The light source unit 100 and the emergency light source unit 500 may include a semiconductor light source such as a light-emitting diode.

[0011] The lighting fixture 1 of this embodiment has an elongated shape as a whole. Each of the light source unit 100, the cosmetic part 200, and the fixture body 300 has an elongated shape extending along the longitudinal direction of the lighting fixture 1. Typically, the lighting fixture 1 is installed in a position in which its longitudinal direction is horizontal. The control unit 400 is disposed in the central part of the lighting fixture 1 in the longitudinal direction. The emergency light source part 500 is disposed at two positions, one near one end of the lighting fixture 1 in the longitudinal direction and the other near the other end. The inspection part 600 has an inspection switch that is operated when inspecting whether the lighting fixture 1 maintains the functions required in an emergency. Typically, the cosmetic part 200 and the fixture body 300 are made of metal.

[0012] The first unit 700 is a unit including the cosmetic part 200 and the fixture body 300. The control unit 400 corresponds to the second unit. The first unit 700 has a storage space for storing at least a part of the light source unit 100 and at least a part of the control unit 400. The first unit 700 corresponds to the main body of the lighting fixture 1. The light source unit 100 is removable from the first unit 700. FIG. 2 is a perspective view showing a state in which the light source unit 100 has been removed from the first unit 700 of the lighting fixture 1 according to embodiment 1.

[0013] 2, the first unit 700 has a mounting recess 210, a recess communication opening 211, a spring 221, and a hook portion 222. The mounting recess 210 is a recess having an opening facing the front of the first unit 700. The mounting recess 210 has an elongated shape extending along the longitudinal direction of the first unit 700. The mounting recess 210 is formed by the decorative portion 200. When the light source unit 100 is mounted to the first unit 700, at least a portion of the light source unit 100 is stored in the space inside the mounting recess 210.

[0014] The recess communicating opening 211 is an opening formed in the bottom of the mounting recess 210. When the light source unit 100 is attached to the mounting recess 210, the recess communicating opening 211 is blocked by the light source unit 100.

[0015] The light source unit 100 can be fixed to the mounting recess 210 by the spring 221 and the hook portion 222. The spring 221 is installed at the bottom of the mounting recess 210. The spring 221 is located near one end of the mounting recess 210 in the longitudinal direction. The hook portion 222 is formed at the other end of the mounting recess 210 in the longitudinal direction. The light source unit 100 has an engagement portion (not shown) that engages with the spring 221 and the hook portion 222. The light source unit 100 may be configured to be able to be attached to and detached from the mounting recess 210 manually without using tools.

[0016] The decorative part 200 is a member that forms part of the exterior of the lighting fixture 1. In other words, the decorative part 200 forms the part of the lighting fixture 1 that is visible from the outside. The decorative part 200 is attached to the fixture body 300. The decorative part 200 has an inclined part 214 and an opening 212 formed in the inclined part 214. The opening 212 has a rectangular shape. In this embodiment, the provision of the decorative part 200 is advantageous in improving the appearance of the lighting fixture 1.

[0017] The control unit 400 includes a housing part 410 and a protruding part 420 protruding from the housing part 410. At least a part of the housing part 410 is located between the tool body 300 and the cosmetic part 200. The protruding part 420 protrudes from the housing part 410 to the outside of the cosmetic part 200 through the opening 212. The housing part 410 and the protruding part 420 are desirably made of a resin material. The protruding part 420 is formed integrally with the housing part 410.

[0018] Fig. 3 is an exploded perspective view of the lighting fixture 1 according to the first embodiment. The state shown in Fig. 3 corresponds to the state shown in Fig. 2 in which the cosmetic part 200 has been removed from the fixture body 300. As shown in Fig. 3, a cosmetic part mounting base 110 is installed on the fixture body 300. The cosmetic part 200 can be fixed to the fixture body 300 by fastening the cosmetic part 200 to the cosmetic part mounting base 110 with a screw.

[0019] The control unit 400 and the inspection section 600 are attached to the fixture body 300. The fixture body 300 is further provided with an emergency control unit 120, a power terminal block 131, a signal terminal block 132, and a storage battery 140. A commercial power supply of, for example, AC 100V is connected to the power terminal block 131. The power of the commercial power supply input to the power terminal block 131 is supplied to the light source unit 100 and the emergency control unit 120 via electric wires (not shown). The storage battery 140 stores energy for turning on the emergency light source section 500 in the event of a power outage of the commercial power supply. The emergency control unit 120 includes a charging circuit for charging the storage battery 140 with the power of the commercial power supply supplied from the power terminal block 131, a lighting circuit for turning on the emergency light source section 500 with the power supplied from the storage battery 140 in an emergency, a control circuit, and the like.

