Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for controlling lighting equipment installed in a corridor in a building, for example.

[0002]

2. Description of the Related Art Conventionally, as a lighting device for controlling lighting / extinguishing of a plurality of lighting devices installed in a corridor of a building or the like, there is one described in Japanese Patent Laid-Open No. 3-134996.
This lighting device is shown in FIG. 2 and will be described. In FIG.
10 is a side view of the corridor in the building.
Is the ceiling of the corridor, and 12 is the floor of the corridor. On the ceiling 11 of this corridor, a plurality of lighting lamps 13, 14, ... Are arranged at predetermined intervals, and two of the lighting lamps 13, 14 ,.
14 is illustrated. 100 is a lighting device for the illumination lamp 13,
Reference numeral 200 denotes a lighting device for the illumination lamp 14, which is a power source 1 for illumination.
The power of 5 is controlled to supply power to the illumination lamps 13 and 14, respectively. Reference numeral 16 is a power supply line. In the figure, C and D indicate the illumination areas of the illumination lamps 13 and 14, respectively.

FIG. 3 shows the configuration of the lighting devices 100 and 200. This device includes a human body detection unit 20, a lighting control unit 40, and a transmission / reception unit 50. Human body detection unit 20
Has a human body detection sensor 21. The human body detection sensor 21 is, for example, a pyroelectric far-infrared sensor, and generates a detection signal m when it detects a human body. In FIG. 2, a space A surrounded by a dotted line shows a detection range of the human body detection sensor 21, and when a person enters this detection range,
The human body detection sensor 21 generates the detection signal m. This detection signal m is input to the comparison unit 23 through the amplification unit 22. The comparison unit 23 compares the detection signal m with a set value (threshold value), and outputs a human body detection signal M when it is equal to or larger than the set value. In FIG. 2, a space B surrounded by a dotted line indicates a detection range of the human body detection sensor 21 for the lighting installation 200.

The lighting controller 40 is a microcomputer C.
The output state of the comparison unit 23, which includes the PU 41 and the drive unit 42 and generates the human body detection signal M, is monitored, and the transmission command Mx is sent to the timer unit 51 of the transmission / reception unit 50 by a lighting command (low brightness lighting command S ₁ , high brightness). A lighting command S ₂ ) is sent to the drive unit 42. Upon receiving the transmission command Mx, the timer unit 51 generates the drive signal X for a short fixed time. Also, the drive unit 4
2 receives the low-brightness lighting command S ₁ or the high-brightness lighting command S _2, and when the low-brightness lighting command S ₁ , the illumination lamp 13 or 14 is a low-brightness lighting, and when the high-brightness lighting command S ₂ is a lighting, The lamp 13 or 14 is controlled to be turned on with high brightness.

The transmission / reception unit 50 has a transmission unit 52, a transmission antenna 53, a reception unit 54 and a reception antenna 55. The transmission unit 52 performs a transmission operation only while receiving the drive signal X output from the timer unit 51. , And transmits a radio signal Rx via the transmitting antenna 53. The reception unit 54 receives the radio signal R from the lighting device at the front stage or the rear stage through the reception antenna 55, and inputs the reception output to the CPU 41.

Now, the illumination lamp 13 is turned on with high brightness, and the illumination lamp 1
4 is turned on with low brightness. When a person enters the human body detection range A of the human body detection sensor 21 of the lighting device 100 in this state, the human body detection sensor 21 generates a detection signal m, and the detection signal m is above a certain level. The comparison unit 23 generates the human body detection signal M. Upon receiving the human body detection signal M, the CPU 41 sends a transmission command Mx to the timer unit 51. The timer unit 51 starts timing at the same time as generating the drive signal X, and the transmission unit 52 receiving this drive signal X performs a transmission operation for a predetermined time to illuminate the radio signal Rx via the transmission antenna 53. It transmits to the corridor 10 which is a control space. The radio signal Rx is received by the receiving unit 54 of the lighting device 200 via the receiving antenna 55, and the received output is given to the CPU 41. C
The PU 41 decodes that the received output is the transmission signal based on the transmission command Mx from the lighting device 100, and generates the low-luminance lighting command S ₁ for lighting the illuminating lamp 14 at low brightness. Instead of the brightness lighting command S ₁ , a high brightness lighting command S ₂ is input to the drive unit 42 of the lighting device 200, and at the same time, a timer unit (not shown) starts timing. As a result, the illumination lamp 14 is turned on with high brightness.

