  The wireless remote controller 200 wirelessly transmits a setting signal for setting how the lighting control device 100a controls the lighting fixtures 300a to n, p (for example, dimming level) to the lighting control device 100a. In the illumination control device 100 a, the antenna 101 is, for example, an inverted F antenna or a chip antenna, receives a radio wave transmitted by the wireless remote controller 200, and inputs the received radio wave to the radio unit 103. The wireless unit 103 extracts a setting signal from the radio wave input from the antenna 101 and inputs the extracted setting signal to the control unit 104. The control unit 104 controls the state of the control unit 301 of one or more lighting fixtures 300 based on the setting signal input from the wireless unit 103 (for example, according to the dimming level indicated by the setting signal). Then, dimming control is performed on the lighting fixtures 300a to 300n, and the lighting fixtures 300a to 300n are blinked, turned on, and turned off).

The control unit 104 inputs sensor information from the human sensor 114 and outputs a signal to the wireless unit 103 in accordance with the input sensor information (for example, if the sensor information indicates the presence of a person, illumination A signal instructing lighting of the appliance 300p is output to the wireless unit 103). The radio | wireless part 103 inputs a signal from the control part 104, and transmits the input signal to the lighting fixture 300p via the antenna 101. FIG. On the other hand, the antenna 302 of the lighting fixture 300p receives the radio wave transmitted by the antenna 101 of the lighting control apparatus 100b, and inputs the received radio wave to the wireless unit 303.

Embodiment 1 FIG.
FIG. 2 is a diagram (perspective view) illustrating the configuration of the illumination control device 100.

  As described above, the illumination control device 100 includes the antenna 101 and the circuit board 102, and includes a substantially cylindrical (or other shape) housing 105 and a plurality of attachment springs 108. At least a part of the wall portion 106 of the housing 105 is formed of a dielectric material such as plastic. For example, when the lighting control device 100 is used by being inserted into a space behind the ceiling and fixed to the ceiling, the mounting spring 108 fixes the housing 105 to the opening of the ceiling using its own elastic force. To do. The attachment spring 108 may be omitted when the lighting control device 100 takes another form. In this embodiment mode, the antenna 101 is fixed on the circuit board 102, and the antenna 101 and the circuit board 102 constitute an integral part 107. The movable portion 107 is disposed inside the housing 105 so as to be displaceable using, for example, a slide mechanism (for example, a handle for sliding the movable portion 107 on the bottom of the housing 105 may be provided). Good). As shown in FIG. 1, the antenna 101 is connected to a radio unit 103 mounted on the circuit board 102, and the radio unit 103 transmits and receives signals such as setting signals via the antenna 101. And the control part 104 mounted on the circuit board 102 controls the lighting fixture 300 based on the signal which the radio | wireless part 103 transmitted / received.

  Depending on the environment of the installation location of the illumination control device 100, the radio unit 103 may not be able to extract part or all of the setting signal from the radio wave input from the antenna 101 because the electric field level of the antenna 101 is low. In this case, the wireless unit 103 cannot input a normal setting signal to the control unit 104, and the control unit 104 cannot control the luminaire 300. Or the control part 104 will control the lighting fixture 300 based on an incorrect setting. In this embodiment, the electric field level of the antenna 101 can be adjusted by displacing the movable portion 107 in such a case. That is, the electric field level of the antenna 101 is improved by displacing the movable portion 107 from a position where the electric field level of the antenna 101 is low (first position) to a position where the electric field level of the antenna 101 is high (second position). As a result, the wireless unit 103 can extract the setting signal from the radio wave input from the antenna 101 and input a normal setting signal to the control unit 104. In addition, in the present embodiment, the movable part 107 is provided in the illumination control apparatus 100 so that the antenna 101 can be displaced. Therefore, it is not necessary to disassemble the illumination control apparatus 100 in order to adjust the electric field level of the antenna 101. There is no need to remove it from the installation site. In addition, when installing the lighting control device 100, the movable unit 107 is set in advance, for example, when the lighting control device 100 is shipped from the wireless remote controller 200, for example, when the lighting control device 100 is shipped from the factory. The position of the antenna 101 can be moved to a position where the electric field level of the antenna 101 is higher (second position). At this time, in order to search for a position where the electric field level of the antenna 101 is higher, for example, the electric field level of the antenna 101 may be measured, or whether or not the setting from the wireless remote controller 200 can be normally performed is tested. Good.

