Pahū ʻo Shenhai
Ma waho aʻe o nā hoʻohālikelike pahū, Hoʻomaʻamaʻa ʻia nā kukui pahū LED no ko lākou hiki ke anti-corrosion. Hāʻule maʻamau nā inoa pahū-hōʻoia i ʻelua ʻāpana: IIB a me IIC. ʻO ka hapa nui o nā kukui LED e hoʻokō i ka maʻamau IIC ikaika loa.
E pili ana i ka anti-corrosion, ua hoʻokaʻawale ʻia nā helu i ʻelua pae no nā kaiapuni o loko a me ʻekolu pae no nā hoʻonohonoho waho. Loaʻa nā pae anti-corrosion i loko o ka F1 no ka haʻahaʻa a me ka F2 no ke kūpaʻa kiʻekiʻe. No nā kūlana waho, ʻO ka hoʻokaʻawale ʻana he W no ka pale ʻana i ka corrosion māmā, WF1 no ka haʻahaʻa, a me WF2 no ka pale ʻana i ka corrosion kiʻekiʻe.
ʻO kēia hoʻonohonoho kikoʻī e hōʻoia i ka hoʻopili ʻia ʻana o nā kukui kukui i nā kūlana kūlohelohe, hoʻonui i ka palekana a me ka lōʻihi.