However, in such a conventional example, the corners other than the straight part of the corridor, that is, the corners that bend into an L-shape, the four corners that intersect in a cross shape, and the corners that bend into a T-shape. No consideration is given to parts or other corridors that intersect one corridor.

[0008]

SUMMARY OF THE INVENTION According to the present invention, when a person walks near a corner other than a straight part of a corridor, or when there is another corridor that intersects with a corridor that is currently walking, the corridor near the intersecting corridor is present. It is intended to provide a lighting system that gives the walking person a sense of security and ensures safety when walking.

For example, in FIG. 4, passages Sa and Sb

Therefore, for example, the present inventors set the illuminance of the horizontal line portion in FIG. 4 to a level substantially equal to or higher than the illuminance of the portion that does not intersect with other corridors in the passage Sa, thereby making the sense of anxiety. Therefore, the present invention provides a lighting system that can realize such lighting.

[0011]

According to the present invention, in order to solve the above problems, the presence of a person is detected in an illumination environment in which another portion adjacent to a straight path exists, and a lighting fixture is turned on. In a lighting system comprising at least one lighting device having a function of causing the lighting device and a plurality of lighting devices that can be controlled by the lighting device to be arranged, when a person is present in the straight path, the lighting device belonging to the straight path is turned on. , When the person's field of view (for example, within 20 m) includes a part of the space at another place adjacent to the straight passage (for example, the space between the straight passage and the adjacent place), the illuminance of the space is It is characterized in that the illuminance is set to be substantially equal to or higher than the illuminance of a portion having no adjacent portion of the straight passage.

Here, the space for setting the illuminance may be, for example, within 5 to 7 m from a person existing in the straight passage, and the illuminance is such that all the lighting fixtures belonging to other locations adjacent to the straight passage are turned on or It may be set by stepwise dimming. As the space for setting the illuminance, an adjacent portion existing closest to the person in the straight passage, an adjacent portion existing in a relatively close place, or, in addition to this, one in the traveling direction of the person in the straight passage. It is conceivable to set it as an adjacent part in the back.

Further, it is preferable to install more luminaires in the vicinity of the intersection of the straight passage and the adjacent portion than in the portion having no adjacent portion of the straight passage. In this case, in order to set the illuminance of a part of the space at another location adjacent to the straight passage to be substantially equal to or higher than the illuminance of the portion not having the adjacent location of the straight passage, the lighting equipment belonging to the adjacent location is turned off. You may let me.

A lighting device 1 used in the lighting system of the present invention.
FIG. 1 shows a schematic configuration of the above. The plurality of lighting fixtures 2 and the plurality of human body detection units 3 are arranged dispersedly in the lighting environment,
It is connected to one control unit 4 via wiring. A setting unit 5 is connected to the control unit 4, and the setting unit 5 arbitrarily sets which lighting fixture 2 is to be turned on according to a detection signal from the human body detection unit 3. Note that at least each of the lighting fixtures belonging to the linear passage and the adjacent portion may be configured by a lighting device having a function of detecting the presence of a person and turning on the lighting fixture.

[0015]

According to the present invention, the adjoining portion existing closest to the person in the straight passage, the adjoining portion existing in a relatively close place, or in addition to this, in the traveling direction of the person in the straight passage. By setting the illuminance at the boundary with the straight passage to be approximately equal to or higher than the illuminance at the portion that does not have the straight passage adjacent to the adjacent location existing in the back, dark environment from the human sight Can be removed, giving a sense of security to people in a straight path.

[0016]

EXAMPLES Specific examples of the present invention will be described below with reference to FIGS.
This will be described using 1. FIG. 7 shows, as an example, a sketch of a corridor in which the lighting system of the present invention is installed. In the figure, Sa is a single vertical passage, and this straight passage Sa
The straight paths Sb to Sg intersect with each other. Spaces M _{1 and} M ₂ such as a waiting room are in contact with the straight passage Sa.
For convenience of explanation, it is assumed that the person is at the H position and the line of sight is in the direction of the arrow.

