The display groove 556 is formed in a square tubular shape with an open lower surface between the first through hole 554 and the second through hole 555 of the main body 550. However, the lower portion of the display groove 556 in the vertical direction is connected to the first through hole 554 (see FIG. 12B). The transmission portion 553 is composed of a bottom wall (upper wall) of the display groove 556 in the main body 550 (see FIGS. 12A and 12C).

The first operation unit 551 is formed in a columnar shape. The first operation unit 551 is housed in the first through hole 554 of the main body 550 so that its axial direction is aligned in the vertical direction. The second operation unit 552 is formed in a columnar shape shorter than that of the first operation unit 551. The second operation unit 552 is housed in the second through hole 555 of the main body 550 so that its axial direction is aligned in the vertical direction. Further, the third 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. 12C). The first seal portion 557 and the second seal portion 558 are each formed in a hollow truncated cone shape with two open bottom surfaces. The peripheral edge of the large-diameter bottom surface of the first seal portion 557 is connected to the inner peripheral surface of the first through hole 554 of the main body 550. The peripheral edge of the small diameter bottom surface of the first seal portion 557 is coupled to the peripheral surface of the first operation portion 551. The peripheral edge 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 main body 550. The peripheral edge of the small diameter bottom surface of the second seal portion 558 is coupled to the peripheral surface of the second operation portion 552. The tip (lower end) of the first operation unit 551 protrudes from the first through hole 554 below the lower surface of the main body 550 (see FIG. 12B). On the other hand, the tip (lower end) of the second operation unit 552 fits in the second through hole 555 and does not protrude downward from the lower surface of the main body 550 (see FIG. 12B). Here, since the first seal portion 557 and the second seal portion 558 are made of an elastic material (silicone rubber), they can be elastically deformed. Therefore, the first operation unit 551 and the second operation unit 552 move upward when an upward force is applied, and then the elasticity of the first seal unit 557 and the second seal unit 558 when no upward force is applied. It moves downward by force and returns to the initial state (the state shown in FIG. 12C).

The emergency lighting device 3 further includes a fixing member 56 (see FIGS. 5 and 6). The fixing member 56 is formed of a metal plate that does not easily rust, such as a stainless steel plate. The fixing member 56 includes a pentagonal fixing piece 560 having a longitudinal direction in the front-rear direction, a pair of leg pieces 561 projecting upward from both sides of the fixing piece 560 in the longitudinal direction, and an upper end of each leg piece 561.

A fixing hole 563 for holding the nut is provided substantially in the center of the fixing piece 560. A screw insertion hole 564 penetrates one end (right end) of each mounting piece 562 (see FIG. 6).

Next, the procedure for assembling the emergency lighting device 3 will be described. However, the description of the work of assembling 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 (1) to (8) described below are merely examples, and the order of some assembly operations may be changed.

(1) Attachment of the Second Gasket 54 to the First Housing 51 First, the operator performing the assembly work attaches the second gasket 54 to the first housing 51. Specifically, the operator fits the four fitting holes 542 of the second gasket 54 into the four protrusions 505 provided on the lower surface of the outer peripheral wall 510 of the first housing 51 one by one.

(2) Attaching the Third Gasket 55 to the First Housing 51 A worker attaches the third gasket 55 to the first housing 51 by pushing the third gasket 55 inside the protruding wall 518 (FIG. 7). reference). Inside the protrusion 518, the three ribs 559 provided on the main body 550 are deformed so as to be crushed by the protrusion 518. As a result, since the inside of the protruding wall 518 is sealed by the third gasket 55, the first operation hole 502, the second operation hole 504, and the display hole 503 provided in the outer peripheral wall 510 are inserted into the first housing 51. Inundation is suppressed. The tip (lower end) of the first operation portion 551 of the third gasket 55 projects from the surface (lower surface) of the outer peripheral wall 510 through the first operation hole 502 of the first housing 51 (see FIG. 13).

(3) Attaching the Emergency Light Source Unit 4 to the First Housing 51 An 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. In addition, the plurality of ribs 517 of the first housing 51 are fitted into the corresponding fitting grooves 72 of the plurality of fitting grooves 72 of the support member 7 (see FIG. 9). Then, the operator inserts screws into each of the three screw insertion holes 75 of the support member 7, and inserts each screw into the corresponding screw hole among the screw holes of the three first bosses 515 of the first housing 51. By screwing, the support member 7 is screwed to the first housing 51. At this time, the two ribs provided on the upper surface of the peripheral wall 541 of the second gasket 54 are deformed so as to be crushed by the outer flange portion 441 of the lens 44 and the peripheral edge portion of the window 501 on the outer peripheral wall 510. As a result, the window 501 of the first housing 51 and the outer flange portion 441 of the lens 44 are sealed by the second gasket 54, so that the gap between the holder 41 and the window 501 of the first housing 51 is closed and the window is closed. Water intrusion from 501 into the first housing 51 is suppressed. The first operation portion 551, the second operation portion 552, and the transmission portion 553 of the third gasket 55 face the insertion hole 70 of the support member 7 (see FIG. 9).

