[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and repeated description thereof will be omitted.

[0018] A detection unit 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a diagram showing the detection unit 1 according to an embodiment of the present invention. FIG. 2 is a diagram showing an arrangement surface of detection elements 11 in the detection unit 1 according to an embodiment of the present invention. FIG. 3 is a diagram showing an arrangement surface of a mounting portion 13 in the detection unit 1 according to an embodiment of the present invention. FIG. 4 is a diagram showing a surface intersecting both the arrangement surface of the detection elements 11 and the arrangement surface of the mounting portion 13 in the detection unit 1 according to an embodiment of the present invention.

[0019] The detection unit 1 detects the surrounding condition of the detection unit 1. For example, the detection unit 1 is equipped with a human motion sensor that detects "persons" around the detection unit 1. For example, the detection unit 1 is used together with a lighting device. The detection unit 1 and the lighting device are connected to each other by wire or wirelessly. The detection unit 1 transmits a signal indicating a detection result to the lighting device. The lighting device controls turning on or off of a light source of the lighting device based on the signal indicating the detection result transmitted from the detection unit 1.

[0020] As shown in FIGS. 1 and 2, the detection unit 1 includes a detection element 11, a housing 12, and a mounting portion 13. The detection element 11 is, for example, an infrared sensor that detects infrared rays, which is an example of electromagnetic waves. The detection element 11 is driven by power supplied from, for example, a battery (not shown) housed in the housing 12. The detection element 11 has a hemispherical optical element 11A and a light-receiving arithmetic element (not shown). The optical element 11A guides infrared rays emitted from a detection region to the light-receiving arithmetic element. The optical element 11A is a condenser lens or a Fresnel lens. The optical element 11A is formed using, for example, a resin material such as acrylic (PMMA) or polycarbonate (PC).

[0021] The light-receiving processing element receives infrared light that has passed through the optical element 11A and measures the amount of infrared light. The amount of infrared light measured by the light-receiving processing element is transmitted to the lighting device, etc., by the communication unit 14 described later.

[0022] The housing 12 houses a battery and a circuit board, etc. (not shown). A detection element 11 is mounted on the circuit board. The detection element 11 is electrically connected to the battery via the circuit board. The housing 12 has, for example, a hexahedral shape. In Figures 1 and 2, the housing 12 is a roughly rectangular parallelepiped. The housing 12 includes a first surface 12A on which the detection element 11 is arranged, a second surface 12B on which the mounting portion 13 is arranged, and four connecting surfaces 12C, 12D, 12E, and 12F that connect the first surface 12A and the second surface 12B. The housing 12 is made of an insulating resin material such as PBT (polybutylene terephthalate).

[0023] The hemispherical surface of the optical element 11A in the detection element 11 protrudes outward from the first surface 12A. The second surface 12B is a surface in the housing 12 that faces in the opposite direction DR to the direction in which the hemisphere faces along the axis P1 passing through the zenith of the hemisphere. The connecting surfaces 12C and 12E are located on opposite sides of each other with respect to the first direction D1 perpendicular to direction DR, with the first surface 12A or the second surface 12B in between. The connecting surfaces 12D and 12F are located on opposite sides of each other with respect to direction DR and the second direction D2 perpendicular to the first direction D1, with respect to the first surface 12A or the second surface 12B in between. The connecting surface 12C connects the edge of one side D1a of the first surface 12A in the first direction D1 to the edge of one side D1a of the second surface 12B in the first direction D1. The connecting surface 12D connects the edge D2a on one side of the second direction D2 of the first surface 12A to the edge D2a on one side of the second direction D2 of the second surface 12B. The connecting surface 12E connects the edge D1b on the other side of the first direction D1 of the first surface 12A to the edge D1b on the other side of the first direction D1 of the second surface 12B. The connecting surface 12F connects the edge D2b on the other side of the second direction D2 of the first surface 12A to the edge D2b on the other side of the second direction D2 of the second surface 12B.

[0024] In the housing 12, the first surface 12A and the four connecting surfaces 12C, 12D, 12E, and 12F are connected in a curved manner, but the first surface 12A and the four connecting surfaces 12C, 12D, 12E, and 12F may be connected without curving. Similarly, the second surface 12B and the four connecting surfaces 12C, 12D, 12E, and 12F are connected in a curved manner, but the second surface 12B and the four connecting surfaces 12C, 12D, 12E, and 12F may be connected without curving. Furthermore, although the four connecting surfaces 12C, 12D, 12E, and 12F are each connected in a curved manner, the four connecting surfaces 12C, 12D, 12E, and 12F may be connected without curving.

