Ka nānā 'ana i nā kumu o ka pohō kukui LED
Ma ke ʻano he ʻano hou o nā kukui kukui ʻōmaʻomaʻo, ʻo nā kukui LED e mālama i ka ikehu, pili kaiapuni a lōʻihi ke ola. Nui ka mākeke hiki. Eia nō naʻe, ʻo ka pilikia o ka palaho kukui LED kekahi pilikia ʻē aʻe e kū pono ai nā kukui LED. ʻO ka pohō māmā ʻole, pili nui i ka hoʻohana ʻana i nā kukui LED.
No ka manawa, ʻo ka pohō māmā o nā LED keʻokeʻo ma ka mākeke paha kekahi o nā pilikia kiʻekiʻe no nā kukui kīwila. Ma ka laulā, ʻelua mau kumu nui no ka pohō māmā o nā LED:
Ka mualy, ka maikaʻi o nā huahana LED iā lākou iho:
1. ʻAʻole maikaʻi ka chip LED i hoʻohana ʻia, a ʻoi aku ka wikiwiki o ka ʻōlinolino.
2, he hemahema ke kaʻina hana, ʻaʻole hiki ke hoʻokuʻu maikaʻi ʻia ka wela chip LED mai ka wela wela, e hopena i ka wela kiʻekiʻe o ka chip LED e hana i ka attenuation chip.
Ka lualy, ka makoumanā kūlana:
1. Ke alakaʻiʻia nei ka LED e ka manawa mau, aʻo kekahi o nā LED e hoʻouluʻia e ka voltage e hoʻonā i ka LED.
2. ʻOi aku ka nui o ke kaʻa o kēia manawa ma mua o ke kūlana hoʻokele helu.
ʻOiaʻiʻo, nui nā kumu no ka pohō māmā o nā huahana LED. ʻO ka pilikia koʻikoʻi ka pilikia wela. ʻOiai ʻaʻole nānā nui nā mea hana i ka hoʻopau ʻana o ka wela i nā huahana lua, ʻoi aku ka māmā o ka hoʻohana ʻana i kēia mau huahana LED lua. Pono nā huahana LED hoʻoluʻu kiʻekiʻe. ʻO ke kūpaʻa wela o ka chip LED ponoʻī a me ka hopena wela o ka substrate e pili pū ana me ka palaho māmā.
ʻEkolu mau LED hopena ʻO ke kumu hoʻomāmā māmā maikaʻi o ke kukui
ʻO ka mea mua, ke koho ʻana i nā kukui kukui LED.
ʻO ka maikaʻi o nā kukui kukui LED hiki ke ʻōlelo ʻia he kumu nui loa. ʻO nā pahu kukui LED o nā ʻenehana hana like ʻole he ʻokoʻa ka wikiwiki o ka pohō māmā. No ka laʻana, ʻaʻole kūʻai nā mea hana he nui i nā pahu kukui i lawe ʻia mai. Kūʻai ʻo OAK i nā pahu kukui CREE LED kumu mua o ʻAmelika. ʻOi aku ka kiʻekiʻe o ka ʻenehana hoʻopihapiha holoʻokoʻa ma mua o nā peʻa kukui LED ʻē aʻe i ka ʻoihana like, he mau mea maikaʻi loa i ka māmā māmā a me ke kūpaʻa wela kiʻekiʻe.
Ka lualy, ke kukui LEDhana anamahana wela.
Wahi a ka CREE LED lamp bead aging data, i ka wā e hana ana ke kukui kukui LED, he 30 degere ka wela o ka wela, a laila he 60-70 degere ka mahana hana o ka pahu kukui LED hoʻokahi. ʻO kēia ka mahana hana kūpono no ka hoʻohana lōʻihi.
Makaʻu ʻo LED i ka wela, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ke kukui kukui LED, ʻoi aku ka pōkole o ke ola o LED, ʻoi aku ka haʻahaʻa o ka mahana o ke kukui kukui LED, ʻoi aku ka lōʻihi o ke ola LED. No laila, i ka hoʻolālā ʻana i ka luminaire, hoʻonui ʻia ka hana o ka conduction wela a me ka dissipation wela e hoʻonui i ke ola o ke kukui LED.
ʻO ke kolu, Hoʻolālā ʻia nā ʻāpana uila hana o ke kukui kukui LED.
Wahi a ka hoʻokolohua, ʻoi aku ka haʻahaʻa o ke au o ke kukui kukui LED, ʻoi aku ka liʻiliʻi o ka wela, a ʻoi aku ka liʻiliʻi o ka mālamalama.
Ma ka hōʻuluʻulu , Pono ka hoʻolālā ʻana o nā ʻāpana uila hana o ke kukui kukui LED ma ke kūlana maoli. Inā maikaʻi loa ka hana wela a me ka hoʻoheheʻe wela o ke kukui, hiki ke hoʻokuʻu pololei ʻia ka wela i hana ʻia e ka hana o ke kukui kukui LED i waho me ka ʻole o ka pōʻino i ka LED.
