Yuav Ua Li Cas Ua Tau Zoo Tshaj UL Certification rauCov khoom siv LED? Cov Ntsiab Cai Tsim thiab Kev Xaiv Cov Khoom Siv
Txhawm rau nkag mus rau North American LED teeb pom kev lag luam, cov khoom lag luam yuav tsum tsis yog tsuas yog ua tau zoo -tsim thiab txhim khu kev qha tab sis kuj tau txais daim ntawv pov thawj UL kev nyab xeeb dav dav. Ntau lub tuam txhab ntsib kev ncua sij hawm thaum lub sij hawm UL daim ntawv pov thawj txheej txheem vim tsis tsim qauv tsim lossis xaiv cov khoom siv. Raws li cov qauv UL cuam tshuam, kab lus no qhia txog cov kev xav tseem ceeb rauLED qhov muag teevthiab cov raj hauv cov ntsiab lus ntawm cov qauv siv tshuab, hluav taws xob rwb thaiv tsev, thiab lwm yam, pab koj kom tsis txhob muaj teeb meem tshwm sim los ntawm theem tsim thiab dhau daim ntawv pov thawj zoo.
1. Mechanical Structure Design Guidelines
1.1 Teeb Lub Teeb Khoom Xaiv
Cov teeb pom kev zoo hauv North America suav nrog E26, E12, thiab E39. Cov ntaub ntawv yuav tsum ua raws li cov cai hauv qab no:
Copper alloy nrog tsawg kawg yog 80% tooj liab cov ntsiab lus
Nickel alloy los yog stainless hlau
Sab nrauv plating xws li npib tsib xee los yog tin rau corrosion kuj
1.2 Cov khoom ntim thiab Thickness
Hlau Enclosures: Kev tiv thaiv xeb xws li electroplating lossis pleev xim yuav tsum tau ua. Yam tsawg kawg nkaus thickness yuav tsum:
Tuag- ntu ntu: Ntau dua lossis sib npaug li 1.2 hli
Uncoated steel ntawv: Ntau dua lossis sib npaug li 0.66 hli
Tsis yog- ferrous hlau ntawv: Ntau dua lossis sib npaug li 0.81 hli
Plastic Enclosures: nplaim retardancy ntsuas yuav tsum yog tsawg kawg yog 94V-0. Cov yas txhawb nqa qhov chaw nyob yuav tsum ua tau raws li HWI, HAI, thiab CTI cov cai.
2. Cov qauv hluav taws xob muaj kev nyab xeeb
Clearancethiabcreepage nrugnruab nrab ntawm qhov chaw nyob thiab cov khoom siv hlau nkag tau yuav tsum ua raws li cov cai hauv qab no:
|
Ib puag ncig |
Qhov Voltage (V) |
Yam tsawg kawg nkaus Clearance (mm) |
|---|---|---|
|
Qhuav los yog Damp |
Tsawg dua los yog sib npaug li 300 |

Lus Cim: Rau qhov tsis yog -sinusoidal circuits, ob qho tib si RMS thiab qhov siab tshaj plaws yuav tsum tau ntsuas, thiab tus nqi loj dua yuav tsum tau siv rau kev ntsuas.
Tsis tas li ntawd, kev ncua deb ntawm fuse resistors, input terminals (L thiab N), thiab los ntawmLED boardcov npoo rau cov hlau qhov hluav taws xob lossis cov qhov ntsia hlau yuav tsum siab dua lossis sib npaug li 1.2 hli.
3. Ob chav rwb thaiv tsev thiab cov tswv yim hauv av
Thaum RMS voltage rau hauv av tshaj 150V,ob chav rwb thaiv tsevlossis kev tiv thaiv hauv av feem ntau yuav tsum tau ua. Rau compact LED luminaires, cov hauv qab no yuav siv tau:
Kev rwb thaiv tsev yooj yim + rwb thaiv tsev ntxiv (piv txwv li, cua sov shrink tubing + polyester daim kab xev)
Kev siv lub tes tsho yas nrog lub thickness Ntau dua los yog sib npaug ntawm 0.4 hli raws li kev rwb thaiv tsev ntawm tus tsav tsheb thiab cov ntaub thaiv hlau
4. Kev daws teeb meem rau cov teeb meem tshwj xeeb
Ntsuas lub teeb kis tau tus mob thiab nplaim retardancy
Kev siv V-0 nplaim taws- cov ntaub ntawv retardant yuav txo tau lub teeb xa hluav taws xob, cuam tshuam rau cov ntawv pov thawj kev siv hluav taws xob. Xav txog kev tsim kho qhov muag kho qhov muag thiab xaiv cov khoom siv, lossis siv cov khoom siv hluav taws xob nrog cov teeb pom kev zoo dua.
Siv iav Enclosures
Cov iav thaiv feem ntau tsis ua tau raws li UL kev ntsuas kev ntsuas. Xav txog kev sib txuas cov yas thav duab los yog cov txheej txheem cushioning los txhim kho lub zog.
Hluav taws xob Clearance rau me me LED Boards
Yog tias lub rooj tsavxwm loj dhau los ua kom tau raws li qhov yuav tsum tau ua, xav txog kev siv aTsawg Voltage Limited Zog (LVLE)Circuit Court tsim raws li UL8750:
Cov zis hluav taws xob tsawg dua lossis sib npaug rau AC 42.4V ncov (lossis DC 60V)
Cov zis tam sim no Tsawg dua lossis sib npaug rau 8A (hauv qhov ntsuas qhov ntsuas qhov ntsuas)
5. Cov ntsiab lus thiab cov lus pom zoo
UL daim ntawv pov thawj tsis yog ib qho kev thaiv tsis tau. Qhov tseem ceeb nyob hauvsystematic kev npaj thaum lub sij hawm tsim thaum ntxov:
Xaiv cov ntaub ntawv thiab txheeb xyuas qhov kev ncua deb ib kauj ruam raws li UL cov qauv, los ntawm lub hauv paus teeb thiab enclosures mus rau hauv xov hlau
Xav txog cov txheej txheem rwb thaiv tsev thiab kev sib raug zoo nrog cov txheej txheem thermal tswj ua ntej
Flexibly siv cov qauv kev daws teeb meem tshwj xeeb xws li LVLE thaum muaj kev txwv cov qauv
Nws raug nquahu kom koom nrog cov kws tshaj lij pov thawj rau kev tshuaj xyuas kev tsim qauv thaum lub sijhawm txhim kho
Nrog rau kev tsim qauv thiab kev xaiv cov khoom raws li kev cai, UL ntawv pov thawj tuaj yeem dhau los ua "passport" rau kev nkag mus rau kev lag luam zoo dua li tsis muaj kev cuam tshuam.
Daim ntawv pov thawj: UL1993, UL8750, UL2097, UL1310, UL60950, thiab lwm yam qauv.
Tsim nrog ntawv pov thawj hauv siab, thiab tsim cov khoom lag luam uas mus deb.
