Ngoku sibona izibane ezikhokelwayo kuyo yonke indawo, Esitratweni, kudederhu lweevenkile,
kumzi mveliso kunye neofisi, egadini nasepakini...Kwaye ezinye izibane ezikhokelwayo zinomsebenzi okhethekileyo onjengokukhanya okukhokelela ekukhuleni okunceda izityalo zikhule ngokukhawuleza kwaye zikhokele isibane se-UV esinokubulala iintsholongwane kunye nomsebenzi wokubulala inzala, Khanyisa isibane esikhokelwayo se-UV ekhaya siya ukhuseleke ngakumbi ngexesha le-COVID-19. Ndiziva ngathi izibane ezikhokelwayo zisijikelezile.Kutheni izibane ezikhokelayo zitshintshe izibane ze-Incandescent ngokukhawuleza?
Okokuqala, masazi umahluko phakathi kwezibane ze-Incandescent kunye nezibane ze-fluorescent, kunye nezibane ezikhokelayo.
● Isibane se-incandescent
Isibane se-incandescent sikwabizwa ngokuba yibhalbhu ye-Edison, Isebenza ngokuqhuba umsinga wombane ngokusebenzisa i-filament (i-tungsten, inyibilika kwi-3,000 degrees Celsius) eyenza ubushushu. I<em>spiral igcina ubushushu bugxile, nto leyo eyenza i<em>filament iphole ukuya kumaqondo obushushu angaphezu kwama-2 000 ngokukaCelsius. Xa i-incandescent, i-filament ikhupha ukukhanya okufana nentsimbi ebomvu ekhazimulayo. Okukhona ubushushu bomsinga, kokukhona ukukhanya kuqaqambile.
Ngaphandle koko, Umbala okhanyayo kuphela otyheli. Kwaye umbala wento phantsi kwesibane se-incandescent ayinyani ngokwaneleyo (i-Ra iphantsi kakhulu). Ubomi bonke abukho kude kangako ngenxa ye-Tungsten filament sublimation.
●Isibane seFluorescent
Umgaqo wayo wokusebenza: ityhubhu yesibane se-fluorescent kuthiwa nje ityhubhu yokukhupha igesi evaliweyo. Irhasi ephambili kwi-tube yi-argon (argon) igesi (equlethe neon okanye iKrypton) malunga ne-0.3% ye-atmosphere. Ikwanayo namathontsi ambalwa esilivere -- yenza umphunga omncinci wemekyuri. Iiathom zeMercury zenza malunga newaka leeathom zegesi.
Izibane ze-Fluorescent zineenzuzo zokukhanya okuphezulu okukhanyayo (amaxesha ama-5 eebhalbhu eziqhelekileyo), umphumo ocacileyo wokonga umbane, ubomi obude (amaxesha asi-8 eebhalbhu eziqhelekileyo), ubungakanani obuncinci, kunye nokusetyenziswa ngokufanelekileyo. Ukongeza ukukhanya okumhlophe, kukho ukukhanya okufudumeleyo. Ngokuqhelekileyo, phantsi kwe-wattage efanayo, isibane sokugcina amandla si-80% songa amandla kunesibane se-incandescent, kwaye umyinge wobomi buhlala ngamaxesha angama-8 ubude. I-5w ilingana ne-25 watts yezibane ze-incandescent, i-7 watts ilingana ne-40 watts, kwaye i-9 yatts ilingana ne-60 watts.
●Izibane zeLED
Izibane ze-LED zikwabizwa ngokuba zii-diode ezikhupha ukukhanya. Isixhobo se-semiconductor yesimo esiqinileyo esikhupha amandla ngendlela yeefotoni kwaye siguqule ngokuthe ngqo umbane ekukhanyeni. Lo ngumgaqo wokukhanyisa kwe-LED.
Izibane ze-LED zineenzuzo ezininzi
1.ubungakanani obuncinci
2.ukusetyenziswa kwamandla aphantsi
3.ixesha elide lobomi
4.engenatyhefu
5.ukhuseleko lokusingqongileyo
Izibane ze-LED ziye zaphuhliswa ngokuthe ngcembe ukusuka ekuhombiseni kwangaphandle kunye nezibane zobunjineli ukuya kwizibane zendlu.
Ngoku unokuqonda ukuba kutheni izibane ezikhokelayo zithandwa kangaka, kwaye utshintshe isibane semveli ngokukhawuleza. Njengomboneleli wezibane ezikhokelwayo, iJamani iLiper Lighting yimveliso enobuchwephesha kumzi-mveliso okhokelwayo ngaphezulu kwe-29years. Ukusuka kuyilo ukuya kwimveliso ukuya kwiintengiso, sibonelela ngenkonzo yokuyeka enye.Wamkelekile ukunxibelelana nathi ngolwazi olungakumbi.
