Embodiment 1 FIG.
The configuration of the system and apparatus according to the present embodiment and the effects of the present embodiment will be described in order.

*** Explanation of configuration ***
With reference to FIG. 1, the structure of the illumination system 10 which is a system based on this Embodiment is demonstrated. Moreover, with reference to FIG.1, FIG.2, FIG.3 and FIG. 4, the structure of the infrared communication device 20 which is an apparatus which concerns on this Embodiment is demonstrated.

  The lighting system 10 includes a lighting control system 11 and a lighting fixture 12. Although the number of the lighting fixtures 12 may be one, in this Embodiment, it is two or more.

  The lighting control system 11 includes an infrared communication device 20, and includes a terminal 13, a lighting controller 14, a wall switch 15, a human sensor 16, and an illuminance sensor 17. The number of terminals 13 and lighting controllers 14 may be two or more, but in the present embodiment, each is one. The number of the wall switch 15, the human sensor 16 and the illuminance sensor 17 may be 0 or 1, respectively, but in the present embodiment, it is 2 or more.

  The infrared communication device 20 includes a case 21, and includes a communication interface unit 30, a printed circuit board 40, a signal processing unit 50, a light receiving unit 60, and a light emitting unit 70.

  The communication interface unit 30 has a terminal 31. The terminal 31 is used by being inserted into an external communication port 91. In the present embodiment, since the communication port 91 is a USB (Universal Serial Bus) port, the terminal 31 of the communication interface unit 30 is a USB terminal. The communication port 91 may correspond to a standard or specification other than USB, and in any case, the terminal 31 of the communication interface unit 30 only needs to correspond to the same standard or specification as the communication port 91. .

  The communication interface unit 30 inputs an input signal 92 from the communication port 91 to the signal processing unit 50. Further, the communication interface unit 30 outputs an output signal 93 from the signal processing unit 50 to the communication port 91.

  The printed board 40 is a double-sided mounting type board. On the front surface 41 of the printed circuit board 40, an infrared receiving circuit 52 that is a part of the signal processing unit 50 and a light receiving unit 60 that is electrically connected to the infrared receiving circuit 52 are arranged. On the back surface 42 of the printed circuit board 40, a microcomputer 51 and an infrared transmission circuit 54, which are the remaining part of the signal processing unit 50, and a light emitting unit 70 electrically connected to the infrared transmission circuit 54 are arranged. . Instead of the microcomputer 51, a logic IC, an ASIC (specific application IC), or an FPGA (field programmable gate array) may be used. Moreover, how each part is divided and arrange | positioned into the front surface 41 and the back surface 42 of the printed circuit board 40 can be changed suitably. Further, two or more microcomputers 51 may be provided and arranged on the front surface 41 and the back surface 42, respectively.

  The signal processing unit 50 processes a reception signal 94 from the illumination controller 14 that is an external device and a transmission signal 95 to the illumination controller 14. Specifically, the signal processing unit 50 generates an output signal 93 to the communication port 91 in response to the received signal 94 from the lighting controller 14. Further, the signal processing unit 50 generates a transmission signal 95 to the illumination controller 14 in response to the input signal 92 from the communication port 91. More specifically, the signal processing unit 50 receives the infrared signal pulse-modulated by the illumination controller 14 using the data code for illumination control as the reception signal 94 by the light receiving unit 60, demodulates the reception signal 94, and demodulates the electrical signal. The electrical signal is output to the communication port 91 as an output signal 93. Further, the signal processing unit 50 performs pulse modulation on the infrared signal amplitude-modulated with the carrier wave by the input signal 92 which is an electric signal input from the communication port 91 or the data code obtained from the input signal 92, and the infrared signal is converted into the infrared signal. The light emitting unit 70 transmits the transmission signal 95.

  In the present embodiment, the signal processing unit 50 includes a plurality of electronic components that are separately mounted on both sides of the printed circuit board 40. Specifically, the signal processing unit 50 includes each component of the infrared receiving circuit 52 mounted on the front surface 41 of the printed circuit board 40, the microcomputer 51 mounted on the back surface 42 of the printed circuit board 40, and infrared transmission. It consists of each part of the circuit 54. The infrared communication device 20 can be reduced in thickness by configuring the signal processing unit 50 as described above.

  The light receiving unit 60 receives the reception signal 94 from the illumination controller 14 as infrared light. In the present embodiment, the light receiving unit 60 is an infrared light receiving element.

  The light emitting unit 70 emits a transmission signal 95 to the illumination controller 14 as infrared light. In the present embodiment, the light emitting unit 70 is an infrared light emitting element.

