He aha te whakakotahitanga tae me te SDMC?

Manawanui Tae: He ariā e pā tata ana ki te pāmahana tae. I te tuatahi i whakaarohia tēnei ariā e Kodak i roto i te umanga, ko te ariā Piritana ko te Paerewa Ine o te Taurite Tae, e kiia ana ko te SDCM. Ko te rerekētanga i waenga i te uara i tatauhia e te rorohiko me te uara paerewa o te pūtake mārama e whai ana. Arā, he tohutoro motuhake te manawanui tae ki te pūtake mārama e whai ana.

Ka tātarihia e te taputapu whakaahua-ira te whānuitanga pāmahana tae o te pūtake mārama i inehia, kātahi ka whakatauhia te uara pāmahana tae paerewa. Ina rite te pāmahana tae, ka whakatauhia te uara o tōna taunga tae xy me te rerekētanga i waenganui i a ia me te pūtake mārama paerewa. Ko te nui ake o te ātete tae, ko te nui ake o te rerekētanga tae. Ko te waeine o tēnei ātete tae ko te SDCM. Ka whakatauhia e te ātete karaima te rerekētanga o te tae mārama o tētahi puranga rama. Ko te whānuitanga ātete tae ka whakaaturia i runga i te kauwhata hei porowhita kaua hei porowhita. He porowhita whakauru ngā taputapu ngaio whānui hei ine i ngā raraunga motuhake, ā, kei ētahi wheketere takai LED me ngā wheketere rama he taputapu ngaio e pā ana.

Kei te pokapū hokohoko me te wheketere tā mātou ake mīhini whakamātautau, ka whakamatautauria ia tauira me te wāhanga tuatahi o te hanga (tae atu ki te COB LED STRIP, NEON FLEX, SMD LED STRIP me te RGB LED STRIP), ā, ka mahia te hanga papatipu i muri i te paahitanga o te whakamātautau. Ka whakakākahuhia hoki e mātou ngā pirepire rama, ka taea te whakahaere pai i roto i te ipu o te rama rīpene LED.

Nā te rerekētanga o te tae e puta mai ana i ngā rama LED mā, he inenga watea hei whakaatu i te whānuitanga o te rerekētanga tae i roto i tētahi puranga rama LED ko te maha o ngā takahanga porowhita SDCM (MacAdam) e taka ai ngā rama LED. Mena ka taka katoa ngā rama LED ki roto i te 1 SDCM (he "porowhita MacAdam 1-taahiraa" rānei), e kore te nuinga o te tangata e kite i tētahi rerekētanga o te tae. Mena he rerekētanga tae ka toro atu te rerekētanga o te tae ki tētahi rohe e rua te rahi (2 SDCM he porowhita MacAdam 2-taahiraa rānei), ka tīmata koe ki te kite i ētahi rerekētanga tae. He pai ake te porowhita MacAdam 2-taahiraa i te rohe 3-taahiraa, ā, pērā tonu.

Heoi, he maha ngā āhuatanga e pā ana ki te manawanui tae, pērā i ngā take mō te maramara LED, te take mō te ōwehenga o te paura phosphor, te take mō te huringa o te iahiko taraiwa, me te hanganga o te rama ka pā hoki ki te pāmahana tae. Ko te take mō te hekenga o te kanapa me te tere o te koroheketanga o te pūtake mārama, ka puta hoki te nekehanga pāmahana tae o te LED i te wā e whakamārama ana, nō reira ka whakaarohia e ētahi rama te pāmahana tae me te ine i te pāmahana tae i roto i te āhua mārama i te wā tūturu. Ko ngā paerewa manawanui tae ko ngā paerewa o Amerika Te Raki, ngā paerewa IEC, ngā paerewa Pākehā me ētahi atu. Ko tā mātou whakaritenga whānui mō te manawanui tae LED ko te 5SDCM. I roto i tēnei awhe, ka taea e ō tātou kanohi te wehewehe i te aberration chromatic.
