[0014]

Embodiments of the present invention will be described with reference to the drawings. (First Embodiment) As shown in FIG. 1, a plurality of illuminating lamps 12 composed of discharge lamps such as fluorescent lamps are arranged on a ceiling of a passage 11 such as a corridor or an underground mall, for example, in two rows along the passage 11. Each of the illumination lamps 12 can be individually turned on and off by the illumination control device 13.
The lighting control device 13 normally controls each of the lighting lamps 12 to be turned off, and performs control for turning on the corresponding lighting lamps 12 for a certain time in accordance with the passage of a person 14 or an object moving on the passage 11. To save energy.

The illumination control device 13 measures a position sensor 15 as position measuring means for measuring the position of a person 14 or an object moving on the passage 11 and a moving speed of the person 14 or the object moving on the passage 11. A moving speed sensor 16 as moving speed measuring means is connected. As the position sensor 15, for example, a transmission-type sensor that detects attenuation or interruption of an ultrasonic beam generated by an object passing through a transmitter and a receiver, or a reflection-type sensor that detects a reflected wave from an object. Although there is a thing, here, the thing of the reflection type is used. The moving speed sensor 16 uses an ultrasonic wave and utilizes the Doppler effect of a reflected wave from a person or an object, and detects a moving speed and a moving direction from a difference between a transmission frequency and a reflected wave frequency. You are using

The relationship between a person or an object moving in the passage 11 and the lighting timing of the illumination lamp 12 is, for example, as shown in FIG. 2, when the person 14 is moving in the direction of the arrow in FIG. That the person 14 is at the x point
5 is measured, and the moving speed sensor 16 measures that it is moving at a speed v in the direction of the arrow, for example,
Assuming that the lighting sequence time required for the lighting lamp 12 to light from start-up is ts, the lighting lamp 12 to start lighting is
Is an illuminator arranged at a position xexp = x + v · ts away from the local point. That is, by starting the lamp 12 at the position xexp at the present time,
When the person 14 reaches that position xexp, the illuminator 12 will just light up. After passing through the position xexp, the illuminating lamp 12 is turned off after a certain period of time.

As described above, the position of the person 14 is predicted from the current position x, the moving speed v, the moving direction, and the lighting sequence time ts of the illuminating lamp 12, and
Since the position of the illuminating lamp 12 to be started is determined, the illuminating lamp 12 can be reliably turned on at the timing when the person 14 passes under the illuminating lamp 12.

The illumination lamp 12 directly above the moving person 14
Only turning on only the lighting may cause insufficient lighting.
In such a case, the range is determined, and the lighting of the illumination lamps 12 in this range is controlled.

For example, as shown in FIG. 3, when the person 14 is moving in the direction of the arrow in FIG.
The position sensor 15 measures that the user is at the point, and the moving speed sensor 16 detects that the user is moving at the speed v in the direction of the arrow.
For example, if the lighting sequence time required for the lighting lamp 12 to light up from the start is ts, the position xexp of the lighting lamp 12 to start lighting is separated from the local point by xexp = x + v · ts. It is an illuminator that is placed at a different position.

The range for illuminating the front of the person 14 is x
Assuming that f.sub.2 and the range for illuminating the rear side are set to x.sub.b, when the person 14 moves from the position x to the position x.sub.exp, the front end position x.sub.exp-f of the front lighting lamp 12 to be turned on is x.sub.exp-f =
x + v · ts + xf, and the rear lighting lamp 1 to be turned on
2 rear end position xexp-b is xexp-b = x + v · ts + x
b.

The rear illumination range is set to be narrower than the front illumination range. In other words, it is necessary to illuminate to a certain point because the front is the direction to move from now on,
This is because the rear side is a passing position, and it is only necessary that a range in which the driver does not feel uneasy when looking back is bright.

The current position x, moving speed v, and moving direction of the person 14 moving in this way, the lighting sequence time ts of the illuminating lamp 12, the range xf for illuminating the front, and the range xb for illuminating the back are Since the moving position of the person is predicted and the range of the illuminating lamp 12 to be started is determined, when the person 14 reaches a certain position, the front end position xexp-f based on that position is always used. The illuminating lamps 12 in the range up to the rear end position xexp-b are illuminated, so that a certain range can be illuminated around a constantly moving person. , Its front and back are also brighter, safer for moving people,
Comfort can be improved.

When the person 14 moves along the passage 11,
They rarely move at a constant speed, and take various actions such as stopping on the way, walking in the opposite direction, and running. For this reason, an error occurs if the predicted movement position is simply obtained from the movement speed measured only once.
In order to reduce such an error, it is necessary to repeat sampling as needed for the movement of the person, and to measure the movement speed each time to correct the predicted movement position.

