Kutheni izibane ze-LED zinokugcina umbane kunye nokugcina iindleko?
Izibane zinoxanduva lokuthatha amandla amaninzi. Kwiinkampani ezinkulu kunye neefektri, iindleko zokukhanya kwansuku zonke zikhulu kangangokuthi azikwazi ukuhoywa, ngoko ke izibane ze-LED zizona zithandwa kakhulu endaweni yokutshintshwa kwe-HID. Ukugcinwa kwe-LED kunye neendleko zokusebenza ziphantsi kakhulu kunokukhanyisa kwendabuko. Ekubeni ukukhanya kuyinto ebalulekileyo, ukufumana indlela eyonga amandla ngakumbi yokukufumana kufanelekile ukuzama kuba kuya kuhlawula ngokukhawuleza okanye kamva.
Ukonga amandla yinkqubo yokwenyani nebalulekileyo enokuhlawula abantu phambi kokusingqongileyo. Abantu bebezama ukufumana izixhobo ezingcono zokusebenzisa amandla abo. Kwaye ezi zixhobo zingcono azithethi nje ukuba zikhuselekile ngakumbi kokusingqongileyo, kodwa zifikeleleka ngakumbi kwaye zisebenza ngakumbi kubathengi. Umzekelo, khawube nomfanekiso-ngqondweni wokuchitha imali encinci ekufudumezeni nombane ngaphandle kokunciphisa ukusetyenziswa kwesiqhelo.
Kodwa kwakhona kufuneka sazi ukuba kutheni izibane ze-LED zinokugcina amandla kunye nokugcina iindleko, izizathu ezicacileyo ziya kuboniswa kwesi sincoko.
Isizathu 1: Ubomi obuphezulu be-LED bunciphisa ukuphindaphinda kokutshintshwa
Ii-LED zomelele ngakumbi kunawo nawuphi na omnye umthombo wokukhanyisa. Xa kuthelekiswa nezibane ze-fluorescent kunye ne-incandescent bulbs, yangaphambili inokuhlala iiyure ze-8,000 kuphela, kwaye emva kweeyure ze-1000, ixesha eliqikelelwayo lokukhanya kwe-LED lidlula iiyure ezingama-80,000. Kuthetha ukuba izibane ze-LED zisebenza iintsuku ezili-10,000 ubude kunabo bakhuphisana nabo (okulingana neminyaka engama-27) kwaye ukutshintshwa kwesibane se-LED kube kanye kufana nokutshintsha ibhalbhu ye-incandescent eqhelekileyo amaxesha angama-80.
Isizathu sesi-2: Ukusebenza ngoko nangoko kunye nokucinywa kwezibane ze-LED zigcina zisebenza kakuhle
Ukongeza ekusebenziseni amandla, izibane ze-LED zinezinye iintlobo ezininzi zokukhanyisa, ezifana ne-metal halides, izibane ze-incandescent, kunye nezibane ze-fluorescent. Ziqala kwangoko kwaye azifuni ixesha elininzi lokufudumala njengezibane ze-fluorescent. Akukho ngxaki ngokuwavula nokuwacima rhoqo. Ayichaphazeli ukusebenza kwabo okanye ubomi obude. Ngokungafaniyo ne-CFL kunye nezibane ze-incandescent, aziqhekeki ngokulula ngenxa yokuba izinto ezisetyenziselwa ukwenza ziqinile kwaye azinabhobho okanye i-filament breakage. Ngoko ke, i-LED yomelele kwaye ayinayo i-fragile.
Isizathu sesi-3: Umgaqo wokusebenza we-LED unciphisa iindleko zokusebenza
Isibane se-Incandescent ngumthombo wokukhanya wombane onika amandla i-filament kwi-incandescent state kwaye ukhupha ukukhanya okubonakalayo ngemitha ye-thermal. Ngelixa i-LED (i-Light Emitting Diode) sisixhobo esiqinileyo se-semiconductor, esinokuguqula ngokuthe ngqo umbane ekukhanyeni. Ngoko nawuphi na omnye umthombo wokukhanyisa ubiza ngaphezu kwe-LED. Ngoko ke, akungabazeki ukuba zibiza imali eninzi kwixesha elide. Enye inkalo engenakungahoywa kukusetyenziswa kwamandla. Ukuba usebenzisa isibane se-incandescent kwiiyure ze-8 kunye neminyaka emi-2 ngosuku, kuya kukubiza malunga ne-$ 50, kodwa ukuba usebenzisa ii-LED zeeyure ze-8 kunye neminyaka emi-2 ngexesha elifanayo - liya kukubiza ngaphantsi ukuya kwi-$ 2 ukuya kwi-$ 4. Ingaba singagcina malini? Gcina ukuya kuthi ga kwi-48 yeedola ngonyaka kwaye wonge ukuya kuthi ga kwi-4 yeedola nge-LED nganye ngenyanga. Silapha ukuze sithethe ngebhalbhu enye. Kulo naliphi na ikhaya okanye izinto eziluncedo, iiglowubhu ezininzi zokukhanya zivulwa ixesha elide ngosuku, kwaye umahluko weendleko ngokwenene ufanele ukuqwalaselwa. Ewe, ixabiso lokuthengwa kwee-LED liphezulu, kodwa ixabiso elipheleleyo liphantsi kunezinye iintlobo zezibane, kwaye amaxabiso ayancipha ngokuhamba kwesikhathi. Kuphela nje ukuba iteknoloji idla ngokuza ngexabiso eliphezulu de imarike ilungelelaniswe ngokupheleleyo kuyo, kwaye ke ixabiso lemveliso liyehla.