  Further, depending on the environment of the installation location of the lighting control apparatus 100, interference may occur at a predetermined frequency used by the wireless unit 103 for signal transmission / reception, and communication quality may deteriorate (as described above, the antenna As in the case where the electric field level of 101 is low, the wireless unit 103 cannot extract part or all of the setting signal from the radio wave input from the antenna 101). In this case, it is desirable to change the frequency used by the wireless unit 103 to a frequency that does not cause interference. However, when the resonance point (resonance frequency) of the antenna 101 is different from the frequency after the change (for example, when the lighting control device 100 is shipped from the factory, it is desirable that the resonance point of the antenna 101 is optimized to a predetermined frequency. ), Even if the frequency is changed, the communication quality may not be improved. In this embodiment, the resonance point of the antenna 101 is adjusted by displacing the movable portion 107 so that the antenna 101 is brought close to (or away from) the wall portion 106 formed of a dielectric. It is possible. In other words, the position between the antenna 101 and the wall 106 is wide (or narrow) from the position (first position) to the position where the distance between the antenna 101 and the wall 106 is narrow (or wide) (second position). By displacing the unit 107, the resonance point of the antenna 101 can be changed, and as a result, the communication quality can be improved (the radio unit 103 extracts the setting signal from the radio wave input from the antenna 101). Thus, a normal setting signal can be input to the control unit 104).

  In this embodiment mode, it is only necessary that the position of the antenna 101 can be changed so that at least one of the electric field level and the resonance point of the antenna 101 can be adjusted. Therefore, the arrangement of the antenna 101 and the circuit board 102 and the direction in which the movable portion 107 can be displaced are not limited to those shown in FIG. For example, as shown in FIGS. 3 and 4, the movable portion 107 may be displaceable in any of the vertical, horizontal, and height directions of the circuit board 102, or may be displaceable in other directions. Good.

Embodiment 2. FIG.
In the following, the difference between the present embodiment and the first embodiment will be mainly described.

  FIG. 5 is a diagram (perspective view) showing the configuration of the illumination control device 100.

  In Embodiment 1, the antenna 101 is fixed on the circuit board 102, and the antenna 101 and the circuit board 102 are integrated to form the movable portion 107. On the other hand, in this embodiment mode, the antenna 101 is a part of an antenna substrate or an antenna unit, and is connected to the circuit substrate 102 by a signal line 109. The antenna substrate including the antenna 101 and the antenna unit constitute the movable portion 107. Similar to the first embodiment, the movable unit 107 is disposed inside the housing 105 so as to be displaceable using, for example, a slide mechanism.

  In this embodiment mode, as in Embodiment Mode 1, the electric field level of the antenna 101 can be adjusted by displacing the movable portion 107. That is, the electric field level of the antenna 101 is improved by displacing the movable portion 107 from a position where the electric field level of the antenna 101 is low (first position) to a position where the electric field level of the antenna 101 is high (second position). It becomes possible. In the present embodiment, similarly to the first embodiment, the movable portion 107 is displaced to bring the antenna 101 closer to (or away from) the wall portion 106 formed of a dielectric, so that the resonance of the antenna 101 is achieved. It is possible to adjust the points. In other words, the position between the antenna 101 and the wall 106 is wide (or narrow) from the position (first position) to the position where the distance between the antenna 101 and the wall 106 is narrow (or wide) (second position). By displacing the unit 107, the resonance point of the antenna 101 can be changed, and as a result, communication quality can be improved.

  In this embodiment, similarly to Embodiment 1, it is only necessary that the position of antenna 101 can be changed so that at least one of the electric field level of antenna 101 and the resonance point can be adjusted. Accordingly, the arrangement of the antenna 101, the antenna substrate or antenna unit that is the movable portion 107, the circuit board 102, and the direction in which the movable portion 107 can be displaced are not limited to those shown in FIG. For example, as shown in FIGS. 6 and 7, the antenna substrate or the antenna unit that is the movable portion 107 may be displaceable in any of the vertical, horizontal, and height directions, or in other directions. It may be.

