LED Ubumenyi Igice cya 2: Ni ayahe mabara LED ifite?

LED yera

Itandukaniro ryinshi rikorwa mugihe cyo gukora amatara ya LED yatoranijwe.Agace ka chromatic kitwa 'bin' ni kuringaniza kumurongo wa BBL.Guhuza amabara biterwa nubumenyi-bwububiko nubuziranenge.Guhitamo binini bisobanura ubuziranenge, ariko kandi nibiciro biri hejuru.

MacAdam Ellipses

Reba ahantu ku gishushanyo cya chromaticity kirimo amabara yose atamenyekana, kugeza ijisho ryabantu basanzwe, uhereye ibara riri hagati ya ellipse.Ibice bya ellipse byerekana itandukaniro rigaragara gusa rya chromaticity.MacAdam yerekana itandukaniro riri hagati ya ellips ebyiri zoroheje, zisobanurwa nkizifite 'intambwe' zerekana gutandukana kwamabara.Mubisabwa aho isoko yumucyo igaragara, iyi phenomenon igomba kwitabwaho kuko ellipse yintambwe 3 ifite ibara rito ryo gutandukana kurenza intambwe 5.

LED yamabara

Igishushanyo mbonera cya CIE gishingiye ku miterere yihariye ya physiologique yijisho ryumuntu kugirango isuzume amabara uyigabanyijemo ibice bitatu byingenzi bya chromatic (inzira yamabara atatu): umutuku, ubururu nicyatsi, ushyizwe hejuru yumurongo wigishushanyo.Igishushanyo cya CIE gishobora kuboneka kubara x na y kuri buri bara ryiza.Ibara ryerekana amabara (cyangwa amabara meza) urashobora kuboneka kumurongo wa kontour, mugihe amabara imbere mubishushanyo ari amabara nyayo.Twabibutsa ko ibara ryera (nandi mabara mugace rwagati - amabara ya acromatic cyangwa igicucu cyumuhondo) ntabwo ari amabara meza, kandi ntashobora guhuzwa nuburebure bwihariye.
