Abstract:
A dual-color projector is disclosed that includes a blue laser device configured to emit a blue laser light, a red laser device configured to emit a red laser light, and a fluorescent wheel whose surface is coated with green fluorescent powder which is excitable by the blue laser light to emit a green fluorescent light. The dual-color projector may also include a first diffusion element and a second diffusion element.

Claim (Index 15):
A dual-color projector, comprising:\n a blue laser emitter configured to emit a blue light and a red laser emitter configured to emit a red light; a fluorescent wheel comprising a first zone and a second zone, wherein the first zone is coated with green fluorescent powder, and the second zone is transmissive for the blue light; a first fixed diffuser, fixedly disposed in a blue light path of the blue light between the blue laser emitter and a light-combining element; a second fixed diffuser, which is fixedly disposed in a red light path of the red light between the red laser emitter and the light-combining element; the light-combining element configured to:\n receive the blue light output by the first fixed diffuser \n receive the red light output by the second fixed diffuser; \n output the blue light to the fluorescent wheel; and \n output the red light to a rotating diffuser in a first direction, wherein a first part of the blue light is configured to excite the green fluorescent powder to emit a green fluorescence, and a second part of the blue light is configured to pass through the second zone; \n a first reflector system configured to change direction of the second part of the blue light passed through the second zone and render the second part of the blue light passed through the second zone to incident on the light-combining element, the light-combining element is further configured to receive the second part of the blue light output by the first reflector system and the green fluorescent emitted from the fluorescent wheel, and output the second part of the blue light and the green fluorescent to the rotating diffuser in the first direction; the rotating diffuser, configured to rotate, and disposed at an upstream side of a lightpipe in a light path between the second fixed diffuser and the lightpipe, wherein the rotating diffuser comprises a green filter configured to filter the green fluorescence output by the light-combining element, a blue light diffusion zone configured to diffuse the second part of the blue light output by the light-combining element, and a red diffusion zone configured to diffuse the red light output by the light-combining element; and the lightpipe configured to receive the green fluorescence output by the rotating diffuser, the second part of the blue light output by the rotating diffuser, and the red light output by the rotating diffuser.
