The human body detection signal from 5h ... is input to the control unit 7,
The control signal from the control unit 7 is the lighting fixtures 6a, 6b, 6c,
6d, 6e, 6f ... and sent to the lighting fixtures 6a, 6
b, 6c, 6d, 6e, 6f ... Are individually controlled. That is, the staircase part 1, the staircase part 2, and the landing part 3 are used as the basic unit areas of the human body detection position and the target position to be illuminated, respectively, and the human body detection sensor 5 detects that there is a person in a certain unit area. In this case, the unit area in which it is determined that there is a person, a plurality of unit areas counting upward from the unit area, and a plurality of unit areas counting downward are illuminated by the lighting fixture 6 with high illuminance and are not applicable. The control unit 7 controls the lighting unit 6 to illuminate other unit areas with low illuminance.

Concretely, now, in FIG.
When there is a person in b, the person in the staircase 1b is detected by the human body detection sensor 5d. In this case, when the human body detection signal from the human body detection sensor 5d is input to the control unit 7, it is determined that a person is present in the staircase room 1b by the determination means provided in the control unit 7 based on the signal, and the staircase is detected. It is determined that the room 1b is a unit area in which a person is present, and a plurality of (two in the embodiment) unit areas (that is, the staircase 2b and the landing 3a) are counted upward from the staircase 1b and the staircase 1b. And a plurality of (two in the embodiment) unit areas (that is, the staircase portion 2c and the landing portion 3b) below the staircase portion 1b to sufficiently secure the light and perform high-illuminance lighting. 6
It is controlled by a control signal from the control unit 7 so that a, 6b and 6c are turned on 100%.

Next, when the person moves to the staircase 2c, the human body detection sensor 5e detects the presence of the person on the staircase 2c, and the human body detection signal from the human body detection sensor 5e is input to the control section 7. Based on the signal, the control unit 7 determines that there is a person in the staircase 2c, and thus the staircase 2c is determined to be a unit area in which a person exists, and the staircase 2c and a plurality of upper stairs 2c are counted. (Two in the embodiment) unit areas (that is, stair room 1b and stair 2b), and a plurality (two in the embodiment) of unit areas (that is, landing 3b and stair) below the stair 2c. 2d), in order to secure sufficient light and to perform high-intensity illumination, lighting equipment 6a,
It is controlled by a control signal from the control unit 7 so that 6b, 6c and 6d are turned on 100%. At this time, lighting equipment 6
Although a, 6b, and 6c are the same as the previous time, the lighting fixture 6d fades in a certain time from 50% lighting to 100% lighting in a low illuminance state when no person is present, for example, in about 1.0 second. It is controlled by the control unit 7 so as to be turned on. For this reason, the control unit 7 is provided with timer means 7a.

Next, when a person moves to the staircase 3b, the human body detection sensor 5f detects the presence of a person in the landing section 3b, and the human body detection signal from the human body detection sensor 5f is input to the control section 7. Based on the signal, the control unit 7 determines that there is a person in the landing unit 3b, and thus the landing unit 3b is determined to be a unit area in which a person exists, and the landing unit 3b
And a plurality above the landing section 3b (2 in the embodiment).
Unit area (ie staircase 2c, staircase room 1b)
And a plurality below the landing section 3b (2 in the embodiment).
Unit area (that is, staircase 2d, staircase room 1c)
In order to secure a sufficient amount of light and to illuminate with high illuminance, the control signals from the control unit 7 are controlled so that the lighting fixtures 6b, 6c, 6d are turned on 100%. At this time, since the lighting fixture 6a is not necessary, a certain delay time (for example, 1
After 100% lighting within 10 seconds (that is, 10 of the lighting fixture 6a)
10% continues for 1 second even after 0% lighting is no longer needed
After being lit for 0%), it is controlled by the controller 7 so as to fade out over a low illuminance, for example, 50% lighting for a certain period of time (for example, 3 seconds).