(4) Attaching the 1st Gasket 53 to the 1st Housing 51 A worker attaches a pair of 1st inner walls 513 and a pair of first housings 51 to a recess 5300 of a frame portion 530 of the 1st gasket 53. 2 Press-fit each upper end portion of the inner wall 514. Further, the operator press-fits the tip portion of the second boss 516 of the first housing 51 into the screw insertion hole 5311 of the fixing portion 531 of the first gasket 53, and inserts the tip portion into each fitting hole 5312 of the fixing portion 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. 9).

(5) Wiring to the control device The operator press-fits the pair of power supply lines 80 for the regular power supply into the hole 5320 of the rear wire holding portion 532 of the two wire holding portions 532 of the first gasket 53. Hold (see FIGS. 18 and 19). Further, the operator press-fits and holds the pair of electric wires 81 for the emergency power supply into the hole 5320 of the front electric wire holding portion 532 of the two electric wire holding portions 532 of the first gasket 53 (see FIG. 18). ). The operator connects one end of the pair of power 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 side connector 64 of the control device 6. Here, the control device 6 is brought close to one end (left end) in the longitudinal direction of the housing 5 and housed in the housing 5. Therefore, the emergency lighting device 3 can secure a space for wiring the power supply line 80 and the electric wire 81 between the housing 5 and the control device 6 (see FIG. 19). With this wiring space, the emergency lighting device 3 can improve the workability of the connection work to the control device 6.

(6) Incorporation of the control device 6 into the second housing 52 The worker accommodates the control device 6 inside the second housing 52. At this time, the control device 6 is supported by a plurality of ribs 5204 of the second housing 52 (see FIG. 7).

(7) Assembling the housing 5 The worker inserts the tip (upper end) of the first boss 515 of the first housing 51 into the hole 5230 of the fixing portion 523 of the second housing 52, and the first housing The tip (upper end) of the second boss 516 of 51 is inserted into the hole 5221 of the protrusion 5220 of the second housing 52 (see FIG. 7). At this time, the two wire holding portions 532 of the first gasket 53 are fitted into the corresponding recesses 5231 of the two recesses 5231 of the fixing portion 523 of the second housing 52. Then, the operator inserts a screw into the hole 5230 of the fixing portion 531 from the upper surface side of the second housing 52, and screws the screw into the screw hole of the first boss 515. Further, the operator inserts a screw into the hole 5221 of the protrusion 5220 from the upper surface side of the second housing 52, and screws the screw into the screw hole of the second boss 516. That is, the first housing 51 and the second housing 52 are screwed together by two screws to form the housing 5. Here, the pair of the first inner wall 513 and the pair of the second inner wall 514 of the first housing 51, and the pair of the first side wall 521, the pair of the second side wall 522, and the fixing portion 523 of the second housing 52 are It is sealed by the frame portion 530 of the first gasket 53. Further, the three ribs 5321 of the pair of electric wire holding portions 532 of the first gasket 53 are deformed so as to be crushed by the recess 5231 of the fixing portion 523 of the second housing 52, so that the second housing 52 A pair of recesses 5231 are sealed. Therefore, the infiltration of water from the interface between the first housing 51 and the second housing 52 is suppressed by the first gasket 53.

(8) Attaching the fixing member 56 to the housing 5 The operator puts a pair of mounting pieces 562 of the fixing member 56 on the abutment portion 524 of the second housing 52, and screw insertion holes for each mounting piece 562. The screw inserted through 564 is screwed into the screw hole 5241 of the corresponding boss 5240 of the two bosses 5240 of the abutment portion 524. The fixing member 56 is attached to the housing 5 so that the fixing piece 560 faces the abutment portion 524 of the second housing 52 (see FIGS. 13 to 16).

The assembly of the emergency lighting device 3 is completed by the above procedure.

