LED Kev Paub Txog Ntu 2: Cov xim dab tsi LEDs muaj?

Dawb LED

Ntau qhov sib txawv yog ua thaum lub sij hawm tsim khoom ntawm LED teeb xaiv.Cov cheeb tsam chromatic hu ua 'bin' yog kab rov tav contours raws BBL kab.Xim uniformity nyob ntawm tus neeg tsim khoom paub txog thiab cov qauv zoo.Ib qho kev xaiv loj dua txhais tau tias zoo dua, tab sis kuj yog tus nqi siab dua.

MacAdam Ellipses

Xa mus rau thaj tsam ntawm daim duab chromaticity uas muaj tag nrho cov xim uas tsis txawv txav, mus rau qhov nruab nrab tib neeg qhov muag, los ntawm cov xim ntawm qhov nruab nrab ntawm lub ellipse.Lub contour ntawm lub ellipse sawv cev rau qhov sib txawv ntawm chromaticity.MacAdam qhia qhov sib txawv ntawm ob lub teeb ci los ntawm ellipses, uas tau piav qhia tias muaj 'cov kauj ruam' uas qhia txog qhov sib txawv ntawm cov xim.Hauv cov ntawv thov uas pom qhov teeb pom kev zoo, qhov tshwm sim no yuav tsum raug coj mus rau hauv tus account vim tias 3-kauj ruam ellipse muaj xim qis dua li 5-kauj ruam.

CIE chromatic daim duab yog ua raws li lub cev peculiarity ntawm tib neeg lub qhov muag los soj ntsuam cov xim los ntawm kev rhuav tshem lawv mus rau hauv peb lub hauv paus chromatic Cheebtsam (peb-xim txheej txheem): liab, xiav thiab ntsuab, nyob rau sab saum toj ntawm daim duab nkhaus.CIE chromatic daim duab tuaj yeem tau los ntawm kev suav x thiab y rau txhua xim dawb.Cov xim spectrum (lossis cov xim ntshiab) tuaj yeem pom ntawm qhov nkhaus contour, thaum cov xim hauv daim duab yog xim tiag.Nws yuav tsum tau muab sau tseg tias cov xim dawb (thiab lwm yam xim nyob rau hauv nruab nrab cheeb tsam - achromatic xim los yog ntxoov grey) tsis yog xim dawb huv, thiab tsis tuaj yeem cuam tshuam rau ib lub wavelength tshwj xeeb.
