[5. Sensor device 5]
The sensor device 5 detects the presence of a person as a surrounding condition. For example, the sensor device 5 is a radio wave sensor that utilizes the Doppler effect. The sensor device 5 transmits unmodulated continuous wave radio waves (transmission waves) in the microwave band (24 GHz band) from a transmitting antenna, and receives radio waves reflected by an object (reflected waves) using a receiving antenna. When a transmitted wave is reflected by a moving object, a frequency difference occurs between the transmitted wave and the reflected wave depending on the moving speed of the moving object due to the Doppler effect. The sensor device 5 detects the presence of a moving object (mainly a person going up and down the stairs, but also includes a stairway door opened and closed by a person) based on the frequency difference. The sensor device 5 outputs a detection signal to the control device 60 while detecting the presence of a moving object. However, the sensor device 5 transmits a frequency-modulated transmission wave from the transmission antenna, multiplies the reception wave received by the reception antenna by the transmission wave, and performs phase detection to calculate the distance to the object that reflected the transmission wave. The presence of a person may be detected by distance measurement.

The sensor device 5 includes a sensor circuit including a transmitting antenna, a receiving antenna, and a signal processing circuit, and an outer shell 50 that houses the sensor circuit (see FIGS. 3, 4, and 10). The sensor circuit is composed of a printed circuit in which a transmitting antenna, a receiving antenna, and a signal processing circuit are mounted on a single printed wiring board. The outer shell 50 is made of a synthetic resin material such as polystyrene, polypropylene, ABS (acrylonitrile butadiene styrene), etc., and has a rectangular parallelepiped shape. The sensor circuit is housed within the outer shell 50 so that the transmitting antenna and the receiving antenna are opposed to a first bottom surface (front surface) 501 of the outer shell 50 . That is, the radio waves transmitted from the transmitting antenna are radiated through the first bottom surface 501 of the outer shell 50. Similarly, radio waves reflected by an object (reflected waves) are received by the receiving antenna through the first bottom surface 501 of the outer shell 50.

A mounting base 51 is attached to the second bottom surface (rear surface) 502 of the outer shell 50 (see FIG. 10). The mounting base 51 includes a first plate 511 fixed to the inner bottom surface of the instrument body 1 (front surface of the back plate 10), a second plate 512 protruding forward from the lower end of the first plate 511, and a second plate 512. It has a third plate 513 that projects obliquely upward from the front end. The first plate 511, the second plate 512, and the third plate 513 are each formed into a rectangular flat plate shape. However, the first plate 511, the second plate 512, and the third plate 513 are integrally formed by bending a single metal plate.

The outer shell 50 is attached to the front surface of the third plate 513. Here, the third plate 513 is inclined forward by a predetermined inclination angle θ with respect to the first plate 511 (see FIG. 10). Therefore, when the appliance main body 1 is installed on the wall of the staircase, the front surface of the sensor device 5 (first bottom surface 501 of the outer shell 50) is tilted downward by the inclination angle θ with respect to the normal direction (horizontal direction) of the wall surface. It will be tilted. Note that this inclination angle is preferably about 23° to 24°, for example.

The sensor device 5 is housed in the center of the instrument body 1 in the longitudinal direction (horizontal direction). Specifically, the first plate 511 of the mounting base 51 is fixed on the emergency light source unit 4 on the front surface of the back plate 10 (see FIG. 10). The front end portion of the sensor device 5 projects forward of the mounting portion 320 through the window hole 322 of the mounting plate 32 of the common light source unit 3. That is, the sensor device 5 can transmit and receive radio waves through the cover 2 without being obstructed by the metal mounting plate 32.

[6. Emergency power supply 7]
The emergency power source 7 includes, for example, a plurality of storage batteries and a battery case 70 that accommodates the plurality of storage batteries (see FIG. 3). Each of the plurality of storage batteries is, for example, a dry cell type nickel-metal hydride storage battery. The battery case 70 is formed into a cylindrical shape and made of an electrically insulating material such as synthetic resin. The emergency power supply 7 is housed, for example, at the left end of the instrument main body 1 (see FIG. 3).

