And a control unit 32 for outputting a signal to be turned on from the communication unit 33.

The operation of this embodiment will be described below with reference to FIG. The illuminance detection unit 20 is constantly operating, and the control unit 22 determines whether the output of the illuminance sensor 21 is equal to or more than a predetermined value (S1), and when the output of the illuminance sensor 21 is equal to or more than the predetermined value (S1). When the illuminance is larger than the predetermined illuminance), the communication unit 2
The stop signal for stopping the human body detection is transmitted from 3 to the communication unit 33 of the human body detection unit 30. When the stop signal is received by the communication unit 33, the human body detection unit 30 stops the detection of the human body by the human sensor 31 (S2). The human body detection unit 30 may stop the operation of both the human sensor 31 and the control unit 22 when the stop signal is received, or may stop the operation of the control unit 22 only. You may. Therefore, power consumption in the human body detection unit 30 can be suppressed, and power can be saved.

On the other hand, in S1, when the control unit 22 determines that the output of the illuminance sensor 21 is smaller than a predetermined value,
A start signal for starting human body detection is transmitted from the communication unit 23 to the communication unit 33 of the human body detection unit 30. When the activation signal is received by the communication unit 33, the human body detection unit 30 starts human body detection in the human body detection area C of the human body sensor 31 (S3), and when the human body is detected by the human body sensor 31 (S4). ), The control unit 32 transmits the lighting device 10 from the communication unit 33.

Illuminance can be obtained.

The lighting fixture 10 is provided with, for example, a lighting holding time setting section (not shown) and a timer section (not shown) for measuring the time set by the lighting holding time setting section in the lighting apparatus body. In this way, after the light-up signal disappears, the light-off time may be automatically turned off after a light-on hold time set in advance by the light-on hold time setting unit, or the human sensor 31 may detect a human body. After that, the lighting unit 11 may be turned off by transmitting a turn-off signal to the lighting unit 10 after a predetermined time is measured by the timer unit 34. For this reason, in the present embodiment, the lighting load is automatically turned off after a predetermined time has elapsed after the human sensor 31 has stopped detecting the human body. Can be achieved.

When the illuminance L ₁ is referred to as) only slightly smaller than (for example,
In the evening, etc., that is, when the difference in brightness between the outside and the indoor near the entrance door d is small and the outside is slightly darker, the lighting fixture 10
The illumination load 11 is dimmed by the dimming control signal as shown in FIG.

On the other hand, when the illuminance L ₂ is smaller than the illuminance L ₁ by a certain fixed illuminance, that is, when there is a large difference in brightness between the outdoor and indoor areas near the entrance door d (for example, at night), The lighting load 11 of the lighting fixture 10 is controlled by the dimming control signal based on the lighting signal and the turning-off signal as shown in FIG.
The dimming is performed as shown in (b), and the peak value of the illuminance level is smaller than that in FIG.

As shown in FIG. 8D, the peak value of the illuminance level when the light is adjusted and a lighting signal is received is made larger than that in FIG. 8C. Performing such dimming is because if the human eyes are used to the bright outdoors outdoors, such as during the daytime, if they enter the indoors, they must enter a dark place for a moment unless the interior is bright enough. Because it takes a while for the eyes to get used to the surroundings.

In the case of FIGS. 8C and 8D, the illuminance level gradually decreases even if no light-off signal is transmitted from the human body detecting section 30. And Thus, in this embodiment, the illuminance detecting unit 20 _1, 20 ₂ is placed people at distant positions respectively, compares the detected illuminance in each illumination detection unit 20 _1, 20 ₂ based on the comparison result Since the dimming control signal is transmitted to the lighting fixture 10, it is possible to prevent the area in front of the eyes from suddenly becoming brighter or darker.
