Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a lighting system.

[0002]

2. Description of the Related Art A lighting system for linking surrounding lighting fixtures.
As a system, there are various technologies. For example, figure
11, each lighting having a unique address... As shown in FIG.
Utensil 1 ₁The lighting fixture 1 in which the control master unit 2 works in conjunction with.
There is a lighting system that specifies and controls each unit.

In the case of this conventional example, the luminaires 1 ₁ ... Are provided with a human sensor (not shown) for detecting a human body.
The detection information of the human sensor is sent to the parent device 2 via the signal line 3, and the parent device 2 determines the lighting equipment to be controlled in conjunction based on the detection information, and specifies and controls the lighting equipment one by one. Is transmitted to each of the lighting fixtures 1 ₁ ... Via the signal line 3.

[0004] That luminaire as shown in FIG. 11 (a) 1 ₇
11 detects the human body M, the lighting fixture ₁₇ transmits the detection information to the parent device 2 via the signal line 3 (FIG. 11).
(B) stage). Master set 2 luminaires to be controlled based on the detection information, in this case determines the luminaire 1 ₁ to 1 _3, 1 _6, 1 _{8-1 11} adjacent to the luminaire 1 _7, this decision luminaire ₁ 1 to 1 ₃ corresponding based, 1 _6,
For example, a control signal designating addresses of ₁₈ to ₁₁ for instructing lighting is transmitted via the signal line 3 (step (c) in FIG. 11). Luminaire ₁ 1 to 1 ₃ to thereby corresponding,
₁₆ , ₁₈ to ₁₁ receive the control signal and turn on their own lighting loads as shown in FIG.

In this conventional lighting system, fine control in groups can be performed, for example, control as shown in FIG. That motion sensor of FIG. 12 in the lighting fixture 1 ₁₂ and 1 ₃ have detected the respective human body M, the parent device 2 lighting loads only those luminaires 1 ₁₂ and 1 ₃ at 100%, based on the detection information And lighting equipment 1 around it
_2, 1 ₄ to 1 _7, 1 _11, and is lit dimming in 1 ₁₀ at a predetermined level. In this way, individual lighting fixtures can be easily controlled by the judgment and instruction of the parent device 2.

However, in the conventional system, when the entire system is viewed, it is natural that a plurality of groups exist in the system. Therefore, the parent device needs to separately control a large number of groups at the same time, and also needs to recognize the positional relationship between the respective luminaire addresses. That what the addresses of around luminaire luminaire 1 _7, and as that what addresses around the luminaire luminaire 1 _8, should be recognized for all luminaire 1 ₁ ... relationship Therefore, the burden on the base unit 2 is large, and a high-speed, high-performance base unit 2 is required.
It was inevitably expensive. Also, whatever goes through the master unit 2, if the master unit 2 breaks down,
In the worst case, there is a risk that the entire system will not operate. That is, the form of the system is too dependent on the parent device 2.

On the other hand, a distributed lighting system which does not depend on a parent device has been conventionally provided. This distributed lighting system does not have a parent device for centralized management as shown in FIG. 13, and each lighting device 1 ₁ ... Since the lighting of the load is controlled, it is not necessary to set an address for each of the lighting devices 1 ₁ ... In terms of the interlocking lighting, and only the lighting devices around the own device need to be recognized in advance. There is a feature that becomes. To briefly explain the operation,
First, when the human body sensor of the luminaire 1 ₇ as shown in FIG. 13 (a) detects a human body M, the Toto luminaire 1 ₇ to light the lighting load, it sends its own status information via the signal line 3 I do. Other luminaires 1 ₁ to 1 _6, 1 ₈ ... the state information transmitted via a signal line 3 to determine whether they need to self. In this case, the lighting fixture 1 adjacent to the lighting fixture ₁₇
Since ₁ to 1 _3, 1 _6, 1 _{8-1 11} knows that it is adjacent the instrument with respect to the luminaire 1 ₇ takes the status information, the self-lighting load according to the state information, for example Turn on.

Although such a distributed processing type lighting system is characterized in that it does not depend on the parent device, each lighting fixture 11 ₁
However, there is a problem in that a very high-performance device is required, which results in an increase in price. Furthermore, it is very difficult to perform controlled interlocking control (pattern control) within a group, that is, to judge the self-lighting state from the state of all the components in each group.
To do this, each lighting fixture 1 ₁ … needs to have a function like a master unit in a centralized control type system,
In this case, it becomes very expensive.

