Abstract: A projection lens includes a first lens, a second lens, an aperture stop, a third lens, a fourth lens, a fifth lens, a sixth, and a concave mirror sequentially arranged from a minified side to a magnified side. An outer diameter of the second lens is less than an outer diameter of the first lens. An outer diameter of the fifth lens is greater than that of the fourth lens. An outer diameter of the sixth lens is less than that of the fifth lens. The first lens, the second lens, the aperture stop, and the third lens are fixed relative to the concave mirror and the fourth lens is capable of moving along an optical axis relative to the concave mirror when the projection lens is in focusing. The projection lens includes 9 to 30 lenses with refractive power. A projector using said projection lens is also provided.

Abstract: A three-dimensional printing apparatus includes a container and a projecting structure. The container is configured to contain a liquid photosensitive material. The projecting structure is configured to provide a variety of molding beams to irradiate the liquid photosensitive material. The photoinitiator is suitable for polymerizing with a monomer after receiving the first molding beam with the first wavelength to form a solidified layer with a first color, and the photoinitiator is suitable for polymerizing with the monomer after receiving the second molding beam with the second wavelength to form a solidified layer with a second color, wherein the first color is different from the second color. The projecting structure comprises a light combiner module, disposed on the transmission paths of a variety of light beams. The wavelengths of the first molding beam and the second molding beam are between 355 nm to 415 nm.

Abstract: A vehicle lighting system includes a light processing unit, a non-uniform projection unit, a sensing unit, a judgment unit, and an operation unit. The light processing unit is capable of changing an intensity profile of a light beam, and the judgment unit receives an image signal from the sensing unit to determine whether to change the intensity profile of the light beam according to the image signal. When the intensity profile needs to be changed in accordance with the judgment result, the operation unit calculates out a desired intensity profile and outputs a control signal containing information about the desired intensity profile to the light processing unit, and the light processing unit changes the intensity profile of the light beam according to the control signal and sends out the light beam with the desired intensity profile.
