Mulingo wachitetezo wopanda madzi wa LED
Mulingo wachitetezo wamagetsi osalowa madzi a LED umatchedwa IP (International Protection). Ndi nthawi yoyenera yolembedwa ndi IEC (International Electrotechnical Commission) kuti ikhazikitse mikhalidwe yoletsa fumbi, kulowerera kwa thupi lakunja, kusalowa madzi komanso kutsimikizira chinyezi. IP** yomwe nthawi zambiri timawona pa nyali ndi magetsi ndi yomwe timatcha milingo yachitetezo, monga IP45, IP65, IP68.
Mulingo wachitetezo cha IP uli ndi manambala awiri
1. Nambala yoyamba imasonyeza mlingo wa chitetezo ku fumbi ndi zinthu zakunja kuti zilowe mu mankhwala;
2. Nambala yachiwiri imasonyeza kuchuluka kwa mankhwala kulowetsedwa mu chinyezi ndi madzi. Nambala ikakulirakulira, ndiye kuti chitetezo chimakwera.
Tanthauzo la nambala yoyamba:
0 imatanthauza palibe chitetezo, palibe chitetezo chapadera kwa anthu kapena zinthu zakunja.
1 imatanthawuza kupewa kulowerera kwa zinthu zolimba zazikulu kuposa 50mm ndikuletsa thupi la munthu (monga kanjedza) kuti lisagwire mwangozi mbali zamkati. Pewani zinthu zakunja zazikulu (m'mimba mwake kuposa 50mm) kuti zisalowe.
2 imatanthawuza kupewa kulowerera kwa zinthu zolimba zazikulu kuposa 12mm, ndikuletsa kukhudzana kwa zala za munthu ndi ziwalo zamkati. Pewani zinthu zakunja zapakatikati kuti zisalowe (m'mimba mwake wopitilira 12 mm ndi kutalika kupitilira 80 mm).
3 kumatanthauza kupewa kulowerera kwa zinthu zolimba zazikulu kuposa 2.5mm, komanso kupewa kukhudzana ndi mawaya a zida kapena zinthu zing'onozing'ono zakunja zokhala ndi m'mimba mwake kapena makulidwe akulu kuposa 2.5mm.
4 imatanthawuza kupewa zinthu zolimba zokulirapo kuposa 1.0mm kuti zisalowe, ndikuletsa zida, mawaya kapena zinthu zing'onozing'ono zakunja zokhala ndi mainchesi kapena makulidwe opitilira 1.0mm kulowa mkati.
5, amatanthauza fumbi, amaletsa kwathunthu zinthu zakunja kulowa. Ngakhale sizingalepheretse kwathunthu kulowerera kwa fumbi, kuchuluka kwa fumbi losokoneza sikungakhudze ntchito yanthawi zonse.
6, ntchito yoteteza fumbi imalepheretsa zinthu zakunja kulowa, zimalepheretsa fumbi kulowa
Tanthauzo la nambala yachiwiri:
0 imatanthauza palibe chitetezo, palibe chitetezo chapadera kwa anthu kapena zinthu zakunja.
1 kumatanthauza kupewa kulowerera kwa madzi akudontha, ndipo madontho amadzi akudontha molunjika (monga madzi opindika) sangakhale ndi zotsatira zoyipa.
2 imatanthawuza kuti pamene kupendekera kuli 15 °, kulowetsedwa kodontha kumatha kupewedwa. Chogulitsacho chikapendekeka mpaka 15 °, madzi akudontha sangawononge nyali.
3 imatanthawuza kuteteza kupopera kwa madzi, mvula kapena madzi kuti asalowe muzinthu zamtundu wa perpendicular kwa ngodya yosakwana 60 ° ndikuwononga.
4 amatanthauza kupewa kulowerera kwa madzi opaka, kuthira madzi mbali zonse, ndikuwononga.
5 kumatanthauza kuteteza madzi obayidwa kuti asalowe, komanso kuteteza madzi opopera kuchokera kumphuno kumbali zonse kuti asalowe mu mankhwala ndikuwononga.
6 imatanthawuza kupewa kulowerera kwa zinthu zomwe zimayikidwa pa sitimayo kuti ziteteze kuwonongeka komwe kumachitika chifukwa cha kusefukira kwamadzi komwe kumachitika chifukwa cha mafunde akulu.
7 amatanthauza kupewa kulowa m'madzi akamizidwa m'madzi. Kumiza mankhwala m'madzi kwa kanthawi kapena kuthamanga kwa madzi kuli pansi pa muyezo wina kuti kuonetsetsa kuti sichidzawonongeka ndi madzi olowera.
8 amatanthawuza kupewa kulowetsedwa kwa madzi pamene akumira, ndipo pakakhala kumira mopanda malire ndi kuthamanga kwa madzi komwe kumatchulidwa pasadakhale, mankhwalawa sangawonongeke ndi madzi.
Nthawi zambiri, magetsi osagwiritsa ntchito madzi a LED nthawi zambiri amafunikira IP65, inde, zimatengera nthawi zomwe zikuyenera kuchitika, monga momwe nyali yamsewu ya LED IP65 yopanda madzi imatha kupirira, monga kuyatsa kwa LED kuzimbudzi zamkati ndi zimbudzi. Pankhaniyi magetsi a LED IP53 akhoza kukwaniritsa zofuna.