[7. Switch block 8]
The switch block 8 is configured by accommodating a circuit board in a housing 80 made of synthetic resin (see FIG. 3). Two push button switches, a monitor lamp, an infrared light receiving element, etc. are mounted on the circuit board. The monitor lamp has, for example, an LED chip that emits green light. The infrared light receiving element is configured to receive (receive) a control signal using infrared rays as a communication medium, and demodulate a transmission frame from the received control signal. This control signal is transmitted from a remote controller operated by a worker who performs periodic inspection work.

The housing 80 is made of synthetic resin material and has a box shape. Four holes are opened in the lower surface of the housing 80. One operating member 81 is fitted into two of these four holes. These two operating members 81 are supported by the housing 80 so that they can be pushed into the lower surface of the housing 80. Therefore, when one operating member 81 is pushed in, one push button switch is turned on, and when the other operating member 81 is pushed in, the other push button switch is turned on. Furthermore, a monitor lamp and an infrared light receiving element face each other one-to-one in the remaining two holes. That is, the green light emitted from the monitor lamp is emitted to the outside of the housing 80 through one of the holes. Further, a control signal transmitted from the remote controller is received (received) by the infrared light receiving element through the other hole.

The switch block 8 is housed on the right side of the emergency power source 7 within the instrument body 1. However, the switch block 8 exposes the lower surface of the housing 80 (two operating members 81 and two holes) to the outside of the instrument body 1 through the second window 122 of the lower plate 12 (see FIG. 2C).

[8. Circuit block 6]
As shown in FIG. 11, the circuit block 6 includes a control device 60, a charging device 61, and an emergency lighting device 62. The charging device 61 converts regular power (AC power) supplied from a regular power source PS such as a grid power source into DC power, and charges the emergency power source 7 with the converted DC power. The emergency lighting device 62 lights the two second LED modules 40 of the emergency light source unit 4 with emergency power (DC power) supplied from the emergency power supply 7 via the charging device 61 according to instructions from the control device 60 . Turn it on.

The control device 60 includes, for example, a microcontroller. The control device 60 determines whether or not the regular power supply PS is out of power by dividing and detecting the voltage input to the regular lighting device 33 using two resistors R1 and R2. If the control device 60 determines that the regular power source PS is not out of power, it causes the charging device 61 to charge the emergency power source 7, and causes the regular lighting device 33 to light up the two first LED modules 30 of the regular light source unit 3. let Further, the control device 60 lights up the monitor lamp of the switch block 8 while the charging device 61 is charging the emergency power source 7 . On the other hand, if the control device 60 determines that the regular power source PS is out of power, it causes the charging device 61 to stop charging the emergency power source 7, and causes the emergency lighting device 62 to switch on the two emergency light source units 4. The second LED module 40 is turned on.

Further, when the detection signal is not input from the sensor device 5, the control device 60 controls the regular lighting device 33 to make the current supplied to the two first LED modules 30 approximately half of the rated value. On the other hand, when the detection signal is input from the sensor device 5, the control device 60 controls the regular lighting device 33 to set the current supplied to the two first LED modules 30 to the rated value. Note that the control device 60 controls the regular lighting device 33 to maintain the current supplied to the two first LED modules 30 at the rated value until a predetermined time has elapsed from the time when the detection signal is no longer input from the sensor device 5. It is preferable to do so.

Furthermore, when either of the two pushbutton switches of the switch block 8 is turned on, the control device 60 causes the charging device 61 to stop charging the emergency power source 7, and causes the emergency lighting device 62 to stop charging the emergency light source unit. The two second LED modules 40 of No. 4 are turned on. However, the control device 60 causes the emergency lighting device 62 to light up the two second LED modules 40 of the emergency light source unit 4 only while one of the push button switches is on. The control device 60 starts self-inspection when the other push button switch is turned on, and lights the two second LEDs of the emergency light source unit 4 in the emergency lighting device 62 until a predetermined period of time (30 minutes or 60 minutes) has elapsed. The module 40 is turned on. Note that the control device 60 also starts the self-inspection when the infrared light receiving element of the switch block 8 receives a control signal.

