Puas yog LED teeb tiag tiag qis dua li cov teeb fluorescent zoo tib yam?

Puas yog LED teeb tiag tiag qis dua li cov teeb fluorescent zoo tib yam? Puas yog LED teeb tiag tiag qis dua li cov teeb fluorescent zoo tib yam? Yog tias koj muab piv rau lawv, koj yuav pom tias nws yog kev nkag siab yuam kev. Yog tias cov teeb ci LED tsis zoo rau cov teeb pom kev zoo tib yam, ces tsis tas yuav tsim cov teeb ci LED. Cov txiaj ntsig muaj ntau, yog tias koj tsis ntseeg kuv, koj txuas ntxiv saib

Kuv tau tshawb xyuas qee cov ntaub ntawv hauv Is Taws Nem, thiab qee tus neeg hais tias LED teeb yeej tsis zoo li cov teeb fluorescent zoo tib yam. Puas yog LED teeb tsim nyog rau kev siv hauv tsev?

Nqe Lus Nug 1. Lub teeb kev taw qhia muaj zog heev, tsis haum rau cov teeb pom kev nyab xeeb?

Nqe Lus Nug 2: Cov kev xav tau ntawm lub tshuab hluav taws xob thiab cov cua txias yog siab, thiab cov khoom siv hauv tsev hauv cheeb tsam no tsis tuaj yeem txheeb xyuas tau. Vim tias qhov tam sim no yuav tsum tau ua, lub tshuab hluav taws xob tswj nti yuav kim heev.

Nqe Lus Nug 3. Lub 50,000-teev lub neej ntawm LED teeb hauv Suav teb yog qhov tsis muaj tseeb. 50,000 teev tsuas yog lub neej ntawm LED diodes, thaum lub neej ntawm cov khoom siv hluav taws xob zoo tib yam tsuas yog 8,000 teev. LED teeb ua haujlwm li cas rau 50,000 teev?

Nqe Lus Nug 4. Qhov kub thiab txias heev muaj qhov cuam tshuam zoo rau cov teeb ci LED, uas yuav ua rau lub teeb lwj, yog li qhov yuav tsum tau ua rau cov cua kub dissipation modules siab heev.

Nqe Lus Nug 5. Lub CRI ntawm cov xim rendering tus nqi ntawm LED lub teeb yog tsawg heev, thiab cov nyhuv ntawm kev siv nyob rau hauv lub tsev teeb pom kev zoo yog tsis zoo.

Teb cov lus hauv qab no:

Ua ntej, kev tsim kho qhov muag zoo tuaj yeem daws tau. Cov raj LED uas tsim los ntawm cov chaw tsim khoom muaj lub luag haujlwm yuav luag tsis paub qhov txawv ntawm cov raj fluorescent. Ntxiv mus, lub raj LED tso tawm lub teeb ntawm ib nrab ntawm nws, qhov kev siv lub teeb yog siab, thiab lub teeb fluorescent pov tseg 40-50 feem pua.

Ob, koj tau txais yam koj them rau. Cov ntawv pov thawj CQC hauv tsev tseem tseem nruj heev ntawm cov qauv tsim thiab kev siv. 6063 txhuas cov khoom siv rau cov cua sov dissipation, uas yog, cov khoom siv txhuas rau sab nrauv.

Thib peb, lub neej theoretical ntawm LED diodes yog ntev heev. Coj mus rau hauv tus account lub teeb lwj (LED's luminous efficiency poob lub sij hawm). Lub neej feem ntau cuam tshuam nrog cov khoom siv hluav taws xob. Lub hwj chim mov muaj feem xyuam rau lub neej ntawm electrolytic capacitor. Lub neej feem ntau yog hais txog cov ntaub ntawv ntawm 105 degrees, thiab thaum lub hwj chim mov ua hauj lwm ib txwm, qhov kub yog tswj hauv qab no 85 degrees. Raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ua haujlwm ob npaug thaum qhov kub thiab txias poob los ntawm 10 degrees Celsius, 105 degrees sib haum rau 12,000 teev, 95 sib raug rau 24,000, 85 sib raug rau 48,{{11} }}, thiab 50,{13}} teev ntawm lub neej qis dua 85 degrees tsis yog tus qauv cuav. Ntxiv mus, lub electrolytic capacitor yuav tsis poob ncaj qha thaum kawg ntawm nws lub neej, tab sis lub capacitance yuav poob mus rau 80 feem pua ​​ntawm cov nqi pib. 50,{17}} teev ntawm LED teeb tuaj yeem siv tau ntev dua, tsis muaj teeb meem. Nws kuj raug sim los ntawm kev ua lag luam.

Plaub, lub raj LED tsis tu ncua tau daws qhov teeb meem ntawm cov cua sov dissipation, ntawm chav kawm, nws nyob ntawm seb koj txaus siab siv cov khoom ntawm tus nqi twg. Nws yog twv yuav raug hu tsis muaj teeb meem mus yuav aluminium-yas raj coj teeb. Kev ntshaw pheej yig, yuav iav, cov kav dej yas, ces yuav muaj teeb meem.

5. Ordinary fluorescent teeb CRI75 txaus. LED raj muaj nyob rau ntawm 70 mus rau 95. Lub teeb txuag hluav taws xob feem ntau yog nyob rau hauv thaj tsam ntawm 65 mus rau 90, thiab cov raj ncaj fluorescent teeb, uas yog siv dav siv iav fluorescent teeb, feem ntau yog nyob rau hauv thaj tsam ntawm 70, 80 txog 95. Cov xim rendering Performance index ntawm LED raj yog qhov siab, uas tuaj yeem ua tau raws li qhov xav tau ntawm lub teeb pom kev zoo, lub neej ntawm lub teeb hlaws nti tuaj yeem ntev heev, thiab xim rendering Performance index tuaj yeem kho raws li qhov xav tau, uas yog hloov tau ntau dua.

