1. A light source system, comprising:
a wavelength conversion layer configured to receive excitation light and generate excited light in response to the excitation light;
a transparent thermal conduction substrate configured to support the wavelength conversion layer;
an excitation light source configured to emit the excitation light from a side of the wavelength conversion layer toward the wavelength conversion layer;
a red light source configured to emit red light from a side of the transparent thermal conduction substrate toward the wavelength conversion layer;
an angle selection filter film provided between the transparent thermal conduction substrate and the wavelength conversion layer or on a surface of the transparent thermal conduction substrate opposite to the wavelength conversion layer, wherein the angle selection filter film is configured to transmit a portion of the red light which has an incident angle less than a specific angle, and reflect the excited light and a portion of the red light which has an incident angle greater than the specific angle; and,
a motor configured to rotate the transparent thermal conduction substrate and the wavelength conversion layer on the transparent thermal conduction substrate.