The circuit block 6 has a metal case 63 (see FIG. 3). A printed circuit board is housed within the case 63. The printed circuit board constitutes a control device 60, a charging device 61, and an emergency lighting device 62. The circuit block 6 is housed on the left side of the emergency light source unit 4 in the instrument body 1 (see FIG. 3). The case 63 of the circuit block 6 is preferably fixed to the lower surface of the upper plate 11 of the instrument body 1 by screwing. However, the case 63 of the circuit block 6 may be fixed to the back plate 10 or the lower plate 12.

[9. Installation procedure of lighting fixture X1]
The lighting fixture X1 configured as described above is installed on the wall of the landing according to the procedure described below.

First, a worker who performs the installation work attaches the appliance main body 1 from which the regular light source unit 3 has been removed to the wall. That is, the operator passes two anchor bolts embedded in the wall through the elongated holes 101 of the instrument body 1, and tightens nuts on these two anchor bolts to fix the instrument body 1 to the wall. Then, the operator electrically connects the power wire inserted through the round hole 100 of the device main body 1 to the primary side terminal of the terminal block 14.

Subsequently, the operator attaches the regular light source unit 3 to the instrument main body 1. That is, the worker electrically connects the input terminal of the regular lighting device 33 of the regular light source unit 3 and the secondary side terminal of the terminal block 14 with an electric wire. Then, the operator hooks the hook pieces 340 of the two hook fittings 34 of the regular light source unit 3 onto the frame portions 130 of the two receiving metal fittings 13 of the fixture main body 1, respectively, and attaches the regular light source to the front of the fixture main body 1. Install unit 3. At this time, the front opening of the instrument body 1 is closed by the cover body 20 of the cover 2 (see FIGS. 1 and 2A). Further, the openings at both longitudinal ends of the instrument main body 1 are each closed by a pair of protruding walls 21 of the cover 2 (see FIGS. 2B and 2C).

The lighting fixture X1 is installed on the wall by the above procedure. Here, in order to improve the workability of construction, the lighting fixture X1 adopts a structure in which the mounting plate 32 on which the two first LED modules 30 are attached is detachably separated from the fixture body 1 that is attached to the wall. ing. However, when the common light source unit 3 is attached to the appliance body 1, the mounting plate 32 of the common light source unit 3 can be considered to constitute the appliance body 1 together with the back plate 10, the upper plate 11, and the lower plate 12. Furthermore, the left side wall 203 and right side wall 204 of the cover 2, which closes the openings at both longitudinal ends of the appliance body 1, which is made up of the back plate 10, the upper side plate 11, the lower side plate 12, and the mounting plate 32, are also considered to constitute the appliance body 1. I can do it. In other words, the device body 1 is considered to be formed into a long box shape by the back plate 10, the upper plate 11, the lower plate 12, the mounting plate 32, the left side wall 203 of the cover 2, and the right side wall 204 of the cover 2. It's okay.

[10. Features of lighting fixture X1 according to Embodiment 1]
Hereinafter, the characteristics of the lighting fixture X1 will be explained in more detail.

In the conventional example, the human detection unit and the two emergency light source units are exposed outside the fixture body, making the entire lighting fixture slimmer (shorter width dimension in the transverse direction) and shorter (longitudinal direction). It was difficult to shorten the length dimension.