[0009] This point will be described with reference to FIG. 14, their in each luminaire for the case where the person detecting sensor of the luminaire 1 ₁₂ and 1 ₃ is detecting the respective human body M, the illumination device 1 _12, 1 ₃ To determine where they are located, how are the other lighting fixtures, and at what level it is better to turn on their own lighting loads?
Control is required for each individual luminaire, and also requires the exchange of fairly complex information between each luminaire. Therefore, there is a problem that high functionality and high price are unavoidable.

In addition to the above-described lighting system configuration, there is also a lighting system in which grouping is performed in advance by wiring. In this system, a group of lighting fixtures is determined at the time of construction, and control is performed only within the group.
As shown in (a), one control unit 4a.
The lighting devices 1 are connected by wiring to form a group A. For example, when a human sensor provided in the control unit 4a detects a human body as shown in the figure, the control unit 4a
Illuminating the lighting loads of the luminaires 1...

However, in this system, the number of control units (luminaires in a group) is limited, so that the system is inflexible. Further, as shown in FIG. In addition, a change to make the same group E that has been changed requires a change in wiring, that is, rebuilding, and there is a problem that the change is difficult.

Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) As shown in FIG. 1, a lighting fixture 1 used in this embodiment is transmitted from an illuminance sensor 10, a human sensor 11, and a remote controller 19 using a light (infrared light) signal as a signal medium. A remote control signal receiving unit 15 for receiving the remote control signal, a storage unit 16, a communication unit 17 for transmitting detection information of each of the sensors 10 and 11 to another lighting fixture, and a control unit 13.
And the lighting load 12 controlled by the control unit 13.

The feature of the present embodiment is that a leader device is arbitrarily determined in a group that performs an interlocking operation, and another lighting device in the group (hereinafter referred to as a follower device).
Is to control the In other words, the leader device substitutes the function of the parent device in the centralized management type system and controls the lighting state of the group based on information from each follower device, but the leader device is fixed. However, even in the same group, the equipment to be the leader differs depending on the conditions. That is, the control functions do not always concentrate. Also, the leader device only needs to control the group to which it belongs, and the burden on the parent device (leader) does not increase as in the centralized management type system.

On the other hand, the follower device does not change the lighting state by its own judgment when the leader device to be followed is determined. When the own sensor information (detection information of the human sensor 11 and information of the detected illuminance of the illuminance sensor) is transmitted to the leader device, the leader device determines the optimal lighting state of each follower device by looking at the entire group. In other words, the follower device becomes a kind of sensor terminal. Therefore, it is possible to perform the groove interlocking operation without saying that each lighting fixture as in the distributed system becomes too sophisticated.

Next, the operation of this embodiment will be described with reference to FIGS. First, the person detecting sensor 11 of the luminaire 1 ₇ in FIGS. 2 (a) detects a human body M, the control unit 13 of the lighting apparatus 1 ₇ has detected the human body M via the communication unit 17 together to turn on the illumination load 12 The detection information is transmitted via the signal line 18 (FIG. 2B). At the same time, the control unit 13 recognizes that the luminaire 1 ₁ itself belongs is the leader device.

At the same time, the control unit 13 of the reader device ₁₇ dims the lighting load 12 at 80%. The signal line 18 of each follower device 1 ₂ which has received a signal via the communication unit 17 of the respective through, 1 _{11, 1} 1, 1 _6, 1 _10, 1
₈ and _19, the control unit 13 controls the lighting load 12 according to the instruction.
Is controlled (FIG. 3D). In this way, a non-leading lighting fixture (follower fixture) temporarily regards the leader fixture as a parent device and leaves itself under control.

In the present embodiment configured as described above, the centralized management type system cannot operate at the time of an abnormality (at the time of failure) due to the large dependence on the parent device, which is a problem with the centralized management type system. , High cost due to the increase in the burden on the parent device, and the difficulty of group interlocking operation (pattern control) in a distributed and distributed system,
In addition, there is an effect that all points such as high price can be solved.

In the present embodiment, the luminaire that first detects the human body M is the leader, but is not particularly limited. The use sensor is not limited to the human sensor and the illuminance sensor, and may be any means capable of instructing lighting or detecting the lighting state of an adjacent lighting device. Further, in the present embodiment, the leader device determines the lighting pattern based on the detection information of the human sensor 11 of the follower device. However, the present invention is not limited to this. It may be a pattern that has been used.

