  • Patent number: 11422448
    Abstract: A white light source comprises a luminescent layer comprising a phosphor and light scattering material disposed in a binder, and a light source arranged to illuminate the luminescent layer with blue light. The white light source outputs white light comprising converted phosphor emission light from the phosphor illuminated by the blue light and unconverted scattered blue light that is scattered by the light scattering material. The unconverted scattered blue light has a spatial distribution matching a spatial distribution of the converted phosphor emission light. In some embodiments the spatial distributions are approximately Lambertian spatial distributions. The white light source may comprise a phosphor wheel including a disk-shaped substrate on which the luminescent layer is disposed as a phosphor ring. The phosphor ring may comprise the phosphor and light scattering material disposed in the binder with uniform composition around the annulus of the phosphor ring.
