Be prepared.

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 section 101 via the lighting control device 102.

The sensor module 402 in this embodiment corresponds to a human sensor that detects whether a person is present within the detection range. The sensor module 402 in this embodiment corresponds to a radio wave sensor that transmits and receives radio waves such as microwaves, for example. The sensor module 402 transmits radio waves within the detection range. Radio waves are reflected by objects within the detection range. Sensor module 402 receives the reflected wave. If the object that reflected the radio waves is moving, a change in frequency will occur between the emitted and received radio waves depending on the object's moving speed. According to the sensor module 402, a person can be detected using the frequency difference between the transmitted wave and the reflected wave. That is, according to the sensor module 402, a person can be detected using the Doppler effect.

The sensor module 402 corresponds to a signal receiving section that receives signals from a space outside the lighting fixture 1. The sensor module 402 receives radio waves reflected by objects within the detection range as signals from external space.

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

In the example shown in FIG. 4, the control unit 400 receives the self-fire alarm interlocking signal from the guide light signaling device 900. The automatic fire alarm interlocking signal is a signal interlocking with the automatic fire alarm equipment 920. The constant self-fire alarm interlocking signal is an AC 100V signal. For example, the self-fire alarm interlocking signal in an emergency such as when a fire occurs is a 0V signal.

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

In the first mode, it is as follows. When the AC 100V self-fire alarm interlocking signal is input to the signal input section 403, the control unit 400 controls the lighting state of the light source section 101 according to the signal from the sensor module 402. At this constant time, the control unit 400, for example, turns on the light source section 101 at full brightness when the sensor module 402 detects a person, and dims or turns off the light source section 101 when the sensor module 402 does not detect a person. Good too. Thus, in the first mode, the state in which the lighting state of the light source section 101 is controlled according to the signal from the sensor module 402 is referred to as a "first state." On the other hand, in an emergency situation when the self-fire alarm interlocking signal input to the signal input section 403 is 0V, the control unit 400 performs a predetermined signal regardless of whether the sensor module 402 detects a person. The lighting state of the light source section 101 is controlled based on the dimming rate. In this emergency, the control unit 400 may, for example, force the light source section 101 to turn on all lights, regardless of whether the sensor module 402 detects a person. Thus, in the first mode, a state in which the lighting state of the light source unit 101 is controlled according to a predetermined dimming rate regardless of the signal from the sensor module 402 is referred to as a "second state." In the first mode, the signal input section 403 is connected to the guide light signal device 900, and the first state and the second state are switched by the control unit 400 according to the signal from the guide light signal device 900. Corresponds to the mode in which

The lighting equipment 1 can also be used without connecting the lighting equipment 1 to a signal sending unit such as the guide light signaling device 900. In this case, since the self-fire alarm interlocking signal is not input to the signal input section 403, the signal of the signal input section 403 is always 0V. When the lighting fixture 1 is not connected to the guide light signaling device 900, the control unit 400 performs the "second mode" control. The second mode is a mode in which the signal input section 403 is not connected to the guide light signal device 900, and the control unit 400 controls the lighting state of the light source section 101 according to the signal from the sensor module 402. . In the second mode, for example, the control unit 400 turns on the light source section 101 at full brightness when the sensor module 402 detects a person, and dims or turns off the light source section 101 when the sensor module 402 does not detect a person. You may let them.

FIG. 5 is a block diagram showing a partial configuration of 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. A microcomputer 404 is provided on the control board 401. A light emitting element such as a light emitting diode of the photocoupler 406 is connected to the signal input section 403 . When the lighting fixture 1 is connected to the guide light signal device 900, the self-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 with the light receiving element of the photocoupler 406. Signal output terminal 407 is connected to light source unit 100 via electric wire 160.