[0020] The emergency light source unit 500 is disposed on the inclined portion 214 of the decorative unit 200. An opening 213 is formed in the inclined portion 214 to expose the surface of the inspection unit 600. The signal line 150 connects between the emergency control unit 120 and the inspection unit 600. One end of the electric wire 160 is connected to the control unit 400. Although not shown in FIG. 3, the other end of the electric wire 160 is connected to the light source unit 100.

[0021] Fig. 4 is a block diagram showing a configuration of a portion of lighting fixture 1 according to embodiment 1. As shown in Fig. 4, light source unit 100 includes light source section 101 and lighting control device 102 that turns on light source section 101. Lighting control device 102 includes a lighting circuit that generates DC power for turning on light source section 101 from commercial power supplied from power supply terminal block 131, and a control circuit that controls the lighting state of light source section 101.

[0022] The control unit 400 is connected to the lighting control device 102 of the light source unit 100 via an electric wire 160. The control unit 400 controls the lighting state of the light source unit 101 via the lighting control device 102. The lighting control device 102 controls the lighting state of the light source unit 101 in response to a control signal from the control unit 400. The control unit 400 includes a control board 401 having a control circuit, a sensor module 402, a signal input unit 403, and a switch 431 that can be manually operated from outside the control unit 400. The signal input unit 403 is connected to a signal terminal block 132 installed in the fixture body 300 via an electric wire 170.

[0023] The sensor module 402 in this embodiment corresponds to a human sensor that detects whether or not a person is present within a detection range. The sensor module 402 in this embodiment corresponds to a radio wave sensor that transmits and receives radio waves such as microwaves. The sensor module 402 transmits radio waves within the detection range. The radio waves are reflected by an object within the detection range. The sensor module 402 receives the reflected waves. If the object that reflected the radio waves is moving, a change in frequency occurs between the transmitted radio waves and the received radio waves according to the moving speed of the object. The sensor module 402 can detect a person by utilizing the frequency difference between the transmitted wave and the reflected wave. In other words, the sensor module 402 can detect a person by using the Doppler effect.

[0024] The sensor module 402 corresponds to a signal receiving unit that receives a signal from the space outside the lighting fixture 1. The sensor module 402 receives radio waves reflected by an object within a detection range as a signal from the external space.

[0025] In the example shown in Fig. 4, an emergency light signal device 900 is connected to the lighting fixture 1. An electric wire 910 that transmits a signal from the emergency light signal device 900 is connected to the signal terminal block 132. A commercial power source of, for example, AC 100V is connected to the emergency light signal device 900. The emergency light signal device 900 is connected to an automatic fire alarm system 920. The emergency light signal device 900 in this embodiment corresponds to a signal sending unit provided outside the lighting fixture 1. A signal input unit 403 of the control unit 400 is connected to the emergency light signal device 900 via the electric wire 170, the signal terminal block 132, and the electric wire 910.

[0026] In the example shown in Fig. 4, the control unit 400 receives an automatic fire alarm interlocking signal from the emergency light signal device 900. The automatic fire alarm interlocking signal is a signal that is interlocked with the automatic fire alarm system 920. The normal automatic fire alarm interlocking signal is an AC 100V signal. For example, the automatic fire alarm interlocking signal in an emergency such as when a fire occurs is a 0V signal.

[0027] As shown in the example of FIG. 4, the signal input section 403 of the control unit 400 is connected to the emergency light signal device 900 via the electric wire 170, the signal terminal block 132, and the electric wire 910, and a mode in which the control unit 400 controls the lighting state of the light source section 101 in response to the signal of the signal input section 403 is referred to as a “first mode.”

