Kwiminyaka yakutshanje, ngokusetyenziswa ngokubanzi kwe-solid-stateIzibane ze-LED, abantu abaninzi bazama ukuhlalutya ubunzima kunye neendlela zokulawula iteknoloji yombala we-LED.

Malunga noDibaniso oloNgezelelweyo

Izibane zezikhukula ze-LEDsebenzisa imithombo yokukhanya emininzi ukufumana imibala eyahlukeneyo kunye nobunzulu. Kumashishini okukhanyisa ukuzonwabisa, ukongeza kunye nokuxuba imibala sele i-clich é. Kangangeminyaka emininzi, iingcali ziye zasebenzisa izibane ezineefilitha zombala ukwenza iprojekthi indawo efanayo kwicanopy, ekungekho lula ukuyilawula. Isibane esinemithombo yokukhanya emithathu ye-MR16, nganye inezihluzo ezibomvu, eziluhlaza, nezibhlowu. Ngeentsuku zokuqala, olu hlobo lwesibane lwaluneendlela ezintathu zokulawula i-DMX512 kwaye akukho ziteshi zokulawula amandla ezizimeleyo. Ngoko ke kunzima ukugcina umbala ungatshintshanga ngexesha lenkqubo yobumnyama. Ngokwesiqhelo, abadwelisi benkqubo bokukhanya kwekhompyuter baseka "ukukhanya kokutshintsha kombala" ukucima izibane ngokulula. Ewe, kukho iindlela ezingcono, kwaye andiyi kuzidwelisa zonke apha.

Ulawulo kunye neNkcazo yeMibala

Ukuba umsebenzisi akasebenzisi ixabiso elicocekileyo le-DMA ukulawula izibane ezikrelekrele, kodwa usebenzisa indlela yokulawula engabonakaliyo, ixabiso lenyani lingasetyenziswa. Nokuba umenzi uchaza ukuba izibane zokukhanyisa zisebenzisa amajelo amathathu e-DMA, indlela yokulawula i-abstract isenokwabelwa izibambo ezine zokulawula: ixabiso lokuqina kunye neeparamitha ezintathu zombala.

Iiparamitha ezintathu zemibala “endaweni yobomvu, eluhlaza, nobhlowu, njengoko i-RGB yindlela enye yokuchaza imibala. Enye indlela yokuyichaza yi-hue, saturation, kunye ne-luminance HSL (abanye bayibiza ngokuba bunzulu okanye ukukhanya, kunokukhanya). Enye inkcazo yi-hue, saturation, kunye nexabiso le-HSV. Ixabiso, elikwabizwa ngokuba kukuqaqamba, liyafana neLuminance. Nangona kunjalo, kukho umahluko omkhulu kwinkcazo yokugcwala phakathi kwe-HSL kunye ne-HSV. Ukuze kube lula, kweli nqaku, umbhali uchaza i-hue njengombala kunye nokuzaliswa njengobungakanani bombala. Ukuba 'L' imiselwe ku-100%, imhlophe, i-0% imnyama, kwaye i-50% ye-L ngumbala osulungekileyo onokugcwala kwe-100%. Ku-'V', i-O% imnyama kwaye i-100% iqinile, kwaye ixabiso lokugcwalisa kufuneka lenze umahluko.

Enye indlela yenkcazo esebenzayo yiCMY, eyinkqubo yombala emithathu ephambili esebenzisa ukuxuba kombala othatyathiweyo. Ukuba ukukhanya okumhlophe kukhishwa ekuqaleni, ngoko izihluzi zemibala ezimbini zingasetyenziselwa ukufumana obomvu: i-magenta kunye nephuzi; Basusa amacandelo aluhlaza kunye nohlaza okwesibhakabhaka ekukhanyeni okumhlophe ngokwahlukileyo. Ngesiqhelo,Izibane zokutshintsha umbala we-LEDSukusebenzisa ukuxuba umbala othatyathiweyo, kodwa oku kuseyindlela esebenzayo yokuchaza imibala.

Kwithiyori, xa ulawula ii-LED, kufuneka kwenzeke ukulungelelanisa ukuqina kunye ne-RGB, i-CMY enye ye-HSL okanye i-HSV (kunye nokungafani phakathi kwabo).

Malunga nokuxuba umbala we-LED

Iliso lomntu liyakwazi ukubona ukukhanya ngobude obusuka kwi-390 nm ukuya kuma-700 nm. Iimpawu zokuqala ze-LED zisebenzise kuphela obomvu (malunga ne-630 nm), eluhlaza (malunga ne-540 nm), kunye ne-blue (malunga ne-470 nm) ii-LED. Le mibala mithathu ayinakuxutywa ukuvelisa wonke umbala obonakalayo emehlweni abantu
