Provided is a lighting device capable of manipulating a wider range of parameters to reproduce various light sources. A light source unitincludes, 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 lensincludes 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.

Lighting device

The present technology relates to a light-shielding device and a light-shielding method which make an object that is meant to be invisible to human beings enter a state in which the object is hidden so as to be invisible to eyes, or make an object that is meant to be visible enter a state in which the object is visible to eyes in correspondence with biological information. A light-shielding wall, which partitions two spaces and includes a plurality of panels capable of being controlled to a transmitting state in which light is transmitted or a light-shielding state in which light is shielded, is used as a window, an orientation of a face of a user who is sleeping is detected as biological information, and the light-shielding wall is controlled so that the user is capable of visually recognizing light when it reaches an alarm setting time.

Light-shielding device and light-shielding method

Provided is a material-fixing substrate that does not have to use copper as a catalyst because the substrate-bonding site includes a cyclic alkyne to form a covalent bond with a surface of the substrate, and therefore that can reduce damage to a cell, for example, in a case where a to-be-fixed material is the cell. The material-fixing substrate has a to-be-fixed material fixed thereon via a material-fixing agent. The material-fixing agent includes: a substrate-bonding site that forms a covalent bond with a surface of the substrate and includes at least a cyclic alkyne; a hydrophilic site that is bonded to the substrate-bonding site; a light-responsive site that is bonded to the hydrophilic site and changes the skeleton thereof by irradiation with light; and an attachment site to which the to-be-fixed material is attached.
