The sensor 4 shown in FIGS. 2 and 4 is a sensor that detects surrounding conditions using radio waves. The sensor 4 is a human sensor that detects the presence of a person as part of the surrounding situation.

The sensor 4 is, for example, a radio wave sensor using the Doppler effect. The sensor 4 includes a transmitting antenna that transmits unmodulated continuous wave radio waves (transmission waves) in the microwave band (24 GHz band), and a receiving antenna that receives radio waves reflected by objects (reflected waves). When a transmitted wave is reflected by a person, a frequency difference occurs between the transmitted wave and the reflected wave depending on the person's moving speed due to the Doppler effect. The sensor 4 detects the presence of a person (for example, a person going up and down stairs) based on the frequency difference. The sensor 4 outputs a detection signal to the control device 5 when detecting the presence of a person. Note that the sensor 4 measures the distance to the object that reflected the transmitted wave by transmitting a frequency-modulated transmitting wave from the transmitting antenna, multiplying the received wave received by the receiving antenna by the transmitted wave, and performing phase detection. It may also be a sensor that detects the presence of a person from a distance.

The sensor 4 includes a sensor case 40 and a sensor main body 41 housed in the sensor case 40.

A front surface 400 of the sensor case 40 of the sensor 4 is located adjacent to the diffusion member 8 .

The control device 5 controls the light source unit 3 according to the detection result of the sensor 4. The control device 5 makes the amount of illumination light emitted from the light source 30 smaller than a reference value when the sensor 4 is not detecting the presence of a person, and when the sensor 4 is detecting the presence of a person. The light source unit 3 is controlled so that the amount of illumination light matches the reference value.
