VISIBLE AND INFRARED LIGHT SOURCE FOR ILLUMINATION SYSTEM AND PROJECTION DEVICE COMPRISING THE SAME

摘要

An illumination system and a projection device comprising the same are provided. The projection device comprises an image-forming system and the illumination system. The illumination system comprises a first light source device, a second light source device and a first light guiding device. The first light source device generates a visible light, while the second light source device directly generates a substantially pure infrared light. The light guiding device is adapted to guide the visible light and the infrared light to the image-forming system for processing to make the visible light form a visible light image and make the infrared light form an infrared light image.

1. An illumination system for a projection device, the illumination system comprising:
a first light source device configured to generate:
a red light to be outputted to a first light processing element to form a red light image;a green light to be outputted to a second light processing element to form a green light image; anda blue light to be outputted to a third light processing element to form a blue light image;a first light guiding device configured to combine said red, green, and blue light images into a visible light image;a second light source device directly generating a substantially pure infrared light and outputting said infrared light to a fourth light processing element to form an infrared light image; anda second light guiding device guiding the visible light image and the infrared light image to project outward of an image-forming system of said projection device.
