  An illumination control system according to an embodiment of the present invention will be described with reference to the drawings. The same or corresponding components are denoted by the same reference numerals, and repeated description may be omitted.

Embodiment 1 FIG.
FIG. 1 is a block diagram of a lighting control system according to Embodiment 1 of the present invention. The illumination control system includes a controller 10. The controller 10 communicates with the communication units 12 and 30 by wireless signals or wired signals.

  A first lighting device 14 is connected to the communication unit 12. The first lighting device 14 is provided with a control unit 16 that functions as a lighting circuit and an LED power source 18 that is controlled by the control unit 16. The first lighting device 14 is a light control lighting device capable of changing the light control rate. You may change LED into a fluorescent lamp or an incandescent lamp.

  The communication unit 12 is connected with a human sensor 20 that detects the presence of a person in the area, an illuminance sensor 22 that similarly detects the illuminance in the area, and a wall switch 24 that turns on and off the first lighting device 14. . The first lighting device 14, the human sensor 20, the illuminance sensor 22, and the wall switch 24 are connected to the communication unit 12 via a signal line that performs bidirectional communication by two-wire serial communication.

  The communication unit 30 is connected to the second lighting device 32, the third lighting device 40, and the wall switch 48. The second lighting device 32 includes a light bulb color LED power source 36, a daylight white LED power source 38, and a control unit 34 for controlling them. The control unit 34 has two outputs for individually generating a dimming rate signal (PWM signal or digital signal) to the light bulb color LED power source 36 and the daylight white LED power source 38.

  The control unit 34 calculates the dimming balance between the light bulb color LED power source 36 and the daytime white LED power source 38, and realizes the commanded dimming rate and color temperature. That is, the second lighting device 32 is a color variable lighting device. The control unit 34 may be omitted, and the light bulb color LED power source 36 and the daylight white LED power source 38 may receive signals from the communication unit 30. Other control units can be omitted as well.

  The third lighting device 40 includes a condensing unit LED power source 44, a diffusion unit LED power source 46, and a control unit 42 for controlling them. FIG. 2 is a perspective view of the third lighting device 40. There is a condensing part 44a in the central part of the light source, and a diffusion part 46a in the outer part of the light source. The third illuminating device 40 is a light source having a downlight shape in which the light condensing unit 44a and the diffusing unit 46a are controlled by two separate circuits.

  Returning to the description of the third lighting device 40 of FIG. The control unit 42 has two output units for individually generating a dimming rate signal (PWM signal or digital signal) to the power supply 44 for the condensing unit LED and the power supply 46 for the diffusion unit LED. The condensing unit LED power source 44 and the diffusion unit LED power source 46 are controlled according to the received dimming rate signals, thereby obtaining an arbitrary light distribution. That is, the 3rd lighting device 40 is a lighting device for variable light distribution. Thus, the 1st lighting device 14, the 2nd lighting device 32, and the 3rd lighting device 40 have a different function, respectively.

  The lighting control system includes a remote controller 50 that sets functions of the controller 10 and the like by a user's remote operation. Further, a PC setting unit 52 used for setting functions from a personal computer screen or monitoring the state of the system is provided. The remote controller 50 and the PC setting device 52 communicate with the controller 10 or the communication units 12 and 30 in a wired or wireless manner.

  A gateway 60 and a central management device 62 are wired to the controller 10. The gateway 60 and the central management device 62 correspond to the host system of the controller 10. The gateway 60 has a conversion function between wired serial communication to which the controller 10 is connected and Ethernet (registered trademark), and is a part that transmits and receives data. The controller 10 sets the lower system of the communication units 12 and 30 and manages the control state. The central management device 62 performs system setting, status monitoring, and collective control of one or a plurality of controllers 10. The central management device 62 is a personal computer, for example. Since the interface of the central management device 62 is Ethernet (registered trademark), the central management device 62 can be linked with other equipment such as an air conditioner. By setting from the central management device 62, dimming control, and status monitoring, it is possible to monitor the dimming control or failure status of the lighting devices 14, 32, and 40.

  A control command is transmitted from the controller 10 to the first lighting device 14, the second lighting device 32, and the third lighting device 40 via the communication units 12 and 30. FIG. 3 is a diagram illustrating information included in the control command. The control command includes control information including a plurality of parameters and discrimination information indicating whether each of the plurality of parameters is valid or invalid. First, control information will be described. The control information includes dimming rate, fade time, color temperature, and light distribution parameters. Here, a dimming command command is illustrated as the control command.

  Since the light control rate is determined in the range of 0% meaning off and 100% meaning all lights, it is any value from 0 to 100%.

