Txhawm rau kom muaj kev nyab xeeb thiab kev ua tau zoo tshaj plaws, nws yog ib qho tseem ceeb kom nkag siab txog cov ntawv pov thawj uas xav tau rau LED tawg resistant qhov muag teev, uas tau nce zuj zus nyob rau hauv cov chaw muaj kev phom sij.
Thaum nws los txog rau kev tawg-pov thawj LED teeb, Daim Ntawv Pov Thawj Qhov Chaw Zoo (HazLoc) yog thawj qhov yuav tsum tau ua. Daim ntawv pov thawj no tau lees tias lub teeb tuaj yeem ua haujlwm zoo nyob rau hauv ib puag ncig uas tej zaum yuav tawg. Ntau lub koom haum thoob ntiaj teb, xws li IEC, EU's ATEX Directive, thiab US's National Electric Code (NEC), saib xyuas HazLoc cov ntawv pov thawj.
Txhawm rau kom tau txais daim ntawv pov thawj HazLoc, LED tawg tiv thaiv lub teeb yuav tsum dhau lub roj teeb ntawm cov kev sim tsim los kom paub tseeb tias lawv yuav tsis teeb hluav taws rau cov hluav taws kub los yog roj av nyob ib puag ncig lawv. Lub peev xwm los tiv thaiv kev poob siab thiab kev co, nrog rau qhov kub thiab txias thiab qhov hluav taws kub, yog tag nrho ntawm cov kev ntsuam xyuas no.
LED tawg resistant qhov muag teev tuaj yeem muaj ntawv pov thawj ntxiv los ntawm pawg xws li UL, CSA, lossis ANSI, ntxiv rau HazLoc. Lub teeb 'ingress tiv thaiv, kev ua haujlwm ntawm qhov kub thiab txias, tiv thaiv corrosion, thiab lub neej ntev tsuas yog qee qhov kev nyab xeeb thiab kev ua haujlwm tau zoo uas cov ntawv pov thawj no lav.
Tsis tas li ntawd, cov teeb pom kev tawg-pov thawj LED tuaj yeem raug pom zoo kom ua tau raws li EMC thiab RFI cov qauv tsim los ntawm cov zej zog thoob ntiaj teb. Lub teeb uas tau txais EMC daim ntawv pov thawj thiab RFI ntawv pov thawj tau raug kuaj xyuas kom ntseeg tau tias lawv tsis ua rau muaj kev cuam tshuam nrog lwm cov khoom siv hluav taws xob lossis cov tshuab hauv cheeb tsam.
Kev siv tshwj xeeb ntawm LED tawg tiv thaiv teeb yuav txiav txim siab cov qauv ntawv pov thawj. Mine kev nyab xeeb thiab kev tswj hwm kev noj qab haus huv (MSHA) thiab daim ntawv pov thawj kev ua haujlwm kev nyab xeeb thiab kev noj qab haus huv (OSHA), piv txwv li, tej zaum yuav tsim nyog rau lub teeb siv hauv cov roj av hauv av lossis cov mines.
Thaum kawg, txhawm rau lav qhov siab tshaj plaws ntawm kev nyab xeeb thiab kev ua tau zoo hauv qhov chaw uas muaj kev phom sij, LED tawg tiv thaiv teeb yuav tsum tau txais ntau daim ntawv pov thawj. Qee cov ntawv pov thawj no yog EMC/RFI, CSA, HazLoc, thiab UL. Txhawm rau kom muaj kev nyab xeeb thiab ua haujlwm tau zoo, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov muag teev uas ua tiav cov ntawv pov thawj cuam tshuam rau daim ntawv thov tshwj xeeb.
