Abstract: An illumination system includes a green light source, a red light source, a blue light source, a first splitter, a second splitter, and a thermoelectric cooler. The first splitter is disposed downstream of the light sources, the first splitter being capable of reflecting a first color light beam and allowing a second color light beam to pass. The second splitter is disposed at the light paths of the light sources, and the second splitter being capable of reflecting a third color light beam and allowing the first color light beam and the second color light beam to pass, wherein the color of the first color light beam, the second color light beam, and the third color light beam are substantially different. The thermoelectric cooler is thermally coupled to the red light source, and neither the green light source nor the blue light source is thermally couple to any thermoelectric cooler.

Abstract: A lamp device includes a light source, a slide and a projection lens assembly. The light source generates an illumination beam, and the slide is disposed in a light path of the illumination beam. The slide has a profile image layer and a gradient layer, and the profile image layer and the gradient layer are disposed on two opposite sides of the slide. The profile image layer converts the illumination beam into profile image light without gradients, and the gradient layer converts the illumination beam into gradient light. The projection lens assembly receives and projects the gradient light and the profile image light.

Abstract: An image displacement module is adapted for an optical apparatus to switch image positions of a plurality of plane image. The image displacement module includes a carrying base and a rotating base. The carrying base is adapted to control the rotating base to vibrate back forth within an angle, such that the imaging positions of the plane image on the horizontal direction are moved by a first distance and the imaging positions of the plane image on the vertical direction are moved by a second distance at the same time. Alternatively, the carrying base is adapted to control the rotating base to rotate relative to two axes of a reference plane, such that the plane image are moved by a distance along one of a plurality of movement directions.

Abstract: A projection film and a projection device are provided. The projection film includes a pattern layer, a first light-transmission layer, a second light-transmission layer and a plurality of light-transmission particles. The pattern layer includes a light-transmission portion and a non-light-transmission portion. The first light-transmission layer is disposed below the pattern layer. The second light-transmission layer is disposed below the first light-transmission layer. The light-transmission particles are disposed between the first light-transmission layer and the second light-transmission layer. The impurity generated by the light-transmission particles will be reduced by utilizing a second light-transmission layer having a refractive index close to the refractive index of the light-transmission particles.
