An optical security element to limit counterfeiting. The element includes a lens array with a first side and a second planar side opposite the first side. A plurality of lenses are formed on the first side of the lens array, and an ink layer is provided proximate the second planar side. The ink layer provides an interlaced image, which includes a matrix of frame or image elements under each of a plurality of lens sets or virtual lenses, each of which includes at least four lenses arranged in a grouping with an equal or unequal number of lenses on a side (e.g., a 2 by 2 array or a 2 by 3 array). The interlaced element are arranged in non-sequential order in two interlacing axes (e.g., via non-sequential interlacing in both directions) to be distributed throughout an area under the at least four lenses rather than under a single lens.

An illumination lens consists of a first lens and a second lens that are arranged in this order from a light source side toward an irradiation target side. The surface of the first lens close to the light source side and the surface of the first lens close to the irradiation target side are spherical convex surfaces, and the surface of the second lens close to the light source side is a spherical convex surface. Conditional expression determined in advance about the radii of curvature of the surfaces of the first and second lenses is satisfied.

An optical device includes: a substrate including plural waveguide cores; and an optical component provided on the substrate, the optical component including plural lenses, each of the plural lenses transmitting light passing through one of the corresponding plural waveguide cores on the substrate. The substrate and the optical component are each provided with a positioning structure. The positioning structure includes plural protrusions and plural recesses provided on the substrate and the optical component. Each of the plural recesses accommodates a corresponding one of the plural protrusions, and an outer surface of each of the plural protrusions contacts a positioning surface of a corresponding one of the plural recesses. The positioning surface is a part of an inner surface of each of the plural recesses having accommodated the corresponding one of the plural protrusions to position the plural lenses relative to the substrate.

An illumination module for a vehicle includes first, second and third LEDs, and first, second and third masks aligned in with respective ones of the first, second and third LEDs. Light emitted by the first LED that passes through the first mask is a first color and light emitted by the second LED that passes through the second mask is a second color and light emitted by the third LED that passes through the third mask is a third color. When the LEDs are electrically powered to emit light, light emitted by the LEDs passes through the respective masks to project first, second and third projected images at a ground area adjacent the vehicle, each projected image having the respective color. The projected images overlap at the ground area and, combined, establish a multi-color logo or indicia at the ground area adjacent the vehicle.
