Abstract
A laser light source is disclosed that includes a laser device, a first diffusion element, a fluorescence wheel, and a second diffusion element. The fluorescence wheel emits a fluorescent light when excited by the laser light, and before reaching the fluorescence wheel, the laser light emitted by the laser device is transmitted through the first diffusion element that is fixedly arranged. As the second diffusion plate rotates about its axis, the laser light from the first diffusion element and the fluorescent light from the fluorescence wheel transmit through the second diffusion plate.