[0028] The first mode is as follows. In a normal state where an automatic fire alarm interlocking signal of AC 100V is input to the signal input unit 403, the control unit 400 controls the lighting state of the light source unit 101 according to the signal of the sensor module 402. In this normal state, the control unit 400 may, for example, turn on the light source unit 101 at full brightness when the sensor module 402 detects a person, and may dim or turn off the light source unit 101 when the sensor module 402 does not detect a person. In this way, in the first mode, the state where the lighting state of the light source unit 101 is controlled according to the signal of the sensor module 402 is referred to as a "first state." In contrast, in an emergency where the automatic fire alarm interlocking signal input to the signal input unit 403 is 0V, the control unit 400 controls the lighting state of the light source unit 101 at a predetermined dimming rate regardless of whether the sensor module 402 detects a person or not. In this emergency, the control unit 400 may, for example, forcibly turn on the light source unit 101 with full light regardless of whether the sensor module 402 detects a person or not. In this way, in the first mode, a state in which the lighting state of the light source unit 101 is controlled by a predetermined dimming rate regardless of the signal from the sensor module 402 is referred to as a "second state." The first mode corresponds to a mode in which the signal input unit 403 is connected to the emergency light signal device 900, and the first state and the second state are switched by the control unit 400 in response to a signal from the emergency light signal device 900.

[0029] The lighting fixture 1 can also be used without being connected to a signal sending unit such as the emergency exit light signal device 900. In this case, since the automatic fire alarm interlocking signal is not input to the signal input unit 403, the signal of the signal input unit 403 is always 0 V. When the lighting fixture 1 is not connected to the emergency exit light signal device 900, the control unit 400 performs control in the "second mode". The second mode is a mode in which the signal input unit 403 is not connected to the emergency exit light signal device 900, and the control unit 400 controls the lighting state of the light source unit 101 in response to a signal from the sensor module 402. In the second mode, the control unit 400 may, for example, turn on the light source unit 101 at full brightness when the sensor module 402 detects a person, and turn off or dim the light source unit 101 when the sensor module 402 does not detect a person.

[0030] FIG. 5 is a block diagram showing a part of the configuration of the control unit 400 according to the first embodiment. As shown in FIG. 5, the control unit 400 includes a microcomputer 404, a regulator 405, a photocoupler 406, and a signal output terminal 407. The microcomputer 404 is provided on a control board 401. A light-emitting element, such as a light-emitting diode, of the photocoupler 406 is connected to a signal input unit 403. When the lighting fixture 1 is connected to the emergency light signal device 900, a fire alarm interlocking signal is input to the light-emitting element of the photocoupler 406. The switch 431 and a light-receiving element, such as a phototransistor, of the photocoupler 406 are connected to a circuit connecting the microcomputer 404 and the signal output terminal 407. The switch 431 is connected in parallel to the light-receiving element of the photocoupler 406. The signal output terminal 407 is connected to the light source unit 100 via an electric wire 160.

[0031] In this embodiment, the first mode and the second mode can be switched by the switch 431. As shown in FIG. 5, when the switch 431 is turned off, the first mode is selected. In the first mode, the following occurs. In a normal state in which an automatic fire alarm interlocking signal of AC 100V is input to the signal input unit 403, the light-emitting element of the photocoupler 406 emits light and the light-receiving element of the photocoupler 406 is turned on, so that the human presence / absence signal detected by the sensor module 402 is transmitted to the light source unit 100 via the signal output terminal 407. In this case, the first state is entered in which the lighting state of the light source unit 101 is controlled according to the human presence / absence signal detected by the sensor module 402. In contrast, in an emergency in which the automatic fire alarm interlocking signal of the signal input unit 403 is 0V, the light-emitting element of the photocoupler 406 does not emit light and the light-receiving element of the photocoupler 406 is turned off. As a result, the human presence / absence signal detected by the sensor module 402 is not transmitted to the light source unit 100. In this case, regardless of the signal from the sensor module 402, a second state is entered in which the lighting state of the light source unit 101 is controlled at a predetermined dimming rate.

[0032] On the other hand, when the switch 431 is turned on, the second mode is entered. In the second mode, the following occurs. Regardless of the signal of the signal input unit 403, the human presence signal detected by the sensor module 402 is transmitted to the light source unit 100 via the switch 431. As a result, regardless of the signal of the signal input unit 403, the lighting state of the light source unit 101 is controlled according to the signal of the sensor module 402.

[0033] In this embodiment, the first mode and the second mode can be switched simply by operating switch 431, and there is no need to perform an operation such as disconnecting wiring inside control unit 400. Therefore, when installing lighting fixture 1, it is possible to switch between the first mode and the second mode with a simple operation depending on whether or not it is connected to emergency light signal device 900. This makes the installation work of lighting fixture 1 easier.

[0034] In this embodiment, DC power generated by the DC power supply 103 included in the lighting control device 102 is supplied to the control unit 400 via the electric wire 160. This DC power is input to the microcomputer 404 via the regulator 405. In this way, the control unit 400 of this embodiment operates by receiving power supply from the lighting control device 102 of the light source unit 100. This has the following advantages: An AC / DC conversion circuit for supplying power to the control unit 400 is not required. The number of terminals and wiring of the control unit 400 can be reduced. Power conversion loss can be reduced.