  The fade time is the time spent transitioning to a predetermined dimming rate. In other words, the fade time represents the time (seconds) spent until a predetermined dimming rate is realized 100%. When the fade time is 0 seconds, no fade is applied. When the fade time is 4680 seconds, fade control is performed with a slope (change in the light control rate per unit time) that takes 4680 seconds to achieve a predetermined light control rate of 100%. For example, when the fade time is 0 to 180 seconds, the dimming rate can be changed in units of 1 second, and when the fade time is 181 to 4680 seconds, the dimming rate can be changed in units of 60 seconds. Although the fade time is described as the time spent for the dimming rate to change by 100%, the fade time is not limited to this. For example, the dimming rate is 10%, and the time is represented by the time per 1%. Also good.

  The color temperature is expressed in Kelvin [K], and for example, 2000 to 7000 K is set as the designated range. Instead of using Kelvin as a unit, the color temperature may be indicated by coordinates of the chromaticity diagram or RGB values.

  The light distribution (condensation rate) indicates the balance of brightness between the condensing unit 44a at the center of the light source and the diffusion unit 46a outside the condensing unit 44a. When only the condensing part 44a is lit, the condensing rate is 100%, the lighting rate of the condensing part 44a is 100%, and the lighting rate of the diffusing part 46a is 0%. On the other hand, when only the diffusion part 46a is lit, the light collection rate is 0%, the lighting rate of the light collection part 44a is 0%, and the lighting rate of the diffusion part 46a is 100%. When the ratio of the light control rate between the light collecting unit 44a and the diffusion unit 46a is 1: 1, the light collection rate is 50%, and the lighting rate of the light collecting unit 44a and the lighting rate of the diffusion unit 46a are 50%. . Thus, the ratio of the lighting rate is appropriately changed according to the light distribution desired to be realized.

  Each of the four parameters of the control information is a 1-byte data amount. Therefore, the control information as a whole has a data amount of 4 bytes.

  Next, the discrimination information will be described. The discrimination information is 1-byte information, and is roughly classified into upper 4 bits information and lower 4 bits information.

  The upper 4 bits of the discrimination flag (discrimination information) indicate whether the four parameters of the dimming rate, the fade time, the color temperature, and the light distribution (condensing rate) are valid. When the corresponding bit is 1, it is valid, when it is 0, and when a plurality of parameters are valid at the same time, the plurality of bits are simultaneously set to 1. For example, if all parameters are valid, all are set to 1. The controller 10 transmits a control command including control information and discrimination information via the communication units 12 and 30 with different types of first to third lighting devices 14, 32 and 40 in the same system as command destinations. This transmission is a single transmission.

  The first lighting device 14 that has received the control command, when the first parameter (dimming rate) that is a parameter to be reflected in the control of the first lighting device 14 among the plurality of parameters is enabled by the discrimination information, It operates according to the first parameter (dimming rate) included in the control information.

  When the second lighting device 32 receives a control command transmitted at the same timing as the first lighting device 14, the second lighting device 32 is a second parameter (a dimming rate and a parameter that is reflected in the control of the second lighting device 32 among a plurality of parameters). When the color temperature is validated by the discrimination information, the operation is performed according to the second parameter (light control rate and color temperature) included in the control information.

  When the third lighting device 40 receives a control command transmitted at the same timing as the first and second lighting devices 14 and 32, a third parameter that is reflected in the control of the third lighting device 40 among a plurality of parameters. When (light distribution and dimming rate) is validated by the discrimination information, the operation is performed according to the third parameter (light distribution and dimming rate) included in the control information. The fade time information included in the control information is reflected in at least one control of the first to third lighting devices 14, 32, 40.

  As described above, the controller 10 transmits the control command of the common format only once to the different types of the first to third lighting devices 14, 32, and 40 in the same system as the command destination. Can be controlled simultaneously. In addition, each lighting device that has received the control command confirms a valid parameter based on the discrimination information, and then performs dimming control according to the parameter having the function of the lighting device itself. The first to third lighting devices 14, 32, and 40 can select and control only necessary parameters from the received common format control information. In this way, by providing one common control command for a plurality of lighting devices, the controller recognizes the type of lighting device connected to the controller and provides a control command for each lighting device. Data communication can be simplified. That is, since the data communication between the controller 10 and the plurality of lighting devices is simplified by using the above control command, the plurality of lighting devices can be controlled quickly.

  The lower 4 bits (hereinafter referred to as control type information) of the discrimination flag (discrimination information) indicate the type of control managed by the controller 10. The control type information is used when any of the lighting devices includes a plurality of light sources. The control type information indicates the type of control for at least one of the plurality of light sources. The control type information is information indicating any one of manual control, automatic control, illuminance sensor control, and human absence control.

