Txheeb xyuas qhov xwm txheej ntawm kev lag luam teeb pom kev zoo
Ib, kev tsom xam yooj yim
Hauv keeb kwm ntawm tib neeg teeb pom kev zoo, Edison tau tsim lub teeb ci ntsa iab, uas txhais tau tias yog pib ntawm lub teeb pom kev zoo. Nrog rau kev txhim kho thev naus laus zis, kev tshwm sim ntawm cov teeb roj fluorescent tau ntsib ntau yam kev xav tau ntawm tib neeg teeb pom kev zoo. Tam sim no nws yog hmo ntuj thoob plaws ntiaj teb. Feem ntau ntawm cov teeb pom kev sab hauv tsev siv cov teeb roj fluorescent. Txawm li cas los xij, txawm hais tias cov teeb roj fluorescent muaj ntau qhov zoo, ib qho ntawm qhov tsis zoo tshaj plaws yog tias lawv siv hluav taws xob ntau heev. Feem ntau ntawm cov hluav taws xob hluav taws xob tau siv hluav taws xob. Ib qho ntxiv, cov tshuaj mercury hauv lub teeb muaj teeb meem ua paug rau ib puag ncig. Yog li ntawd, nrhiav lub teeb pom kev zoo tshiab. Cov teeb pom kev ib txwm yog txoj haujlwm ntawm cov kws tshawb fawb thiab cov lag luam. Txog rau thaum xyoo pua puas xyoo dhau los, kev tsim lub teeb ci-emitting diodes coj kaj ntug mus rau lub teeb pom kev yav tom ntej, thiab LEDs pib nkag mus rau teeb pom kev lag luam.
Piv nrog rau cov teeb pom kev ib txwm muaj (xws li cov teeb roj fluorescent thiab cov teeb roj teeb), thaum LEDs ze rau qhov kev hloov pauv theoretical, kev ua kom pom kev zoo ntawm LEDs yog 5-20 npaug ntau dua li ntawm cov teeb pom kev ib txwm muaj. Txawm hais tias nyob rau theem tam sim no ntawm kev tsim khoom ntau, qib kev ua kom pom kev zoo yog nyob nruab nrab ntawm 2-15 zaug. Nyob rau tib lub sijhawm, ua ke nrog qhov zoo ntawm nws kev coj ncaj, qhov sib txawv yuav ntau dua. Vim yog qhov hloov pauv hauv txoj cai ntawm kev tso lub teeb tawm, nws lub neej yuav nyob ntev dua li ntawm cov teeb pom kev ib txwm muaj. Ib qho ntxiv, vim tias LED muaj cov txiaj ntsig zoo xws li tsis muaj kev puas tsuaj rau kev noj qab haus huv thiab ib puag ncig, nws tau raug lees paub tias yog lub teeb pom kev zoo tshaj plaws rau lwm tiam nyob rau theem no.
Txawm li cas los xij, vim tias tus nqi siab ntawm LED teeb pom kev zoo, cov teeb pom kev ib txwm muaj (cov teeb roj teeb thiab cov teeb roj fluorescent) tseem yog cov khoom tseem ceeb hauv kev lag luam teeb pom kev zoo thoob ntiaj teb. Txij li xyoo 2008, lawv suav txog ze li 80% ntawm tag nrho cov lag luam teeb, thiab yuav muaj ntau ntxiv hauv xyoo 2011. Nrog ib feem ntawm ntau dua 50%, nws tseem muaj kev lag luam sib faib ze li 40% los ntawm 2015. Nws tuaj yeem pom tias cov roj teeb thiab cov roj fluorescent tseem tsis yooj yim los hloov pauv hauv kev lag luam teeb pom kev zoo nrog tus nqi qis. Ib qho ntxiv, kev txuag hluav taws xob teeb pom kev lag luam tau maj mam pib loj hlob tsis tu ncua tom qab xyoo 2008. Nws tau cia siab tias yuav nkag mus rau lub sijhawm siab tshaj hauv xyoo 2011. Lub sijhawm txij xyoo 2012 txog 2014 yog suav tias yog lub sijhawm nce rau kev loj hlob ntawm kev txuag hluav taws xob lub teeb qhov muag teeb nyob rau hauv kev lag luam teeb pom kev zoo. Thaum lub sijhawm teeb LED, nws txoj kev lag luam yuav maj mam nce.
