Abstract
A wavelength-converting wheel has a light incident side. The wavelength-converting wheel includes a motor, a turntable, a wavelength-converting layer and a reflective element. The motor has a rotating shaft. The turntable has an inner ring portion and an annular irradiation portion. The inner ring portion is sleeved on the rotating shaft, the annular irradiation portion is connected to an outer edge of the inner ring portion, and the annular irradiation portion includes a light-reflecting region and a wavelength-converting region. The wavelength-converting layer is disposed in the wavelength-converting region and has a light receiving surface facing the light incident side. The reflective element is disposed in the light-reflecting region and has a reflective surface facing the light incident side. The light receiving surface is coplanar with the reflective surface or the light receiving surface is farther from the light incident side with respect to the reflective surface.
