1. Maramara kikorangi-LED + momo phosphor kōwhai-kakariki tae atu ki te momo phosphor maha-tae

 Ka mimiti te paparanga whūpōro kōwhai-kakariki i tētahi wāhanga o temārama kikorangio te maramara LED hei whakaputa i te photoluminescence, ā, ko te wāhanga kē atu o te mārama kikorangi mai i te maramara LED ka tukuna atu i te paparanga phosphor ka hanumi ki te mārama kōwhai-kakariki e tukuna ana e te phosphor i ngā wāhi rerekē o te wāhi, ā, ka konatunatua te mārama whero, kakariki me te kikorangi hei hanga mārama mā; Mā tēnei ara, ko te uara ariā teitei rawa atu o te whai huatanga tahuritanga photoluminescence phosphor, ko tētahi o ngā whai huatanga kuantum o waho, e kore e neke ake i te 75%; ā, ko te tere tango mārama teitei rawa atu mai i te maramara ka taea anake te eke ki te 70%, nō reira i roto i te ariā, ko te mārama kikorangi mā te mārama LED teitei rawa atu e kore e neke ake i te 340 Lm/W, ā, i eke te CREE ki te 303Lm/W i ngā tau kua hipa. Mena he tika ngā hua o te whakamātautau, he mea tika kia whakanuia.

2. Te whakakotahitanga o te whero, te kakariki me te kikorangiRGB LEDkei roto i te momo te momo RGBW-LED, me ētahi atu.

 Ka honoa ngā rama-whakaputa rama e toru o te R-LED (whero) + G-LED (kakariki) + B-LED (kikorangi) ki te taha, ā, ka whakaranua tika ngā tae matua e toru o te whero, te kakariki me te kikorangi ki te wāhi hei hanga rama mā. Hei whakaputa i te rama mā tino whai hua i tēnei ara, tuatahi, me tino whai hua ngā rama LED o ngā tae rerekē, inā koa ngā rama kakariki, e kitea ana i te "rama mā pūngao ōrite" e 69% te nui o te rama kakariki. I tēnei wā, he tino teitei te whai huatanga rama o ngā rama kikorangi me te whero, me te nui ake o te whai huatanga matū ā-roto i te 90% me te 95%, ia, engari kei muri rawa te whai huatanga matū ā-roto o ngā rama kakariki. Ko tēnei āhuatanga o te iti o te whai huatanga rama kakariki o ngā rama GaN e kiia ana ko te "āputa rama kakariki." Ko te take matua ko te korenga o ngā rama kakariki i kitea ā rātou ake rauemi epitaxial. He iti te whai huatanga o ngā rauemi raupapa nitride arsenic phosphorous i roto i te whānuitanga kōwhai-kakariki. Ka whakamahia ngā rauemi epitaxial whero, kikorangi rānei hei hanga rama kakariki. I raro i te āhua o te iti o te kiato o te iahiko, nā te mea kāore he mate o te tahuritanga o te whākawa, he nui ake te pai o te kanapa o te LED matomato i te rama matomato kikorangi me te whākawa. E ai ki ngā pūrongo, ka eke tōna pai o te kanapa ki te 291Lm/W i raro i te āhua o te iahiko 1mA. Heoi, he nui te hekenga o te pai o te kanapa o te rama matomato i puta mai i te pānga o te whakaheke i raro i te iahiko nui ake. Ina piki ake te kiato o te iahiko, ka tere te heke o te pai o te kanapa. I te iahiko 350mA, ko te pai o te kanapa he 108Lm/W. I raro i te āhua o te 1A, ka heke te pai o te kanapa. Ki te 66Lm/W.

Mō ngā phosphine III, kua noho te tukunga o te mārama ki te awhi matomato hei arai matua ki te pūnaha rauemi. Ko te whakarerekētanga o te hanganga o AlInGaP kia tukuna he mārama matomato hei utu mō te whero, te karaka, te kōwhai rānei—ko te take o te korenga o te herenga kawe nā te iti o te āputa pūngao o te pūnaha rauemi, e kore ai e taea te whakakotahitanga irahiko whai hua.

Nō reira, ko te huarahi hei whakapai ake i te whai huatanga o te mārama o ngā LED matomato: i tētahi taha, akohia me pēhea te whakaiti i te pānga Droop i raro i ngā āhuatanga o ngā rauemi epitaxial o nāianei hei whakapai ake i te whai huatanga o te mārama; i tētahi taha tuarua, whakamahia te hurihanga photoluminescence o ngā LED kikorangi me ngā phosphor matomato hei tuku i te mārama matomato. Ka taea e tēnei tikanga te whiwhi i te mārama matomato whai huatanga teitei, e taea ai te whakatutuki i te whai huatanga teitei ake i te mārama mā o nāianei. Nō te mārama matomato kore-tūturu. Kāore he raruraru ki te mārama. Ko te pānga mārama matomato i whiwhihia e tēnei tikanga ka nui ake i te 340 Lm/W, engari kāore tonu e neke ake i te 340 Lm/W i muri i te whakakotahitanga o te mārama mā; tuatoru, haere tonu ki te rangahau me te kimi i tāu ake rauemi epitaxial, engari i tēnei ara, he iti noa te tumanako i muri i te whiwhi i te mārama matomato he nui ake i te 340 Lm/w, ko te mārama mā i honoa e ngā tae matua e toru o ngā LED whero, matomato me te kikorangi ka teitei ake i te rohe whai huatanga o te mārama o ngā LED mā kikorangi maramara o te 340 Lm/W.

3. Rama hihi-wheromaramara + e toru ngā tae matua o te whēkura e tuku ana i te mārama 

Ko te ngoikoretanga matua o ngā momo rama LED mā e rua i runga ake nei ko te tohatoha koretake o te kanapa me te tae o te wāhi. Kāore e kitea te mārama ultraviolet e te kanohi tangata. Nō reira, i muri i te putanga o te mārama ultraviolet i te maramara, ka mimitihia e ngā phosphor tae matua e toru o te paparanga encapsulation, ka hurihia hei mārama mā e te photoluminescence o te phosphor, kātahi ka tukuna ki te wāhi. Koinei tōna painga nui, pērā i ngā rama fluorescent tuku iho, kāore he koretake o te tae wāhi. Heoi, ko te whai huatanga māramatanga ariā o te rama LED mārama momo maramara ultraviolet kāore e taea te teitei ake i te uara ariā o te mārama momo maramara kikorangi, me te uara ariā o te mārama momo RGB. Heoi, mā te whanaketanga o ngā phosphor matua-toru whai huatanga teitei e tika ana mō te whakaoho rama ultraviolet anake ka taea te whiwhi rama LED mārama ultraviolet e tata ana, e teitei ake rānei i ngā rama LED mārama e rua i runga ake nei i tēnei wā. Ko te tata atu ki te rama LED mārama ultraviolet kikorangi, ko te tūponotanga Ko te nui ake o te rama LED mārama momo ngaru waenga me te ngaru poto ultraviolet kāore e taea.
