3 qhov laj thawj tseem ceeb rau kev txhim kho qeeb ntawm LED kev lag luam teeb pom kev zoo
Kev tsim kho ntawm LED kev lag luam teeb pom kev zoo tsis tau ua kom yooj yim. Tag nrho LED kev lag luam tau raug dej nyab nrog&"nqe kev ua tsov rog &";&"tus tswv khiav tawm ntawm txoj kev &";&"cov khoom cuav thiab cov khoom phem &" ;, thiab" ua tsis tiav LED teeb pom kev tshuaj ntsuam" ;. Raws li kev tshuaj xyuas, kev txhim kho ntawm LED kev lag luam teeb pom kev lag luam qeeb. Qhov laj thawj tseem ceeb.
1. Muaj ntau lub tuam txhab lag luam, thiab nws nyuaj rau cov lag luam me thiab nruab nrab kom tau txais nyiaj txiag.
Xyoo 2014, muaj txog 20,000 lub tuam txhab hauv kev lag luam teeb pom kev zoo hauv tsev. Nrog rau kev txhim kho ntawm LED kev lag luam, ntau lub tuam txhab hauv lwm qhov kev lag luam kuj tau pib nkag mus rau hauv LED kev lag luam, ua rau muaj kev ua haujlwm hnyav dhau thiab ua rau kev lag luam poob qis ib puag ncig. Kev nqis peev ntau dhau ua rau LED kev lag luam hla dhau, thiab ntau lub tuam txhab nyob hauv nruab nrab thiab qis dua ntawm cov teeb meem kev lag luam qis dua. Overcapacity tau ua rau muaj kev sib ntaus sib tua tsis zoo ntawm cov tuam txhab, uas tau ua rau tus nqi ntawm cov tuam txhab nqes hauv cov lag luam LED txuas ntxiv poob qis, thiab lawv cov paj tau paj tau qis. Tam sim no, cov nyiaj tau los tag nrho ntawm LED kev lag luam tsuas yog ib puag ncig 20%, thiab cov nyiaj tau los tsawg dua 5%. Nws tseem yog qhov tsis txaus ntseeg qhov tseeb tias SMEs muaj teeb meem nyiaj txiag. Kev nce nqi sab nraud tau thawb qhov kev thov nyiaj. Yog tias tsis muaj peev nyiaj txaus, cov lag luam me thiab nruab nrab muaj kev nkag tau yooj yim rau cov peev txheej peev txheej, thiab qib kev txaus siab ntawm kev xav tau nyiaj txiag tsawg. Ua ke nrog lub hauv paus tsis muaj zog ntawm cov lag luam me thiab nruab nrab, qhov nyuaj ntawm kev tau txais qiv nyiaj kuj tau nce ntxiv. Txawm hais tias tau txais cov nyiaj qiv, cov paj laum tau nce thiab qhov lav tau siab heev, uas ua rau SMEs tsis tuaj yeem them taus.
2. Lub homogeneity ntawm cov khoom yog qhov hnyav, thiab qhov ua tau zoo tsis sib xws.
Tam sim no homogenization ntawm cov khoom lag luam LED yog dej nyab, thiab nws tau tsom mus rau qhov qis kawg. Qhov muab tso rau ntawm yam khoom no nws tus kheej qis, thiab nws tsis xav tau cov qauv tsim tshwj xeeb thiab lub teeb pom kev zoo kawg. Qhov txiaj ntsig nkaus xwb yog tus nqi qis dua, uas ua rau pom kev dav dav xav tau ntawm cov neeg siv khoom ib txwm muaj. Ib qho ntxiv, vim yog qhov kev lag luam qis, teeb tuaj yeem tso rau hauv kev ua lag luam tom qab&"sib sau ua ke &";
Xyoo 2014, cov chaw saib xyuas kev ua haujlwm tau zoo thoob plaws lub tebchaws tau tshaj tawm cov txiaj ntsig ntawm kev txheeb xyuas qhov chaw ntawm LED teeb pom kev zoo thiab lub teeb pom kev zoo tswj. Ntawm lawv, cov xwm txheej tsis tsim nyog tshwm sim nyob rau ntau qhov chaw, thiab qee qhov khoom tsis tsim nyog LED tau ua rau dej nyab hauv khw. Txhawm rau txhawm rau sib tw rau kev ua lag luam, cov tuam txhab siv cov khoom lag luam qis thiab ua haujlwm kom txo nqi. Cov khoom yog pheej yig thiab zoo tsis tau lav. Qhov no tau coj ncaj qha mus rau qhov tshwm sim ntawm cov khoom lag luam tsis zoo thiab tus nqi tsis meej pem hauv tag nrho LED kev lag luam kev lag luam.
