  However, when various functions are mounted on the task light, the task light becomes complicated, and different types of task lights are provided for each function to be mounted. In addition, when linking the lighting state of the task light and the lighting state of the indoor lighting fixture, it may be possible to provide a link function on the task light side, but in that case, a special task having the function is provided. It becomes a light.

  An object of the present invention is to provide an illumination control system that can simplify the function of a task light and link the illumination state of the task light and the illumination state of an indoor lamp to save energy.

  The illumination control system according to the embodiment includes a plurality of lamps that emit light and illuminate an illumination area. A task light for ensuring the brightness required for the worker is arranged in the illumination area. The task light has a function of transmitting the lighting state information. The information terminal receives the lighting state information of the task light. And when the lighting state information of a task light is received, the control information for controlling the lighting of a lamp together with at least its own identification information is transmitted to the lighting base unit based on the lighting state information.

  Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of Example 1 of the illumination control system according to the embodiment of the present invention. The plurality of lamps 11 are arranged on the ceiling portion of the building room, and illuminate the illumination area in the building room by irradiating light.

  The lighting master unit 12 is connected to a plurality of lamps via a transmission line, and remotely controls the plurality of lamps via the transmission line. The lighting master 12 performs, for example, dimming control and lighting on / off control of the illumination area, or group control for collectively turning on / off some of the plurality of lamps in the illumination area. In FIG. 1, three transmission lines are connected to the lighting master 12, and a plurality of lamps are connected to each transmission line.

  The wall switch 13 is connected to one of the three transmission lines connected to the lighting control master unit 12, and is operated, for example, in the lighting area via the lighting master unit 12 by an operation of an operator or the like. Some or all of the plurality of arranged lamps are collectively turned on / off.

  In the illumination area illuminated by the plurality of lamps 11, for example, a desk on which an operator works is installed, and a task light 14 is installed on the desk. In other words, the task light 14 is installed for each work area (here, for each worker's desk) and individually irradiates the work area in order to secure illuminance necessary for the work surface.

  Since the task light 14 is generally installed at a position closer to the work surface than the lamp 11 and is installed for the purpose of irradiating an individual work area, for example, a range narrower than the irradiation range of one lamp 11 It is comprised so that it may irradiate. The task light 14 has a communication function for transmitting its lighting state information.

  Here, the illumination state information of the task light 14 is information indicating, for example, whether the task light 14 is lit or unlit. When the task light 14 has a dimming function, the dimming state is also included in the illumination state information. The task light 14 has a communication function such as an infrared communication function, a USB communication function, a wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), a sound such as a visible light communication function, light, It is possible to use any communication medium using radio waves, cable, or wireless.

  Further, the lighting state information may be transmitted, for example, when the task light 14 is changed from off to on, or may be transmitted for a certain period after the change, or when the task light 14 is changed from on to off. Then, a signal indicating that the light has been turned off may be transmitted for a certain period. It should be noted that “when changed” includes a predetermined time after actual control is performed in consideration of the time or delay time of arithmetic processing. Further, a signal indicating the lighting state may be transmitted constantly or intermittently while the task light 14 is lit, or a signal indicating the lighting state may be transmitted constantly or intermittently while the task light 14 is turned off. Also good.

  In the present embodiment, the task light 14 does not store identification information, allocation information, and the like, and the illumination state information is configured to transmit a very simple signal having a minimum necessary communication capacity capable of distinguishing between the on state and the off state. It can be. For this reason, the communication function of the task light 14 can be simplified.

  The information terminal 15 receives the illumination state information transmitted from the task light 14 and determines the control state of the task light. The information terminal 15 is, for example, a mobile phone such as a smartphone or a PDA (Personal Digital Assistant), and receives, for example, an illumination state information of the task light 14, for example, an infrared communication function, a USB communication function, or Bluetooth or Wi-Fi. Any communication medium using sound, light, radio waves, wired, wireless, etc., such as wireless communication functions such as -Fi and visible light communication functions, can be used.

