Qhov sib txawv ntawm Incandescent thiab LED Teeb
Hauv lub ntiaj teb niaj hnub nim no, kev nce qib ntawm thev naus laus zis tau coj peb ntau yam kev xaiv teeb pom kev zoo dua thiab zoo rau ib puag ncig. Ob hom teeb pom kev zoo uas feem ntau sib cav thiab piv rau yog cov teeb incandescent thiab lub teeb-emitting diode (LED). Txhua tus muaj cov yam ntxwv tshwj xeeb, kev siv sib txawv, thiab qhov zoo thiab qhov tsis zoo. Tsab xov xwm no yuav tshawb nrhiav qhov sib txawv ntawm ob hom teeb pom kev zoo no kom tob, suav nrog kev siv hluav taws xob zoo, lub neej teeb, tus nqi, thiab kev cuam tshuam rau ib puag ncig.
Keeb Kwm thiab Cov Ntsiab Cai Ua Haujlwm
Lub teeb incandescent yog ib hom teeb pom kev zoo qub tshaj plaws, uas Thomas Edison tau tsim thaum xyoo pua 19th. Nws ua haujlwm yooj yim: hluav taws xob ntws los ntawm cov tungsten filament hauv lub teeb iav, ua kom lub filament sov kom txog thaum nws ci thiab tsim lub teeb. Cov teeb incandescent paub txog lawv cov teeb ci sov, ntuj, uas zoo li lub teeb ntawm lub hnub lossis hluav taws.
Ntawm qhov tod tes, teeb LED yog ib qho thev naus laus zis tshiab dua, tau txais kev nyiam hauv xyoo pua 20th lig. LEDs tsim lub teeb los ntawm semiconductors uas tso tawm photons thaum hluav taws xob siv. Lub teeb LED los ntawm lub zog ntawm cov electrons txav mus los ntawm ib txoj kab hluav taws xob mus rau lwm qhov hauv cov ntaub ntawv semiconductor sib txawv, ib qho txheej txheem hu ua electroluminescence. LED thev naus laus zis txuas ntxiv hloov zuj zus, tsim cov teeb pom kev zoo dua, kav ntev dua, thiab ntau yam.
Kev Siv Hluav Taws Xob Zoo
Ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws ntawm cov teeb incandescent thiab LED yog kev siv hluav taws xob zoo. Cov teeb incandescent feem ntau tsis siv hluav taws xob zoo; tsuas yog li ntawm 10% ntawm lub zog hluav taws xob uas muab rau lawv hloov mus ua lub teeb pom kev, thaum cov seem - kwv yees li 90% - raug pov tseg ua cua sov. Yog li ntawd, cov teeb incandescent tsis yog tsuas yog pov tseg lub zog xwb tab sis kuj tso tawm cua sov ntau heev, uas tuaj yeem ua rau chav sov nce siab.
Qhov sib piv, cov teeb LED ua haujlwm tau zoo dua. Cov teeb LED tuaj yeem hloov pauv li 80-90% ntawm lub zog mus rau hauv lub teeb pom kev. Qhov no txhais tau tias cov teeb LED siv zog tsawg dua li cov teeb incandescent los tsim tib lub teeb. Qhov kev ua haujlwm zoo no tsis tsuas yog txo cov nqi zog xwb tab sis kuj txo cov cua sov hauv chav, ua rau lawv yog qhov kev xaiv zoo dua rau ib puag ncig thiab pheej yig dua rau kev siv mus sij hawm ntev.
Lub Neej Teeb
Lwm qhov txawv tseem ceeb ntawm cov teeb incandescent thiab LED yog lawv lub neej ntev. Cov teeb incandescent muaj lub neej luv luv, feem ntau kav ntev li ntawm 750 thiab 2.000 teev ua ntej lub filament tawg thiab lub teeb puas. Qhov no txhais tau tias cov teeb incandescent xav tau hloov ntau zaus, uas tuaj yeem ua rau cov nqi kho thiab hloov ntau ntxiv.
Qhov sib piv, cov teeb LED muaj lub neej ntev heev, kav ntev li 25.000 txog 50.000 teev lossis ntau dua, nyob ntawm qhov zoo thiab kev siv. Vim tias cov LEDs tsis muaj cov filament kom tawg, lawv ruaj khov dua. Tus nqi qis ntawm kev hloov cov teeb LED ua rau lawv pheej yig dua hauv lub sijhawm ntev thiab txo cov khoom siv hluav taws xob pov tseg.
Nqi
Txawm hais tias tus nqi pib ntawm cov teeb incandescent qis dua li cov teeb LED, kev xam tus nqi tag nrho lub neej yuav tsum xav txog kev siv hluav taws xob zoo thiab lub neej ntawm lub teeb. Cov teeb LED, txawm tias lawv tus nqi yuav siab dua, yuav txuag koj cov nyiaj ntau dua rau lub sijhawm ntev vim lawv siv hluav taws xob tsawg dua thiab lub neej ntev dua. Ntau yam kev txuag nyiaj mus sij hawm ntev yog los ntawm kev siv hluav taws xob tsawg dua thiab hloov lossis kho tsawg dua.