  In the case 21, a communication interface unit 30, a printed circuit board 40, a signal processing unit 50, a light receiving unit 60, and a light emitting unit 70 are installed. In the present embodiment, the case 21 has a box shape extending longitudinally from the one end surface 22 toward the other end surface 23.

  The light emitting unit 70, the signal processing unit 50, and the communication interface unit 30 are sequentially installed from the one end surface 22 of the case 21 toward the other end surface 23. Specifically, the light emitting unit 70 is accommodated in the end 24 having the one end surface 22 among the longitudinal ends 24 and 25 of the case 21. The signal processing unit 50 is accommodated between both end portions 24 and 25 of the case 21. A portion of the communication interface unit 30 excluding the terminal 31 is accommodated in an end portion 25 having the other end surface 23 among the longitudinal end portions 24 and 25 of the case 21. The terminal 31 of the communication interface unit 30 protrudes from the other end surface 23 of the case 21.

  The arrangement of the light receiving unit 60 is substantially the same as the arrangement of the light emitting unit 70, but a part of the light receiving unit 60 protrudes from one end surface 22 of the case 21 and the remaining part is both ends of the case 21 in the longitudinal direction. Of the portions 24 and 25, the end portion 24 having the one end face 22 is accommodated.

  As described above, in the present embodiment, the arrangement of the constituent elements of the infrared communication device 20 is the light receiving unit 60, the light emitting unit 70, the signal processing unit 50, and the communication interface unit 30 in this order. The infrared communication device 20 can be easily grasped without covering the unit 60 and the light emitting unit 70 with hands. Therefore, light reception and emission from the light receiving unit 60 and the light emitting unit 70 are not hindered by the user's hand, and communication can be reliably performed with respect to the target device. Furthermore, by making the light receiving direction of the light receiving unit 60 and the light emitting direction of the light emitting unit 70 opposite to the protruding direction of the communication interface unit 30, the user is less likely to be obstructed by hand gripping, and communication with the target device is prevented. It becomes easy to do.

  An opening 61 and a transmission window 71 for passing infrared light from the light emitting unit 70 are formed on one end surface 22 of the case 21. A part of the light receiving unit 60 protrudes from the opening 61. In other words, in the present embodiment, a part of the light receiving unit 60 protrudes from the case 21, whereas the light emitting unit 70 is disposed in the case 21 at a position away from the transmission window 71. For this reason, it is possible to narrow the transmission range (light emission range) of the light emitting unit 70 by increasing the light receiving range of the infrared communication device 20 while increasing the distance between the light emitting unit 70 and the transmission window 71. To facilitate communication.

  The transmission window 71 is smaller in size as viewed from the optical axis direction of the light emitting unit 70 than the light emitting unit 70. Thus, by narrowing the transmission window 71, the transmission range of the light emitting unit 70 can be further narrowed, and communication with the targeted device can be further facilitated. In particular, if communication with the target device is started by using the transmission signal 95 from the infrared communication device 20 as a trigger, the accuracy can be improved without interference with other devices even if the transmission range of the target device is not narrowed. It is possible to communicate between the infrared communication device 20 and the target device.

  In the present embodiment, the one end surface 22 of the case 21 is a rectangular surface. The opening 61 and the transmission window 71 are at positions separated from each other on the diagonal line of the one end surface 22 of the case 21. For this reason, the light receiving unit 60 and the light emitting unit 70 can be installed as far apart as possible, making it difficult to receive the self-transmitting signal.

  A cable 90 having a communication port 91 is connected to the terminal 13. In a state where the terminal 31 of the communication interface unit 30 is inserted into the communication port 91, the terminal 13 inputs the input signal 92 from the communication port 91 to the signal processing unit 50 via the communication interface unit 30. Further, the terminal 13 receives the input of the output signal 93 from the signal processing unit 50 at the communication port 91 via the communication interface unit 30.

  As described above, in the present embodiment, since the terminal 31 is inserted into the communication port 91 of the flexible cable 90, the user is holding the infrared communication device 20 and is at the tip of the infrared communication device 20. The directions of the light receiving unit 60 and the light emitting unit 70 can be freely changed. Therefore, it is possible to more reliably communicate with the target device.

  Note that instead of the terminal 31 being inserted into the communication port 91 of the cable 90, the terminal 31 may be directly inserted into the communication port 91 of the terminal 13 itself. In that case, the user can adjust the orientation of the light receiving unit 60 and the light emitting unit 70 at the tip of the infrared communication device 20 by holding the terminal 13 and changing the orientation of the terminal 13 itself.

