A light source assembly (1, 11, 13) comprising: a solid state lighting device (3); a wavelength converting element (4) arranged to receive light emitted by the solid state lighting device (3) and adapted to convert some of the received light to a different wavelength; and a scattering layer (7, 12, 14) applied to a light emitting surface (6) of the wavelength converting element (4). The scattering layer (7, 12, 14) is adapted to scatter light back to the wavelength converting element (4), and a backscattering strength of the scattering layer (7, 12, 14) varies over said light emitting surface (6) so as to reduce variations in the color of the light emitted from the light emitting surface (6). |
