I loko o ka ʻenehana kukui kaʻa hou, nā kukui halogen, HID (nā kukui hoʻokuʻu kino kiʻekiʻe) a me nā kukui LED (light-emitting diode) nā ʻano maʻamau ʻekolu. Loaʻa i kēlā me kēia kukui kona mau pono a me nā hemahema, akā ma lalo o nā kūlana mana like, ʻo ka wela i hana ʻia e nā kukui ʻokoʻa he ʻokoʻa nui.
Nā kukui halogen
ʻO nā kukui halogen ke ʻano kuʻuna o nā kukui uila. ʻO kāna kumu hana e like me nā kukui incandescent maʻamau, a ua wela ka filament tungsten e ka uila e hoʻomālamalama. Hoʻopihaʻia ka pūpū aniani o ke kukui halogen i ke kinoea halogen (e like me iodine a iʻole bromine), hiki ke hoʻonui i ke ola o ka filament a hoʻonui i ka'ōlinolino.
Eia kekahi, hoʻonui nā kukui halogen i ka wela nui, hoʻopau i ka nui o ka ikehu, a hiki ke piʻi ka mahana ma mua o 200 degere Celsius i ka wā e hana ai.
ʻO nā kukui HID, i ʻike ʻia hoʻi he mau kukui hoʻokuʻu kinoea kiʻekiʻe, e hoʻopuka i ka mālamalama ma o ka hoʻopiha ʻana i ka puʻupuʻu me nā kinoea inert e like me xenon a me ka hana ʻana i kahi arc ma lalo o ka volta kiʻekiʻe.
Hiki i ka mahana o nā kukui HID ke piʻi i 300-400 degere Celsius ke hana ʻoi aku ma mua o ʻumi mau minuke ma hope o ka hoʻāla ʻana, ʻoiai ʻoi aku ka haʻahaʻa o ka mahana ma waho o ka puʻupuʻu ma mua o ka wela kumu, a hoʻohana mau ʻia ka hoʻoluʻu kūlohelohe.
ʻO nā kukui LED he ʻano kukui kaʻa i lilo i mea kaulana i nā makahiki i hala. Hoʻopuka ia i ka mālamalama ma o nā diodes māmā ma lalo o ka hana o kēia manawa, a loaʻa iā ia nā hiʻohiʻona o ka hana kiʻekiʻe a me ka mālama ʻana i ka ikehu.
He haʻahaʻa ka wela i hana ʻia e nā kukui LED, ma kahi o 80 degere Celsius. ʻO kēia no ka mea kiʻekiʻe ka hoʻololi electro-optical o nā kukui LED, a ua hoʻololi ʻia ka hapa nui o ka ikehu i ka ikehu māmā ma mua o ka ikehu wela.
No ke aha e hana ai ʻo LEDpoʻoliʻiliʻi ka wela o nā kukui?
Hoʻololi electro-optical
He kiʻekiʻe loa ka hoʻololi electro-optical o nā kukui LED, a ʻo ka hapa nui o ka ikehu uila hiki ke hoʻololi i ka ikehu māmā. ʻO ka ʻokoʻa, nā kukui halogen a me nā kukui HID e hoʻoulu i ka wela i ka wā o ke kaʻina hana kukui.
Haʻahaʻa mana hoʻohana
He haʻahaʻa ka mana o nā kukui LED, maʻamau mai kahi mau watts a hiki i ʻumi mau watts, ʻoiai nā kukui halogen a me nā kukui HID ʻoi aku ka nui o ka hoʻohana mana.
Nā mea semiconductor
Hoʻohana nā kukui LED i nā mea semiconductor e hoʻokuʻu i ke kukui, ʻaʻole ia e hoʻohua i ka wela nui e like me nā filament tungsten i ka wā e hele ai kēia manawa. ʻOi aku ka maikaʻi a me ka paʻa o ke kaʻina hana māmā o nā mea semiconductor.
Hoʻolālā hoʻoheheʻe wela
ʻOiai ʻo nā kukui LED ponoʻī e hana i ka wela haʻahaʻa, ʻoi aku ka maʻalahi o ka wela, no laila pono nā kukui LED i nā hana hou e kōkua i ke kukui holoʻokoʻa e hoʻopau ikaika i ka wela.
Nui nā ala e hiki aihoʻopau i ka wela no nā kukui LED. ʻO ke ala hoʻoheheʻe wela kaulana loa he radiator + fan.
ʻO ke kukui LED me ka hoʻopau wela kūpono
ʻO kēiaPuku kukui LED K11hana ʻia me ka alumini aviation, nona ka lōʻihi maikaʻi a me ka wela wela. Hoʻohana ka loko o ke poʻo i ka superconducting thermal copper material a me ka hoʻolālā hoʻoluʻu hoʻoluʻu, ʻaʻole ia he kiʻekiʻe i ka ʻōlinolino, akā loaʻa nō hoʻi ka wela wela a me ke ola lawelawe.
Hiki i kēia kukui ke kū i nā kaiapuni kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a loaʻa iā ia kahi peʻahi wai i kūkulu ʻia, hiki iā ia ke hāʻawi iā ʻoe i nā hopena kukui maʻemaʻe i loko o nā kūlana kaiapuni paʻakikī.
Inā makemake ʻoe e ʻike hou aku a kūʻai paha i nā kukui kaʻa, e ʻoluʻolu e kelepona pololei i nā luna WWBIU:
