The opposing U-shaped piece is provided with a hole 2a through which the rotating shaft 1x of the cylindrical main body 1 is inserted to support and rotate the cylindrical main body 1.

The printed circuit board 4 has a substantially square shape, and the sensor element 3 is mounted at the center thereof. Here, when the surface on which the sensor element 3 of the printed circuit board 4 is mounted is the sensor element mounting surface 4a and the surface opposite to the sensor element mounting surface 4a is the non-sensor element mounting surface 4b, the printed circuit board 4 is The sensor body mounting surface 4a is accommodated in the cylindrical main body 1 so as to face the inner surface of the light receiving surface 1a. Thereby, the light receiving part 3a of the sensor element 3 is mounted toward the inner surface of the light receiving surface 1a.
Here, the relationship between the light receiving portion 3a of the sensor element 3 and the light receiving surface 1a is that light introduced from the light receiving surface 1a provided at a predetermined angle on the side peripheral surface of the cylindrical main body 1 is received by the sensor element 3. The light can be condensed and received by the portion 3a. In the case shown in FIG. 1, light introduced from an angle of about 120 ° can be condensed on the light receiving portion 3a.
The electric wire 5 is connected to the printed circuit board 4 from the surface opposite to the surface on which the sensor element 3 of the printed circuit board 4 is mounted, that is, from the non-sensor element mounting surface 4 b to the printed circuit board 4.

  What is important here is that a space X2 communicating with the internal space X1 of the cylindrical main body 1 is formed on the wall portion of the cylindrical main body 1 facing the surface to which the electric wires 5 of the printed circuit board 4 are connected, that is, the non-sensor element mounting surface 4b. The extending piece 1c is provided so as to protrude from the cylindrical main body 1, the electric wire 5 is pulled out from the extending piece 1c, and the display unit can recognize that the light receiving surface is at a predetermined angle in the vicinity of the extending piece 1c. 2b is provided.

More specifically, the extending piece 1c is in the form of a hollow plate, and its base end is formed integrally with the cylindrical main body 1. The extending piece 1c is away from the light receiving surface 1a from the position rotated about 180 ° around the circumference of the cylindrical main body 1 with respect to the approximate center 1ax of the light receiving surface 1a provided on the cylindrical main body 1, that is, the diameter. It has been extended outward in the direction. Moreover, the electric wire 5 is wired in the space X2 of the extended piece 1c, and this electric wire 5 is pulled out from the front-end | tip of the extended piece 1c.
Further, near the tip of the extended piece 1c, convex engagement portions 1cd projecting in the same direction as the rotation shaft 1x of the cylindrical main body 1 are provided on both sides thereof. A plurality of concave locking portions 2d that lock the engaging portions 1cd are provided on the opposing pieces. The light receiving surface 1a can be positioned at a predetermined angle by locking the engaging portion 1cd with the locking portion 2d.
The display portion 2d is provided in a one-to-one correspondence with the locking portion 2d in the vicinity of the concave locking portion 2d that locks the engaging portion 1cd provided near the tip of the extended piece 1c.

Next, assembly of the human sensor unit will be described. Here, the cylindrical main body 1 and the extending piece 1c integrated therewith are one cylindrical main body 1 side part and the other cylindrical main body 1 side on a plane perpendicular to the rotation axis 1x of the cylindrical main body 1. It can be divided into parts. The cylindrical main body 1 is provided with a light receiving surface slit capable of positioning the light receiving surface 1a at a predetermined position and a printed circuit board slit capable of positioning the printed circuit board 4 at a predetermined position. Further, it is assumed that the mounting of the sensor element 3 and the connection of the electric wire 5 are completed on the printed circuit board 4.
The human sensor unit is assembled by inserting the light receiving surface 1a into the light receiving surface slit of one of the cylindrical body 1 side components, and further inserting the printed circuit board 4 into the printed circuit board slit. Thereby, the printed circuit board 4 is set to the cylindrical main body 1 so that the sensor element mounting surface 4a faces the inner surface of the light receiving surface 1a. Furthermore, the electric wire 5 in the internal space X1 of the cylindrical main body 1 is pulled out from the tip of the extended piece 1c through the space X2 of the extended piece 1c communicating with this space. In this state, the other cylindrical body 1 side part is fixed to the one cylindrical body 1 side part by bonding, fitting, or the like. Further, the rotating shaft 1x of the cylindrical main body 1 is inserted into the hole 2a of the support 2 and the engaging portion 1cd at the tip of the extending piece 1c is inserted into the locking portion 2d of the support 2. Thereby, the assembly of the human sensor unit is completed.

