The lighting control device 11 includes a processor 11a, a main storage device 11b, an auxiliary storage device 11c, a communication circuit 11d, a wireless circuit 11e, and a bus 11f.
In the lighting control device 11, a computer is configured by connecting the processor 11a, the main storage device 11b, and the auxiliary storage device 11c through a bus 11f.

The auxiliary storage device 11c stores an application program.

  The application program stored in the main storage device 11b or the auxiliary storage device 11c includes a control program describing a procedure of control processing described later. This control program is stored in the main storage device 11b or the auxiliary storage device 11c when the lighting control device 11 is transferred to the user. However, the hardware of the lighting control device 11 may be transferred to the user in a state where the control program is not stored in the main storage device 11b or the auxiliary storage device 11c. Then, the control program may be written to the main storage device 11b or the auxiliary storage device 11c in accordance with an instruction from the user or the like. In this case, the control program may be transferred to a user by being recorded on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, or a semiconductor memory, or downloaded via a network.

The communication circuit 11d sends control data to each of the lighting fixtures 1 to 5 to the communication network 12 under the instruction from the processor 11a.

  In using this lighting system, the lighting state table and the gesture table are stored in the main storage device 11b or the auxiliary storage device 11c. The contents of the lighting state table and the gesture table may be arbitrary, and the contents may be set by a user, for example.

FIG. 3 is a diagram showing an example of the contents of the lighting state table T1.
The lighting state table T1 indicates combinations of lighting states of the lighting fixtures 1 to 5. For example, in the combination with the name “first state”, the lighting states of the first to fourth lighting fixtures are all “lit (large)”, and the lighting state of the fifth lighting fixture is “off”. is there. In the combination with the name “second state”, the lighting states of the first and second lighting fixtures are both “lit (large)”, and the lighting states of the third and fourth lighting fixtures are both “ “OFF” and the lighting state of the fifth lighting fixture is “ON (low)”. In the combination with the name “fifth state”, the lighting states of the first to fourth lighting fixtures are all “lighting (small)”, and the lighting state of the fifth lighting fixture is “lighting (high)”. It is.
Lighting fixtures whose lighting state is “off” are not turned on. All lighting fixtures that are lit (large) and lit (small) are turned on, but when lit (large), they emit light compared to lit (small) Increase strength. All lighting fixtures whose lighting status is “lit (high)” and “lit (low)” are lit, but when “lit (high)”, they are colored compared to when “lit (low)” Increase the temperature.
Here, the first to fifth lighting fixtures correspond to the lighting fixtures 1 to 5, respectively.

FIG. 4 is a diagram showing an example of the contents of the gesture table T2.
The gesture table T2 indicates which lighting state is applied to the gesture of the operator OP. For example, for a gesture defined as “first gesture”, the second state is applied when the second sensor is OFF, and the fourth state is applied when the second sensor is ON. Represents.
Here, the second sensor corresponds to the sensor unit 7. The case where the second sensor is ON indicates a state where the sensor unit 7 detects a human being, and the case where the second sensor is OFF indicates a state where the sensor unit 7 does not detect a human being.

Next, the operation of the illumination system configured as described above will be described.
When the start of the control process is instructed, the processor 11a starts the control process based on the control program stored in the main storage device 11b or the auxiliary storage device 11c. The start instruction may be given by an operation with an input device (not shown) such as a keyboard or a mouse connected to the lighting control device 11 or attached to the wall surface of the room R. It may be performed by operating a switch.

FIG. 5 is a flowchart of control processing by the processor 11a.
In step Sa1, the processor 11a sets the first state as the lighting state. Specifically, the processor 11a refers to the lighting state table T1, checks each lighting state of the lighting fixtures 1 to 5, and sends control data for instructing the lighting state to each of the lighting fixtures 1 to 5. To send. That is, the processor 11a controls the communication circuit 11d so as to send control data representing “lighting (large)” to each of the lighting fixtures 1 to 4 to the communication network 12. In addition, the processor 11 a controls the communication circuit 11 d so as to send control data indicating “light off” to the communication network 12 addressed to the lighting fixture 5.