  An application that is software for lighting control is installed in the terminal 13. This application has a function of generating, as an input signal 92, a signal that commands lighting, extinguishing, dimming, and the like of the lighting fixture 12 according to a user operation. In addition, this application has a function of acquiring a signal for notifying the state of devices such as the lighting fixture 12 and the lighting controller 14 as an output signal 93 and displaying the state notified by the output signal 93 on the display of the terminal 13.

  The terminal 13 is a portable terminal such as a tablet or a smartphone in the present embodiment, but may be a PC (personal computer) or the like.

  As described above, in the present embodiment, the display corresponding to the display unit of the conventional remote controller and the function for the user to operate are provided in the terminal 13 separate from the infrared communication device 20. For this reason, when it is desired to change the screen display displayed on the display, it is not necessary to replace the infrared communication device 20, and it is only necessary to change the software. When it is desired to add or change an operation that can be performed by the user, neither the infrared communication device 20 nor the terminal 13 needs to be replaced, and the application installed in the terminal 13 need only be updated. Further, it can be combined with various terminals 13 according to the site to be set. Therefore, according to the present embodiment, the expandability of the infrared communication device 20 can be improved.

  The lighting controller 14 receives the transmission signal 95 generated by the signal processing unit 50 according to the input signal 92 input from the terminal 13 as infrared light from the light emitting unit 70, and receives the lighting fixture 12 according to the transmission signal 95. Control. As a specific example, when the input signal 92 is a signal for controlling lighting of the lighting fixture 12, for example, schedule control or group setting, the internal setting information of the lighting controller 14 itself is updated, or the input signal 92 is the lighting fixture. 12 is a signal for instructing lighting of the lighting fixture 12 because the transmission signal 95 generated by the signal processing unit 50 is also a signal for instructing lighting of the lighting fixture 12. Or turn on.

  Moreover, the lighting controller 14 monitors the state of apparatuses, such as the lighting fixture 12 and the lighting controller 14, and when there exists a request | requirement or regularly, the signal which notifies the state is emitted as infrared light. As a specific example, when the signal emitted from the lighting controller 14 is a signal notifying the lighting state of the lighting fixture 12, the signal becomes a reception signal 94, and an output generated by the signal processing unit 50 according to the reception signal 94. Since the signal 93 is also a signal for notifying the lighting state of the lighting fixture 12, the terminal 13 displays the lighting state of the lighting fixture 12 on the display.

  The lighting controller 14 controls the lighting fixture 12 according to not only the transmission signal 95 from the infrared communication device 20 but also the operation of the wall switch 15, the detection state of the human sensor 16, the illuminance value monitored by the illuminance sensor 17, and the like. Control.

  The lighting controller 14 performs bidirectional communication with the lighting fixture 12, the wall switch 15, the human sensor 16, and the illuminance sensor 17 via signal lines. Each lighting fixture 12, wall switch 15, human sensor 16 and illuminance sensor 17 are assigned individual addresses as reference numbers in advance, and can communicate with the lighting controller 14 individually.

  The lighting fixture 12 is a fixture that includes an LED, an organic EL, a fluorescent lamp, or other light source, and a lighting circuit that turns on the light source. The luminaire 12 turns on or off the light source or changes the brightness of the light source in accordance with a signal transmitted from the illumination controller 14.

  The wall switch 15 is operated by the user for lighting control and dimming control of the light source of the lighting fixture 12. When operated by the user, the wall switch 15 notifies the lighting controller 14 of information indicating a state such as on or off.

  The human sensor 16 detects the presence of a person in the surrounding specific area according to the signal transmitted from the lighting controller 14 and notifies the lighting controller 14 of information indicating the detection result.

  The illuminance sensor 17 measures the illuminance in the surrounding specific area in accordance with the signal transmitted from the illumination controller 14 and notifies the illumination controller 14 of information indicating the measurement result.

  The configuration of the case 21 of the infrared communication device 20 will be described with reference to FIGS. 5, 6, 7, and 8 in addition to FIGS. 2, 3, and 4.

  In the present embodiment, the case 21 is configured by fitting an upper case 26 and a lower case 27 together.

  The opening 61 formed in the one end surface 22 of the case 21 is a round hole. The openings 61 are formed in half in the upper case 26 and the lower case 27. The diameter of the opening 61 may be any size, but is 5.5 millimeters in the present embodiment.

  Similar to the opening 61, the transmission window 71 formed on the one end surface 22 of the case 21 is a round hole. The diameter of the transmission window 71 is preferably less than or equal to two-thirds of the diameter of the opening 61, and is 3.2 millimeters in the present embodiment.