[0025] In this embodiment, the first surface 12A is planar. For example, the first surface 12A has a longitudinal shape along the first direction D1 of the two mutually orthogonal first and second directions D2. Specifically, the width W1 of the first surface 12A along the first direction D1 is longer than the width W2 of the first surface 12A along the second direction D2. This makes it easy to determine the mounting direction of the detection unit 1 based on the shape of the housing 12 and the position of the detection element 11. Furthermore, by making the distance between the first surface 12A and the second surface 12B, that is, the width of the four connection surfaces 12C, 12D, 12E, and 12F smaller than the width W2, the shape of the housing 12 can be made thin, allowing various components to be arranged planarly along the longitudinal direction, thus reducing the thickness of the detection unit 1. In addition, because the housing 12 is thin, the amount of protrusion from the mounting body is reduced, which helps to prevent contact with the detection unit 1 when a user passes near it.

[0026] As shown in Figures 1 and 3, the second surface 12B has the same shape as the first surface 12A. The four connecting surfaces 12C, 12D, 12E, and 12F are planar in shape.

[0027] Furthermore, the first surface 12A, the second surface 12B, and the four connecting surfaces 12C, 12D, 12E, and 12F may have a curved shape.

[0028] As shown in Figure 2, the detection element 11 is located on one side D1a of the first direction D1 from the center C1 of the first surface 12A. In Figure 2, the detection element 11 is located at the same position as the center C1 of the first surface 12A in the second direction D2, but the detection element 11 may also be located on one side D2a of the second direction D2 from the center C1 of the first surface 12A, or on one side D2a of the second direction D2 from the center C1 of the first surface 12A. In other words, the detection element 11 is located on the edge side of the first surface 12A from the center C1 of the first surface 12A.

[0029] Next, the mounting portion 13 will be described. As shown in Figures 1 and 3, the mounting portion 13 is located on the second surface 12B of the housing 12. The mounting portion 13 is located on one side D1a of the first direction D1 from the center C1 of the second surface 12B.

[0030] As shown in Figures 3 and 4, the mounting portion 13 includes a column portion 131. The column portion 131 extends from the second surface 12B of the housing 12 toward the opposite side of the first surface 12A. In other words, the column portion 131 is a columnar member that extends from the second surface 12B toward the outside of the housing 12. The column portion 131 is made of an insulating resin material such as PBT (polybutylene terephthalate), the same material as the housing 12.

[0031] The column portion 131 includes a recess 132. The recess 132 is recessed in a hemispherical shape toward the second surface 12B at the end 131A of the column portion 131 opposite to the second surface 12B. The recess 132 is made of, for example, a magnet. In other words, the mounting portion 13 includes a magnet. For example, in the mounting portion 13, the column portion 131 may be made of a magnet in addition to the recess 132. In this case, the surface of the recess 132 facing away from the second surface 12B may have the magnet exposed, or it may be covered by the insulating resin material of the column portion 131. Therefore, the detection unit 1 can be easily attached to and detached from metal.

[0032] Next, the mounting of the detection unit 1 to the mounting body will be explained with reference to Figures 4 and 5. Figure 5 shows the mounting of the detection unit 1 to the mounting body. In Figure 5, a part of the mounting portion 13 is made transparent for easier understanding.

[0033] As shown in Figure 5, the detection unit 1 is attached to a wall H, for example. The wall H is just one example of a mounting surface. The mounting surface is not limited to a wall H; it may also be a ceiling or floor. Furthermore, the mounting surface is not limited to a fixed surface such as a wall H, ceiling, or floor; it may also be a portable object such as a desk, chair, or shelf.

[0034] For example, a mounting base 133 is provided on the wall H. The detection unit 1 is attached to the mounting base 133. In other words, the detection unit 1 is supported by the mounting base 133. In this embodiment, the mounting base 133 is an example of a support part. The mounting base 133 has a hemispherical shape corresponding to the recess 132 of the mounting part 13. The mounting base 133 is fixed to the wall H by screws, for example. Note that the mounting base 133 may also be fixed to the wall H by methods other than screwing, such as adhesive.

