Abstract:
A projection system has a light source, a spatial light modulator, a light recycling system, and a lens assembly. The light source emits source light toward the spatial light modulator. The spatial light modulator modulates, according to an image signal, light incident on the spatial light modulator, so as to form projection light and non-projection light. The light recycling system receives at least a portion of the non-projection light, and guides the at least a portion of the non-projection light toward the spatial light modulator. The lens assembly receives and emits the projection light to form a projection image. The projection system of the present disclosure enables efficient use of non-projection light.

Claim (Index 3):
The projection system according to  claim 1 , wherein:\n the spatial light modulator is a digital micro-mirror device; the source light is incident to the digital micro-mirror device from a light-incident side of the digital micro-mirror device; the digital micro-mirror device modulates, according to the image signal, light incident from the light-incident side of the digital micro-mirror device, wherein a micro-mirror unit of the digital micro-mirror device in an on state reflects at least a portion of the incident light to form on-state light used as the projection light, and a micro-mirror unit of the digital micro-mirror device in an off state reflects at least a portion of the incident light to form off-state light that is not used as the projection light; the light recycling system collects the off-state light that is reflected by the off-state micro-mirror unit of the digital micro-mirror device and changes an optical path of the off-state light so as to form recycled light that is projected to the digital micro-mirror device along the light-incident side of the digital micro-mirror device; and the lens assembly is located in an optical path of the on-state light that is reflected by the on-state micro-mirror unit of the digital micro-mirror device, and projects the on-state light to form the projection image.
