The light receiving element 614 is configured to receive a control signal using, for example, infrared rays 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 worker who performs periodic inspection work. Note that the "control signal" referred to here is not limited to infrared rays as long as it is a signal using electromagnetic waves as a medium. The control signal may be, for example, a signal using radio waves as a medium other than infrared rays. In this case, a wireless communication antenna may be provided instead of the light receiving element 614. The light receiving element 614 is mounted between the display element 613 and the second pushbutton switch 612 on the lower surface of the second printed wiring board 610. In short, the first and second push-button switches 611, 612, the display element 613, and the light-receiving element 614 are arranged in the order of the first push-button switch 611, the display element 613, the light-receiving element 614, and the second push-button switch 612 along the front-rear direction.

The control circuit of the first circuit block 60 is configured to monitor the operating states (ON and OFF) of each of the first push button switch 611 and the second push button switch 612 through a cable. Further, the control circuit is configured to receive the transmission frame of the control signal demodulated by the light receiving element 614 through the cable. Further, the control circuit is configured to cause the display element 613 to emit light by passing current through the cable to the display element 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 front second push button switch 612 is turned on or when a transmission frame is received from the light receiving element 614. Self-inspection operation refers to stopping the charging circuit, operating the lighting circuit for a predetermined period of time (for example, 30 minutes or 60 minutes), and then stopping the lighting circuit and operating the charging circuit again. be. When performing periodic inspection work, the inspection worker causes the self-inspection operation (first inspection operation) to be performed through the second push button switch 612 or the remote controller.

Further, the control circuit is configured to perform another inspection operation (second inspection operation) different from the self-inspection operation (first inspection operation) when the rear first push button switch 611 is turned on. There is. This second inspection operation is to stop the charging circuit and operate the lighting circuit while the first push button switch 611 is in the on state. When the first push button switch 611 is turned off, the lighting circuit is stopped and the charging circuit is activated. However, it is preferable that the control circuit is configured to perform the second inspection operation even when a transmission frame instructing to perform the second inspection operation is received from the light receiving element 614. When performing inspection work, the user causes the inspection operation (second inspection operation) to be performed through the first push button switch 611.

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

The case 62 includes a first case 620 and a second case 621. The first case 620 has a bottom portion 6200 and a side wall portion 6201. The bottom portion 6200 is formed into a roughly rectangular box shape. The bottom portion 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 portion 6201 is formed into a plate shape. Side wall portion 6201 is connected to bottom portion 6200 via a hinge.

The second boss 516 is formed into a truncated conical shape having a screw hole (female thread) with an open upper end. Further, the second boss 516 is formed to rise upward from the inner surface of the outer peripheral wall 510 between the first outer wall 511 and the second inner wall 514 on the left side. The pair of protrusions 519 are formed in the shape of a truncated cone that protrudes upward at both front and rear ends on the inside (left side) of the second outer wall 512 (see FIG. 12).

The second housing 52 is formed into a roughly rectangular box shape, as shown in FIGS. 11 and 12. The second housing 52 has a bottom wall 520, a pair of first side walls 521, and a pair of second side walls 522. The bottom wall 520 is formed into a rectangular flat plate shape. A pair of first side walls 521 protrude downward from both ends (front end and rear end) of the bottom wall 520 along the longitudinal direction. A pair of second side walls 522 protrude downward from both ends (left end and right end) of the bottom wall 520 along the width direction.

A cylindrical protrusion 5200 protrudes downward from the center of the lower surface of the bottom wall 520 (see FIGS. 10 and 11). A cylindrical hole 5201 is provided inside the protrusion 5200. This hole 5201 passes through the bottom wall 520 and the protrusion 5200 in the vertical direction so as to connect the inside of the casing 5 and the outside of the casing 5 (see FIG. 10). However, this hole 5201 is closed, for example, with a member generally called a rubber plug with holes (hereinafter referred to as rubber plug 57) (see FIG. 10). The rubber stopper 57 is made of an elastic material such as silicone rubber and has a cylindrical shape. Furthermore, the rubber stopper 57 includes three holes 570 having at least one wall in the middle thereof (see FIG. 12). That is, each hole 570 of the rubber stopper 57 is configured to connect the inside of the housing 5 and the outside of the housing 5 by piercing the wall with a needle or the like.

Further, the bottom wall 520 has three bosses 5202 and four ribs 5204.

Each boss 5202 has a screw hole 5203 that opens on the top surface of the bottom wall 520 (see FIGS. 10 and 12). Two of the four ribs 5204 are formed in a prismatic shape that protrudes downward from the lower surface of the bottom wall 520 along the first side wall 521 on the front side (see FIG. 11). The remaining two ribs 5204 among the four ribs 5204 are formed in a prismatic shape that protrudes downward from the lower surface of the bottom wall 520 along the first side wall 521 on the rear side.

The left second side wall 522 of the pair of second side walls 522 has a protrusion 5220 that protrudes leftward from the lower end of the center in the front-rear direction on its outer surface (left side surface) (see FIGS. 10 and 11). ). The protrusion 5220 has a hole 5221 penetrating in the vertical direction (see FIG. 10).

