摘要： A cubicle unit includes a first illumination apparatus, a second illumination apparatus, a sensor, and a controller. When a brightness sensed by the sensor is a predetermined brightness or less, the controller causes the second illumination apparatus to emit light having a first color temperature lower than a color temperature of light emitted by the first illumination apparatus. When the brightness sensed by the sensor is greater than the predetermined brightness, the controller causes the second illumination apparatus to emit light having a second color temperature lower than the first color temperature.

摘要： A lighting device includes a power conversion unit, an impedance adjustment unit, a first control unit, and a second control unit. The power conversion unit is configured to convert input power to direct-current power used for a light source. The impedance adjustment unit is formed of a series circuit of a resistor element and a switch element and is coupled to the light source in parallel, relative to the power conversion unit. The second control unit is configured to cause the power conversion unit to operate, for each burst cycle, for an operation period which is not longer than the burst cycle, and increase and reduce the ratio of the operation period to the burst cycle. The first control unit is configured to make the switch element conductive for a predetermined adjustment period which is not longer than the operation period, during the operation period.

摘要： An illumination system includes: a seat in a mobile body; a table to be positioned in front of a passenger when the passenger is seated on the seat; a first light source which illuminates the table; and a second light source which illuminates a region closer to the passenger than to the table. When a distance from the first light source to the table is equal to a distance from the second light source to a virtual irradiated surface, an illuminance on the table irradiated by the first light source is lower than an illuminance on the virtual irradiated surface irradiated by the second light source.
