  The second connector 615 is mounted on one end (front end) in the longitudinal direction on the lower surface of the second printed wiring board 610. The first switch 611 is mounted behind the second connector 615 on the lower surface of the second printed wiring board 610. The second switch 612 is mounted on the other end (rear end) in the longitudinal direction on the lower surface of the second printed wiring board 610.

  The display unit 613 includes, for example, an LED chip that emits green light. The display unit 613 is mounted in front of the second switch 612 on the lower surface of the second printed wiring board 610. For example, the receiving unit 614 is configured to receive a control signal using infrared as a communication medium from the outside and demodulate a transmission frame from the received control signal. This control signal is transmitted from a remote controller operated by an inspection operator who performs a periodic inspection operation. The receiving unit 614 is mounted between the display unit 613 and the first switch 611 on the lower surface of the second printed wiring board 610. In short, the first and second switches 611, 612, the display unit 613, and the receiving unit 614 are arranged along the second direction (front-rear direction) with the first switch 611, the receiving unit 614, the display unit 613, the second unit. The switches 612 are arranged in this order (see FIG. 1).

  The second connector 615 is electrically connected to the first connector 604 of the first circuit block 60 by, for example, a cable. The control circuit of the first circuit block 60 is configured to monitor the operation states (ON and OFF) of the first and second switches 611 and 612 through the cable. The control circuit is configured to receive a transmission frame of a control signal demodulated by the receiving unit 614 through a cable. Further, the control circuit is configured to cause the display unit 613 to emit light by causing a current to flow through the cable to the display unit 613 when the charging circuit of the first circuit block 60 is operating.

  The control circuit is configured to perform a self-inspection operation (first inspection operation) when the first switch 611 is turned on or when a transmission frame is received from the reception unit 614. The self-inspection operation is to stop the charging circuit, operate the lighting circuit for a predetermined time (for example, 30 minutes or 60 minutes), stop the lighting circuit again, and operate the charging circuit. is there. When performing a regular inspection work, the inspection worker causes the self-inspection operation (first inspection operation) to be performed through the first switch 611 or the remote controller.

  Furthermore, the control circuit is configured to perform another inspection operation (second inspection operation) different from the self-inspection operation when the second switch 612 is turned on. The second inspection operation is to stop the charging circuit and operate the lighting circuit while the second switch 612 is on. When the second switch 612 is turned off, the lighting circuit is stopped and the charging circuit is operated. However, it is preferable that the control circuit is configured to perform the second inspection operation even when the transmission frame instructing to perform the second inspection operation is received from the reception unit 614. When the user performs the inspection work, the user performs this inspection operation (second inspection operation) through the second switch 612.

  Here, it is desirable that the display unit 613 displays at least a state related to the second inspection operation. For example, the display unit 613 may be configured to emit green light while the charging circuit is operating, and to turn off during the second inspection operation, that is, the charging circuit is stopped and the lighting circuit is operating. Good. However, it is desirable that the display unit 613 is configured not to be turned off during the operation of the lighting circuit, not only for the second inspection operation but also for the first inspection operation.

  The housing 62 includes a first housing 620 and a second housing 621. The first housing 620 has a bottom 6200 and a side wall 6201. The bottom 6200 is formed in a substantially rectangular box shape. The bottom 6200 is configured to support the solder surface of the first printed wiring board 600 of the first circuit block 60 from the thickness direction (vertical direction). The side wall part 6201 is formed in a plate shape. The side wall part 6201 is connected to the bottom part 6200 via a hinge. Therefore, the side wall portion 6201 is configured to be rotatable with respect to the bottom portion 6200 around the hinge. Further, the side wall portion 6201 is configured to support an end portion (left end portion) along the longitudinal direction of the second printed wiring board 610 of the second circuit block 61 sandwiched from the thickness direction.

  The second housing 621 is formed in a box shape with an upper surface and a left side surface opened. Second housing 621 is coupled to first housing 620. The upper surface of the second housing 621 is closed by the bottom 6200 of the first housing 620. Further, the left side surface of the second housing 621 is closed by the side wall portion 6201 of the first housing 620 (see FIG. 8).

  The second housing 621 has a projecting portion 6210 that protrudes downward from the left end of the lower surface (see FIGS. 1 and 10). The protruding part 6210 is formed in a truncated pyramid shape. The protruding portion 6210 has two operation members (a first operation member 6214 and a second operation member 6215). The first operation member 6214 is provided at the front end of the lower surface of the projecting part 6210. Further, the second operation member 6215 is provided at the rear end of the lower surface of the projecting part 6210.

