Embodiment 1 FIG.
FIG. 1 is a perspective view of lighting apparatus 1000 according to the present embodiment.
FIG. 2 is an exploded perspective view of lighting apparatus 1000 according to the present embodiment.

  As shown in FIG. 1, the lighting apparatus 1000 includes a lighting fixture 100 and two straight tubular lamps 200 (straight tube lamps) attached to the lighting fixture 100. The upper lamp 200 may be referred to as a lamp 200a, and the lower lamp 200 may be referred to as a lamp 200b.

As shown in FIG. 2, the lighting apparatus 100 includes a main body 110 (an apparatus main body) and a cover 150.
The main body 110 has a long shape, and is, for example, a rectangular box with one surface opened. When the main body 110 is attached to an attachment surface such as a ceiling surface or a wall surface, a portion that comes into contact with the attachment surface is referred to as an attachment plate 111.

  A lighting device 120, two pairs of lamp sockets 130 (130 a and 130 b), two human sensors 140 (140 c and 140 d), and a power terminal block 160 are attached to the main body 110. In addition, the mounting plate 111 is formed with a mounting hole 170 for mounting the main body 110 on the mounting surface, and a power supply hole 171 through which an electric wire connecting the power source (not shown) and the power terminal block 160 is passed.

The lighting device 120 is attached inside the main body 110. The lighting device 120 has a function of turning on or dimming the lamp 200 for a certain period when at least one of the two human sensors 140c and 140d detects a person.
The power terminal block 160 supplies power input from a power source (not shown) to the lighting device 120.

  Two lamp sockets 130 are installed at each end of the main body 110. The upper pair of lamp sockets 130 may be referred to as a lamp socket 130a, and the lower pair of lamp sockets 130 may be referred to as a lamp socket 130b. The lamp 200 is detachably attached to the lamp socket 130. The lamp 200a is detachably attached to the lamp socket 130a, and the lamp 200b is detachably attached to the lamp socket 130b.

Two human sensors 140 are attached to the attached plate 111 at a position between the two lamps 200 attached to the lamp socket 130 (see FIG. 1). The human sensor 140 is attached adjacent to the lamp 200 (see FIG. 1).
The human sensor 140 detects infrared rays (including infrared rays emitted from the human body), and determines that there is a person (a person's “present”) when detecting the movement of the detected infrared ray.
By disposing the human sensor 140 between the two lamps 200a and 200b so as to be adjacent to the lamp 200, the lighting apparatus 100 is not increased in size, and the lighting apparatus in which the human sensor 140 is not attached is provided. Almost the same outer shape can be obtained.

The cover 150 covers the attached plate 111 and is attached to the main body 110.
The cover 150 is a long plate material that closes the opening of the main body 110 so as to cover it. The cover 150 has a human sensor mounting opening 151 that exposes the human sensor 140 attached to the main body 110 and a lamp socket mounting opening 152 that exposes the lamp socket 130 also attached to the main body 110.
Further, a screw hole 154 for attaching the cover 150 to the main body 110 using the attachment screw 153 is provided on the side surface of the cover 150.

The two straight tubular lamps 200 are, for example, fluorescent lamps. Alternatively, the upper lamp 200a may be a straight tube LED lamp, and the lower lamp 200b may be a fluorescent lamp. Alternatively, both may be fluorescent lamps, or both may be straight tube LED lamps.
For example, when the lower lamp 200b is a fluorescent lamp, it can also serve as illumination for illuminating the feet.

FIG. 3 is a perspective view showing human sensor 140 attached to attached plate 111 of lighting apparatus 100 according to the present embodiment.
As shown in FIG. 3, the human sensor 140 includes a sensor base part 141 and a light receiving part 142.
The sensor base 141 is a plate formed so as to protrude from the mounted plate 111 of the main body 110, and includes a base upper surface part 143 on the light irradiation direction side. A light receiving unit 142 is installed on the table upper surface 143.

The light receiving unit 142 detects the presence / absence of a person by detecting heat and infrared rays. The light receiving unit 142 is installed so as to protrude further from the table top surface part 143.
The light receiving unit 142 is preferably arranged so as to protrude further in the light irradiation direction side than the lamp 200 when the lamp 200 is mounted on the lighting fixture 100. However, the light receiving unit 142 may be disposed on the same plane as the lamp 200.

The space portion 144 is a space generated between the table top surface portion 143 and the mounted plate 111.
As shown in FIGS. 2 and 3, a part of the lighting device 120 is inserted into the space 144. In this way, by placing the human sensor 140 on the mounted plate 111 while inserting a part of the lighting device 120 into the space 144, it is possible to prevent the main body 110 from becoming large.

