  However, in Patent Document 1 and Patent Document 2, since the human sensor and the lighting fixture are integrally attached, the human detection range of the human sensor is limited, and the staircase space is a complicated shape space. If this is the case, it may not be possible to detect people in all areas of the staircase space. Even if there is a person in the staircase space, if the human sensor cannot detect the person, the lighting apparatus cannot be properly turned on.

  An object of the present invention is to provide a lighting device that can detect a person in a wide area of a staircase and appropriately turn on a lighting fixture even when the staircase is a complicated shape space. That is.

  A lighting device according to a first aspect of the present invention is a human sensor that is installed in any part of a staircase and detects the presence of a person in a predetermined region of the staircase by supplying power from a dedicated power line. When power is supplied from a power line formed by a system different from the power line of the human sensor, and is installed at a position different from the human sensor and the human sensor detects the presence of a person Comprises a lighting device connected to a human sensor so as to light a predetermined area where a person exists with a predetermined brightness.

  In the present invention and the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

  A staircase space is a staircase, staircase, stair landing, etc., and any part of a staircase space is an object that forms a staircase space, such as a ceiling, wall, floor, or handrail This is a good place to detect the presence. The human sensor is, for example, an infrared sensor, and the predetermined area in which the human sensor detects the presence of a person is a predetermined angular range and a predetermined distance range in the vertical and horizontal directions from the installation location of the human sensor. is there. The predetermined angular range in the vertical direction is, for example, about 80 °, the angular range in the horizontal direction is, for example, about 50 °, and the predetermined distance range is, for example, 10 m. Further, in the vertical direction, it is possible to use a vertical direction variable.

  The power line of the human sensor is a power line that supplies power necessary for the operation of the human sensor, and is usually a power line drawn from a commercial power source.

  “Installed at a position different from the human sensor” means that the human sensor and the lighting fixture are not integrated but are configured separately and installed at different positions in the staircase space. The human sensor is installed at a position where it is easy to detect the presence of a person, and the luminaire is installed at a position where an area where the person exists can be appropriately illuminated.

  Lighting with a predetermined brightness means, for example, turning on 100% of a lighting fixture. When no person is present, the lights are turned off or the lighting equipment is turned on at 25%, and when the presence of a person is detected, the lighting equipment is turned on at 100%.

  The power line of the luminaire is a power line that supplies power necessary for lighting the luminaire, and is usually a power line drawn from a commercial power source. “It is formed by a system different from the human sensor power line” means that the human sensor power line and the lighting apparatus power line are drawn independently from the commercial power source, or the lighting apparatus or human sensor. Commercial power is separately supplied by the feed wiring.

  A lighting device according to a second aspect of the present invention is the lighting device according to the first aspect, wherein the human sensor includes a power switch for turning on and off the power supplied from the power line of the human sensor. .

  The power switch provided in the human sensor turns on / off the power necessary for the operation of the human sensor supplied to the human sensor. As a result, only the human sensor can be turned on / off independently of the lighting fixture.

  According to the first aspect of the present invention, since the human sensor and the lighting fixture are configured separately and are installed at different positions in the staircase space, the human sensor can be installed at a position where it is easy to detect the presence of a person. The lighting apparatus can be installed at a position where an area where a person exists can be appropriately illuminated. Therefore, even if the staircase space is a complicated shape space, a person can be detected in a wide area of the staircase space, and illumination with a lighting fixture can be performed appropriately.

  According to the invention of claim 2, since the power switch for turning on / off the power supplied from the power line of the human sensor is provided, it becomes possible to turn on / off only the human sensor independently of the lighting fixture. According to the use situation or installation situation of the lighting fixture, the lighting fixture can be easily controlled independently from the human sensor.

  FIG. 1 is a block diagram showing an example of a lighting device according to an embodiment of the present invention. In FIG. 1, a human sensor 11 for detecting the presence of a person is installed in a staircase space. That is, it is installed on a ceiling surface, a wall surface, a floor surface, a handrail or the like of a staircase, a staircase, a stair landing, or the like. The human sensor 11 includes a human sensor main unit 11a and a human sensor child unit 11b. The human sensor sub unit 11b is connected to the human sensor main unit 11a via a signal line 12. Although FIG. 1 shows the case where there is one human sensor slave unit 11b, a plurality of human sensor sub units 11b may be provided.

  The human sensor main unit 11a and the human sensor sub unit 11b each detect the presence of a person in a predetermined area of the staircase space that the human sensor 11a and 11b detect. It is transmitted to the human sensor main unit 11a via the line 12. The human sensor main unit 11a outputs a lighting command to the lighting device 14 via the signal line 13 when either the own detection signal or the human sensor sub unit 11b detects the presence of a person.

