IK ntsuam xyuas: Ib qho tseem ceeb ntawm LED teeb pom kev zoo
Qib IK08 tau dhau los ua ntau dua rau cov teeb, thiab qee qhov haujlwm txawm hu rau IK10. Ntau tshaj 90 feem pua ntawm cov haujlwm yuav muaj cov qauv ntsuas IK nruj, tshwj xeeb tshaj yog rau cov phiaj xwm teeb pom kev zoo. Dab tsi yog qhov ntsuas IK, thiab vim li cas nws tseem ceeb heev rau lub luminaire? Peb yuav nkag mus rau qhov tob tob ntawm qhov ntsuas IK hnub no.
Qhov qhab nia IK yog dab tsi?
IEC 60068-2-75 tau hloov kho xyoo 1995 European tus qauv BS EN 50102 los tsim cov qauv thoob ntiaj teb tam sim no rau kev kaw cov khoom siv hluav taws xob, hu ua IK rating (los yog kev tiv thaiv kev tiv thaiv). Cov txheej txheem European EN62262, uas yog tib yam li tus qauv thoob ntiaj teb IEC 62262, tom qab ntawd tso tawm hauv 2002 raws li kev ua raws li qhov no (2002). IK kev ntaus nqi yog qhia los ntawm cov ntawv IK thiab tus lej ntawm 00 thiab 10. Nws qhia tau hais tias cov khoom siv hluav taws xob tiv thaiv zoo npaum li cas los ntawm cov khoom siv sab nraud.
Vim li cas IK ntsuas qhov tseem ceeb?
IK Rating cov khoom yog qhov tseem ceeb, tshwj xeeb tshaj yog tias lawv nyob hauv cov chaw pej xeem, chaw tsis khoom, lossis chaw lag luam. Kev nyab xeeb rau ob qho tib si ib puag ncig thiab tib neeg tau lees paub los ntawm IK siab. Nws yog ib qho tseem ceeb kom paub tseeb tias lub teeb tuaj yeem ua haujlwm tau zoo txawm tias lawv puas lossis puas vim muaj kev sib cuag los ntawm cov pob thiab lwm yam khoom hauv qhov chaw tshwj xeeb, xws li cov tsev hais plaub ncaws pob, txoj kev, txoj kev loj, thiab cov chaw ua si. Yog tias nws muaj qhov ntsuas IK qis, nws yuav ua rau tawg, tsim kom muaj kev phom sij, tshwj xeeb tshaj yog nyob rau hauv cov chaw pej xeem, xws li cov khoom tawg lossis tsis muaj teeb pom kev tsim nyog lossis cov ntaub ntawv. Txhawm rau txiav txim siab seb koj xav tau qhov kev sib tw nrog qhov siab lossis qis IK, nws yog ib qho tseem ceeb los ntsuas qhov txaus ntshai ntawm kev cuam tshuam.

Lwm yam ntawm IK xeem
Peb ntseeg hais tias qhov kev ntsuam xyuas IK rau LED teeb pom kev zoo yuav tsum tau ua raws li qhov tsim nyog atmospheric tej yam kev mob (kub thiab siab), nrog rau kev cuam tshuam rau tag nrho lub teeb. Peb kuj yuav tsum xaiv tus naj npawb ntawm cov kev cuam tshuam los tsim, lawv cov kev faib tawm, nrog rau qhov loj me, cov duab, thiab cov khoom siv ntawm ntau yam hammers (khoom) tsim los tsim kom muaj lub zog tsim nyog.
IK Ratings yog li ntawd arbitrary heev. Qhov chaw cuam tshuam tsis tau teev nyob rau hauv EN 62262. Tsis tas li ntawd, kev sim tsis hu rau kev siv cov khoom xws li hinges thiab xauv. Vim tias qhov chaw ntawm qhov cuam tshuam tuaj yeem hloov pauv qhov kev ntsuas ntawm IK, nws yog ib qho tseem ceeb kom nkag siab txog tus neeg tsim khoom cov txheej txheem kuaj. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias yog dab tsi muaj qhov ntsuas IK, nws kuj yuav tsum muaj qhov sib piv IP. Piv txwv li, lub kaw lus yuav raug xaiv raws li IP66 thiab IK06 tib lub sijhawm yog tias nws khaws nws qhov ntsuas IP66 tom qab dhau qhov kev xeem rau IK06 tiv thaiv. Lub kaw lus yuav tsum raug cim raws li IK08 thiab IP54 tiv thaiv lossis IK06 thiab IP66 yog tias nws ua tiav dhau IK08 kev tiv thaiv kev sim tab sis tsuas yog khaws IP54 tiv thaiv. Yuav ua li cas nws tsis tuaj yeem faib ua IK08 thiab IP66 yog tias qhov kev tshawb pom ntawm ib qho kev sim cuam tshuam rau lwm tus. Thov nyeem peb tsab xov xwm ntawm qhov tseem ceeb tshaj plaws IP ntsuam xyuas yog tias koj xav paub txog lub teeb IP ntsuas.
