ʻO nā LED mana kiʻekiʻe e like me nā kumu kukui aia ma nā wahi āpau, akā pehea ka nui o kāu ʻike e pili ana i nā LED, a ʻo kēia ka mea e lawe iā ʻoe e aʻo i kekahi ʻike e pili ana i nā LED.
Nā hiʻohiʻona puka māmā o nā LED
Me ka holomua wikiwiki o ka ʻenehana LED, ua hoʻomaikaʻi nui nā hōʻailona hana.ʻO ka mea nui, ua hoʻomaikaʻi maikaʻi ʻia ka hana o nā LED keʻokeʻo keʻokeʻo kiʻekiʻe, ʻo ia ke kumu nui o nā kukui ʻehā.E like me nā koi like ʻole o ka hoʻohana ʻana, ʻokoʻa ka mana o kahi pūʻulu hoʻokahi: mai 1 ~ 10W a i nā haneli he nui, mau haneli watts;Mai ka hāʻawi māmā ʻana i nā hiʻohiʻona ikaika o ka lens package LED, ʻo nā mea nui: ʻano Lambertian, ʻano kukui ʻaoʻao, ʻano ʻēheu ʻēheu, ʻano concentrating (collimation) a me nā ʻano ʻē aʻe, a hōʻike ʻia ka pihi hiʻohiʻona i ke kiʻi.
I kēia manawa, ke ulu nei ke ʻano mana keʻokeʻo LED ma ke ʻano o ka mana kiʻekiʻe kiʻekiʻe, akā ma muli o ke kaohi ʻana o ka bottleneck heat dissipation, ka hoʻoheheʻe ʻana o ka wela o kahi chip ultra-large power LED me ka hoʻohana ʻana i ka pūʻulu hui pū ʻana. He mea paʻakikī, a he haʻahaʻa ka māmā māmā. I ka hoʻolālā ʻana o nā kukui alanui LED kiʻekiʻe, pono ke koho ʻana i nā LED mana kiʻekiʻe e noʻonoʻo i nā pilikia he nui e like me nā hiʻohiʻona paʻa mua, ka pono luminous, nā koi kaʻina hana, ke kula kiʻekiʻe a ka hoʻolālā hoʻohele māmā ʻana, hoʻohana i ke kaiapuni, nā kūlana hoʻoheheʻe wela, a me nā hiʻohiʻona puka o ka mea hoʻokele kaʻa.No laila, hui pū ʻia me nā mea i luna, a me nā noi kūpono, ʻo ke ʻano nui o ke koho ʻana i nā LED i nā kukui alanui ʻo ia: ʻo ka mana o kahi LED hoʻokahi e pili ana i 1 watts i kekahi mau watts, ka waihoʻoluʻu maikaʻi ʻana, ka wela o ka waihoʻoluʻu, ka māmā māmā 90 ~100 lm/W nā huahana kiʻekiʻe ke koho maikaʻi loa no ka hoʻolālā.I ka mana o ke kukui alanui, loaʻa ka mana luminous holoʻokoʻa e ka hui ʻana i nā arrays lehulehu;Ma ke ʻano o nā hiʻohiʻona māmā, ʻoi aku ka hoʻohana ʻana o ke ʻano Lambertian, batwing type a me condenser type, akā maʻamau ʻaʻole hiki ke hoʻopili pololei ʻia i nā kukui alanui, pono ma o ka hoʻolālā hāʻawi kukui e hoʻokō i nā koi kukui alanui o nā hiʻohiʻona puka māmā.
