LED lub teeb zoo zoo thiab teeb meem

Cov Peev Xwm Kev Sib Tham:

Txawm hais tias qhov teeb meem ntawm lub rooj loog LED tseem tseem ceeb tshaj peb lub sij hawm ntau tshaj qhov kev lag luam siab muaj zog, tiam sis cov kev siv hluav taws xob thiab kev siv nyiaj thiab lwm yam, siv 2 xyoos tom qab, LED teeb ci thiab siab siab sodium teeb yog yuav luag sib npaug tag nrho tus nqi. Yog li, nyob rau hauv qhov ntev khiav, LED vaj teeb teeb siv cov nqi yuav zoo tshaj qhov muaj siab siab sodium teeb. Piv nrog rau kev tawm siab, lub hwj huam ntawm lub siab muaj zog nanometer teeb yog kwv yees li 250 watts, LED tsuas 60 watts. Nyob rau hauv qhov kev pab cuam lub neej, lub siab siab sodium teeb yog kwv yees li ntawm 4,000 teev hauv nruab nrab, tab sis LED tau txog li 50,000 xuab moos Cov Nrog rau lub rooj sab laj cov teeb meem LED teeb txuas ntxiv, nws txoj kev sib txig sib tw yuav pib tshwm tuaj.

Siv cov lus zoo:

LED luminous efficiency yog siab. Mus yuav cov teeb pom kev zoo ntawm LED tau mus txog 100lm / W, nws qhov kev ua kom zoo dua li lub zog txuag hluav taws xob, cov teeb taws kub teeb thiab cov hluav taws xob teeb, txoj kev teeb pom kev zoo tshaj qhov siv hluav taws xob ntsaws ntsej muag feem ntau kuj siab tshaj 10%. Tau dhau los ua ib qhov luminous siab tshaj ntawm lub teeb ci. LED hloov cov roj teeb, lub teeb hluav taws xob, cov roj teeb uas muaj teeb meem thiab cov roj teeb siab thiab lwm lub teeb pom kev zoo tsis yog ib qho teeb meem loj ntawm kev teeb meem, tiam sis muaj teeb meem sij hawm.

kev sib tw:

Nrog LED teeb pom kev lag luam blowout rau hauv lub nroog, LED txoj kev teeb ua kom pom tseeb maj maj. Tag nrho cov lag luam muaj beachhead LED teeb rooj teeb meem lag luam tawm ntawm kev tswj xyuas. Txawm hais tias cov kev lag luam hauv cov lag luam hauv xyoo tas los no, txoj kev loj hlob sai, tab sis tseem tsis muaj cai tswj cov kev cai, uas ua rau tag nrho cov kev lag luam txawv ntawm ntau, ntawm ntau yam kev nce qib yog qhov tsis zoo. Nyob rau hauv kev nyuaj yog cov teeb pom kev zoo dua qub, qhov tsis muaj cov txheej txheem kev coj ua rau qhov teeb meem yog tshwj xeeb tshaj tawm. Muaj ntau tus neeg ua lag luam thiab cov neeg txhim kho, thiab tsis nkag siab txog kev tsim teeb meem ntawm cov teeb vaj tse, daim ntawv thov kev pabcuam tsis tuaj yeem qhia rau cov kev txwv. Piv txwv li, ntau lub lag luam thiaj li daws tau qhov teeb meem ntawm cov dej txias, qhov tsim ntawm "khoob" lub hwj huam. Tab sis rau lub teeb vaj teb, qhov no zoo "vaj tse" muaj nuj nqi yog tsis zoo, tsis haum rau teeb vaj teeb.

Txawm hais tias tsoomfwv txoj kev txhawb, LED vaj teeb teeb pom kev lag luam yog tsim sai, tab sis tsis tau ignored yog tias tiag tiag tau LED vaj teeb lub lag luam ntev lub sij hawm ntev tseem tabtom ntsib txoj kev nyuaj nyhav. Ntxiv rau lub siab, LED vaj teeb teeb khoom yog txojkev loj teeb meem xws li: lub teeb, cua sov thiab lub zog fais fab tuag.

Los ntawm qhov pom kev ntawm qhov pom kev, ntawm ib tes yog qhov yuav tsum tau txhim khu cov luminous efficiency ntawm LED, ntawm qhov tod tes yog los txhim kho lub teeb pom kev. Ib qhov loj ntawm lub khw LED teeb pom kev zoo khoom, LED teeb ci qhov teeb meem yog npaj los ntawm cov qauv ntoo, qhov loj tshaj ntawm qhov mus kom ze no yog txoj kev los daws qhov teeb meem kub, tab sis vim tias cov qauv no tsis txaus ntxig txoj hauv siab, ntau qhov loj, ua rau lub khob ntsuas tsis ncav lub ntsiab ntawm lub teeb, yuav tsum tau siv lub lens ob lub ntsiab muag kom tau txais kev ywj pheej uas tsis ywj siab, uas rau kev xaiv qhov kev lens xaiv dua, ntau cov ntaub ntawv, ob lo ntsiab muag ob leeg muaj teeb meem, cuam tshuam rau cov khoom Siv cov nyhuv. Thiab yog tias txoj kev kho mob tsis zoo, kev siv lo ntsiab muag kuj yuav cuam tshuam txog kev teeb pom kev thiab kev pom tseeb.

Yuav kom txhim kho cov teeb meem saum toj no, qee qhov teeb pom kev ua vaj tse LED tau siv cov txheej txheem siv teeb pom kev ntawm lub teeb pom kev zoo, lub hom teeb ci teeb kom txo tau cov qauv ntawm cov khoom siv vuam voog thiab cov khoom tiav thaum ua haujlwm vim lub teeb pom kev ntawm txoj kev lossis qee yam khoom qee yam hauv qab Qhov sib ntxiv, txij thaum siv cov khob ua kom lub zog nruab nrab ntawm lub teeb, tab sis kuj yuav tsum tsis txhob siv cov lens qib siab thiab qhov tsis zoo. Tab sis nws yog undeniable tias kev siv ntawm xws li ib pob ntawm lub teeb qhov chaw yuav fim ntau lub zog txias txias. Los ntawm lub hwj chim pom, sib txawv ntawm cov khoom siv txhuas teeb pom kev zoo tuaj yeem ncaj qha mus rau kev pauv hluav taws xob, LED yog lub cuab tam tsawg-voltage, thiab qhov kev xav tau rau qhov tsav tam sim no, uas yuav tsum tau LED qhov teeb ci zog tsim kom rov hloov . LED hwj chim nqi them rau li ntawm 10% ntawm tag nrho cov khoom muag -20%, hwj chim system, tab sis yuav cuam tshuam rau lub neej khoom rau ib qhov loj.

Daim ntawv thov nce qib tseem tabkaum qhov kev tsim ntawm LED vaj teeb vim li cas. Raws li cov teeb vaj tse LED tsis muaj cov qauv kev cai, xim kub, xim thiab qhov muag thiab ntau lwm yam loj tsis tau txiav txim siab, LED teeb teeb tsis tuaj yeem txhawb siab. Qhov thib ob, cov teeb vajtses LED yog cov nqi siab heev rau LED teeb los txhawb kev siv cov kev cov nyom loj. Coupled nrog LED rooj teeb rooj teeb pom kev zoo thiab kev siv ntawm lub vaj teeb vaj teeb kev kev pavement kev xeem qauv tsis tau tsim, ntawm no yog theem, LED txoj kev teeb ua lag luam teeb meem yog nyob ntawm tsoomfwv qhov kev txhawb zog.
