Thaum xaiv thiab yuav cov khoom siv LED, tshwj xeeb tshaj yog sab nraum zoov cov lus qhia, them nyiaj tshwj xeeb rau ib qho kev ntsuas: IP ntsuas. IP ntsuam xyuas yog dab tsi, thiab dab tsi IP rating zaub koj yuav tsum xaiv? Thov saib hauv qab no.
I. Lub ntsiab lus ntawm IP Rating:
Hauv LED cov lus qhia, qhov ntsuas IP txhais tau hais tias LED zaub muaj peev xwm tiv thaiv cov khoom txawv teb chaws (xws li cov ntiv tes, pob zeb ntawm txoj kev, plua plav, thiab lwm yam) thiab cov khoom ua kua txawv teb chaws (xws li dej nag). Qhov siab dua qhov ntsuas, qhov muaj zog tiv thaiv.
IP sawv cev rau International Protection Marking (IEC 60529), tseem hu ua Ingress Protection Rating lossis IP Code. Qhov no yog IEC (International Electrotechnical Commission) txhais ntawm qib kev tiv thaiv uas cov cuab yeej siv tshuab thiab hluav taws xob tuaj yeem tiv thaiv kev nkag ntawm cov khoom txawv teb chaws thiab nkag mus rau cov kua.
II. Kev sib xyaw ntawm IP ntsuas:
IP Rating=Cov ntawv IP + Thawj tus lej (Cov khoom siv txawv teb chaws tuaj yeem tiv thaiv kev muaj peev xwm) + Tus lej thib ob (Kev muaj peev xwm nkag mus rau cov kua dej) + Cov ntawv ntxiv (yeem) + Cov ntawv ntxiv (yeem). Kev ntsuas IP
Nyob rau hauv tag nrho LED zaub kev lag luam, tus IP ntsuam xyuas yog qhia los ntawm cov tsiaj ntawv "IP" thiab thawj ob tug lej sawv cev rau kev tiv thaiv. Cov ntawv hauv qab no yog xaiv tau lossis ntxiv thiab feem ntau tsis qhia.
III. IP Rating Classification thiab Numerical Lub ntsiab lus:
Thawj tus lej sawv cev rau cov khoom txawv teb chaws ingress tiv thaiv. Tus nqi ntau yog ib tus lej 0-6 lossis tsab ntawv X.
X: Tsis muaj cov ntaub ntawv muaj los qhia txog kev tiv thaiv.
0: Tsis tuaj yeem tiv thaiv kev sib cuag thiab nkag ntawm cov khoom txawv teb chaws.
1: Tiv thaiv cov khoom txawv teb chaws nrog lub cheeb ntawm 50mm lossis loj dua.
2: Tiv thaiv cov khoom txawv teb chaws nrog lub cheeb ntawm 12.5mm lossis loj dua.
3: Tiv thaiv cov khoom txawv teb chaws nrog lub cheeb ntawm 2.5mm lossis loj dua.
4: Tiv thaiv cov khoom txawv teb chaws nrog txoj kab uas hla ntawm 1.0mm lossis loj dua.
5: Dustproof, tab sis tsis tag tiv thaiv plua plav ingress; tus nqi ntawm cov plua plav ingress tsis cuam tshuam rau kev ua haujlwm li qub ntawm cov zaub.
6: Ua tiav plua plav.
Tus lej thib ob sawv cev rau kev tiv thaiv kev nkag mus ua kua. Tus nqi ntau yog ib tus lej 0-8 lossis tsab ntawv X.
X: Tsis muaj cov ntaub ntawv muaj los qhia txog kev tiv thaiv.
0: Tsis tuaj yeem tiv thaiv dej nkag
1: Tiv thaiv cov tee dej
2: Tiv thaiv cov tee dej thaum cov khoom siv tilted ntawm 15 degrees
3: Tiv thaiv cov dej los ntawm dej
4: Tiv thaiv cov dej txau
5: Tiv thaiv cov dej ntws tawm
6: Tiv thaiv cov dej ntws muaj zog
7: Tiv thaiv luv luv - lub sij hawm immersion
8: Tiv thaiv ntev - lub sij hawm immersion