When the control data addressed to the luminaire 1 is transmitted to the luminaire 1 via the communication network 12, the control circuit 1d receives this control data and gives it to the control circuit 1c. The control circuit 1c controls the lighting circuit 1b according to the control data so that the light source unit 1a emits light with a predetermined light emission intensity in association with “lighting (large)”. Note that the light emission intensity for each of “lighting (large)” and “lighting (small)” is arbitrarily determined by, for example, the designer or user of the lighting fixture 1, and the set value is stored in the memory in the control circuit 1c. May be stored. Alternatively, these light emission intensities may be arbitrarily determined by the user of the illumination control device 11 and the set values may be stored in the main storage device 11b or the auxiliary storage device 11c. In the latter case, the processor 11a includes the set value of the light emission intensity in the control data.
Also in the lighting fixtures 2-4, the same operation | movement as the lighting fixture 1 is performed. In the lighting fixture 5, the control circuit controls the lighting circuit so that the light source unit is turned off.
Thus, in the initial stage, each of the lighting fixtures 1 to 4 emits light with a large light emission intensity, and many areas of the floor F1 of the room R are illuminated brightly. At this time, the lighting fixture 5 is not illuminated.

In step Sa2, the processor 11a waits for one of the sensor units 6 and 7 to detect a human.
Now, when the audience AU exists in the front area of the floor F1, the sensor unit 6 detects a person. When the audience AU is present in the rear area of the floor F1, the sensor unit 7 detects a person. Then, the sensor units 6 and 7 send detection start data to the illumination control device 11 to the communication network 12 in response to the fact that humans can be detected in this way. When the detection start data is transmitted to the lighting control device 11 via the communication network 12, the detection start data is received by the communication circuit 11d. Then, the processor 11a determines Yes in step Sa2, and proceeds to step Sa3.
The processor 11a may monitor the amount of human activity existing on the floor F1 based on the moving image data transmitted by the photographing unit 9, and may perform the determination in step Sa2 in consideration of this information. For example, the processor 11a may detect a still person as a person whose activity amount is equal to or less than a specified value, and may determine Yes in step Sa2 when the number of still persons is equal to or more than a specified number.

In step Sa3, the processor 11a confirms whether or not a gesture of the operator OP that is predetermined for the lighting operation is detected. If the processor 11a determines No because the corresponding gesture has not been detected as described later, the processor 11a proceeds to step Sa4.
In step Sa4, the processor 11a confirms whether one of the sensor units 6 and 7 is detecting a human. If the processor 11a determines Yes because the person is still detected, the processor 11a returns to step Sa3.
Thus, in step Sa3 and step Sa4, the processor 11a waits for a gesture to be detected or for no human being to be detected.

  Now, the processor 11a performs a detection process as a process different from the control process shown in FIG. The detection process detects the body pose of the operator OP based on the moving image data obtained by the photographing unit 8 and the motion data transmitted from the wearable terminal 10 and received by the wireless circuit 11e, and a gesture is detected as a change in the body pose. This is a process for detecting. As this detection processing, for example, an existing technique can be used, and thus detailed description thereof is omitted. In the detection process, both moving image data and motion data may be used, or only one of them may be used. If only one of them is used, the photographing unit 8 or the wearable terminal 10 can be omitted from the lighting system. Thus, when the processor 11a executes the control process based on the control program, the computer having the processor 11a as a central part functions as a detecting means for detecting the body pose of the operator.

When the processor 11a detects a gesture by the above detection process in the standby state of steps Sa3 and Sa4 of the control process shown in FIG. 5, the processor 11a determines Yes in step Sa3 and proceeds to step Sa5. .
In step Sa5, the processor 11a determines the lighting state to be applied. That is, the processor 11a determines the lighting state associated with the gesture detected by the detection process in the gesture table T2. In the gesture table T2 shown in FIG. 4, two lighting states corresponding to whether the second sensor is ON / OFF are associated with one gesture. Also refer to the detection state. The sensor unit 7 transmits detection start data or detection end data when the detection state changes. For this reason, the processor 11a makes it possible to confirm the detection state in the sensor unit 7 by setting / resetting the flag in response to reception of detection start data and detection end data, for example.
Specifically, the processor 11a determines that the lighting state to be applied is the second state when the gesture defined as the “first gesture” is detected and the sensor unit 7 does not detect a person. . In addition, when the gesture defined as the “first gesture” is detected and the sensor unit 7 detects a person, the processor 11a determines that the lighting state to be applied is the fourth state.

