Gauss simulation is an effective tool for designing light-emitting-diode (LED) light sources. This paper proposes a new two-part Gauss simulation model to simulate a YAG:Ce phosphor-coated LED (PC-LED). This model divides the emission spectra of YAG:Ce phosphor into two parts. and they use different half spectral widths in the Gauss function to accurately simulate the spectra of YAG:C... https://cosmeticssquadets.shop/product-category/liquid-soap/
