[0034] The decorative frame 35 also has, on the front side, a surface portion 68 whose cross section in the width direction is formed into a convex curved surface that protrudes downward so as to be continuous with the surface shape of the protruding region 12b of the light source unit 12.

[0035] The rear side of the surface portion 68 of the decorative frame 35 is formed in a concave shape, and the lower side of the housing 30 is disposed thereon. The surface portion 68 of the decorative frame 35 is attached to the mounting portions 42 and 43 of the housing 30 with screws 41.

[0036] The surface portion 68 of the decorative frame 35 is provided with a light source window 69, which faces the light source 31 and through which the center of the lens 32 protrudes, and an inspection window 70, which faces the inspection portion 62. Furthermore, the surface portion 68 of the decorative frame 35 is provided with a water drainage hole 71, which drains water such as rainwater that has entered the inside of the decorative frame 35 to the outside.

[0037] As shown in Figure 4, the emergency light unit 13 is fixed to the fixture body 11 by inserting the housing 30 into the recess 23 of the fixture body 11 and abutting the upper surface of the storage section 44 against the lower surface of the top surface 19 of the fixture body 11, and then threading the screw 73 that passes through the top surface 19 into the housing 30.

[0038] 9 to 14 show the battery device 14. The battery device 14 is a waterproof battery device with a waterproof structure. The battery device 14 includes a plurality of batteries (unit cells) 80, a case 81 that houses the batteries 80, and a packing 82 that ensures that the case 81 is waterproof.

[0039] A rechargeable secondary battery such as a nickel-metal hydride battery or a lithium-ion battery is used as battery 80. Battery 80 is formed in a cylindrical shape, for example, the size of a third-generation dry cell battery, and has a positive electrode 84 on one axial end face and a negative electrode 85 on the other axial end face.

[0040] In this embodiment, seven batteries 80 are used, six of which are arranged at approximately equal intervals on the circumference, and one battery 80 is arranged in the center.

[0041] The seven batteries 80 are electrically connected in series, with the positive pole 84 and negative pole 85 of each adjacent battery 80 connected to each other facing in opposite directions, and the positive pole 84 of one battery 80 and the negative pole 85 of the other adjacent battery 80 connected to each other are connected by a conductive connecting plate 86. The connecting plate 86 is fixed to each pole of the batteries 80 by welding or the like.

[0042] Of the seven batteries 80 connected in series, the first battery 80a at one connection end has a negative terminal 85, which is the terminal to which the connection plate 86 is not connected, electrically connected to a first wiring 87 fixed by welding or the like, and the second battery 80b at the other connection end has a positive terminal 84, which is the terminal to which the connection plate 86 is not connected, electrically connected to a second wiring 88 fixed by welding or the like.

[0043] In this way, seven batteries 80 are connected to form a battery block 89. The battery block 89 is configured in a substantially hexagonal shape, with six batteries 80 arranged on the circumference at the vertices of the hexagon. The first battery 80a and the second battery 80b are arranged diagonally.

[0044] The case 81 also includes a case body 91 and a cover 92 that is detachably attached to the case body 91. The case body 91 and the cover 92 are each made of a resin material.

[0045] The case body 91 has a cylindrical portion 93 and an end surface portion 94, which is a bottom portion that closes one end surface of the cylindrical portion 93. An opening 95 is formed in the end surface of the cylindrical portion 93 opposite the end surface portion 94, and the battery block 89 is inserted into the cylindrical portion 93 through the opening 95.

[0046] The cylindrical portion 93 has six side surfaces 96 formed on the six batteries 80 arranged on the circumference of the approximately hexagonal battery block 89, each of which faces between adjacent batteries 80.

[0047] Of the side surface portions 96, the remaining (five) second side surface portions 96b, excluding one first side surface portion 96a, are formed in a substantially flat shape, and second corner portions 97b are formed between adjacent second side surface portions 96b. The second corner portions 97b are formed with curved surfaces that follow the outer peripheral shape of the batteries 80 to be housed, and position and hold the housed batteries 80 on the inner side of the second corner portions 97b.

[0048] The first side portion 96a is extended directly from the second side portion 96b without providing a second corner portion 97b between the first side portion 96a and the adjacent second side portion 96b, and a first corner portion 97a with a curved surface having a greater curvature than the second corner portion 97b is formed in the center.

[0049] The distance between the first side surface portion 96a and the opposing batteries 80 is wider than the distance between each second side surface portion 96b and the opposing batteries 80, and a wiring insertion area 98 through which the first wiring 87 is inserted is formed between the first side surface portion 96a and the opposing batteries 80.

[0050] The case body 91 is generally hexagonal in shape to accommodate a substantially hexagonal battery block 89 in which six batteries 80 are arranged circumferentially, but is formed with a substantially pentagonal cross-sectional shape having five corners 97 (one first corner 97a and four second corners 97b) to widen the gap between the first side surface portion 96a and the opposing batteries 80 and form a wiring insertion area 98. Corresponding to the cross-sectional shape of this case body 91, the end surface portion 94 is also formed with a substantially pentagonal shape.

