Abstract: Provided is a high-decorativeness illumination device that utilizes lenticular lens sheets. An illumination device includes first to third lenticular lens sheets, an LED light source, and a casing. The first and second lenticular lens sheets are laminated such that an angle formed by plano-convex cylindrical lenses falls within a first angle range which is greater than 0 degrees and is less than 30 degrees. Accordingly, moire fringes appear in illumination light rays. The third lenticular lens sheet is laminated on the first and second lenticular lens sheets such that angles formed by plano-convex cylindrical lenses fall within a second angle range which is equal to or greater than 30 degrees and is equal to or less than 90 degrees.

Abstract: Provided is a high decorative illumination device that utilizes a lenticular lens sheet. An illumination device includes a lenticular lens sheet and an LED light source. The lenticular lens sheet is curved in an X direction, and a convex surface is formed in a concave shape. The LED light source is positioned inside the convex surface of the lenticular lens sheet. First and second reflection components from first and second bright points which are acquired by reflecting irradiation light rays from the LED light source from plano-convex cylindrical lenses are incident on left and right eyes of an observer who observes the illumination device. The observer observes a virtual image as if a light emitter is present in a position in which the first and second reflection components cross each other.

Abstract: A decorative member as a three-dimensional molded article is formed in a curved sheet shape. In the decorative member, a plurality of cylindrical lenses is arrayed in parallel on one surface. In cylindrical lenses in a molding portion and cylindrical lenses in a molding portion, the orientations of the lenses are different from each other. In addition, in the cylindrical lenses in the molding portion and the cylindrical lenses in the molding portion, the shapes of cross sections of these cylindrical lenses in the array direction are different from each other.

Abstract: A decorative cover includes a lenticular lens sheet, an outer frame, a connection point, and a plurality of LED chips. The outer frame is fitted onto an outer periphery of a smartphone. The lenticular lens sheet is integrated with the outer frame and covers a rear surface of the smartphone. The plurality of LED chips is arranged parallel to a longitudinal direction of cylindrical lenses on a flat surface side of the lenticular lens sheet. A drive unit changes a light emission state of each of the plurality of LED chips. The drive unit is connected with a control unit of the smartphone through a connection point and the connection point. The drive unit changes the light emission state of each LED chip in accordance with an operating state of the smartphone operated by the control unit.

Abstract: Provided is a decorative sheet capable of obtaining an equivalent or higher quality texture than that of a real carbon fiber sheet. The decorative sheet (10) includes a lenticular lens sheet (11) and an image forming layer (13). The lenticular lens sheet includes a plurality of cylindrical lenses (15). The image forming layer includes a first sub-divided region (Si), a second sub-divided region (S2), and an intermediate region (SM) in a unit region corresponding to each of the cylindrical lenses. By changing an observation direction of the decorative sheet, a first-design (P1), a gradation-design (PG), and a second-design (P2) are sequentially observed. The first-design and the second-design have mutually inverted densities. Images of the first-design, the second-design, and the gradation-design are formed in the first sub-divided region, the second sub-divided region, and the intermediate region, respectively, in a state where they are sub-divided in a belt shape.
