Classification: CPC H  C | IPC C  H

Claim 13:
14. The method of claim 13 wherein the wavelength converting particles and the binder are characterized by a first color point, the method further comprising:
forming a layer that includes second wavelength converting particles and a second binder, wherein the second wavelength converting particles and the second binder are characterized by a second color point that differs from the first color point; and
heat or pressure laminating the layer of the second wavelength converting particles and the second binder onto the porous support structure of the wavelength converting layer, so that (i) the wavelength converting layer exhibits a predetermined color point, (ii) all or at least a portion of the thickness of the porous support structure lacks any of the second wavelength converting particles, and (iii) all or at least a portion of the thickness of the layer of the second wavelength converting particles and the second binder lacks any fibers or strings of the one or more mesh layers.
