ʻAʻole e ʻike koke ʻia nā kukui alanui LED

i kēia manawa, ʻaʻole kūlike ka pae maikaʻi o nā kukui alanui LED ma ka mākeke. Ma nā wahi he nui, ʻaʻole e ʻike koke ʻia nā kukui alanui LED. Ma hope o ka noiʻi ʻana o kaNā kukui alanui alakaʻiʻO ke kumu kumu o kēia ʻano, ʻo ke kukui alanui LED he maikaʻi ʻole ka hana hoʻoheheʻe wela. Ke haʻahaʻa ka hana hoʻopau wela, e kiʻekiʻe loa ka mahana o loko o ke kukui LED. Ke piʻi aʻe ka mahana o ka LED, e emi ana kona kūpaʻa junction, e hopena i ka emi ʻana o ka volta hoʻohuli.

Ma lalo o nā kūlana voltage like, ʻo ka piʻi ʻana o ka mahana o loko o ke kukui LED e hoʻonui i ka manawa LED. ʻO ka piʻi ʻana o kēia manawa ke piʻi hou aʻe ka mahana, ʻo ia ka mea e puhi ai ka pōʻai maikaʻi i ka chip LED. Eia kekahi, ʻoi aku ka kiʻekiʻe o ka mahana o loko o ke kukui alanui LED, a ʻo ia hoʻi ka mea e hoʻonui ai i ka pohō māmā o ka chip LED, no laila e alakaʻi i kahi ʻano ʻālohilohi a ʻaʻole hoʻi i ka wā e hiki mai ana. No laila he aha ke kumu no ka maikaʻi ʻole o ka hoʻoheheʻe ʻana i ka wela o ke kukui alanui LED?

ʻO ka mea mua, ʻo ka maikaʻi o nā kukui alanui LED iā lākou iho.

ʻO ka chip LED i hoʻohana ʻia he maikaʻi ʻole ka thermal conductivity, a ʻaʻole i lawe ʻia ka mahana o ka make LED i ka ʻili (ka wela o loko a me ke anu). ʻOiai inā hoʻohui ʻia kahi wela wela, ʻaʻole hiki ke hoʻopau loa ʻia ka wela o loko, a laila ʻaʻole wela i loko ke kukui alanui LED.

ʻO ka lua, ʻo ka piʻi ʻana o ka wela ma muli o ke kukui alanui LED.

ʻAʻole maikaʻi ka mana kukui alanui LED. Ke hoʻololiʻia ka LED,ʻo ka lainaʻole o ka mana a me ka hoʻololi nāwaliwali o ka mana e hoʻonui i ka manawa ma o ka chip LED, kahi e piʻi nui ai ka mahana o loko, e pili ana i ka wela. ka hana hoʻopau ʻana o ke kukui alanui LED.

Pono nā kānaka a pau e nānā i ka lōʻihi o nā kukui alanui LED. I ke kūʻai ʻana, e hoʻāʻo e koho i nā mea hana kukui alanui LED hilinaʻi, a e hoʻolohe pū i ka mālama mau ʻana, i mea e hōʻoia ai i ka paʻa o nā kukui alanui LED.