[0035] FIG. 6 is a front view of the control unit 400 according to the first embodiment. FIG. 7 is a plan view of the control unit 400 according to the first embodiment. FIG. 8 is a left side view of the control unit 400 according to the first embodiment. FIG. 9 is a right side view of the control unit 400 according to the first embodiment. FIG. 10 is a perspective view of the control unit 400 according to the first embodiment as seen from the front side. FIG. 11 is a perspective view of the control unit 400 according to the first embodiment as seen from the rear side. FIG. 12 is an exploded perspective view of the control unit 400 according to the first embodiment. FIG. 13 is a perspective view showing a state in which the first housing 411 is removed from the second housing 412 of the control unit 400 according to the first embodiment.

[0036] 6 to 11, the housing 410 of the control unit 400 is formed by a first housing 411 and a second housing 412. As shown in FIG. 12, the first housing 411 is removable from the second housing 412. The first housing 411 mainly forms the front side of the housing 410. The second housing 412 mainly forms the rear side of the housing 410. The housing 410 has a hollow portion that houses the control board 401 and a part of the sensor module 402.

[0037] The control unit 400 in this embodiment further includes switches 432, 433, and 434. Each of the switches 431, 432, 433, and 434 is mounted on the control board 401. This allows the structure to be simplified. Each of the switches 431, 432, 433, and 434 is configured with a slide switch. Slide switches are inexpensive, which is advantageous for reducing costs. The switches 431, 432, 433, and 434 include operation units 431a, 432a, 433a, and 434a, respectively. When the operation units 431a, 432a, 433a, and 434a are slid, the switches 431, 432, 433, and 434 are switched.

[0038] The control board 401 is provided with a signal input unit 403 and an electric wire connection unit 408. The electric wire 160 is connected to the electric wire connection unit 408. The electric wire 170 is connected to the signal input unit 403.

[0039] The sensor module 402 is connected to the control board 401 via a signal line 409. A protrusion 420, a flange 440, an opening 441, and an opening 442 are formed on the first housing 411. The flange 440 forms a surface that protrudes from the base of the protrusion 420 toward the outer periphery like an eave. The opening 441 is an opening for exposing the signal input unit 403. The opening 442 is an opening for exposing the electric wire connection unit 408.

[0040] A base portion 443 and a rear through-hole 444 are formed in the second housing 412. A groove-shaped signal line holding portion 445 and a notch-shaped slide portion 446 are formed in the base portion 443. As shown in FIG. 13, the sensor module 402 is supported by the base portion 443. The signal line 409 is held by the signal line holding portion 445. The control board 401 is inserted inside the slide portion 446. When the control board 401 is attached to the first housing 411, the control board 401 can be easily assembled in an appropriate attachment position by sliding the control board 401 upward or sideways relative to the slide portion 446.

[0041] 10, operation sections 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 protrude to the outside of the housing section 410 through openings formed in the housing section 410. The switches 431, 432, 433, and 434 can be switched by operating the operation sections 431a, 432a, 433a, and 434a with fingers from outside the housing section 410.

[0042] The control unit 400 has a display section 450. The positions of the operation sections 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 and information corresponding to the positions are displayed on the display section 450. By providing the display section 450, it is possible to easily visually confirm what function has been switched to when the switches 431, 432, 433, and 434 are operated.

[0043] Display unit 450 displays "with" or "without" automatic fire alarm interlocking as information corresponding to the position of operation unit 431a of switch 431. When operation unit 431a is set to the "with" automatic fire alarm interlocking position, switch 431 is turned off and control unit 400 enters the first mode described above. When operation unit 431a is set to the "without" automatic fire alarm interlocking position, switch 431 is turned on and control unit 400 enters the second mode described above.

[0044] The switch 432 is a switch for switching the detection sensitivity of the sensor module 402. The display unit 450 displays detection sensitivity "80%" and "100%" as information corresponding to the position of the operation unit 432a of the switch 432. When the operation unit 432a is set to the detection sensitivity "80%", the control unit 400 goes into a mode in which 80% of the detection area of ​​the sensor module 402 is used to detect a person. In this mode, the detection area in which a person can be detected becomes relatively narrow, but this is advantageous in terms of reliably suppressing false detection. When the operation unit 432a is set to the detection sensitivity "100%", the control unit 400 goes into a mode in which 100% of the detection area of ​​the sensor module 402 is used to detect a person. In this mode, there is an advantage that the detection area in which a person can be detected becomes wider.

