Tom qab ntau xyoo ntawm kev txhim kho kev txawj ntse, LED lub luminous efficiency tau zoo heev. Incandescent teeb, halogen tungsten teeb muaj luminous efficiency ntawm 12-24 lumens / watt, fluorescent teeb 50-70 lumens / watt, thiab sodium teeb 90-140 lumens / watt. Feem ntau ntawm kev siv hluav taws xob dhau los ua cua sov. Qhov txhim khoLED teebefficiency yuav ncav cuag 50-200 lumens / watt, thiab nws lub teeb muaj zoo monochromaticity thiab nqaim spectrum. Nws tuaj yeem ncaj qha tshaj tawm cov xim pom lub teeb yam tsis muaj kev lim dej.
Niaj hnub no, txhua lub teb chaws hauv ntiaj teb tab tom maj nrawm los txhim kho kev tshawb fawb ntawm LED teeb pom kev zoo, thiab lawv cov kev ua haujlwm luminous yuav zoo dua yav tom ntej. Nrog rau kev lag luam ntawm high-brightness LEDs ntawm ntau yam xim xws li liab, daj, thiab ntsuab, LEDs tau maj mam hloov cov tsoos incandescent teeb thiab tungsten halogen teeb raws liteeb tsheb. Txij li thaum lub teeb tshaj tawm los ntawm LED yog qhov tseem ceeb hauv cov khoom me me, tsis xav tau qhov cuam tshuam, thiab lub teeb tshaj tawm tsis xav tau lub lens xim los lim, yog li ntev npaum li lub lens parallel yog tsim los ntawm lub lens convex lossis Fresnel lens, tom qab ntawd lub lens pincushion tso cai rau cov nqaj kom tau diffused thiab deflected los ntawm lub taub hau kom tau raws li qhov xav tau ntawm lub teeb.
