[Lighting device]
First, the lighting device 10 will be described. The illumination device 10 is a so-called ambient illumination that illuminates a room, and is disposed, for example, on a ceiling 40. The lighting device 10 illuminates at least one of a ceiling 40 (ceiling surface) and a wall 50 (wall surface). The lighting device 10 may illuminate the floor 60 (floor surface). Specifically, the lighting device 10 emits light at a brightness according to the dimming signal received from the sensor device 30. That is, the lighting device 10 is light-controlled by the sensor device 30.
 なお、照明装置10の態様は、図1に示されるような平面視形状が円形のシーリングライトに限定されるものではなく、直管LEDランプを有するベースライトなどの長尺状の照明装置であってもよいし、ダウンライト等であってもよい。実施の形態1では、照明システム100は、1つの照明装置10を備えるが、複数の照明装置10を備えてもよい。図2に示されるように、照明装置10は、第一受信部11と、調光回路12と、発光部13とを備える。 In addition, the aspect of the illuminating device 10 is not limited to a ceiling light whose planar view shape is circular as shown by FIG. 1, and is a long-shaped illuminating device, such as a base light which has a straight tube LED lamp.

 [窓装置]
 窓装置20は、壁50に配置され、天井40、壁50、及び床60によって囲まれた空間の外部から当該空間に光(可視光)を取り入れるための装置である。窓装置20は、いわゆるスマートウィンドウであり、光の透過率の制御が可能である。図2に示されるように、窓装置20は、第二受信部21と、デバイス制御部22と、光学デバイス23と、第二記憶部24とを備える。
[Window device]
The window device 20 is disposed on the wall 50 and is a device for introducing light (visible light) into the space from the outside of the space surrounded by the ceiling 40, the wall 50, and the floor 60. The window device 20 is a so-called smart window, and can control light transmittance. As shown in FIG. 2, the window device 20 includes a second reception unit 21, a device control unit 22, an optical device 23, and a second storage unit 24.
 第二受信部21は、センサ装置30が備える送信部33から制御信号を受信する。第二受信部21は、例えば、通信回路(通信モジュール)であり、センサ装置30が備える送信部33から有線通信によって制御信号を受信する。なお、第二受信部21は、無線通信により制御信号を受信してもよい。また、デバイス制御部22が制御信号を直接受信するような場合、第二受信部21は、デバイス制御部22の一部として、デバイス制御部22に含まれる。 The second receiver 21 receives a control signal from the transmitter 33 included in the sensor device 30. The second receiver 21 is, for example, a communication circuit (communication module), and receives a control signal from the transmitter 33 included in the sensor device 30 by wired communication. The second reception unit 21 may receive the control signal by wireless communication. When the device control unit 22 directly receives the control signal, the second reception unit 21 is included in the device control unit 22 as a part of the device control unit 22.
 デバイス制御部22は、光学デバイス23に印加する電圧を制御することにより、光学デバイス23の光の透過率を変更する。デバイス制御部22は、具体的には、プロセッサ、マイクロコンピュータ、または専用回路などにより実現されるが、これらの組み合わせによって実現されてもよい。 The device control unit 22 changes the light transmittance of the optical device 23 by controlling a voltage applied to the optical device 23. The device control unit 22 is specifically realized by a processor, a microcomputer, a dedicated circuit, or the like, but may be realized by a combination of these.
 光学デバイス23は、窓枠、及び、窓枠に嵌めこまれた透光性を有する板材からなり、デバイス制御部22によって印加される電圧に応じて光の透過率の変更が可能なデバイスである。光学デバイス23を構成する上記板材は、2枚の透明の板と、2枚の透明の板の間に配置された2つの透明電極板と、2つの透明電極板の間に配置された液晶層とを有する。 The optical device 23 is made of a window frame and a translucent plate fitted in the window frame, and is a device capable of changing the light transmittance according to the voltage applied by the device control unit 22. . The plate material constituting the optical device 23 has two transparent plates, two transparent electrode plates disposed between the two transparent plates, and a liquid crystal layer disposed between the two transparent electrode plates.
 デバイス制御部22によって2つの透明電極板の間に電圧が印加されている間は、液晶層に含まれる液晶分子が整列するため、光学デバイス23の光の透過率は向上する。一方で、デバイス制御部22によって2つの電極層の間に電圧が印加されていない間は、液晶層に含まれる液晶分子が不規則に並ぶため、光学デバイス23の光の透過率は低下する。なお、光学デバイス23は、液晶層(液晶)に代えて、調光フィルム、エレクトロクロミック素子、またはSPD(Suspended Particle Device)などが使用されたデバイスであってもよい。 Since the liquid crystal molecules contained in the liquid crystal layer are aligned while the voltage is applied between the two transparent electrode plates by the device control unit 22, the light transmittance of the optical device 23 is improved. On the other hand, while the voltage is not applied between the two electrode layers by the device control unit 22, the liquid crystal molecules contained in the liquid crystal layer are irregularly arranged, and the light transmittance of the optical device 23 is lowered. The optical device 23 may be a device using a light control film, an electrochromic element, a SPD (Suspended Particle Device), or the like instead of the liquid crystal layer (liquid crystal).
 第二記憶部24は、デバイス制御部22がプロセッサなどによって実現される場合に、デバイス制御部22によって実行されるプログラムが記憶される記憶装置である。第二記憶部24は、具体的には、半導体メモリなどによって実現される。 The second storage unit 24 is a storage device in which a program executed by the device control unit 22 is stored when the device control unit 22 is realized by a processor or the like. Specifically, the second storage unit 24 is realized by a semiconductor memory or the like.
 なお、光学デバイス23が可視光帯域の屈折率を変更可能な屈折率可変材料を含むなどにより、光の配光角を制御できるデバイスである場合、窓装置20は、光の配光角を制御してもよい。具体的には、窓装置20が備えるデバイス制御部22は、光学デバイス23に印加する電圧を制御することにより、光学デバイス23の配光角を変更してもよい。窓装置20は、光の透過率及び光の配光角の少なくとも一方を制御できればよい。 When the optical device 23 is a device capable of controlling the light distribution angle of light, such as by including a refractive index variable material capable of changing the refractive index in the visible light band, the window device 20 controls the light distribution angle of light. You may Specifically, the device control unit 22 included in the window device 20 may change the light distribution angle of the optical device 23 by controlling the voltage applied to the optical device 23. The window device 20 may control at least one of the light transmittance and the light distribution angle.

