Dab tsi yog qhov txawv ntawm LED teeb thiab lub zog-txuag teeb_Cov roj teeb puas txuag hluav taws xob ntau dua li lub zog- txuag teeb?
1. LED teeb
LED teeb, lub teeb -emitting diodes raug xa mus ua LEDs. Diodes ua los ntawm cov tebchaw uas muaj gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), thiab lwm yam tuaj yeem tawg lub teeb pom kev thaum cov hluav taws xob thiab qhov sib xyaw ua ke, yog li lawv tuaj yeem siv los ua lub teeb - emitting diodes. Siv raws li qhov taw qhia teeb hauv circuits thiab cov twj paj nruag, los yog tsim los ntawm cov ntawv nyeem lossis cov duab digital. Gallium arsenide diodes emit liab teeb, gallium phosphide diodes emit ntsuab teeb, silicon carbide diodes emit daj teeb, thiab gallium nitride diodes emit xiav lub teeb. Vim yog cov khoom siv tshuaj lom neeg, nws tuaj yeem muab faib ua cov organic teeb emitting diode OLED thiab inorganic teeb emitting diode LED.
Dab tsi yog qhov zoo ntawm LED teeb:
1. Kev txuag hluav taws xob, kev siv hluav taws xob ntawm cov LEDs dawb tsuas yog 1/10 ntawm cov teeb ci thiab 1/4 ntawm lub zog- txuag teeb;
2. Lub neej ntev, lub neej ntev tuaj yeem ncav cuag ntau dua 100, 000 teev, uas tuaj yeem piav qhia "ib zaug thiab rau tag nrho" rau cov teeb pom kev zoo hauv tsev;
3. Nws tuaj yeem ua haujlwm ntawm kev kub ceev. Yog hais tias lub zog - txuag cov teeb ntau zaus pib los yog muab tua, cov filament yuav tig dub thiab sai sai;
Dab tsi yog qhov tsis zoo ntawm LED teeb:
Tus nqi pib siab, tsis muaj kev ua haujlwm siab ntawm - lub zog LED, qhov tsav tam sim no tsis tu ncua (yuav tsum muaj lub zog tsav hluav taws xob). Nyob rau hauv sib piv, txhua yam ntawm cov tsoos teeb pom kev zoo muaj tej yam drawbacks.
Thib ob, lub zog- txuag teeb
Zog-txuag teeb, tseem hu ua lub zog- txuag qhov muag teev, lub teeb hluav taws xob hluav taws xob, cov teeb fluorescent compact thiab cov teeb fluorescent integrated, xa mus rau cov khoom siv teeb pom kev zoo uas sib txuas cov teeb fluorescent thiab ballasts (ballasts) rau hauv tag nrho. . Xyoo 2008, lub xeev tau tshaj tawm txoj haujlwm "teeb pom kev ntsuab", thiab cov neeg nyob hauv nroog thiab cov neeg nyob deb nroog thiab cov lag luam tau txais ib feem pua ntawm cov nyiaj pab rau kev siv lub zog - txuag teeb ntawm cov lag luam uas yeej. Kev nce qib ntawm lub zog- txuag teeb yog qhov tseem ceeb heev, txawm li cas los xij, ib puag ncig muaj kev phom sij ntawm kev siv hluav taws xob pov tseg-cov teeb txuag hluav taws xob kuj tau nyiam. Thaum kawg ntawm Lub Kaum Hli 2012, ntau pua lab lub zog-cov teeb txuag tau raug muab pov tseg los ntawm lub zog-txuag kev txhawb nqa, txhua qhov tuaj yeem ua paug rau 180 tons ntawm dej thiab av. Kev pov tseg thiab rov ua dua tshiab ntawm lub zog pov tseg- txuag teeb tau nyiam. Txawm li cas los xij, tib neeg qhov kev thov rau lub zog- txuag teeb tseem nce ntxiv, tshwj xeeb tshaj yog xyoo 2014, uas nyuam qhuav tuaj txog, thiab qhov kev thov tseem nce ntxiv.