In this embodiment, the first mode and the second mode can be switched by switch 431. As shown in FIG. 5, when switch 431 is turned off, the first mode is entered. In the first mode, it is as follows. When an AC 100V self-fire alarm interlocking signal 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 turns on, thereby generating a 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 such that the lighting state of the light source section 101 is controlled according to the presence/absence signal detected by the sensor module 402. On the other hand, in an emergency when the self-fire alarm interlocking signal of the signal input section 403 becomes 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 presence/absence signal detected by the sensor module 402 is no longer transmitted to the light source unit 100. In this case, a second state is entered in which the lighting state of the light source section 101 is controlled according to a predetermined dimming rate regardless of the signal from the sensor module 402.

On the other hand, when the switch 431 is turned on, the second mode is entered. In the second mode: Regardless of the signal from the signal input section 403, the presence/absence signal detected by the sensor module 402 is transmitted to the light source unit 100 via the switch 431. Thereby, the lighting state of the light source section 101 is controlled according to the signal from the sensor module 402 regardless of the signal from the signal input section 403.

According to this embodiment, it is possible to switch between the first mode and the second mode simply by operating the switch 431, and there is no need to perform work such as removing the wiring inside the control unit 400, for example. Therefore, when installing the 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 the guide light signal device 900. Therefore, the construction work of the lighting fixture 1 becomes easier.

In this embodiment, DC power generated by DC power supply 103 included in lighting control device 102 is supplied to control unit 400 via 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 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 becomes unnecessary. The number of terminals and wiring of the control unit 400 can be reduced. Power conversion loss can be reduced.

When the light source unit 100 is removed from the first unit 700, the operation parts 431a, 432a, 433a, 434a of the switches 431, 432, 433, 434 can be touched, so the switches 431, 432, 433, 434 cannot be operated. It is operable. In this embodiment, it becomes possible to operate the switches 431, 432, 433, and 434 by removing the light source unit 100 from the first unit 700. Therefore, when it becomes necessary to change the settings made by the switches 431, 432, 433, and 434, the switches 431, 432, 433, and 434 can be changed with a simple operation.

As shown in FIG. 1, when the light source unit 100 is attached to the first unit 700, the light source unit 100 closes the recess communication opening 211. In this state, the operating parts 431a, 432a, 433a, 434a of the switches 431, 432, 433, 434 cannot be touched, so the switches 431, 432, 433, 434 cannot be operated. In this embodiment, the switches 431, 432, 433, and 434 cannot be operated while the light source unit 100 is attached to the first unit 700, so the switches 431, 432, 433, and 434 may be switched by mistake. You can definitely prevent this from happening.

In this embodiment, the direction that corresponds to the left for a worker directly facing the lighting equipment 1 is defined as "left", the direction that corresponds to the right for the worker is defined as "right", and the direction connecting the left and right is defined as "left". It is called "left-right direction." The switches 431, 432, 433, and 434 are switched by sliding the operation parts 431a, 432a, 433a, and 434a in the left and right direction, respectively.

The switches 432, 433, and 434 correspond to switches that can change specific parameters of the lighting fixture 1. That is, by sliding the operating part 432a, the parameter of "detection sensitivity" can be changed, by sliding the operating part 433a, the parameter of "standby operation" can be changed, and by sliding the operating part 434a, the parameter of "lighting time" can be changed. ” parameters can be switched. The switches 432, 433, and 434 are all configured so that when the operating portions 432a, 433a, and 434a are slid from left to right, the parameter to be switched becomes larger. The horizontal axis of the graph is usually written so that the parameters increase from left to right. Therefore, it is easy for humans to intuitively understand that parameters increase from left to right.

The display section 450 is located at the back of the mounting recess 210. Therefore, when operating the switches 432, 433, and 434, it may be difficult to see the display section 450 because it is dark. In this embodiment, when the operating units 432a, 433a, and 434a are slid from left to right, the parameter to be switched becomes larger. Therefore, it is easy for the operator to intuitively understand in which direction the operating sections 432a, 433a, and 434a should be slid to increase or decrease the parameter. Therefore, even if it is dark and difficult to see the display section 450, it is advantageous to appropriately switch the switches 432, 433, and 434.

As a modification, it may be configured such that, contrary to the above, when the operation units 432a, 433a, 434a are slid from left to right, the parameter to be changed becomes smaller. In this way, by intentionally changing the parameters in the opposite direction, the operator may intentionally operate the parameters.

