Abstract
A wavelength conversion module is configured to receive an excitation beam. The wavelength conversion module includes a substrate and a wavelength conversion material arranged on the substrate. The substrate includes a ring-shaped light irradiation region, and the wavelength conversion material is annularly arranged on at least part of the ring-shaped light irradiation region. A first color light obtained through conversion when the excitation beam is incident to the wavelength conversion material of the ring-shaped light irradiation region in a first time sequence has a first light intensity, the first color light obtained through conversion when the excitation beam is incident to the wavelength conversion material of the ring-shaped light irradiation region in a second time sequence has a second light intensity, and the first light intensity and the second light intensity are different. In addition, a projection device is also provided.