  In addition, power is supplied to the human sensor main unit 11a from, for example, a commercial power supply 15 through a power sensor power line 16, and the human sensor 11b is also supplied to the human sensor 11b from the human sensor main unit 11a. Power is supplied through the sensor power line 16.

  On the other hand, the luminaire 14 is arranged at a position suitable for illuminating the staircase space, and is turned on by a human presence detection signal obtained from the human sensor main unit 11 a via the signal line 13. And the power supply for lighting fixtures of the lighting fixture 14 is supplied to the lighting fixture 14 from the commercial power supply 15 via the power supply line 17 of a lighting fixture, for example. As described above, the power to the human sensor 11 and the lighting fixture 14 is supplied from the commercial power supply 15 in a separate system. Moreover, since the human sensor 11 and the lighting fixture 14 are not integrated and are formed separately, the human detection sensor 11 is arranged at a desired position in the staircase space without being limited to the arrangement position of the lighting fixture 14. Is possible.

  FIG. 2 is a block diagram showing another example of the illumination device according to the embodiment of the present invention. In FIG. 2, the power line 16 of the human sensor is connected to the human sensor main unit 11a via the lighting fixture 14, and the human sensor power line is further connected from the human sensor main unit 11a to the human sensor slave unit 11b. 16 is connected, and power is supplied from the commercial power supply 15 to the human sensor main unit 11a and the human sensor sub unit 11b. In this way, when the human sensor power is supplied from the commercial power source 15 to the human sensor 11 via the lighting fixture 14, the wiring work can be performed together with the wiring of the signal line 13, as will be described later. , Workability is improved.

  FIG. 3 is a partially cutaway perspective view when the lighting device according to the embodiment of the present invention is installed in a staircase space. FIG. 3 shows a case where a lighting device is attached to the wall surface of the stair landing.

  As shown in FIG. 3, the lighting fixture 14 is installed on a wall surface 18 a that forms a staircase space, and the human sensor base unit 11 a is arranged on the same wall surface 18 a as the lighting fixture 14. On the other hand, the human sensor slave unit 11b is arranged on a wall surface 18b different from the wall surface 18a on which the human sensor main unit 11a and the lighting fixture 14 are arranged.

  Further, the signal line 12 for connecting the human sensor main unit 11a and the human sensor sub unit 11b, the signal line 13 for the human sensor main unit 11a for connecting the lighting fixture 14, and the power source of the human sensor. The line 16 and the power supply line 17 of the lighting fixture are shown in the case where they are wired on the wall surfaces 18 a and 18 b and covered with the wiring cover 19.

  In this way, the human sensor 11 and the lighting device 14 are not integrated but formed separately, and the human sensor main unit 11a and the human sensor child device 11b are formed separately, respectively. The human sensor main unit 11a and the human sensor slave unit 11b can be arranged at a desired position without being limited by the arrangement position of 14. In FIG. 3, the human sensor main unit 11 a detects whether or not a person exists mainly on the stairs and landing on the right front side, and the human sensor slave unit 11 b mainly detects a person on the left stairs and landing. Whether it exists or not is detected. In this case, the human sensor main unit 11a and the human sensor slave unit 11b are not integral with the lighting fixture 14, but are separate from each other, and can be arranged in the detection direction. Therefore, even if the staircase space has a complicated shape, the human sensor main unit 11a and the human sensor sub unit 11b can be appropriately installed in the region where the presence of a person is detected.

  In FIG. 3, the wiring processing on the side of the human sensor slave unit 11 b shows a case where wiring is performed on the wall surfaces 18 a and 18 b and covered with the wiring cover 19, but wiring can also be performed on the wall surfaces 18 a and 18 b. In this case, since it is not necessary to arrange the wiring cover 19 exposed, even if the human sensor slave unit 11b is arranged away from the lighting fixture 14, the design is not deteriorated.

  FIG. 4 is a perspective view of the human sensor base unit 11a. A sensor unit 21 for detecting the presence of a person is provided on the front portion (upper surface direction in FIG. 4) of the human sensor main body 20. For example, in the case of an infrared sensor, infrared rays are transmitted from the sensor unit 21 and the presence of a person is detected by receiving the reflected infrared ray. In this case, the human sensor base unit 11a detects the presence of a person using a predetermined area as a detection area from the installation location. For example, in the case of an infrared sensor, as a predetermined area for detecting the presence of a person, the predetermined distance range from the installation location of the human sensor main unit 11a is, for example, 10 m, and the vertical angle range is, for example, about 80 °, horizontal The angular range of the direction is, for example, about 50 °. When a person is present in this area, a detection signal indicating that a person is present is output.