Next, when a person moves to the staircase 2d, the human body detection sensor 5g detects the presence of the person on the staircase 2d, and the human body detection signal from the human body detection sensor 5g is input to the control section 7. Based on the signal, the control unit 7 determines that there is a person in the staircase portion 2d, and thus the staircase portion 2d is determined as a unit area in which a person exists, and the staircase portion 2d and a plurality of upper stairs portions 2d are counted. (Two in the example) unit areas (that is, landing section 3b, staircase section 2c), and plural (two in the example) unit areas (that is, staircase room section 1c, staircase section) below the staircase section 2d. In order to secure a sufficient light with 2e) and perform high-intensity illumination, the lighting fixture 6c,
It is controlled by a control signal from the control unit 7 so that 6d and 6e are turned on 100%. At this time, the lighting fixture 6e fades in and lights up 100% like the lighting flaw 6d described above, and the lighting fixture 6b fades out like in the lighting fixture 6a described above to turn on low illumination, for example, 50% lighting. Is controlled by the control unit 7.

Here, the lighting equipment 6 installed in the landing section 3 is the landing section 3 concerned and the upper and lower stairs 2 (for example, the lighting equipment 6a installed in the landing section 3a, the landing section 3a, the stairs section). The light distribution is such that 2a and the staircase portion 2b) can be sufficiently illuminated. Further, the lighting fixture 6 installed in the staircase part 1 has a light distribution that can sufficiently illuminate at least the staircase part 1, but sufficiently illuminates the staircase part 1 and the upper and lower staircase parts 2 connected thereto. A light distribution that can be performed is also acceptable.

In the above embodiment, the low illuminance state is controlled by stepwise dimming control such as dimming 50%. However, for example, if the lighting fixture 6 is a 40W 2 lamp lighting fixture, the high illuminance is high. It is also possible to perform thinning lighting control such that both light up in the state and only one light up in the low illuminance state. Next, another embodiment of the present invention will be described in detail with reference to FIG. In this embodiment, the lighting equipment 6 installed in the landing section 3 has a light distribution that can sufficiently illuminate the brightness of the landing 3 and the upper and lower stairs 2 connected to it, and the staircase The lighting fixture 6 installed in the section 1 has a light distribution that can sufficiently illuminate the brightness of the staircase room 1 and the upper and lower staircases 2 connected thereto. Then, for example, the lighting fixture 6a installed in the landing section 3a includes a human body detection sensor 5 capable of detecting the landing section 3a, the staircase section 2a, the staircase room section 1a, the staircase section 2b, and the staircase room section 1b. It works together. Further, the lighting fixture 6b installed in the staircase part 1b works in conjunction with the human body detection sensor 5 capable of detecting the landing part 3a, the staircase part 2a, the staircase part 1b, the staircase part 2b, and the landing part 3b. There is. Similarly, the lighting fixtures 6 respectively installed in the other landing section 3 and the other staircase room section 1 are interlocked with the human body detection sensor 5 for detecting the unit area of the corresponding staircase. In this case, for example, in the case of the lighting fixture 6a, the human body detection sensor 5a is used for the stair room 1a and the staircase 2
a, the landing section 3a is detected, and the human body detection sensor 5b is set to detect the landing section 3a, the staircase section 2b, and the staircase room section 1b. And the lighting fixtures 6a, 6b, 6c,
6d, 6e, and 6f are in a low illuminance state of 50% lighting, for example, if the human body detection sensor 5 linked to each lighting fixture 6 does not detect a human body at all.

Now, a certain unit area, for example,
When a person is present in the staircase room 1a, the human body detection sensor 5a detects the human body, so the detection signal is input to the control unit 7,
The lighting fixture 6a is 100% by the control signal from the control unit 7.
Light. Here, since a human body detection sensor 5a, 5b, 5c detects when a person enters the landing section 3a from the staircase 2a, the human body detection signal from the human body detection sensor 5a, 5b, 5c is input to the control unit 7. The lighting devices 6a and 6b are turned on 100% by the control signal from the control unit 7. Also, when a person enters the staircase room 1b from the staircase 2b,
Since the human body detection sensors 5b, 5c, 5d, and 5e detect, the human body detection signals from the human body detection sensors 5b, 5c, 5d, and 5e are input to the control unit 7, and the lighting device 6a is controlled by the control signal from the control unit 7. , 6b, 6c light up 100%. When a person enters the staircase portion 1b from the staircase room 1b, the human body detection sensors 5d and 5e detect the human body detection sensors 5d and 5e, and the human body detection signals from the human body detection sensors 5d and 5e are input to the control unit 7 and controlled by the control unit 7. Lighting equipment 6b, depending on the signal,
6c lights up 100%. At this time, since the human body detection sensors 6a and 6b which are interlocked with the lighting fixture 6a do not detect the human body, the lighting fixture 6a is kept at a certain time, for example, 3
After the delay time of 0 seconds, the control unit 7 controls so as to perform stepwise dimming to 50% lighting. In addition, when a person moves from the staircase portion 2c to the landing portion 3b, the human body detection sensors 5d, 5
e, 5f, 5g, the human body detection signals from the human body detection sensors 5d, 5e, 5f, 5g are input to the control unit 7, and the lighting devices 6b, 6c, 6d are controlled by the control unit 7. It lights up 100%.

