Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting control device that controls a lighting load of a large number of lights by operating an operation unit such as a wall switch.

[0002]

[Prior art]

 In recent years, in lighting fields such as houses and offices, in order to improve various brightness and various lighting effects (for example, atmosphere production) depending on the application, installation of multiple lighting fixtures and various light sources Various control operations are performed by combining and controlling (for example, combining control of a fluorescent lamp and an incandescent lamp), and by combining the same or different light sources in one fixture.

FIG. 4 is an electric circuit diagram showing an example of a conventional lighting control device. An operation section A having an operation switch, and a control signal for blinking, dimming, etc., based on an instruction from the operation section A, is provided. The control signal lines a, b, c, d from the master unit X, which is composed of the output control unit B, to all the lighting loads L ₁ , L ₂ , L ₃ are wired to control the loads. In the figure, E is a power supply and m is a power supply line. In this way, the lighting loads L ₁ , L ₂ and L ₃ are connected to the same control signal lines a, b, c and d so that the blinking or dimming level becomes the same.

[0004]

[Problems to be solved by the device]

 However, for example, in the case of residential lighting, when changing the dimming level of the luminaire with a chandelier in the center of the room and downlights and brackets around the chandelier, for example, the dimming level gradually increases from the window to the back in the office. When performing a more precise control operation, such as when raising the number, the number of control signal lines increases correspondingly, and the control circuit becomes complicated. Furthermore, in places such as conference rooms and presentation rooms where lighting fixtures are installed over a wide area, it is necessary to install operation parts at multiple locations, but it is necessary to wire the control signal lines to all base units. In this case as well, the wiring path becomes long and the wiring becomes complicated.

The present invention solves such a problem. According to the combination of lighting devices having various light sources, the control signal line can be easily wired, and the control signal line can be arbitrarily set as necessary. The purpose is to be able to install a control system for lighting equipment at a location.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the lighting control device of the present invention sets a transmitter / receiver unit that can transmit and receive control signals via a signal line, an external input unit that inputs an operation signal from the operation unit, and its own CH number. The CH setting unit, the storage unit that stores and saves the blinking dimming state of each lighting load corresponding to each lighting scene based on the control signal or the operation signal, and each lighting load individually based on the control signal or the operation signal. It consists of a controller consisting of one or more load control units that control flashing or dimming, and an operating unit and lighting load connected to the controller. The control signal line to be connected is connected in a closed loop, and the operation signal from the operation unit connected to the controller is controlled from the controller to which the operation unit is connected. Converted into signals, it is characterized in that the transmitted originated via the controllers sequentially to the final controller.

[0007]

[Action]

 The operation of this device will be described. If there is an external input (instruction) from the operation unit, if it is the control content related to its own controller (for example, in the case of scene storage, the lighting state of the lighting load connected to its own controller is stored in the storage unit. In the case of scene playback, for example, the corresponding scene state is read from the storage unit and the control state of each lighting load is played back. In addition, if the lighting load blinks and dimming control is performed, the load control in its own controller is performed. Next, when there is a control signal from the previous controller, the processing operation is not performed when the control signal is returned to the transmission source. It is sent to the next controller without change.

【Example】

An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an electric circuit diagram showing an embodiment of the lighting control device of this idea, and FIG. 2 is a block diagram showing a configuration example of a controller in the circuit of the above. The figure will be described. An operating unit such as a wall switch is used for the flashing state of each lighting load L _n (n is 1 to 4, the same applies hereinafter), dimming state instruction, scene (load illumination state) storage, and playback instruction A _n (n is 1 to 2, the same applies hereinafter).

In FIG. 1, the operation units A _n are installed at two places, and are referred to as an operation unit A ₁ and an operation unit A ₂ . The controller C _n (n is 1 to 4, the same applies hereinafter) is wired between the main control unit 6, the external input unit 1 for receiving an operation (instruction) signal from the operation unit A _n , and each controller. A control signal line a connected to the transmitter / receiver 2, a CH setting unit 3 for setting a unique CH number of its own controller C _n , a scene (illumination state of each load L _n connected to its own controller C _n storage unit stores) 4 and the loads L _n (n is 1 to n, hereinafter the same) blinking, dimming multiple load controller 5 _n (n for controlling the 1 ~n, consists of the following the same) Has been done.

Table 1 shows an example of signal contents transmitted and received between the controllers C _n .

[Table 1] X: Basic Y: For all channel control such as scene storage and playback Z: For example, individual load control Basically, it is shown in X, and it can be realized in various coded signal formats such as time division signals, but the content is transmitted based on the signal from the operation unit. There are "originating CH" indicating the CH of the originator, "reception CH" indicating the load of all appliances or a specific appliance, "OPC" indicating the control content, and "OPR". Y indicates an example of scene storage, reproduction, etc. for the control of all appliances (all CHs), and Z indicates an example of individual blinking, dimming, etc. for the load control of a specific device. ing.

FIG. 3 is a flowchart showing an operation example of the controller. First, FIG. 1 for (S ₁ to S ₅₎ of FIG. 3, will be described with reference to FIG. 2, when there is an external input from the operation unit A _n (instruction) if the control contents related own controller C _n (For example, in the case of scene storage, the illumination state of the illumination load L _n connected to its controller C _n is stored in the storage unit 4, and in the case of scene reproduction, for example, the corresponding scene state is stored in the storage unit 4. The read state is reproduced and the control state of each lighting load L _n is reproduced, and if the lighting load L _n blinks and the dimming control is performed, the load control unit 5 _n performs load control.), And the load in its own controller C _n It controls. Next, the CH number set by the CH setting unit 3 is used as the outgoing CH, and a control signal is generated according to the signal format shown in (Table 1) and transmitted to the next controller C _n .

Next, referring to (S _{6 to} S ₁₀ ) of FIG. 3, when there is a control signal from the previous controller C _n, if the outgoing CH is equal to the CH set by the own controller C _n , Does not perform the subsequent processing operation. (That is, when the control signal is returned to the transmission source, the processing operation is not performed.) Then, the control signal is transmitted to the next controller C _n as it is, that is, without changing the content.

Therefore, the controller C _n to which the operation system is connected performs the processing of (S _{1 to} S ₁₀ ) in FIG. 3, and the controller C _n to which the operation system is not connected is shown in (S _{6 to} S ₁₀ ) of FIG. Processing will be performed. In this way, the wiring between the controllers C _n (control signal wiring) is simplified, and the operation system can be arranged as needed without being restricted by the position of the conventional master unit.
