Izibane ze-LED, okanye i-Light-Emitting-Diodes, bubuchwepheshe obutsha.Isebe lezaMandla laseMelikaidwelisa iiLED “njengobona bugcisa banamhlanje bonga umbane nobukhula ngokukhawuleza.” Ii-LED ziye zaba sisikhanyiso esitsha esithandwayo samakhaya, iiholide, amashishini, kunye nokunye.

Izibane ze-LED zineenzuzo ezininzi kunye nokungonakali okumbalwa. Uphando lubonisa ukuba izibane ze-LED zinamandla, zihlala ixesha elide, kwaye zikumgangatho ophezulu. Kwinqanaba labathengi kunye neshishini, ukutshintshela kwii-LED konga imali kunye namandla.

Siqokelele iinzuzo eziphezulu kunye nokungalunganga kwezibane ze-LED. Qhubeka ufunda ukuze ufunde ukuba kutheni ingumbono oqaqambileyo ukutshintshela kwizibane ze-LED.

Izinto eziluncedo kwizibane ze-LED

Izibane ze-LED zisebenza ngokufanelekileyo

Izibane ze-LED zidume ngokuba namandla ngakumbi kunezo zandulelayo. Ukumisela ukusebenza kakuhle kombane kwiibhalbhu zokukhanya, iingcali zilinganisa ukuba ungakanani umbane oguqulwa ube bubushushu kwaye ungakanani na oguqulwa ube sisibane.

Ngaba wakha wazibuza ukuba zingakanani ubushushu obucinywa zizibane zakho? Abafundi beYunivesithi yase-Indiana yasePennsylvania benze izibalo. Baye bafumanisa ukuba ukuya kuthi ga kwi-80% yombane kwiibhalbhu ze-incandescent uguqulelwa kubushushu, hayi ukukhanya. Izibane ze-LED, kwelinye icala, ziguqula i-80-90% yombane wazo zibe ukukhanya, ziqinisekisa ukuba amandla akho akayi kuchitha.

Ihlala ixesha elide

Izibane ze-LED zihlala ixesha elide. Izibane ze-LED zisebenzisa izinto ezahlukeneyo kunezibane ze-incandescent. Iibhalbhu ze-incandescent zisebenzisa i-tungsten filament encinci. Ezi filaments ze-tungsten emva kokusetyenziswa ngokuphindaphindiweyo, ziyakwazi ukunyibilika, ukuqhekeka kunye nokutshisa. Ngokwahlukileyo, izibane ze-LED zisebenzisa i-semiconductor kunye ne-diode, engenayo loo nto.

Izinto ezomeleleyo kwiibhalbhu ze-LED zomelele ngokumangalisayo, kunye neemeko ezirhabaxa. Ziyakwazi ukumelana nokothuka, iimpembelelo, imozulu, nokunye.

I US. ISebe lezaMandla lithelekise umndilili wobomi beebhalbhu ze-incandescent, ii-CFL, kunye nee-LED. Iibhalbhu zesiqhelo zokugquma zahlala iiyure ezili-1,000 ngelixa ii-CFL zahlala iiyure eziyi-10,000. Nangona kunjalo, iiglowubhu ze-LED zithathe iiyure ezingama-25,000 - oko kukuphindaphinda nge-2 ½ ubude kuneCFL!

I-LED ibonelela ngokuKhanya okuBulunga obungcono

Ii-LED zigxininisa ukukhanya kwicala elithile ngaphandle kokusebenzisa izibonisi okanye i-diffusers. Ngenxa yoko, ukukhanya kuhanjiswe ngokulinganayo kwaye kusebenza kakuhle.

Ukukhanya kwe-LED kukwavelisa kancinci ukukhutshwa kwe-UV okanye ukukhanya kwe-infrared. Izixhobo ezibuthathaka ze-UV ezifana namaphepha amadala kwiimyuziyam kunye neegalari zobugcisa zihamba ngcono phantsi kokukhanya kwe-LED.

Njengoko iibhalbhu zisondela esiphelweni somjikelo wabo wobomi, ii-LED azitshi nje ziphele njengezikhanyisi. Endaweni yokukushiya ebumnyameni ngoko nangoko, ii-LED ziya zisiba mnyama kwaye zibe mnyama de ziphume.

Indawo intle

Ngaphandle kokusebenza kakuhle kwamandla kunye nokuzoba izibonelelo ezincinci, izibane ze-LED zikwayinto eco-friendly ukulahla.

Izibane ze-Fluorescent strip kwiiofisi ezininzi ziqulethe i-mercury ngaphezu kwezinye iikhemikhali eziyingozi. Kwa ezi khemikhali zinye azinakulahlwa kwindawo yokulahla inkunkuma njengenye inkunkuma. Endaweni yoko, amashishini kufuneka asebenzise abathwali benkunkuma ababhalisiweyo ukuqinisekisa ukuba imicu yokukhanya ye-fluorescent iyakhathalelwa.

Izibane ze-LED azinazo iikhemikhali ezinjalo eziyingozi kwaye zikhuselekile - kwaye zilula! - ukulahla. Enyanisweni, izibane ze-LED zihlala zihlaziywa ngokupheleleyo.

Ukungalungi kwezibane ze-LED

Ixabiso eliphezulu

Izibane ze-LED ziseyitekhnoloji entsha enezinto ezikumgangatho ophezulu. Baxabisa ngaphezu kwexabiso eliphindwe kabini kwiinkampani zabo ze-incandescent, okubenza babe lutyalo-mali olubiza kakhulu. Nangona kunjalo, abantu abaninzi bafumanisa ukuba iindleko ziyazibuyisela ekongeni amandla kubomi obude.

Uvakalelo lobushushu

Umgangatho wokukhanya kwe-diode unokuxhomekeka kwiqondo lokushisa kwindawo yazo. Ukuba isakhiwo esisetyenziswayo izibane sithande ukonyuka ngokukhawuleza amaqondo obushushu okanye amaqondo obushushu aphezulu ngokungaqhelekanga, ibhalbhu ye-LED inokutsha ngokukhawuleza.