The above is the case of getting down the stairs 4,
When going up the stairs 4, this is reversed, so that each human body detection sensor 5 detects and the necessary illumination can be obtained. As described above in FIG. 5, the “lighting equipment 6a installed in the landing part 3a is a human body capable of detecting the landing part 3a, the staircase part 2a, the staircase part 1a, the staircase part 2b, and the staircase part 1b. The lighting fixture 6b installed in the staircase 1b in conjunction with the detection sensor 5 is a human body capable of detecting the landing part 3a, the stairway part 2a, the staircase part 1b, the stairway part 2b, and the landing part 3b. The lighting fixtures 6 installed in the other landing section 3 and the other staircase room section 1 in the same manner as the detection sensor 5 are also interlocked with the human body detection sensor 5 that detects the unit area of the corresponding staircase. Another example showing the arrangement of the human body detection sensor 5 and the lighting fixture 6 capable of satisfying the condition (condition 1) is shown.

In this embodiment, the lighting fixture 6a is provided with the human body detection sensor 5 while keeping the condition shown in the condition 1 above.
If any one of a and the human body detection sensors 5a, 5b, 5A detects the human body, the lighting fixture 6a is turned on 100%. Further, the lighting fixture 6d is configured to turn on 100% of the lighting fixture 6d when any of the human body detection sensors 5d, 5g, 5D detects the human body. Here, although not shown, the lighting fixtures 6b, 6c, 6f
Also has 3 human body detection sensors 5 similarly,
The lighting fixtures 6b, 6c, 6f are controlled.

In this embodiment, as described above, the lighting device 6 is used.
In order to illuminate the stairs by arranging several devices provided with three human body detection sensors 5 continuously on the stairs 4, in this case, the lighting fixture 6, the human body detection sensor 5, and the control unit are provided for each device. 7 may be provided. Next, FIG.
Another embodiment of the present invention will be described based on FIG. In this embodiment, as shown in FIG. 6, the lighting equipment 6 is the landing section 3
It is installed only on the side. These luminaires 6 have a light distribution enough to be sufficiently bright to the upper and lower staircases 1 (for example, in the case of the luminaire 6a, the staircase 1a, the stairs 2a, the landing 3a, the stairs 2b, There is a light distribution that can brighten the staircase 2b). The human body detection sensors 5a and 5b are interlocked with the lighting fixture 6a. When either of the human body detection sensors 5a and 5b detects a human body, a signal is input to the control unit 7, and the control unit 7 turns on the lighting fixture 6a 100%. To be controlled. Similarly, when one of the human body detection sensors 5c and 5d detects a human body, a signal is input to the control unit 7, and the control unit 7 controls the lighting fixture 6c to turn on 100%. That is, the staircase 2
a, the lighting fixture 6a that detects the presence of a person in the landing part 3a and the staircase portion 2b by the human body detection sensor 5, and the lighting fixtures 6a and 6c when the presence of a person in the staircase compartment 1b is detected by the human body detection sensor 5. , Staircase part 2c, landing part 3b, staircase part 2d
When the human body detection sensor 5 detects that there is a person in the vehicle, the control unit 7 controls the lighting device 6c so that the lighting device 6c lights up 100%. These lighting fixtures 6 are also controlled to shift to 50% lighting after a certain delay time, for example, 3 minutes after no person is detected after 100% lighting.

