Cov neeg nyob hauv nroog tau pom cov kev hloov tseem ceeb hauv kev saib xyuas thiab kho tshiab ntawm lub nroog' s txoj kev teeb pom kev zoo ntawm lub nroog.Muaj cov haujlwm uas tau ua tiav, dab tsi tau ua rau cov neeg nyiam nyiam tshaj plaws yog qhov hloov cov teeb qub nrog LED technology, uas muab cov kev pom pom zoo dua vim muaj qhov sib piv ntawm lub teeb dawb thiab muaj ntau yam ua tau zoo thiab txuag tau.
NYIAJ PUB ntawm LED Teeb
Lub teeb hluav taws xob diodes (LEDs) tau nrhiav pom xyoo 1960 los ntawm Robert Biard thiab Gary Pittman, thiab tsis ntev tau pib siv cov khoom siv sib txawv, xws li cov teeb pom kev zoo.
Cov thev naus laus zis tau hloov kho sai sai, thiab LED tau dhau los ua cov khoom siv hluav taws xob tseem ceeb ntawm ntau cov khoom siv thiab kev lag luam yooj yim thiab kev tiv thaiv ib puag ncig rau cov teeb hluav taws xob, ua qhov tseem ceeb ntawm kev hloov kho hauv kev lag luam teeb pom kev zoo, hloov cov teeb txawb thiab cov khoom siv rau hauv cov khoom siv hluav taws xob. ntau ua haujlwm.
LEDs yog cov khoom siv hluav taws xob, uas nws lub teeb tawm hluav taws xob tshwm sim dhau los ntawm kev kis kab hluav taws xob (electroluminescence). Qhov no yog qhov sib txawv ntawm LED los ntawm cov teeb pom kev zoo ib txwm, xws li lub teeb roj incandescent, uas tawm lub teeb los ntawm lub ntsiab lus tso cua sov, thiab fluorescent sawv daws yuav, uas tsim teeb pom kev los ntawm hluav taws xob tso tawm hauv cov pa mercury.
Cov thev naus laus zis thev naus laus zis tau ua tag nrho cov txheej txheem kev tsim teeb txawb, teeb tsa, luminaires thiab lwm yam khoom siv hluav taws xob pheej yig dua, dhau los tsim nyog los tsim cov teeb txawb, teeb tsa thiab luminaires. Ntxiv rau kev ua kom pheej yig dua, LED muaj ntau cov txiaj ntsig thaum cuam tshuam nrog lwm cov qauv teeb pom kev zoo, xws li lub teeb roj teeb (uas tsis tuaj yeem tsim lossis muag hauv Brazil txij li xyoo 2016) thiab cov roj fluorescent.