3. Cov qauv yog qhov xav tau kev txhim kho sai, thiab cov cai tseem ceeb ntawm cov cuab yeej cuab tam txoj cai tsis muaj.
LED kev lag luam xav tau cov qauv txhawm rau koom ua lag luam, tab sis tam sim no kuv lub tebchaws tab tom ntsib teeb meem xws li lub suab txheej txheem, kev ua haujlwm tsis txaus, thiab hloov kho tsis raws sijhawm. kuv lub tebchaws' s cov qauv LED tau sib cais thiab ib leeg, feem ntau tsom mus rau kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom. Tsis muaj cov qauv rau kev lag luam ntws LED chips, ntim khoom, thiab thev naus laus zis los hais txog. Nyob rau tib lub sijhawm, cov qauv tam sim no npog tsawg dua cov hom khoom lag luam nqes peev. Kev tsim qauv ntawm cov qauv hauv ntau thaj tsam tsis sib luag, thiab muaj qhov tshwm sim ntawm kev sib tshooj, sib tshooj, thiab txawm tias tsis sib xws. Feem ntau ntawm cov qauv LED tau pom zoo ua qauv, tsis tas yuav tsum ua, uas ua rau qee lub tuam txhab' tsis ua tib zoo mloog cov qauv thiab nws nyuaj rau siv lawv. Nyob rau tib lub sijhawm, nrog kev txhim kho sai ntawm LED thev naus laus zis, qee qhov teeb pom kev zoo tsis tuaj yeem hloov kho rau cov thev naus laus zis tam sim no.
tam sim no kuv lub tebchaws tau dhau los ua lub ntiaj teb' tus tsim khoom lag luam loj tshaj plaws thiab xa tawm cov khoom lag luam teeb pom kev zoo, tab sis tsis muaj kev ywj pheej ntawm cov cuab yeej cuab tam txoj cai, tsis muaj zog ua lag luam patent paub, kev tiv thaiv yog qhov tseem ceeb hauv lub xeev tiv thaiv, thiab cov cuab yeej cuab tam teeb meem tseem ceeb. Raws li xyoo 2014, muaj kwv yees li 340,000 tus tswv cuab muaj tswv yim patents hauv ntiaj teb LED teb, suav nrog ntau dua 70,000 daim ntawv thov patent hauv Suav teb. Txawm li cas los xij, 70% ntawm txhua daim ntawv thov patent hauv Suav teb tau nyob hauv daim ntawv thov nqes hav ntawm cov khoom lag luam, thiab ntau dua li ib nrab ntawm cov tub ntxhais kawm ntawv patented thev naus laus zis tau nyob los ntawm ob peb lub tuam txhab thoob ntiaj teb. Hais txog hom kev thov daim ntawv thov patent, daim ntawv thov siv daim ntawv thov patent suav nrog qhov feem ntau ntawm 43.55%, tsim daim ntawv thov patent suav txog 31.11%, thiab cov ntawv thov patent tsim muaj tsuas yog 25.34%. Qhov tsis muaj qhov tseem ceeb patents thiab kev tsim qauv patents tau dhau los ua qhov txwv tsis pub txwv Suav tuam txhab LED los ntawm kev tawm mus.
Cov ntsiab lus: Muaj ntau lub tuam txhab, thiab nws nyuaj rau cov lag luam me thiab nruab nrab kom tau txais nyiaj txiag; homogeneity ntawm cov khoom yog qhov hnyav, thiab qhov tsis zoo yog qhov tsis sib xws; cov qauv yuav tsum tau txhim kho sai, thiab cov cai tseem ceeb ntawm cov cuab yeej cuab tam txoj cai tsis muaj. Qhov no tau ua rau kev txhim kho qeeb ntawm LED kev lag luam teeb pom kev zoo, thiab kev txhim kho sai thiab noj qab haus huv ntawm kev lag luam LED. Cov teeb meem no yuav tsis ua haujlwm tshwj tsis yog lawv raug daws.