  Manual control is user operation or temporary dimming rate control. Automatic control is normal control performed so as to realize a target value of control. The illuminance sensor control is feedback control of the lighting device based on the illuminance value of the space detected by the illuminance sensor 22. The human absence control is light control based on a human body detection state by the human sensor 20. Any one of these controls is selected and transmitted as information of the lower 4 bits of the discrimination information.

  The control type information (lower 4 bits of the discrimination flag) is provided, for example, so that the control unit 16 has a plurality of group numbers and operates with priority when receiving a dimming command for each group. The prioritized control type information is stored in advance in the memory of the control unit 16. For example, even when the illuminance sensor control of a certain group is received, the control unit 16 performs the extinguishing control with higher priority than the illuminance sensor control when receiving the presence absence control by another group. In addition, even when the control unit 16 receives a dimming rate instruction by automatic control in a certain group, if the control unit 16 receives manual control meaning forced control by another group, the dimming rate by automatic control is received. The dimming rate is determined according to the dimming rate by manual control having a higher priority than the instruction. When there is no group number and it is not necessary to have the priority of dimming control, the control type information (the lower 4 bits of the discrimination flag) may be unused. As described above, when the control unit issues a command to a plurality of groups, appropriate control can be performed by setting the priority of control according to the control type information. Here, a case has been described in which the control unit 16 performs control by changing to control having higher priority than the received control information. However, if the received control information has higher priority, the control unit 16 executes without change. You may make it do.

  FIG. 4 is a functional block diagram of the controller and control unit according to Embodiment 1 of the present invention. The controller 10 includes an input unit 10 a that receives information for generating a control command, a control command generation unit 10 b that calculates a control command, and an output unit 10 c that transmits the control command to the communication units 12 and 30.

  In the control unit 16 (the same applies to the control units 34 and 42), the input unit 16a that receives the control command and the first parameter (dimming rate) that is a parameter to be reflected in the control of the first lighting device 14 are validated by the discrimination information. The determination part 16b which determines whether it is is provided. Furthermore, the control part 16c which controls the LED power supply 18 so that a 1st parameter is extracted and a 1st parameter is implement | achieved when the determination part 16b determines with a 1st parameter being effective is provided.

  FIG. 5 is a hardware configuration diagram of the controller 10 and the control unit 16 according to the first embodiment of the present invention. The aforementioned input unit 10a is the receiving device 10A, and the output unit 10c is the transmitting device 10D. The control command generation unit 10b is realized by a memory 10C and a processor 10B (for example, a processing circuit such as a CPU or a system LSI) that executes a program stored in the memory 10C. A plurality of processing circuits may cooperate to execute the function of the control command generation unit 10b.

  The control unit 16 includes a receiving device 16A, a processor 16B, a memory 16C, and a transmitting device 16D. The aforementioned input unit 16a is the receiving device 16A. The determination unit 16b and the control unit 16c include a memory 16C, a processor 16B (for example, a processing circuit such as a CPU or a system LSI) that executes a program stored in the memory 16C, and a transmission device 16D that outputs a control signal to the LED power source 18. Realized. A plurality of processing circuits may cooperate to execute the above function. When the controller 10 and the control unit 16 perform two-way communication such as digital communication, as shown in FIG. 4, the control unit 16 sends a return output unit for returning the status monitor from the control unit 16 to the controller 10. What is necessary is just to mount 16d.

  The lighting control system according to Embodiment 1 of the present invention can be variously modified. For example, the content of the control command can be appropriately changed according to the content of the target control. A plurality of lighting fixtures (LEDs) may be controlled by one output from the control unit. The number of lighting devices, human sensors, illuminance sensors, or wall switches connected to one communication unit can be changed according to the aspect of the lighting control system to be constructed. Illustrative examples of the lighting device include a dimming lighting device, a color variable lighting device, and a light distribution variable lighting device, but are not limited thereto. Moreover, although the communication unit 12 illustrated a system configuration in which one type of the first lighting device 14 and two types of the first and second lighting devices 32 and 40 are connected to the communication unit 30, the system configuration is not limited thereto. It is possible to construct a system configuration with various combinations.

  The control units 16, 34, and 42 are portions that receive control commands from the communication units 12 and 30 and convert them into dimming signals (for example, PWM signals) to the light source. The LED power supply may directly receive a control command and perform dimming control without mounting a control unit. When using a lighting device capable of dimming by digital communication control, the control of the lighting device and status monitoring can be realized by performing digital communication control in the control unit. In order to perform status monitoring by performing digital communication control, in the functional block diagram of the control unit (FIG. 4), a return output unit 16d for returning an input monitor command is provided on the upper side. That's fine. These modifications can be applied as appropriate to the illumination control systems according to the following embodiments. Since the illumination control system according to the following embodiment has a lot in common with the first embodiment, the description will focus on the differences from the first embodiment.

