1. Polū-LED puʻupuʻu + melemele-'ōmaʻomaʻo phosphor 'ano me multi- waihoʻoluʻu phosphor derivative 'ano

 Hoʻopili ka ʻāpana phosphor melemele-'ōmaʻomaʻo i kahi hapa o kakukui uliuliʻO ka chip LED e hana i ka photoluminescence, a ʻo ka ʻāpana ʻē aʻe o ke kukui polū mai ka chip LED e hoʻoili ʻia mai ka papa phosphor a hui pū me ke kukui melemele-'ōmaʻomaʻo i hoʻokuʻu ʻia e ka phosphor ma nā wahi like ʻole o ka lewa, a hui pū ʻia ke kukui ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli e hana i ke kukui keʻokeʻo; Ma kēiaʻano,ʻo ka waiwai kiʻekiʻe o ka phosphor photoluminescence ka hoʻololiʻana i ka pono,ʻo ia kekahi o ka maikaʻi quantum waho,ʻaʻole eʻoi aku ma mua o 75%; a ʻo ka māmā kiʻekiʻe loa o ka unuhi ʻana mai ka chip hiki ke hiki wale ma kahi o 70%, no laila ma ke kumumanaʻo, ke kukui keʻokeʻo uliuli ʻAʻole e ʻoi aku ka maikaʻi o ka luminous LED kiʻekiʻe ma mua o 340 Lm/W, a hiki i ka CREE i 303Lm/W i nā makahiki i hala. Inā pololei nā hopena hōʻike, pono e hoʻolauleʻa.

2. ʻO ka hui pū ʻana o ka ʻulaʻula, ka ʻōmaʻomaʻo a me ka uliuliLED RGBʻO ke ʻano he ʻano RGBW-LED, etc.

 Hoʻohui pū ʻia nā diodes kukui-emitting ʻekolu o R-LED (ʻulaʻula) + G-LED ('ōmaʻomaʻo) + B- LED (uliuli), a ua hui pololei ʻia nā waihoʻoluʻu kumu ʻekolu o ka ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli i loko o ke ākea e hana i ke kukui keʻokeʻo. I mea e hana ai i ke kukui keʻokeʻo kiʻekiʻe ma kēia ala, ʻo ka mea mua, nā LED o nā waihoʻoluʻu like ʻole, ʻoi aku ka ʻōmaʻomaʻo LED, pono nā kumu kukui kiʻekiʻe, hiki ke ʻike ʻia mai ka "kumu keʻokeʻo like ikehu" ma kahi o 69%. I kēia manawa, ua kiʻekiʻe loa ka maikaʻi o nā LED uliuli a me ka ʻulaʻula, me ka nui o ka nui o loko ma mua o 90% a me 95%, kēlā me kēia, akā ʻoi aku ka maikaʻi o ka quantum kūloko o nā LED ʻōmaʻomaʻo. Ua kapa ʻia kēia ʻano o ke kukui ʻōmaʻomaʻo haʻahaʻa o nā LED i hoʻokumu ʻia i ka GaN ʻo ka "'ōmaʻomaʻo ʻōmaʻomaʻo." ʻO ke kumu nui ʻaʻole i loaʻa i nā LED ʻōmaʻomaʻo kā lākou mau mea epitaxial ponoʻī. Loaʻa ka haʻahaʻa haʻahaʻa o nā mea moʻo phosphorous arsenic nitride i kēia manawa i ka spectrum melemele-'ōmaʻomaʻo. Hoʻohana ʻia nā mea epitaxial ʻulaʻula a uliuli paha e hana i nā LED ʻōmaʻomaʻo. Ma lalo o ke ʻano o ka haʻahaʻa haʻahaʻa o kēia manawa, no ka mea, ʻaʻohe phosphor hoʻololi nalowale, ʻoi aku ka maikaʻi o ka ʻōmaʻomaʻo LED ma mua o ka uliuli + phosphor ʻano kukui ʻōmaʻomaʻo. Ua hōʻike ʻia ua hiki i kāna hana kukui a hiki i 291Lm/W ma lalo o ke kūlana o 1mA i kēia manawa. Eia nō naʻe, ʻo ka hāʻule ʻana o ka māmā māmā o ke kukui ʻōmaʻomaʻo i hoʻokumu ʻia e ka hopena Droop ma lalo o kahi ʻoi aku ka nui. Ke piʻi aʻe ka nui o kēia manawa, hāʻule koke ka māmā māmā. I kēia manawa o 350mA, ʻo 108Lm/W ka māmā māmā. Ma lalo o ke kūlana o 1A, hāʻule ka māmā māmā. I 66Lm/W.