 センサ装置30は、天井40及び壁50の少なくとも一方の明るさを検知し、検知された明るさに応じた調光信号を照明装置10に送信することにより、照明装置10を調光制御する装置である。センサ装置30は、照明装置10とは別体の装置であり、センサ装置30自体は、照明機能を有しない。センサ装置30は、例えば、天井40に配置されるが、壁50に配置されてもよい。センサ装置30は、一部が天井40及び壁50のいずれかの構造物内に配置される(位置する)が、全部が構造物内に配置されてもよい。センサ装置30は、天井40及び壁50のいずれかの構造物に外付けされてもよい。 The sensor device 30 detects lightness of at least one of the ceiling 40 and the wall 50, and transmits a light adjustment signal according to the detected lightness to the lighting device 10, thereby performing light adjustment control of the lighting device 10. It is. The sensor device 30 is a device separate from the lighting device 10, and the sensor device 30 itself does not have a lighting function. The sensor device 30 is disposed, for example, on the ceiling 40, but may be disposed on the wall 50. Although the sensor device 30 is partially disposed (located) in the structure of either the ceiling 40 or the wall 50, the sensor device 30 may be entirely disposed in the structure. The sensor device 30 may be externally attached to any of the ceiling 40 and wall 50 structures.
 図2及び図3に示されるように、センサ装置30は、具体的には、検知部31と、制御部32と、送信部33と、第一記憶部38とを備える。なお、内部筐体34と、外郭筐体35と、光拡散材36と、ケーブル37とは、図3に図示されている。 As shown in FIGS. 2 and 3, specifically, the sensor device 30 includes a detection unit 31, a control unit 32, a transmission unit 33, and a first storage unit 38. The inner casing 34, the outer casing 35, the light diffusing material 36, and the cable 37 are illustrated in FIG.
 検知部31は、天井40及び壁50のいずれかの構造物に配置され、天井40及び壁50の少なくとも一方の明るさを検知する。検知部31は、具体的には、光電変換素子31aと、フィルタ31bとを有する。また、検知部31は、受光面31cを有する。 The detection unit 31 is disposed in any structure of the ceiling 40 and the wall 50, and detects the brightness of at least one of the ceiling 40 and the wall 50. Specifically, the detection unit 31 includes a photoelectric conversion element 31 a and a filter 31 b. The detection unit 31 also has a light receiving surface 31c.
 光電変換素子31aは、光電変換素子31aの受光面に入る光を電気信号に変換して出力する。光電変換素子31aは、例えば、フォトダイオードである。光電変換素子31aは、受光面が下方(床60側)を向いた状態で、光電変換素子31aの一部が天井40に埋め込まれるように配置される。光電変換素子31aの受光面(検知部31の受光面31c)は、センサ装置30が配置される天井40及び壁50のいずれかの構造物(検知対象の構造物)とは反対側に位置する。 The photoelectric conversion element 31a converts light entering the light receiving surface of the photoelectric conversion element 31a into an electric signal and outputs the electric signal. The photoelectric conversion element 31a is, for example, a photodiode. The photoelectric conversion element 31 a is disposed such that a part of the photoelectric conversion element 31 a is embedded in the ceiling 40 with the light receiving surface facing downward (floor 60 side). The light receiving surface (the light receiving surface 31c of the detection unit 31) of the photoelectric conversion element 31a is located on the opposite side to the structure (structure to be detected) of either the ceiling 40 or the wall 50 on which the sensor device 30 is disposed. .
 フィルタ31bは、光電変換素子31aの受光面を覆うフィルタである。フィルタ31bは、光電変換素子31aの分光感度特性を人間の視感度に近づける、いわゆる視感度フィルタである。なお、フィルタ31bは、必須ではなく、省略されてもよい。 The filter 31 b is a filter that covers the light receiving surface of the photoelectric conversion element 31 a. The filter 31 b is a so-called visual sensitivity filter that brings the spectral sensitivity characteristic of the photoelectric conversion element 31 a close to human visual sensitivity. The filter 31 b is not essential, and may be omitted.
 制御部32は、照明装置10を、検知部31によって検知された明るさに応じて調光するための調光信号を生成する。制御部32は、具体的には、検知部31によって検知された明るさと所定の明るさとを比較し、検知された明るさが所定の明るさよりも明るい場合には、照明装置10を現在よりも暗く発光させる調光信号を生成する。制御部32は、検知された明るさが所定の明るさよりも暗い場合には、照明装置10を現在よりも明るく発光させる調光信号を生成する。これにより、検知部31によって検知される明るさが所定の明るさに近づく制御が実現される。 The control unit 32 generates a light adjustment signal for adjusting the lighting device 10 in accordance with the brightness detected by the detection unit 31. Specifically, the control unit 32 compares the brightness detected by the detection unit 31 with a predetermined brightness, and when the detected brightness is brighter than the predetermined brightness, the lighting device 10 is compared with the current one. A dimming signal to emit light in dark is generated. When the detected brightness is darker than a predetermined brightness, the control unit 32 generates a light control signal that causes the lighting device 10 to emit light brighter than the present. Thus, control is realized in which the brightness detected by the detection unit 31 approaches the predetermined brightness.
 また、制御部32は、窓装置20の透過率または配光角を制御するための制御信号を、検知部31によって検知された明るさに基づいて生成してもよい。制御信号の生成は、上記調光信号の生成に代えて行われてもよいし、上記調光信号の生成に加えて行われてもよい。 Further, the control unit 32 may generate a control signal for controlling the transmittance or the light distribution angle of the window device 20 based on the brightness detected by the detection unit 31. The generation of the control signal may be performed instead of the generation of the dimming signal or may be performed in addition to the generation of the dimming signal.
 この場合、制御部32は、例えば、検知部31によって検知された明るさが所定の明るさよりも明るい場合には、光学デバイス23への電圧印加をオフする(透過率を低下させる)ための制御信号を生成する。また、制御部32は、検知された明るさが所定の明るさよりも暗い場合には、光学デバイス23への電圧印加をオンする(透過率を向上する)ための制御信号を生成する。これにより、照明装置10をさらに明るく発光させずに、外光によって空間の明るさを所定の明るさに近づけることができる。つまり、外光を積極的に採光することにより消費電力の低減を実現することができる。 In this case, for example, when the brightness detected by the detection unit 31 is brighter than the predetermined brightness, the control unit 32 performs control to turn off the voltage application to the optical device 23 (decrease the transmittance). Generate a signal. In addition, when the detected brightness is darker than the predetermined brightness, the control unit 32 generates a control signal for turning on the voltage application to the optical device 23 (i.e., to improve the transmittance). As a result, the brightness of the space can be brought close to the predetermined brightness by the outside light without causing the lighting device 10 to emit light brighter. In other words, reduction of power consumption can be realized by positively lighting the outside light.