Embodiment 2. FIG.
In the second embodiment of the present invention, a method for generating a control command by the controller 10 will be described. The configuration of the illumination control system is as shown in FIG. The human sensor 20, the illuminance sensor 22, and the wall switch 24 communicate with the controller 10 in a wired or wireless manner. Then, the controller 10 creates a control command from the detection results of the human sensor 20 and the illuminance sensor 22 and the operation state of the wall switch 24. This will be specifically described below.

  The human sensor 20 notifies the controller 10 of information such as the presence / absence information of the person and the movement speed of the person. When the human sensor 20 detects the presence of a person, the controller 10 transmits a control command including a lighting instruction to the lighting device (first lighting device 14) having the same group number as the human sensor 20. When the human sensor 20 detects the absence of a person, a control command including an instruction to turn off or dimm the lighting device (first lighting device 14) having the same group number as the human sensor 20 is transmitted.

  The illuminance sensor 22 converts the detected brightness of the desk top surface or floor surface into an illuminance value [lx] based on preset information, and transmits the illuminance value information to the controller 10. When the controller 10 receives the illuminance value information, the controller 10 calculates a dimming rate so as to achieve a preset target brightness, and transmits a control command to realize the dimming rate.

  The wall switch 24 has a plurality of buttons to which different functions are assigned. The correspondence between the buttons and functions is stored in the wall switch 24 or the controller 10. Each function is operated when the button of the wall switch 24 is pressed. Functions that can be assigned to buttons include lighting / extinguishing individual lighting devices, dimming rate up / down, lighting device group unit lighting / extinguishing, dimming rate up / down, large group control, pattern control, and setting There is pattern control. The large group control is to collectively control a plurality of groups including a plurality of lighting devices.

The following functions are assigned to the plurality of buttons of the wall switch 24.
-Function to turn on / off lighting device individually or in groups-Function to increase or decrease the dimming rate of lighting device by 1% each time wall switch 24 is pressed-Further group multiple groups as large group control Function to control as a large group-The dimming rate is registered in the controller 10 in advance so that the dimming rate of each of the plurality of lighting devices becomes an arbitrary dimming rate, and the button of the wall switch 24 is For example, target illuminance, target dimming rate, upper limit dimming rate, lower limit dimming rate, as a parameter to be used for pattern control function / illumination control to generate a control command that realizes the registered dimming rate by pressing A setting pattern function that registers the fade time and the operation mode of the motion sensor 20 in advance and changes to the registered setting parameters by pressing the button of the wall switch 24.

  With these functions, a dimming command command is transmitted from the controller 10 to the lighting device, and at that time, control by the communication format shown in the first embodiment is realized.

Embodiment 3 FIG.
FIG. 6 is a diagram illustrating an illumination control system according to the third embodiment. By realizing the functions of the communication units 12 and 30 shown in FIG. 1 with the controllers 10 and 31, the communication unit is omitted. As a result, the controller 10 is directly connected to the first lighting device 14, the human sensor 20, the illuminance sensor 22, and the wall switch 24. The controller 31 is directly connected to the second lighting device 32, the third lighting device 40 and the wall switch 48. In this way, the configuration can be simplified by omitting the communication unit and realizing the function by the controller.

Embodiment 4 FIG.
The lighting control system according to Embodiment 4 is registered in advance so as to change the lighting / light-off state and dimming rate of the lighting device as time elapses. Equipped with a schedule function to change the light rate. The schedule function may be installed in any device of the controller 10, the gateway 60, or the central management device 62.

  An example of the schedule function will be described. For example, year, month, day, day of the week, hour, minute, and second are registered in the controller 10 in advance, and the microcomputer real-time clock function and real-time clock IC are installed to manage the year, month, day, and time. To do. As a schedule function, a time table for one day is stored by managing a database in which time is associated with dimming rate, color temperature, and light distribution data. This database is stored in the memory of the controller 10, for example. You may memorize | store in the memory outside a controller. Then, at a time determined in advance in the time table, a control command for changing the lighting / extinction state or the dimming rate is transmitted based on the contents stored in the memory.

  For example, you can set a weekly schedule that assigns a daily setting pattern for each day of the week, or set an annual schedule that has priority over a weekly schedule at a specific date and time of the year. Dimming rate, color temperature, and light distribution can be realized. In the central management device 62, a schedule function linked to facilities other than lighting (such as air conditioning or entrance / exit security) may be realized.

  By implementing the schedule function using the control command of the present invention, it is possible to quickly realize any light control rate, color temperature, and light distribution. Note that the controller 10 does not have a scheduling function, but the host system may have a scheduling function. The features described in the embodiments described so far may be combined as appropriate.
