga amandla, ukuphila isikhathi eside (okuphindwe ka-8 kunama-bulb avamile), usayizi omncane, kanye nokusetshenziswa okulula. Ngaphezu kokukhanya okumhlophe, kukhona nokukhanya okufudumele. Ngokuvamile, ngaphansi kwamandla afanayo, isibani esonga amandla songa amandla ngo-80% kunesibani esikhanyayo, futhi isikhathi sokuphila esimaphakathi siphindwe ka-8. I-5w ilingana nama-watts angu-25 ezibani ezikhanyayo, ama-watts angu-7 alingana nama-watts angu-40, kanti ama-watts angu-9 alingana nama-watts angu-60.
●Izibani ze-LED
Izibani ze-LED zibizwa nangokuthi ama-diode akhipha ukukhanya. Kuyidivayisi ye-semiconductor eqinile ekhipha amandla ngesimo sama-photon futhi iguqule ugesi ngqo ube ukukhanya. Lesi yisimiso sokukhanya kwe-LED.
Izibani ze-LED zinezinzuzo eziningi
1. usayizi omncane
2. ukusetshenziswa kwamandla okuphansi
3. isikhathi eside sokuphila
4. okungeyona into enobuthi
5. ukuvikelwa kwemvelo
Izibani ze-LED ziye zathuthuka kancane kancane kusukela ekuhlobiseni kwangaphandle kanye nokukhanyisa kobunjiniyela kuya ekukhanyiseni kwasekhaya.
Manje usuyaqonda ukuthi kungani izibani ze-LED zithandwa kangaka, bese ushintsha isibani sendabuko ngokushesha kangaka. Njengomhlinzeki wezibani ze-LED, i-Germany Liper Lighting ingumkhiqizi ochwepheshe embonini ye-LED iminyaka engaphezu kwengu-29. Kusukela ekuklanyweni kuya ekukhiqizweni kuya ekuthengisweni, sinikeza isevisi eyodwa kuphela. Siyakwamukela uxhumane nathi ukuze uthole ulwazi olwengeziwe.
Isikhathi sokuthunyelwe: Novemba-19-2020