  In the present embodiment, the first operating member 6214 and the second operating member 6215 have the same dimensions and the same shape. Therefore, since the projecting part 6210 can be manufactured using two identical members, the manufacturing cost can be reduced. As shown in FIG. 1, each of the first operating member 6214 and the second operating member 6215 includes a cylindrical base portion 621A having an open upper surface and a rod-shaped contact portion 621B protruding upward from the base portion 621A. ing.

On the other hand, the projecting part 6210 has two accommodation chambers for individually accommodating the first operation member 6214 and the second operation member 6215. The claw portion 621C of each base portion 621A is hooked so as to be movable in the vertical direction with respect to a recess formed on the inner peripheral surface of the corresponding storage chamber. Therefore, the first operating member 6214 and the second operating member 6215 are configured to be movable in the vertical direction with respect to the lower surface of the projecting part 6210 without dropping from the projecting part 6210. Then, the first switch 611 is turned on when the contact portion 621B of the first operation member 6214 pushed upward pushes the push button of the first switch 611. Further, when the contact portion 621B of the second operating member 6215 pushed upward pushes the push button of the second switch 612, the second switch 612 is turned on. In other words, the first operating member 6214 and the second operating member 6215 are both arranged to push the first switch 611 and the second switch 612 along the same direction (vertical direction).

  Further, circular windows 6216 and 6217 are provided between the first operation member 6214 and the second operation member 6215 on the lower surface of the protruding portion 6210. The front window 6216 faces the receiving unit 614 of the second circuit block 61 in the vertical direction. The rear window 6217 faces the display unit 613 of the second circuit block 61 in the vertical direction. That is, the control signal transmitted from the remote controller reaches the receiving unit 614 through the front window 6216. In addition, light (green light) emitted from the display portion 613 is radiated out of the housing 62 through the rear window 6217.

  As shown in FIG. 1, the projecting part 6210 includes a cylindrical light guide part 65 that forms the periphery of the window 6216 and that has both ends in the vertical direction opened. The light guide unit 65 extends in the vertical direction so that the upper end of the light guide unit 65 faces the receiving unit 614. The inner peripheral surface of the light guide unit 65 has a reflection surface, and efficiently collects infrared rays transmitted from the remote controller onto the reception unit 614.

  The second housing 621 has three openings 6211, 6212, 6213 at the right end. These three openings 6211, 6212, 6213 are arranged in a line along the front-rear direction (see FIG. 10). The opening 6211 at the front end faces the receiving connector 64 of the first circuit block 60. The input terminal block 603 is inserted through the opening 6213 at the rear end. The central opening 6212 faces the output connector 602 (see FIG. 9).

  The heat radiating plate 63 has a mounting portion 630 to which the emergency light source unit 4 is attached, a pair of leg portions 631, and a pair of fixing portions 632 (see FIG. 10). The attachment portion 630 is formed in a substantially trapezoidal shape. The pair of leg portions 631 is formed in a flat plate shape and protrudes upward from the front end and the rear end of the attachment portion 630. The pair of fixing portions 632 protrude from the upper ends of the pair of leg portions 631 in a direction approaching each other along the front-rear direction. However, in this embodiment, the attachment portion 630, the pair of leg portions 631, and the pair of fixing portions 632 are integrally formed of a plate material made of aluminum or an aluminum alloy.

It is attached to the housing 62 so as to be hooked on the upper surface of the bottom portion 6200 of the bottom (see FIG. 9). In addition, the heat radiating plate 63 is formed by fitting projections 6218 protruding from the upper ends of the upper surface and the lower surface of the second housing 621 into the rectangular fitting holes 633 provided in the pair of leg portions 631. It is positioned with respect to the housing 62 (see FIGS. 9 and 10).

  The emergency light source unit 4 is attached to the attachment portion 630 by screwing the holder 41 into the screw hole 6300 provided in the attachment portion 630 of the heat sink 63 (see FIGS. 7 to 10). . The emergency light source unit 4 is connected to the output connector 602 exposed from the central opening 6212 of the second housing 621 by inserting the terminal plate holding portion 410 of the holder 41 into the first connector of the control device 6. The circuit block 60 is electrically connected (see FIG. 8). Furthermore, the LED module 40 is thermally coupled to the mounting portion 630 (heat radiating plate 63) via the heat radiating sheet 43 (see FIG. 8).

