Ubushyuhe bw'amabara
Iyo umwirabura usanzwe ashyushye (nk'umugozi wa tungsten mu itara ryaka), ibara ry'umukara ritangira guhinduka buhoro buhoro umutuku wijimye - umutuku utukura - orange - umuhondo - umweru - ubururu uko ubushyuhe bwiyongera. Iyo ibara ryumucyo utangwa nisoko yumucyo ari kimwe nubwa mwirabura usanzwe mubushyuhe runaka, twita ubushyuhe bwuzuye bwumwirabura muricyo gihe nkubushyuhe bwamabara yinkomoko yumucyo, bugereranwa nubushyuhe bwuzuye : K.

Guhuza amabara
Guhuza kumurongo wa blackbody byitwa ubushyuhe bwamabara, kandi hariho imirongo ihamye; ihuriro hanze yumwirabura (hafi yumukara wa trayektori) bita thebifitanye isanoubushyuhe bwamabara, nabwo bwitwa ubushyuhe bwamabara. Kurugero, Kuri Ibara Ubushyuhe bwa6250k, ibara rihuza x = 0.3176 y = 0.3275. Ubushyuhe, kuva hasi kugeza hejuru, ingingo zose zubushyuhe bwibara zikora umurongo (umurongo), ibyo bita "blackbody color temperature trajectory".
Nyamara, ubushyuhe bwamabara bukunze kuvugwa ubu mubyukuri "bifitanye isano nubushyuhe bwamabara" (CCT); "Ubushyuhe bwamabara" nabwo bukoreshwa kumwanya (guhuza) utari munzira ariko utari kure, kandi ubushyuhe bwibara ryibara ryagaciro nigiciro cyikintu cyegereye inzira. Muri ubu buryo, kubushyuhe bumwe bwamabara, hari ingingo nyinshi
hanze yumurongo, kandi imirongo ihuza izi ngingo yitwa "isotherms"; Nukuvuga, imirongo yose kuriyi murongo ifite ubushyuhe bumwe bwamabara. Tanga ifoto. Imibare iri ku gishushanyo yerekana "isotherm", umurongo ni "inzira ya blackbody", naho ellipse ni ihuriro ryurwegoItara 6500kbiteganijwe na Leta.

Guhuza Chromaticity ni ihuriro ryamabara. Noneho bikunze gukoreshwa ibara rihuza, umurongo utambitse ni x, na vertical axis ni y. Hamwe na chromaticity ihuza ibikorwa, ingingo irashobora kugenwa kumurongo wa chromaticity. Iyi ngingo yerekana neza ibara ryaka. Nukuvuga, chromaticity ihuza neza ibara neza. Kuberako guhuza ibikorwa bya chromaticity bifite imibare ibiri kandi ntibisanzwe, abantu bakunda gukoresha ubushyuhe bwamabara kugirango bagaragaze neza ibara ryaka ryumucyo. Mubyukuri, ubushyuhe bwamabara bubarwa binyuze muri chromaticity coordinate, kandi ubushyuhe bwamabara ntibushobora kuboneka hatabayeho guhuza ibikorwa bya chromaticity. Niba ifite ibara ryijimye cyane, nkicyatsi, ubururu, nibindi urashobora kubara "uburebure bwumurongo wingenzi" na "ibara ryera" ukoresheje chromaticity guhuza kugirango ugaragaze neza ibara. Ku matara azigama ingufu, leta yashyizeho ibikurikira bya chromaticity ihuza ibisabwa, kandi agaciro ko gutandukana kari munsi ya 5SDCM.

Mu mabara atatu yibanze, umutuku gusa ufite ubushyuhe bwamabara agera kuri 900K, mugihe andi mabara nta gitekerezo cyubushyuhe bwamabara. Urugero: icyuma ntikizahinduka icyatsi cyangwa ubururu nubwo cyaba gishyushye gute. Ubushyuhe bwamabara bukoreshwa mugushushanya ibara ryumucyo (hafi yera). Ubushyuhe buke bwamabara, bwera numuhondo, bita tone ashyushye; Ubushyuhe bwo hejuru, bwera nubururu, bwitwa tone ubukonje. Itara ry'icyatsi ntirishobora kugaragazwa n'ubushyuhe bw'amabara; Itara ry'ubururu naryo ntabwo rifite ubushyuhe bwamabara.
Turashobora kubona ko itandukaniro rya chromaticity rihuza kumpande zombi za isotherm iragaragara, ni ukuvuga, ubushyuhe bwamabara bufitanye isano ni bumwe (ni ukuvuga kuri isotherm), ariko itandukaniro ryamabara yumucyo waryo rishobora no kubonwa nijisho ryumuntu . Iyo hari itandukaniro runaka mubushyuhe bwamabara afitanye isano, itandukaniro ryamabara rishobora kubaho. Mubisanzwe, abakora LED bashyira LED ibara ryubushyuhe bujyanye nibisabwa mubipimo bihuye. Ntakibazo gihari mugukoresha ahantu rusange hacana amatara, ariko mugihe cyo gusaba hamwe nibisabwa bitandukanya ibara risabwa, ibicuruzwa bya LED bifite ibara ryiza ryiza bigomba guhitamo kubyara umusaruro.