  The information terminal 15 has allocation information in which at least one lamp of the plurality of lamps 11 and its own identification information (identification ID) are associated in advance, and when the lighting state information of the task light 14 is received. Based on the lighting state information of the task light 14, the lighting control command for the lamp 11 associated with the allocation information is calculated, and the lighting control command is transmitted to the lamp 11 associated with the allocation information.

  Transmission of the illumination control command to the lamp 11 is performed using a communication function between the information terminal 15 and the plurality of lamps 11. Communication between the information terminal 15 and the plurality of lamps 11 is performed using a wireless technology such as Wi-Fi or Bluetooth installed in the information terminal 15. That is, in Example 1 of the embodiment of the present invention, the lamp 11 also has a communication function similar to the task light 14 and the information terminal 15, for example, a wireless communication function such as Wi-Fi or Bluetooth.

  FIG. 2 is a block diagram illustrating an example of the information terminal 15 in Example 1 of the embodiment of the invention. The information terminal 15 receives the illumination state information from the task light 14 by the receiving unit 16 having a communication function such as an infrared communication function or a USB communication function, and stores it in the storage unit 17. The storage unit 17 stores allocation information in which the lamp 11 is associated with its own identification ID in advance. Further, the information terminal 15 is configured to calculate the content of the illumination control command of the lamp 11 for the received illumination state information. For example, when lighting state information is transmitted from the task light 14 as lighting state information, for example, the information terminal 15 transmits a lighting control command for lowering the output to the lamp 11 assigned to its own identification ID. On the other hand, when the light-off state information is transmitted from the task light 14, an illumination control command for returning the output to the original lamp 11 assigned to the information terminal 15 is transmitted. The lamp 11 that has received the illumination control command controls the output in accordance with the received illumination control command. With this control, the work area can secure the required illuminance, and the illuminance can be reduced around the work area.

  That is, when both the lamp 11 and the task light 14 are turned on, the work area is irradiated with light by both the lamp 11 and the task light 14. Here, if the light from the task light 14 is added in a state where the required illuminance of the illumination area is secured only by the lamp 11 in advance, the illuminance of the work surface exceeds the required illuminance. In addition, when the task light 14 is turned on, it can be considered that the task light 14 is in a work area, so even if the illuminance around the work area is reduced, the influence on the worker is low. Therefore, when the task light 14 is lit when the lamp 11 is lit, the output of the lamp 11 is reduced to control the illuminance in the work area to a constant level and to reduce the illuminance outside the work area. To save energy. In other words, when working in the work area with the task light 14 lit, by ensuring the illuminance on the desk surface in the work area and intentionally creating an illuminance difference between the work area and outside the work area The energy outside the work area is reduced to save energy.

  In the present embodiment, paying attention to the information terminal 15 carried by the worker, the lamp 11 and the identification ID of the information terminal 15 are associated in advance, and the information is stored in the information terminal 15 in advance as allocation information. It was. This is because the worker mostly works at his / her desk in the office, and the information terminal 15 carried by the worker is considered to be equivalent to the task light 14 placed on the desk.

  Thus, by associating the lamp 11 to be controlled with the information terminal 15, it is not necessary to give an identification ID to the task light 14, and the task light 14 simply outputs the illumination state information. The communication function of the task light 14 can be simplified, and the task light 14 can be used without setting the task light itself. For this reason, the task light 14 can be easily introduced when the task light 14 is added or changed.

  In this embodiment, it is only necessary that the lamp 11 to be controlled can be set for the information terminal 15, and the identification ID and the allocation information between the identification ID and the lamp 11 stored in the information terminal 15 are indispensable configurations. Absent. That is, the information terminal 15 only needs to be able to identify the lamp 11 that transmits the lighting control command when receiving the lighting state information from the task light 14.

  The information terminal 15 shown in FIG. 2 shows a case where its own identification ID is X and the associated lamp number is i. The computing unit 18 computes an illumination control command for the lamp i associated with the allocation information based on the illumination state information and the allocation information of the task light 14 and updates and stores it in the storage unit 17.