(Embodiment 2) This embodiment constitutes a lighting system that allows overlapping of group settings. In the lighting fixture 1 used in this embodiment, as shown in FIG. It comprises a control unit 13 for controlling the illumination load 14 with appropriate information, a storage unit 16 for storing information, and a communication unit 17 for transmitting and receiving signals via a signal line 18.

Next, the operation of this embodiment will be described with reference to FIG. In this embodiment, first, Yes divided luminaire 1 ₁ ... into a plurality of groups, there when the illumination load 12 is turned in the luminaire, the communication unit 1 under the control of the control unit 13
Lighting information is transmitted from 7 via a signal line 18. Upon receiving the lighting information via the communication unit 17, the control unit 13 of the lighting fixture belonging to the same group stores the lighting information in the storage unit 16 and operates in conjunction with the lighting load 12 to output the same output level as that of the lighting load 12 of the lighting fixture that has been turned on first. To light up.

On the other hand, when receiving the lighting information via the communication unit 17, the control unit 13 of the lighting fixture belonging to the group which is in an interlocking relationship around this group stores the lighting information in the storage unit 16 and interlocks with the output level at a predetermined output level. , Lighting load 1
2 is dimmed and lit. When one of the groups is turned off, the light-off information is transmitted from the lighting fixtures belonging to the group via the signal line 18, and the light-off information is transmitted.
The lighting equipment of the other group in the interlocking relationship that has received the light-off information also turns off the lighting load 12. At this time, the storage unit 16 of each lighting fixture rewrites the lighting information stored under the control of the control unit 13 to lighting-out information.

[0035] In those make such a basic operation, the luminaire 1 _{2-1 4} belonging to the group α as shown in FIG. _{5 (a), 1 7 ~1} 9, 1 12 ~1 14 of, When the luminaires 1 ₁₃ and 1 ₁₄ also belong to the group β that is linked to the group α, the following control operation is performed.
That consider the lighting load 12 each in the luminaire 1 ₁₅ to 1 ₁₈ only belong to the group β in a state that is lit at 100% power, the luminaire 1 ₂ - group α which are linked to this group β 1 _4, 1 _{7-1 9,} 1 _{12-1 14} in the group α luminaire 1 _{2-1 4} only belong, 1 _7-1
In steps ₉ and ₁₂ , the respective lighting loads 12 are dimmed and turned on at an output level (for example, 50%) set in advance in accordance with the interlocking control.

On the other hand, the lighting equipment 1 belonging to both groups α and β
_{In 13} and 1 ₁₄ , each lighting load 12 is set to 50% output and 10%.
The output level between 0% output is selected, and the illumination load 12 is turned on. (FIG. 5 (b)). In this case, 50% output and 1
The light is lit at 75% output by taking the average with the 00% output. That is, if the output of the lighting load of the overlapping lighting fixtures is combined with the output of either one of the groups, the boundary between the groups becomes clear and the image is uncomfortable to human eyes. The light output of the lighting load 12 of the lighting equipment overlapping the above is set to an averaged level.

The same applies to the case where three different light outputs overlap. As described above, the luminaires 1 ₁₃ and 1 ₁₄ belonging to the two groups α and β are intermediate between the light outputs of the illuminating loads 12 of the luminaires respectively belonging to the two groups α and β when both groups are interlocked. When the lighting load 12 is turned on with the light output of one of the groups, and one of the groups is turned off, the light output of the lighting load of the other group of lighting fixtures follows the light output of the lighting load (FIG. 5).
(C)).

In the present embodiment, even when there is a lighting device that overlaps with a groove having an extremely different output, the lighting can be controlled comfortably without giving a sense of discomfort or discomfort to a person. The intermediate light output described above is not limited to the average value. (Embodiment 3) This embodiment constitutes a lighting system that detects desk surface illuminance and automatically performs output correction.
The configuration of the load control unit 1 according to the second embodiment is as shown in FIG.
4 is obtained by adding the illuminance sensor 10, the present embodiment system using such lighting apparatus 1 and the luminaire 1 ₁ for illuminating the vicinity of the window W side of the indoor 7, from the window be used in the case that the interlocking the luminaire 1 ₂ for illuminating the remote location.