  In addition, a power switch 22 for turning on / off the power supplied from the power line of the human sensor is provided around the front part of the human sensor main body 20 to which the sensor unit 21 is attached (front direction in FIG. 4). It has been. The power switch 22 turns on / off the power necessary for the operation of the human sensor main unit 11a independently of the power to the lighting fixture 14. For example, by turning off the power switch 22 in a daytime time zone when there are many people passing by and the lighting device 14 is unsatisfactory, unnecessary lighting in the daytime time zone can be omitted, which can contribute to energy saving. Further, even when it is desired to keep the lighting fixture 14 in a constantly lit state, the lighting state can be maintained by turning off the human sensor 11 while the lighting fixture 14 is lit up. It is possible to cope with a relatively large number of cases where it is not desired to frequently switch illumination. In the present embodiment, the power switch 22 is provided in the periphery of the human sensor main body 20, and the power switch 22 is unlikely to be mistakenly operated when the human sensor 20 is attached to a wall surface or the like. It is like that.

  Next, FIG. 5 is a perspective view of the lighting fixture 14 and the wiring cover 19. In FIG. 5, a notch hole 23 for passing the signal line 13 and the power line 16 of the human sensor is provided at an end portion of the lighting fixture 14, and a connection mounting bracket 24 is fixed to the fixing bracket 25 above the notch hole 23. It is fixed by. The connection mounting bracket 24 is connected to the fixing bracket 25 by inserting the protruding portion of the connection mounting bracket 24 into the engaging portion of the fixing bracket 25. Thereby, it can connect, without using a screw | thread etc. Further, the human sensor main unit 11a or the human sensor sub unit 11b is attached to the distal end portion of the connection mounting bracket 24. And the wiring cover 19 is attached between the lighting fixture 14 and the human sensor main unit 11a or the human sensor sub unit 11b.

  The wiring cover 19 is formed of an insulating material, has a cut groove 26 for being held by the connection mounting bracket 24, and has a partition wall 27 for partitioning the inside. Then, by passing the connection fitting 24 through the cut groove 26, two passages are formed through which the signal lines 12 and 13 and the power line 16 of the human sensor are passed.

  FIG. 6 is a side view of the luminaire 14 and the human sensor main unit 11a connected by the connection mounting bracket 24. FIG. The human sensor main unit 11a is attached to the tip of the connection mounting bracket 24, and the wiring cover 19 is mounted on the connection mounting bracket 24 between the lighting fixture 14 and the human sensor main unit 11a. As described above, the wiring cover 19 has two passages formed by the partition walls 27. The signal lines 12 and 13 are passed through one passage, and the power supply line 16 of the human sensor is passed through the other passage.

  As a result, in the lead-in connection of the power line and the signal line, the wiring path can be formed without satisfying the requirements of Article 189 of the Electrical Equipment Technical Standards Chapter 5 and without using screws or the like. Will improve. Moreover, since the lighting fixture 14 arrange | positioned separately and the human sensitive sensor main | base station 11a (human sensitive sensor subunit | mobile_unit 11b) can be integrated by adjusting the length and direction of the connection attachment bracket 24, it is workability. Will improve.

  Here, when the distance between the luminaire 14 and the human sensor 11 is increased, the connection fitting 24 that connects the luminaire 14 and the human sensor 11 also becomes long, and the human sensor 11 and the connection fitting 24 itself. The connection mounting bracket 24 may bend and sag due to the load. Therefore, an inclined surface for preventing the connection fitting 24 from hanging down is provided at a portion where the connection fitting 24 is fixed to the lighting fixture 14. This prevents the connection fitting 24 from hanging down.

  As described above, according to the embodiment of the present invention, the human sensor 11 and the lighting fixture 14 are not integrated and are formed separately, so that the position of the lighting fixture 14 is not limited, The human sensor 11 can be disposed at a desired position in the staircase space. Therefore, even if the staircase space has a complicated shape, the human sensor main unit 11a and the human sensor sub unit 11b can be appropriately installed in the region where the presence of a person is detected. In addition, since the power switch 22 for turning on and off the power necessary for the operation of the human sensor main unit 11a independently of the power to the lighting fixture 14 is provided, it is possible to omit unnecessary lighting during the daytime period. And contribute to energy saving.