Further, the control unit 400 may include a slide switch that can be switched by sliding the operating section in the left-right direction, and may be configured to be able to switch on/off a specific function of the lighting fixture 1 by sliding the operating section. In that case, by making the function switch from OFF to ON by sliding the operation unit from left to right, the slide switch can be appropriately operated even if it is dark and it is difficult to see the display unit 450. This will be advantageous when switching. As a modification, contrary to the above, the function may be turned from on to off by sliding the operation section from left to right.

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

The operating parts 431a, 432a, 433a, 434a of the plurality of switches 431, 432, 433, 434 may have different shapes or dimensions. For example, the operating parts 431a, 432a, 433a, and 434a may be configured to have different protrusion lengths. By doing so, even if the operating sections 431a, 432a, 433a, 434a and the display section 450 are dark and difficult to see, you can distinguish between the operating sections 431a, 432a, 433a, 434a by groping, and the switch Among 431, 432, 433, and 434, the switch to be operated can be easily found.

As shown in FIG. 11, a part of the control board 401 can be visually recognized through the back surface through hole 444 that penetrates the back surface of the housing section 410. Therefore, it is possible to reliably prevent forgetting to attach the control board 401 when assembling the control unit 400. Further, by providing the back surface through hole 444, the second housing 412 having the pedestal portion 443, the slide portion 446, etc. can be molded using a mold that moves in the direction of arrow A in FIG. Therefore, manufacturing of the second housing 412 becomes easy.

A wire holding portion 447 and a notch portion 448 are formed on the back surface of the housing portion 410. The wire holding portion 447 is an elongated recessed portion having a space in which the wire 160 can be accommodated. As shown in FIGS. 8 and 9, the cutout portion 448 corresponds to a portion obtained by cutting out a lower corner of the back surface of the housing portion 410. The signal line 150 can be inserted into the space formed by the notch 448.

FIG. 14 is a cross-sectional view of the lighting fixture 1 according to the first embodiment, taken along a plane perpendicular to the longitudinal direction of the lighting fixture 1. The cutting position of the cross-sectional view in 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 light-transmitting cover 104 that covers the light source section 101. Most of the transparent cover 104 is outside the mounting recess 210. The light-transmitting cover 104 protrudes toward the front side with respect to the decorative portion 200.

A portion of the control unit 400 other than the protrusion 420 is housed in a second storage space 702. In this embodiment, by arranging the control unit 400 in the second storage space 702 outside the mounting recess 210, the internal space of the mounting recess 210 can be made larger. Therefore, the storage space for electrical components included in the light source unit 100 can be expanded. Furthermore, the work space for operating the switches 431, 432, 433, and 434 can be expanded.

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

Attachment recess 210 is on the opposite side of first surface 301. That is, the mounting recess 210 is located at the front of the lighting fixture 1. The attachment recess 210 corresponds to a first light source attachment portion to which the light source unit 100, which is the first light source, is attached.

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 section 410 of the control unit 400 is housed in the second storage space 702 inside the inclined section 214. The protruding portion 420 passes through the opening 212 formed in the inclined portion 214 and protrudes into the external space of the lighting fixture 1. In this embodiment, the housing section 410 of the control unit 400 is arranged inside the decorative section 200, and the periphery of the protruding section 420 is covered by the decorative section 200, thereby improving the appearance of the lighting fixture 1. It will be advantageous to do so.

The protrusion 420 has a cover 421 that is inclined with respect to the first surface 301. The cover 421 is inclined so that it approaches 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 portion of sensor module 402 is located inside protrusion 420 . The sensor module 402 has a surface portion 402a that faces the inner surface of the cover 421 with a space therebetween. Cover 421 covers surface portion 402a. Radio waves emitted from the surface portion 402a of the sensor module 402 are transmitted through the cover 421 and radiated to the external space. In addition, reflected waves of radio waves reflected by objects in the external space are transmitted through the cover 421 and 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. Thereby, the radio waves transmitted and received by the sensor module 402 can be prevented from being blocked by the metal inclined portion 214.

