Ngoku singabona izibane ze-LED kuyo yonke indawo, Esitratweni, kwivenkile enkulu,
kwifektri nakwiofisi, egadini nasepakini... Kwaye ezinye izibane ze-LED zinomsebenzi okhethekileyo ofana nokukhanya kwe-LED okunceda izityalo zikhule ngokukhawuleza kunye nokukhanya kwe-UV kwe-LED okunomsebenzi wokubulala iintsholongwane kunye nokubulala iintsholongwane, Ukukhanyisa ukukhanya kwe-UV kwe-LED ekhaya kuya kuba kukhuselekileyo ngexesha le-COVID-19. Ndingavakalelwa kukuba izibane ze-LED zisijikelezile.Kutheni ukukhanya kwe-LED kuthatha indawo yezibane ze-Incandescent ngokukhawuleza kangaka?
Okokuqala, sazise umahluko phakathi kwezibane ze-Incandescent kunye nezibane ze-fluorescent, kunye nezibane ze-LED.
● Isibane esikhanyayo
Isibane esikhanyayo sikwabizwa ngokuba yi-Edison bulb, sisebenza ngokusebenzisa umbane nge-filament (tungsten, enyibilikayo kwi-3,000 degrees Celsius) evelisa ubushushu. I-spiral igcina ubushushu buxineneyo, nto leyo eyenza i-filament iphole ukuya kubushushu obungaphezulu kwe-2,000 degrees Celsius. Xa i-filament ikhanya, i-filament ikhupha ukukhanya okufana nentsimbi ebomvu ekhazimlayo. Okukhona ubushushu be-filament buphezulu, kokukhona ukukhanya kukhanya ngakumbi.
Ngaphandle koko, umbala okhanyayo utyheli kuphela. Kwaye umbala wento engaphantsi kwesibane se-incandescent awukho yinyani ngokwaneleyo (iRa iphantsi kakhulu). Ubomi bayo abude kangako ngenxa ye-Tungsten filament sublimation.
●Isibane se-fluorescent
Umgaqo wayo osebenzayo: ityhubhu yesibane se-fluorescent kuthiwa yityhubhu yokukhupha igesi evaliweyo. Igesi ephambili kwityhubhu yigesi ye-argon (argon) (ekwaqulathe i-neon okanye i-Krypton) malunga ne-0.3% yomoya-moya. Ikwanazo namathontsi ambalwa esilivere -- enza umphunga omncinci we-mercury. Ii-athomu ze-mercury zenza malunga newaka lee-athomu zegesi.
Izibane ze-fluorescent zinezibonelelo zokusebenza kakuhle kokukhanya okuphezulu (ngokuphindwe kahlanu kunezibane eziqhelekileyo), isiphumo esicacileyo sokonga amandla, ubomi obude (ngokuphindwe kasibhozo kunezibane eziqhelekileyo), ubungakanani obuncinci, kunye nokusetyenziswa okulula. Ukongeza kukukhanya okumhlophe, kukwakho nokukhanya okufudumeleyo. Ngokubanzi, phantsi kwe-wattage efanayo, isibane esonga amandla sigcina amandla nge-80% kunesibane esikhanyayo, kwaye ubude bobomi obuqhelekileyo buphindwe kasibhozo. I-5w ilingana ne-25 watts yezibane ezikhanyayo, ii-watts ezisi-7 zilingana ne-40 watts, kwaye ii-watts ezisi-9 zilingana ne-60 watts.
●Izibane ze-LED
Izibane ze-LED zikwabizwa ngokuba zii-diode ezikhupha ukukhanya. Sisixhobo se-semiconductor esiqinileyo esikhupha amandla ngendlela yee-photon kwaye siguqule umbane ngokuthe ngqo ube kukukhanya. Lo ngumgaqo wokukhanya kwe-LED.
Izibane ze-LED zineengenelo ezininzi
1. ubungakanani obuncinci
2. ukusetyenziswa kwamandla okuphantsi
3.Ixesha elide lobomi
4.engenabungozi
5. ukhuseleko lokusingqongileyo
Izibane ze-LED ziye zaphuhliswa kancinci kancinci ukusuka ekuhombiseni ngaphandle nasekukhanyiseni kobunjineli ukuya ekukhanyiseni kwasekhaya.
Ngoku ungaqonda ukuba kutheni izibane ze-LED zithandwa kangaka, kwaye utshintshe isibane sendabuko ngokukhawuleza. Njengomthengisi wezibane ze-LED, iGermany Liper Lighting ngumvelisi ochwephesha kushishino lwe-LED kangangeminyaka engaphezu kwama-29. Ukususela kuyilo ukuya kwimveliso ukuya kwintengiso, sinikezela ngenkonzo enye. Wamkelekile ukunxibelelana nathi ukuze ufumane ulwazi oluthe kratya.
