Abstract
A light source module includes a solid-state light source and a wavelength conversion wheel. The solid-state light source provides a light beam. The wavelength conversion wheel has a wavelength conversion region and a penetration region. The wavelength conversion region converts the light beam to generate a conversion beam. A substrate of the wavelength conversion wheel includes a first surface and a second surface opposite to the first surface. The wavelength conversion region includes a first conversion region and a second conversion region. The first and the second conversion regions are respectively located on the first and the second surfaces. The penetration region is connected to the first and the second surfaces. The wavelength conversion region and the penetration region are symmetrically disposed by using a symmetry point of the substrate as a reference point. A projection apparatus including the light source module is disclosed.