Here, the first operation unit 551 of the third gasket 55 faces the first operation member 6214 of the control device 6, and the second operation unit 552 of the third gasket 55 meets the second operation member 6215 of the control device 6. They are facing each other (see FIG. 17). Therefore, when the first operation unit 551 moving upward pushes the first operation member 6214 upward, the push button of the push button switch 611 is pushed by the first operation member 6214, and the push button switch 611 is turned on. Further, when the second operation unit 552 moving upward pushes the second operation member 6215 upward, the push button of the push button switch 612 is pushed by the second operation member 6215, and the push button switch 612 is turned on. That is, the third gasket 55 seals the inside of the protruding wall 518 while allowing the first operating member 6214 and the second operating member 6215 of the control device 6 to be pushed and operated. Further, the transmission portion 553 of the third gasket 55 faces the display element 613 and the light receiving element 614 through the insertion holes 70 of the support member 7 and the two windows 6216 and 6217 provided in the case 62 of the control device 6. (See Fig. 17). Therefore, the light (green light) emitted by the display element 613 is radiated to the outside of the case 62 through the window 6217, and then is radiated to the outside of the housing 5 through the transmitting portion 553 of the third gasket 55. Further, the control signal transmitted from the remote controller reaches the light receiving element 614 through the window 6216 of the case 62 after passing through the transmission portion 553 of the third gasket 55. Since the transmitting portion 553 is formed to be sufficiently thinner than the main body 550 of the third gasket 55, the light emitted from the display element 613 and the control signal transmitted from the remote controller are attenuated when passing through the transmitting portion 553. It 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 is provided with a window 501 in the housing 5 for taking out the light radiated from the emergency light source unit 4, and has a second gasket 54 for sealing the window 501. Therefore, the emergency lighting device 3 can be easily provided with a structure for extracting the light radiated by the LED module 40 of the emergency light source unit 4 from the housing 5 having a waterproof function.

Further, the support member 7 regulates the displacement of the third gasket 55 along the direction (vertical direction) in which the first housing 51 and the support member 7 are arranged. That is, since the displacement of the third gasket 55 is regulated by the support member 7, the third gasket 55 is prevented from falling off from the protrusion 518 of the first housing 51.

Further, 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 intrusion from the gap between the window 501 and the holder 41.

Here, the support portion 533 of the first gasket 53 is arranged in 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 FIG. 17). Therefore, by supporting the control device 6 by the support portion 533 of the first gasket 53, it is possible to suppress the rattling of the control device 6 in the housing 5.

Next, the procedure for assembling the lighting fixture 1 will be described. However, the description of the work of attaching the emergency power supply unit 9 to the instrument main body 10 will be omitted. Further, the assembly procedures (1) to (3) described below are merely examples, and the order of some assembly operations may be changed.

(1) Attaching the Emergency Lighting Device 3 to the Instrument Body 10 The operator attaches the emergency lighting device 3 to the appliance body 10 before attaching the regular lighting device 2. First, the operator accommodates the second housing 52 of the housing 5 of the emergency lighting device 3 in the fixture main body 10. Subsequently, the operator inserts screws into each of the three screw insertion holes 110 (see FIG. 3) provided in the top plate 11 from the upper surface side of the top plate 11 of the instrument main body 10, and inserts 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 fixture main body 10 by three screws.

(2) Wiring of the control device 6 The operator connects the two electric wires 81 held by the electric wire holding portion 532 in front of the first gasket 53 and the connector provided on the electric cable of the emergency power supply unit 9. Connect (see FIG. 18). However, the two power supply lines 80 (see FIGS. 18 and 19) held by the electric wire holding portion 532 behind the first gasket 53 are electrically connected to the power supply line of the regular power supply during the construction of the luminaire 1. Will be done.

(3) Installation of the regular lighting device 2 on the fixture main body 10 The operator inserts the upper portion of the regular lighting device 2 (the portion above the second fixing portion 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 portion 2214 of the right end member 221 and passes the screw insertion hole 243 of the second fixing portion 241 through the hole 2216 provided in the bottom wall of the recess 2215. Tighten the mounting screw that is inserted into. 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 fitting 24 is screwed to the right mounting piece 130 of the instrument body 10. Subsequently, the operator inserts the shaft of the driver into the recess 2215 of the cover portion 2214 of the left end member 221 and inserts the screw insertion hole of the second fixing portion 241 through the hole 2216 provided in the bottom wall of the recess 2215. Tighten the mounting screw inserted in 243. When the operator tightens the mounting screw using a screwdriver, 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 fitting 24 is screwed to the fixing piece 560 of the fixing member 56. Finally, the operator closes the mouth of the recess 2215 exposed on the surface of the cover portion 2214 with tape or the like to blindfold it. In this way, the assembly of the lighting fixture is completed by attaching the regular lighting device 2 to the fixture main body 10 (see FIG. 1).

Next, the structure of the recess 500 of the emergency lighting device 3 will be described with reference to FIGS. 13, 20, and 21.

The bottom of the recess 500 has an inclined surface 506 that inclines in the direction of travel (downward) of light as it moves away from the edge of the window 501 over the entire circumference of the window 501. The inclined surface 506 is formed so as to have a higher reflectance than the surface other than the inclined surface 506 on the surface (lower surface) of the outer peripheral wall 510. For example, it is preferable that the inclined surface 506 is mirror-finished by polishing the bottom of the recess 500.

