Guangdong LED kev lag luam tso tawm tus nqi khaws cia kev loj hlob sai rau 4 xyoo sib law liag
Txij li xyoo 2010, tus nqi tso tawm ntawm Guangdong' s LED kev lag luam tau khaws kev loj hlob sai rau plaub xyoos sib law liag. Hauv xyoo 2013, nws tau mus txog 281 billion yuan, nce 7 npaug los ntawm 39 billion yuan hauv xyoo 2009, thiab nyob rau qib thib ib hauv lub xeev' yim qhov kev lag luam tsim tawm tshiab raws li kev loj hlob.
Tam sim no, muaj ntau dua 4,000 lub tuam txhab LED hauv xeev Guangdong, tsav ze li 3 lab txoj haujlwm ntsig txog. LED kev lag luam pawg nrog Shenzhen ua tus thawj coj thiab Zhongshan, Huizhou, Foshan, Jiangmen thiab Dongguan raws li Pearl River Delta industrial siv tau tsim, tsim tag nrho cov lag luam saw los ntawm cov khoom siv substrate, epitaxial wafers, chips, ntim rau daim ntawv thov. Ntawm lawv, muaj 25 lub tuam txhab LED teev npe, suav txog 60% ntawm tag nrho cov npe teev npe tuam txhab lag luam LED hauv tebchaws, nrog rau tag nrho cov nqi lag luam ze li ntawm 100 billion yuan.
Raws li qhov kawg ntawm 2013, Lub Nroog Guangdong tau muaj ze li ntawm 50,000 daim ntawv thov patent hauv cov haujlwm ntsig txog ntawm LED kev lag luam, suav txog kwv yees li 30% ntawm lub teb chaws LED daim ntawv thov patent. Nyob rau xyoo tas los no, tus lej ntawm cov thev naus laus zis nrog kev ywj pheej ntawm cov cuab yeej cuab tam txoj cai tau ua tiav cov txiaj ntsig tseem ceeb. Piv txwv li, Zhongke Hongwei thiab Zhaoxin Group tau ua tiav kev tsim kho hauv MOCVD tus qauv, kev ua haujlwm siab tshiab-lub zog loj LED chips raws li zinc oxide epitaxial pob tshab electrode qauv, thiab gallium nitride homoepitaxial thev naus laus zis tau ua tiav kev lag luam sib txawv.
Txij li xyoo 2010, LED kev lag luam hauv xeev Guangdong tau ua tiav txoj kev loj hlob sai, thiab tau qhia cov yam ntxwv ntawm kev nce qib kev lag luam, pom tseeb qhov zoo ntawm cov pawg ua lag luam, kev ua tiav hauv cov tub ntxhais thev naus laus zis, maj mam tsim cov txheej txheem, thiab cov txiaj ntsig zoo hauv kev nthuav dav thiab thov.
