Technology yog tib neeg-taw qhia, thiab "tag nrho spectrum" lub tswv yim uas tau ua nrov hauv kev lag luam teeb pom kev zoo nyob rau xyoo tas los no tuaj yeem hais tias yog cov khoom lag luam zoo tshaj plaws uas ua rau lub tswv yim no. Muaj coob tus neeg txawm npe nws thaum kho kom zoo nkauj thiab xav kom nruab tag nrho-spectrum teeb. Yog li cas peb yuav tsum to taub lub tswvyim ntawm tag nrho cov spectrum? Yuav ua li cas txog lub tswvyim?
1) Ua ntej, cia peb tham txog lub spectrum. Txhua tus neeg uas tau ua si nrog lub prism paub tias lub teeb tuaj yeem decomposed mus rau hauv ib lub teeb ntawm monochromatic vim dispersion. Lub spectrum yog ib pawg ntawm lub teeb uas tau muab faib ua ib lub teeb ntawm monochromatic tom qab tau muab faib los ntawm ib qho kev faib tawm (xws li prism thiab grating), thiab tom qab ntawd teem caij raws li lub wavelength.
2) Txawm li cas los xij, cov teeb sib txawv muaj qhov sib txawv ntawm lub zog sib txawv hauv cov spectrum, thiab qhov sib piv ntawm cov khoom sib txawv ntawm ntau lub wavelengths yuav txawv. Lub hnub ci muaj qhov dav dav tsis tu ncua, thiab 99.9% ntawm lub zog yog concentrated nyob rau hauv infrared, pom thiab ultraviolet cheeb tsam.
Lub "tag nrho spectrum" nyob rau hauv lub teeb pom kev zoo yog hais txog lub teeb emitted los ntawm lub fixture. Nws spectrum yog ze rau lub hnub ci spectrum. Tshwj xeeb tshaj yog nyob rau hauv qhov pom, qhov kev faib ua feem ntawm ntau yam wavelength Cheebtsam zoo ib yam li lub hnub ci. Cov xim rendering Performance index ntawm lub teeb yog ze rau lub hnub ci. Xim rendering index.
3) Kev hais lus nruj me ntsis, cov roj teeb incandescent kuj suav tias yog tag nrho cov spectrum. Vim hais tias cov spectrum ntawm incandescent teeb yog tas mus li thiab npog thaj tsam lub teeb pom kev, incandescent teeb muaj ib tug siab xim rendering Performance index thiab muaj peev xwm cuam tshuam qhov tseeb xim ntawm cov khoom yog illuminated. Txawm li cas los xij, vim muaj ob qhov tsis txaus ntseeg ntawm cov teeb ci incandescent: lub teeb pom kev zoo thiab lub neej luv luv, cov teeb ci incandescent yog "kim". Txawm tias cov teeb ci incandescent nrog lub teeb xim zoo tau raug hloov los ntawm lub cim tshiab ntawm lub teeb ntsuab.
4) Nyob rau hauv xyoo tas los no, kev txhim kho ntawm LED tau ua tiav, rhuav tshem cov teeb meem ntawm cov thev naus laus zis tseem ceeb. Cov neeg tau hloov kho cov txheej txheem LED ib txwm siv ntawm kev siv xiav LED kom zoo siab phosphors siv cov ntshav LED kom zoo siab phosphor kom tau txais cov xim liab, ntsuab thiab xiav xim. Tom qab cov teeb xim sib xyaw thiab superimposed, lawv tsim Lub Teeb nrog ib qho zoo sib xws rau hnub ci. Cov thev naus laus zis no sib xyaw cov yam ntxwv thiab cov khoom lag luam zoo ntawm LED nws tus kheej los ua kom tag nrho-spectrum LEDs ntau dua nyob rau hauv txoj kab nrog cov kev xav tau thiab cov qauv ntawm lub lag luam teeb pom kev zoo, yog li tag nrho-spectrum LEDs kuj nrov heev.
