Ruzivo rwe LED Chikamu 2: Ndeapi mavara ane ma LED?

White LED

Misiyano yakati wandei inoitwa panguva yekugadzirwa kwemarambi e LED akasarudzwa.Nzvimbo dzechromatic dzinodaidzwa kuti 'bin' dzakachinjika makongiri emutsetse weBBL.Kufanana kwemavara kunoenderana nekuziva kwemugadziri uye maitiro emhando.Sarudzo yakakura inoreva mhando yepamusoro, asiwo mitengo yakakwira.

MacAdam Ellipses

Tarisa nzvimbo iri pa chromaticity diagram ine mavara ese asingaonekwe, kune avhareji yeziso remunhu, kubva paruvara rwepakati pe ellipse.Iyo contour ye ellipse inomiririra mutsauko unooneka wechromaticity.MacAdam inoratidza mutsauko uripo pakati pemavara maviri emwenje kuburikidza ne ellipses, ayo anotsanangurwa seane 'matanho' anoratidza chiyero kutsauka kwemavara.Mumashandisirwo ari kuoneka masosi emwenje, chiitiko ichi chinofanira kuverengerwa nekuti 3-nhanho ellipse ine yakaderera ruvara kusiyana pane nhanho 5.

Colored LEDs

Iyo CIE chromatic dhayagiramu yakavakirwa pachimiro chechimiro cheziso remunhu kuongorora mavara nekuatyora muzvikamu zvitatu zvakakosha zvechromatic zvikamu (matatu-mavara maitiro): tsvuku, bhuruu uye girinhi, yakaiswa pamusoro peiyo dhizaini curve.Iyo CIE chromatic diagraph inogona kuwanikwa nekuverenga x uye y kune yega yega ruvara rwakachena.Iwo spectrum mavara (kana akachena mavara) anogona kuwanikwa pane contour curve, nepo mavara ari mukati medhayagiramu ari chaiwo mavara.Zvinofanira kucherechedzwa kuti ruvara ruchena (uye mamwe mavara munzvimbo yepakati - achromatic mavara kana mumvuri we grey) haasi mavara akachena, uye haagoni kubatanidzwa kune yakatarwa wavelength.