  When the processor 11a is in the standby state of step Sa3 and step Sa4 and enters a state where no human being is detected by any of the sensor units 6 and 7, the processor 11a determines No in step Sa4 and returns to step Sa1. That is, unless at least one of the sensor units 6 and 7 is detecting a human, the processor 11a does not execute Step Sa5. Therefore, the case where the sensor unit 7 does not detect a person in step Sa5 is a situation where a person exists only in the front area of the floor F1. The case where the sensor unit 7 detects a person in step Sa5 is a situation where a person exists in at least the rear area of the floor F1.

  By the way, the processor 11a may monitor the number of humans present on the floor F1 based on the moving image data transmitted by the photographing unit 9, and may perform the determination in step Sa5 in consideration of this information. For example, the processor 11a may change the light emission intensity or the color temperature of the lighting fixture 5 depending on whether or not the number of persons is equal to or more than a specified number. In this way, it is possible to vary the operation content according to the gesture according to not only the presence / absence of a person existing on the floor F1, but also the presence state of the person.

In step Sa6, the processor 11a sets the lighting state determined in step Sa5. The processor 11a performs the processing in step Sa6 in the same manner as in step Sa1. However, the processor 11a sets the lighting state represented by each control data to the state described in the lighting state table T1 with respect to the lighting state determined in step Sa5.
In other words, the processor 11a specifically turns on the luminaires 1 and 2 with a large light emission intensity, turns off the luminaires 3 and 4 and determines the luminaire 5 to have a low color temperature when it is determined in step Sa5 that it is in the second state. Turn on with. If the processor 11a determines that the state is the third state in step Sa5, the lighting fixtures 1 and 2 are turned on with a small emission intensity, the lighting fixtures 3 and 4 are turned off, and the lighting fixture 5 is turned on at a high color temperature. When the processor 11a determines that the state is the fourth state in step Sa5, the lighting fixtures 1 to 4 are turned on with a large emission intensity, and the lighting fixture 5 is turned on with a low color temperature. When the processor 11a determines that the state is the fifth state in step Sa5, the lighting fixtures 1 to 4 are turned on with a small emission intensity, and the lighting fixture 5 is turned on with a high color temperature.

As described above, when the processor 11a executes the control process based on the control program, the computer having the processor 11a as the central part functions as a control unit. The function as the control means is a function to change at least one of the lighting equipment to be controlled and the lighting state after the change depending on whether or not a human being existing within a predetermined range is detected. is there.
Thereafter, the processor 11a returns to the standby state in steps Sa3 and Sa4.

  According to the lighting system as described above, in a situation where no human is detected in any of the sensor units 6 and 7, that is, in a situation where the audience AU does not exist on the floor F1, the lighting fixtures 1 to 5 corresponding to the gestures The lighting state is not changed. That is, when there is no audience AU, the lighting operation by the gesture is invalidated. This is equivalent to changing the lighting equipment to be operated by the gesture depending on whether or not a human being is detected.

Further, according to the lighting system, in a situation where a human is detected in at least one of the sensor units 6 and 7, the lighting state set according to the same gesture indicates whether the sensor unit 7 detects a human. It depends on whether or not.
For example, when the first gesture is detected when the lighting state is in the first state, the lighting state of the lighting fixtures 3 and 4 changes if the sensor unit 7 does not detect a person, but the person is detected. If it does, the lighting state of the lighting fixtures 3 and 4 will not change. That is, depending on whether or not the sensor unit 7 detects a human being existing within a predetermined range, the lighting fixture to be controlled corresponding to the gesture changes.

  For example, when the second gesture is detected when the lighting state is the fourth state, the lighting state of the lighting fixtures 3 and 4 is changed from “lit (large)” to “ If the person is detected, the lighting state of the lighting fixtures 3 and 4 changes from “lit (large)” to “lit (small)”. That is, the lighting state after being changed according to the gesture changes depending on whether or not the sensor unit 7 detects a human being existing within a predetermined range.

  Thus, the above-described control by the illumination control device 11 makes it possible to control various illumination states with a small number of gestures.

This embodiment can be variously modified as follows.
The processor 11a may determine the lighting state to be applied based on the body pose itself, not based on the gesture that is a change in the body pose of the operator OP.
The lighting state set by the illumination control device 11 is, for example, changing the light emission intensity or the color temperature in three or more steps, or changing the light emission intensity or the color temperature by a certain amount with respect to the light emission intensity or the color temperature before the change. Thus, it can be changed as appropriate.