No III phosphines, ua lilo ka hoʻokuʻu ʻana o ka mālamalama i ka hui ʻōmaʻomaʻo i mea pale nui i ka ʻōnaehana waiwai. ʻO ka hoʻololi ʻana i ka haku mele ʻana o AlInGaP e hoʻokuʻu i ke kukui ʻōmaʻomaʻo ma kahi o ka ʻulaʻula, ʻalani a melemele paha—no ka lawa ʻole o ka palena o ka lawe lawe ma muli o ka haʻahaʻa haʻahaʻa o ka ikehu o ka ʻōnaehana mea, ka mea i kāpae ʻia ka hoʻohui hou ʻana o ka radiation.

No laila, ke ala e hoʻomaikaʻi ai i ka māmā māmā o nā LED ʻōmaʻomaʻo: ma ka ʻaoʻao hoʻokahi, e aʻo pehea e hōʻemi ai i ka hopena Droop ma lalo o nā kūlana o nā mea epitaxial e hoʻomaikaʻi ai i ka māmā; ma ka lua, e hoʻohana i ka photoluminescence huli ana o uliuli LED a me ka uliuli phosphors e emit omaomao malamalama. Hiki i kēia ʻano hana ke loaʻa i ke kukui ʻōmaʻomaʻo luminous kiʻekiʻe, hiki ke hoʻokō theoretically hiki ke hoʻokō i ka pono luminous kiʻekiʻe ma mua o ke kukui keʻokeʻo o kēia manawa. Aia ia i ke kukui ʻōmaʻomaʻo non-spontaneous. ʻAʻohe pilikia me ke kukui. ʻOi aku paha ka hopena o ke kukui ʻōmaʻomaʻo ma kēia ʻano ma mua o 340 Lm/W, akā ʻaʻole naʻe e ʻoi aku ma mua o 340 Lm/W ma hope o ka hui ʻana i ke kukui keʻokeʻo; ʻO ke kolu, e hoʻomau i ka noiʻi ʻana a loaʻa i kāu mea epitaxial ponoʻī, aia wale nō ma kēia ala, aia kahi ʻulaʻula o ka manaʻolana ma hope o ka loaʻa ʻana o ke kukui ʻōmaʻomaʻo i ʻoi aku ka kiʻekiʻe ma mua o 340 Lm/w, ʻoi aku ke kiʻekiʻe o ke kukui keʻokeʻo i hui pū ʻia e nā kala kumu ʻekolu o nā LED ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli ma mua o ka palena o ka luminous efficiency o nā kukui keʻokeʻo polū o 340 Lm / W.

3. LED Ultravioletpuʻupuʻu + ʻekolu phosphors waihoʻoluʻu mua e hoʻomāmā 

ʻO ka hemahema koʻikoʻi o nā ʻano LED keʻokeʻo ʻelua ma luna nei, ʻo ia ka hāʻawi ʻole ʻana o ka luminosity a me ka chromaticity. ʻAʻole ʻike ʻia ke kukui ultraviolet e ka maka kanaka. No laila, ma hope o ka puka ʻana o ke kukui ultraviolet i ka chip, ua hoʻopili ʻia e nā phosphors kala mua ʻekolu o ka papa encapsulation, i hoʻololi ʻia i ke kukui keʻokeʻo e ka photoluminescence o ka phosphor, a laila hoʻokuʻu ʻia i loko o ke ākea. ʻO kēia kāna pono nui loa, e like me nā kukui fluorescent kuʻuna, ʻaʻohe ona kala kala ʻole. Eia naʻe, ʻaʻole hiki ke kiʻekiʻe ke kiʻekiʻe o ka mana o ke kukui keʻokeʻo ultraviolet chip-type ma mua o ka waiwai kumu o ke kukui keʻokeʻo ʻano polū, waiho wale i ka waiwai theoretical o ke kukui keʻokeʻo RGB-type. Eia nō naʻe, ma o ka hoʻomohala ʻana i nā phosphors ʻekolu-primary kūpono no ka hoʻoulu ʻana o ka kukui ultraviolet hiki ke loaʻa i nā kukui keʻokeʻo keʻokeʻo ultraviolet e kokoke ana a ʻoi aku paha ma mua o nā LED kukui keʻokeʻo ʻelua ma luna o kēia pae. ʻO ka kokoke i ke kukui ultraviolet polū LED, hiki ke hiki ʻO ka nui o ke kukui keʻokeʻo LED o ka nalu waena a me ke ʻano ultraviolet hawewe pōkole ʻaʻole hiki.
