DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. 1 is a configuration diagram of a lighting control system according to a first embodiment of the present invention. In the figure, the same or corresponding parts as those of the prior art are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 10 denotes a lighting controller, which is connected to the inverter 4 and the communication means 11, outputs a dimming signal for determining a lighting output to the inverter 4, and controls the lighting output of the lighting fixture 5 from an unlit state to a 100% output state. In addition, it is configured to be able to output its own control state to the transmission line 6 using the communication means 11.

Reference numeral 12 denotes a breaker terminal, which controls the opening and closing of a remote control breaker 13 by its output, and has communication means 14 so that information can be collected via the transmission line 6. Note that the communication unit 11, the communication unit 14, and the breaker terminal 12 indicate a first communication unit, a second communication unit, and a first breaker terminal, respectively.

Next, the operation will be described. First, an operation in the case where the communication means 11 is configured as a contact such as a relay and the communication means 14 is configured as a contact input will be described. Communication means 1
The output of 1 indicates that the relay contact is "closed" when the lighting is on,
When the light is turned off, that is, when the inverter 4 stops oscillating due to the dimming signal from the lighting controller 10 and the lighting output from the lighting fixture 5 becomes 0, it is configured to be “open”.

The breaker terminal 12 outputs an output for controlling the opening of the remote control breaker 13 when the state detected by the communication means 14 is "open", and performs an output for performing the closing control when the state detected by the communication means 14 is "closed". . The communication means 11 of each lighting controller 10 is connected in parallel by the transmission line 6, and the breaker terminal 1
2 communication means 14.

Therefore, when at least one of the lighting controllers 10 is turned on, the communication means 14 detects the contact "closed", whereby the breaker terminal 12 sets the remote control breaker 13 to the "closed" state. And supplies power to each inverter 4. When all the lighting controllers 10 are turned off, the communication means 14 detects the contact “open”, whereby the breaker terminal 12 controls the remote control breaker 13 to the “open” state, and supplies power to each inverter 4. Stop supplying. By this operation, consumption of standby power of the inverter 4 can be eliminated.

As described above, since the information collecting function for cooperation is distributed and provided to the breaker terminal 12, a control system for reducing unnecessary standby power can be configured. A configuration that is not required can be provided.

Embodiment 2 FIG. FIG. 2 is a diagram showing a form of a control system of a lighting control system according to a second embodiment of the present invention. Note that the configuration diagram is the same as that of Embodiment 1, and FIG. 1 is used. In the figure, the transmission line 6 is configured using any one of an object using an electric wire or a communication medium such as wireless or infrared without electric wiring. The communication means 11 and the communication means 14 have address codes for self-identification.

Next, the operation will be described. Communication means 11
The operation when the communication means 14 is configured by serial communication will be described. The breaker terminal 12
The address code of the communication means 11 of the lighting controller 10 to which the inverter 4 which is turned on and off by the remote control breaker 13 which is controlled in advance is stored. The breaker terminal 12 uses the communication means 14 and the address code of the communication means 11 is stored. By designating the code, the communication means 11 is called up sequentially, and the control state of the lighting fixture 5 is collected.

When all of the collected control states are off, the breaker terminal 12 controls the remote breaker 13 to "open" and stops supplying power to each inverter 4. If at least one of the collected lighting states indicates a lighting state, control is performed to keep the remote control breaker 13 in the “closed” state.

As described above, according to this configuration, regarding turning on and off of the power supply, the breaker terminal 12 independently controls each lighting fixture 5.
Since the illumination state is collected and the power supply is controlled, a system configuration that does not require a dedicated terminal for communication control becomes possible.

Embodiment 3 FIG. FIG. 3 is a diagram showing a form of a control system of a lighting control system according to Embodiment 3 of the present invention. Note that the configuration diagram is the same as that of Embodiment 1, and FIG. 1 is used. In the figure, a transmission line 6 is configured so that a transmission signal is transmitted in a ring shape so that a transmission signal returns to the breaker terminal 12 via each lighting controller 10 sequentially from the breaker terminal 12 as a transmission source.

Next, the operation will be described. First, a transmission signal that travels between each terminal includes each lighting controller 10.
A common field indicating an illumination output state according to the dimming output state is prepared. Each lighting controller 10 operates so as not to write if it is turned off according to its own lighting state, and to write 1 to the common field if it is turned on.

Therefore, the breaker terminal 12 is connected to the communication means 14
To output a transmission signal having a common field of 0 to the first lighting controller 10a. First lighting controller 1
0a receives this transmission signal and starts the common field changing process. In this case, since the illumination state of the first illumination controller 10a is turned off (off), the transmission signal is output to the second illumination controller 10b without changing the common field. Since the second lighting controller 10b that has received the transmission signal in the same manner as described above is in the lighting state (ON), it writes "1" in the common field and transmits the transmission signal to the third lighting controller 10c.

Hereinafter, all the lighting controllers 1 are operated in the same procedure.
The common field is changed for 0, and the transmission signal finally returns to the breaker terminal 12. The breaker terminal 12 reads the common field of the returned transmission signal, and if "1", keeps the breaker 13 in the "closed" state,
If it is “0”, it is determined that all the lighting controllers 10 are turned off, the remote controller breaker 13 is opened, and the supply of power to the inverter 4 is stopped.

