Abstract

A phosphor wheel and a projection apparatus with the phosphor wheel are disclosed. A phosphor wheel includes a driving motor, a temperature interference element, a substrate and at least one light wavelength converting layer. The driving motor includes a motor body and a rotating member. The motor body drives the rotating member to rotate relative to the motor body along a rotation axis. The temperature interference element is connected with the rotating member and the substrate. The motor body drives the rotating member to rotate the temperature interference element and the substrate relative to the motor body. The substrate includes a first surface and a second surface disposed opposite to each other. The second surface is located between the first surface and the rotating member. The light wavelength converting layer is disposed on the first surface of the substrate.