[0045] The switch 433 is a switch for switching the standby operation of the lighting device 1. The standby operation is the operation of the lighting device 1 when the sensor module 402 does not detect a person. The display unit 450 displays standby operation "10%", "30%" and "100%" as information corresponding to the position of the operation unit 433a of the switch 433. When the operation unit 433a is set to the standby operation "10%" position, the control unit 400 performs a process of turning on the light source unit 100 at a dimming rate of 10% when the sensor module 402 does not detect a person. When the operation unit 433a is set to the standby operation "30%" position, the control unit 400 performs a process of turning on the light source unit 100 at a dimming rate of 30% when the sensor module 402 does not detect a person. When the operation section 433a is set to the standby operation "100%" position, the control unit 400 performs processing to turn on the light source unit 100 at a dimming rate of 100% when the sensor module 402 does not detect a person.

[0046] The switch 434 is a switch for switching the lighting time after the sensor module 402 changes from a state in which a person is detected to a state in which a person is not detected. The display unit 450 displays lighting times of "10 seconds," "1 minute," and "3 minutes" as information corresponding to the position of the operation unit 434a of the switch 434. When the operation unit 434a is set to the position of the lighting time "10 seconds," the control unit 400 performs a process of transitioning to a standby state when 10 seconds have elapsed after the sensor module 402 changes from a state in which a person is detected to a state in which a person is not detected. When the operation unit 434a is set to the position of the lighting time "1 minute," the control unit 400 performs a process of transitioning to a standby state when 1 minute has elapsed after the sensor module 402 changes from a state in which a person is detected to a state in which a person is not detected. When the operation unit 434a is set to the position of the lighting time "3 minutes," the control unit 400 performs a process of transitioning to a standby state when 3 minutes have elapsed after the sensor module 402 changes from a state in which a person is detected to a state in which a person is not detected.

[0047] 2, the operation units 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 are disposed at positions where they can be operated by inserting a hand through the recess communication opening 211. The operation units 431a, 432a, 433a, and 434a and the display unit 450 are disposed between the recess communication opening 211 and the appliance body 300. An operator can visually recognize the operation units 431a, 432a, 433a, and 434a and the display unit 450 through the recess communication opening 211.

[0048] In a state where the light source unit 100 is removed from the first unit 700, the operation portions 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 can be touched, and therefore the switches 431, 432, 433, and 434 can be operated. In this embodiment, the switches 431, 432, 433, and 434 can be operated by removing the light source unit 100 from the first unit 700. Therefore, when it becomes necessary to change the setting state of the switches 431, 432, 433, and 434, the switches 431, 432, 433, and 434 can be switched by a simple operation.

[0049] 1, when the light source unit 100 is attached to the first unit 700, the light source unit 100 blocks the recess communication opening 211. In this state, the operation parts 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 cannot be touched, and therefore the switches 431, 432, 433, and 434 cannot be operated. In this embodiment, when the light source unit 100 is attached to the first unit 700, the switches 431, 432, 433, and 434 cannot be operated, and therefore the switches 431, 432, 433, and 434 can be reliably prevented from being switched erroneously.

[0050] In this embodiment, the direction corresponding to the left for an operator facing lighting fixture 1 is referred to as the “left”, the direction corresponding to the right for the operator is referred to as the “right”, and the direction connecting the left and right is referred to as the “left-right direction”. Switches 431, 432, 433, and 434 are switched by sliding operating units 431a, 432a, 433a, and 434a in the left-right direction, respectively.

[0051] The switches 432, 433, and 434 correspond to switches capable of switching a specific parameter of the lighting device 1. That is, by sliding the operation unit 432a, the parameter of "detection sensitivity" can be switched, by sliding the operation unit 433a, the parameter of "standby operation" can be switched, and by sliding the operation unit 434a, the parameter of "lighting time" can be switched. The switches 432, 433, and 434 are all configured such that, by sliding the operation units 432a, 433a, and 434a from left to right, the parameter to be switched increases. The horizontal axis of a graph is usually written so that the parameter increases from left to right. For this reason, it is easy for humans to intuitively understand that the parameter increases from left to right.

