Abstract:
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.
