Abstract: A received-light amount measurement system is provided. The received-light amount measurement system includes: a first device that is wearable and obtains a first amount of received light; and a controller that, obtains first information on the first amount of received light from the first device. When the first amount of received light is less than or equal to a first specified value, the controller calculates interpolation information for interpolating the first amount of received light during a time period in which the first amount of received light is less than or equal to the first specified value, and determines the interpolation information as an interpolated amount of received light obtained by the first device.

Abstract: A lighting device includes: a light source switchable between illumination modes; a human detector which detects a person in a detection area in an illumination area of the light source; an ID reader which wirelessly reads an identification stored in an RF tag in a read area corresponding to the detection area; and a controller communicably connected to the light source, the human detector, and the ID reader. The controller obtains from the human detector human detection information indicating that one or more persons are present, obtains from the ID reader one or more identifications read by the ID reader when the human detector detects the one or more persons, and applies one mode of the illumination modes to the light source based on the human detection information and one or more identifications obtained, and the light source performs illumination in the applied mode.

Abstract: An illumination system includes: a seat; a wall; and a sleep control light for controlling sleep, wherein the seat includes a backrest and a seating portion, and makes a transition between a seated state and a lying state when the backrest and the seating portion make a slide movement, the seated state being a state where a minor angle formed between the backrest and the seating portion is a first angle, the lying state being a state where the minor angle is a second angle greater than the first angle, an optical axis of the sleep control light is tilted downward with respect to the horizontal plane, the sleep control light is located behind or above the seat when the seat is in the seated state, and the optical axis of the sleep control light passes through the backrest when the seat is in the lying state.
