Lub Mechanism ntawm LED Teeb Teeb

Lub incandescentlub teeb, uas tau teeb pom kev zoo rau peb lub tsev txij li xyoo 1800s, tau pib poob qis nrog txoj cai lij choj ntawm Zog Kev ywj pheej thiab kev ruaj ntseg ntawm xyoo 2007 los ntawm Thawj Tswj Hwm George W. Bush. Txoj cai lij choj tsis txwv kev siv, kev yuav khoom, muag, lossis kev tsim cov qhov muag teev; Hloov chaw, nws tau yuam kom cov teeb pom kev hauv tsev ua tiav 25 feem pua ​​​​nce hauv kev ua haujlwm, sib npaug rau 25 feem pua ​​​​ntawm kev siv hluav taws xob tsawg dua piv rau cov teeb pom kev zoo siv ntawm 40 thiab 100 watts ntawm lub zog. Lub teeb tsis muaj txiaj ntsig, uas tawm 90 feem pua ​​​​ntawm nws lub zog raws li cua sov, tau dhau los ua neeg tsis nyiam ntawm cov teeb meem nyiaj txiag thiab kev nyab xeeb.
Nrog rau qhov pib ntawm cov qauv teeb pom kev tshiab hauv xyoo 2012, cov kev hloov pauv tseem ceeb rau lub teeb pom kev zoo tau dhau los ua cov teeb pom kev zoo fluorescent (CFL) thiab lub teeb emitting diodes (LEDs). CFL ntsib cov teeb meem tshwm sim, feem ntau yog kev siv cov mercury txaus ntshai hauv nws txoj kev tsim kho thiab qhov txawv txav, qee zaus tsis pom zoo xim uas tuaj yeem ua rau mob migraines hauv qee tus neeg.

Qhia covLED teeb.

LEDs muaj nyob rau ntau xyoo, illuminating lub moos digital, Christmas teeb, teeb nyem, teeb liab, thiab lwm yam. Txawm li cas los xij, hais txog kev teeb pom kev hauv tsev, LEDs tsis tau txais traction. Cov kev txwv tshwj xeeb tau tiv thaiv cov tuam txhab los ntawm kev tsim lawv nyob rau hauv ib txwm, hloov pauv - qhov loj me teeb teeb teeb. Hauv kaum xyoo dhau los, LED hloov qhov muag teev, uas tuaj yeem yooj yim screwed rau hauv cov teeb xws li incandescent qhov muag teev, tau loj hlob tuaj ntawm cov tuam txhab thiab tsev neeg.

Ib qho kev tshawb fawb xyoo 2017 tau qhia tias 70 feem pua ​​​​ntawm cov neeg Asmeskas tau yuav tsawg kawg yog ib lub teeb ci LED, thaum 38 feem pua ​​​​tau hloov ntawm lub teeb ci mus rau LEDs. Qhov kev faib ua feem no tau xav tias tau nce txij li xyoo 2017.

Kab lus no tshuaj xyuas qhov ua haujlwm ntawm LED qhov muag teev, lawv qhov kev thov raws li kev xaiv teeb pom kev zoo, thiab qhov cuam tshuam zoo thiab qhov tsis zoo. Cia peb pib nrog cov hauv paus ntsiab lus: Dab tsi yog lub tshuab uas LED tsim lub teeb?

Cov ntsiab lus ntawmLED Teeb Lub Teeb

Ib qho LED tau muab cais ua "khoom- teeb pom kev zoo" thev naus laus zis, lossis SSL. Qhov tseem ceeb, es tsis yog tsim lub teeb los ntawm lub tshuab nqus tsev (xws li nyob rau hauv lub teeb incandescent) lossis roj (raws li hauv CFL), khoom siv hluav taws xob- lub xeev teeb pom kev zoo (SSL) tsim lub teeb los ntawm cov khoom siv. Nyob rau hauv cov piv txwv ntawm ib tug pa LED, cov khoom nyob rau hauv nqe lus nug yog ib tug semiconductor.
Ib qho LED tsim lub teeb thaum hluav taws xob tam sim no hla lub microchip, illuminating lub minuscule teeb qhov chaw hu ua LEDs, ua rau pom lub teeb. Rau qhov kev qhia dav dav, mus rau Yuav Ua Li Cas Lub Teeb Emitting Diodes Function.
Qhov teeb meem nrog LEDs ua lub teeb pom kev hauv tsev yog qhov tseem ceeb, txawm hais tias lawv tsim teeb pom kev zoo, lawv cov qauv tsim ua rau ib feem ntawm lub teeb raug kaw nyob rau hauv lub fixture. Keeb kwm, LED qhov muag teev tsis tshua muaj luminous tshaj qhov muag teev, thiab feem ntau ntawm cov tib neeg nyiam lawv lub teeb thiab qab nthab fittings kom emit brightness ntau heev.
LED teeb tau ua kom ci dua. LED hloov qhov muag teev tam sim no muaj nyob rau uas tsim qhov ci ci piv rau 60-watt incandescent teeb lossis ntau dua, ua rau lawv cov kev daws teeb meem rau cov teeb pom kev zoo hauv tsev. Lub LED hloov lub teeb muaj lub neej ntev 24,000 teev ntau dua li cov khoom siv 60-watt incandescent teeb.
Ntxiv mus, nws yog kev lag luam ntau dua. Hloov tsib lub teeb pom kev zoo tshaj plaws hauv koj qhov chaw nyob nrog LED ENERGY STAR versions yuav tau txais txiaj ntsig txhua xyoo ntawm $ 75.
