Abstract: A projector is provided, which includes a red substrate, a green substrate, a blue substrate, an X-cube, an electronic control element, a light guide element, a light valve element, and a projection lens. The red substrate, the green substrate, and the blue substrate respectively illuminate three surfaces of the X-cube, and the light is mixed in the X-cube and then exits from a light emitting surface. The electronic control element controls the red substrate, the green substrate, and the blue substrate. The light guide element is used for reflecting the light from the light emitting surface of the X-cube. The light valve element is used for reflecting the light from the light guide element back to the light guide element, and the light passes through the light guide element and then projected by the projection lens onto a projection plane area. Thereby, the ON/OFF switch time of the present invention is shortened, the temperature may not get over high, the optical efficiency is enhanced, and the whole volume is significantly reduced.

Abstract: The invention relates to a zoom lens for DLP projector. The zoom lens of the invention comprises a focus group, a zoom group and a compensation group. The zoom group comprises three zoom units with positive, negative, positive optical power respectively. The compensation group comprises a first compensation unit, a second compensation unit, an aperture stop and a third compensation unit. Corresponding to the aperture stop, the compensation lens of the compensation units have positive radius, positive radius, positive radius and negative radius respectively. The zoom lens of the invention utilizes the zoom group and the compensation group so that firstly, the F-number of the zoom lens of the invention can be fixed at 2.2; secondly, the relative luminance of the zoom lens of the invention can be up to 60% even at extreme corner; thirdly, the tolerance of the zoom lens of the invention is comparatively excellent.

Abstract: An automotive headlight system and an adaptive automotive headlight system with instant compensation control are provided. The automotive headlight system includes a light source, a total internal reflection prism, a digital reflecting element, a freeform lens, and a multi-curve-reflector. The total internal reflection prism is used for redirecting and reflecting light beams from the light source. The digital reflecting element is controlled to switch to a plurality of states with regard to reflected light beams from the total internal reflection prism then compensation patterns will be promptly given during different states. The freeform lens is used for controlling directions of the light beams from the digital reflecting element. The multi-curve-reflector has a plurality of radii of curvature for reflecting the light beams from the freeform lens. As the automotive headlight system merely uses optical refractive and reflecting elements so that the number of components and cost is greatly reduced as compared with the prior art. Furthermore, the most important is that this invention proposes a new design and instant and personalized compensation solution to reduce more driver's risks.

The lens with a negative dioptre closer to the lens with a positive dioptre is cemented to the positive-dioptre lens. The fourth lens set contains a lens with a negative dioptre and two non-spherical surfaces. The wide-angle zoom lens moves the second and the fourth lens set along its optical axis to adjust its zoom and moves the fourth lens set to focus.