 制御部32は、具体的には、プロセッサ、マイクロコンピュータ、または専用回路などにより実現されるが、これらの組み合わせによって実現されてもよい。 The control unit 32 is specifically realized by a processor, a microcomputer, a dedicated circuit, or the like, but may be realized by a combination of these.
 送信部33は、制御部32によって生成された調光信号を照明装置10に送信する。また、送信部33は、制御部32によって生成された制御信号を窓装置20に送信する。送信部33は、具体的には、通信回路(通信モジュール)であり、有線通信によって調光信号を送信する。なお、送信部33は、無線通信により調光信号を送信してもよい。また、制御部32が調光信号及び制御信号を照明装置に直接送信するような場合、送信部33は、制御部32の一部として、制御部32に含まれる。 The transmitter 33 transmits the dimming signal generated by the controller 32 to the lighting device 10. In addition, the transmission unit 33 transmits the control signal generated by the control unit 32 to the window device 20. Specifically, the transmission unit 33 is a communication circuit (communication module), and transmits a dimming signal by wired communication. The transmitter 33 may transmit the dimming signal by wireless communication. In addition, when the control unit 32 directly transmits the dimming signal and the control signal to the lighting device, the transmission unit 33 is included in the control unit 32 as a part of the control unit 32.
 内部筐体34は、制御部32及び送信部33を収容する筐体である。内部筐体34は、例えば、有底円筒状である。内部筐体34は、樹脂によって形成されてもよいし、金属によって形成されてもよい。 The internal housing 34 is a housing that accommodates the control unit 32 and the transmission unit 33. The inner housing 34 is, for example, a bottomed cylindrical shape. The inner housing 34 may be made of resin or metal.
 外郭筐体35は、内部筐体34を収容する筐体である。外郭筐体35は、天井40に埋め込まれ、内部に内部筐体34が配置される小径部と、小径部よりも下方に位置し、小径部よりも径が大きい大径部とを含む。大径部は、天井40よりも下方(つまり、空間内)に位置し、側面に複数の第一開口部35bが配置される。第一開口部35bは、少なくとも1つ配置されればよい。外郭筐体35は、樹脂によって形成されてもよいし、金属によって形成されてもよい。外郭筐体35の底板の部分は、カバー部材35aである。 The outer casing 35 is a casing that accommodates the inner casing 34. Outer shell 35 is embedded in ceiling 40 and includes a small diameter portion in which inner housing 34 is disposed, and a large diameter portion positioned below the small diameter portion and having a larger diameter than the small diameter portion. The large diameter portion is located below the ceiling 40 (that is, in the space), and the plurality of first openings 35 b are disposed on the side surface. At least one first opening 35 b may be disposed. The outer casing 35 may be made of resin or metal. The bottom plate portion of the outer casing 35 is a cover member 35a.
 カバー部材35aは、検知部31の受光面31cと対向配置される円板状の部材である。カバー部材35aは、光(可視光)の遮蔽部材であり、例えば、遮光性を有する材料または透光性を有しない材料により形成される。カバー部材35aは、天井40との間に第一開口部35bを形成する。 The cover member 35 a is a disk-shaped member disposed to face the light receiving surface 31 c of the detection unit 31. The cover member 35 a is a light (visible light) shielding member, and is formed of, for example, a light shielding material or a non-light transmitting material. The cover member 35 a forms a first opening 35 b with the ceiling 40.
 カバー部材35aは、検知部31の検知範囲の一部を遮る。この結果、検知部31の検知範囲は、図3に破線で示されるような検知範囲となる。そうすると、検知部31は、天井40とカバー部材35aとの間の第一開口部35bから入る光を検知する。言い換えれば、検知部31は、第一開口部35bを通って受光面31cに入る光の明るさを、天井40及び壁50の少なくとも一方の明るさとして検知することができる。検知範囲は、カバー部材35aの大きさによって調整することができる。 The cover member 35 a blocks part of the detection range of the detection unit 31. As a result, the detection range of the detection unit 31 is a detection range as indicated by a broken line in FIG. Then, the detection unit 31 detects light entering from the first opening 35 b between the ceiling 40 and the cover member 35 a. In other words, the detection unit 31 can detect the brightness of light entering the light receiving surface 31 c through the first opening 35 b as the brightness of at least one of the ceiling 40 and the wall 50. The detection range can be adjusted by the size of the cover member 35a.
 なお、検知部31は、第一開口部35bを通って直接検知部31に入る光だけでなく、カバー部材35aの上面によって反射された光も検知する。特に、天井40の明るさは、主として天井40に当たった光がカバー部材35aの上面で反射されて検知部31に入ることで検知される。そこで、カバー部材35aに当たる光を有効に利用するために、カバー部材35aの検知部31の受光面31c(フィルタ31b)と対向する面に、光拡散材36が配置されるとよい。 The detection unit 31 detects not only the light entering the detection unit 31 directly through the first opening 35 b but also the light reflected by the upper surface of the cover member 35 a. In particular, the brightness of the ceiling 40 is detected mainly by the light striking the ceiling 40 being reflected by the upper surface of the cover member 35 a and entering the detection unit 31. Therefore, in order to effectively use the light falling on the cover member 35a, the light diffusion material 36 may be disposed on the surface facing the light receiving surface 31c (filter 31b) of the detection unit 31 of the cover member 35a.
 光拡散材36は、第一開口部35bを通って当該光拡散材36に入った光を拡散する。光拡散材36は、シート状の部材であってもよいし、塗料であってもよい。光拡散材36は、具体的には、シリカや炭酸カルシウム等の光拡散材(微粒子)を含有する、樹脂または白色顔料などによって形成される。なお、光拡散材36に代えて、カバー部材35a自体が光拡散性を有してもよい。例えば、カバー部材35aの検知部31と対向する面が光を拡散するための凹凸構造を有してもよい。 The light diffusion material 36 diffuses the light that has entered the light diffusion material 36 through the first opening 35 b. The light diffusion material 36 may be a sheet-like member, or may be a paint. Specifically, the light diffusion material 36 is formed of a resin, a white pigment, or the like containing a light diffusion material (fine particles) such as silica or calcium carbonate. Note that, instead of the light diffusion material 36, the cover member 35a itself may have light diffusibility. For example, the surface of the cover member 35 a facing the detection unit 31 may have a concavo-convex structure for diffusing light.