  The case 21 has a mortar-shaped region 62 and a flat region 72 on one end surface 22. The opening 61 is formed at the bottom of the recessed area 62. On the other hand, the transmission window 71 is formed in a flat region 72. The light receiving range of the infrared communication device 20 can be set by the inclination angle of the surface extending from the edge of the recessed region 62 to the bottom. The light receiving range may be an arbitrary range, but in the present embodiment, it is a range of −45 ° to 45 °. The edge of the recessed area 62 is circular. The diameter of the edge of the recessed area 62 may be an arbitrary size, but is 9.6 millimeters in the present embodiment.

  The case 21 includes a partition wall 28 provided between the light receiving unit 60 and the light emitting unit 70. For this reason, it is possible to make the self-transmission signal more difficult to receive. Regardless of the presence or absence of the partition wall 28, the microcomputer 51 may perform hardware control such as disconnecting the port so as not to receive the self-transmission signal, and the reception signal 94 during the transmission period. Software control such as disabling may be performed. Further, the printed circuit board 40 between the light receiving unit 60 and the light emitting unit 70 may be lengthened and interposed therebetween to serve as a partition wall.

  Of both end portions 24 and 25 in the longitudinal direction of the case 21, the height of the end portion 24 having the one end surface 22 is higher than the height of the end portion 25 having the other end surface 23. A portion including the end portion 24 having the one end surface 22 and having a high height is a hook portion 96, and a portion including the end portion 25 having the other end surface 23 and having a low height is a grip portion 97. As described above, the infrared communication device 20 has a high height of the portion in which the light receiving unit 60 and the light emitting unit 70 are accommodated, and a low height of a portion to be gripped by the user. The infrared communication device 20 can be easily grasped without covering the 60 and the light emitting unit 70 with hands.

  The case 21 has an inclined portion 98 that is a portion whose height gradually decreases from the one end surface 22 toward the other end surface 23 between both end portions 24 and 25 in the longitudinal direction. The inclined portion 98 is a part of the hook portion 96. The grip portion 97 is connected to the inclined portion 98.

  Since the case 21 has a shape in which both ends in the height direction of the end portion 25 having the other end surface 23 are obliquely chamfered, the case 21 is inserted when the terminal 31 of the communication interface unit 30 is inserted into the communication port 91. It does not hit the peripheral part of the communication port 91. Therefore, the terminal 31 can be smoothly inserted into the communication port 91.

  The case 21 has a region 46 where the nameplate 45 is attached and another region 47 on the bottom surface 29. A plurality of protrusions 48 whose height dimension is larger than the thickness dimension of the nameplate 45 protrude from the other region 47. The position and number of the protrusions 48 may be any position and number, but in the present embodiment, one protrusion 48 is provided at each of the four corners of the bottom surface 29 and one near the center of the bottom surface 29, for a total of five. It has been. By having the convex part 48, it can prevent that the nameplate 45 rubs and the character printed on the nameplate 45 disappears. In addition, instead of the plurality of projections 48 protruding from the other region 47 or the plurality of projections 48 protruding from the other region 47, the region 46 to which the nameplate 45 is attached is more concave than the other region 47. If so, the same effect can be obtained.

*** Explanation of the effect of the embodiment ***
In the present embodiment, an opening 61 and a transmission window 71 for passing infrared light from the light emitting unit 70 are formed on one end surface 22 of the case 21 of the infrared communication device 20. Some are sticking out. For this reason, according to this Embodiment, it can make it easy to communicate with the target apparatus, making the light-receiving range of the infrared communication device 20 wide.

  Moreover, in this Embodiment, the light emission part 70, the signal processing part 50, and the communication interface part 30 are installed in order toward the other end surface 23 from the one end surface 22 of the case 21 of the infrared communication device 20, and the case 21 A terminal 31 of the communication interface unit 30 protrudes from the other end surface 23. For this reason, by connecting the infrared communication device 20 to the display and the terminal 13 having a function for the user to perform an operation, a function equivalent to or higher than that of the conventional remote controller can be realized. Therefore, according to the present embodiment, the expandability of the infrared communication device 20 can be improved. Furthermore, since the user can easily grasp the infrared communication device 20 without covering the light emitting unit 70 with his / her hand, the user can reliably communicate with the target device.

*** Other configurations ***
In the present embodiment, the luminaire 12 is controlled by performing communication between the infrared communication device 20 and the illumination controller 14, but as a modification of the present embodiment, the infrared communication device 20 and the luminaire. The luminaire 12 may be controlled by performing direct communication with the luminaire 12.

