Kuʻi ʻEkolu Lei Lāʻi Lāʻi LED no nā kuhi hewa nui

Misunderstanding mua, ka manaolana o ke ola lawelawe maoli kiʻekiʻe, LED kukui bead mea hana manaʻo i ka LED kukui bead ola a hiki i 100,000 hola. Eia nō naʻe, e like me nā kumu kukui kumu a pau, ua emi iho ka māmā o nā kukui kukui LED i ka manawa. No laila, ʻoiai ka lōʻihi o ka manawa kukui o nā kukui kukui LED, ʻaʻole ʻo MTBF wale nō ka noʻonoʻo no ka hoʻoholo ʻana i ke ola lawelawe. Hoʻopilikia ʻia ka palaho o nā kukui kukui LED e nā kūlana kaiapuni e like me ka mahana o ke kaiapuni, ka haʻahaʻa a me ka ea. Hoʻopili pū ʻia ka mana o ka attenuation lōʻihi e ka hoʻomalu ʻana, ka hoʻokele ʻepekema wela, ke degere o kēia manawa, a me ka noʻonoʻo ʻana i nā hoʻolālā uila ʻē aʻe. Hiki i nā mea kūʻai aku ke hāʻawi i kekahi ʻike i nā mea kūʻai aku i ke kūʻai ʻana i nā pahu kukui LED, e alakaʻi hewa ana, e like me ke ola lawelawe o nā pahu kukui LED i 100,000 mau hola. ʻO nā hola 100,000 ma aneʻi ʻo ia ka mea e manaʻo nei ka mea hana i ke ola o ke ola kukui LED. Eia nō naʻe, ma ke ʻano he kumu kukui o ke kukui, ʻo ka ʻōlinolino o nā kukui ke kaʻina o ka pohō ʻana i ka pōʻeleʻele (e like me ka lā, nā kukui mālama ikehu). ʻO kēia kaʻina hana i kapa ʻia he pohō māmā. No laila, i ka wā e kūʻai ai nā mea kūʻai aku i nā kukui kukui LED, pono lākou e hoʻolohe i kona māmā atance rate, ʻaʻole hoʻohana i ka manawa, a ʻaʻole manaʻo nā mea kūʻai aku i ke ola maoli. Misunderstanding 2, e puunaue i ka huina kukui maoli e like me ke kihi pono o na pahu kukui LED i kahi kihi pono a me ka huina kukui-emitting maoli. ʻO ke kumu o ka waiwai pahuhopu o ka waiwai ikaika axial o ka māmā -emitting intensity he kihi kūpono me ka angle o ke kukui emitting axial (ʻano). ʻElua manawa o ka huina o ka hapalua -value angle ke kuanaʻike (a i ʻole ka semi-power angle) ʻo ia ka huina kukui maoli. Mai ke kihi o ka hapalua o ka ikaika axial no ka mea ua nāwaliwali loa ka mālamalama i ka noi maoli, ʻaʻole ia e helu i ka kihi pono. No laila, pono e hoʻolohe nā mea kūʻai aku i ke kihi kukui maoli o ka huahana i ke kūʻai ʻana i nā huahana. I ka helu ʻana i ka helu o nā huahana i hoʻohana ʻia i ka papahana, ua hoʻokumu ʻia ia ma ke kihi kukui maoli. Misunderstanding 3, ʻoi aku ka kiʻekiʻe o ka ʻōlinolino, ʻoi aku ka kiʻekiʻe o ka ʻōlinolino o nā kukui kukui LED me ka ikaika o ka hoʻomālamalama ʻana, a ʻo ka hoʻomālamalama ʻana o ke kukui e pili ana i ka ikaika o ka hoʻoheheʻe ʻana i ka pahu o ka laina ala (i ka cylindrical luminous pipe e pili ana i kāna. axis) ʻO ke kukui kukui he kukui kukui (CD). Ma muli o ka liʻiliʻi o ka nui o nā kukui kukui LED maʻamau, hoʻohana pinepine ka māmā hoʻomāmā i nā ʻāpana. ʻO ka ʻōlelo maʻamau, e hoʻomālamalama ke kumu kukui i kona ʻano opi i ka pahuhopu ʻokoʻa o nā pahu kukui LED Domestic me nā ikaika like ʻole. Mai ka manaʻo o ka nui o ka hana i ka mana i ka manawa hoʻokahi, wikiwiki ke au, wikiwiki ke au, ʻo ka uila ka makahiki o ka mana; lohi ke au, liʻiliʻi ka mana uila, a ʻoi aku ka nui o ke au i ke au, ʻoi aku ka nui o ka uila, ʻoi aku ka nui o ka uila. Ma nā kukui kukui LED, ʻoi aku ka kiʻekiʻe o ka mana, ʻoi aku ka kiʻekiʻe o ka mālamalama o ka huahana. ʻO ka lawe ʻana i ʻekolu mau kukui kukui ʻulaʻula ʻulaʻula o Yimei Electronics ma ke ʻano he laʻana, i ka wā ʻo 1200mcd ka kukui axial, ʻo 40mA ka mana a ʻo 0.48W ka mana; Hiki keʻikeʻia heʻokoʻa ka mana o nā kukuiʻelua ma lalo o ka'ōlinolino o ke kukui. No laila, i ka wā e kūʻai ai nā mea kūʻai aku i nā kukui kukui LED, pono lākou e hoʻolohe i kona kukui axis, ʻaʻole ka mana. Mai nā lei kukui LED http://.