 ケーブル37は、送信部33によって送信される調光信号及び制御信号を伝送するための信号線である。詳細については図示されないが、ケーブル37の一端は、送信部33に電気的に接続され、ケーブル37の他端は、照明装置10が備える第一受信部11または窓装置20が備える第二受信部21に電気的に接続される。なお、図示されないが、センサ装置30は、電力系統からセンサ装置30に電力を供給するための電源線と、電源線から供給される交流電力をセンサ装置30の動作に適した直流電力に変換する電源回路とを備えてもよい。 The cable 37 is a signal line for transmitting the dimming signal and the control signal transmitted by the transmission unit 33. Although not shown in detail, one end of the cable 37 is electrically connected to the transmitter 33, and the other end of the cable 37 is the first receiver 11 included in the lighting device 10 or the second receiver included in the window device 20. 21 is electrically connected. Although not shown, the sensor device 30 converts the AC power supplied from the power supply line for supplying power to the sensor device 30 from the power system to the DC power suitable for the operation of the sensor device 30. And a power supply circuit.
 第一記憶部38は、制御部32がプロセッサなどによって実現される場合に、制御部32によって実行されるプログラムが記憶される記憶装置である。第一記憶部38は、具体的には、半導体メモリなどによって実現される。 The first storage unit 38 is a storage device in which a program executed by the control unit 32 is stored when the control unit 32 is realized by a processor or the like. Specifically, the first storage unit 38 is realized by a semiconductor memory or the like.
 [実施の形態1の効果等]
 以上説明したセンサ装置30は、天井40及び壁50のいずれかの構造物に配置される。センサ装置30は、天井40及び壁50の少なくとも一方の明るさを検知する検知部31と、天井40及び壁50の少なくとも一方を照明する照明装置10を、検知された明るさに応じて調光するための調光信号を生成する制御部32と、生成された調光信号を照明装置10に送信する送信部33とを備える。
[Effects of Embodiment 1]
The sensor device 30 described above is disposed in any structure of the ceiling 40 and the wall 50. The sensor device 30 dims the detection unit 31 that detects the brightness of at least one of the ceiling 40 and the wall 50 and the lighting device 10 that illuminates at least one of the ceiling 40 and the wall 50 according to the detected brightness. And a transmission unit 33 that transmits the generated light adjustment signal to the lighting apparatus 10.
 これにより、センサ装置30は、天井40及び壁50の少なくとも一方の明るさに応じて照明装置10を調光することができる。つまり、センサ装置30は、照明装置10を床60以外の明るさに基づいて調光することができる。 Thus, the sensor device 30 can dim the lighting device 10 according to the brightness of at least one of the ceiling 40 and the wall 50. That is, the sensor device 30 can dim the lighting device 10 based on the brightness other than the floor 60.
 また、センサ装置30は、検知部31は、受光面31cを有し、センサ装置30は、さらに、受光面31cと対向配置され、天井40及び壁50のいずれかの構造物との間に第一開口部35bを形成するカバー部材35aを備えてもよい。検知部31は、第一開口部35bを通って検知部31に入る光の明るさを、天井40及び壁50の少なくとも一方の明るさとして検知してもよい。 Further, the sensor unit 30 has a light receiving surface 31 c, and the sensor unit 30 is further disposed to face the light receiving surface 31 c, and the sensor unit 30 is disposed between the ceiling 40 and any structure of the wall 50. You may provide the cover member 35a which forms the one opening part 35b. The detection unit 31 may detect the brightness of light entering the detection unit 31 through the first opening 35 b as the brightness of at least one of the ceiling 40 and the wall 50.
 このようなカバー部材35aにより、検知部31は、床60の明るさを検知対象から除くことができる。つまり、検知部31は、床60の明るさ、並びに、天井40及び壁50の少なくとも一方の明るさのうち、天井40及び壁50の少なくとも一方の明るさを選択的に検知することができる。 The detection unit 31 can remove the brightness of the floor 60 from the detection target by such a cover member 35 a. That is, the detection unit 31 can selectively detect the brightness of at least one of the ceiling 40 and the wall 50 among the brightness of the floor 60 and the brightness of at least one of the ceiling 40 and the wall 50.
 また、カバー部材35aの受光面31cと対向する面には、光拡散材36が配置されていてもよい。 The light diffusing material 36 may be disposed on the surface of the cover member 35 a facing the light receiving surface 31 c.
 これにより、検知部31は、光拡散材36による光の拡散を利用して、天井40及び壁50の少なくとも一方の明るさを検知することができる。 Thus, the detection unit 31 can detect the brightness of at least one of the ceiling 40 and the wall 50 by using the diffusion of light by the light diffusion material 36.
 また、制御部32は、さらに、天井40及び壁50によって囲まれた空間の外部から当該空間に光を取り入れるための窓装置20であって光の透過率の制御が可能な窓装置20の、光の透過率を制御するための制御信号を、検知された明るさに基づいて生成してもよい。送信部33は、さらに、生成された制御信号を窓装置20に送信してもよい。 In addition, the control unit 32 is a window device 20 for introducing light into the space from the outside of the space surrounded by the ceiling 40 and the wall 50, and of the window device 20 capable of controlling the light transmittance, A control signal for controlling light transmittance may be generated based on the detected brightness. The transmission unit 33 may further transmit the generated control signal to the window device 20.
 これにより、センサ装置30は、天井40及び壁50の少なくとも一方の明るさに応じて窓装置20の光の透過率を制御することができる。 Thus, the sensor device 30 can control the light transmittance of the window device 20 according to the brightness of at least one of the ceiling 40 and the wall 50.
 また、制御部32は、さらに、天井40及び壁50によって囲まれた空間の外部から当該空間に光を取り入れるための窓装置20であって光の配光角の制御が可能な窓装置20の、光の配光角を制御するための制御信号を、検知された明るさに基づいて生成してもよい。送信部33は、さらに、生成された制御信号を窓装置20に送信してもよい。 Further, the control unit 32 is a window device 20 for introducing light into the space from the outside of the space surrounded by the ceiling 40 and the wall 50, and the window device 20 capable of controlling the light distribution angle of the light. The control signal for controlling the light distribution angle of light may be generated based on the detected brightness. The transmission unit 33 may further transmit the generated control signal to the window device 20.