Dab tsi yog qhov zoo ntawm lub zog- txuag teeb:
1. Compact qauv thiab me me.
2. High luminous efficiency ntawm 60Lm / w, lub zog txuag ntau tshaj 80 feem pua, txuag hluav taws xob.
3. tuaj yeem hloov qhov muag teev ncaj qha.
4. Lub neej ntev, 6 mus rau 10 npaug ntev dua li cov teeb ci.
5. Sab hauv phab ntsa ntawm lub teeb lub raj yog coated nrog ib tug tiv thaiv zaj duab xis thiab kev siv ntawm triple kauv filaments yuav ua tau zoo heev rau kev pab cuam lub neej.
Dab tsi yog qhov tsis zoo ntawm lub zog- txuag teeb:
1. Muaj cov pa phem mercury hauv cov txheej txheem tsim khoom thiab tom qab siv thiab pov tseg. Tam sim no, cov tebchaws sab hnub poob tseem ceeb heev rau cov pa phem mercury. Cov neeg Suav kuj paub ntau dua thiab paub txog kev puas tsuaj ntawm cov pa phem mercury
2. Vim nws yog cov khoom siv iav, nws yooj yim tawg, tsis yooj yim rau kev thauj mus los, thiab tsis yooj yim rau nruab
3. Nws lub hwj chim noj tseem loj heev
4. Yooj yim rau kev puas tsuaj, luv lifespan, txuag hluav taws xob tab sis tsis txuag nyiaj yog qhov zoo tshaj plaws portrayal ntawm nws.
Dab tsi yog qhov txawv ntawm LED teeb thiab lub zog - txuag teeb
Lub zog- txuag lub teeb yog lub ntsiab lus ntawm CFL (Compact Fluorescent Lamp), uas yog lub zog tseem ceeb -txuag piv nrog lub teeb ci qub.
LED qhov muag teev hais txog qhov muag teev uas siv LEDs ua lub teeb pom kev zoo, thiab lawv cov teeb pom kev zoo kuj yog siab heev. Lawv yog hom tshiab tam sim no thiab muaj kev nyiam los hloov CFLs. Nyob rau hauv xyoo tas los no, qee lub teeb pom kev zoo kuj tseem pom cov teeb ci LED.
Tam sim no, lub teeb pom kev zoo ntawm ob yog qis dua li ntawm CFL, thiab lub teeb pom kev zoo ntawm CFL yog 50-65lm / W. Lub luminous efficiency ntawm LED nws tus kheej yog siab heev, feem ntau yog tam sim no ntawm 100-130lm / W, tab sis vim lub teeb pom kev zoo ntawm lub LED thiab lwm yam teeb meem, lub luminous efficiency ntawm tag nrho cov teeb yog hais txog 65-80lm / W. , thiab qhov sib txawv ntawm ob yog tsis loj heev. , tab sis tus nqi ntawm CFL thiab LED nrog tib lub luminous flux feem ntau yog li ntawm 2-4 npaug ntau dua, tus nqi sib txawv yog tsawg dua thaum lub zog me me, thiab qhov sib txawv loj thaum lub zog loj. Lub nominal lifespan yog 6000-12000h, thiab nominal lifespan ntawm LEDs yog 10000-20000h. Cov kev sib piv no tsuas yog rau qee cov khoom xa tawm mus rau European Union lossis North America. Vim qhov tsis sib xws ntawm kev muag khoom hauv tsev, nws tsis tuaj yeem ua qhov kev ntsuam xyuas ntxaws. Txawm li cas los xij, qhov zoo tshaj plaws lifespan feem ntau yog hais txog kev xa tawm mus rau cov cheeb tsam no (xws li lub npe hu ua thoob ntiaj teb philips, osram, thiab lwm yam).
