Abstract
Provided is a lighting device capable of manipulating a wider range of parameters to reproduce various light sources. A light source unit 10 includes, for example, a liquid crystal panel and a backlight, and each pixel is a light source capable of adjusting innumerable hues and intensities capable of adjusting hue and intensity. A lenticular lens 20 includes an array of a plurality of lenticules, and is arranged such that a plurality of light sources capable of adjusting hue and intensity is associated with each lenticule. In addition, on the outer periphery of the cylindrical portion of each lenticule, a partition is formed to block emission light from the pixel below the adjacent lenticule, thereby preventing repetition.
Claims12
A lighting device, comprising:
- a light source unit that includes a plurality of light sources in a two-dimensional array;
- and
- a light ray control unit configured to control a respective radiation direction of each light source of the plurality of light sources, wherein
- the light ray control unit includes a lenticular lens,
- the lenticular lens includes a plurality of lenticules,
- each lenticule of the plurality of lenticules comprises a cylindrical portion and a convex lens on an upper surface of the cylindrical portion,
- the convex lens has a convex surface that faces away from the light source unit,
- a side surface of the cylindrical portion comprises an opaque portion, and
- the convex surface of the convex lens of a specific lenticule of the plurality of lenticules is deviated from a center of the specific lenticule.
A lenticular lens, comprising:
- a plurality of lenticules, wherein
- each lenticule of the plurality of lenticules comprises a cylindrical portion and a convex lens on an upper surface of the cylindrical portion,
- the convex lens has a convex surface that faces away from a plurality of light sources,
