An optical component for an LED lighting arrangement comprises a transparent material having a surface and one or more photoluminescent (phosphor) materials deposited as a layer on the surface of the transparent material. The phosphor material layer can be deposited using a deposition approach including spraying, dropping, printing, painting, spin coating or tape casting. The phosphor material layer has a thickness in a range of 20 to 500 μm. The component can further comprising a light diffusing material which can be provided in a separate layer from the phosphor material layer or provided in the phosphor material layer. The light diffusing material can be deposited using a deposition approach including spraying, dropping, printing, painting, spin coating or tape casting. |
