Patent ID: 10824068

Abstract:
The invention discloses a phosphor wheel, and a projector using the phosphor wheel. The projector includes an illumination system, a light valve, and a projection lens. The illumination system is used to provide an illumination beam. The light valve is disposed on a transmission path of the illumination beam and converts the illumination beam into an image beam. The projection lens is disposed on a transmission path of the image beam. The illumination system includes an excitation light source and a phosphor wheel. The excitation light source is used to provide an excitation beam to the phosphor wheel. The phosphor wheel includes a motor, a disk plate, a reflection member, and at least one phosphor layer. The motor has a shaft. The disk plate is connected to the shaft. In the invention, the phosphor wheel has better reliability and rigidity, and has the effect of enhancing heat dissipation.
