Abstract: A color wheel comprises: a rotatable disc having a light reflective face and a region of photolummescence material deposited on the light reflective face. The region of photolummescence material comprises a substantially uniform thickness layer of a mixture of particles of the photolummescence material that is deposited on the light reflective face of the disc by screen printing. The photolummescence materials can comprise blue light or UV excitable photolummescence materials such as phosphor materials or quantum dots. Color modulated light sources and a method of manufacturing a color wheel are also disclosed.
