Njengoba sonke sazi, ububanzi be-wavelength be-spectrum yokukhanya okubonakalayo ngu-380nm ~ 760nm, okuyimibala eyisikhombisa yokukhanya engazwakala ngeso lomuntu - obomvu, owolintshi, ophuzi, oluhlaza okotshani, oluhlaza okwesibhakabhaka nonsomi. Kodwa-ke, imibala eyisikhombisa yokukhanya yonke i-monochromatic.
Isibonelo, ubude begagasi obuphezulu bokukhanya okubomvu okukhishwa i-LED bungu-565nm. Akukho ukukhanya okumhlophe ku-spectrum yokukhanya okubonakalayo, ngoba ukukhanya okumhlophe akukhona ukukhanya kwe-monochromatic, kodwa ukukhanya okuyinhlanganisela okuhlanganiswe izibani ezihlukahlukene ze-monochromatic, njengoba nje ukukhanya kwelanga kuwukukhanya okumhlophe okuhlanganiswe izibani eziyisikhombisa ze-monochromatic, kuyilapho ukukhanya okumhlophe ku-TV enemibala. iphinde yakhiwe ngemibala emithathu eyinhloko obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka.
Kuyabonakala ukuthi ukwenza i-LED ikhiphe ukukhanya okumhlophe, izici zayo ze-spectral kufanele zimboze lonke uhla lwe-spectral olubonakalayo. Kodwa-ke, akunakwenzeka ukwenza i-LED enjalo ngaphansi kwezimo zobuchwepheshe. Ngokocwaningo lwabantu ngokukhanya okubonakalayo, ukukhanya okumhlophe okubonakala emehlweni omuntu kudinga okungenani ingxube yezinhlobo ezimbili zokukhanya, okungukuthi, ukukhanya kwamaza amaza amabili (ukukhanya okuluhlaza okwesibhakabhaka+ nokukhanya okuphuzi) noma ukukhanya kwamaza amathathu (ukukhanya okuluhlaza okwesibhakabhaka+ukukhanya okuluhlaza+ okubomvu). ukukhanya). Ukukhanya okumhlophe kwalezi zindlela ezimbili ezingenhla kudinga ukukhanya okuluhlaza okwesibhakabhaka, ngakho ukuthatha ukukhanya okuluhlaza okwesibhakabhaka sekuphenduke ubuchwepheshe obuyinhloko bokukhiqiza ukukhanya okumhlophe, okungukuthi, "ubuchwepheshe bokukhanya okuluhlaza okwesibhakabhaka" obulandelwa izinkampani ezinkulu zokukhiqiza ze-LED. Kukhona abakhiqizi abambalwa kuphela abafunde "ubuchwepheshe bokukhanya okuluhlaza okwesibhakabhaka" emhlabeni, ngakho-ke ukukhuthazwa kanye nokusetshenziswa kwe-LED emhlophe, ikakhulukazi ukukhuthazwa kokukhanya okuphezulu kwe-LED emhlophe e-China kusenenqubo.