 これにより、センサ装置30は、天井40及び壁50の少なくとも一方の明るさに応じて窓装置20の光の配光角を制御することができる。 Thereby, the sensor device 30 can control the light distribution angle of the light of the window device 20 according to the brightness of at least one of the ceiling 40 and the wall 50.
 [実施の形態1の変形例]
 センサ装置30においては、第一開口部35bの大きさは固定であったが、センサ装置30は、例えば、第一開口部35bの大きさを調整するための調整機構を備えてもよい。図4及び図5は、第一開口部35bの大きさを調整するための調整機構を上方から見た斜視図である。
[Modification of Embodiment 1]
Although the size of the first opening 35 b is fixed in the sensor device 30, the sensor device 30 may include, for example, an adjustment mechanism for adjusting the size of the first opening 35 b. FIG.4 and FIG.5 is the perspective view which looked at the adjustment mechanism for adjusting the magnitude | size of the 1st opening 35b from upper direction.
 図4及び図5に示される調整機構70は、上述した外郭筐体35の大径部に相当し、第一筐体71、及び、第一筐体71を外側から囲む第二筐体72の二重構造を有する。第一筐体71及び第二筐体72は、いずれも有底円筒状であり、筒軸が一致するように配置されている。第一筐体71及び第二筐体72は、いずれも側面に複数の開口部が設けられている。第一筐体71及び第二筐体72のそれぞれにおいて、複数の開口部は、円周方向に並んで配置される。 The adjustment mechanism 70 shown in FIGS. 4 and 5 corresponds to the large diameter portion of the outer casing 35 described above, and the first casing 71 and a second casing 72 surrounding the first casing 71 from the outside. It has a double structure. Each of the first housing 71 and the second housing 72 has a bottomed cylindrical shape, and is disposed such that the cylinder axes coincide with each other. Each of the first housing 71 and the second housing 72 is provided with a plurality of openings on the side surface. In each of the first housing 71 and the second housing 72, the plurality of openings are arranged side by side in the circumferential direction.
 第一筐体71の側面に設けられた開口部と、第二筐体72の側面に設けられた開口部とは、側方から見て重なるように配置されている。第一筐体71の側面に設けられた開口部と、第二筐体72の側面に設けられた開口部との重なりによって形成される第一開口部73の大きさ(開口面積)は、第一筐体71に対して第二筐体72を筒軸回りに回動させることにより調整される。例えば、図4に示される状態で第二筐体72を第一筐体71に対して下方から見て時計回りに回動させると、図5に示されるように、第一開口部73の大きさは小さくなる。 The opening provided on the side surface of the first housing 71 and the opening provided on the side surface of the second housing 72 are arranged so as to overlap with each other as viewed from the side. The size (opening area) of the first opening 73 formed by overlapping the opening provided on the side surface of the first housing 71 and the opening provided on the side surface of the second housing 72 The adjustment is made by rotating the second housing 72 around the cylinder axis with respect to the one housing 71. For example, when the second housing 72 is rotated clockwise as viewed from below with respect to the first housing 71 in the state shown in FIG. 4, the size of the first opening 73 is obtained as shown in FIG. 5. Becomes smaller.
 このように、センサ装置30は、さらに、第一開口部35bの開口面積を調整するための調整機構(例えば、調整機構70)を備えてもよい。 Thus, the sensor device 30 may further include an adjustment mechanism (for example, the adjustment mechanism 70) for adjusting the opening area of the first opening 35b.
 これにより、センサ装置30は、第一開口部35bの大きさが変更されることにより、検知部31の検知範囲(検知感度)を変更することができる。 Thus, the sensor device 30 can change the detection range (detection sensitivity) of the detection unit 31 by changing the size of the first opening 35 b.
 なお、このような調整機構は、一例である。例えば、第一開口部35bには、カメラの絞りのような機構が調整機構として配置されていてもよい。 Such an adjustment mechanism is an example. For example, in the first opening 35b, a mechanism such as a diaphragm of a camera may be arranged as an adjustment mechanism.
 (実施の形態2)
 次に、実施の形態2に係るセンサ装置について説明する。図6は、実施の形態2に係るセンサ装置の内部構造を示す図である。
Second Embodiment
Next, a sensor device according to Embodiment 2 will be described. FIG. 6 is a view showing an internal structure of a sensor device according to a second embodiment.
 図6に示されるセンサ装置30aは、例えば、上述した照明システム100においてセンサ装置30の代わりに用いられる。以下、センサ装置30aについて、センサ装置30との相違点を中心に説明する。 The sensor device 30a shown in FIG. 6 is used, for example, in place of the sensor device 30 in the illumination system 100 described above. Hereinafter, the sensor device 30a will be described focusing on differences from the sensor device 30.
 センサ装置30aが備えるカバー部材35aには、貫通孔が設けられ、当該貫通孔は、透過率を調整可能な光学部材39で塞がれている。貫通孔は、具体的には、カバー部材35aのうち検知部31の受光面31cと対向する部分に設けられる。光学部材39は、調光フィルム、エレクトロクロミック素子、またはSPDなどである。光学部材39は、電圧の印加等の制御によって光の透過率が変化する部材であればよい。光学部材39への電圧の印加は、例えば、制御部32によって行われるが、他の制御部(制御回路)等によって行われてもよい。 A through hole is provided in the cover member 35a included in the sensor device 30a, and the through hole is closed by an optical member 39 whose transmittance can be adjusted. Specifically, the through hole is provided in a portion of the cover member 35 a facing the light receiving surface 31 c of the detection unit 31. The optical member 39 is a light control film, an electrochromic device, an SPD, or the like. The optical member 39 should just be a member from which the transmittance | permeability of light changes by control of application of a voltage etc. The application of the voltage to the optical member 39 is performed by, for example, the control unit 32, but may be performed by another control unit (control circuit) or the like.
 例えば、ユーザがリモートコントローラを通じて制御部32に電圧印加指示を行うような構成が考えられる。この場合、センサ装置30aは、リモートコントローラの赤外線信号を受信するための受光部(図示せず)を備える。 For example, a configuration is conceivable in which the user instructs the control unit 32 to apply a voltage through the remote controller. In this case, the sensor device 30a includes a light receiving unit (not shown) for receiving an infrared signal of the remote controller.