Further, the second housing 52 has a fixing portion 523 and a protruding portion 524 . The fixing portion 523 is formed in a rectangular plate shape that protrudes rightward from the lower end of the right second side wall 522 of the pair of second side walls 522 (see FIG. 11). A cylindrical hole 5230 vertically passes through the center of the fixing portion 523 in the front-rear direction (see FIGS. 10 and 11). Further, approximately wave-shaped recesses 5231 are provided on both sides of the hole 5230 on the lower surface of the fixing portion 523, respectively. The protrusion portion 524 is formed in a rectangular box shape that protrudes rightward from the tip (right end) of the fixing portion 523 (see FIG. 11). Cylindrical bosses 5240 are provided at both ends in the front-rear direction at the tip (right end) of the projecting base portion 524, respectively. Each boss 5240 has a screw hole 5241 with an open top surface (see FIG. 12).

As shown in FIGS. 11 and 12, the first gasket 53 is made of an elastic material such as silicone rubber and is formed into a rectangular frame shape as a whole. The first gasket 53 has a frame portion 530, a fixing portion 531, a pair of wire holding portions 532, and a support portion 533, as shown in FIGS. 16 and 17. The frame portion 530 is formed into a rectangular frame shape with four chamfered corners. A recess 5300 is provided on the lower surface of the frame portion 530 and is recessed upward over the entire circumference. The fixing portion 531 is formed into a rectangular plate shape that protrudes inward (leftward) from the inner surface at one end (right end) of the frame portion 530 in the longitudinal direction. A semicircular protrusion 5310 protrudes inward (leftward) from the center of the fixed portion 531 in the longitudinal direction (front-back direction). A cylindrical screw insertion hole 5311 vertically passes through the longitudinal center portion of the fixing portion 531 including the protrusion 5310. Further, cylindrical fitting holes 5312 are provided on both sides of the screw insertion hole 5311 on the lower surface of the fixing part 531 (see FIG. 16). The support portion 533 protrudes downward from the inner edge of the recess 5300 on the lower surface of the frame portion 530, except for the right end portion of the frame portion 530 (the portion overlapping the fixed portion 531 when viewed from the top and bottom). The pair of wire holding parts 532 protrudes upward from both the front and rear sides of the screw insertion hole 5311 on the upper surface of the fixing part 531. Each wire holding portion 532 is formed into a columnar shape with a roughly wave-shaped bottom surface. Further, each wire holding portion 532 has a pair of holes 5320 penetrating in the axial direction (horizontal direction) and three ribs 5321 protruding from the circumferential surface of each wire holding portion 532 (see FIG. 17). ).

The second gasket 54 is made of an elastic material such as silicone rubber and is formed into a frame shape having an elliptical opening 540 in the center (see FIG. 11). However, the second gasket 54 is preferably colored black so as not to transmit light. Further, an annular peripheral wall 541 projects upward from the edge of the opening 540 on the upper surface of the second gasket 54 over the entire circumference (see FIG. 12). Further, on the upper surface of the peripheral wall 541, two ribs having a triangular cross section parallel to the vertical direction protrude so as to be lined up along the radial direction. Further, the second gasket 54 has four fitting holes 542 and two hook pieces 543. The four fitting holes 542 are arranged to surround the opening 540 and pass through the second gasket 54 in the thickness direction (vertical direction). Further, the two hook pieces 543 are formed in a hook shape and protrude upward from the right rear end and the left front end of the second gasket 54 .

The emergency lighting device 3 further includes a fixing member 56 (see FIGS. 11 and 12). The fixing member 56 is made of a rust-resistant metal plate such as a stainless steel plate. The fixing member 56 includes a pentagonal fixing piece 560 whose longitudinal direction is the front-rear direction, a pair of leg pieces 561 that protrude upward from each side of both longitudinal ends of the fixing piece 560, and an upper end of each leg piece 561. It has a pair of mounting pieces 562 that protrude from the fixing piece 560 and facing each other. A fixing hole 563 for holding a nut is provided approximately in the center of the fixing piece 560. A screw insertion hole 564 passes through one end (right end) of each mounting piece 562 (see FIG. 12).

(2.6) Operation Gasket The operation gasket 55 (sealing device) is configured to close the keyhole-shaped hole composed of the first operation hole 502 and the display hole 503, and the second operation hole 504. It is attached to the housing 51. The operating gasket 55 is made of an elastic material that transmits light, such as silicone rubber. The operation gasket 55 has a seal portion 550, a first operation portion 551, a second operation portion 552, and a transparent portion 553, as shown in FIGS. 2A and 2B. The seal portion 550, the first operation portion 551, the second operation portion 552, and the transmission portion 553 are all integrally formed. In this embodiment, the operating gasket 55 is, for example, a single molded product made of uncolored silicone rubber.