Next, the arrangement of the human sensors 140c and 140d in the lighting fixture 100 according to the present embodiment will be described.
FIG. 4 is a schematic diagram for explaining the arrangement of human sensors 140c and 140d in lighting apparatus 1000 according to the present embodiment.

  The lamp 200, particularly in the case of a fluorescent lamp, has filaments at both ends, and heat and infrared rays are generated by heating the filament. Therefore, when the two human sensors 140c and 140d are disposed between the two lamps 200a and 200b and at both ends (points P4c and P4d) of the lamp 200 (in the case of FIG. 4A), the lamp Under the influence of heat and infrared rays emitted by 200, it becomes difficult to detect infrared rays emitted by humans. In such a case, for example, the heat and infrared rays generated by the lamp 200 may exceed the detection range detected by the human sensor 140, and the human sensor 140 may become saturated and human detection may not be possible. If the amount of infrared rays emitted from the lamp 200 fluctuates, the human sensor 140 may malfunction and keep the lamp 200 lit.

  However, as shown in FIG. 4B, by disposing the human sensor 140 at a position away from the both ends of the lamp 200 toward the point P0 (the center portion of the lamp 200), the heat and infrared rays generated by the lamp 200 are reduced. Impact is reduced.

As shown in FIG. 4, the center part of the length of the lighting fixture 100 in the longitudinal direction is P0, the end position (one end part) on the human sensor 140c (one human sensor) side is P4c, and the human sensor 140d ( An end position (the other end) on the other end side is defined as P4d. The center positions of P0 and P4c and P4d are P2c and P2d, respectively. The center positions of P2c and P4c and the center positions of P2d and P4d are P3c and P3d, respectively. Furthermore, the center position between P0 and P2c and the center position between P0 and P2d are P1c and P1d, respectively.
That is, P3c, P2c, P1c, P0, P1d, P2d, and P3d divide P4c to P4d into approximately eight equal parts.

In FIG.4 (b), the human sensitive sensors 140c and 140d are arrange | positioned at the center positions P2c and P2d of the center part P0 and the edge part positions P4c and P4d of the lighting fixture 100, respectively.
For example, the human sensors 140c and 140d may be arranged at P3c and P3d, respectively. In this case, the human sensors 140 c and 140 d are closer to the end of the lamp 200. Therefore, it is more desirable to arrange the human sensors 140c and 140d between P3c and P2c and between P3d and P2d, respectively.

  For example, the human sensors 140c and 140d may be arranged at P1c and P1d, respectively. In this case, the human sensors 140c and 140d are closer to the central portion P0 of the lamp 200. Therefore, it is more desirable to arrange the human sensors 140c and 140d between P1c and P2c and between P1d and P2d, respectively.

  For example, it is desirable to arrange the human sensors 140c and 140d between P1c and P3c and between P1d and P3d, respectively. That is, the human sensor 140c is arranged in a range of a quarter of the distance between P0 and P4c (between P1c and P3c) using P2c as a reference, and the human sensor 140d is used as P0 using P2d as a reference. And P4d are preferably arranged in a quarter range (between P1d and P3d).

  In this manner, by arranging the human sensors 140 in both end directions with the central portion P0 of the lamp 200 as a boundary, for example, when the lighting device 1000 is installed at a landing of a staircase, the ascending or descending side of the stairs Any of these can detect people.

The above-described arrangement method of the human sensors 140c and 140d is arranged at a symmetric position with respect to the central position P0 of the luminaire 100, but may not necessarily be symmetric.
For example, the human sensor 140c may be disposed near P3c, and the human sensor 140d may be disposed near P2d. Alternatively, the human sensor 140c may be arranged near P1c, and the human sensor 140d may be arranged near P3d. Or the reverse of these may be sufficient.
In this way, by arranging the human sensors 140c and 140d asymmetrically with respect to the central position P0, it is possible to cope with steps having different widths on the ascending side and the descending side.

As described above, according to the luminaire 100 according to the present embodiment, the two human sensors are arranged between the two lamps and at respective positions with the center in the longitudinal direction of the linear lamp as a boundary. Therefore, it is not necessary to increase the size of the lighting fixture.
Further, since the space portion 144 is provided between the base surface portion 143 of the human sensor 140 and the mounted plate 111 of the main body 110, and the lighting device 120 can be inserted into the space portion 144, the size of the lighting fixture can be increased. There is no need to increase the size.
In addition, since the two human sensors are arranged closer to the center than the end of the lamp, the sensitivity of the human sensor to detect a person is reduced due to the heat and infrared rays of the filament of the lamp (fluorescent lamp). There is no.
