A leaf-filtered sunlight simulation control device includes a plurality of light sources, a single lens, and a leaf-filtered sunlight light source control module to control positions of the plurality of light sources. The leaf-filtered sunlight light source control module controls the positions of the plurality of light sources so that F<A is satisfied, where F is a focal length of the lens and A is a distance from a center axis of the lens to each of the light sources.

An air conditioner includes a housing including an illumination opening at a position viewable by a user; a blower provided in an airflow path connecting an inlet and outlet; a light emitter provided in the housing viewable through the illumination opening and including a light incident portion to receive light emitted from a 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 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. The at least one light extractor is provided in the airflow path.

Lighting device, air conditioner, and control system

A communication system capable of preventing unnecessary switching of an energy saving cell between a normal operation state and an energy saving state. An energy saving cell (ES cell) is in a dormant state that is the energy saving state. In this case, when being notified of a wake-up request message from a communication terminal device (UE), the ES cell executes access restriction control to judge whether the UE can access its own cell. If judging that the UE can access its own cell, the ES cell switches on its own cell and shifts from the dormant state to an active state that is the normal operation state.