The seal portion 550 prevents water from entering the housing 5 through the first operation hole 502, display hole 503, and second operation hole 504. The seal portion 550 is formed into a roughly elliptical cylinder shape. The seal portion 550 has a first end surface 550A (one surface, that is, a lower surface) facing the inner surface of the outer peripheral wall 510 of the first housing 51, and a second end surface 550B (upper surface) facing the control device 6. There is. The first end surface 550A of the seal portion 550 is formed into a curved surface having the same radius of curvature as the surface (lower surface) of the outer peripheral wall 510 of the first housing 51. Moreover, three ribs 559 having a triangular cross section parallel to the vertical direction protrude from the outer circumferential surface of the seal portion 550 so as to be lined up at equal intervals along the vertical direction. Further, the seal portion 550 has a first through hole 554, a second through hole 555, and a display groove 556. The first through hole 554 is formed in a cylindrical shape that vertically passes through the seal portion 550 at one end of the seal portion 550 in the longitudinal direction. The second through hole 555 is formed in a cylindrical shape that vertically passes through the seal portion 550 at the other end of the seal portion 550 in the longitudinal direction. The display groove 556 is formed in the shape of a rectangular tube with an open bottom surface between the first through hole 554 and the second through hole 555 of the seal portion 550. However, a lower portion of the display groove 556 in the vertical direction is connected to the first through hole 554 (see FIG. 2B).

The seal portion 550 is formed in an asymmetrical shape in the front-rear direction when viewed along the up-down direction. In other words, the dimensional relationship is defined such that the width around the first operation section 551 in the front-rear direction is larger than the width around the second operation section 552 in the front-rear direction. Therefore, when attaching the operating gasket 55 to the first housing 51, it is possible to prevent the seal portion 550 from being accidentally fitted into the projecting wall 518 in the reverse direction.

As shown in FIG. 1, the transmitting portion 553 is arranged to face the display element 613 through the window 6217, and is configured to transmit light emitted from the display element 613. The transmitting portion 553 is constituted by the bottom wall (upper wall) of the display groove 556 in the seal portion 550 (see FIGS. 2A and 2C). In other words, by providing the display groove 556, the thickness of the transparent portion 553 in the direction in which the display element 613 and the transparent portion 553 are lined up (vertical direction) is sufficiently large compared to the thickness of the seal portion 550. It's thinner. Specifically, the thickness dimension of the transmitting portion 553 in the vertical direction is made sufficiently thinner than the dimension from the first end surface 550A to the second end surface 550B of the sealing portion 550. In short, the transmitting portion 553 is arranged at a position recessed from the first end surface 550A of the operating gasket 55 by a predetermined distance depending on the depth of the display groove 556. The larger the depth dimension of the display groove 556 is set, the smaller the thickness dimension of the transmissive part 553 becomes, so that attenuation of light emitted from the display element 613 in the transmissive part 553 can be suppressed. However, if the thickness of the transparent part 553 becomes too thin, there is a high possibility that the transparent part 553 will be damaged and lose its waterproof function. It is desirable that

Further, the transmitting section 553 is also arranged to face the light receiving element 614 through the window 6216. Therefore, it is also possible to suppress attenuation of the control signal transmitted from the remote controller.

The first operation section 551 is formed in a cylindrical shape. The first operation part 551 is accommodated in the first through hole 554 of the seal part 550 so that its axial direction is aligned in the vertical direction. The first operation section 551 is arranged between the first transmission member 6214 and the first operation hole 502 of the first housing 51. The first operation section 551 protrudes toward the first operation hole 502.

The second operating section 552 is formed in a cylindrical shape shorter than the first operating section 551. The second operation part 552 is accommodated in the second through hole 555 of the seal part 550 so that its axial direction is aligned in the vertical direction. The second operation section 552 is arranged between the second transmission member 6215 and the second operation hole 504 of the first housing 51. The second operation section 552 protrudes toward the second operation hole 504.

Further, the operating gasket 55 has a first seal portion 557 that seals the first through hole 554 and a second seal portion 558 that seals the second through hole 555 (see FIG. 2C). The first seal portion 557 and the second seal portion 558 are each formed into a hollow truncated cone shape with two open bottoms. The periphery of the large-diameter bottom surface of the first seal portion 557 is coupled to the inner circumferential surface of the first through hole 554 of the seal portion 550 . The circumferential edge of the small-diameter bottom surface of the first seal portion 557 is coupled to the circumferential surface of the first operating portion 551 . The periphery of the large-diameter bottom surface of the second seal portion 558 is coupled to the inner peripheral surface of the second through hole 555 of the seal portion 550 . The circumferential edge of the small diameter bottom surface of the second seal portion 558 is coupled to the circumferential surface of the second operating portion 552 . The tip (lower end) of the first operating portion 551 protrudes from the first through hole 554 below the first end surface 550A of the seal portion 550 (see FIG. 2B). On the other hand, the tip (lower end) of the second operating portion 552 is accommodated within the second through hole 555 and does not protrude downward from the first end surface 550A of the seal portion 550 (see FIG. 2B). Here, the first seal part 557 and the second seal part 558 are made of an elastic material (silicone rubber) and are therefore elastically deformable. Therefore, the first operating section 551 and the second operating section 552 move upward when an upward force is applied, and then when the upward force is no longer applied, the elasticity of the first seal section 557 and the second seal section 558 The force causes it to move downward and return to its initial state (the state shown in FIG. 2C).