Lub luminous efficiency ntawm LED raj feem ntau yog 85-100LM / W, qee qhov yog 130lm / w, thiab qhov kawg siab tshaj plaws yog 200lm / w, tab sis tus nqi kim me ntsis. Qhov zoo dua yog tias nws tuaj yeem ua raws li qhov xav tau.

Cov ntsiab lus: LED hnub teeb tsis muaj qhov zoo dua li cov teeb fluorescent zoo tib yam. Lo lus nug yog koj xaiv li cas. Tsis txhob greedy rau pheej yig. Xaiv cov khoom lag luam niaj hnub, koj tuaj yeem siv nrog kev ntseeg siab. Tam sim no, ntau tus neeg siv tsis paub ntau txog kev siv tiag tiag ntawm LED teeb, yog li lawv yuav tsum xyuas cov ntaub ntawv tseem ceeb. Tsis txhob dag dag dag pej xeem. Nws yog qhov tsis lees paub tias vim qee cov tuam txhab ua lag luam tsis zoo tsim cov teeb ci LED tsis zoo, qhov tsis zoo, cov kev xav tau tsis tau ntsib, thiab lub neej tseem luv heev, uas ua rau cov duab zoo nkauj ntawm LED teeb thiab cuam tshuam rau cov neeg siv khoom xav tau. yuav. Qhov no yog qhov txawv txav. Qhov tshwm sim, kev ua lag luam yuav tsum ua kom muaj kev sib tsoo ntawm cov khoom cuav thiab cov khoom tsis zoo, cia cov khoom tsim nyog tau nrov, thiab muab kev ncaj ncees rau cov teeb pom kev zoo ntawm LED.

Puas yog LED teeb tiag tiag qis dua li cov teeb fluorescent zoo tib yam? Cia peb saib lub hauv paus ntsiab lus ntawm lub teeb emission.

Ua ntej, lub hauv paus ntsiab lus ua haujlwm ntawm lub teeb fluorescent

Thaum lub filament yog rhuab, ib tug loj tus naj npawb ntawm electrons yog emissions los ntawm lub low-potential kawg mus rau high-potential kawg ntawm ib tug zoo ceev nyob rau hauv qhov kev txiav txim ntawm high voltage ntawm ob hnub ntawm lub teeb raj. Nyob rau hauv tus txheej txheem ntawm kev nrawm nrawm, cov roj argon roj molecules hauv cov raj sib tsoo yog ionized sai. Lub ionization ntawm argon generates tshav kub, thiab lub tshav kub ua rau mercury ua vapor, uas yog ces ionized thiab emits muaj zog ultraviolet rays. Nyob rau hauv lub excitation ntawm ultraviolet lub teeb, phosphor nyob rau hauv lub raj phab ntsa emits yuav luag dawb pom lub teeb. Thaum lub teeb fluorescent zoo li qub, tsuas yog qhov qis tam sim no tso cai rau dhau los ntawm ob qhov kawg ntawm lub teeb, yog li qhov hluav taws xob siv rau lub teeb yog me ntsis qis dua lub zog hluav taws xob, tab sis qhov hluav taws xob siab dua yuav tsum tau tawg thaum lub teeb pom kev zoo. Lub teeb fluorescent pib ua haujlwm, yog li lub ballast ntxiv rau hauv Circuit Court. Lub rectifier tuaj yeem tsis tsuas yog tsim kom muaj qhov hluav taws xob ntau dua thaum pib, tab sis kuj ua kom ruaj khov tam sim no thaum lub teeb fluorescent ua haujlwm.

Thib ob, lub hauv paus ntsiab lus ua haujlwm ntawm LED teeb

Lub hauv paus ntsiab lus yog siv LED semiconductor chips los tawm lub teeb, thiab cov qauv yog qhov nyuaj dua li cov teeb fluorescent. Muaj cov plhaub ntxiv rau cov teeb pom kev zoo ntxiv rau cov tsav tsheb fais fab, thiab cov khoom siv hluav taws xob xws li ballasts tsis xav tau lawm.

Cov txheej txheem ua haujlwm yog tias LED qhov tam sim no tsis tu ncua hloov pauv qhov hluav taws xob siab 220v, kho thiab lim nws mus rau hauv DC voltage ua haujlwm, qhov tam sim no tsis tu ncua, thiab muab cov hlaws dai rau ntawm lub teeb ci LED kom nws ua haujlwm raws li qhov ntsuas tam sim no. . Thiab cov cai. Yog li ntawd, hom teeb no ruaj khov, yuav tsis muaj AC stroboscopic, lub zog hloov pauv siab li 90 feem pua, thiab nws muaj cov yam ntxwv ntawm kev tsim hluav taws xob tsawg, kev ua haujlwm siab luminous, lub neej ntev, kev tiv thaiv ib puag ncig, txuag hluav taws xob, thiab lwm yam. Nws qhov zoo yog ntau dua li cov teeb fluorescent.

Nws tuaj yeem pom tau tias lub teeb fluorescent thiab LED teeb muaj cov qauv sib txawv ntawm lub teeb pom kev zoo, ua rau muaj kev sib txawv ntawm lub neej thiab cov nqi sib txawv. Muab piv rau ntau yam, nws tuaj yeem pom tias cov txiaj ntsig tau pom tseeb.

Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri-pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag, LED chaw ntau pob teeb , LED High Bay, LED Classing Room Teeb, Yog tias koj xav yuav cov khoom lag luam zoo LED teeb pom kev zoo lossis muaj kev nkag siab ntau ntxiv ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov hu rau peb nug.
