Ua tiav tag nrho - spectrum cog teeb pom kev los ntawmkev hloov pauv phosphortso siab rau kev hloov pauv cov pa tawm ntawm thawj LED- feem ntau yog xiav lossis ze ntawm -UV nti- mus rau qhov dav dav siv cov khoom siv phosphor. Thaum lub siab-zog photons los ntawm LED tawm tsam cov phosphor txheej, ib feem ntawm lub zog ntawd tau nqus thiab rov ua dua - tawm ntawm cov wavelengths ntev dua, ua rau cov spectrum tsis tu ncua uas tuaj yeem ua raws li lub hnub ci ntuj.
Txoj hauv kev no yog siv dav hauv cov LEDs dawb, qhov chaw xiav nti ua ke nrog cov xim daj lossis ntau yam -cov khoom siv phosphors tsim cov teeb pom kev sib npaug thoob plaws qhov pom. Nyob rau hauv horticulture, advanced phosphor blends yog engineered los txhim kho tej cheeb tsam, xws li liab (nyob ib ncig ntawm 600-700 nm) rau photosynthesis thiab ntsuab (500-600 nm) rau tob canopy nkag. Qee lub tshuab kuj suav nrog deb- cov zis liab los ntawm cov phosphor tshwj xeeb los cuam tshuam cov lus teb paj.
Ib qho txiaj ntsig tseem ceeb ntawm kev hloov pauv phosphor yog nws qhov yooj yim. Muab piv rau ntau-chip sib xyaw, nws yuav tsum muaj tsawg dua LED channels thiab kev tswj tus tsav tsheb tsawg dua, ua rau tus nqi qis dua thiab txhim kho kev ntseeg tau. Nws kuj ua kom zoo spectral uniformity, raws li lub teeb emitted yog ib txwm sib xyaw ntawm qhov chaw, tshem tawm cov teeb meem xim sib cais.
Txawm li cas los xij, phosphor hloov dua siab tshiab muaj qhov yooj yim dua nyob rau hauv spectral tuning thiab tej zaum yuav raug kev txom nyem los ntawm kev hloov pauv, qhov twg qee lub zog yog dissipated li cua sov. Txawm li cas los xij, nws tseem yog qhov ua tau zoo thiab siv tau zoo rau kev xa cov teeb pom kev zoo, tag nrho - spectrum cog teeb pom kev zoo.