Here, the amount by which the first operating portion 551 protrudes from the first operating hole 502 is different from the amount by which the second operating portion 552 protrudes from the second operating hole 504 . In the present embodiment, the protruding tip (lower end) of the first operation section 551 is located outside the first housing 51 than the first operation hole 502 . The protruding tip (lower end) of the second operation section 552 is located inside the first housing 51 rather than the second operation hole 504 . Further, the second operation hole 504 has a diameter that prohibits insertion of a test finger. Here, the test finger is, for example, a pseudo finger specified in Appended Table 41 (2) C of the Japanese Electrical Appliance and Material Safety Act. Since the diameter of the second operation hole 504 is defined in this manner, the second operation section 552 does not accept a push operation by a human finger. That is, in the present embodiment, the second operation section 552 is provided on the premise that the second operation section 552 can be operated by, for example, the tip of a tool for inspection work. On the other hand, the diameter of the first operating hole 502 is determined to be such that the lower end of the first operating portion 551 partially protrudes outside the first housing 51, as shown in FIG. That is, in the present embodiment, the first operation section 551 is provided on the assumption that it will be pressed by a person's finger.

Therefore, the user can easily recognize the first operation section 551, which is provided on the assumption that it will be pressed with a finger, and can execute the second inspection operation. Furthermore, since the second operation hole 504 has a diameter that prohibits the insertion of a test finger, the user may accidentally press the second operation portion 552 corresponding to the first inspection operation (self-inspection operation) with a finger. situations such as this can be reduced. In addition, the inspection worker can also easily recognize the second operation section 552, which is provided on the assumption that it will be pressed by a tool for inspection work, and can execute the first inspection operation (self-inspection operation).

Further, the transparent portion 553 is provided between the first operating portion 551 and the second operating portion 552 when the operating gasket 55 is viewed in the vertical direction. Particularly, in the transparent section 553, the first region 553A (see FIG. 2A) in the rear half facing the display element 613 that displays the state related to at least the second inspection operation is adjacent to the first operation section 551. This is due to the fact that the display element 613 and the first push button switch 611 corresponding to the second inspection operation are placed next to each other. Such an adjacent arrangement can enhance the relationship between the second inspection operation and the display element 613. Therefore, the user's convenience when performing the second inspection operation is improved. Further, by such an adjacent arrangement, it is possible to reduce the size of the emergency lighting device 3 as a whole.

On the other hand, in the transmission section 553, a second region 553B (see FIG. 2A) in the front half facing the light receiving element 614 is adjacent to the second operation section 552. This is due to the fact that the light receiving element 614 and the second push button switch 612 are placed next to each other. The light receiving element 614 and the second push button switch 612 are both parts that accept execution of the first inspection operation (self-inspection operation). Therefore, such an adjacent arrangement can improve the relationship between the light receiving element 614 and the second push button switch 612. Therefore, convenience for the inspection operator when performing the first inspection operation (self-inspection operation) is improved. Further, by such an adjacent arrangement, it is possible to reduce the size of the emergency lighting device 3 as a whole. In addition, the second region 553B facing the light receiving element 614 and the display hole 503 are arranged in the front and back direction of the first housing 51 as shown in the illustrated example in order to increase the reception sensitivity for control signals transmitted from the remote controller. It is desirable to place it near the center.

By the way, since the inside of the housing 5 which has a waterproof function is a sealed space, the gas inside the housing 5 expands due to the heat emitted from the LED module 40 (light source), and the inside of the housing 5 and the inside of the housing 5 expand. A pressure difference may occur with the outside. In other words, the internal pressure of the casing 5 may increase, and the reliability of circuit components and the like may decrease. However, since the permeable part 553 of this embodiment is made of silicone rubber, the permeable part 553 does not allow liquid to pass through but allows gas to pass therethrough. Further, since the thickness of the transparent portion 553 is sufficiently thin, gas expanded within the housing 5 is easily discharged to the outside through the thin transparent portion 553. Therefore, such a pressure difference can be effectively alleviated, and deterioration in reliability of circuit components and the like can be suppressed. Note that if the transparent part 553 is thin, even if it is not made of silicone rubber, it will deform so as to bulge outward, so that it can be expected that the pressure difference will be alleviated to some extent.

(3) Procedure for assembling the emergency lighting device Next, the procedure for assembling the emergency lighting device 3 will be explained. However, a description of the assembly work of the emergency light source unit 4 and the control device 6 and the work of attaching the emergency light source unit 4 to the support member 7 will be omitted. Further, the assembly procedures (A) to (H) described below are merely examples, and the order of some of the assembly operations may be changed.