On the other hand, the lighting fixture X1 houses the sensor device 5, the regular light source unit 3, and the emergency light source unit 4 in the fixture body 1 (see FIGS. 1 to 4). In other words, in the lighting fixture X1, the emergency light source unit 4 and the sensor device 5 are housed together in the fixture body 1 that houses the regular light source unit 3, so the lighting fixture X1 as a whole can be made slimmer and more compact than the conventional example. It is possible to shorten the time. Furthermore, the lighting fixture X1 is further slimmed down by arranging the two first LED modules 30 and the sensor device 5 in a row, and arranging the sensor device 5 at a position sandwiched between the two first LED modules 30. ing. Furthermore, in the lighting fixture X1, a cover 2 is attached to the front surface of the fixture body 1 so as to cover the regular light source unit 3, the emergency light source unit 4, and the sensor device 5 when viewed from the front of the fixture body 1. In other words, the appearance of the lighting fixture X1 can be improved by covering the regular light source unit 3, the emergency light source unit 4, and the sensor device 5 with the cover 2. Furthermore, in the lighting fixture X1, the fixture body 1 and the cover 2 cover the regular light source unit 3, the emergency light source unit 4, and the sensor device 5 when viewed from the side (left-right direction) of the fixture body 1. In other words, the lighting fixture X1 can improve its appearance when viewed from the side. Note that in the lighting fixture X1, the lower surface of the lower plate 12 of the fixture main body 1 and the lower surface of the panel 46 are approximately on the same plane, but a portion of the panel 46 may protrude slightly from the lower surface of the lower plate 12. do not have.

By the way, the outer shell 50 of the sensor device 5 is attached to the instrument main body 1 so as to be inclined downward by an inclination angle θ with respect to the horizontal direction. Therefore, a space (dead space) S2 is created between the lower surface of the outer shell 50 and the lower plate 12 of the instrument main body 1 (see FIG. 10). Therefore, in the lighting fixture X1, the emergency light source unit 4 is arranged in the space S2. That is, in the lighting fixture X1, by arranging the emergency light source unit 4 in the dead space (space S2) that occurs within the fixture body 1, the fixture body 1 can be further slimmed down.

Moreover, the emergency light source unit 4 is configured to emit light in a line shape using the two second LED modules 40 and the light guide 43. In other words, the emergency light source unit 4 distributes illumination light in the left-right direction of the fixture body 1 without using a dome-shaped lens like conventional emergency light source units, thereby making the fixture body 1 even slimmer. It is possible to aim for

Furthermore, the illumination light emitted from the light guide 43 is radiated to the outside of the instrument main body 1 through a first window 121 provided in the lower plate 12 of the instrument main body 1. This first window 121 is covered with a translucent panel 46. In other words, by covering the first window 121 from which light is emitted with the panel 46, foreign objects such as insects can be prevented from entering the instrument body 1. In the lighting equipment X1, if the panel 46 is made of a noncombustible material, in the event of a fire, the emergency light source unit 4 is protected by the panel 46 together with the metal equipment main body 1, and the emergency light source unit 4 is protected for a predetermined period of time (30 minutes or 60 minutes). ) Emergency lighting can be secured.

Here, the first window 121 is arranged behind the front end of the sensor device 5 (the lower side of the first bottom surface 501 of the outer shell 50) in the front-rear direction of the instrument main body 1 (see FIG. 10). In other words, the position of the first window 121 is related to the position of the light guide 43, and when the first window 121 is positioned forward of the front end of the sensor device 5, a space for accommodating the light guide 43 is secured. Therefore, it is necessary to increase the distance between the sensor device 5 and the lower plate 12. Therefore, the lighting fixture X1 can also be made slimmer by arranging the first window 121 behind the front end of the sensor device 5.

The tip of the screw 325 protrudes to the outside of the attachment piece 324 (the side away from the window hole 322 of the attachment part 320) along the longitudinal direction of the attachment part 320. Note that the pair of attachment pieces 324 are each formed separately from the attachment portion 320 and screwed to the attachment portion 320. However, each of the pair of attachment pieces 324 may be formed integrally with the attachment portion 320.

[11-4. Regular lighting device 33]
The regular lighting device 33 is common to the regular lighting device 33 of the lighting fixture X1 according to the first embodiment. The regular lighting device 33 is attached to the rear surface of the attachment part 320 (see FIGS. 16 to 18).

