摘要： Provided are a diffusive body, an illumination unit and an illumination device that are low-profile and capable of achieving both of sky reproducibility and color unevenness suppression. The diffusive body is a diffusive body that lets first light enter and emits scattered light, wherein a scattering layer (30) that exerts predetermined scattering power on the first light and a transmission layer (40) that passes through the first light are stacked together, the diffusive body has a light incidence surface (f21) that lets the first light enter and a main surface where a first light emission surface (f22) emitting the scattered light is formed, the light incidence surface is formed at an end face forming a first end part of the main surface, the diffusive body functions as a light guide path that makes the entered first light move to and fro between the scattering layer and the transmission layer, the scattering layer includes an optical medium (302) on a nanometer order and generates the scattered light by having the entered first light scattered by the optical medium on the nanometer order, and a correlated color temperature of the scattered light is higher than the correlated color temperature of the first light.

摘要： It is intended to enable switching between a lighting function and a window function, and provide both reproducibility of the sky in using the lighting function and visibility of an opposite space or translucency in using the window function.
A lighting device (200) includes a first light source (10) to emit first light; a diffuser (20) to receive the first light and emits first scattered light; and a frame (300) to support the first light source and the diffuser, wherein the diffuser includes nanoparticles, and guides the received first light, scatters it with the nanoparticles, and emits it as the first scattered light; the diffuser includes an incident surface (f21) to receive the first light, a first surface (f22) on which an emission surface to emit the first scattered light is formed, and a second surface (f23) opposite the first surface; the incident surface is formed at a first edge portion of the diffuser, the frame is opened to expose at least a portion of a region on the first surface of the diffuser in which the emission surface is formed and a region on the second surface corresponding thereto; and a correlated color temperature of the first scattered light is higher than a correlated color temperature of the first light.-

摘要： A lighting unit (100) includes a light source (10) and a diffusive body (12). The light source (10) emits light (Li). The diffusive body (12) includes an incidence surface (13), a diffusive part (12a) and a reflecting surface (16). The diffusive part (12a) guides the light (Lt) and makes the light (Lt) be scattered by nanoparticles (122) into scattered light (Ls). The reflecting surface (16) reflects the light (Lt) guided without being scattered into reflected light (Ll). The incidence surface (13) is formed on an edge part (23a) of the diffusive body (12). The reflecting surface (16) is formed in an edge part (23b) where the light (Lt) guided through the diffusive part (12a) reaches. The scattered light (Ls) is emitted from a region (14a). The reflected light (Ll) is emitted from a region (14b) different from the region (14a). A correlated color temperature of the scattered light (Ls) is higher than that of the light (Li).

摘要： It is intended to improve the spaciousness of a space.
An air conditioner includes a housing including an inlet and an outlet, and an illumination opening at a position viewable by a user in an installed state; a blower provided in an airflow path connecting the inlet and the outlet; a first light source provided in the housing; a light emitter provided at a position in the housing viewable through the illumination opening, the light emitter including a light incident portion to receive light emitted from the first light source and a first light emission portion to emit first light generated from the light and including light simulating natural light; and at least one light extractor provided at at least one position around the light emitter in the housing, the at least one light extractor emitting second light that is part of the light received by the light emitter that reaches an edge portion of the light emitter without being emitted as the first light or second light received from the first light source or a second light source different from the first light source without intervention of the light emitter, toward a space that is outside the housing and faces the illumination opening. The at least one light extractor is provided in the airflow path.-