Embodiment 3 FIG.
In the following, the difference between the present embodiment and the first and second embodiments will be mainly described.

In the present embodiment, the position at which the movable portion 107 can be displaced (the movable portion 107 has been displaced so that the movable portion 107 can only be displaced from the initial position (first position) to a predetermined position (second position)). (Restricted position) The first position is, for example, a position at the time of factory shipment of the lighting control device 100. Then, as shown in FIGS. 2 to 7, the second position is a position substantially Y away from the first position, and Y is set as follows. Here, a plurality of second positions may exist.
Y = λ / 2 × n
Y: The shortest distance from the position of the antenna 101 when the movable portion 107 is in the first position to the position of the antenna 101 when the movable portion 107 is in the second position (Y is shorter than the width of the housing 105) Suppose)
λ: wavelength at a predetermined frequency (the resonance point of the antenna 101 is adjusted to be the predetermined frequency when the antenna 101 is in the first position)
n: integer

  In the present embodiment, by restricting the position where the movable part 107 can be displaced as described above, only the resonance point of the antenna 101 is changed without changing the electric field level of the antenna 101 when the movable part 107 is displaced. It becomes easy to optimize.

Embodiment 4 FIG.
In the following, the difference between the present embodiment and the first and second embodiments will be mainly described.

In the present embodiment, the position where the movable portion 107 can be displaced is limited to a predetermined position. Here, the predetermined position is a position (second position) that is substantially Y away from the first position (for example, the factory-shipped position of the illumination control device 100) as shown in FIGS. , Y are set as follows. Here, a plurality of second positions may exist.
Y = λ / 4 + λ / 2 × n
Y: The shortest distance from the position of the antenna 101 when the movable portion 107 is in the first position to the position of the antenna 101 when the movable portion 107 is in the second position (Y is shorter than the width of the housing 105) Suppose)
λ: wavelength at a predetermined frequency (the resonance point of the antenna 101 is adjusted to be the predetermined frequency when the antenna 101 is in the first position)
n: integer

  In the present embodiment, by limiting the position where the movable part 107 can be displaced as described above, the electric field level of the antenna 101 is optimized when the movable part 107 is displaced (finding the maximum point of the electric field level). ) Becomes easy.

Embodiment 5 FIG.
In the following, the difference between the present embodiment and the first embodiment will be mainly described.

  FIG. 8 is a diagram (perspective view) showing the configuration of the illumination control device 100.

In the first embodiment, the electric field level of the antenna 101 is adjusted by displacing the movable portion 107. On the other hand, in this embodiment, the electric field level of the antenna 101 is adjusted by rotating the housing 105 itself. For this purpose, in the present embodiment, the casing 105 has a substantially cylindrical shape. Further, in this embodiment mode, the antenna 101 and the circuit board 102 are not configured as the movable portion 107 that can be displaced, and the position where the antenna 101 is disposed (first position) is determined from the central axis 110 of the housing 105. The position is substantially r away from the central axis 110 in the vertical direction, and r is set to a predetermined interval determined based on λ (λ: wavelength at a predetermined frequency). For example, r is set as follows.
r = Y / 2 (1)
Y = λ / 4 + λ / 2 × n
r: shortest distance from the center axis 110 of the housing 105 to the position of the antenna 101 (r is shorter than the radius of the bottom of the housing 105)
λ: wavelength at a predetermined frequency n: integer

  In this embodiment mode, by fixing the position where the antenna 101 is provided as described above, the electric field level of the antenna 101 can be easily adjusted only by rotating the housing 105. For example, when r is set as in (1) above, the housing 105 is rotated by approximately 180 degrees (at this time, the central axis 110 of the housing 105 becomes the rotation shaft 111), and the antenna 101 becomes the first Since the position is displaced to a position (second position) that is approximately Y away from the position, it is easy to optimize the electric field level of the antenna 101 (find the maximum point of the electric field level). When r is not set as in (1) above, the housing 105 is tilted at an angle other than 180 degrees so that the antenna 101 is displaced to a position (second position) substantially Y away from the first position. You may rotate with.