[0052] The display unit 450 is located at the back of the mounting recess 210. Therefore, when the switches 432, 433, and 434 are operated, it may be dark and difficult to see the display unit 450. In this embodiment, the parameter to be switched is increased when the operation units 432a, 433a, and 434a are slid from left to right. Therefore, the operator can easily intuitively understand which way to slide the operation units 432a, 433a, and 434a to increase or decrease the parameter. Therefore, even if it is dark and difficult to see the display unit 450, it is advantageous to appropriately switch the switches 432, 433, and 434.

[0053] As a modified example, the parameter to be switched may be configured to become smaller when the operation units 432a, 433a, and 434a are slid from left to right, inversely to the above. In this way, the parameter may be intentionally changed in the opposite direction to make the operator consciously operate the parameter.

[0054] Control unit 400 may also be provided with a slide switch that is switched by sliding an operation unit in a left-right direction, and a specific function of lighting device 1 may be switched on and off by sliding the operation unit. In this case, by configuring the function to change from off to on when the operation unit is slid from left to right, it is advantageous for appropriately switching the slide switch even when it is dark and display unit 450 is difficult to see. As a variation, the function may be configured to change from on to off when the operation unit is slid from left to right, which is the opposite of the above.

[0055] The colors of the operation units 431a, 432a, 433a, and 434a may be different from the colors of the parts of the display unit 450 that indicate the positions of the operation units 431a, 432a, 433a, and 434a. By doing so, the worker can more reliably visually recognize the positions of the operation units 431a, 432a, 433a, and 434a. The parts of the display unit 450 that indicate the positions of the operation units 431a, 432a, 433a, and 434a are parts that may overlap with the operation units 431a, 432a, 433a, and 434a when viewed from the worker facing the lighting fixture 1. For example, in FIG. 10, the position display units 451, 452, and 453 of the display unit 450 are parts that indicate the position of the operation unit 434a. In this case, the colors of the position display units 451, 452, and 453 are, for example, white, and the color of the operation unit 434a is, for example, black. When the white color of position display unit 451 is hidden by the black color of operation unit 434a, the operator can easily see that operation unit 434a is at the "10 seconds" position. Similarly, when the white color of position display unit 452 is hidden by the black color of operation unit 434a, the operator can easily see that operation unit 434a is at the "1 minute" position, and when the white color of position display unit 453 is hidden by the black color of operation unit 434a, the operator can easily see that operation unit 434a is at the "3 minutes" position.

[0056] The operation units 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 may be configured to have different shapes or dimensions. For example, the operation units 431a, 432a, 433a, and 434a may be configured to have different protruding lengths. By doing so, even if the operation units 431a, 432a, 433a, and 434a and the display unit 450 are dark and difficult to see, the operation units 431a, 432a, 433a, and 434a can be distinguished by touch, so that the switch to be operated can be easily found among the switches 431, 432, 433, and 434.

[0057] 11, a part of the control board 401 can be seen from a rear through-hole 444 that penetrates the rear surface of the housing 410. This can reliably prevent forgetting to attach the control board 401 when assembling the control unit 400. Furthermore, by providing the rear through-hole 444, the second housing 412 having the base portion 443, the sliding portion 446, etc. can be molded using a mold that is movable in the direction of the arrow A in FIG. 11. This makes it easier to manufacture the second housing 412.

[0058] An electric wire holding portion 447 and a cutout portion 448 are formed on the rear surface of the housing portion 410. The electric wire holding portion 447 is a long and narrow recess having a space capable of storing the electric wire 160. As shown in Figs. 8 and 9, the cutout portion 448 corresponds to a portion obtained by cutting out a lower corner of the rear surface of the housing portion 410. The signal wire 150 can be inserted into the space formed by the cutout portion 448.

[0059] FIG. 14 is a cross-sectional view of the lighting device 1 according to the first embodiment, cut along a plane perpendicular to the longitudinal direction of the lighting device 1. The cut position of the cross-sectional view of FIG. 14 corresponds to the center position of the control unit 400. As shown in FIG. 14, the first unit 700 has a first storage space 701, which is a space inside the mounting recess 210, and a second storage space 702, which is a space outside the mounting recess 210. A part of the light source unit 100 is stored in the first storage space 701. The light source unit 100 includes a translucent cover 104 that covers the light source section 101. Most of the translucent cover 104 is outside the mounting recess 210. The translucent cover 104 protrudes toward the front side with respect to the decorative section 200.

[0060] The control unit 400 has a portion other than the protruding portion 420 housed in the second storage space 702. In this embodiment, the control unit 400 is disposed in the second storage space 702 outside the mounting recess 210, thereby making it possible to widen the internal space of the mounting recess 210. This makes it possible to expand the storage space for the electric components and the like included in the light source unit 100. In addition, the working space when operating the switches 431, 432, 433, and 434 can be widened.