[0039] That desk top surface of a desk DS in the lower luminaire 1 ₁ on the window W side is very bright subjected to any external light such as sunlight, in the lighting fixture 1 ₂ downwardly away from the window W The upper surface of DS is dark because there is little external light. Each such luminaire 1 ₁ corresponds to the case, 1 ₂ of the illumination load 12 of the lighting fixture each so that the light output at the same brightness with the upper surface of Ryotsukue DS 1 _1, 1 ₂ of the illumination load 12 There is a system for individually controlling the light output of the
Low level La becomes the light output of the luminaire 1 _1, as shown in, the luminaire 1 ₂ optical outputs becomes a high level Lb, the output difference X between both light output seen from the larger becomes too human eye In such a case, there is a problem of giving a feeling of strangeness.

In view of this point, the illuminator according to the present embodiment
Tool 1₁, 1_TwoIs the upper surface of the desk DS detected by the illuminance sensor 10

(Embodiment 4) In this embodiment, as shown in FIG. 9, a control unit 15 for controlling the illumination load 12 based on information given, a storage unit 16 for storing information, And a remote control signal receiving unit 15 that receives a remote control signal similar to the above. The correction is made possible.

Next, the operation of this embodiment will be described. First the illumination system of this embodiment is assumed to be composed of the luminaire 1 _1, 1 _2, which is at least two adjacently arranged, as shown in FIG. 10. Now, in FIG.
_1, 1 is ₂ illumination load 12 is controlled by the control unit 13 so as to both be 100% light output, in spite of the same condition, and variation of the circuit element, lighting load 12
It is assumed that the light output is different to human eyes due to the variation of the illumination load 12 and the new and old illumination load 12.

[0043] Therefore, the remote controller 19, either of the luminaire, for example, transmits the correction coefficient data in 1 ₁ as shown in FIG. 10 (b), received by the remote control signal receiving unit 15 in the lighting fixture 1 ₁ The data of the corrected coefficient (for example, 0.8) is stored in the storage unit 16 under the control of the control unit 13.
To store as information. Thereafter luminaire 1 ₁ of the control unit 1
Numeral 3 controls dimming so that a set output value or a value obtained by multiplying an output value according to a dimming instruction from the remote controller 19 by a correction coefficient becomes a light output of the illumination load 12. That is, FIG.
(C) the light output of the luminaire 1 ₂ illumination load 12 is 10
Lighting load 12 of the lighting apparatus 1 ₁ for being controlled to be 0% are controlled dimming at 100 × 0.8 (%),
It is set to the same state and the light output of the lighting load 12 of the luminaire 1 _2.

[0044] However, still co - state (if not the same light output] (FIG. 10 (d)), compared newly luminaire 1 ₁ the correction coefficient data by using a remote control unit 19 the correction coefficient data (FIG. 10 (e)).
_{In 1} , the data of the correction coefficient (for example, 0.8) received by the remote control signal receiving unit 15 is stored as information in the storage unit 16 under the control of the control unit 13, and
Calculates the light output value again by multiplying the light output value obtained by multiplying the previous correction coefficient by the second correction coefficient (for example, 0.8), and dims and lights the illumination load 12 based on the light output value. .
That is, the lighting load 12 is 100 × 0.8 × 0.8 ≒ 60%
(FIG. 10 (f)).

Even in this case, if the same state is not achieved, the above operation is repeated until the same state is reached. Once the optimum light output state is reached, the correction coefficient at that time is stored in the storage unit 16 and there is no need to reset it. By doing so, it is possible to accurately correct output variation due to lamp replacement or the like while visually confirming it according to human senses. In the above embodiment, the output correction coefficient is given by the remote controller 19, but if the system has a signal line, the output correction coefficient may be given via the signal line.
There is a similar effect.

In this case, the correction coefficient is set for each lighting fixture, but may be given in units of a plurality of fixtures (units of groove).

[0047]

With the above construction, the inventions according to the first to fourth aspects of the present invention do not require a parent device or address for centralized management, and can be used to determine the state of surrounding lighting equipment and external control factors. There is an effect that the information of the detection means can be easily recognized, and fine control can be performed for each control unit.

Further, according to the fifth to tenth aspects of the present invention, there is an effect that the output difference between the luminaires can be reduced, and control can be performed without causing discomfort to human eyes.