  That is, as long as the entire antenna 101 is disposed in the housing 105, the antenna 101 may be disposed at an arbitrary position where r is λ / 8 or more. For example, if the antenna 101 is disposed at a position λ / 8 away from the central axis 110 of the housing 105 (in this case, r = λ / 8), the housing 105 is rotated 180 degrees. The antenna 101 is displaced by λ / 4. Further, when the antenna 101 is disposed at an arbitrary position such that the distance between the position of the antenna 101 and the central axis 110 of the housing 105 is larger than λ / 8, the antenna is not rotated until the housing 105 is rotated 180 degrees. 101 is displaced by λ / 4, and the maximum point of the electric field level can be found. Thus, by arranging the position of the antenna 101 at a predetermined distance or more from the central axis 110, the antenna 101 can be easily moved to a position with a different electric field level simply by rotating the housing 105. Here, the antenna 101 when referring to the position of the antenna 101 is an arbitrary part of the antenna 101, and may be, for example, the center of the antenna 101 or the end of the antenna 101.

  In the present embodiment, it is only necessary that the position where the antenna 101 is disposed can be fixed as described above. Therefore, the directions of the antenna 101 and the circuit board 102 are not limited to those shown in FIG. For example, as shown in FIG. 9, the antenna 101 and the circuit board 102 may be arranged, or may be arranged in other directions. For example, as shown in FIG. 10, the antenna 101 may be a part of an antenna substrate or an antenna unit, and this may be connected to the circuit substrate 102 by a signal line 109.

  In the present embodiment, since the bottom portion of the housing 105 is formed in a circular shape, even if the housing 105 is rotated after the lighting control device 100 is installed, there is no sense of incongruity when viewed from below (aesthetics and This will not affect the ease of maintenance.) In addition, even when a status display LED or the like is provided at the bottom of the housing 105, the position of the LED or the like does not change significantly due to the rotation of the housing 105, so that the user feels uncomfortable when viewed from below. No (not affecting the aesthetics and visibility of LEDs).

  A handle for rotating the housing 105 may be provided at the bottom of the housing 105. By providing a handle on the bottom of the housing 105, the rotation operation of the housing 105 can be facilitated. The shape and size of the handle may be any as long as the user can easily rotate the housing 105. The handle may be provided integrally with the bottom of the housing 105 or may be provided separately from the bottom of the housing 105. In addition, in the case of another body, it can be set as the structure which can be removed. If the handle is separated, it can be attached only when rotating the casing 105 and can be removed during normal use, so there is no sense of incongruity even when the bottom of the casing 105 is viewed from below (the aesthetics are improved) To do). Note that when sensors such as the human sensor 114 and the illuminance sensor 115 are provided inside the housing 105, a part of the sensor is exposed from the bottom of the housing 105. Is formed in a circular shape, the exposed portion is not unnaturally arranged.

  When a power supply line for supplying power to the illumination control device 100 is drawn into the housing 105, it is desirable to provide a power supply line lead-in port on the top of the housing 105. By providing the power line lead-in port on the upper portion of the housing 105, the power wire is not forcibly pulled when the housing 105 is rotated.

Embodiment 6 FIG.
In the following, the difference between the present embodiment and the first embodiment will be mainly described.

  FIG. 11 is a diagram (perspective view) illustrating the configuration of the illumination control apparatus 100.

  In the first embodiment, the antenna 101 and the circuit board 102 are integrated to form the movable portion 107. On the other hand, in this embodiment mode, the dielectric 112 constitutes the movable portion 107 separately from the antenna 101 and the circuit board 102. Similar to the first embodiment, the movable unit 107 is disposed inside the housing 105 so as to be displaceable using, for example, a slide mechanism.

  In this embodiment mode, the resonance point of the antenna 101 can be adjusted by displacing the movable portion 107 so that the dielectric 112 that is the movable portion 107 is brought close to (or away from) the antenna 101. That is, the position between the antenna 101 and the dielectric 112 is wide (or narrow) from the position (first position) to the position where the distance between the antenna 101 and the dielectric 112 is narrow (or wide) (second position). The resonance point of the antenna 101 can be changed by displacing the dielectric 112 serving as the unit 107, and as a result, communication quality can be improved.