 このような構成により、センサ装置30aは、光学部材39の光の透過率が低いときには、天井40及び壁50の少なくとも一方の明るさを主な検知対象とすることができ、光学部材39の光の透過率が高いときには、床60(床面)または机上面などの明るさを検知部31の検知対象に含めることができる。 With such a configuration, when the light transmittance of the optical member 39 is low, the sensor device 30a can set the brightness of at least one of the ceiling 40 and the wall 50 as the main detection target, and the light of the optical member 39 When the transmissivity of is high, the brightness of the floor 60 (floor surface) or the desk surface can be included in the detection target of the detection unit 31.
 なお、光学部材39と同様の機能を得るために、カバー部材35aには、開口面積が調整可能な第二開口部が設けられてもよい。つまり、センサ装置30aは、さらに、カバー部材35aに設けられた第二開口部の開口面積を調整するための調整機構を備えてもよい。図7及び図8は、カバー部材35aに設けられた第二開口部の開口面積を調整するための調整機構を下方から見た斜視図である。 In order to obtain the same function as that of the optical member 39, the cover member 35a may be provided with a second opening whose opening area can be adjusted. That is, the sensor device 30a may further include an adjustment mechanism for adjusting the opening area of the second opening provided in the cover member 35a. FIGS. 7 and 8 are perspective views of the adjustment mechanism for adjusting the opening area of the second opening provided in the cover member 35a as viewed from below.
 図7及び図8に示される調整機構80は、上述した外郭筐体35の大径部に相当し、第一筐体81、及び、第一筐体81を外側から囲む第二筐体82の二重構造を有する。第一筐体81及び第二筐体82は、いずれも有底円筒状であり、筒軸が一致するように配置されている。第一筐体81及び第二筐体82は、いずれもカバー部材35aに相当する底面に略扇形の開口部が3つ設けられている。第一筐体81及び第二筐体82のそれぞれにおいて、3つの略扇形の開口部は、円周方向に並んで配置される。 The adjustment mechanism 80 shown in FIGS. 7 and 8 corresponds to the large-diameter portion of the outer casing 35 described above, and the first casing 81 and the second casing 82 surrounding the first casing 81 from the outside. It has a double structure. Each of the first housing 81 and the second housing 82 has a bottomed cylindrical shape, and is disposed such that the cylinder axes coincide with each other. In each of the first housing 81 and the second housing 82, three substantially fan-shaped openings are provided on the bottom surface corresponding to the cover member 35a. In each of the first housing 81 and the second housing 82, three substantially fan-shaped openings are arranged side by side in the circumferential direction.
 第一筐体81の底面に設けられた開口部と、第二筐体82の底面に設けられた開口部とは、下方から見て重なるように配置されている。第一筐体81の底面に設けられた開口部と、第二筐体82の底面に設けられた開口部との重なりによって形成される第二開口部83の開口面積は、第一筐体81に対して第二筐体82を筒軸回りに回動させることにより調整される。例えば、図7に示される状態で第二筐体82を第一筐体81に対して下方から見て時計回りに回動させると、図8に示されるように、第二開口部83の開口面積は小さくなる。図7及び図8の例では、第二開口部83は複数配置されているが、少なくとも1つ配置されればよい。 The opening provided on the bottom surface of the first housing 81 and the opening provided on the bottom surface of the second housing 82 are arranged so as to overlap from the bottom. The opening area of the second opening 83 formed by overlapping the opening provided on the bottom of the first housing 81 and the opening provided on the bottom of the second housing 82 is the same as that of the first housing 81. The adjustment is performed by rotating the second housing 82 about the cylinder axis. For example, when the second housing 82 is rotated clockwise as viewed from below with respect to the first housing 81 in the state shown in FIG. 7, the opening of the second opening 83 is formed as shown in FIG. 8. The area is smaller. Although the plurality of second openings 83 are arranged in the example of FIGS. 7 and 8, at least one second opening 83 may be arranged.
 なお、このような調整機構は、一例である。カバー部材35aには、カメラの絞りのような調整機構を有する第二開口部が設けられてもよい。 Such an adjustment mechanism is an example. The cover member 35a may be provided with a second opening having an adjustment mechanism such as a diaphragm of a camera.
 [実施の形態2の効果等]
 以上説明したように、カバー部材35aには、貫通孔が設けられ、当該貫通孔は、光の透過率を調整可能な光学部材39で塞がれていてもよい。
[Effects of Embodiment 2]
As described above, the cover member 35 a may be provided with a through hole, and the through hole may be closed by the optical member 39 whose light transmittance can be adjusted.
 これにより、センサ装置30aは、光学部材39の光の透過率が低いときには、天井40及び壁50の少なくとも一方の明るさを主な検知対象とすることができる。センサ装置30aは、光学部材39の光の透過率が高いときには、床60(床面)または机上面などの明るさを検知部31の検知対象に含めることができる。 Thus, when the light transmittance of the optical member 39 is low, the sensor device 30a can set the brightness of at least one of the ceiling 40 and the wall 50 as the main detection target. When the light transmittance of the optical member 39 is high, the sensor device 30a can include the brightness of the floor 60 (floor surface) or the desk surface as a detection target of the detection unit 31.
 また、カバー部材35aには、第二開口部が設けられ、センサ装置30aは、さらに、当該第二開口部の開口面積を調整するための調整機構(例えば、調整機構80)を備えてもよい。 In addition, the cover member 35a is provided with a second opening, and the sensor device 30a may further include an adjusting mechanism (for example, an adjusting mechanism 80) for adjusting the opening area of the second opening. .
 これにより、センサ装置30aは、第二開口部の開口面積が小さいときには、天井40及び壁50の少なくとも一方の明るさを主な検知対象とすることができる。センサ装置30aは、第二開口部の開口面積が大きいときには、床60(床面)または机上面などの明るさを検知部31の検知対象に含めることができる。 As a result, when the opening area of the second opening is small, the sensor device 30a can set the brightness of at least one of the ceiling 40 and the wall 50 as the main detection target. When the opening area of the second opening is large, the sensor device 30a can include the brightness of the floor 60 (floor surface) or the desk surface as the detection target of the detection unit 31.