(A) Attaching the second gasket 54 to the first housing 51 First, a worker who performs the assembly work attaches the second gasket 54 to the first housing 51. Specifically, the operator fits the four protrusions 505 provided on the lower surface of the outer peripheral wall 510 of the first housing 51 into the four fitting holes 542 of the second gasket 54 one by one.

(B) Attaching the operating gasket 55 to the first casing 51 The operator attaches the operating gasket 55 to the first casing 51 by pushing the operating gasket 55 inside the projecting wall 518 (Fig. 13 reference). Inside the projecting wall 518, three ribs 559 provided on the seal portion 550 are deformed so as to be crushed by the projecting wall 518. As a result, the inside of the protruding wall 518 is sealed by the operation gasket 55, so that the inside of the projecting wall 518 is sealed from the first operation hole 502, the second operation hole 504, and the display hole 503 provided in the outer peripheral wall 510 into the first housing 51. flooding will be suppressed. Note that the tip (lower end) of the first operating portion 551 of the operating gasket 55 protrudes from the surface (lower surface) of the outer peripheral wall 510 through the first operating hole 502 of the first housing 51 (see FIGS. 1 and 3). .

(C) Attaching the emergency light source unit 4 to the first housing 51 The operator inserts the lens body 440 of the emergency light source unit 4 into the window 501 of the first housing 51 through the opening 540 of the second gasket 54. Then, the plurality of ribs 517 of the first housing 51 are fitted into corresponding fitting grooves 72 of the plurality of fitting grooves 72 of the support member 7 (see FIG. 15). Then, the operator inserts a screw into each of the three screw insertion holes 75 of the support member 7, and inserts each screw into the corresponding screw hole of the three first bosses 515 of the first casing 51. The support member 7 is screwed to the first housing 51 by screwing. At this time, the two ribs provided on the upper surface of the peripheral wall 541 of the second gasket 54 are crushed and deformed by the outer flange 441 of the lens 44 and the peripheral edge portion of the window 501 in the outer peripheral wall 510. As a result, the window 501 of the first housing 51 and the outer flange 441 of the lens 44 are sealed by the second gasket 54, so the gap between the holder 41 and the window 501 of the first housing 51 is closed, and the window 501 of the first housing 51 is sealed. 501 into the first casing 51 is suppressed. Note that the first operating portion 551, the second operating portion 552, and the transparent portion 553 of the operating gasket 55 face the insertion hole 70 of the support member 7 (see FIG. 15).

(D) Attaching the first gasket 53 to the first housing 51 The operator installs the pair of first inner walls 513 and the pair of first inner walls 513 of the first housing 51 into the recess 5300 of the frame 530 of the first gasket 53. 2. Press fit the upper end portions of each of the inner walls 514. Furthermore, the operator press-fits the tip of the second boss 516 of the first housing 51 into the screw insertion hole 5311 of the fixing part 531 of the first gasket 53, and inserts the tip of the second boss 516 into each fitting hole 5312 of the fixing part 531. Each protrusion 519 of one housing 51 is fitted. In this way, the first gasket 53 is attached to the first housing 51 (see FIG. 15).

(E) Connection to the control device The operator press-fits the pair of power supply wires 80 for the regular power supply into the holes 5320 of the rear wire holding portion 532 of the two wire holding portions 532 of the first gasket 53. (See FIGS. 18 and 19). Further, the operator press-fits and holds the pair of electric wires 81 for the emergency power source into the holes 5320 of the front electric wire holding part 532 of the two electric wire holding parts 532 of the first gasket 53 (see FIG. 18). ). The operator connects one end of the pair of power supply lines 80 to the input terminal block 603 of the control device 6 . Further, the operator electrically connects one end of the pair of electric wires 81 to the receiving connector 64 of the control device 6 . Here, the control device 6 is housed in the housing 5 at one end (left end) in the longitudinal direction of the housing 5. Therefore, the emergency lighting device 3 can secure a space for wiring the power line 80 and the electric wire 81 between the casing 5 and the control device 6 (see FIG. 19). This space for wiring allows the emergency lighting device 3 to improve the workability of connecting the wires to the control device 6.

(F) Incorporation of the control device 6 into the second casing 52 The operator accommodates the control device 6 inside the second casing 52. At this time, the control device 6 is supported by the plurality of ribs 5204 of the second housing 52 (see FIG. 13).