  In the present embodiment, it is sufficient that the position of the dielectric 112 can be changed so that the resonance point of the antenna 101 can be adjusted. Therefore, the arrangement of the antenna 101 and the circuit board 102 and the direction in which the movable portion 107 can be displaced are not limited to those shown in FIG. For example, as shown in FIG. 12, the dielectric 112 as the movable portion 107 may be displaceable in any of the vertical, horizontal, and height directions of the circuit board 102, and may be displaceable in other directions. May be.

  In this embodiment, the resonance point of the antenna 101 is adjusted by displacing the movable portion 107 using the dielectric 112 as the movable portion 107. However, the antenna 101 (or the antenna 101 and the circuit board 102 are integrated with each other). The same effect can be obtained even if the movable portion 107 is displaced using the movable portion 107 as the movable portion 107. At this time, the dielectric 112 may be fixed inside the housing 105 or may be displaceable.

Embodiment 7 FIG.
In the following, the difference between the present embodiment and the first and second embodiments will be mainly described.

  FIG. 13 is a diagram (perspective view) illustrating the configuration of the illumination control device 100.

In the first embodiment, the electric field level and the resonance point of the antenna 101 are adjusted by linearly displacing the movable portion 107 using, for example, a slide mechanism. On the other hand, in the present embodiment, a rotating unit 113 (rotating mechanism) that supports the movable unit 107 and can rotate the movable unit 107 is provided inside the housing 105. Then, the electric field level and resonance point of the antenna 101 are adjusted by rotating the rotating unit 113 and displacing the movable unit 107. Further, in the present embodiment, the movable portion 107 is arranged so that the distance between the antenna 101 and the rotation shaft 111 of the rotation portion 113 is substantially r in the vertical direction of the rotation shaft 111, and r is λ (λ: a predetermined frequency) Set to a predetermined interval determined based on the wavelength at (1). For example, r is set as follows.
r = Y / 2
Y = λ / 2 × n
r: The shortest distance from the rotation axis 111 of the rotating unit 113 to the position of the antenna 101 (r is shorter than the radius of the bottom of the housing 105)
λ: wavelength at a predetermined frequency n: integer

  In the present embodiment, as shown in FIG. 13, the rotating unit 113 is further installed so that the rotating shaft 111 of the rotating unit 113 does not overlap the central axis of the housing 105. Therefore, when the rotating unit 113 is rotated approximately 180 degrees, the distance between the antenna 101 and the wall 106 from the position where the distance between the antenna 101 and the wall 106 becomes a (first position) is b (where a The movable portion 107 can be displaced to a position (second position) that becomes <b), and the resonance point of the antenna 101 can be changed.

  In the present embodiment, by setting the distance between the antenna 101 and the rotating shaft 111 of the rotating unit 113 and the position of the rotating shaft 111 of the rotating unit 113 as described above, the rotating unit 113 is rotated approximately 180 degrees. The antenna 101 is displaced to a second position that is approximately Y (Y = λ / 2 × n) away from the first position, and the distance between the antenna 101 and the wall portion 106 formed of a dielectric is changed. Therefore, it becomes easy to optimize only the resonance point of the antenna 101 without changing the electric field level of the antenna 101.

The r may be set as follows.
r = Y / 2
Y = λ / 4 + λ / 2 × n
r: The shortest distance from the rotation axis 111 of the rotating unit 113 to the position of the antenna 101 (r is shorter than the radius of the bottom of the housing 105)
λ: wavelength at a predetermined frequency n: integer

  In the present embodiment, by setting the distance between the antenna 101 and the rotating shaft 111 of the rotating unit 113 and the position of the rotating shaft 111 of the rotating unit 113 as described above, the rotating unit 113 is rotated approximately 180 degrees. The antenna 101 is displaced to a second position that is approximately Y (Y = λ / 4 + λ / 2 × n) away from the first position, and the distance between the antenna 101 and the wall portion 106 formed of a dielectric is increased. Since it is changed, it becomes easy to simultaneously optimize the electric field level of the antenna 101 and the resonance point.

  In this embodiment mode, the orientation of the antenna 101 and the circuit board 102 is not limited to that shown in FIG. Further, for example, as shown in FIG. 14, the antenna 101 may be a part of an antenna substrate or an antenna unit, and this may be connected to the circuit substrate 102 by a signal line 109.