 (実施の形態3)
 上記実施の形態1及び2では、検知部31(光電変換素子31a)とカバー部材35a(外郭筐体35)の組み合わせにより、検知部31が天井40及び壁50の少なくとも一方の明るさを検知した。しかしながら、検知部31が天井40及び壁50の少なくとも一方の明るさを検知する構成(センサ装置30またはセンサ装置30aの構成)は、上記実施の形態1及び2に限定されない。
Third Embodiment
In the first and second embodiments, the detection unit 31 detects the brightness of at least one of the ceiling 40 and the wall 50 by the combination of the detection unit 31 (photoelectric conversion element 31 a) and the cover member 35 a (outer casing 35). . However, the configuration in which the detection unit 31 detects the brightness of at least one of the ceiling 40 and the wall 50 (the configuration of the sensor device 30 or the sensor device 30a) is not limited to the first and second embodiments.
 例えば、検知部31及びカバー部材35aのそれぞれは、上記実施の形態1及び2と異なる形状であってもよい。また、検知部31及びカバー部材35aの配置は、実施の形態1及び2と異なってもよい。 For example, each of the detection unit 31 and the cover member 35a may have a shape different from those of the first and second embodiments. The arrangement of the detection unit 31 and the cover member 35a may be different from those in the first and second embodiments.
 以下、上記実施の形態1及び2とは異なる、検知部31が天井40及び壁50の少なくとも一方の明るさを検知する実施例について説明する。 Hereinafter, an embodiment in which the detection unit 31 detects the brightness of at least one of the ceiling 40 and the wall 50, which is different from the first and second embodiments, will be described.
 まず、第一実施例について説明する。図9は、実施の形態3の第一実施例を説明するための斜視図である。図10は、実施の形態3の第一実施例を説明するための断面図である。なお、以下の実施の形態3の図面においては、天井40に配置されるセンサ装置のうち、検知部及びカバー部材(外郭筐体)の配置のみが模式的に図示される。 First, the first embodiment will be described. FIG. 9 is a perspective view for explaining a first example of the third embodiment. FIG. 10 is a cross-sectional view for explaining a first example of the third embodiment. In the drawings of the third embodiment described below, only the arrangement of the detection unit and the cover member (outer casing) of the sensor device arranged on the ceiling 40 is schematically illustrated.
 図9及び図10に示されるように、第一実施例では、円板状の検知部90であって、受光面90aが上方(天井40側)を向いた状態の検知部90が、円錐状のカバー部材91内に配置される。カバー部材91(カバー部材91の縁部)は、検知部90(受光面90a)の検知範囲の一部を遮る。検知部90の受光面90aと反対側の面は、カバー部材91と対向する。 As shown in FIGS. 9 and 10, in the first embodiment, the detection unit 90 is a disc-shaped detection unit 90, and the detection unit 90 with the light receiving surface 90a facing upward (ceiling 40 side) has a conical shape. Is disposed in the cover member 91 of the second embodiment. The cover member 91 (edge of the cover member 91) blocks a part of the detection range of the detection unit 90 (light receiving surface 90a). The surface of the detection unit 90 opposite to the light receiving surface 90 a faces the cover member 91.
 図10に示されるように、天井40とカバー部材91との間には、第一開口部91aが形成される。第一実施例において、検知部90は、第一開口部91aを通って受光面90aに入る光の明るさを、天井40及び壁50(図9及び図10で図示せず)の少なくとも一方の明るさとして検知する。 As shown in FIG. 10, a first opening 91 a is formed between the ceiling 40 and the cover member 91. In the first embodiment, the detection unit 90 detects the brightness of light entering the light receiving surface 90a through the first opening 91a by at least one of the ceiling 40 and the wall 50 (not shown in FIGS. 9 and 10).

 次に、第二実施例について説明する。図11は、実施の形態3の第二実施例を説明するための分解斜視図である。図12は、実施の形態3の第二実施例を説明するための断面図である。 Next, a second embodiment will be described. FIG. 11 is an exploded perspective view for explaining a second example of the third embodiment. FIG. 12 is a cross-sectional view for explaining a second example of the third embodiment.
 図11及び図12に示されるように、第二実施例では、円板状の検知部90は、天井40に取り付けられた円錐台形状の台座92の下面に、受光面90aが下方(床60側)を向いた状態で配置される。つまり、検知部90の受光面90aは、天井40(検知対象の構造物)とは反対側を向いている。そして、受光面90aは、下方から円錐状のカバー部材91に覆われる。言い換えれば、カバー部材91は、受光面90aに対向配置され、検知部90(受光面90a)の検知範囲の一部を遮る。 As shown in FIGS. 11 and 12, in the second embodiment, the disk-shaped detection unit 90 has the light receiving surface 90 a located below the bottom surface of the truncated cone-shaped pedestal 92 attached to the ceiling 40 (floor 60 It is arranged with the side facing). That is, the light receiving surface 90 a of the detection unit 90 faces the opposite side to the ceiling 40 (the structure to be detected). The light receiving surface 90 a is covered by a conical cover member 91 from below. In other words, the cover member 91 is disposed to face the light receiving surface 90a, and blocks a part of the detection range of the detection unit 90 (the light receiving surface 90a).
 図12に示されるように、天井40とカバー部材91との間には、第一開口部91aが形成される。第二実施例において、検知部90は、第一開口部91aを通って受光面90aに入る光の明るさを、天井40及び壁50(図11及び図12で図示せず)の少なくとも一方の明るさとして検知する。 As shown in FIG. 12, a first opening 91 a is formed between the ceiling 40 and the cover member 91. In the second embodiment, the detection unit 90 detects the brightness of light entering the light receiving surface 90a through the first opening 91a by at least one of the ceiling 40 and the wall 50 (not shown in FIGS. 11 and 12). Detect as brightness.
 次に、第三実施例について説明する。図13は、実施の形態3の第三実施例を説明するための分解斜視図である。図14は、実施の形態3の第三実施例を説明するための断面図である。 Next, a third embodiment will be described. FIG. 13 is an exploded perspective view for explaining the third example of the third embodiment. FIG. 14 is a cross-sectional view for explaining a third example of the third embodiment.
