No ke aha i makemake nui ai ka poʻe e hoʻohana i nā kukui LED ma mua o nā kukui incandescent?

Eia kekahi mau hoʻohālikelike, hiki paha ke kōkua iā mākou e ʻike i ka pane.

ʻO ka ʻokoʻa mua ma waena o nā kukui incandescent a me nā kukui LED ʻo ia ke kumu hoʻomālamalama.Ua kapa ʻia ke kukui uila he ʻōpuʻu uila.ʻO kāna kumu hana ʻo ia ka wela i ka wā e hele ai ke au i ka filament.ʻOhi mau ka filament spiral i ka wela, e hana ana i ka mahana o ka filament ma mua o 2000 degere Celsius.Aia ke filament i ke ʻano ʻulaʻula.Hiki iā ia ke hoʻopuka i ka mālamalama e like me kona ʻālohilohi.

ʻO ke kiʻekiʻe o ka mahana o ka filament, ʻoi aku ka māmā o ke kukui, no laila ua kapa ʻia ʻo ia he kukui kukui.Ke hoʻopuka nā kukui incandescent i ka mālamalama, e hoʻololi ʻia ka nui o ka ikehu uila i ikehu wela, a ʻo kahi hapa liʻiliʻi wale nō e hiki ke hoʻololi i ka ikehu māmā pono.

Ua kapa ʻia nā kukui LED i nā kukui-emitting diodes, ʻo ia nā mea semiconductor solid-state e hiki ke hoʻololi pololei i ka uila i mālamalama.ʻO ka puʻuwai o ka LED he puʻupuʻu semiconductor, hoʻopili ʻia kekahi ʻaoʻao o ka chip i kahi bracket, ʻo kekahi ʻaoʻao ka pole maikaʻi ʻole, a ʻo kekahi ʻaoʻao e pili ana i ka pou maikaʻi o ka lako mana, i hoʻopili ʻia ka chip holoʻokoʻa. e ka epoxy resin.

Hoʻokumu ʻia ka wafer semiconductor i ʻekolu mau ʻāpana, hoʻokahi ʻāpana he semiconductor P-type, kahi e noho aliʻi ai nā lua, ʻo ka ʻaoʻao ʻē aʻe he semiconductor N-type, eia ka nui o nā electrons, a ʻo ka waena maʻamau he quantum well me 1 a 5 nā pōʻaiapuni.I ka hana ʻana o kēia manawa i ka chip ma o ka uea, e hoʻolei ʻia nā electrons a me nā lua i loko o nā luawai quantum.I loko o nā pūnāwai quantum, hui hou nā electrons a me nā lua a laila e hoʻokuʻu i ka ikehu ma ke ʻano o nā photon.ʻO kēia ke kumu o ka hoʻokuʻu kukui LED.

Aia ka lua o ka ʻokoʻa i ka pāhawewe wela i hana ʻia e nā mea ʻelua.Hiki ke ʻike ʻia ka wela o ke kukui uila i ka manawa pōkole.ʻO ka nui o ka mana, ʻoi aku ka wela.ʻO kahi o ka hoʻololiʻana o ka ikehu uila he māmā a he hapa o ka wela.Hiki i nā kānaka ke ʻike maopopo i ka wela i hoʻopuka ʻia e ke kukui ʻālamalama ke kokoke loa lākou..

Hoʻololi ʻia ka ikehu uila LED i ikehu māmā, a he liʻiliʻi loa ka pāhawewe wela.ʻO ka hapa nui o ka hiki ke hoʻololi pololei i ka ikehu māmā.Eia kekahi, haʻahaʻa ka mana o nā kukui maʻamau.Hoʻohui pū ʻia me ke ʻano hoʻoheheʻe wela, ʻoi aku ka maikaʻi o ka radiation wela o nā kumu kukui anuanu LED ma mua o nā kukui incandescent.

ʻO ke kolu o ka ʻokoʻa, he ʻokoʻa nā kukui i hoʻopuka ʻia e nā mea ʻelua.ʻO ke kukui i hoʻokuʻuʻia e ke kukui'ōniʻoniʻo he kukui kala piha, akā,ʻo ka ratio o nā kukui kala likeʻole e hoʻoholoʻia e ka mea luminescent a me ka mahana.ʻO ka lakio kaulike ʻole ke kumu o ke kala kala o ke kukui, no laila ʻaʻole lawa maoli ke kala o ka mea ma lalo o ke kukui kukui.

ʻO LED kahi kumu kukui ʻōmaʻomaʻo.Ke alakaʻi ʻia nei ke kukui LED e DC, ʻaʻohe stroboscopic, ʻaʻohe infrared a me nā ʻāpana ultraviolet, ʻaʻohe pollution radiation, kiʻekiʻe kiʻekiʻe o ka waihoʻoluʻu kala a me ke kuhikuhi kukui ikaika.

ʻAʻole ʻo ia wale nō, ʻo ke kukui LED he hana dimming maikaʻi, ʻaʻohe hewa ʻike i ka wā e hoʻololi ai ka mahana o ke kala, a he haʻahaʻa haʻahaʻa ke kumu kukui anuanu a hiki ke hoʻopā ʻia.Hiki iā ia ke hāʻawi i kahi lumi kukui ʻoluʻolu a maikaʻi He kumu kukui olakino ia e pale ai i ka ʻike maka a me ke kaiapuni e hālāwai me nā pono olakino physiological o nā kānaka.