[11-5. Assembly of regular light source unit 3]
The two first LED modules 30 and the two lens blocks 31 are each attached to the front surface of the attachment part 320 of the attachment plate 32. One fixing screw 315 is inserted into each of the plurality of screw insertion holes 3102 provided in the base portion 310 of the lens block 31 (see FIGS. 15 and 19). The lens block 31 is fixed to the mounting part 320 by screwing each of the plurality of fixing screws 315 into a plurality of screw holes provided in the base part 310 one by one. On the other hand, the first LED module 30 is attached to the attachment part 320 by being sandwiched between the attachment part 320 and the base part 310 of the lens block 31 when the lens block 31 is fixed to the attachment part 320 (see FIG. 19).

Here, the four LEDs 301A, 301B, 301C, and 301D mounted on the first end 3001 of the substrate 300 overlap the first lens 312 of the lens block 31 when viewed from the front (see FIG. 19). Furthermore, the four LEDs 301 mounted on the second end 3002 of the substrate 300 overlap the second lens 313 of the lens block 31 when viewed from the front (see FIG. 15).

The mounting base 52 includes a box body 521 with an open front surface, and a pair of fixing protrusions 522 protruding from the left and right side surfaces of the box body 521. A pair of holes 5210 penetrate through the bottom wall of the box body 521 (see FIGS. 16 and 18). The outer shell 50 of the sensor device 5 includes a pair of hook pieces 523 that protrude rearward from the rear end of the outer shell 50.

Thus, the sensor device 5 can be mounted by inserting the pair of hook pieces 523 of the outer shell 50 into the pair of holes in the bottom wall of the mounting base 52 one by one, and hooking the hook pieces 523 on the edges of the holes in the bottom wall. It is attached to the bottom wall of the stand 52 (see FIGS. 16 and 18).

The mounting base 52 is attached to the mounting plate 32 by screwing a pair of fixing protrusions 522 to the mounting portion 320 of the mounting plate 32 (see FIG. 18). Note that the pair of fixing protrusions 522 are each screwed to the left and right sides of the window hole 322 on the rear surface of the mounting portion 320. Therefore, the sensor device 5 attached to the mounting base 52 causes the front end portion of the outer shell 50 to protrude forward of the mounting portion 320 through the window hole 322 of the mounting plate 32 (see FIGS. 13 and 15). As a result, the sensor device 5 can transmit and receive radio waves without being obstructed by the metal mounting plate 32. Further, the front surface of the sensor device 5 is attached to the attachment portion 320 so as to be inclined downward by an inclination angle with respect to the normal direction (horizontal direction) of the wall surface.

The cover main body 20 has a front wall 200, an upper wall 201, and a lower wall 202, and is formed in the shape of an elongated square horn with an open rear surface and both left and right sides. The front wall 200 is formed into a long rectangular shape whose longitudinal direction is the left-right direction. The upper wall 201 is formed in a long rectangular shape and protrudes rearward from the upper end of the front wall 200 in the longitudinal direction. The lower wall 202 is formed in a long rectangular shape and protrudes rearward from the lower end of the front wall 200 in the longitudinal direction. The cover main body 20 is made of a molded body of synthetic resin (for example, polycarbonate resin or acrylic resin) having translucency.

Three elongated screw insertion holes 205 are provided at each of the rear ends of the upper wall 201 and the lower wall 202 of the cover body 20 (see FIG. 13). One mounting screw 23 is inserted into each of these screw insertion holes 205. Then, the cover body 20 is attached to the attachment plate 32 by screwing one attachment screw 23 into a plurality of screw holes 3210 provided in each of the pair of fixing pieces 321 (see FIG. 14). When the cover main body 20 is attached to the mounting plate 32, the rear surface of the cover main body 20 is closed by the mounting plate 32.