As described above, according to the present configuration, the breaker terminal 12 can realize the collection of the lighting state of each lighting fixture by reading the common field. In addition, since the range of collection is determined by the connection method of the transmission line 6, a system configuration that does not require a communication setting operation and does not require a dedicated terminal for communication control becomes possible.

Embodiment 4 FIG. FIG. 4 is a configuration diagram of a lighting control system according to a fourth embodiment of the present invention. In the drawing, the same or corresponding portions as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 15 denotes a second breaker terminal, which controls opening and closing of the breaker 13 based on input information from the outside. In this configuration, the power of the lighting controller 10 is controlled to be opened and closed by the breaker terminal 15. Note that the breaker terminal 15 indicates a second breaker terminal.

Next, the operation will be described. When all the luminaires 5 connected to the same power line are turned off, the first breaker terminal 12 operates to “open” the breaker 13 to stop the power supply to the inverter 4 as in the above embodiment. It operates to eliminate standby power when the signal is turned off. In the present embodiment, when power is not needed, the power of the lighting controller 10 itself is turned off to further reduce standby power.

The external input to the breaker terminal 15 is linked with a signal for entering or leaving a room, a floor, or a building. For example, in the case of a final exit such as locking of a key, the power supply of the lighting controller 10 is controlled to “open” to turn off the breaker 13, and in the case of a signal indicating entry such as unlocking of a key, the breaker 13 is “closed”. The breaker terminal 15 is configured to control and supply power to the lighting controller 10.

When locked in the above configuration, the external signal is in a locked state, the second breaker terminal 15 operates the "breaker" to "open", cuts off the power supply path to the lighting controller 10, and loses standby power. I do.

Embodiment 5 FIG. FIG. 5 is a configuration diagram of an illumination control system according to a fifth embodiment of the present invention, FIG. 6 is a diagram illustrating the operation of the illumination control system, and FIG. 7 is a configuration diagram of an illumination near roller of the illumination control system. In the drawing, the same or corresponding portions as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.

Each of the lighting controllers 10 has a human sensor 101, and has a standby mode as an operation mode. In the standby mode, only the input from the communication means and the motion sensor are operating, and when the standby mode is released from the communication means and the built-in motion sensor detects the presence of the room, all the control parts are energized and the normal operation is performed. It is in the operating state.

Next, the operation will be described. The breaker terminal 12 monitors the lighting state using the communication means 14 and the communication means 11 for each lighting controller 10. When the responses from all the lighting controllers 10 are off, that is, turned off, the breaker terminal 12 instructs each lighting controller 10 to operate in the standby mode using the communication means 14. Lighting controller 1 receiving the instruction of the standby mode
In the case of 0, the output of the dimming signal to the inverter 4 is stopped, and the control power excluding the motion sensor and the communication means is turned off to enter the standby mode. In this state, power is not supplied to the inverter 4 and the standby power is reduced.

Next, when the human sensor 101 built in the lighting controller 10 detects the presence of the room, the lighting controller 10 which has detected the presence of the room uses the communication means 11 to notify the breaker terminal 12 of the return of the standby mode ("return" in the figure). Send to Upon receiving the return, the breaker terminal 12 transmits a standby mode release to all the lighting controllers 10. When receiving the standby mode release, the lighting controller 10 starts energizing the entire control circuit and returns to the normal operation state. When the lighting controller 10 does not need to operate in the absence of a person, supply of power is stopped to reduce standby power.

Although the communication means is not specified in the fifth embodiment, information collection by the human sensor is performed by using any of the serial transmission means shown in the second and third embodiments, and a similar procedure is performed. Can be collected at That is, it can be realized by executing information collection and command notification by the breaker terminal 12. In ring communication, a common field is provided with two bits, and one bit is used for information collection by the human sensor. This can be realized by allocating bits to the instruction / release of the standby mode.

[0040]

Since the lighting control system of the present invention is configured as described above, the breaker is operated in conjunction with the lighting output state of the lighting fixture which is autonomously driving and operating.
Control for reducing wasteful standby power consumed by the inverter can be achieved only by connecting the transmission lines in parallel. At this time, the above control can be realized with a configuration that does not require a terminal such as a master station that exists only for control.

As for the power on / off, the breaker terminal independently collects the lighting state of each lighting fixture of the lighting system independently operated and controls the power supply, so that standby power can be reduced. In both cases, a dedicated terminal for communication control is not required, and an inexpensive system can be constructed.

Furthermore, since a common field is provided in the transmission signals of the lighting controller and the breaker terminal to write and control information according to the lighting state, the breaker terminal can collect the lighting state of each lighting fixture only by reading the common field. realizable. Further, since the range of collection is determined by the transmission line connection method, a system configuration that does not require a communication setting operation and does not require a dedicated terminal for communication control is possible.

Further, since the power supply of the lighting controller is also cut off when it is not necessary, such as when the player leaves the final stage,
An illumination control system capable of reducing standby power can be obtained.

A standby mode is provided in the lighting controller to control the standby mode when all lights are turned off according to an instruction from the breaker terminal. Since the mode is controlled to be released, the power consumption of the lighting controller can be reduced when the operation of the lighting controller is unnecessary, such as when the scene is absent or turned off, and an energy-saving lighting system can be obtained as a whole.
