摘要：

The invention provides a method of selecting the suitability of a lighting device (100) for use in cheese lighting, the method comprising (a) defining a normalization factor (k) for a spectral power distribution (SPD(λ)) of lighting device light (101) of said lighting device (100) in a wavelength range of 380-780 nm, (b) defining the lighting device (100) suitable for use in cheese lighting when a cheese damage function value (CDFV) is equal to or below 2, wherein the cheese damage function value (CDFV) is defined as: (I) wherein: (II) wherein y (λ) is a 2-degree color matching function, and wherein DF(λ)=1 for 380 nm≤；λ<；410, and wherein for 410≤；λ≤；780: (III).$\begin{array}{cc}\mathrm{CDFV}=k\times \underset{\lambda }{\overset{}{\sum ；}}\mathrm{SPD}\left(\lambda \right)·\mathrm{DF}\left(\lambda \right)·\mathrm{\Delta ；\lambda }& \left(I\right)\\ k=\frac{100}{\underset{\lambda }{\overset{}{\sum ；}}\mathrm{SPD}\left(\lambda \right)·\stackrel{\_}{y}\left(\lambda \right)·\mathrm{\Delta ；\lambda }}& \left(\mathrm{II}\right)\\ \mathrm{DF}\left(\lambda \right)=0.95\times e^{-{\left(\frac{\lambda -410}{22}\right)}^2}\end{array}$