Therefore, the accuracy of the predicted movement position of the person 14 can be increased by increasing the number of samplings. However, since it is actually required to increase the speed of the system, there is a limit to increasing the number of times of sampling. Therefore, an error function g (v) with respect to the speed is defined in consideration of an increase in the error of the predicted position when the moving speed is high. Since the error function g (v) takes a larger coefficient as the moving speed is higher,
Basically, it becomes a graph rising to the right as shown in FIG.

Therefore, by using the error function g (v) to correct the front end position and the rear end position, the illumination range is changed according to the speed. That is, person 14
Moves from the position x to the position xexp at the speed v, the tip position xexp-f of the front lighting lamp 12 to be turned on is defined as xexp-
f = x + v · ts + xf · g (v), and the rear end position xexp-b of the rear illuminating lamp 12 to be turned on is expressed as xexp-b = x + v ·
ts + xb · g (v).

Thus, even when a person moves at various speeds, it is possible to reliably illuminate a certain range before and after the person always moving. Therefore, also in this case, not only the position where the person passes, but also the front and rear thereof become bright,
Safety and comfort for moving people can be improved.

(Second Embodiment) This embodiment describes a case where a specific place such as an intersection is present in a passage. In addition, as a specific place, there is a place with a corner or a sign. As shown in FIG. 5, for example, a crossroad 17 is provided in the middle of the passage 11 as an intersection, and a plurality of illuminating lights 12 are also arranged on the ceiling of the crossroad 17. At the center of the ceiling of the crossroad 17, the position sensor 1 described above is provided.
5 and the same sensor 18 as the moving speed sensor 16 are arranged.

The illuminating lamps 12 arranged at the intersection 17
Is controlled to be constantly lit, and the illuminating lamps 12 arranged in the passages 11 other than the intersection 17 are controlled to be constantly lit in a thinned state. The illuminating lamps 12 which are turned off at this time are described above. Lighting control similar to that of the first embodiment is performed. That is, the intersection 17 is a key place in the passage 11, and it is desirable that the intersection 17 is always bright. In addition, in the other passages 11 except the intersection 17, it is preferable to turn off all lights in order to save energy, but it is desirable to maintain a certain level of brightness for the environment. From such a viewpoint, control is performed to turn on only a part of the illuminating lamps 12 arranged in the other passages 11 except for the intersection 17 at a timing at which a person passes.

FIG. 6 is a diagram showing an example of a lighting circuit when a fluorescent lamp is used as the illuminating lamp 12 and a lighting control device for controlling the lighting circuit. Here, one lighting lamp will be described as an example. First, the structure of the lighting circuit will be described. A smoothing capacitor 22 is connected to a DC power supply 21 obtained by rectifying a commercial AC power supply, and a half-bridge type high-frequency inverter circuit 23 is connected to the smoothing capacitor 22. The lighting lamp 12 is connected to the terminal. This lighting circuit is integrated with the lighting lamp 12a as a lighting fixture. In addition, 2
4 is a choke coil, and 25 is a preheating capacitor.

Further, the lighting control device is provided with a human feeling register 2.
6 and a long-term control register 27, each bit of each register 26, 27 corresponding to each of the lamps 12 arranged in the passage 11 and the crossroads 17. In the long-term control register 27, 1 is set to a bit corresponding to an illuminating lamp that is always turned on, and 0 is set to bits corresponding to other illuminating lamps. Also,
At the initial stage, all bits are set to 0 for the human feeling register 26, and when the sensor 18 determines the lamp to be started by measuring the position and moving speed of the moving person, The corresponding bit is set to 1.

The bit corresponding to the illumination lamp 12a of the human feeling register 26 and the long-term control register 27
The output of the bit corresponding to the illuminating lamp 12a is output via a logical OR circuit 28 to a start / on / off sequence controller 29.
To supply. The start / light / light-off sequence control unit 29 controls on / off driving of each of the switching elements 31 and 32 of the inverter circuit 23, and any one of the corresponding bits of the human feeling register 26 and the long-term control register 27. Is 1, the starting sequence is started and each of the switching elements 31 and 32 of the inverter circuit 23 is started.
Is started, and the illumination lamp 12a is turned on after the lapse of the sequence time ts.

When the corresponding bits of the human feeling register 26 and the long-term control register 27 are both 0, a light-off sequence is started to stop the switching operation of each of the switching elements 31 and 32 of the inverter circuit 23, and 12a is turned off. Although the case of one lamp has been described here, the lighting circuit, the OR circuit 28, and the starting / lighting / lighting-out sequence control unit 29 are provided individually for all the lighting lamps.