  For example, when the lighting state information of the task light 14 is lighting state information, a lighting control command for reducing the brightness is calculated as the lighting control command for the lamp i. When the illumination state information of the task light 14 is the extinguishing state information, an illumination control command for normal brightness without dimming is calculated as the illumination control command for the lamp i. In this case, an illumination control command that adopts an illumination control command from the illumination master unit 12 may be used. Further, when the lighting state information of the task light 14 is dimming state information, an lighting control command for the brightness reduced according to the dimming level is calculated as the lighting control command for the lamp i.

  As described above, the transmission unit 19 has a wireless communication function such as Wi-Fi or Bluetooth, and transmits an illumination control command to the lamp i updated and stored in the storage unit 17 to the lamp i. As a result, the lighting of the lamp i is controlled by the lighting control command from the information terminal X.

  Next, how to set the allocation information will be described. The information terminal 15 displays a layout diagram of the illumination area illuminated by the plurality of lamps 11, and assigns the information terminal 15 and one of the plurality of lamps 11 in the illumination area via the layout diagram. Do. For example, the information terminal 15 obtains a layout diagram of the illumination area from the illumination master unit 12.

  FIG. 3 is an explanatory diagram of an example of a layout diagram of the illumination area. In the layout diagram of the building room, a plurality of lamps 11 and the arrangement positions of desks on which workers work are described. Since the task light 14 is arranged on each desk, the correspondence between the lamp 11 and the task light 14 can be specified from the lamp 11 and the arrangement position of the desk.

  Since the worker is provided with a desk on which the worker always works, the desk can be associated with the worker, and the information terminal 15 carried by the worker can be associated with the desk. Therefore, the lamp 11 and the task light 14 can be associated with each other by associating the lamp 11 with the information terminal 15.

  FIG. 3 shows a case where the lamp 11 and the desk are arranged in a one-to-one relationship. Therefore, the lamp 11 and the information terminal 15 (task light 14) carried by the worker have a one-to-one correspondence. Yes.

  In setting the allocation information in the information terminal 15, the information terminal 15 obtains a layout diagram of the illumination area and displays a layout diagram screen as shown in FIG. 3 on the display unit of the information terminal 15, for example. The worker determines the position of his / her desk and touches the position of his / her desk on the screen of the layout diagram. When the own desk is at the position of the lamp number 3, the position of the lamp number 3 on the screen of the layout diagram is touched. Thereby, when the identification ID of the information terminal 15 carried by itself is C, the allocation information having the identification ID of C and the lamp number of 3 is set in the storage unit of the information terminal 15 of its own.

  In the above description, the case where the lamp 11 and the desk are arranged on a one-to-one basis has been described, but the present invention can also be applied to the case where the lamp 11 and a desk are arranged on a one-to-n basis. In that case, the correspondence between the lamp 11 and the information terminal 15 is 1 to n.

  Moreover, about the setting of allocation information, you may make it set with the illumination main | base station 12, and you may make it transmit to each information terminal 15. FIG. In this case, the information terminal 15 carried by the worker and the position of the desk given to the worker are inputted in advance to the lighting master unit 12, and the lighting master unit 12 takes the information terminal 15 carried by the worker and the desk given to the worker. The allocation information is created based on the position and layout diagram. And it transmits to the information terminal 15 from the illumination main | base station 12, and allocation information is set to the information terminal 15. FIG. Transmission from the lighting master 12 to the information terminal 15 may be performed directly using a wireless communication function such as Wi-Fi or Bluetooth, or may be transmitted via the Internet.

  According to Example 1 of the embodiment of the present invention, since the illumination state of the task light 14 and the illumination control system are linked, unnecessary light can be reduced and energy saving can be achieved. Further, since only the communication function for transmitting the illumination state information needs to be added to the task light 14, the configuration of the task light can be simplified and the task light itself can be omitted. Furthermore, since an illumination control command according to the illumination state of the task light 14 can be performed on the information terminal side, various detailed settings such as arithmetic processing, assignment work, and change of control contents can be easily performed on the information terminal. .

  Next, Example 2 of the illumination control system according to the embodiment of the present invention will be described. FIG. 4 is a configuration diagram of Example 2 of the lighting control system according to the embodiment of the present invention. The second embodiment is different from the first embodiment shown in FIG. 1 in that the lighting control command is output from the information terminal 15 to the lamp 11 to control the lighting of the lamp 11, and the lighting master 12 to the lamp 11. An illumination control command is output to control the illumination of the lamp 11. The same elements as those in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.

