    Abstract: A lens includes an optical portion configured to refract light, and a flange portion extending from the optical portion, wherein a first region having first surface roughness, a second region having second surface roughness, and a third region having third surface roughness are sequentially disposed from the optical portion toward the flange portion, on at least one of an object-side surface and an image-side surface of the flange portion, the first surface roughness and the third surface roughness are greater than the second surface roughness, and a light blocking portion is disposed in the second region.

    Abstract: An optically diffusive film includes a structured first major surface with a plurality of substantially parallel, substantially planar first surfaces arranged across the first major surface at a plurality of different first height levels. A height difference between any two of the first surfaces is S times Hmin, where S is a number within 15% of an integer and Hmin is a height difference between lowest and next-lowest first surfaces. For a substantially collimated incident light and for a first wavelength in a human-visible wavelength range, the optically diffusive film has an optical haze, Hv, and an optical clarity, Cv, and for a second wavelength in an infrared wavelength range, the optically diffusive film has an optical haze, Hi, and an optical clarity, Ci, such that the ratio Hv/Hi is greater than or equal to 1.5 and the ratio Ci/Cv is greater than or equal to 1.5.

    Abstract: The present disclosure describes lighting assemblies (e.g., taillight assemblies) for vehicles that diffuse and block light transmission from a centralized light source, which inhibits (if not entirely prevents) the creation and perception of hotspots from one or more points-of-view (e.g., from the sides and/or the rear of the vehicle) while producing a more homogenous overall appearance. In one embodiment of the disclosure, the lighting assembly includes: a light source; a diffuser that is spaced axially from the light source; a lens that is spaced axially from the diffuser; and a shield that is located axially between the diffuser and the lens. The diffuser includes first and second lateral ends and is configured to receive and disperse light from the light source through the lighting assembly. The shield is configured to interfere with light transmission from the light source through the at least one lens and thereby inhibit hotspot perception.

    Abstract: A pseudo random dot pattern is easily created by a geometric approach. A pseudo random dot pattern 1A is created by arranging zigzag arrangements R at a predetermined pitch in an x direction on an xy plane while periodically altering positions thereof in a y direction, the zigzag arrangements R each including an arrangement Rb and an arrangement Rc repeatedly provided at predetermined intervals in the y direction, the arrangement Rb including dots arranged at a positive inclination, the arrangement Rc including dots arranged at a negative inclination.
