ʻO ka ʻikepili i ʻike ʻia e ke kukui keʻokeʻo LED hoʻokahi ma ka papa ʻelemakule, ka hōʻike aniani moakaka a me nā ʻike i ʻike ʻia ke hui ʻia ke kukui keʻokeʻo LED i loko o kahi luminaire he loaʻa kālā kēia.
Aia ka nui o kēia ʻokoʻa i nā palena uila o ka hana LED a me ka hoʻolālā o ka luminaire, a me ke kaiapuni kahi e hoʻohana ai ka luminaire.
ʻO ka mea, he aha ke ʻano o ke kukui keʻokeʻo LED i koho ʻia.
He mea nui loa kēia, hiki ke ʻōlelo ʻia ke ʻano o ke kukui keʻokeʻo LED he mea nui nui ia. No kekahi mau laʻana, hoʻohana ʻia ka mahele ʻāpana keʻokeʻo mālamalama 14mil ma ke ʻano he lunamakaʻāinana, a me ke kukui keʻokeʻo LED i hoʻopili ʻia e ka resin epoxy ākea a me ke aniani keʻokeʻo a me ka ʻōpala pūʻolo e hoʻomālamalama ʻia i kahi kaona 30 kekelē. Ma hope o 1000 mau hola, ʻo ka ʻike atenuation he 70% palaho kukui; inā ʻūlū ʻia me ke kāpili kūpaʻa haʻahaʻa ʻano D, i ke ʻano kūnewa like, 45% ka palaho māmā; inā ʻākoʻomo ʻia ke kāpili C-type low-resist, i loko o ke ʻano ʻelemakule like. Inā hoʻopili ʻia ka pelu momona momona B, ma ke ʻano like o ka ʻelemakule, -3% ka palahu māmā o ka tausani liʻiliʻi; inā ʻo ke kāpili haʻahaʻa o ke ʻano A, i ke ʻano like o ka ʻelemakule, ka tausani liʻiliʻi o ka wanaʻao popopo a -6%.
No ke aha e alakaʻi ai i nā ʻūlū ʻokoʻa i nā ʻokoʻa nui?
ʻO kekahi o nā kumu nui ka makaʻu o nā ʻāpana LED i ka wela. I kekahi manawa, ʻoi aku ka nui o ka wela ma mua o hoʻokahi haneli mau kekelē i kahi manawa pōkole, ʻaʻole ia he mea nui, makaʻu no ka manawa ma lalo o ke ana wela no ka manawa lōʻihi, he mea ʻino nui ia i ka ʻāpana LED.
'Lelo maʻamau, ʻo ka conductivity thermal o ka epoxy resin he mea liʻiliʻi ia. No laila, ke hoʻomālamalama ʻia ka puʻukū LED, hoʻopuka ka chip LED i ka wela, a me ka resin epoxy ākea i kaupalena ʻia ka conductivity thermal, no laila ke hele ʻoe mai ke kukui keʻokeʻo LED i waho, ana ʻia ka mahana o ka mea paʻa LED ma 45 kekelē, a ʻo ka ʻoi aku ka nui o ka mahana o ka chip i ke LED keʻokeʻo ma mua o 80 kekelē. ʻO ka pona mahana o ka LED he 80 kekelē. A laila, ke hoʻohana ʻia ka chip LED i ka mahana o ke ana wela, hoʻomāʻehaʻeha loa ʻia ia, kahi e wikiwiki ai ka ʻelemakule o ke kukui keʻokeʻo LED.
Ke hana nei ka ipukukui LED, hoʻonui ka mahana waena i kahi mahana kiʻekiʻe o 100 kekelē, a hiki i ka hōʻike aniani moakaka ke hoʻokuʻu koke i ka wela ma o ka pin bracket 98%, no laila e hōʻemi ana i ka hōʻino o ka wela. No laila, ke 60 kekelē ke ana wela keʻokeʻo kukui keʻokeʻo, ʻo 61 kekelē wale nō kona mahana wela.
Hiki ke ʻike ʻia mai ka ʻikepili ma luna aʻe ke koho ʻia ke kukui keʻokeʻo LED o ke kaʻina hoʻopili ʻana e koho pololei i ke ʻano o ka palaho kukui o ke kukui LED.
