Ulwazi lwe-LED Isiqephu sesi-2 : Imiphi imibala enayo ama-LED ?

I-LED emhlophe

Ukwehluka okuningana kwenziwa phakathi nenqubo yokukhiqiza izibani ze-LED ezikhethiwe.Izindawo zechromatic ezibizwa ngokuthi 'bin' ziyimikhonto evundlile eduze komugqa we-BBL.Ukufana kombala kuncike ekwazini komkhiqizi kanye namazinga ekhwalithi.Ukukhetha okukhulu kusho izinga eliphezulu, kodwa futhi nezindleko eziphakeme.

Okumhlophe okubandayo

5000K - 7000K CRI 70

Izinga lokushisa elijwayelekile lombala: 5600K

Izinhlelo zokusebenza zangaphandle (isb, amapaki, izingadi)

Okumhlophe kwemvelo

3700K – 4300K ​​CRI 75

Izinga lokushisa elijwayelekile lombala: 4100K

Inhlanganisela nemithombo yokukhanya ekhona (isb, izikhungo zokuthenga)

Okumhlophe okufudumele

2800K – 3400K CRI 80

Izinga lokushisa elijwayelekile lombala: 3200K

Ngezinhlelo zokusebenza zasendlini, ukuthuthukisa imibala

Inhlaka

2200K

Izinga lokushisa elijwayelekile lombala: 2200K

Izinhlelo zokusebenza zangaphandle (isb, amapaki, izingadi, izikhungo zomlando)

MacAdam Ellipses

Bheka indawo ekumdwebo we-chromaticity oqukethe yonke imibala engakwazi ukuhlukaniswa, iso lomuntu elivamile, kusukela kumbala omaphakathi nendawo ye-ellipse.Ikhonta ye-ellipse imele umehluko obonakalayo we-chromaticity.I-MacAdam ibonisa umehluko phakathi kwemithombo emibili yokukhanya ngokusebenzisa ama-ellipses, achazwa 'njenganezinyathelo' ezibonisa ukuchezuka okujwayelekile kombala.Kuzinhlelo zokusebenza lapho imithombo yokukhanya ibonakala khona, lesi simo kufanele sinakwe ngoba i-ellipse enezinyathelo ezi-3 inokuhluka kombala okuphansi kunezinyathelo ezi-5.

Ama-LED anemibala

Umdwebo we-chromatic we-CIE usekelwe ekuhlukeni kokuphila kweso lomuntu ukuze kuhlolwe imibala ngokuyihlukanisa ibe izingxenye ezintathu ezibalulekile zechromatic (inqubo yemibala emithathu): obomvu, oluhlaza okwesibhakabhaka nokuluhlaza, obekwe phezulu kwejika lomdwebo.Umdwebo wechromatic we-CIE ungatholwa ngokubala u-x kanye no-y kumbala ngamunye omsulwa.Imibala ye-spectrum (noma imibala emsulwa) ingatholakala ejikeni lekhonta, kuyilapho imibala engaphakathi komdwebo iyimibala yangempela.Kumele kuqashelwe ukuthi umbala omhlophe (kanye neminye imibala endaweni emaphakathi - imibala ye-achromatic noma i-shades of grey) ayinemibala ehlanzekile, futhi ayikwazi ukuhlotshaniswa nobude obuthile be-wavelength.
