LED qhov taub teeb yog lub zog-cov khoom siv tau zoo uas siv lub teeb-emitting diodes (LEDs) ua lawv lub teeb ci. Lawv muaj kev ua haujlwm siab luminous thiab lub neej ntev, thiab tuaj yeem hloov kho rau ntau lub hom phiaj teeb pom kev zoo los ntawm kev siv cov reflectors sib txawv. Lub teeb tso zis yog softened los tiv thaiv glare los yog lwm yam kev pom tsis xis nyob. Lub ballast suav nrog cov thev naus laus zis tiv thaiv hluav taws xob los xyuas kom cov khoom siv tau ntev. Cov reflectors yog tsim los ntawm imported, siab -purity, anodized specular aluminium thiab feature precision optical tsim; lub kaw lus boasts lub hwj chim tshaj tshaj 0.9, siab reflection efficiency, zoo heev lub teeb kis tau tus mob, thiab eco- phooj ywg zog txuag.
Kev sib piv ntawm LEDs thiab cov teeb pom kev zoo ib txwm muaj: LEDs yog cov khoom siv- xeev cov khoom siv hluav taws xob uas hloov hluav taws xob ncaj qha rau hauv lub teeb. Piv rau txoj kev ib txwm muaj thiab qhov chaw teeb pom kev zoo (xws li cov teeb sodium thiab hlau -halide teeb), LEDs muaj cov txiaj ntsig hauv qab no:
(1) Lub teeb pom kev tsis zoo: Nyob rau hauv cov cua kub zoo, cov teeb pom kev zoo LED tseem nyob ruaj khov; tus nqi lwj yog 3%–10% tshaj li thawj 10,000 teev thiab kwv yees li 30% tshaj 50,000 teev-cov duab qis dua li cov teeb pom kev zoo ntawm txoj kev.
(2) High colour rendering: LEDs feem ntau muaj xim rendering Performance index (CRI) ntawm 70–80 (los yog siab dua thaum siv tri-phosphor coatings), whereas siab - siab sodium teeb feem ntau yog li ntawm 20 mus rau 35, thiab qis - siab sodium teeb txawm qis dua. Yog li ntawd, txawm tias ib txwm muaj teeb pom kev zoo tshwm sim dua li LEDs, qhov pom tseeb tseeb uas tau muab los ntawm LEDs yog qhov zoo dua. "Tsis tas yuav yog qhov ci ntsa iab tshaj plaws, tab sis muab qhov pom tseeb tshaj plaws" sawv cev rau cov kev taw qhia tseem ceeb rau kev txhim kho thiab kev siv ntawm LED teeb pom kev zoo.
(3) Lifespan: LEDs muaj lub neej ntev dua li txoj kev thiab qhov chaw teeb pom kev zoo, feem ntau tshaj 50,000 teev.
(4) Nqe: Txawm hais tias LED fixtures tam sim no muaj tus nqi pib ntau dua li cov teeb pom kev zoo ib txwm muaj, cov nqi tau poob qis vim tias kev tsim khoom siv technology matures. Tus qauv siab - lossis qis- siab sodium teeb teeb feem ntau raug nqi nyob ib ncig ntawm 2,000 RMB, thiab cov nqi cuam tshuam rau cov cables thiab cov khoom siv pabcuam yog siab dua li qhov xav tau rau LED systems.
