Abstract:
A color wheel includes a phosphor wheel, a color correction wheel, a rotation shaft, and a metal piece fixed on the rotation shaft, and the phosphor wheel and the color correction wheel are fixed together with the metal piece, such that they both contact the metal piece and heat generated by the phosphor wheel can be quickly transmitted to the metal piece and the color correction wheel and emitted into the air to cool the phosphor wheel.
