Ulwazi lwe-LED Isiqendu 2 : Yeyiphi imibala enayo ii-LED ?

I-LED emhlophe

Ukwahlula okuninzi kwenziwa ngexesha lenkqubo yokuvelisa izibane ze-LED ezikhethiweyo.Imimandla yekhromatiki ebizwa ngokuba 'ngumgqomo' ziikhonto ezithe tye ecaleni komgca we-BBL.Ukufana kombala kuxhomekeke kulwazi lomenzi kunye nemigangatho yomgangatho.Ukukhetha okukhulu kuthetha umgangatho ophezulu, kodwa kunye neendleko eziphezulu.

Emhlophe ebandayo

5000K – 7000K CRI 70

Ubushushu bombala oqhelekileyo: 5600K

Usetyenziso lwangaphandle (umz., iipaki, iigadi)

Umhlophe wendalo

3700K – 4300K ​​CRI 75

Ubushushu bombala oqhelekileyo: 4100K

Udibaniso nemithombo yokukhanya esele ikhona (umzekelo, amaziko okuthenga)

Emhlophe eshushu

2800K – 3400K CRI 80

Ubushushu bombala oqhelekileyo: 3200K

Ukusetyenziswa kwangaphakathi, ukunyusa imibala

I-Amber

2200K

Ubushushu bombala oqhelekileyo: 2200K

Usetyenziso lwangaphandle (umz., iipaki, iigadi, amaziko embali)

MacAdam Ellipses

Jonga indawo ekwidayagram yechromaticity equlethe yonke imibala engacaciswanga, kwi-avareji yeliso lomntu, ukusuka kumbala osembindini we-ellipse.Icontour yeellipse imele umahluko obonakalayo wechromaticity.I-MacAdam ibonisa umahluko phakathi kwemithombo yokukhanya emibini ngokusebenzisa ii-ellipses, ezichazwa 'njengezinyuko' ezibonisa ukutenxa komgangatho wombala.Kwizicelo apho imithombo yokukhanya ibonakala khona, le nto kufuneka ithathelwe ingqalelo kuba i-ellipse ye-3-step inombala ophantsi ongaphantsi kune-5-step.

Ii-LED ezinemibala

Umzobo wechromatic weCIE usekwe kwindalo engaqhelekanga yeliso lomntu ukuvavanya imibala ngokuyiqhekeza ibe ngamacandelo amathathu asisiseko ekhromatic (inkqubo yemibala emithathu): obomvu, oluhlaza okwesibhakabhaka, oluhlaza, obekwe phezulu kumzobo wegophe.Umzobo wechromatic weCIE unokufunyanwa ngokubala ux kunye noy kumbala osulungekileyo ngamnye.Imibala ye-spectrum (okanye imibala ecocekileyo) inokufumaneka kwi-contour curve, ngelixa imibala engaphakathi kwidayagram iyimibala yokwenene.Kufuneka kuqatshelwe ukuba umbala omhlophe (kunye neminye imibala kwindawo ephakathi - imibala ye-achromatic okanye i-shades of grey) ayikho imibala ecocekileyo, kwaye ayikwazi ukudibaniswa nobude obuthile.