  The control apparatus 6 is accommodated in the left end in the instrument main body 10 (refer FIG. 12). The control device 6 is preferably fixed to the instrument body 10 by screwing the pair of fixing portions 632 of the heat radiating plate 63 to the top plate 11. That is, the heat generated by the LED module 40 is conducted from the heat radiating sheet 43 to the heat radiating plate 63, and further conducted from the heat radiating plate 63 to the instrument body 10 to be radiated.

  The main piece 80 is formed in an L shape when viewed from below. The main piece 80 has a female screw portion 800. The hook piece 81 has a curved portion 810 that is curved in an arc shape, a connecting portion 811 that connects the curved portion 810 and the main piece 80, and a rectangular flat portion 812 that protrudes from the lower end of the curved portion 810 ( 5A-5C and FIG. 7). The hook piece 81 is connected to the lower portion at the left end of the main piece 80 by a connecting portion 811. Note that the hook piece 81 is configured such that the bending portion 810 can be displaced in the left-right direction when the connecting portion 811 is bent in the thickness direction. The side piece 82 is formed in a rectangular shape. The side piece 82 protrudes downward and leftward from the rear end of the main piece 80. The lower part of the side piece 82 is inclined rearward. The 1st insertion piece 83 and the 2nd insertion piece 84 are formed in L shape seeing from the front-back direction (refer FIG. 5B and FIG. 6B). The second insertion piece 84 is preferably formed by cutting and raising the main piece 80. The 3rd insertion piece 85 is formed in L shape seeing from the front-back direction (refer FIG. 5B and FIG. 6B).

Here, when the connecting part 811 is bent by the force applied to the flat part 812, the bending part 810 is displaced rightward and the hooking part 810 and the protruding part 524 are released. When the emergency power supply unit 5 is pulled downward in a state where the hooking of the curved portion 810 and the protrusion 524 is released, the first contact 57 and the second contact 58 become the first contact receiver 641 and the second contact. It is pulled out from the receptacle 642. In other words, the operator can complete the electrical connection work between the emergency power supply unit 5 and the control device 6 almost simultaneously with the work of housing the emergency power supply unit 5 in the instrument body 10. In addition, the operator can complete the electrical disconnection work between the emergency power supply unit 5 and the control device 6 almost simultaneously with the removal work of the emergency power supply unit 5 from the instrument body 10.

(2.4.6) Cover The cover 7 includes a first cover 71 and a second cover 72 as shown in FIG. The first cover 71 and the second cover 72 are connected so as to be aligned in the left-right direction by a long connecting body 73 formed in an L shape when viewed from the front-rear direction. In addition, it is preferable that the 1st cover 71, the 2nd cover 72, and the connection body 73 are integrally formed with a nonflammable material like a metal. For example, the cover 7 is preferably made of aluminum die casting. However, the cover 7 may be made of a nonflammable material other than metal, such as ceramics.

  The first cover 71 is formed in a box shape whose upper surface is open. The lower surface of the first cover 71 is formed in a curved shape that protrudes gently downward from both ends toward the center in the short side direction (front-rear direction), similarly to the translucent cover 20 of the service lighting device 2 (see FIG. 4 and FIG. 7). A recess 710 is formed on the lower surface of the first cover 71. The concave portion 710 has an elliptical shape when viewed from below (see FIG. 5A). A hole 711 passes through the center (bottom) of the recess 710. The hole 711 is formed in a shape (elliptical shape) through which the lens body 440 of the lens 44 can be inserted. The recess 710 is formed so that both ends in the major axis direction (left-right direction) protrude downward from both ends in the minor axis direction (front-rear direction) (see FIG. 5B).

  The first cover 71 has four through-holes (a first through-hole 712, a second through-hole 715, a third through-hole 713, and a fourth through-hole 714) at the left end on the lower surface thereof (FIGS. 5A and 5B). 7). These through holes are arranged in a line from the front to the rear in the order of the first through hole 712, the third through hole 713, the fourth through hole 714, and the second through hole 715.

  The first cover 71 has two hook portions 716 at the left end on the upper surface thereof (see FIG. 6A). The hook portion 716 is formed in an L shape when viewed from the front-rear direction (see FIG. 6B). Further, the hooking portion 716 is configured to incline upward as it approaches the tip (left end) (see FIG. 6B).

