Pono e hoʻomaopopo i ke kumu o Semiconductor LED

Ua wili ʻia ke aniani uila Inumgarnet (CE3: yag) i loko o ka pauka a hui pū ʻia me ia i loko o kahi mea hoʻopili paʻa. Ke hoʻopuka ka pahu LED i ke kukui polū, e hoʻololi ʻia kekahi Blu -ray e kēia aniani me kahi ākea o nā spectrals (e pili ana i 580nm i waenakonu o ka spectrum). (ʻOiaʻiʻo, ua manaʻo ʻia ka YAG o ka aniani hoʻokahi i hui pū ʻia me CE e like me ka flicker ma mua o ka phosphorus.) No ka mea, ʻo ke kukui melemele e hoʻoulu i nā mea ʻulaʻula a me ka ʻōmaʻomaʻo i nā maka ʻōlohelohe, ʻo ke kukui uliuli o ka LED ponoʻī e like me ke kukui keʻokeʻo. A kapa pinepine ʻia kona kala “Mahina keʻokeʻo ”. Hoʻokumu ʻia kēia ʻano hana o ke kukui keʻokeʻo e Nichiacorporation a hoʻomaka e hana i ke kukui keʻokeʻo LED ma 1996. ʻAmassaheloaʻa ʻatSherifEhminMama ba ʻāpala, Miss Maole ʻO akam ʻeaPoloiʻOiʻu waBeijing loaʻa home SherifBeijing (ʻAʻole) inei YokSherifpō3: Yang ke, ōa Sherifou loaʻa holkaiwaanSarah pehSherifnei g loaʻa ʻahaka. Ma muli o nā hiʻohiʻona o kona spectrum, ʻoi aku ka liʻiliʻi o nā mea ʻulaʻula a me ka ʻōmaʻomaʻo ma mua o ke kumu kukui ākea ākea ma lalo o kēia ʻike LED. Eia kekahi, ma muli o ka hoʻololi ʻana o nā kūlana hana, ʻaʻole like ka mahana o ka waihoʻoluʻu o kēia huahana i hoʻopau ʻia, mai ka melemele mahana a i ka uliuli anu. No laila, i ka hana hana. ʻO kekahi ʻano keʻokeʻo keʻokeʻo LED e like me ke kukui fluorescent. ʻO ka LED e hoʻopuka ana i nā kukui ultraviolet e pena ʻia me nā hui phosphorus ʻelua, ʻo ka ʻulaʻula a me ke kukui uliuli, a ʻo ka kukui ʻōmaʻomaʻo kekahi. Ke keleawe a me ka alumini me ka zinc sulfide (ZNS). Eia nō naʻe, no ka mea hiki i nā kukui ultraviolet ke hana i ka epoxy resin cracking a me ka hōʻino ʻana i nā adhesives, ʻoi aku ka paʻakikī o ka hana ʻana a pōkole ke ola. Ke hoʻohālikelikeʻia me keʻano mua, he haʻahaʻa haʻahaʻa a hoʻonui i ka wela (no ka mea, he nui mua ka STOKESSHIFT mua), akāʻo ka pōmaikaʻi,ʻoi aku ka maikaʻi o nā hiʻohiʻona o ka spectrum. No ka mea he kiʻekiʻe ka mana LED o ke kukui UV, ʻoiai ʻoi aku ka haʻahaʻa o ka pono, ua like ka ʻōlinolino. ʻO ke ala hou loa no ka hana ʻana i nā LED kukui keʻokeʻo ʻaʻole hoʻohana hou i ke kino māmā phosphorus. ʻO ke ala hou ka ulu ʻana i ka zinc i loko o ka substrate zinc -zinc (ZNSE). Ke hoʻā ʻia, e hoʻokuʻu kona wahi hana i ke kukui polū a e melemele ka substrate, a he kukui keʻokeʻo e hui pū.
