    Abstract: An optical touch system includes a non-visible light source, a screen, a first and second polarizing elements, and an optical detector. The non-visible light source emits a non-visible beam. A part of the non-visible beam passes through the screen disposed in a light path of the non-visible beam. The touch object reflects the part of the non-visible beam into an object beam when a touch object approaches or touches the screen, and the object beam passes through the screen. The first polarizing element is disposed in the light path of the non-visible beam and between the non-visible light source and the screen. The optical detector is disposed in a light path of the object beam, and senses the object beam. The second polarizing element is disposed in the light path of the object beam passing through the screen and between the screen and the optical detector.

    Abstract: A light combination device includes a reflective element and a first color separating element. The reflective element guides first color light beams emitted from at least a first light source and a second light source to propagate in a first direction. The first light source and the second light source are differently positioned in a space. The first color separating element transmits the first color light beams and reflects second color light beams emitted from at least a third light source and a fourth light source. The third light source and the fourth light source are differently positioned in the space. The first color separating element has a coating curved surface, and a curvature of the coating curved surface is varied according to positions of the third light source and the fourth light source to guide the second color light beams to propagate in the first direction.

    Abstract: The optical system of a projection display apparatus. The projection display apparatus includes a light source, a prism, a light valve, and a projection lens. A light beam emitted from the light source impinges into the prism and passes through the first surface of the prism directly to illuminate the light valve which is placed near the first surface and parallels the first surface. By the reflection of the light valve, the light beam impinges into the first surface again, and illuminates a total internal reflection surface with an incidental angle large than the critical total reflection angle, so as to reflect the light beam out of the second surface of the prism and impinge to projection lens to form an image. Therefore, the optical system can increase the transmission and decrease the number of components, and reduce its overall volume.

    Abstract: A traffic signal lamp includes a plurality of light emitting diodes and two lens sets. A first lens set has an entrance surface comprising a plurality of convex cylindrical surfaces running in a vertical direction and an exit surface comprising a plurality of slanted surface segments running in a horizontal direction. A second lens set has an entrance surface comprising a plurality of elongated concave cylindrical surfaces running in the vertical direction and an convex exit surface having a small curvature. The first lens set collimates light in the horizontal direction and limits light in a viewing angle in the vertical direction. The second lens set redistributes light uniformly in a viewing angle in the horizontal direction.
