摘要： An illumination system adapted to a projection apparatus is provided, including a light source module, a light color modulating module, and a control unit. The light color modulating module has a plurality of light color modulating units and is disposed in a transmission path of a light beam. The light color modulating module is capable of moving so that the light color modulating units move into the illumination region of the light beam. When the control unit determines that a boundary of any two adjacent light color modulating units has moved into the illumination region of the light beam, the control unit switches the light source module to an off-state. When the boundary of any two adjacent light color modulating units has moved away from the illumination region of the light beam, the control unit switches the light source module to an on-state. An illumination control method is also provided.

摘要： An image projecting apparatus includes a light source, a relay lens, a reflective light valve, and a projection lens. The light source is capable of emitting a light beam. The relay lens is disposed to permit the light beam provided by the light source to pass therethrough, and has a lens periphery formed with a notch. The reflective light valve is spaced apart from the relay lens, and is disposed to receive and modulate the light beam passing through the relay lens into an image light beam. The projection lens is disposed proximate to the notch of the relay lens, and is capable of projecting the image light from the reflective light valve to display an image onto a screen. The relay lens has a plurality of light-absorbing regions proximate to the notch for reducing a light-splitting effect attributed to the notch.

摘要： A projector comprising a light engine, a detector, and a control unit is disclosed. The light engine comprises a light source and generates a projection beam based on the light from the light source. The space which the projection beam passes through is defined as a projection area, and a security area is defined by the projector to include or overlap the projection area. The detector detects whether a living organism is in the security area or not. When the detector detects a living organism in the security area, the detector generates a warning signal and transmits the warning signal to the control unit. After receiving the warning signal, the control unit directs the projector to enter a security mode to protect the living organism from being hurt.