Tam sim no, Tuam Tshoj' kev lag luam teeb pom kev zoo tseem muaj teeb meem ntawm kev lag luam qis. Los ntawm kev xav ntawm kev faib khoom hauv cheeb tsam, Tuam Tshoj cov tuam txhab kev lag luam teeb pom kev zoo feem ntau yog nyob hauv Pearl River Delta thiab Yangtze River Delta. Lawv tau tsim cov nplai loj ntawm cov peev txheej tsim khoom thiab muaj kev sib koom ua lag luam hauv tsev thiab txawv teb chaws, thiab lawv cov peev txheej tsim khoom tau nyob hauv lub tebchaws cov hluav taws xob teeb pom kev zoo thiab cov khoom lag luam teeb pom kev zoo. Ntau tshaj 70% ntawm nws tsis yog tsuas yog lub chaw nruab nrab ntawm Tuam Tshoj' kev lag luam teeb pom kev zoo, tab sis kuj yog lub hauv paus tseem ceeb ntawm cov teeb pom kev zoo hauv lub ntiaj teb. Ntawm lawv, cov tuam txhab teeb pom kev zoo hauv Pearl River Delta tau tsim kho thaum ntxov, ua rau kev txhim kho kev lag luam. Txawm li cas los xij, cov tuam txhab teeb pom kev zoo hauv Yangtze River Delta tau mob siab rau kev tswj hwm sab hauv thiab xa tawm muag ntawm lawv cov tuam txhab. Tsis yog lawv ua ntej ntawm Pearl River Delta hauv kev sib tw hauv kev lag luam hluav taws xob, tab sis lawv tseem qhia kev ua phem rau hauv kev lag luam teeb pom kev zoo. Kev teeb tsa kev lag luam txawv teb chaws zoo tshaj hauv lub tebchaws tseem coj kev sib tw muaj zog rau cov cuab yeej teeb pom kev zoo hauv tsev, thiab kev lag luam yuav rov txhim kho thiab koom ua ke ntxiv, thiab maj mam dhau los ua qhov tseem ceeb.
Kev lag luam qis qis ntawm kev lag luam teeb pom kev zoo tiag tiag qhia tau tias kev lag luam no tsis muaj pab pawg lag luam loj. Kev lag luam qis qis kuj tseem qhia txog qib qis ntawm cov npe khoom lag luam hauv kev lag luam thiab tsis muaj cov khoom lag luam sib tw. Txawm li cas los xij, ntau xyoo, cov tuam txhab teeb pom kev zoo thiab cov khoom siv hluav taws xob tau yeej lub npe khoom lag luam hauv tebchaws. Qee lub tuam txhab tau txais kev lees paub lub npe nrov npe hauv kev lag luam. Foshan Teeb pom kev zoo hu ua" Suav Teeb Vaj" ;, Huadong Technology tau paub tias yog tus naj npawb ib hom ntawm cov teeb roj fluorescent, Zhejiang Sunshine tau paub tias yog tus naj npawb ib hom ntawm lub teeb txuag hluav taws xob, thiab Ningbo Liaoyuan paub tias yog txoj kev teeb. Thawj lub npe, NVC paub tias yog thawj lub npe ntawm kev lag luam teeb pom kev zoo, Op paub tias yog thawj lub npe ntawm teeb pom kev hauv tsev, thiab Zhenmingli paub tias yog thawj lub npe ntawm LED teeb pom kev zoo. Txawm li cas los xij, kev muag khoom loj tshaj plaws hauv khw yog cov khoom siv teeb pom kev zoo thoob ntiaj teb xws li Philips thiab Osram. Ntxiv rau, Nyij Pooj' s Toshiba, Panasonic, Hong Kong Prosperity Lighting Equipment Co., thiab Taiwan' cov tuam txhab teeb pom kev zoo xws li Xiangyao, Qianli, Xingrui, Xilina, thiab lwm yam. hauv kev lag luam hauv tsev.
2. Patent cov ntaub ntawv ntawm kev lag luam teeb pom kev zoo
Los ntawm kev pom ntawm cov teeb pom kev zoo, daim ntawv thov patent thiab cov ntawv tshaj tawm qhia txog kev nce xyoo ib xyoos. Guangdong, Zhejiang thiab Taiwan muaj ntau daim ntawv thov patent, uas cov qauv siv hluav taws xob patents suav nrog tus lej loj.
Los ntawm kev pom ntawm daim ntawv thov patent thiab cov ntawv luam tawm ntau xyoo, txij li xyoo 1992, daim ntawv thov patent thiab tshaj tawm ntawm cov teeb pom kev zoo tau pom qhov nce zuj zus, tshwj xeeb yog tom qab xyoo 2000, kev loj hlob tau nce zuj zus.
Los ntawm kev xav ntawm kev faib khoom ntawm patents los ntawm lub tebchaws thiab xeev, thaj chaw uas muaj kev faib ntau tshaj ntawm cov teeb pom kev zoo teeb pom kev zoo yog Guangdong, Zhejiang thiab Taiwan. Tsis tas li ntawd, Jiangsu, Shanghai, Beijing, Nyiv, Shandong, Fujian thiab Liaoning kuj muaj ntau daim ntawv pov thawj.
Teeb pom kev zoo patent hom
Los ntawm kev xav ntawm cov qauv patent ntawm cov teeb pom kev zoo, cov qauv siv hluav taws xob patents suav nrog qhov loj dua, ua raws li kev tsim qauv patents, thiab cov ntawv pom zoo patents yog qhov me me.
