Abstract
A projection system including a lighting system, a screen, a color filter separating light emitted from the lighting system according to wavelengths of the light, a first reflecting mirror reflecting the light passing through the color filter to change a path of the light, a display device provided in a predetermined position in the first reflecting mirror, a second reflecting mirror reflecting light reflected from the first reflecting mirror toward the display device, and a projection lens unit enlarging and projecting a color image formed by the display device onto the screen.
Claims21
A projection system comprising:
- a lighting system;
- a screen;
- a color filter separating light emitted from the lighting system according to wavelengths of the light;
- a first reflecting mirror reflecting the light passing through the color filter to change a path of the light;
- a display device provided in a predetermined position in the first reflecting mirror;
- a second reflecting mirror reflecting light reflected from the first reflecting mirror toward the display device;
- and
- a projection lens unit enlarging and projecting a color image formed by the display device onto the screen.
A lighting system comprising:
- a lamp light source radiating light;
- a reflector reflecting the light emitted from the lamp light source to emit the light in one direction;
- and
- an intercepting unit reflecting a portion of the light emitted from the lamp light source toward the reflector so that the light emitted from the reflector has an annular light distribution.
A projection system comprising:
- a first reflecting mirror;
- a second reflecting mirror;
- and
- a display device provided in the surface of the first reflecting mirror;
- wherein the second reflecting mirror receives light reflected from the first reflecting mirror and reflects the received light toward the display device.