The pair of cover ends 22 are each formed to have the same shape and dimensions. As shown in FIG. 20, the cover end 22 includes a cover end main body 220, a side wall 221, a first hook portion 222, and a second hook portion 223. Note that the cover end body 220, the side wall 221, the first hook portion 222, and the second hook portion 223 are preferably formed integrally as a molded body of synthetic resin having a light reflectance of 90% or more, for example.

The cover end main body 220 is formed into a rectangular flat plate shape. The side wall 221 projects laterally from two long sides (upper end and lower end) and one short side (front end) of the cover end main body 220.

The first hook portion 222 has a horizontal piece 2220 and a vertical piece 2221. The horizontal piece 2220 and the vertical piece 2221 are each formed in a rectangular flat plate shape with equal lengths in the longitudinal direction. The horizontal piece 2220 protrudes from the center of the inner bottom surface of the cover end main body 220 so as to be parallel to the side walls 221 at the upper and lower ends. The vertical piece 2221 protrudes from the tip of the horizontal piece 2220 on both sides of the upper and lower sides of the horizontal piece 2220. Thus, the first hook portion 222 is formed in a T-shape when viewed from the longitudinal direction (back and forth direction) of the cover end main body 220.

Each of the pair of second hook portions 223 is formed in an elongated trapezoidal shape. The pair of second hook portions 223 protrude from the inner bottom surface of the cover end main body 220 so as to face each other with the first hook portion 222 in between. Each first hook portion 222 has an inclined portion 2230 that slopes so as to gradually increase the amount of protrusion from the inner bottom surface of the cover end body 220 from the rear end to the front end of the cover end body 220. Further, each first hook portion 222 has a semicircular recess 2231 in front of the inclined portion 2230. Furthermore, a protrusion 2232 that protrudes in the thickness direction (left-right direction) of the cover end main body 220 is provided at the front end portion of each first hook 222 .

These pair of cover ends 22 are configured to be detachably attached to the instrument main body 1 and close both left and right side surfaces of the cover main body 20 (see FIG. 12C), as will be described later. The illumination light emitted from the two first LED modules 30 passes through the cover main body 20 and is irradiated onto a space (a landing, a staircase, etc. of a staircase). However, a part of the illumination light emitted from the two first LED modules 30 is reflected by the pair of cover ends 22 and then transmitted through the cover body 20 and irradiated into the space.

[14. Instrument body 1]
The instrument main body 1 has a first instrument main body 16 and a second instrument main body 17, as shown in FIG. The second instrument main body 17 is detachably coupled to the first instrument main body 16. The first instrument main body 16 and the second instrument main body 17 are combined to form an elongated box-shaped instrument main body 1 with an open front.

[14-1. First instrument body 16]
The first instrument main body 16 has a back plate 160, a bottom plate 161, and a pair of support plates 162 (see FIG. 13). However, the back plate 160, the bottom plate 161, and the pair of support plates 162 are integrally formed by bending a single metal plate. The back plate 160 and the bottom plate 161 are each formed into a long rectangular flat plate having the same length. The bottom plate 161 projects forward from one end (lower end) of the back plate 160 along the longitudinal direction. Further, a reinforcing piece 1610 projects forward from the other end (upper end) of the back plate 160 along the longitudinal direction. However, the length of the reinforcing piece 1610 is shorter than the length of the back plate 160. That is, the reinforcing piece 1610 is not provided at the left end of the upper end of the back plate 160 (see FIG. 13).

Each support plate 162 is formed into a rectangular flat plate shape. Each support plate 162 has a first groove 1621, a second groove 1622, and a third groove 1623 (see FIG. 13). The first groove 1621 is formed in a straight line extending from the upper end of each support plate 162 to approximately the center in the vertical direction. The second groove 1622 is formed in a straight line extending rearward from the lower end of the first groove 1621. The third groove 1623 is formed in a straight line extending diagonally upward and forward from the lower end of the first groove 1621. Further, a circular screw insertion hole 1624 penetrates below the first groove 1621, second groove 1622, and third groove 1623 in each support plate 162.