Now, the human body detecting section in the straight path Sa detects the person H, and all the lighting fixtures (not shown) belonging to the straight path Sa are turned on. If the straight passages Sb to Sg
And the lighting fixtures belonging to the spaces M _{1 to} M ₂ are not turned on, the illuminance of the shaded portion in the figure is the straight passage Sa.
Since the illuminance is lower than the illuminance of the other non-existing portion N (for example, the dotted line portion in the drawing) in the inside, the person H may feel anxiety for the above reason. For example, regarding the intersections Sa and Sh of the straight passages, the straight passage Sh (the above-mentioned straight passages Sb to Sg and the spaces M ₁ to
The area (representing M ₂ ) is the area of the horizontal line portion in FIG. 8, and the illuminance at this portion is considered to be low. Therefore, in all of the regions Ab to Ag and A _{1 to} A ₂ which are boundaries between the straight passage Sa, the straight passages Sb to Sg intersecting with the straight passage Sa, and the spaces M _{1 to} M ₂ in FIG. The illuminance is substantially equal to or higher than the illuminance of the portion N where the adjacent space does not exist. By doing so, the anxiety of person H can be reduced.

The means will be described with reference to FIG.
It In the figure, the straight passage Sh is the above-described straight passages Sb to Sg and
And space M₁~ M₂It is assumed to be representative of. Human body examination
When the outlet detects a human body in the straight passage Sa, at least
Lighting equipment K₁And K₃If you do not have the desired illuminance
Lighting equipment K₂, K_FourSo that it lights up or dims
A command is issued to each device. Also, FIGS.
Lighting equipment near the intersection of the straight paths Sa and Sh as shown in
Are arranged closer to each other than the non-existing portion N of the adjacent space.
It In FIG. 10, the lighting fixture K₇, K₈, The illuminator in FIG.
Ingredient K₁₃, K₁₄, K _FifteenIs a densely arranged lighting fixture.
As a result, if the desired illuminance is reached, the straight passage S
It is not necessary to light or dimmer the lighting fixtures belonging to h.

The above description is an example, and in short, in order to set the illuminance at the boundary to a desired illuminance, the lighting equipment in the linear passage Sh may be controlled by the information of the human body detecting section. It is not necessary to consider the boundaries between all the straight passages Sb to Sg and the spaces M _{1 to} M ₂ that intersect the straight passage Sa.
Straight paths Sb to Sg and spaces M _{1 to} M ₂ that belong to within 5 to 7 m from a person, a boundary Ab of the straight path Sb closest to the person, a boundary Ab of the straight path Sb closest to the person and the innermost straight line Only the boundary Ag of the passage Sg, the straight paths Sb to Sg relatively close to a person, and the boundaries of the spaces M _{1 to} M ₂ may be considered. The reason for setting as above is that in the case of a corner, a person confirms his / her feet.
This is because there is a viewpoint at 7m. The reason for setting as described above is to reduce anxiety by brightening an area in which a person is likely to turn in advance. The reason for setting as described above is that, as is clear from the above reason and the experimental result of FIG. The reason for setting as described above is that the control of the lighting fixture away from the person is a problem in terms of construction, and therefore, the method of brightening the intermediate portion is selected from the experimental result of FIG.

In the above-described embodiment, the main control path of the luminaire is the main straight path Sa and the straight paths Sb to S intersecting with it.
Although it is limited only to the boundary between g and the spaces M _{1 to} M ₂ , this control range is limited to the straight passages Sb to Sg and the spaces M _{1 to} M _2.
It may be extended to all spaces. By doing so, lighting control becomes easier.

Further, in FIG. 7, the straight passages Sb to Sg are provided.
Also, the illuminance of an area within the field of view of the person H among the spaces M _{1 to} M ₂ may be substantially equal to or higher than the illuminance of the portion N where the adjacent space does not exist. This reduces the anxiety of person H. In addition, since the person H is looking ahead, since his / her eyes are within 20 m, 2
It may be limited to within 0 m. Even with such a limitation, the anxiety of person H is sufficiently reduced.

[0022]

According to the first aspect of the present invention, at least one lighting device having a function of detecting the presence of a person and turning on the lighting fixture in a lighting environment in which another portion adjacent to the straight path exists, In a lighting system in which a plurality of luminaires that can be controlled by a lighting device are arranged, when a person is present in a straight path, a luminaire belonging to the straight path is turned on, and the person's field of view is adjacent to the straight path. When including a part of the space of another location, the illuminance of the space is set to be substantially equal to or higher than the illuminance of a portion not having the adjacent location of the linear passage, It is possible to reduce the anxiety of a person when a person passes by or when there is a person in the lighting environment where the place exists. Further, as in claim 4, by setting the illuminance of all the spaces of the adjoining portions to be substantially equal to or higher than the illuminance of the portion not having the adjoining portions of the linear passage, the control method is simplified, and therefore the installation This has the effect of facilitating construction. Further, in claims 5 to 11, since the range in which the illuminance is increased by the lighting equipment can be limited, there is an effect that an energy saving effect can be obtained.