Raws li qhov teeb meem ntawm kev puas tsuaj rau lub zeem muag, qhov muag pom kev zoo dua li CFLs, thiab CFLs zoo dua li LEDs. Tshwj xeeb, feem ntau ntawm cov teeb ci LED tam sim no muag hauv Suav teb tsis them nyiaj rau qhov cuam tshuam ntawm LEDs ntawm lub zeem muag, thiab txhob txwm ua kom txo qis kev ua haujlwm ntawm lub teeb pom kev zoo ntawm LED teeb thiab tag nrho lub teeb, kom tag nrho lub teeb muaj lub teeb ci dua. efficiency. Rau cov ntaub ntawv xws li luminous flux, ib qho -theem PFC Circuit Court (nrog siab ripple thiab yooj yim eyetrain) yog siv los ua kom tau raws li kuv lub teb chaws thawj - qauv qauv rau cov teeb thiab cov nqi ntawm cov kwj kawg.
Puas yog LED teeb muaj zog dua li lub zog- txuag teeb?
Ua ntej tshaj plaws, nws yuav tsum tau hais meej tias LED qhov muag teev txuag hluav taws xob ntau dua li lub zog - txuag teeb. Cov neeg feem coob paub lossis tau hnov txog nws, tab sis ntau tus neeg tseem muaj kev tsis ntseeg txog nws. Tom qab tag nrho, lawv tsis tau xam qhov twg cov hluav taws xob tau txais kev cawmdim. .
Vim lub teeb sib txawv -emitting cov ntsiab cai ntawm lub zog- txuag teeb thiab LEDs, lawv luminous efficiency txawv. Lub luminous efficiency ntawm halogen hmoov zog- txuag lub teeb tsuas yog 30-40lm/W, thiab lub luminous efficiency ntawm peb-xim zog- txuag teeb yog siab dua qhov ntawd ntawm halogen hmoov zog- txuag teeb, txog 40. -60lm/W (cov khoom lag luam sib txawv muaj qhov sib txawv zoo thiab sib txawv luminous efficiency, Philips lub zog{15}} txuag teeb pom kev zoo yog li 60lm / W). Txawm li cas los xij, qhov ua tau zoo ntawm LED yog ntau dua li ntawm lub zog - txuag teeb, thiab qib kev tshaj lij tam sim no feem ntau mus txog 90-100lm / W. Yog li ntawd, hauv qhov tseem ceeb, qhov ci ntsa iab tsim los ntawm 1W LED xav tau tsawg kawg yog 2W lub zog-txuag teeb kom ua tiav qhov ci zoo sib xws. Txawm li cas los xij, qhov tseeb ci ntsa iab cuam tshuam los ntawm ntau yam. Qhov ncaj qha tshaj plaws yog qhov kub thiab txias. Lub teeb lwj, lub teeb txuag hluav taws xob yuav ua rau lub teeb ci ntsa iab, thiab LED yog lub teeb ci txias, qhov hluav taws xob tsim hluav taws xob tsawg dua li lub teeb txuag hluav taws xob, yog li LED lub teeb tawg me dua lub teeb txuag hluav taws xob;
Tseem muaj ntau tus neeg yuav khoom. Cov neeg siv paub tias LED yog lub zog ntau dua -txuag tshaj li lub zog- txuag teeb, tab sis lawv xav tias tus nqi ntawm LED yog kim dua li ntawm lub zog- txuag teeb. ntawm lub zog- txuag teeb. Los ntawm kev txheeb xyuas cov ntaub ntawv, tus nqi hluav taws xob siv nyob rau hauv cov txheej txheem ntawm kev siv lub zog- txuag teeb ntau tshaj qhov nyiaj txuag thaum yuav lub zog- txuag teeb. Yog li ntawd, nws raug nquahu kom koj siv LED teeb ntau li ntau tau, tshwj xeeb tshaj yog rau cov neeg siv khoom lag luam uas siv ntau ntawm lawv.
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 Stadium 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 ntau yam hauv - kev nkag siab tob ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov tiv tauj xa peb nug.