[0035] In this embodiment, the shape of the recess 132 is the same as the zenith portion 134 of the mounting base 133. The zenith portion 134 is the region from the zenith of the mounting base 133 to a predetermined distance around the zenith. In other words, the distance R3 from the end portion 131A of the column portion 131 in the recess 132 to the zenith of the recess 132 is shorter than the distance R4 from the surface of the wall H of the mounting base 133 to the zenith of the mounting base 133. Also, the diameter R2 of the recess 132 at the end portion 131A is shorter than the diameter R1 of the mounting base 133 on the surface of the wall H. Therefore, the recess 132 fits into a part of the mounting base 133.

[0036] The mounting base 133 is made of metal and is attracted to magnets. In other words, the mounting base 133 and the recess 132 are attracted to each other. When the mounting base 133 and the recess 132 are attracted to each other, the recess 132 is movable relative to the mounting base 133. In other words, the mounting base 133 and the recess 132 constitute a flexible joint. Therefore, the mounting portion 13 can freely adjust the angle of the housing 12 with respect to the surface of the wall H.

[0037] Next, the mounting angle of the detection unit 1 will be explained with reference to Figures 5 to 7. Figure 6 shows an example of the detection unit 1 mounted on a wall H via a mounting base 133. Figure 7 shows another example of the detection unit 1 mounted on a wall H via a mounting base 133. Figures 5, 6, and 7 show that the mounting angles of the detection unit 1 relative to the wall H are different from each other.

[0038] Figure 5 shows the detection unit 1 mounted on the mounting base 133 such that the first surface 12A of the detection unit 1 is parallel to the surface of the wall H. In this state, the direction DR in which the hemisphere faces along the axis P1 passing through the zenith of the hemisphere is perpendicular to the surface of the wall H. The detection element 11 detects infrared radiation incident on the detection element 11 from the detection region E1. The detection region E1 is a roughly conical shape that extends at an angle α1 around the axis P1 passing through the zenith of the optical element 11A.

[0039] Figure 6 shows the state in which the detection unit 1 is mounted on the mounting base 133 such that, compared to the state in Figure 5, one side D1a of the first surface 12A of the detection unit 1 is closer to the wall H. In this state, direction DR is inclined at an angle β1 from the direction perpendicular to the surface of the wall H. In other words, the detection region E1 in Figure 6 is inclined at an angle β1 compared to the detection region E1 in Figure 5.

[0040] Figure 7 shows the state in which the detection unit 1 is mounted on the mounting base 133 such that the other side D1b of the first surface 12A of the detection unit 1 is closer to the wall H, compared to the state in Figure 5. In this state, the direction DR is tilted by an angle β2 from the direction perpendicular to the surface of the wall H to the opposite side of the tilt in the state in Figure 6. In other words, the detection region E1 in Figure 6 is tilted by an angle β2 relative to the detection region E1 in Figure 5. As shown in Figures 6 and 7, since the mounting portion 13 is located on one side D1a of the first direction D1 from the center C2 of the second surface 12B, the movable range of the mounting angle of one side D1a of the housing 12 in the first direction D1 is larger than the movable range of the mounting angle of the other side D1b of the housing 12 in the first direction D1. Also, the shorter the distance from the detection element 11 to the edge of the first surface 12A, the greater the tilt of the detection region E1 (angle β1 > angle β2). In other words, in this embodiment, the detection region E1 can be directed more towards one side D1a of the first direction D1. Thus, because the range of motion for the mounting angle differs between one side D1a and the other side D1b of the first direction D1, the tilt of the detection region E1 can be easily adjusted to any desired angle. For example, the tilt of the detection region E1 can be adjusted simply by reversing the mounting direction of the detection unit 1 relative to the first direction D1.

[0041] Furthermore, since the width W2 in the second direction D2 is narrower than the width W1 in the first direction D1 on the first surface 12A of the detection unit 1, the range of motion of the mounting angle of the housing 12 with respect to the second direction D2 is greater than the range of motion of the mounting angle of the housing 12 with respect to the first direction D1.

[0042] Next, with reference to Figure 3, the communication unit 14 of the detection unit 1 according to an embodiment of the present invention will be described.

[0043] The detection unit 1 includes a communication unit 14. The communication unit 14 transmits the detection result of the detection element 11 to an external device of the detection unit 1, such as a lighting device, via a network. For example, the communication unit 14 is a wireless communication module that performs wireless communication. The communication unit 14 is composed of circuit elements such as an IC (Integrated Circuit) or FPGA (Field Programmable Gate Array) and is mounted on a circuit board. The communication unit 14 is electrically connected to the detection element 11 and the battery via the circuit board. The network includes, for example, the Internet, LAN (Local Area Network), and public telephone networks. Specifically, the communication unit 14 includes, for example, a network interface controller (NIC) that communicates according to a predetermined communication protocol, or a communication device conforming to communication standards such as Bluetooth® or WiFi. The predetermined communication protocol is, for example, the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol suite (i.e., the Internet Protocol Suite).