Accordingly, in this control device, when the sensor 18 measures the position, the moving speed, and the moving direction of the person moving on the passage 11, and determines the illuminating lamp 12 to be started, the illuminating lamp 1
The corresponding bit of the human feeling register 26 corresponding to “2” is set to “1”.
Performs control to start the start of the corresponding lamp 12, and after a certain period of time when a person has passed the position of the lamp 12, the corresponding bit is returned to 0, thereby starting, lighting, The turn-off sequence control unit 29 controls the corresponding lamp 12 to turn off.

As described above, the intersection 17 is located in the middle of the passage 11.
For example, when there is a specific place, the lighting lamp 12 arranged in the specific place is always turned on to illuminate the specific place constantly, and the passage 11 other than the specific place is thinned out to save energy. When a person or an object moves along the passage 11, the lighting lamp 12 in an unlit state positioned above according to the movement of the passage 11
By turning on the illumination lamps 12 before and after that, sufficient illumination can be provided.

(Third Embodiment) This is a case where a plurality of persons 14 move in the passage 11 as shown in FIG. 8, for example, four persons relatively harden and move in the direction of the arrow in the figure. , The position sensor 15 measures the positions of these persons 14, and the moving speed sensor 16 calculates the overall average moving speed v.
Is measured.

Now, the position of the first person is xwf, the position of the last person is xwb, and the range for illuminating the front of the person 14 is xwf.
f, and the range for illuminating the rear is set to xb, the tip position xexp-f of the illuminating lamp 12 to be turned on is xexp-f =
xwf + v · ts + xf · g (v), and the rear end position xexp-b of the rear illumination lamp 12 to be turned on is xexp-b = xwb +
v · ts + xb · g (v).

In order to perform this control, the long-term control register 27 and the OR circuit 28 are omitted in FIG. 6 and the start / light-on / light-off sequence controller 29 is controlled only by the bits of the human feeling register 26. Good. And
The bit setting control for the human feeling register 26 is shown in FIG.
This is performed based on the flowchart shown in FIG.

In the control shown in FIG. 7, first, in S1, initial conditions are set. That is, the lighting sequence time ts of the illuminating lamp 12, the front range xf to be illuminated, the rear range xb to be illuminated, the error function g (v) for the moving speed, and the like are set. Subsequently, in S2, the passage 11 by the position sensor 15
Perform zone scanning inside to measure the position of a moving person. Then, at S3, the position x of the foremost person
The information of wf and the position xwb of the last person is acquired.

Subsequently, in S4, the speed of the moving person 14 is measured by the moving speed sensor 16, and based on the measured result, the average moving speed v of the moving person 14 is determined in S5. Is calculated. Then, in S6, the tip position xexp-f of the illuminating lamp 12 to be turned on is calculated as xexp-f = xwf + v · ts.
+ Xf · g (v), and the rear end position xexp-b of the rear illuminating lamp 12 to be turned on is xexp-b = xwb + v ·
ts + xb · g (v)

Subsequently, in S7, the position xexp-f and the position xexp
The bit of the human feeling register 26 corresponding to the lamp 12 between exp-b and exp-b is set to 1. The bit of the human feeling register 26 corresponding to the illuminating lamp 12 that does not fall within this range is set to 0.
Set to. Thus, the position xexp-f and the position xexp-b
The operation of the lighting / lighting / lighting-out sequence control unit 29 corresponding to the lighting circuit of the illumination lamp 12 between them starts, and the illumination lamp 12 starts.

Subsequently, in S8, it is checked whether or not the position of the person predicted at the time of the previous measurement matches the position of the person measured by the current position sensor 15, and if they match, no change is made. If there is a slight deviation, the parameter of the error function g (v) for the speed is changed. If they are completely different, all the bits of the human feeling register 26 are set to 1 and all the illuminating lamps 12 in the passage 11 are turned on so that no inconvenience occurs.

As described above, when a plurality of persons 14 pass through the passage 11 collectively, appropriate illumination can be achieved by expanding the illumination area while considering the whole as one. Passage 1
1 Many people are moving, and when viewed from the sensor, they are overlapping and the measurement of the front or rear position is uncertain, or the person goes beyond the specified distance in the passage. When the vehicle is moving in a dispersed manner, it is determined that it is not possible to perform control to specify and turn on the illumination lamps 12, and at this time, all the illumination lamps 12 overlooking the passage 11 are turned on. Thereby, appropriate illumination can be performed.