  As shown in FIG. 7, the second cover 72 has a flat part 720, an arm part 721, and a fixing part 722. The flat part 720 is formed in a substantially rectangular flat plate shape. The flat portion 720 is connected to the connecting body 73 at the left end. The arm part 721 is formed in a substantially rectangular flat plate shape. The arm portion 721 is configured to rise upward from the front end at the right end of the flat portion 720. The fixing portion 722 is formed in a substantially rectangular flat plate shape. The fixing portion 722 is configured to protrude rightward from the upper end of the arm portion 721. The fixing portion 722 has a circular screw insertion hole 723 at the right corner near the front.

  As shown in FIGS. 5A to 5C, the cover 7 covers a part (left end) of the emergency light source unit 4, the control device 6, and the emergency power supply unit 5 from below with the first cover 71, and the second cover 72. Is configured to cover the entire rest of the emergency power supply unit 5 from below. The lens body 440 of the emergency light source unit 4 is inserted through the hole 711 of the first cover 71 and exposed outside the cover 7.

  The first operating member 6214 faces the first through hole 712 of the first cover 71 (see FIGS. 1 and 5A). In the present embodiment, the first through hole 712 has a diameter that prohibits the insertion of the test finger. Here, the test finger is, for example, a pseudo finger defined in Annex 4 (2) c of the Japanese Electrical Appliance and Material Safety Law. Since the diameter dimension of the first through hole 712 is defined in this way, the first operation member 6214 does not accept a pressing operation with a human finger. The first operation member 6214 is pushed by a jig inserted through the first through hole 712.

  The second operating member 6215 faces the second through hole 715 of the first cover 71 (see FIG. 1). In the present embodiment, the second through-hole 715 has a diameter that allows the test finger to be inserted. Since the diameter dimension of the second through hole 715 is defined in this way, the second operation member 6215 is pushed by a human finger, for example. Further, the second operation member 6215 is partially inserted into the second through hole 715 of the first cover 71 in a state in which the second operation member 6215 is not pushed upward. As shown in FIG. 1, the second operating member 6215 has at least a portion thereof (second lower portion of the base portion 621 </ b> A in the illustrated example) when viewed in the left-right direction in a state where it is not pushed upward. It protrudes out of the cover 7 from the through hole 715. The second operation member 6215 may not protrude from the second through hole 715 to the outside of the cover 7 in a state where it is not pushed upward. However, considering the pushability, it is desirable that at least a part of the second operation member 6215 protrudes from the second through hole 715 to the outside of the cover 7 as in the illustrated example.

  The 3rd through-hole 713 of the 1st cover 71 is facing the receiving part 614 of the control apparatus 6 (refer FIG.1 and FIG.5A). Moreover, the 4th through-hole 714 of the 1st cover 71 is facing the display part 613 of the control apparatus 6 (refer FIG.1 and FIG.5A). That is, the control signal transmitted from the remote controller reaches the receiving unit 614 through the third through hole 713. Further, light (green light) emitted from the display unit 613 is radiated to the outside of the cover 7 through the fourth through hole 714.

  The cover 7 is fixed to the instrument body 10 by a pair of hook portions 716 of the first cover 71 and a fixing portion 722 of the second cover 72. The pair of hooks 716 are hooked on the projecting piece 130 protruding rightward from the lower end of the second side plate 13 on the left side of the instrument body 10 (see FIG. 12). The fixing portion 722 is screwed to the top plate 11 of the instrument body 10. The screw for fixing the fixing portion 722 is inserted into the screw insertion hole 723 of the fixing portion 722 and the screw insertion hole 801 provided in the main piece 80 of the presser 8, and then the top plate of the instrument body 10. 11 (refer to FIG. 12).

(3) Positional relationship between cover shape and through hole In the present embodiment, in the first direction (vertical direction), the first distance D1 from the second printed wiring board 610 to the first through hole 712 is: 2 is larger than the second distance D2 from the printed wiring board 610 to the second through hole 715 (see FIG. 1). When viewed along the first direction, the third distance D3 from the center P3 of the cover 7 to the first through hole 712 in the second direction (see the one-dot chain line A1 in FIG. 5A) is the center P3. To the second through hole 715 is smaller than the fourth distance D4. Since the first through hole 712 and the second through hole 715 have such a positional relationship, the user or the inspection operator can perform the first operation facing the first through hole 712 and the second through hole 715, respectively. It is easy to distinguish the member 6214 and the second operating member 6215. That is, when the first distance D1 and the second distance D2 are the same, or when the third distance D3 and the fourth distance D4 are the same, the positional relationship in which there is no height difference between the two through holes, the center It is easier to distinguish the two operation members than in the case where the positions are symmetrical with respect to P3. Therefore, it is possible to reduce the possibility that the operation member corresponding to the inspection operation which is not intended by the user or the inspection operator is erroneously operated, and the convenience at the time of inspection can be improved.

