好,现在再来说说高显色指数,CRI。我想是否可以留些家庭作业?光照领域有很多术语,那么查一下Color Rendition Index (CRI), Kelvin, lumens, lux, candlepower, foot-candles, lamberts, phot, apostilb, Photosynthetically Available Radiation (PAR), Photosynthetically Available Usable (PUR), Photosynthetic Photon Flux Density (PPFD), Einsteins, 和 E=(π/4)δ2Ω(I think the last is the name of a Fraternity)。嘿嘿!!!!!!!