In this human sensor unit, the electric wire 5 can be connected to the printed circuit board 4 by using the space X2 inside the extending piece 1c, so the connection space of the electric wire 5 in the human sensor unit (the electric wire 5 is printed). The connection space when connecting to the substrate 4 can be expanded. Furthermore, the space X2 inside the extended piece 1c at a position where the distance between the inner surface of the cylindrical main body 1 and the printed circuit board 4 is farthest, that is, a position where the inner surface of the cylindrical main body 1 is most bulged when viewed from the printed circuit board 4. Therefore, the connection space for connecting the electric wire 5 to the printed circuit board 4 can be further expanded.
In addition, this human sensor unit is configured such that the engaging portion 1cd at the tip of the extending piece 1c is engaged with the engaging portion 2d of the support 2 so as to be freely disengaged. The angle of the light receiving surface 1a can be maintained at a desired angle. In particular, since the display unit 2b is provided near the tip of the extended piece 1c further away from the cylindrical body 1, the display unit 2b is not as small as the human sensor unit described with reference to FIG. Therefore, since individual numbers can be made large and easy to read, the adjustment work when adjusting the mounting angle of the cylindrical main body 1 can be easily performed.

Next, an example in which this human sensor unit is used in the lighting fixture described in FIG. 11 will be described. In this, 100a is a human sensor unit attached to each of both ends of the luminaire 100. This luminaire 100 is a luminaire that is installed at the landing of a staircase, and by adjusting the light receiving surface 1a of each sensation sensor unit up and down appropriately, the one sensation sensor unit Detects the presence or absence of the detection target of the stairs above the landing, and the other human sensor unit detects the presence or absence of the detection target of the stairs below the landing . FIG. 4 is a diagram for explaining this situation, and FIG. 4 (a) is set so that one human sensor unit can detect the presence or absence of a detection target of a staircase located above the landing. FIG. 4B is a set in which the other human sensor unit can detect the presence / absence of the detection target of the stairs below the landing. In the figure, 100k is a front panel of the lighting fixture 100, and 100ka is a window provided on the front panel 100k. The human sensor unit is attached to the luminaire 100 so that approximately half of the cylindrical main body 1 of the human sensor unit protrudes from a window 100ka provided on the front panel 100.
Here, the lighting fixtures installed at the landing stage of the stairs often adjust the detection range in the dark. Therefore, by using the human sensor unit with the enlarged display unit 2b as described above, the adjustment can be further improved. It will be easy to do.

  According to this embodiment, the extending piece 1c having the space X2 communicating with the internal space X1 of the cylindrical main body 1 on the wall portion of the cylindrical main body 1 facing the surface to which the electric wire 5 of the printed circuit board 4 is connected. By providing the cylindrical body 1 so as to protrude from the extended piece 1c, and by providing a display 2b that can recognize that the light receiving surface 1a is at a predetermined angle in the vicinity of the extended piece 1c. Since the electric wire provided for transmitting the signal from the inside of the human sensor unit to the outside can be connected to the printed circuit board 4 using the space X2 communicated with the internal space X1 of the cylindrical main body 1, The connection space of the electric wire 5 in the human sensor unit can be expanded. Furthermore, since the display part 2b to be confirmed when adjusting the angle of the light receiving part 1a of the human sensor unit is provided in the vicinity of the extended piece 1c provided so as to protrude from the cylindrical main body 1, the display is enlarged. The visibility can be improved.