According to this embodiment, by forming the inclined part 214 in the decorative part 200, it is possible to prevent the light emitted from the light source unit 100 from being blocked by the decorative part 200, so that a wider area can be illuminated. It becomes possible.

The surface portion 402a of the sensor module 402 is inclined so that it approaches the first surface 301 as it moves away from the mounting recess 210 and the light source unit 100. By arranging the sensor module 402 diagonally in this way, the detection range of a person by the sensor module 402 can be made wider. Further, the cover 421 is located parallel to the surface portion 402a of the sensor module 402. Thereby, it is possible to more reliably suppress the radio waves emitted from the surface portion 402a from being reflected by the cover 421, so that the detection performance of the sensor module 402 can be improved.

In this embodiment, the angle of inclination (inferior angle) of cover 421 with respect to first surface 301 is larger than the angle of inclination (inferior angle) of inclined portion 214 with respect to first surface 301 . Thereby, the light emitted from the light source unit 100 is not blocked by the lower end portion 422 of the cover 421, so that light loss can be suppressed. Note that even when the inclination angle (inferior angle) of the cover 421 with respect to the first surface 301 is equal to the inclination angle (inferior angle) of the inclined portion 214 with respect to the first surface 301, the same effect as described above can be obtained.

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

In the following description, a direction perpendicular to the first surface 301 will be referred to as a "first direction." A cylindrical figure 950 indicated by a broken line in FIG. 14 corresponds to a virtual cylindrical figure formed by a locus obtained by translating the edge of the opening 212 in the first direction. The cylindrical figure 950 has a rectangular cylindrical shape. 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 decorative part 200 is attached to the instrument main body 300. The cutting position of the cross-sectional view of FIG. 15 is the same as that of FIG. 14. The control unit 400 is attached to the instrument body 300 before the cosmetic part 200 is attached. When attaching the cosmetic section 200, the cosmetic section 200 is brought closer to the instrument main body 300 with the cosmetic section 200 directly facing the instrument main body 300, and the cosmetic section 200 is combined with the instrument main body 300. When combining the decorative part 200 with the instrument main body 300, it is necessary to insert the protruding part 420 into the opening 212. According to this embodiment, the protrusion 420 can be inserted into the opening 212 by moving the decorative part 200 in the first direction relative to the instrument main body 300. Therefore, the cosmetic section 200 can be combined with the instrument main body 300 by moving the cosmetic section 200 in the first direction with the cosmetic section 200 directly facing the instrument main body 300. Therefore, the work of attaching the decorative part 200 to the instrument main body 300 is easy, and the work can be carried out easily and quickly.

Furthermore, in this embodiment, the size of the opening 212 can be made approximately the same size as the root portion of the protrusion 420. That is, the size of the opening 212 can be made approximately 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 reduced. On the other hand, if the decorative part 200 is configured to have to be moved diagonally when attached to the instrument main body 300, the size of the opening 212 is set to be smaller than the size of the base of the protruding part 420. It needs to be large enough. With such a configuration, the gap between the opening 212 and the protrusion 420 cannot be reduced.

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

Although Embodiment 1 has been described above, the present disclosure is not limited to the above-described embodiment. For example, instead of the guide light signal device 900, the signal sending unit may be an automatic fire alarm, or may have a configuration in which an automatic fire alarm and a guide light signal device are connected. Further, the signal input from the signal sending unit is not limited to AC100V, and may be a dimming signal sent from a guide light signaling device, for example.

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 the human body as a signal from an external space, or It may be a brightness sensor that receives the amount of light in a space as a signal, or it may be a light receiving section for a remote control that receives electromagnetic waves emitted from a remote controller as a signal from an external space. Further, the switches 431, 432, 433, and 434 have been described using switches with a sliding mechanism as an example, but instead of this, switches with a push button mechanism may be used, or switches with a push button mechanism may be used instead. Alternatively, a switch having a mechanism for switching by inserting another tool may be used. Moreover, the plurality of switches 431, 432, 433, and 434 do not have to be unified to have the same type of mechanism, and may have a plurality of types of mechanisms mixed together.