Next, another embodiment will be described. That is, in the configuration as shown in the embodiment of FIG. 1, when the signals from the human body detection sensors 5b, 5a, 5c, 5d, and 5e are as shown in FIG.
Human body detection sensor 5b → 5a → 5c → 5
When the human body is detected by the human body detection sensor 5e while being detected in the order of d → 5e (here, for example, the human body detection sensors 5b, 5a, 5c, and 5d in FIG. 7 and thereafter have no outputs). A person can walk up the stair room 1a, the stairway 2a,
When you are not in the landing 3a, staircase 2b, or staircase room 1b,
That is, if the human body detection sensors 5a, 5b, 5c, and 5d are not detecting the human body, the human body movement direction determination means 8 provided in the control unit 7 determines that the person has moved from top to bottom, and based on this, The lighting device 6b, 6c, 6d is turned on 100% by the signal from the control unit 7, and the lighting device 6a which is turned on 100% in the embodiment shown in FIG.
The control is performed so as to shift to 0% lighting. Even when a person moves on the stairs 4 from the bottom to the top, the movement direction is similarly determined by the human body movement direction determination means 8. As described above, in this embodiment, when the detection signal of the human body from the human body detection sensor 5 is input to the control unit 7, the movement direction determination unit 8 provided in the control unit 7 determines the movement direction of the human body to detect the human body. The unit area on the traveling direction side of the human body determined by the human body movement direction determination means 8 from the unit area which is the position is the lighting fixture 6
Therefore, the control unit 7 controls the number of high-illuminance illumination of the unit area on the opposite side of the moving direction of the human body to the high-illuminance illumination. Here, in the above example, as a direction for omitting the illumination of the lighting fixture 6a, the delay time of the lighting fixture 6a is set shorter than that when the moving direction of the human body is undetermined. When the moving direction of the human body is determined as described above, the lighting fixture 6a is turned on by 50%. When the moving direction of the human body is determined as described above, the lighting fixture 6a is turned on, for example, 70%. It is possible to adopt, for example, fading out (for example, up to 50% lighting) over a long period of time from the time when the moving direction of the human body is determined, for example, one minute.

Next, still another embodiment of the present invention will be described in detail with reference to FIGS. 8, 9 and 10. In this embodiment, a human body detection sensor 5 (for example, in the case of the human body detection sensor 5a, a staircase room 1a and a landing section 3a, which detects the upper staircase section 1, the lower landing section 3 and the staircase section 2 therebetween. And staircase 2a), lower staircase room 1 and upper landing room 3

And the lighting fixture 6b illuminate the staircase 1b, the staircases 2b and 2c, and the landings 3a and 3b. Therefore, for example, in the staircase portion 2b, it is set so that the required light cannot be obtained unless both of the lighting fixtures 6a and 6b are turned on 100%.

Here, in the embodiment of FIG. 8, when there is a person in the staircase 1c, the human body detection sensors 5d and 5e detect the human body, and the lighting device 6 is controlled by the control signal from the control unit 7.
100% of b, 6c, 6d, 6e and 6f are turned on. When there is a person on the staircase 2e, that is, when only the human body detection sensor 5e detects the human body, the lighting fixtures 6c, 6d, 6e,
6f is turned on 100%. In addition, when there is a person in the landing section 3c, that is, the human body detection sensors 5e and 5f detect the human body, and the lighting devices 6d and 6 are controlled by the control signal from the control section 7.
e, 6f and 6g are turned on 100%. When there is a person on the staircase 2f, that is, when only the human body detection sensor 5f detects the human body, the lighting fixtures 6d, 6e, 6f, 6g are set to 100.
%Light. When a person is present in the staircase 1d, the human body detection sensors 5f and 5g detect the human body, and the lighting devices 6d, 6e, 6f, 6g, and 6h are turned on by a control signal from the control unit 7.
It lights up at 00%. The same control is performed thereafter.