[0061] The fixture body 300 has a first surface 301. The first surface 301 corresponds to the back surface of the luminaire 1. The luminaire 1 is installed so that the first surface 301 faces a mounting surface such as a wall surface or ceiling surface of a building.

[0062] The mounting recess 210 is located on the opposite side to the first surface 301. In other words, the mounting recess 210 is located on the front side of the lighting fixture 1. The mounting recess 210 corresponds to a first light source mounting portion where the light source unit 100, which is the first light source, is mounted.

[0063] The plate-shaped inclined portion 214 is provided adjacent to the mounting recess 210. The inclined portion 214 is inclined so as to approach the first surface 301 as it moves away from the mounting recess 210 and the light source unit 100. The housing portion 410 of the control unit 400 is stored in the second storage space 702 inside the inclined portion 214. The protruding portion 420 protrudes into the external space of the lighting device 1 through the opening 212 formed in the inclined portion 214. In this embodiment, the housing portion 410 of the control unit 400 is disposed inside the decorative portion 200, and the periphery of the protruding portion 420 is covered by the decorative portion 200, which is advantageous in improving the appearance of the lighting device 1.

[0064] The protruding portion 420 has a cover 421 inclined with respect to the first surface 301. The cover 421 is inclined so as to approach the first surface 301 as it moves away from the mounting recess 210 and the light source unit 100. The cover 421 is inclined in the same direction as the inclined portion 214. At least a part of the sensor module 402 is located inside the protruding portion 420. The sensor module 402 has a surface portion 402a that faces the inner surface of the cover 421 through a space. The cover 421 covers the surface portion 402a. The radio wave transmitted from the surface portion 402a of the sensor module 402 passes through the cover 421 and is radiated to the external space. In addition, the reflected wave of the radio wave reflected by an object in the external space passes through the cover 421 and is received by the surface portion 402a of the sensor module 402. The entire surface portion 402a is located outside the surface of the inclined portion 214. This makes it possible to prevent radio waves transmitted and received by the sensor module 402 from being blocked by the metal inclined portion 214 .

[0065] In this embodiment, by forming an inclined portion 214 in the cosmetic part 200, it is possible to prevent the light emitted from the light source unit 100 from being blocked by the cosmetic part 200, making it possible to illuminate a wider range.

[0066] The surface portion 402a of the sensor module 402 is inclined so as to approach the first surface 301 as it moves away from the mounting recess 210 and the light source unit 100. By disposing the sensor module 402 at an angle in this manner, the range in which the sensor module 402 can detect people can be made wider. In addition, the cover 421 is positioned parallel to the surface portion 402a of the sensor module 402. This makes it possible to more reliably prevent radio waves transmitted from the surface portion 402a from being reflected by the cover 421, thereby improving the detection performance of the sensor module 402.

[0067] In this embodiment, the inclination angle (minor angle) of cover 421 with respect to first surface 301 is larger than the inclination angle (minor angle) of inclined portion 214 with respect to first surface 301. This prevents light emitted from light source unit 100 from being blocked by lower end portion 422 of cover 421, thereby suppressing light loss. Note that, even when the inclination angle (minor angle) of cover 421 with respect to first surface 301 is equal to the inclination angle (minor angle) of inclined portion 214 with respect to first surface 301, the same effect as above can be obtained.

[0068] The flange 440 of the control unit 400 is in contact with or close to the inner surface of the inclined portion 214 at the periphery of the opening 212. The surface of the flange 440 is inclined with respect to the first surface 301 so as to be parallel to the inclined portion 214.

[0069] In the following description, the direction perpendicular to the first surface 301 is referred to as the "first direction". The cylindrical figure 950 shown by the dashed line in FIG. 14 corresponds to a virtual cylindrical figure formed by a trajectory obtained by translating the edge of the opening 212 in the first direction. The cylindrical figure 950 is a rectangular cylinder. In this embodiment, the entire protrusion 420 is located inside the cylindrical figure 950. This has the following advantages. FIG. 15 is a cross-sectional view showing a state before the cosmetic part 200 is attached to the device body 300. The cutting position of the cross-sectional view in FIG. 15 is the same as that in FIG. 14. The control unit 400 is attached to the device body 300 before the cosmetic part 200 is attached. When attaching the cosmetic part 200, the cosmetic part 200 is brought closer to the device body 300 in a state where the cosmetic part 200 is facing the device body 300, and the cosmetic part 200 is combined with the device body 300. When combining the cosmetic part 200 with the tool body 300, it is necessary to insert the protruding part 420 into the opening 212. In this embodiment, the protruding part 420 can be inserted into the opening 212 by moving the cosmetic part 200 in a first direction relative to the tool body 300. Therefore, the cosmetic part 200 can be combined with the tool body 300 by moving the cosmetic part 200 in the first direction while facing the tool body 300. This makes it easy to attach the cosmetic part 200 to the tool body 300, and the operation can be performed easily and quickly.

