Nws paub zoo tias cov khoom lag luam los ntawm txhua lub tebchaws uas nkag mus rau hauv EU thiab EFTA yuav tsum tau dhau daim ntawv pov thawj CE thiab muab lub cim CE lo rau. Daim ntawv pov thawj CE ua haujlwm ua daim ntawv hla tebchaws rau cov khoom lag luam nkag mus rau hauv EU thiab EFTA kev lag luam. Niaj hnub no, Tianxiang, ib lub tuam txhab uas tau tsim cov khoom lag luam no.Tuam Tshoj chaw tsim khoom teeb pom kev zoo ntse LED txoj kev teeb pom kev zoo, yuav tham txog daim ntawv pov thawj CE nrog koj.
Daim ntawv pov thawj CE rau lub teeb LED muab cov lus qhia txog kev siv tshuab rau cov khoom lag luam los ntawm txhua lub tebchaws uas ua lag luam hauv kev lag luam European, ua kom cov txheej txheem kev lag luam yooj yim dua. Cov khoom lag luam los ntawm txhua lub tebchaws uas nkag mus rau EU thiab EFTA yuav tsum tau dhau daim ntawv pov thawj CE thiab muab lub cim CE lo rau. Daim ntawv pov thawj CE ua haujlwm ua daim ntawv hla tebchaws rau cov khoom lag luam nkag mus rau EU thiab EFTA kev lag luam. Daim ntawv pov thawj CE qhia tias cov khoom lag luam ua tau raws li cov kev cai nyab xeeb uas tau teev tseg hauv EU cov lus qhia. Nws sawv cev rau lub tuam txhab txoj kev cog lus rau cov neeg siv khoom, ua rau cov neeg siv khoom ntseeg siab ntxiv. Cov khoom lag luam uas muaj lub cim CE txo cov kev pheej hmoo cuam tshuam nrog kev muag khoom hauv kev lag luam European. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias daim ntawv pov thawj CE yuav tsum tau txais los ntawm Lub Koom Haum tau tso cai los ntawm EU.
Cov kev pheej hmoo no suav nrog:
Kev pheej hmoo ntawm kev raug kaw hauv kev lis kev cai thiab kev tshawb nrhiav;
Kev pheej hmoo ntawm kev tshawb nrhiav thiab kev rau txim los ntawm cov koom haum saib xyuas kev ua lag luam;
Kev pheej hmoo ntawm kev liam tawm tsam cov neeg sib tw rau lub hom phiaj sib tw.
Kev Ntsuas Daim Ntawv Pov Thawj CE rau Cov Teeb LED
Kev xeem daim ntawv pov thawj CE rau cov teeb LED (txhua lub teeb ua tau raws li cov qauv zoo ib yam) feem ntau suav nrog tsib qhov chaw hauv qab no: EMC (EN55015), EMC (EN61547), LVD (EN60598), thiab rau cov rectifiers, kev xeem LVD feem ntau suav nrog EN61347 thiab EN61000-3-2/-3 (kev xeem harmonic).
Daim ntawv pov thawj CE muaj EMC (Electromagnetic Compatibility) thiab LVD (Low Voltage Directive). EMC suav nrog EMI (kev cuam tshuam) thiab EMC (kev tiv thaiv kab mob). LVD, hauv cov lus yooj yim, sawv cev rau kev nyab xeeb. Feem ntau, cov khoom siv hluav taws xob qis nrog AC voltages qis dua 50V thiab DC voltages qis dua 75V zam los ntawm kev kuaj LVD. Cov khoom siv hluav taws xob qis tsuas yog xav tau kev kuaj EMC, ua rau muaj daim ntawv pov thawj CE-EMC. Cov khoom siv hluav taws xob siab xav tau ob qho tib si EMC thiab LVD kev kuaj, ua rau muaj ob daim ntawv pov thawj thiab cov ntawv qhia: CE-EMC thiab CE-LVD. EMC (Battery Compatibility) - EMC cov qauv xeem (EN55015, EN61547) suav nrog cov khoom xeem hauv qab no: 1. Kev Tawm Hluav Taws Xob 2. Kev Tawm Hluav Taws Xob 3. SD (Static Discharge) 4. CS (Conduction Immunity) 5. RS (Radiation Immunity) 6. EFT (Electromagnetic Field Effect) pulses.
LVD (Low Voltage Directive) - Cov qauv xeem LVD (EN60598) suav nrog cov khoom xeem hauv qab no: 1. Qhov Txhaum (Kev Ntsuas) 2. Kev Cuam Tshuam 3. Kev Co 4. Kev Poob Siab 5. Kev Tshem Tawm 6. Creepage 7. Kev Poob Siab Hluav Taws Xob 8. Kub 9. Kev Thauj Khoom Ntau Dhau 10. Kev Ntsuas Kub Siab.
Qhov tseem ceeb ntawm daim ntawv pov thawj CE
Daim ntawv pov thawj CE muab ib qho qauv sib koom ua ke rau txhua yam khoom nkag mus rau hauv kev lag luam European, ua kom yooj yim rau cov txheej txheem kev lag luam. Kev lo lub cim CE rau ntawm lub teeb LED ntse qhia tau tias cov khoom tau ua raws li cov kev cai nyab xeeb ntawm EU cov lus qhia; nws sawv cev rau lub tuam txhab txoj kev cog lus rau cov neeg siv khoom thiab ua kom cov neeg siv khoom ntseeg siab rau cov khoom. Kev lo lub cim CE txo qhov kev pheej hmoo ntawm kev muag khoom hauv Tebchaws Europe. TxhuaTianxiang ntse LED txoj kev teeb pom kev zootau ntawv pov thawj CE thiab ua raws li EU cov kev cai tseem ceeb rau kev sib raug zoo ntawm hluav taws xob (EMC) thiab Low Voltage Directive (LVD). Txij li kev nyab xeeb ntawm lub voj voog thiab kev tswj hwm hluav taws xob hluav taws xob mus rau kev ruaj khov ntawm kev ua haujlwm hluav taws xob, txhua yam tau txheeb xyuas los ntawm cov koom haum kuaj xyuas kev tshaj lij.
