Abstract: A light exposure system includes an external apparatus that is placed on a facility and a portable terminal that communicates with the external apparatus, and manages the amount of light which the user is exposed to. Furthermore, the external apparatus transmits information regarding the amount of light which the user is exposed to, to the portable terminal. In addition, the portable terminal includes: a terminal-side controller which receives the information from the external apparatus and calculates the cumulative value of the amount of light from the information, when a communication is established with the external apparatus; and a display that displays the cumulative value calculated by the terminal-side controller.

Abstract: A lighting apparatus includes: a white light source; a blue light source; a reflector layer which reflects light; a light diffuser layer which is light transmissive and disposed on an anterior surface side of the reflector layer; and a scatter panel which is light transmissive and disposed on an anterior surface side of the light diffuser layer to face the light diffuser layer. At least a portion of a gap between the scatter panel and the reflector layer and at least a portion of a gap between the scatter panel and the light diffuser layer change from a first end side to a second end side of the lighting apparatus. The white light source and the blue light source are disposed on the first end side of the lighting apparatus to emit light toward the light diffuser layer and the scatter panel.

Abstract: An illumination apparatus includes: a case having an opening portion; a light source disposed in the case and including a plurality of light-emitting elements; a light diffuser which is disposed in the opening portion, and diffuses and transmits light emitted from the plurality of light-emitting elements; and a controller that controls light emission from the light source. The controller: controls light emission from the plurality of light-emitting elements to project an image on the light diffuser, the image changing with time; and when changing the light emission from the plurality of light-emitting elements changing the image, controls the light emission from the light source to keep a change in at least one of (i) a light amount, (ii) a color temperature, and (iii) a spectral distribution of light emitted from the illumination apparatus within a predetermined range.

Abstract: A light environment producing apparatus includes: a light source; a light diffuser having a translucency; and a case which houses the light source. In addition, the case has a blue non-mirror finished inner surface which is a light diffusing surface. Furthermore, the light diffusing surface receives light emitted from the light source. The light diffuser is fixed to the case so as to allow passage of light diffused by the light diffusing surface.

Abstract: A light emission apparatus emits light that activates a human body. The light emission apparatus includes a light-emitting module that emits light from a light emission region. The light emission region includes a first light emission region that emits light having a first luminance and a second light emission region that emits light having a second luminance greater than the first luminance. The second light emission region is a different region than the first light emission region. The first light emission region is located in a central region of the light emission region. The second light emission region is peripheral to the first light emission region. The light having the first luminance emitted from the first light emission region has a predetermined wavelength that activates the human body.

Abstract: An illumination apparatus includes a plurality of light emitters, and a light control component that transmits light emitted from the plurality of light emitters. The light control component includes a first diffusion layer and a second diffusion layer. A first perpendicular haze is lower than a first diagonal haze, the first perpendicular haze indicating a diffusion degree of light traveling perpendicular to a light emission surface of the first diffusion layer, and the first diagonal haze indicating a diffusion degree of light traveling diagonal to the light emission surface of the first diffusion layer. A second perpendicular haze is higher than a second diagonal haze, the second perpendicular haze indicating a diffusion degree of light traveling perpendicular to a light emission surface of the second diffusion layer, and the second diagonal haze indicating a diffusion degree of light traveling diagonal to the light emission surface of the second diffusion layer.