Next, another example of control in the embodiment of FIG. 8 will be described. That is, in FIG. 8, when only the human body detection sensor 5e detects the presence of a person on the staircase 2e, the lighting fixtures 6b, 6c, 6d, 6e, 6f, 6g are set to 10
Lights up 0%. When only the human body detection sensor 5f detects that there is a person on the stairs 2f, the lighting fixtures 6d, 6
e, 6f, 6g, and 6h are turned on 100%. Further, when only the human body detection sensor 5h detects that there is a person on the staircase 2h, the lighting fixtures 6d, 6e, 6f, 6g, 6
100% of h and 6i are lit. The same applies hereinafter. Then, for example, when both of the human body detection sensors 5e and 5f detect a human body, that is, when there is a person in the landing section 3c, the lighting fixtures 6b, 6c, 6d, 6e, 6f, 6g,
6h lights up 100%.

Here, FIGS. 9 and 10 show an example in which the mounting position of the human body detecting sensor 5 is different from that of the embodiment of FIG. 8, but the human body detecting sensor 5 detects the human body and the illumination based on the detection of the human body. The control relationship with the instrument 6 is the same as that of the embodiment shown in FIG. By the way, in the present invention, the switching of the illuminance of the lighting fixture 6 is performed, for example, when the human body detection sensor 5 detects the movement of a person from the staircase 1 to the staircase 2 or from the landing 3 to the staircase 2. When the human body detection sensor 5 detects the movement of a person from the staircase portion 2 to the staircase portion 1 or from the staircase portion 2 to the landing portion 3, the illuminance of the luminaire 6 is controlled. The control unit 7 controls the switching. Of course, when the human body detection sensor 5 detects the movement of a person from the staircase part 1 to the staircase part 2 or from the landing part 3 to the staircase part 2 and from the staircase part 2 or the staircase part 1 to the landing part 3. The illuminance of the lighting fixture 6 may be switched in any case when the human body detection sensor 5 detects the movement of the person.

Next, still another embodiment of the present invention will be described. The present embodiment is characterized in that an illuminance detection unit 9 is provided on the stairs 4 in addition to the configurations of the respective embodiments shown in FIGS. 1 to 10 described above. FIG. 11 is a control block diagram showing an example in which the illuminance detector 9 is provided. The illuminance detector 9 is configured to detect the brightness by using a light receiving element such as a CdS element or a photodiode, and a plurality of illuminance detectors 9a, 9b ... 9h ... are arranged in the vertical direction of the stairs 4. The brightness information such as the illuminance detected by each illuminance detector 9 is input to the controller 7. Here, a plurality of illuminance detectors 9 arranged above and below the stairs 4 can detect each part of the stairs 4 in the vertical direction by one of the illuminance detectors 9 to detect the illuminance of the entire length of the stairs 4. Then, if the illuminance from the illuminance detection unit 9 is equal to or higher than the set value (for example, if it is detected that the illuminance is 500 lux or more due to the entry of daylight from the window), the human body detection sensor 5 detects the human body. For example, 100% of the corresponding part of the stairs 4 (that is, the unit area where it is originally determined that a human body is present in the present invention and a plurality of unit areas above and below the unit area) is lit up, for example. As described above, the control unit 7 controls to perform high-illuminance lighting, but the control unit 7 controls to perform low-illumination lighting such that 100% lighting is switched to 80% lighting. In addition, when the illuminance from the illuminance detector 9 is equal to or higher than the set value, the delay time for maintaining 100% lighting may be shortened. Of course, when the illuminance detection unit 9 is provided and when the illuminance detected by the illuminance detection unit 9 is equal to or lower than the predetermined illuminance, as in each of the embodiments shown in FIGS. When the human body is detected, the corresponding part of the stairs 4 is controlled to be illuminated with high illuminance and the other part is illuminated with low illuminance.

The staircase 4 of the present invention is a so-called zigzag staircase in which the staircase 1, the staircase 2 and the landing 3 are repeatedly arranged in this order, but if the present invention is as shown in FIG. It can also be applied to staircases. That is, in the case of the spiral staircase, the portion indicated by A in FIG. 12 is regarded as the staircase portion 2, the portion indicated by B in FIG. 12 is regarded as the staircase room portion 1 (or the landing portion 3), and the portion indicated by C in FIG. It is regarded as part 3 (staircase part 1), and by doing so, it is considered that the spiral staircase is repeatedly arranged in the order of the staircase part 1, the staircase part 2, and the landing part 3 above and below. The above-mentioned embodiments of the present invention can be applied. Thus, the present invention can be adapted to various stairs by using some of the features of the zigzag stairs.
