This invention discloses a color enhancement method for a single phosphor wheel architecture, comprising a projector using a single phosphor wheel. This projector does not have a color wheel; yellow (Y), red (R), and green (G) are all generated from the phosphor wheel and produced by laser irradiation of phosphors. Blue (B) is generated from the optical path behind the phosphor wheel by creating a hole in the phosphor wheel. The laser irradiation occurs in the optical path system where a blue laser excites the phosphor. The red (R) phosphor produced after irradiation has a poor effect, with a color bias towards orange. Without changing the single phosphor wheel architecture, the color coordinates of red (R) are improved by adding a glass filter to the surface of the red (R) phosphor. To improve the color of a single phosphor wheel, this invention requires adding a filter to the area where color improvement is needed. However, the added filter's refractive index and thickness cause the original focal point to shift backward. This is compensated for by locally processing an aluminum sheet to correct the shift in focal point, allowing each color to achieve its optimal color coordinates and efficiency.