(G) Assembling the casing 5 The operator inserts the tip (upper end) of the first boss 515 of the first casing 51 into the hole 5230 of the fixing part 523 of the second casing 52, and The tip (upper end) of the second boss 516 of No. 51 is inserted into the hole 5221 of the protrusion 5220 of the second housing 52 (see FIG. 13). At this time, the two wire holding parts 532 of the first gasket 53 are fitted into corresponding recesses 5231 of the two recesses 5231 of the fixing part 523 of the second housing 52. Then, the operator inserts a screw into the hole 5230 of the fixing part 531 from the top side of the second housing 52, and screws the screw into the screw hole of the first boss 515. Furthermore, the operator inserts a screw into the hole 5221 of the protrusion 5220 from the top side of the second housing 52, and screws the screw into the screw hole of the second boss 516. That is, the first casing 51 and the second casing 52 are screwed together with two screws to form the casing 5. Here, the pair of first inner walls 513 and the pair of second inner walls 514 of the first housing 51, the pair of first side walls 521, the pair of second side walls 522, and the fixing part 523 of the second housing 52 are as follows: The frame portion 530 of the first gasket 53 seals. In addition, the three ribs 5321 of the pair of wire holding parts 532 of the first gasket 53 are deformed so as to be crushed by the recesses 5231 of the fixing part 523 of the second casing 52, so that the second casing 52 A pair of recesses 5231 are sealed. Therefore, the first gasket 53 suppresses water intrusion from the interface between the first housing 51 and the second housing 52.

(H) Attaching the fixing member 56 to the casing 5 The operator places the pair of mounting pieces 562 of the fixing member 56 over the protrusion part 524 of the second casing 52, and places the screw insertion hole of each mounting piece 562. 564 is screwed into the screw hole 5241 of the corresponding boss 5240 of the two bosses 5240 of the projecting base portion 524. The fixing member 56 is attached to the housing 5 with the fixing piece 560 facing the protrusion 524 of the second housing 52 (see FIGS. 3 to 6).

The assembly of the emergency lighting device 3 is completed through the steps described above.

Here, the first operation part 551 of the operation gasket 55 faces the first transmission member 6214 of the control device 6, and the second operation part 552 of the operation gasket 55 faces the second transmission member 6215 of the control device 6. They are facing each other (see Figure 1). Therefore, when the first operating section 551 that moves upward pushes the first transmission member 6214 upward, the push button of the first push-button switch 611 is pushed by the first transmission member 6214, and the first push-button switch 611 is turned on. Furthermore, when the second operation section 552 that moves upward pushes the second transmission member 6215 upward, the push button of the second push button switch 612 is pushed by the second transmission member 6215, and the second push button switch 612 is turned on. In other words, the operation gasket 55 seals the inside of the projecting wall 518 while allowing the first transmission member 6214 and the second transmission member 6215 of the control device 6 to be pushed and operated. Further, the transparent portion 553 of the operation gasket 55 faces the display element 613 and the light receiving element 614 through the insertion hole 70 of the support member 7 and two windows 6216 and 6217 provided in the case 62 of the control device 6. (See Figure 1). Therefore, the light (green light) emitted by the display element 613 is radiated out of the case 62 through the window 6217, and then transmitted through the transmission portion 553 of the operating gasket 55 and radiated out of the casing 5. Further, the control signal transmitted from the remote controller passes through the transparent portion 553 of the operation gasket 55 and then reaches the light receiving element 614 through the window 6216 of the case 62. Note that since the transparent portion 553 is formed sufficiently thinner than the seal portion 550 of the operation gasket 55, attenuation when the light emitted by the display element 613 and the control signal transmitted from the remote controller is transmitted through the transparent portion 553 is reduced. can be suppressed.

The housing 5 of the emergency lighting device 3 is configured to have a waterproof function by sealing the first housing 51 and the second housing 52 with the first gasket 53 as described above. Further, the emergency lighting device 3 includes a window 501 provided in the first housing 51 for extracting light emitted from the emergency light source unit 4, and a second gasket 54 for sealing the window 501. . Therefore, the emergency lighting device 3 can easily be provided with a structure for extracting the light emitted by the LED module 40 of the emergency light source unit 4 from the casing 5 having a waterproof function.

Further, the support member 7 restricts displacement of the operating gasket 55 along the direction in which the first housing 51 and the support member 7 are lined up (vertical direction). That is, since displacement of the operating gasket 55 is restricted by the support member 7, it is prevented from falling off from the projecting wall 518 of the first housing 51.

Furthermore, the second gasket 54 closes the gap between the window 501 and the holder 41 by sealing the window 501 of the first housing 51 and the lens 44 of the emergency light source unit 4. Therefore, the emergency lighting device 3 can suppress water from entering through the gap between the window 501 and the holder 41.

Here, the support portion 533 of the first gasket 53 is disposed within the housing 5 between each first inner wall 513 of the first housing 51 and the case 62 of the control device 6 to support the control device 6. (See Figure 1). Therefore, since the support portion 533 of the first gasket 53 supports the control device 6, shaking of the control device 6 within the housing 5 can be suppressed.

In particular, in this embodiment, the operating gasket 55 has not only a waterproof function but also a function of pressing the first push button switch 611 and the second push button switch 612 and a function of transmitting light from the display element 613. . Therefore, an increase in the number of parts can be suppressed.

Next, the assembly procedure of the lighting fixture 1 will be explained. However, a description of the work of attaching the emergency power supply unit 9 to the appliance main body 10 will be omitted. Furthermore, the assembly procedures (I) to (K) described below are merely examples, and the order of some of the assembly operations may be changed.

