LED teeb tau dhau los ua ib feem tseem ceeb ntawm peb lub neej thaum peb siv lawv rau ntau lub hom phiaj, suav nrog teeb pom kev hauv peb lub tsev, tsheb, thiab qhov chaw sab nraum zoov. Txawm li cas los xij, txhua lub teeb ci LED tuaj nrog IP (Ingress Protection) ntsuas uas txhais tau tias nws muaj peev xwm tiv taus ntau yam ib puag ncig. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov qib IP sib txawv thiab lawv cov lus txhais.
Ua ntej, nws yog qhov tseem ceeb kom nkag siab tias qib IP muaj ob tus lej. Thawj tus lej sawv cev rau kev tiv thaiv cov khoom siv xws li plua plav, thaum tus lej thib ob sawv cev rau qib tiv thaiv cov kua xws li dej.
Thawj tus lej nyob ntawm {{0}}, nrog 0 tsis muaj kev tiv thaiv los ntawm cov khoom siv thiab 6 yog plua plav-nruj. Piv txwv li, lub teeb ci LED nrog qhov ntsuas IP6X txhais tau hais tias nws tag nrho cov plua plav nruj thiab yuav tsis tso cov plua plav nkag mus.
Tus lej thib ob yog nyob ntawm {{0}}, nrog 0 tsis muaj kev tiv thaiv los ntawm cov kua thiab 9 yog dej-resistant. Piv txwv li, lub teeb ci LED nrog qhov ntsuas IPX0 txhais tau tias nws tsis muaj kev tiv thaiv dej. Ntawm qhov tod tes, lub teeb LED nrog qhov ntsuas IPX9 txhais tau hais tias nws tiv taus cov dav hlau siab ntawm cov dej.
Raws li koj tuaj yeem pom, tsab ntawv 'X' nyob rau hauv qhov kev ntaus nqi sawv cev rau lub ntsiab lus 'tsis suav'. Piv txwv li, lub teeb ci LED nrog qhov ntsuas IPX6 txhais tau hais tias nws tsis muaj qhov ntsuas tshwj xeeb tiv thaiv cov khib nyiab, tab sis nws yog dej nruj.
Nov yog qhov kev faib tawm ntawm cov qib IP sib txawv thiab lawv cov ntsiab lus:
- IP44: Qhov kev ntsuam xyuas no txhais tau hais tias lub teeb LED tiv thaiv cov khoom loj dua 1 hli thiab dej txaws, feem ntau yog siv rau hauv qhov chaw sab nraum zoov.
- IP65: Qhov kev ntsuam xyuas no txhais tau hais tias lub teeb ci LED yog plua plav nruj thiab tiv thaiv cov dav hlau dej uas tsis tshua muaj siab, ua rau nws zoo tagnrho rau qhov chaw sab nraum zoov.
- IP67: Qhov kev ntsuam xyuas no txhais tau hais tias lub teeb ci LED yog plua plav nruj thiab tuaj yeem tiv taus kev nkag mus rau hauv dej mus txog ib lub 'meter' tob, ua rau nws zoo tagnrho rau cov teeb pom kev hauv qab dej thiab qhov chaw sab nraum zoov.
- IP68: Qhov kev ntsuam xyuas no txhais tau hais tias lub teeb ci LED yog plua plav nruj thiab tuaj yeem tiv taus txuas ntxiv rau hauv dej tshaj li ib 'meter' qhov tob, ua rau nws zoo tagnrho rau cov teeb pom kev hauv qab dej.
Hauv kev xaus, kev nkag siab txog ntau qib IP yog qhov tseem ceeb thaum xaiv lub teeb LED rau koj cov kev xav tau tshwj xeeb. Nws tsim nyog sau cia tias qhov siab dua qhov ntsuas IP, qhov siab dua qhov kev tiv thaiv ib puag ncig.