[0044] Specifically, the light receiving processing element of the detection element 11 outputs an electrical signal containing information indicating the amount of infrared radiation, which is the measurement result, to the communication unit 14. When the communication unit 14 receives the electrical signal output from the detection element 11, it acquires the measurement result contained in the electrical signal and transmits the acquired measurement result to an external device via the network according to a predetermined communication protocol. Therefore, the detection result of the detection unit 1 becomes easily available to the external device.

[0045] Next, with reference to Figure 3, the operation unit 15, notification unit 17, and control unit 18 of the detection unit 1 according to an embodiment of the present invention will be described.

[0046] The operation unit 15 receives user input to the detection unit 1. The operation unit 15 is, for example, a push-button switch mounted on a circuit board. The operation unit 15 is electrically connected to the control unit 18, which will be described later, via the circuit board. On the second surface 12B of the detection unit 1, a circular through-hole 16 is positioned at the location corresponding to the operation unit 15. The through-hole 16 penetrates the second surface 12B in the direction DR towards the detection element 11. For example, the switch can be pressed by inserting a pin or the like into the through-hole 16 from outside the detection unit 1. Note that the shape of the through-hole 16 is not limited to a circle.

[0047] The notification unit 17 is, for example, a light-emitting element such as an LED (Light Emitting Diode) mounted on a circuit board. The notification unit 17 is electrically connected to the control unit 18, which will be described later, via the circuit board. On the second surface 12B of the detection unit 1, a circular hole 19 is positioned at the location corresponding to the notification unit 17. The hole 19 extends, for example, along the direction DR in which the detection element 11 faces, and penetrates the second surface 12B. Light emitted from the notification unit 17 passes through the hole 19 and reaches the outside of the detection unit 1. Note that the shape of the hole 19 is not limited to a circle.

[0048] For example, by making the size of hole 19 smaller than the size of through hole 16, the possibility of a pin being mistakenly inserted into hole 19 can be reduced.

[0049] The control unit 18 is composed of circuit elements such as ICs or FPGAs mounted on a circuit board and controls the communication unit 14 and the notification unit 17. The control unit 18 is electrically connected to the detection element 11, the communication unit 14, the operation unit 15, the notification unit 17, and a battery (not shown) via the circuit board. Specifically, the control unit 18 executes predetermined functions of the communication unit 14 or controls the lighting or extinguishing of the light-emitting element according to the state of the switch. In this embodiment, the control unit 18 and the communication unit 14 are different circuit elements, but the control unit 18 and the communication unit 14 may be composed of a single circuit element.

[0050] Specifically, if the communication unit 14 is a wireless communication module that communicates according to Bluetooth, when the switch is pressed for a predetermined period (for example, 5 seconds), the control unit 18 controls the communication unit 14 so that it transitions to pairing mode, and also controls the notification unit 17 so that the light-emitting element blinks at predetermined intervals.

[0051] Furthermore, if the switch is pressed for a predetermined period of time (for example, 20 seconds), the control unit 18 controls the communication unit 14 to reset its settings.

[0052] By providing the operation unit 15 and notification unit 17 on the second surface 12B of the detection unit 1, the user can operate the operation unit 15 while checking the status of the notification unit 17. Therefore, the user can easily check whether the communication unit 14 is in pairing mode, making it easier to prevent erroneous operations such as pressing a switch too many times.

[0053] Next, an example of the hole 19 will be described with reference to Figure 8. Figure 8 is a cross-sectional view of the hole 19 of the detection unit 1 according to an embodiment of the present invention. Figure 8 is an enlarged view of a part of the cross section that passes through the central axis P3 of the hole 19 shown in Figure 3 and the central axis P2 of the notification unit 17, and is perpendicular to the second surface 12B of the detection unit 1.

[0054] The hole 19 has a tapered portion 19A and a connecting portion 19B. The tapered portion 19A is located on the notification portion 17 side of the hole 19, and its diameter decreases towards the second surface 12B side. The connecting portion 19B is located on the second surface 12B side of the hole 19 and connects to the tapered portion 19A. The connecting portion 19B connects the second surface 12B side of the tapered portion 19A and the surface of the second surface 12B in a straight line along the direction DR in which the detection element 11 faces.