 図13及び図14に示されるように、第三実施例では、天井40に取り付けられた四角錐台状の台座95が、四角錐状のカバー部材94によって下方から覆われる。台座95とカバー部材94との間には隙間が設けられ、隙間には、平面視形状が台形の検知部93がはめ込まれる。検知部93は、四角錐状のカバー部材94の各辺に対応して4つはめ込まれる。4つの検知部93は、受光面93aが外側を向くように、略四角錘台状に配置される。4つの検知部93の各受光面93aは、天井40側を向いている。カバー部材94は、4つの検知部93(4つの受光面93a)のそれぞれの検知範囲の一部を遮る。 As shown in FIGS. 13 and 14, in the third embodiment, a quadrangular pyramidal pedestal 95 attached to the ceiling 40 is covered from below by a quadrilateral pyramidal cover member 94. A gap is provided between the pedestal 95 and the cover member 94, and the detection portion 93 having a trapezoidal shape in plan view is fitted in the gap. The four detection portions 93 are fitted corresponding to each side of the quadrangular pyramidal cover member 94. The four detection units 93 are arranged in a substantially square pyramidal shape such that the light receiving surface 93 a faces outward. Each light receiving surface 93 a of the four detection units 93 faces the ceiling 40 side. The cover member 94 blocks part of the detection range of each of the four detection units 93 (four light receiving surfaces 93 a).
 また、天井40とカバー部材94との間には、第一開口部94aが形成される。 Further, a first opening 94 a is formed between the ceiling 40 and the cover member 94.
 第三実施例において、検知部93は、第一開口部94aを通って受光面93aに入る光の明るさを、天井40及び壁50(図13及び図14で図示せず)の少なくとも一方の明るさとして検知する。 In the third embodiment, the detection unit 93 detects the brightness of light entering the light receiving surface 93a through the first opening 94a by at least one of the ceiling 40 and the wall 50 (not shown in FIGS. 13 and 14). Detect as brightness.
 次に、第四実施例について説明する。図15は、実施の形態3の第四実施例を説明するための分解斜視図である。図16は、実施の形態3の第四実施例を説明するための断面図である。 Next, a fourth embodiment will be described. FIG. 15 is an exploded perspective view for explaining a fourth example of the third embodiment. FIG. 16 is a cross-sectional view for explaining a fourth example of the third embodiment.
 図15及び図16に示されるように、第四実施例では、天井40に取り付けられた四角錐台状の台座97が、四角錐状のカバー部材94によって下方から覆われる。台座97とカバー部材94との間には隙間が設けられ、隙間には、平面視形状が矩形の検知部96がはめ込まれる。検知部96は、四角錐状のカバー部材94の各辺に対応して4つはめ込まれる。4つの検知部96は、筒軸が上下方向(鉛直方向)に沿う角筒状に配置される。4つの検知部96のそれぞれは、受光面96aが外側(側方、壁50側)を向くように配置される。受光面96aは、カバー部材94と対向配置される。言い換えれば、カバー部材94は、4つの受光面96aのそれぞれと対向配置され、4つの検知部(4つの受光面96a)のそれぞれの検知範囲の一部を遮る。また、天井40とカバー部材94との間には、第一開口部94aが形成される。 As shown in FIGS. 15 and 16, in the fourth embodiment, a quadrangular pyramidal pedestal 97 attached to the ceiling 40 is covered from below by a quadrilateral pyramidal cover member 94. A gap is provided between the pedestal 97 and the cover member 94, and the detection portion 96 having a rectangular shape in plan view is fitted in the gap. Four detection portions 96 are fitted corresponding to each side of the quadrangular pyramidal cover member 94. The four detection units 96 are arranged in the shape of a rectangular cylinder whose cylinder axis extends in the vertical direction (vertical direction). Each of the four detection units 96 is arranged such that the light receiving surface 96 a faces the outer side (side, wall 50 side). The light receiving surface 96 a is disposed to face the cover member 94. In other words, the cover member 94 is disposed to face each of the four light receiving surfaces 96a, and blocks part of the detection range of each of the four detection units (four light receiving surfaces 96a). Further, a first opening 94 a is formed between the ceiling 40 and the cover member 94.
 第四実施例において、検知部96は、第一開口部94aを通って受光面96aに入る光の明るさを、天井40及び壁50(図15及び図16で図示せず)の少なくとも一方の明るさとして検知する。 In the fourth embodiment, the detection unit 96 detects the brightness of light entering the light receiving surface 96a through the first opening 94a by at least one of the ceiling 40 and the wall 50 (not shown in FIGS. 15 and 16). Detect as brightness.
 以上説明した第一実施例~第四実施例によっても、検知部は、床60(床面)の明るさを検知対象から除くことができる。つまり、検知部は、床60の明るさ、並びに、天井40及び壁50の少なくとも一方の明るさのうち、天井40及び壁50の少なくとも一方の明るさを選択的に検知することができる。 Also according to the first to fourth embodiments described above, the detection unit can exclude the brightness of the floor 60 (floor surface) from the detection targets. That is, the detection unit can selectively detect the brightness of at least one of the ceiling 40 and the wall 50 among the brightness of the floor 60 and the brightness of at least one of the ceiling 40 and the wall 50.
 なお、第一実施例~第四実施例は、上記実施の形態1または上記実施の形態2で説明された構成要素と組み合わされてもよい。例えば、第二実施例は、実施の形態1の調整機構70及び実施の形態2の調整機構80と組み合わされてもよい。図17は、第二実施例と調整機構70及び調整機構80との組み合わせを説明するための図である。 The first to fourth embodiments may be combined with the components described in the first embodiment or the second embodiment. For example, the second embodiment may be combined with the adjusting mechanism 70 of the first embodiment and the adjusting mechanism 80 of the second embodiment. FIG. 17 is a view for explaining a combination of the second embodiment and the adjusting mechanism 70 and the adjusting mechanism 80. In FIG.
 図17に示される構成の、第二実施例との違いは、カバー部材91の頂部に第二開口部91bが設けられていることである。ここで、頂部に設けられた第二開口部91bには、調整機構80のように、開口面積を調整できる機構が適用可能である。一方、台座95とカバー部材94との間の第一開口部91aには、調整機構70のように、開口面積を調整できる機構が適用可能である。 The difference of the configuration shown in FIG. 17 from the second embodiment is that a second opening 91 b is provided at the top of the cover member 91. Here, a mechanism capable of adjusting the opening area like the adjusting mechanism 80 is applicable to the second opening 91 b provided at the top. On the other hand, a mechanism capable of adjusting the opening area like the adjustment mechanism 70 is applicable to the first opening 91 a between the pedestal 95 and the cover member 94.