  The surface on which the sensor element 3 of the printed circuit board 4 is mounted is defined as a sensor element mounting surface 4a. The printed circuit board 4 is accommodated in the cylindrical main body 1 so that the sensor element mounting surface 4a faces the inner surface of the light receiving surface 1a. The electric wire 5 is connected to the printed circuit board 4 at the non-sensor element mounting surface 4b opposite to the sensor element mounting surface 4a, and the wall portion of the cylindrical main body 1 facing the non-sensor element mounting surface 4b of the printed circuit board 4 Since the extending piece 1c is formed on the wire 5, the wire 5 can be processed only by the non-sensor element mounting surface 4b. As a result, when the electric wire 5 is pulled out of the cylindrical main body 1, the electric wire 5 floats in the direction of the light receiving surface 1 a, and the electric wire 5 blocks light that should enter the light receiving portion 3 a of the sensor element 3. Disappears. This will be described in detail. FIG. 5 is a cross-sectional view of the human sensor unit in which an extending piece 1c is formed on the wall portion of the cylindrical main body 1 facing the sensor element mounting surface 4a of the printed board 4 for explaining this. In this case, when a sensor element 3 having a low height of about several millimeters is used, when the electric wire 5 connected to the printed circuit board 4 is pulled out of the cylindrical body 1, the electric wire 5 is a light receiving surface. May float in the direction of 1a, and the electric wire 5 may block light that should enter the light receiving portion 3a of the sensor element 3. In particular, when the electric wire 5 is connected to the printed circuit board 4 via a connection connector or the like, the mounting height of the connection connector may be close to 1 cm. Therefore, the electric wire 5 is sufficiently larger than the height of the sensor element 3. It will be led to the drawer opening of the cylindrical main body 1 from a high position, and the electric wire 5 will often affect the light receiving performance of the sensor element 3. In order to prevent this, the human sensor unit described with reference to FIG. 1 connects the electric wire 5 to the printed circuit board 4 on the surface opposite to the surface on which the sensor element 3 of the printed circuit board 4 is mounted. The electric wire 5 is drawn out from the wall portion of the cylindrical main body 1 facing the surface opposite to the surface on which the element 3 is mounted.

The extending piece 1c is extended in a direction away from the light receiving surface 1a from a position rotated about 180 ° on the circumference of the cylindrical main body 1 with respect to the approximate center of the light receiving surface 1a provided on the cylindrical main body 1. As a result, when the human sensor unit is mounted so that approximately half of the cylindrical main body 1 of the human sensor unit protrudes from the window 100ka provided on the front panel 100K of the lighting device 100, the cylinder The main body 1 can be rotated in substantially the same range in either direction on the circumference, and the light receiving surface 1a does not enter the back side of the front panel 100k, and the rotation range can be widened.
Further, the extended piece 1c for expanding the connection space of the electric wire 5 is located at a position where the distance between the inner surface of the cylindrical main body 1 and the printed circuit board 4 is farthest, that is, the inner surface of the cylindrical main body 1 when viewed from the printed circuit board 4. Since the space X2 in the extension piece 1c is communicated at the most swelled portion, the connection space for connecting the electric wire 5 to the printed circuit board 4 can be further expanded.
Further, since the extending piece 1c is extended in the radial direction of the cylindrical main body 1, it can be seen that the extending direction of the extending piece 1c is the direction of the light receiving surface 1a. It is easy to adjust the angle.
Further, the light receiving surface 1a can be positioned at a predetermined position by locking a part of the extended piece 1c. In particular, an engaging portion 1cd is provided near the tip of the extended piece 1c, and the support 2 is provided. Is provided with a locking portion 2b for locking the engaging portion 1cd. By locking the engaging portion 1cd with the locking portion 2b, the light receiving surface 1a can be positioned at a predetermined angle, and the display portion 2b is locked with the locking portion 2d. By providing it in the vicinity, the display can be further enlarged.

Next, an application example of this embodiment will be described. FIG. 6 shows an extension piece 1c that is longer than that described with reference to FIG. This has a smaller rotation angle than the one described with reference to FIG. The same components as those described in the other embodiments are denoted by the same reference numerals, and description thereof is omitted. In this structure, since the shape of the concave locking portion 2d for locking the engaging portion 1cd can be increased even if the rotation angle is small, the click feeling when the cylindrical main body 1 is rotated is likely to occur and the size is reduced. Even a human sensor unit that has been made can be easily operated.
FIG. 7 shows another application example, and FIG. 7 is a perspective view of the human sensor unit. In this case, a position for drawing out the electric wire 5 from the extended piece 1c is defined as an electric wire drawn position 1ca, and the electric wire drawn position 1ca is provided in front of the tip of the extended piece 1c. In addition, in this thing, the description is abbreviate | omitted by attaching | subjecting the same code | symbol to the component same as what was demonstrated in other embodiment.
When the human sensor unit is housed in a U-shaped front panel as shown in FIG. 8, when the angle of the light receiving unit 1a is adjusted, the angle of the light receiving unit 1a is rotated to the full extent. Even if the tip of the piece 1c is brought into contact with the inner surface of the U-shaped front panel, the electric wire 5 is not sandwiched between the extended piece 1c and the inner surface of the U-shaped front panel, and is added to the electric wire 5. Stress can be reduced.

  The sensor element 3 according to the present invention may have any configuration as long as it is a human sensor mounted on a printed circuit board. That is, the sensor element 3 may be composed of a single semiconductor element, or may be composed of a semiconductor element and other electronic components and housed in a case, or other combinations.