[0070] Furthermore, in this embodiment, the size of the opening 212 can be made substantially the same as the size of the base of the protrusion 420. That is, the size of the opening 212 can be made substantially the same as the size of the protrusion 420 at the position of the surface of the flange 440. Therefore, the gap between the opening 212 and the protrusion 420 can be made small. In contrast, in a configuration in which the cosmetic part 200 must be moved in an oblique direction when attached to the tool body 300, the size of the opening 212 needs to be made sufficiently larger than the size of the base of the protrusion 420. In such a configuration, the gap between the opening 212 and the protrusion 420 cannot be made small.

[0071] The surface of the flange portion 440 corresponds to the boundary between the housing portion 410 and the protruding portion 420. As shown in FIG. 14, the protruding portion 420 in this embodiment has a wall portion 423 that connects between the cover 421 and the flange portion 440. The wall portion 423 protrudes from the flange portion 440 in the first direction. The wall portion 423 is located along the portion of the edge of the opening 212 that is closest to the first surface 301. In this embodiment, by providing such a wall portion 423, the entire protruding portion 420 can be located inside the cylindrical figure 950, while the internal space of the protruding portion 420 can be made sufficiently large. Therefore, the space in which the sensor module 402 is arranged can be made large.

[0072] Although the first embodiment has been described above, the present disclosure is not limited to the above-mentioned embodiment. For example, the signal sending unit may be an automatic fire alarm instead of the emergency light signal device 900, or may have a configuration in which an automatic fire alarm and an emergency light signal device are connected. In addition, the signal input from the signal sending unit is not limited to AC 100V, and may be, for example, a dimming signal sent from an emergency light signal device.

[0073] The signal receiving unit is not limited to a radio wave type human sensor such as the sensor module 402, but may be an infrared type human sensor that receives infrared rays emitted from a human body as a signal from an external space, a brightness sensor that receives the amount of light in the external space as a signal, or a light receiving unit for a remote control that receives electromagnetic waves emitted from the remote control as a signal from an external space. In addition, the switches 431, 432, 433, and 434 have been described as switches having a slide type mechanism, but instead of this, for example, a switch having a push button type mechanism or a switch having a mechanism for switching by inserting a needle or other tool may be used. In addition, the multiple switches 431, 432, 433, and 434 do not have to be unified into those having the same type of mechanism, and multiple types of mechanisms may be mixed.

[0074] Embodiment 2 Next, a second embodiment will be described with reference to FIGS. 16 to 18. The differences from the first embodiment will be mainly described, and descriptions of the same or corresponding parts will be simplified or omitted.

[0075] Fig. 16 to Fig. 18 are perspective views showing a part of lighting fixture 1 according to embodiment 2. As shown in Fig. 16 and Fig. 17, decorative part 200 in lighting fixture 1 of the present embodiment includes a lid part 230 that covers a storage battery storage part 180 for storing a storage battery 140. As shown in Fig. 17, lid part 230 is connected to a main body of decorative part 200 via a hinge part 231. Lid part 230 can be opened and closed by rotating lid part 230 about hinge part 231.

[0076] As shown in Fig. 16, when the lid part 230 is closed, the opening of the storage battery storage part 180 is blocked by the lid part 230, and the storage battery 140 is not visible from the outside. As shown in Fig. 17, when the lid part 230 is opened, the opening of the storage battery storage part 180 is exposed, and the storage battery 140 is visible from the outside.

[0077] When the lid portion 230 is opened, the storage battery 140 can be removed from the lighting fixture 1. Fig. 18 shows the storage battery 140 removed from the lighting fixture 1. In this embodiment, since the storage battery 140 can be removed by opening the lid portion 230, there is no need to remove the decorative portion 200 when inspecting or replacing the storage battery 140. This makes it possible to inspect or replace the storage battery 140 easily and in a short time. [Explanation of symbols]
