Ua ntej, qhov teeb meem ntawm LED North American cov qauv
LED teeb txuag teeb raws li ib yam khoom tshiab, tam sim no North American khoom kev ruaj ntseg qauv tsis yog rau cov kev cai ntawm cov khoom lag luam, LED khoom kuaj tau los ua ib qho kev kawm ntawm kev lag luam. US UL laboratory rau qhov teeb meem tam sim no hauv qhov kev lag luam no, yog tsim kom muaj cov qauv siv hluav taws xob teeb txuag hluav taws xob txuag hluav taws xob qauv UL8750, cov qauv no tseem yog cov ntawv tseem ceeb, tsis yog raug cai raws li cov qauv ntawv pov thawj. Yog li ntawd, qhov teeb meem hluav taws xob teeb hluav taws xob teeb hluav taws xob teeb hluav taws xob teeb meem LED, tsis tau tag nrho daws.
Lub hauv paus ntsiab lus ntawm cov roj hluav taws xob txuag hluav taws xob yog los ntawm tus tes hloov qhov fais fab mov module yuav AC hwj huam hloov DC rau lub hwj huam khoom mus rau kev ua hauj lwm lub teeb pom kev zoo. Raws li cov hauv paus ntsiab lus thiab cov qauv ntawm cov hluav taws xob uas txuag hluav taws xob (energy saving saver), Lub Tebchaws Asmeskas MET laboratory tau npaj muaj cov txheej txheem cov kev xeem nyob rau theem no: kev siv cov cim hluav taws xob txuag cov qauv hauv Teb Chaws Asmeskas cov qauv ntawv pov thawj UL1993 (sib txawv hauv Canadian txheem CAN / CSA -C22.2No.0, YOG / CSA-C22.2No.74), thiab lub hwj chim module txuj UL1310 los yog UL1012 (sib haum rau Canadian txheem CAN / CSA-C22.2No.107) ntawm cov roj teeb txuag hluav taws xob rau kuaj thiab ntawv pov thawj.
Thib ob, nrhiav tau cov ntsiab lus tseem ceeb
Cov nram qab no raws li UL1993, UL1310 thiab UL1012 cov qauv, LED teeb txuag teeb ntawv pov thawj cov teeb meem tseem ceeb, ua ib co kev tsim kho.
1. M aterial
Cov roj teeb txuag hluav taws xob txeem tau ua rau ntau hom duab rau cov teeb pom kev zoo ntawm cov roj teeb hluav taws xob, piv txwv li, nws cov duab zoo li lub raj fais fab, fluorescent raj los ntawm cov ntawv tho polymer thiab lub teeb-emitting diode pob hauv sab hauv. Transparent polymer vaj tsev nyob rau hauv cov khoom ua si rau hluav taws kub thiab hluav taws xob ua haujlwm tsis zoo. Raws li cov qauv uas yuav tsum tau ua, cov khoom siv hluav taws xob txuag hluav taws xob yuav tsum ntau tshaj V-1, ces daim npog pob zeb polymer yuav tsum siv V-1 qib saum cov khoom.
Nws yuav tsum raug sau tseg tias cov khoom plhaub kom tiav cov qib V-1, lub thickness yuav tsum ntau dua los yog sib npaug rau qhov yuav tsum tau tuab ntawm cov khoom raw V-1, kev ntsuam xyuas hluav taws kub thiab thickness yuav tsum muaj nyob hauv cov khoom siv raw UL yellow card Lub Tiag tiag tiag pom tau tias cov tuam txhab tsim kom muaj lub ci ci teeb ntawm cov teeb ci, cov pob tshab polymer plhaub feem ntau ua nyias nyias, uas yuav tsum muaj cov neeg tsim khoom kom ntseeg tau tias cov khoom siv los xyuas kom meej tias cov khoom yuav tsum tau ua kom tiav cov qib kev tiv thaiv hluav taws thickness. Vim tias nyias cov ntaub ntawv raw nyias muaj nyias qhov sib txawv ntawm qhov kev ntsuas hluav taws, qee cov ntaub ntawv muaj peev xwm ua tau raws li qhov kev ntsuam xyuas hluav taws kub dua ntawm cov thicknesses. Cov lag luam muaj peev xwm xaiv tau cov khoom siv raw khoom los ua cov khoom plhaub.
2. Taug kev qis
Raws li cov khoom tsim cai, cov khoom siv los simulate qhov tseeb siv cov txheej txheem yuav tshwm sim rau lub caij nplooj zeeg ntawm qhov teeb meem no rau qhov kev xeem ntawv, qhov khoom ntawm 0.91 meters siab mus rau lub rooj tsav tsheb, lub plhaub khoom tsis tuaj yeem tawg thiab raug mus rau qhov chaw txaus ntshai. Thaum lub khw tsim cov khoom siv los ua cov khoom khauj khaum, nws yuav tsum xav txog qhov kev xav tau ntawm no.
3. Lub zog hluav taws xob
Lub vaj tsev pob tshab npog lub hwj huam hauv sab hauv, thiab cov khoom vaj khoom tsev yuav tsum muaj raws li qhov hluav taws xob muaj zog. Raws li tus qauv tsim nyog, raws li North American qhov hluav taws xob ntawm 120 volts, qhov siab nyob nrog qhov chaw nyob thiab lub plhaub (them nrog hlau foil kuaj), los tiv thaiv AC 1240 volts ntawm hluav taws xob kev xeem. Raws li ib txwm muaj, cov khoom plhaub ntawm 0.8 hli los yog li ntawd, koj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm txoj kev kuaj hluav taws xob.
Kub Khoom: teeb pom kev zoo rau cov ces kaum , Cov pa teeb ntawm lub teeb , cov teeb meem tsis muaj teeb meem , cov teeb meem tsis muaj teeb meem , Lub teeb ci teeb ci , Lub teeb nrig Aisle teeb ,