  As in the case of the first embodiment, the information terminal 15 has allocation information in which any one of the plurality of lamps 11 is associated with its own identification ID in advance, and receives the lighting state information of the task light 14. When it does, based on the lighting state information of the task light 14, the lighting control content of the lamp 11 associated with the allocation information is calculated. Then, the calculated lighting control content of the lamp 11 is output to the lighting master unit 12.

  The lighting master unit 12 remotely controls the plurality of lamps 11. When the lighting control content of the lamp 11 is received from the information terminal 15, the information is replaced with the lighting control content calculated by the lighting master unit 12. The illumination control content received from the terminal 15 is output to the lamp 11 as an illumination control command. Thereby, the lighting of the lamp is controlled according to the lighting control content calculated by the information terminal 15.

  The communication between the lighting master 12 and the information terminal 15 is similar to the communication between the information terminal 15 and the plurality of lamps 11, such as Wi-Fi or Bluetooth generally installed in the information terminal 15. You may make it implement using a radio | wireless technique and may communicate via the internet.

  FIG. 5 is a block diagram showing an example of the information terminal 15 in Example 2 of the embodiment of the invention. As in the case of the first embodiment, the storage unit 17 stores allocation information in which any one of the plurality of lamps 11 is associated with its own identification ID in advance, and the calculation unit 18 receives the reception unit 16. The lighting control content of the lamp i associated with the allocation information is calculated and updated and stored in the storage unit 17 on the basis of the illumination state information of the task light 14 received in step S4 and the allocation information stored in the storage unit 17.

  The transmission unit 19 transmits the illumination control content for the lamp i updated and stored in the storage unit 17 to the illumination master unit 12. When the lighting control unit 12 receives the lighting control content of the lamp i from the information terminal X, the lighting control content received from the information terminal X is used instead of the lighting control content calculated by the lighting base unit 12. Is output as an illumination control command. Thereby, the lighting of the lamp i is controlled according to the lighting control content calculated by the information terminal X.

  According to Example 2 of the embodiment of the present invention, since the lamp 11 is controlled by the illumination control command from the illumination master unit 12, the illumination control of the plurality of lamps 11 is uniformly performed by the illumination master unit 12. Can do.

  In the above description, the allocation information is given to the information terminal 15, but the lighting master unit 12 may be given. FIG. 6 is a block configuration diagram of the information terminal 15 when the allocation information is given to the lighting base unit 12, and FIG. 7 is a block configuration diagram of the lighting base unit 12 when the allocation information is given to the lighting base unit 12. .

  When the allocation information is given to the lighting master unit 12, as shown in FIG. 6, the information terminal 15 stores its own identification ID instead of the allocation information. When the lighting state information of the task light 14 is received, the lighting control content of the lamp is calculated based on the lighting state information, and the lighting control content and the self identification ID are output to the lighting master unit 12.

  On the other hand, as shown in FIG. 7, the lighting master unit 12 stores allocation information in the storage unit 21. The lighting master 12 receives the lighting control content of the lamp 11 and the identification ID of the information terminal 15 from the information terminal 15 by the receiving unit 20 and updates and stores them in the storage unit 21. The calculation unit 22 identifies the lamp 11 associated with the allocation information based on the identification ID and the allocation information of the information terminal 15 updated and stored in the storage unit 21. Further, the calculation unit 22 calculates a lighting control command for the specified appliance 11 based on the lighting control content of the lamp 11 updated and stored in the storage unit 21, and stores it in the storage unit 21.

  The transmission unit 23 transmits the illumination control command for the lamp 11 updated and stored in the storage unit 21 to the lamp 11. Thereby, the lighting of the lamp 11 is controlled according to the lighting control command from the information terminal 15. Thus, even when the allocation information is given to the lighting master unit 12, the same effect as that of Example 2 of the embodiment of the present invention can be obtained.

  The embodiments of the present invention are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof. For example, the light source may be common for white and red (or yellow), and the filter member may function with respect to light emitted in either direction.
