Qaphela ukukhanya kwe-RGB kweUkuhlaziywa kwesikhumba

I-RGB yenzelwe kusuka emgabeni we-Colour Luminescence. Ngokwemigomo kaLayman, indlela yayo yokuxuba imibala injengezibani ezibomvu, eziluhlaza okotshani, kanye nama-Blue. Lapho amalambu awo ancike komunye nomunye, imibala ixubene, kepha ukukhanya kulingana nesamba sokukhanya kwalaba bobabili, okuxutshwe ngokwengeziwe ukukhula okuphezulu, okungukuthi, ukuxuba okungezelelweyo.

Ukuze uthole amalambu abomvu, aluhlaza okwesibhakabhaka, indawo ekhanyayo kakhulu yemibala emithathu emithathu imhlophe, kanye nezimpawu zokuxuba okungezelelwayo: Isimangaliso esithe xaxa, esiqhakazayo.

Ngayinye yalezi ziteshi ezintathu zombala, ezibomvu, eziluhlaza, eziluhlaza okwesibhakabhaka, zihlukaniswe ngamazinga angama-256 okukhanya. Ku-0, "ukukhanya" kubuthakathaka - kuvaliwe, futhi ngo-255, "ukukhanya" kukhanya kakhulu. Lapho amanani amathathu anemibala emithathu afanayo, amathoni ampunga anamanani ahlukene we-greyscale akhiqizwa, okungukuthi, lapho i-grayscale emithathu yombala ingu-0, kuyinto emnyama kakhulu; Lapho i-graysale emibala emithathu ingu-255, iyizwi elimhlophe elikhanyayo kakhulu.

Imibala ye-RGB ibizwa ngemibala engezansi ngoba udala okumhlophe ngokungeza r, g, kanye no-B ndawonye (okungukuthi, konke ukukhanya kuboniswa emuva esweni). Imibala engezansi isetshenziswa ekukhanyiseni, kuthelevishini nakwekhompyutha. Isibonelo, kukhombisa umbala wokukhiqiza ngokukhanyisa ukukhanya kusuka kubomvu, oluhlaza okotshani, kanye nama-phosphors aluhlaza okwesibhakabhaka. Iningi le-spectrum elibonakalayo lingavezwa njengengxube yombala obomvu, oluhlaza okotshani, nohlaza okwesibhakabhaka (RGB) ngokulingana okuhlukahlukene kanye namandla. Lapho le mibala inqamula, i-cyan, i-magenta nephuzi kukhiqizwa.

Amalambu we-RGB akhiwa yimibala emithathu eyinhloko ehlanganiswe ukwakha isithombe. Ngaphezu kwalokho, kukhona ne-LED eluhlaza okwesibhakabhaka enama-phosphors aphuzi, kanye ne-ultraviolet leds nge-RGB phosphors. Ngokuvamile, bobabili banezimiso zabo zokucabanga.

Kokubili ukukhanya okumhlophe kwaholela ku-RGB LED enomgomo ofanayo, futhi bobabili banethemba lokuthola umphumela wokukhanya okumhlophe, kepha umuntu wethulwa ngokuqondile njengokukhanya okumhlophe, kanti omunye kwakheka ngokuxuba okubomvu, okuluhlaza okotshani nohlaza okwesibhakabhaka.
