Abstract:
A laser light source for projector includes a laser light source module, first and second light receiving modules, a phosphor wheel, and a light combining module. The phosphor wheel has a first and a second side. The phosphor wheel receives the laser and converts the laser into first and second fluorescent light. The phosphor wheel receives the laser at a first side and emits the first fluorescent light. The phosphor wheel emits the second fluorescent light at a second side. After the first fluorescent light and the second fluorescent light passes through the first and second light receiving modules, at least one of the directions of optical axes of the first and second fluorescent light is changed. The light combining module receives the first and second fluorescent lights and emits a combined light.
