  • Patent number: 8846172
    Abstract: Disclosed herein are a laminated composite and process for making the same. The laminated composite includes at least one wavelength-converting layer and at least one non-emissive layer, wherein a vertical relief gap pattern defines the composite into a plurality of discrete separable portions, and the discrete separable portions are breakably joined by a non-emissive layer. Separation along the relief gap pattern reduces color variation amongst the discrete portions and processes.