(I) Attaching the emergency lighting device 3 to the appliance body 10 Before attaching the regular lighting device 2, the worker attaches the emergency lighting device 3 to the appliance body 10. First, the operator accommodates the second casing 52 of the casing 5 of the emergency lighting device 3 into the appliance main body 10 . Next, the operator inserts screws into each of the three screw insertion holes 110 (see FIG. 9) provided in the top plate 11 from the top side of the top plate 11 of the instrument main body 10, and tightens each screw. It is screwed into the screw holes 5203 of the three bosses 5202 provided on the bottom wall 520 of the second housing 52. That is, the emergency lighting device 3 is screwed to the top plate 11 of the appliance main body 10 with three screws.

(J) Connection of control device 6 The operator connects the two electric wires 81 held in the electric wire holding part 532 in front of the first gasket 53 and the connector provided on the electric cable of the emergency power supply unit 9. Connect the wires (see Figure 18). However, the two power wires 80 (see FIGS. 18 and 19) held in the wire holding part 532 behind the first gasket 53 are electrically connected to the power wire of the regular power source during construction of the lighting fixture 1. be done.

(K) Attaching the regular lighting device 2 to the fixture main body 10 The operator inserts the upper part of the regular lighting device 2 (the part above the second fixing part 241 of the two fixtures 24) into the fixture main body 10. . Then, the operator inserts the shaft of the driver into the recess 2215 of the cover part 2214 of the right end member 221, passes the shaft through the hole 2216 provided in the bottom wall of the recess 2215, and inserts the shaft into the screw insertion hole 243 of the second fixing part 241. Tighten the mounting screw inserted into the When the operator tightens the mounting screw using a screwdriver, the mounting screw is screwed into the screw hole 131 of the mounting piece 130 on the right side of the instrument body 10. As a result, the second fixing portion 241 of the right fixture 24 is screwed to the right attachment piece 130 of the instrument body 10. Next, the operator inserts the shaft of the driver into the recess 2215 of the cover part 2214 of the left end member 221, passes through the hole 2216 provided in the bottom wall of the recess 2215, and inserts the shaft into the screw insertion hole of the second fixing part 241. Tighten the mounting screw inserted into 243. When the operator tightens the mounting screw using a driver, the mounting screw is screwed into the nut held in the fixing hole 563 of the fixing member 56. As a result, the second fixing portion 241 of the left fixture 24 is screwed to the fixing piece 560 of the fixing member 56. Finally, the operator blindfolds the operator by covering the opening of the recess 2215 exposed on the surface of the cover part 2214 with tape or the like. In this way, the regular lighting device 2 is attached to the fixture main body 10, thereby completing the assembly of the lighting fixture (see FIG. 7).

(4) Modification Examples Some modification examples are listed below. In the following, the embodiment described above will be referred to as a "basic example". The modified examples described below can also be applied in appropriate combination with the basic example described above.

In the basic example, since the display groove 556 is provided on the first end surface 550A (lower surface) of the seal section 550, the transparent section 553 is arranged at a recessed position a predetermined distance from the first end surface 550A. There is. However, the present invention is not limited to this, and the display groove 556 may be provided on the second end surface 550B (upper surface) of the seal portion 550, and the surface of the transparent portion 553 may be flush with the first end surface 550A (lower surface). In this case, compared to the basic example, the visible range of the light emitted from the display element 613 is expanded, so convenience is improved. However, since there is an increased possibility that the transparent part 553 will be damaged due to a person's finger or the like coming into contact with the transparent part 553, the basic example is preferable when waterproofing is important.

In the basic example, the number of pushbutton switches is two (first pushbutton switch 611 and second pushbutton switch 612), but there may be only one or three or more pushbutton switches. Furthermore, depending on the number of pushbutton switches, the number of operation parts of the operation gasket 55 may be one, or three or more.

In the basic example, the operating gasket 55 is made of uncolored silicone rubber, but may be partially colored. However, at least the transmitting portion 553 is desirably uncolored in order to transmit light.

In the basic example, the seal portion 550 of the operating gasket 55 has three ribs 559 on its outer peripheral surface. The three ribs 559 are crushed and deformed by the projecting wall 518 of the first casing 51, so that the inside of the first casing 51 is moved from the first operation hole 502, the second operation hole 504, and the display hole 503. Flooding into the area has been suppressed. However, the present invention is not limited to this, and instead of having the three ribs 559, the seal portion 550 of the operating gasket 55 may have a first flange protruding outward from the periphery of the second end surface 550B (upper surface). In this case, the first flange is pressed against the upper edge of the projecting wall 518, thereby suppressing water from entering the first housing 51. Further, the seal portion 550 of the operation gasket 55 has one or more holes formed on the first end surface 550A (lower surface) side so as to correspond to the first operation hole 502, the second operation hole 504, and the display hole 503, respectively. It may further include a second flange in addition to the first flange. In this case, the second flange is pressed against the periphery of the corresponding hole from the outside of the first housing 51, thereby suppressing water intrusion into the first housing 51. However, even if only the first flange is provided, water intrusion can be sufficiently suppressed.

