Ukuba ufuna ukwaziIndlela isibane se-LED esisebenza ngayo? Kule nqaku sinikezela zonke iinkcukacha ezibalaseleyo zolu hlobo lwesibane okanye ibhalbhu, esisinika ukukhanya okumhlophe okumnandi okuhlala kuthi iminyaka emininzi kwaye kudle amandla amancinci kakhulu. Ke ndiyabulela koku, ii-bulb incandescent ziye zanyamalala.
Funda malunga noncedo kunye nokusetyenziswa kwee-bulbs ze-LED.
Isebenza njani isibane se-LED?
Ngexesha u-Albert Einstein efumene ibhaso likaNobel kwiFizikiki, yayingengombono wakhe wobudlelwane, oku kubulelwe kwisifundo esithobekileyo, njengempembelelo yeefotoelectric. U-Einstein ubhale le ndlela ezinye izinto, xa ziphantsi kombane okhupha ukukhanya.
Ukukhanya okuveliswa ngumphumo we-photoelectric kunamaxesha athile, oko kukuthi, umbala omnye, oxhomekeke kuhlobo lwezinto ezisetyenzisiweyo. Kukho iziphumo ezichaseneyo noku, ezibangela iiphaneli zelanga (photovoltaic) ezivelisa umbane xa zivelisiwe kukukhanya.
Ii-diode ze-LED bezisaziwa ngaphezulu kweminyaka engama-60, ezi zibomvu nezihlaza ii-LEDs ezifumaneka kuzo zonke izixhobo ze-elektroniki. Ngaphakathi kwekeplastiki yeedayidi ze-LED, sinokufumana izinto ze-semiconductor. Xa ifakwe kumbane wombane, xa okwangoku idlula kwi-semiconductor ivelisa ukukhanya.
Olu khanyiso luyakhupha ngaphandle kokuvelisa phantse ubushushu, kwaye ngombala osele umiselwe, kuxhomekeke kwinto yemiconductor, ukukhanya kombala omnye okanye omnye kuya kukhutshwa. Lo mbala unokungabonakali kwiliso lomntu, kuphela zii-infrared LEDs, ezifumaneka kulawulo lweTV kude.
Sisebenza njani isibane seLE: Iintlobo zezibane?
Singafumana zonke iintlobo zezibane ezahlukeneyo, njengamaglobhu eglowubhu, ibala lekhandlela kunye neentlobo ezi-2 ezahlukeneyo zokwenza ikhefu kunye nokugcina ii-halojeni ezindala. Iindidi ezimbini esinokuzifumana zezi: I-GU10 ii-bulbs ze-LED ezisebenza kwi-230V, kumbane oqhelekileyo kumakhaya kunye ne-MR16 okanye i-GU5 i-bulbs ze-LED ezisebenza nge-12V kunye nee-halogens.
Guqula iHalogen yeLed
Kulula kakhulu ukutshintsha i-halogen yesibane se-LED, kodwa ke lumka. Into yokuqala ekufuneka yenziwe kukujonga ukuba zeziphi ii-voltage ezisebenza kwii-halogens zethu? Kukho iindidi ezi-2, ezisebenza nge-12V kwaye ezisebenza kwi-230V nakwimeko nganye eyahlukileyo.
Abanye abasebenza kwi-12V kwaye ngenxa yesi sizathu banesiguquli sabo kufakelo lokuguqula i-230V yekhaya ibe yi-12V. Kwelinye icala sinabo basebenza kwi-230V ngokuthe ngqo, kumbane wasekhaya. Kwii-12V, ukhetho lokuqala kukususa isiguquli, ibhulorho kwaye ubeke isibane endaweni ye-GU10 LED.
Inketho eyahlukileyo kukushiya isiguquli kwaye utshintshe ngokuthe ngqo isibane se-halogen se-MR16 okanye i-GU5 LED. Olona khetho lufikelelekayo kukususa isiguquli ngokuvala ibhlorho, nangona ingumsebenzi ongaphezulu kunokhetho lwesibini.
Izinto eziluncedo zeeBhalbhu ze-LED
- Ubungakanani: Njengokukhanyisa, ibhalbhu ye-LED ithatha indawo encinci kunebhalbhu ye-incandescent.
- Ukuqaqamba: ii-diode ze-LED zikhanya ngaphezu kwebhalbhu eqhelekileyo, kwaye ngaphezulu, ukukhanya akubekelwanga kwinqanaba elinye, njengomsonto webhalbhu yokukhanyisa, kodwa idayode ikhanya ngendlela efanayo.
- Ixesha: I-bulb ye-LED inokuhlala iiyure ezingama-50.000, elingana neminyaka emithandathu ngokuqhubekayo. La maxesha angaphezulu kwama-50 ngaphezu kwebhalbhu yesibane sokukhanya.
- Ukusetyenziswa: ukukhanya kwetrafikhi okutshintshela kwiibhalbhu ze-LED kuya kudla amaxesha angama-10 ngaphantsi kwenani elifanayo lokukhanya okuvelisiweyo.