  In particular, in the present embodiment, the second through hole 715 has a diameter that allows the test finger to be inserted. Therefore, the user can easily recognize the second operation member 6215 provided on the premise of the pressing operation with the finger and execute the second inspection operation. The first through hole 712 has a diameter that prohibits the insertion of the test finger. Therefore, it is possible to avoid a situation in which the user accidentally presses the first operation member 6214 corresponding to the first inspection operation with a finger although the user originally intends to execute the second inspection operation.

  In the present embodiment, as shown in FIG. 1, the first cover 71 of the cover 7 is formed so as to move away from the instrument body 10 as it approaches the center P3 from both ends in the second direction (front-rear direction). Yes. In particular, the first cover 71 of the cover 7 is formed in a curved shape in which the center P3 protrudes in a direction away from the instrument body 10. Therefore, the dimensional relationship that the first distance D1 is larger than the second distance D2 can be realized with a simple structure. The second through hole 715 is provided at a position where the inclination with respect to the second printed wiring board 610 (substrate) is larger than that in the vicinity of the center P3. For this reason, the two operation members having the same shape and the same size are arranged with the surface of the base portion 621A directed downward in the same direction and at substantially the same distance from the substrate, but the second operation member 6215 is disposed. Can be easily protruded out of the cover 7. In short, compared with the case where the second operation member 6215 based on the pressing operation with the finger is arranged near the center P3 like the first operation member 6214, a part of the second operation member 6215 can be easily covered. Can protrude outside. Thus, part of the second operation member 6215 protrudes, so that the user's pushability at the time of executing the second inspection operation is improved.

  Moreover, since the 4th through-hole 714 facing the display part 613 which displays the state regarding at least 2nd inspection operation is adjacent to the 2nd through-hole 715, the relationship between 2nd inspection operation and the display part 613 is shown. It is possible to improve the convenience of inspection work.

  On the other hand, the third through hole 713 facing the receiving unit 614 is adjacent to the first through hole 712 facing the first operation member 6214. Since both the receiving unit 614 and the first switch 611 are parts that receive the execution of the first inspection operation, the first through hole 712 and the third through hole 713 are arranged adjacent to each other, thereby having a relationship. Can be increased. Therefore, the convenience of the inspection operator when performing the first inspection operation (self-inspection operation) is improved. In particular, the third through-hole 713 facing the receiving unit 614 is closest to the center P3 as compared to other through-holes as shown in the example in order to increase the reception sensitivity for the control signal transmitted from the remote controller. It is desirable to be placed in position. In other words, providing the third through hole 713 near the center P3 can improve the convenience of the operator who operates the remote controller.

  As described above, the first operation member 6214 corresponding to the first inspection operation is disposed near the center P3, and the second operation member 6215 corresponding to the second inspection operation is disposed away from the center P3. Thus, it can be said that the convenience of the inspection work for the user and the inspection worker is improved.

In the present embodiment, at least a part of the first cover 71 of the cover 7 including at least the center P3 is separated from the instrument main body 10 in the same way as the translucent cover 20 of the service lighting device 2 when viewed from the left-right direction. It is formed in an arc shape protruding in the direction. As a result, the dimensional relationship that the first distance D1 is larger than the second distance D2 can be realized with a simple structure, and the appearance of the lighting fixture 1 as a whole can be improved. However, the first cover 71 of the cover 7 may be formed in a trapezoidal shape in the vicinity of the center P3 when viewed from the left-right direction. (4) Advantages As described above, the lighting fixture 1 according to the first aspect includes the regular illumination device 2 that performs regular illumination, the emergency illumination device 3 that performs emergency illumination, the regular illumination device 2 and the emergency illumination. An instrument body 10 that houses the lighting devices 3 next to each other is provided. The emergency lighting device 3 includes an emergency light source unit 4, an emergency power supply unit 5, a control device 6, and a cover 7. The control device 6 lights the emergency light source unit 4 with the power supplied from the emergency power supply unit 5. The cover 7 has a hole 711 through which light emitted from the emergency light source unit 4 passes and covers the emergency light source unit 4 and the control device 6. The control device 6 includes a board (second printed wiring board 610), and a first switch 611 and a second switch 612 mounted on the board.