(5) Advantages As explained above, the emergency lighting device 3 according to the first aspect includes the emergency light source unit 4, the control device 6 for lighting the emergency light source unit 4, and the emergency light source unit 4 and the control device 6 for lighting the emergency light source unit 4. It includes a casing 5 that houses the device 6 and a sealing device (operating gasket 55). The control device 6 includes a push button switch (a first push button switch 611 or a second push button switch 612) for receiving an operation input, and a display element 613 that emits display light. The housing 5 has a first hole and a second hole (first operation hole 502 and display hole 503, or second operation hole 504 and display hole 503).

According to the second aspect, the relationship between the push button switch facing the first hole and the display element 613 facing the second hole can be improved. That is, for example, when the control device 6 executes a certain inspection operation in response to a push button switch and displays the inspection result or operation status on the display element 613, the first hole and the second hole are Providing it as a hole enhances the above relationship. Therefore, convenience is improved.

Regarding the emergency lighting device 3 according to the third aspect, in the first aspect or the second aspect, the sealing device (operating gasket 55) is preferably made of silicone rubber.

According to the third aspect, a flexible sealing device can be provided. Particularly, for example, when a person presses the operating section with a finger, a good contact feeling can be provided.

According to the fourth aspect, it is possible to suppress the light emitted from the display element 613 from attenuating in the transmitting portion 553. For example, even if the gas inside the housing 5 expands due to the heat emitted from the light source of the emergency light source unit 4 and a pressure difference occurs between the inside and outside of the housing 5, this thin transparent part 553 can be deformed to bulge outward to alleviate the pressure difference. Therefore, it is possible to suppress deterioration in reliability of circuit components and the like due to pressure differences. In particular, when the permeable portion 553 is made of, for example, silicone rubber, the expanded gas can be discharged to the outside, so that the pressure difference can be more effectively alleviated.

Regarding the emergency lighting device 3 according to the fifth aspect, in the fourth aspect, it is preferable that the seal portion 550 has one surface (first end surface 550A) facing the inner surface of the casing 5.

It is preferable that the transparent part 553 is disposed at a recessed position a predetermined distance from one surface of the seal part 550. According to the sixth aspect, it is possible to reduce the situation where a person's finger or the like comes into contact with the transparent part 553 and the transparent part 553 is damaged. In other words, it is possible to prevent the waterproof function from deteriorating.

Regarding the emergency lighting device 3 according to the seventh aspect, in any one of the first to sixth aspects, the control device 6 receives the control signal using electromagnetic waves as a medium through the transmission section 553. It is preferable to further include a portion (light receiving element 614). According to the seventh aspect, the control device 6 can perform a predetermined inspection operation in response to receiving a control signal, for example. Furthermore, since the control signal is received through the transmission section 553, attenuation of the control signal can be suppressed. In particular, since the structure is such that both the light from the display element 613 and the control signal pass through the transmission section 553, it also contributes to miniaturization of the emergency lighting device 3 as a whole.

Regarding the emergency lighting device 3 according to the eighth aspect, in any one of the first to seventh aspects, the control device 6 may include a first push button switch 611 and a second push button switch 612. preferable.

It is preferable that the housing 5 further includes a third hole (second operation hole 504) at a position facing the second push button switch 612. The sealing device (operation gasket 55) includes a first operation section 551 for pressing the first push button switch 611 and a second operation section 552 for pressing the second push button switch 612 as the operation sections. It is preferable to have the following. The sealing device is preferably attached to the housing 5 so as to close the first hole (first operation hole 502), second hole (display hole 503), and third hole.

It is preferable that the seal portion 550 prevents water from entering the housing 5 through the first hole, the second hole, and the third hole. It is preferable that the seal portion 550, the first operation portion 551, the second operation portion 552, and the transmission portion 553 are formed integrally. It is preferable that the first operating section 551 and the second operating section 552 protrude toward the first hole and the third hole, respectively. It is preferable that the amount of protrusion of the first operation section 551 is different from the amount of protrusion of the second operation section 552.

According to the eighth aspect, the first operating section 551 and the second operating section 552 can be easily distinguished from the difference in the amount of protrusion. In particular, even if the control device 6 performs different operations depending on the operation on the first operation section 551 and the operation on the second operation section 552, an unintended operation may be performed due to pressing the wrong operation section. It is possible to reduce the number of situations where this happens.

Regarding the emergency lighting device 3 according to the ninth aspect, in the eighth aspect, the first operation part 551 has a protruding tip located outside the casing 5 than the first hole (first operation hole 502). It is preferable to do so. It is preferable that the protruding tip of the second operating portion 552 is located inside the housing 5 than the third hole (second operating hole 504).

According to the ninth aspect, it is possible to more easily distinguish between the first operating section 551 and the second operating section 552. In particular, since the tip of the first operating section 551 is located outside the first hole of the casing 5, the user is aware that the first operating section 551 is provided with the assumption that it will be operated by a human finger. can be easily recognized. Therefore, convenience is improved.
