M'zaka zaposachedwapa, ndi ambiri ntchito olimba bomaZowunikira za LED, anthu ambiri akuyeseranso kusanthula zovuta ndi njira zowongolera zaukadaulo wamtundu wa LED.

Za Zowonjezera Zosakaniza

Nyali za kusefukira kwa LEDgwiritsani ntchito magwero owunikira angapo kuti mupeze mitundu yosiyanasiyana komanso mphamvu.Kwa makampani owunikira zosangalatsa, kuwonjezera ndi kusakaniza mitundu kale ndi clich é.Kwa zaka zambiri, madokotala akhala akugwiritsa ntchito nyali zokhala ndi zosefera zamitundu kuti ziwonetse malo omwewo padenga, zomwe ndizovuta kuziwongolera.Kuwala kokhala ndi zowunikira zitatu za MR16, iliyonse ili ndi zosefera zofiira, zobiriwira, ndi zabuluu.M'masiku oyambirira, nyali yamtunduwu inali ndi njira zitatu zowongolera za DMX512 ndipo palibe njira zodziyimira pawokha.Choncho zimakhala zovuta kusunga mtundu wosasinthika panthawi ya dimming.Nthawi zambiri, opanga mapulogalamu owunikira pakompyuta amakhazikitsanso "kusintha kowala kowala" kuti azimitse magetsi mosavuta.Inde, pali njira zabwinoko, ndipo sindizilemba zonse apa.

Kulamulira ndi Tanthauzo la Mitundu

Ngati wogwiritsa ntchito sagwiritsa ntchito mfundo za DMA kuti aziwongolera zowunikira zanzeru, koma akugwiritsa ntchito njira yodziwiratu, mtengo wamphamvu ungagwiritsidwe ntchito.Ngakhale wopanga anganene kuti zowunikira zimagwiritsa ntchito ma tchanelo atatu a DMA, njira yowongolera ingathe kuperekedwabe zogwirira zinayi kuti ziwongolere: kuchuluka kwamphamvu ndi magawo atatu amitundu.

Mitundu itatu yamitundu "m'malo mofiira, yobiriwira, ndi yabuluu, popeza RGB ndi njira imodzi yokha yofotokozera mitundu.Njira ina yofotokozera ndi mtundu, machulukitsidwe, ndi kuwala kwa HSL (ena amachitcha kuti intensity kapena lightness, osati kuwala).Kufotokozera kwina ndi mtundu, machulukitsidwe, ndi mtengo wa HSV.Mtengo, womwe umadziwikanso kuti kuwala, ndi wofanana ndi Kuwala.Komabe, pali kusiyana kwakukulu pakutanthauzira kwa machulukitsidwe pakati pa HSL ndi HSV.Kuti zikhale zosavuta, m'nkhaniyi, wolemba akutanthauzira hue monga mtundu ndi machulukidwe monga kuchuluka kwa mtundu.Ngati 'L' akhazikitsidwa ku 100%, ndi yoyera, 0% ndi yakuda, ndipo 50% ya L ndi mtundu weniweni wokhala ndi machulukitsidwe a 100%.Kwa 'V', O% ndi yakuda ndipo 100% ndi yolimba, ndipo mtengo wa machulukitsidwe uyenera kupanga kusiyana kwake.

Njira ina yofotokozera bwino ndi CMY, yomwe ndi mitundu itatu yoyambirira yamitundu yomwe imagwiritsa ntchito kusakaniza kwamitundu yochotsa.Ngati kuwala koyera kumatulutsidwa poyamba, ndiye kuti zosefera ziwiri zamitundu zitha kugwiritsidwa ntchito kupeza zofiira: magenta ndi chikasu;Amachotsa zigawo zobiriwira ndi zabuluu kuchokera ku kuwala koyera mosiyana.Nthawi zambiri,Nyali zosintha mtundu wa LEDmusagwiritse ntchito mitundu yosakanikirana, koma iyi ndi njira yabwino yofotokozera mitundu.

Mwachidziwitso, poyang'anira ma LED, ziyenera kukhala zotheka kusintha mphamvu ndi RGB, CMY One ya HSL kapena HSV (ndi kusiyana pakati pawo).

Za kusanganikirana kwa mtundu wa LED

Diso la munthu limatha kuzindikira kuwala ndi kutalika kwa mafunde kuyambira 390 nm mpaka 700 nm.Ma LED oyambilira amangogwiritsa ntchito zofiira (pafupifupi 630 nm), zobiriwira (pafupifupi 540 nm), ndi ma LED a buluu (pafupifupi 470 nm).Mitundu itatu imeneyi siingathe kusakanikirana kuti ipange mtundu uliwonse wooneka ndi maso
