Abstract
Provided is a light source device, including: a first light source module, a set of lenses, a first light-homogenization component, a first light-combination device, and a wavelength conversion device. The first light source module is configured to emit a first light beam having first wavelength. The set of lenses and the first light-homogenization component are located in propagation path of the first light beam. The set of lenses is configured to converge the first light beam. The first light-homogenization component is configured to homogenize the first light beam. A second light beam formed by homogenization is incident on the first light-combination device, and the first light-combination device is located at a focus position of the set of lenses. The wavelength conversion device is located in propagation path of a third light beam emitted from the first light-combination device and configured to form excited light having second wavelength under excitation.