[0055] As shown in Figure 8, the tapered section 19A's wall tapers along the direction of light L emission, causing the light L emitted from the notification section 17 to reflect and scatter off the wall of the tapered section 19A, making the light L easier to see from outside the housing 12. Therefore, even if, for example, the central axis P3 of the hole 19 and the central axis P2 of the notification section 17 are misaligned due to manufacturing tolerances, unlike when the diameter of the hole 19 is constant, the light L is less likely to be obstructed by the housing 12. As a result, the light L emitted from the notification section 17 can more easily reach outside the housing 12, making it easier for the user to see the light L. Although the tapered section 19A's wall is curved in Figure 8, the tapered section 19A's wall does not have to be curved.

[0056] In this embodiment, the detection element 11 is configured to output information indicating the amount of infrared radiation, which is the measurement result from the light-receiving processing element, as a detection result. However, for example, the detection element 11 may also output as a detection result the determination result of whether or not a detection target such as a "person" exists in the detection area E1 based on the change in the amount of infrared radiation, as determined by the light-receiving processing element. Specifically, the light-receiving processing element performs calculation processing on the measured amount of infrared radiation to calculate the change in the amount of received infrared radiation. For example, if the amount of infrared radiation in the detection area E1 increases or decreases by more than a threshold, the light-receiving processing element determines that a detection target exists in the detection area E1 and outputs an electrical signal indicating the presence of the detection target to the communication unit 14.

[0057] In this embodiment, the detection element 11, communication unit 14, notification unit 17, and control unit 18 are configured to be driven by power supplied from a battery. However, the detection element 11, communication unit 14, notification unit 17, and control unit 18 may also be driven by power supplied from an external source other than a battery.

[0058] In this embodiment, the shape of the mounting base 133 and the shape of the mounting portion 13 may be reversed. In this case, the mounting portion 13 includes a magnet.

[0059] Furthermore, the mounting base 133 and the mounting part 13 may be attached to each other not only by magnetic attraction, but also by fitting claws and slits together.

[0060] Furthermore, the shape of the mounting portion 13 is not limited to the shapes shown in Figures 4 to 7. For example, the mounting portion 13 does not need to have a recess 132. Even in this case, for example, if the housing 12 is supported by the mounting portion 13 and one side D2a of the second direction D2 of the second surface 12B, the mounting angle of the housing 12 will be larger than when the housing 12 is supported by the mounting portion 13 and the other side D1b of the first direction D1 of the second surface 12B. Therefore, the angle of the housing 12 relative to the mounting body can be easily adjusted by changing the orientation of the housing 12.

[0061] In this embodiment, the shape of the housing 12 is not limited to a rectangular parallelepiped. For example, the shape of the first surface 12A may be an ellipse, an oval, or a triangle. In other words, the first surface 12A only needs to have a shape in which the width W1 in the first direction D1 is longer than the width W2 in the second direction D2.

[0062] In this embodiment, the hole 19 does not have to be a through hole. Specifically, the inside side of the housing 12 of the hole 19 may be sealed with a light-transmitting resin or the like. This prevents the notification unit 17 from coming into contact with the pin even if it is mistakenly inserted into the hole 19.

[0063] In this embodiment, the detection element 11 is a human presence sensor, but for example, the detection element 11 may be an illuminance sensor that detects visible light, which is an example of electromagnetic waves, to measure illuminance. Since the mounting angle of the housing 12 of the detection unit 1 according to this embodiment is adjustable, the detection unit 1 can be mounted at an angle that detects illuminance only in an arbitrary direction, or at an angle that does not detect illuminance in another arbitrary direction. The detection element 11 may also be a sensor that detects electromagnetic waves having wavelengths other than infrared and visible light.

[0064] In this embodiment, the detection element 11 may include a cover member that covers a part of the optical element 11A and limits the detection area E1. For example, if the mounting direction of the cover member is fixed to the housing 12, the user can easily determine which direction of the detection area E1 is limited, based on the shape of the housing 12, using the first direction D1 or the second direction D2 as a reference.

[0065] In this embodiment, when the communication unit 14 communicates according to Bluetooth, the communication unit 14 communicates with a paired device, for example, and transmits and receives signals with the paired device. The communication unit 14 may also communicate according to a communication standard other than Bluetooth. In this case, the communication unit 14 may only have a signal transmission function.
