Qaphela ukukhanya kwe-RGB yeUmhlalutyi wolusu
I-RGB yenzelwe ukusuka kumgaqo wombala we-luminescence. Ngokwemigaqo ye-layman, indlela yayo yokuxuba imibala ifana nezibane ezibomvu, eziluhlaza kunye neziluhlaza. Xa izibane zazo ziwelana, imibala ixutywe, kodwa ukukhanya kufana ne-sum of the brightness of the two, the more mixed the high lightness, that is, additive mixing.
Kwindawo ephezulu yezibane ezibomvu, eziluhlaza kunye neziluhlaza okwesibhakabhaka, eyona ndawo iqaqambileyo yombala wemibala emithathu imhlophe, kunye neempawu zokudibanisa okongeziweyo: kokukhona indawo ephezulu, iqaqambile.
Ijelo ngalinye kula mathathu anemibala, obomvu, oluhlaza, nobhlowu, lahlulwe ngokwamanqanaba angama-256 okukhanya. Kwi-0, "ukukhanya" kolona buthathaka - lucinyiwe, kwaye kwi-255, "ukukhanya" kukhanya kakhulu. Xa amaxabiso anemibala emithathu engwevu afanayo, iithowuni ezingwevu ezinamaxabiso ahlukeneyo angwevu ziyenziwa, oko kukuthi, xa umbala ongwevu wemibala emithathu yonke ingu-0, yeyona toni emnyama emnyama; xa umbala ongwevu onemibala emithathu ungama-255, yeyona toni imhlophe eqaqambileyo.
Imibala ye-RGB ibizwa ngokuba yimibala eyongezayo kuba udala mhlophe ngokudibanisa i-R, G, kunye no-B kunye (oko kukuthi, konke ukukhanya kubonakaliswa ngasemva esweni). Imibala eyongezelelweyo isetyenziselwa ukukhanyisa, umabonwakude kunye neemonitha zekhompyutheni. Umzekelo, iziboniso zivelisa umbala ngokukhupha ukukhanya kubomvu, eluhlaza, kunye ne-phosphors eluhlaza. Ubuninzi be-spectrum ebonakalayo inokubonakaliswa njengomxube obomvu, oluhlaza, kunye nohlaza okwesibhakabhaka (RGB) ukukhanya kwimilinganiselo eyahlukeneyo kunye nokuqina. Xa le mibala idibana, kuvela i-cyan, i-magenta, kunye netyheli.
Izibane zeRGB zenziwe ngemibala emithathu ephambili edityanisiweyo ukwenza umfanekiso. Ukongeza, kukwakho nee-LED eziluhlaza ezinephosphors ezityheli, kunye nee-ultraviolet ze-LED ezine-RGB phosphors. Ngokuqhelekileyo, bobabini banemigaqo yabo yokucinga.
Zombini ukukhanya okumhlophe kwe-LED kunye ne-RGB LED banenjongo efanayo, kwaye bobabini banethemba lokuphumeza umphumo wokukhanya okumhlophe, kodwa enye iboniswa ngokuthe ngqo njengokukhanya okumhlophe, kwaye enye yenziwa ngokuxuba obomvu, obuluhlaza kunye nohlaza okwesibhakabhaka.
