Kev ua haujlwm ntawm Lub Teeb Emitting Diodes (LEDs)

PolychromaticLED teeb pom kev zoo

Multicolored LED teeb ci ntsa iab.

Lub teeb -emitting diodes, feem ntau hu ua LEDs, feem ntau raug saib tsis tau tab sis tseem ceeb hauv kev lag luam hluav taws xob. Lawv ua ntau txoj haujlwm thoob plaws ntau yam khoom siv. Lawv tsim cov lej ntawm cov duab digital, xa cov ntaub ntawv los ntawm cov chaw taws teeb tswj, teeb lub sijhawm, thiab qhia txog kev ua haujlwm ntawm cov khoom siv. Thaum sib sau ua ke, lawv tuaj yeem tsim qhov pom ntawm lub vijtsam TV loj lossis teeb pom kev tsheb khiav.

Qhov tseem ceeb

LEDsyog me me qhov muag teev uas seamlessly integrate rau hauv ib tug hluav taws xob Circuit Court. Nyob rau hauv sib piv rau incandescent teeb, lawv tsis muaj filaments uas yuav ua tsis tau tejyam, haus tsawg zog, thiab tsis ua kom muaj cua sov loj. Lawv tsuas yog ci ntsa iab los ntawm kev txav ntawm cov khoom siv hluav taws xob hauv cov khoom siv semiconductor, thiab lawv muaj lub neej zoo ib yam li cov pa transistor. Lub neej ntev ntawm ib qho LED tshaj li ntawm lub teeb incandescent los ntawm ntau txhiab teev. Vim cov txiaj ntsig no, cov me me LEDs yog cov cuab yeej nyiam tshaj plaws rau kev teeb pom kev zoo ntawm LCD TVs.
 

Kev ua tau zoo

LEDs muaj ntau yam txiaj ntsig piv rau cov teeb pom kev zoo, nrog rau lawv cov txiaj ntsig tseem ceeb yog kev ua haujlwm zoo. Incandescent qhov muag teev tsim lub teeb los ntawm lub tshuab uas ua kom muaj cua sov tseem ceeb, xav tau cov filament kom sov kom emit illumination. Lub zog no yog tag nrho squandered tshwj tsis yog tias lub teeb yog siv los ua kom sov, vim tias feem ntau ntawm cov khoom siv hluav taws xob tsis ua rau lub teeb pom kev zoo. LEDs tsim hluav taws xob tsawg dua hauv kev sib piv. Ib qho kev faib ua feem ntau ntawm cov hluav taws xob hluav taws xob yog siv ncaj qha rau lub teeb tsim, yog li txo qis kev siv hluav taws xob ntau.
LEDs tsim ntau dua lumen tso zis ib watt piv rau cov pa roj teeb incandescent.LED teebmuaj superior luminous efficiency, qhia ib tug ntau npaum hloov dua siab tshiab ntawm lub hwj chim rau pom lub teeb piv rau incandescent qhov muag teev. Lub 60-watt incandescent teeb ua ib ncig ntawm 750-900 lumens, tab sis ib lub teeb LED yuav ua tiav qhov sib npaug luminosity nrog qis dua 6-8 watts. Lub teeb LED tuaj yeem ua haujlwm ntev li 25,000 teev, thaum lub teeb 60-watt incandescent feem ntau siv sijhawm li 1,200 teev xwb. Hauv lwm lo lus, ib lub teeb ci LED tuaj yeem ua rau lub sijhawm sib npaug ntawm 21 txuas ntxiv siv 60-watt incandescent teeb.

Tsis ntev los no

LEDs tau txwv tsis pub kim rau feem ntau daim ntawv thov teeb pom kev zoo vim lawv tso siab rau cov khoom siv semiconductor sophisticated. Tus nqi ntawm cov khoom siv hluav taws xob semiconductor tau txo qis tom qab -2000, ua rau LEDs ua kom muaj teeb pom kev zoo dua rau ntau daim ntawv thov. Txawm hais tias lawv muaj tus nqi pib dua piv rau qhov muag teev (kwv yees $ 5 tawm tsam $ 1), lawv cov nqi qis dua tuaj yeem ua rau lawv muaj txiaj ntsig zoo dua. Ntau lub lag luam tau pib muagLED teeb qhov muag teevnpaj rau kev sib tw incandescent thiab compact fluorescent xaiv, uas thov kom muaj lub neej ntev, superior brightness, thiab exceptional zog kev khwv nyiaj txiag.
