Mumyaka yashize, hamwe no gukoresha cyane leta-ikomeyeLED yamurika, abantu benshi nabo bagerageza gusesengura uburyo bugoye no kugenzura tekinoroji ya LED.

Ibyerekeye Kuvanga Inyongera

LED amatara yumwuzurekoresha urumuri rwinshi kugirango ubone amabara nimbaraga zitandukanye. Ku nganda zimurika imyidagaduro, kongeramo no kuvanga amabara bimaze kuba clich é. Kumyaka myinshi, abimenyereza bakoresheje amatara hamwe nayunguruzo rwamabara kugirango bashushanye agace kamwe kuri kanopi, ntibyoroshye kugenzura. Itara rifite amasoko atatu ya MR16 yumucyo, buri kimwe gifite umutuku, icyatsi, nubururu muyunguruzi. Mu minsi ya mbere, ubu bwoko bwamatara bwari bufite imiyoboro itatu ya DMX512 kandi nta miyoboro yigenga yo kugenzura imbaraga. Biragoye rero kugumana ibara ridahinduka mugihe cyo gucura. Mubisanzwe, porogaramu yerekana urumuri rwa mudasobwa nayo ishyiraho "itara rihindura ibara" kugirango byoroshye kuzimya amatara. Nibyo, hari inzira nziza, kandi ntabwo nzabashyira kurutonde hano.

Kugenzura no gusobanura amabara

Niba umukoresha adakoresheje indangagaciro za DMA kugirango agenzure urumuri rwubwenge, ariko akoresha uburyo bumwe na bumwe bwo kugenzura, agaciro gakomeye gashobora gukoreshwa. Nubwo uwabikoze yerekana neza ko amatara akoresha imiyoboro itatu ya DMA, uburyo bwo kugenzura ibintu burashobora kugenwa uburyo bune bwo kugenzura: agaciro kinshi nibipimo bitatu byamabara.

Ibipimo bitatu byamabara "aho kuba umutuku, icyatsi, nubururu, kuko RGB nuburyo bumwe gusa bwo gusobanura amabara. Ubundi buryo bwo kubisobanura ni hue, kwiyuzuzamo, no kumurika HSL (bamwe babyita ubukana cyangwa umucyo, aho kuba umucyo). Ubundi busobanuro ni hue, kwiyuzuzamo, nagaciro HSV. Agaciro, kazwi kandi nkumucyo, bisa na Luminance. Ariko, hari itandukaniro rikomeye mubisobanuro byuzuye kuri HSL na HSV. Kubworoshye, muriki kiganiro, umwanditsi asobanura hue nkibara no kwiyuzuza nkubunini bwamabara. Niba 'L' yashyizwe kuri 100%, ni umweru, 0% ni umukara, na 50% ya L ni ibara ryiza rifite ubwuzure bwa 100%. Kuri 'V', O% ni umukara na 100% birakomeye, kandi agaciro kuzuye kagomba kuzuza itandukaniro.

Ubundi buryo bwiza bwo gusobanura ni CMY, nuburyo butatu bwibanze bwamabara akoresha kuvanga amabara avanze. Niba urumuri rwera rusohotse mbere, noneho amabara abiri yungurura arashobora gukoreshwa kugirango abone umutuku: magenta n'umuhondo; Bakuraho icyatsi nubururu ibice byurumuri rwera bitandukanye. Mubisanzwe,LED itara rihindura amatarantukoreshe kuvanga amabara avanze, ariko ubu nuburyo bwiza bwo gusobanura amabara.

Mubyigisho, mugihe ugenzura LED, bigomba gushoboka guhindura ubukana na RGB, CMY Imwe muri HSL cyangwa HSV (hamwe nibitandukaniro hagati yabo).

Ibyerekeye kuvanga amabara ya LED

Ijisho ryumuntu rishobora kumenya urumuri rufite uburebure buri hagati ya 390 nm na 700 nm. Ibikoresho bya LED byambere byakoresheje gusa umutuku (hafi 630 nm), icyatsi (hafi 540 nm), nubururu (hafi 470 nm) LED. Aya mabara atatu ntashobora kuvangwa kugirango atange amabara yose agaragara mumaso yumuntu