Lub teeb zoo
Cov teeb incandescent paub txog lawv qhov sov so thiab zoo ntawm lub teeb, feem ntau ntsuas los ntawm qhov kub xim ntawm kwv yees li 2700K (Kelvin). Lub teeb no ua raws li lub teeb ntuj thiab ua rau cov khoom nyob ib puag ncig zoo li ntuj dua. Lub teeb incandescent kuj muaj cov ntsuas xim siab heev (CRI), ncav cuag tus nqi ntawm 100, txhais tau tias nws tuaj yeem tso saib cov xim ntawm cov khoom kom raug heev.
Nyob rau hauv kev sib piv, LED teeb tuaj yeem tsim ntau yam xim kub, los ntawm sov heev (kwv yees li 2700K) mus rau txias heev (ntau tshaj 6000K). Ntxiv mus, LED thev naus laus zis tau nce qib mus txog qhov uas ntau yam khoom LED tam sim no muaj CRI siab, ze li ntawm cov teeb incandescent. Qhov kev hloov pauv ntawm qhov kub xim no tso cai rau LED teeb siv rau hauv ntau yam kev siv teeb pom kev zoo kom haum rau cov neeg siv xav tau thiab nyiam.
Kev Cuam Tshuam Ib puag ncig
Vim tias cov teeb incandescent tsis siv hluav taws xob ntau thiab siv tau ntev, nws muaj feem cuam tshuam rau ib puag ncig ntau dua. Kev siv hluav taws xob ntau txhais tau tias yuav tsum muaj ntau yam khoom siv los tsim hluav taws xob, ua rau muaj pa roj av thiab ua rau muaj kuab paug rau ib puag ncig ntau dua. Ntxiv mus, lawv lub neej luv ua rau muaj cov khib nyiab hluav taws xob ntau dua uas yuav tsum tau tswj hwm.
Ntawm qhov tod tes, cov teeb LED zoo dua rau ib puag ncig. Lawv siv hluav taws xob tsawg txo cov pa roj carbon thiab kev siv hluav taws xob. Lawv lub neej ntev kuj txhais tau tias txo qis cov khib nyiab hluav taws xob. Ntau yam khoom LED kuj tsis muaj cov khoom phom sij xws li mercury, uas feem ntau pom muaj nyob rau hauv cov teeb fluorescent.
Kev Sib Txawv ntawm Daim Ntawv Thov
Cov teeb incandescent feem ntau siv rau hauv cov ntawv thov uas xav tau lub teeb sov so, xws li tsev, khw noj mov, thiab qee qhov kev siv tshwj xeeb uas xav tau lub teeb spectrum tshwj xeeb. Txawm li cas los xij, vim lawv siv hluav taws xob tsawg thiab lub neej luv luv, lawv txoj kev siv tab tom poob qis.
Nyob rau hauv kev sib piv, cov teeb LED muaj ntau yam siv tau. Lawv tsim nyog rau ntau yam kev siv, los ntawm tsev neeg, kev lag luam, kev lag luam, thiab kev teeb pom kev zoo rau txoj kev mus rau cov kev siv tshwj xeeb xws li kev kho mob lossis kev ua liaj ua teb teeb pom kev zoo. LEDs kuj tseem tuaj yeem hloov kho rau ntau yam duab thiab qhov ntau thiab tsawg thiab sib xws nrog cov thev naus laus zis ntse teeb pom kev zoo, ua rau lawv muaj kev xaiv yooj ywm dua thiab yav tom ntej.
Xaus
Feem ntau, cov teeb incandescent thiab LED muaj qhov sib txawv tseem ceeb uas ua rau lawv haum rau ntau qhov xwm txheej thiab kev xav tau. Cov teeb incandescent muab lub teeb sov so, zoo li lub teeb ntuj, tab sis nws tsis siv hluav taws xob ntau thiab lub neej luv luv. Qhov sib txawv, cov teeb LED muab kev siv hluav taws xob zoo heev, lub neej ntev, thiab kev ywj pheej ntau hauv kev siv teeb pom kev niaj hnub.
Qhov kev xaiv ntawm cov teeb incandescent thiab LED nyob ntawm seb koj xav tau dab tsi, koj nyiam qhov zoo ntawm lub teeb, thiab koj xav txog tus nqi thiab ib puag ncig. Nrog rau kev nce qib ntawm thev naus laus zis, cov teeb LED zoo li yog qhov kev xaiv zoo tshaj plaws rau ntau tus neeg siv uas tab tom nrhiav kev daws teeb meem zoo, ruaj khov, thiab ruaj khov.