Here, in the emergency lighting device described in Patent Document 1, since both side portions of the lens along the short side direction of the cover are cut out, the light distributed by the lens in the short side direction of the cover. It was difficult to irradiate the light radiated to the bottom of the instrument body.

On the other hand, a reflecting surface (inclined surface 506) of the emergency lighting device 3 is provided around the lens 44 over the entire circumference. Therefore, the lighting fixture 1 reflects the light traveling in the lateral direction of the fixture main body 10 on the inclined surface 506 under the light distribution control by the lens 44, thereby suppressing the narrowing of the range of emergency lighting and the illuminance directly below. Can be improved.

Further, the lens 44 has a so-called bat wing-like light distribution characteristic in which the irradiation range in the lateral direction (second direction D2) of the instrument main body 10 is wider than that in the longitudinal direction (first direction D1) of the instrument main body 10. Is configured to have. Then, the inclined surface 506 has an inclined angle φ in the second direction D2 rather than an inclined angle φ (= φ1) in the first direction D1 with respect to a virtual plane (reference plane S1) parallel to the first direction D1 and the second direction D2. (= Φ2) is configured to be larger (see FIGS. 13, 20, and 21). Therefore, the amount of light reflected by the inclined surface 506 adjacent to the lens 44 along the second direction D2 is larger than the amount of light reflected by the inclined surface 506 adjacent to the lens 44 along the first direction D1. As a result, the luminaire 1 can further improve the illuminance directly underneath while suppressing the narrowing of the range of emergency lighting.

Further, the inclined surface 506 is configured so that the shape in the cross section perpendicular to the reference surface S1 is straight (see FIGS. 20 and 21). Therefore, the luminaire 1 has an inclined surface on the first housing 51 as compared with the case where the shape of the cross section perpendicular to the reference surface S1 of the inclined surface 506 is formed to be a curve such as a parabola or an arc. It is possible to improve workability when forming the 506.

As described above, the luminaire 1 is a long luminaire 2 that supports a long luminaire 2 that performs regular lighting, an emergency luminaire 3 that performs emergency illuminating, and a long luminaire 2 and an emergency luminaire 3. It has an instrument body 10. The appliance main body 10 is configured to support the regular lighting device 2 and the emergency lighting device 3 side by side along the longitudinal direction of the regular lighting device 2. The emergency lighting device 3 includes an emergency light source unit 4 and a housing 5 that houses the emergency light source unit 4. The emergency light source unit 4 includes a solid-state light source (LED module 40) and a lens 44 that controls the light distribution so as to expand the irradiation range of the light emitted from the LED module 40. The housing 5 has a recess 500 and a window 501 that opens to the bottom of the recess 500 through which the lens 44 is inserted. The bottom of the recess 500 has an inclined surface 506 that inclines toward the front (downward) of the window 501 as it moves away from the edge of the window 501 over the entire circumference of the window 501. The inclined surface 506 is configured to reflect light whose light distribution is controlled by the lens 44.

The lighting fixture 1 is configured as described above, and the light distribution is controlled by the lens 44 to reflect the light traveling in the lateral direction of the fixture main body 10 to the inclined surface 506, thereby suppressing the narrowing of the range of emergency lighting. At the same time, it is possible to improve the illuminance directly underneath.

Further, in the lighting fixture 1, the lens 44 is configured to have a wider irradiation range in the second direction D2, which is the lateral direction of the fixture main body 10, than in the first direction D1 which is the longitudinal direction of the fixture main body 10. Is preferable. The inclined surface 506 is configured so that the inclination angle φ with respect to the virtual plane (reference surface S1) parallel to the first direction D1 and the second direction D2 is gradually increased from the first direction D1 to the second direction D2. Is preferable.

If the luminaire 1 is configured as described above, the amount of light reflected by the inclined surface 506 adjacent to the lens 44 along the second direction D2 is the inclined surface 506 adjacent to the lens 44 along the first direction D1. It is more than the amount of light reflected by. As a result, the luminaire 1 can further improve the illuminance directly underneath while suppressing the narrowing of the range of emergency lighting.

Further, in the luminaire 1, the inclined surface 506 is preferably configured so that the shape in the cross section perpendicular to the reference surface S1 is straight.

If the luminaire 1 is configured as described above, the housing is configured so that the shape of the cross section perpendicular to the reference surface S1 of the inclined surface 506 is a curve such as a parabola or an arc. It is possible to improve workability when forming the inclined surface 506 on the 5.

Furthermore, in the luminaire 1, it is preferable that the surface of the housing 5 including the recess 500 is formed in a curved surface shape that projects in the same direction (downward) as the traveling direction of light.

If the luminaire 1 is configured as described above, the housing 5 can be slimmed down.