  With reference to FIG. 9, the structure of the illumination system 10a which is a system which concerns on the modification of this Embodiment is demonstrated.

  The lighting system 10a includes an infrared communication device 20, and includes a lighting fixture 12a, a terminal 13, a wall switch 15, a human sensor 16, and an illuminance sensor 17.

  The infrared communication device 20 is the same as the infrared communication device 20 of the lighting system 10 except that the communication partner is not the lighting controller 14 but each lighting fixture 12.

  The terminal 13 is the same as the terminal 13 of the lighting system 10.

  The luminaire 12 a receives the transmission signal 95 generated by the signal processing unit 50 according to the input signal 92 input from the terminal 13 as infrared light from the light emitting unit 70, and is turned on or off according to the transmission signal 95. Or change the brightness.

  Moreover, the lighting fixture 12a emits the signal which notifies the state of the lighting fixture 12a as infrared light, when there exists a request | requirement or regularly.

  The lighting fixture 12a is an appliance including an LED, an organic EL, a fluorescent lamp, or another light source, and a lighting circuit that turns on the light source, like the lighting fixture 12 of the lighting system 10.

Embodiment 2. FIG.

Part 70. In the present embodiment, the infrared communication device 20a further includes a laser pointer 80.

  The laser pointer 80 emits visible light along the optical axis direction of the light emitting unit 70. For this reason, the infrared transmission direction of the infrared communication device 20a can be visualized, and the user can easily aim at a device to be a communication partner. Therefore, it is possible to more reliably communicate with the target device. As will be described later, the laser pointer 80 is installed in the case 21 a in a state where it is mounted on one side of the printed circuit board 40.

  In the present embodiment, on the front surface 41 of the printed circuit board 40, an infrared receiving circuit 52 and an infrared transmitting circuit 54 that are part of the signal processing unit 50, and a light receiving unit 60 that is electrically connected to the infrared receiving circuit 52. And a light emitting unit 70 electrically connected to the infrared transmission circuit 54 is disposed. On the back surface 42 of the printed circuit board 40, a microcomputer 51, which is the remaining part of the signal processing unit 50, and a laser pointer 80 are arranged. In FIG. 10, for convenience, the infrared receiving circuit 52 is shown on the infrared transmitting circuit 54 and the light receiving unit 60 is shown on the light emitting unit 70, but actually, the infrared receiving circuit 52 and the light receiving unit 60 are Similar to the infrared transmission circuit 54 and the light emitting unit 70, it is mounted on the front surface 41 of the printed circuit board 40.

  In the case 21a, a communication interface unit 30, a printed circuit board 40, a signal processing unit 50, a light receiving unit 60, a light emitting unit 70, and a laser pointer 80 are installed. In the present embodiment, the case 21 a has a box shape extending in a longitudinal direction from the one end surface 22 toward the other end surface 23.

  The laser pointer 80, the signal processing unit 50, and the communication interface unit 30 are installed in order from the one end surface 22 to the other end surface 23 of the case 21a. Specifically, the laser pointer 80 is accommodated in the end portion 24 having the one end surface 22 among the longitudinal end portions 24 and 25 of the case 21a. The signal processing unit 50 is accommodated between both end portions 24 and 25 of the case 21a. The portion excluding the terminal 31 of the communication interface unit 30 is housed in the end portion 25 having the other end surface 23 among the longitudinal end portions 24 and 25 of the case 21a. The terminal 31 of the communication interface unit 30 protrudes from the other end surface 23 of the case 21a.

  In one end face 22 of the case 21a, an opening 61 and a transmission window 71 are formed, and a light transmission window 81 through which visible light from the laser pointer 80 passes is formed. Thus, since the transmission window 71 and the translucent window 81 are formed on the same surface of the case 21a, the infrared transmission direction of the infrared communication device 20a can be accurately visualized. Further, the laser pointer 80 is disposed at a position closer to the light emitting unit 70 than the light receiving unit 60. Since the transmission range of the light emitting unit 70 is narrowed, the control target can be reliably targeted.

  Regarding the configuration of the case 21a, the points other than the above are the same as the configuration of the case 21 of the infrared communication device 20 according to the first embodiment.

  As mentioned above, although embodiment of this invention was described, you may implement combining some of these embodiment. Alternatively, any one or some of these embodiments may be partially implemented. Specifically, any one of those described as “parts” in the description of these embodiments may be employed, or some arbitrary combinations may be employed.
