Na The LED Emitting White Light

Joalokaha bohle re tseba, bolelele ba maqhubu a khanya e bonahalang ea khanya ke 380nm ~ 760nm, e leng mebala e supileng ea khanya e ka utluoang ke leihlo la motho - e khubelu, ea lamunu, e mosehla, e tala, e tala, e putsoa le e pherese. Leha ho le joalo, mebala e supileng ea khanya kaofela ke monochromatic.

Mohlala, tlhōrō ea bolelele ba lebone le lefubelu le hlahisoang ke LED ke 565nm. Ha ho na leseli le lesoeu maboneng a khanya e bonahalang, hobane leseli le lesoeu ha se leseli le monochromatic, empa ke leseli le kopaneng le entsoeng ka mefuta e fapaneng ea mabone a monochromatic, joalo ka ha khanya ea letsatsi e le leseli le lesoeu le entsoeng ka mabone a monochromatic a supileng, athe leseli le lesoeu ka mebala ea TV. e boetse e entsoe ka mebala e meraro ea mantlha e khubelu, e tala le e putsoa.

Hoa hlokomeleha hore ho etsa hore LED e hlahise leseli le lesoeu, litšoaneleho tsa eona tsa spectral li lokela ho koahela mefuta eohle e bonahalang ea spectral. Leha ho le joalo, ho ke ke ha khoneha ho etsa LED e joalo tlas'a maemo a theknoloji. Ho latela lipatlisiso tsa batho mabapi le leseli le bonahalang, leseli le lesoeu le bonoang mahlong a motho le hloka bonyane motsoako oa mefuta e 'meli ea leseli, e leng, leseli la maqhubu a mabeli (leseli le leputsoa+leseli le mosehla) kapa lebone la maqhubu a mararo (leseli le leputsoa+lebone le letala+lefubelu). kganya). Leseli le lesoeu la mekhoa e 'meli e ka holimo le hloka leseli le leputsoa, ​​kahoo ho nka leseli le leputsoa ho fetohile theknoloji ea bohlokoa bakeng sa ho etsa leseli le lesoeu, ke hore, "theknoloji ea leseli le leputsoa" e lateloang ke lik'hamphani tse kholo tsa tlhahiso ea LED. Ho na le bahlahisi ba 'maloa feela ba tsebang "theknoloji ea leseli le leputsoa" lefatšeng, kahoo ho khothaletsoa le ho sebelisoa ha LED e tšoeu, haholo-holo ho phahamisa khanya e phahameng ea LED e tšoeu Chaena ho ntse ho e-na le ts'ebetso.