[0051] The second side surface portion 96b adjacent to the first side surface portion 96a has a longer circumferential length than the second side surface portion 96b not adjacent to the first side surface portion 96a because the first side surface portion 96a is continuous with the second side surface portion 96b.

[0052] On the outer surfaces of the side surfaces 96 of the case body 91, there are protruding claws 99 that are attachment portions for attaching the cover 92.

[0053] A gas permeation hole 100 is provided in the end surface 94 of the case body 91 at a position at least partially facing the wire insertion region 98, and a gas permeation filter 101 is attached to cover this gas permeation hole 100. The gas permeation filter 101 is made of fluororesin or the like, and prevents the permeation of liquids such as rainwater, while allowing the permeation of gas generated by the battery 80.

[0054] The cover 92 includes a cover portion 102 that closes the opening of the case body 91 , and a cylindrical outer edge portion 103 that fits onto the outside of the case body 91 .

[0055] A cylindrical inner edge portion 104 that is inserted into the inside of the case body 91 protrudes from the inner surface of the cover portion 102, further inward than the outer edge portion 103. A battery retaining portion 105 protrudes from approximately the center of the inner surface of the cover portion 102. The inner edge portion (which also functions as a battery retaining portion) 104 and the battery retaining portion 105 protrude from the cover portion 102 further than the outer edge portion 103, and presses the end face of the battery 80 housed in the case body 91 against the end face portion 94 via the packing 82 to hold it in place.

[0056] The cover portion 102 , the outer edge portion 103 and the inner edge portion 104 are formed in a substantially pentagonal shape corresponding to the cross-sectional shape of the case body 91 .

[0057] Cover portion 102 has wiring insertion holes 106 adjacent to battery pressing portion 105. Hook portions 107, which are locking portions that lock onto claw portions 99 of case body 91 when cover 92 is combined with case body 91 via packing 82, are protruded from multiple locations on outer edge portion 103.

[0058] The packing 82 is integrally formed into a substantially pentagonal shape using, for example, rubber and is fitted inside the cover 92. The packing 82 is equipped with grooves 109, 110 into which the inner edge 104 and battery retaining portion 105 of the cover 92 are inserted, a contact portion 111 that is disposed between the outer surface of the inner edge 104 and the inner surface of the case body 91 and that contacts the inner surface of the case body 91, a pressing portion 112 that presses the end face of the battery 80 on the tip side of the inner edge 104 and the battery retaining portion 105, and a wire insertion portion 113 that penetrates and closes the wire insertion hole 106 of the cover 92. The wires 87, 88 are inserted through the wire insertion portion 113.

[0059] Next, the operation of the lighting device 10 will be described.

[0060] The emergency light unit 13 is fixed to the fixture body 11, and a battery storage space 47 is formed between the light source arrangement portion 46 and the fixing portion 55 protruding from one end side of the housing 30 and the top surface portion 19 of the fixture body 11.

[0061] The power supply connection wire drawn out from the wire insertion packing 50 of the emergency light unit 13 is electrically connected to the power supply drawn into the fixture body 11. The battery connection wire drawn out from the wire insertion packing 50 of the emergency light unit 13 is electrically connected to the wires 87, 88 drawn out from the wire insertion portion 113 of the battery device 14.

[0062] The battery device 14, electrically connected to the emergency light unit 13, is inserted into the battery accommodating space 47 and placed on the light source mounting portion 46 and the fixing portion 55 of the housing 30, and is accommodated in the battery accommodating space 47. As shown in Figures 4 and 5, the battery device 14 is oriented such that the cover 92 faces one end (the light source unit 12 side). The cover 92 rests on the fixing portion 55, and the case body 91 rests on the protrusion 45 and the light source mounting portion 46, and is arranged so as to slope downward toward the housing portion 44. This prevents the placed battery device 14 from shifting toward the light source unit 12 and popping out.

[0063] In the battery device 14, the second side surface portion 96b adjacent to the first side surface portion 96a is continuous with the first side surface portion 96a, and therefore has a longer circumferential planar length than the second side surface portion 96b not adjacent to the first side surface portion 96a. Therefore, when the second side surface portion 96b is placed on the protrusion 45 and the light source mounting portion 46 of the housing 30 with the second side surface portion 96b facing downward, the installation posture is stable.

[0064] The lighting unit 12 is disposed on one end side of the emergency light unit 13 relative to the fixture body 11, and a screw 28 (not shown) on one end of the lighting unit 12 is threadedly fixed to a fixing portion 24 of the fixture body 11. As shown in FIG. 4, the screw 28 on the other end side is threadedly fixed to a fixing portion 55 of the emergency light unit 13. The through portion 28a of the screw 28 on the other end side penetrates the fixing portion 55 and protrudes between the fixing portion 55 and the top surface 19, which is the inner surface of the fixture body 11 facing the fixing portion 55. The through portion 28a of the screw 28 prevents the light source mounting portion 46 on one end side of the housing 30 and the battery device 14 placed on the fixing portion 55 from shifting toward the light source unit 12 and jumping out. Therefore, the screw 28 functions to fix the light source unit 12 and prevent the battery device 14 from jumping out.

[0065] When the lighting device 10 is supplied with AC power from an external source, the AC power is supplied to the normal lighting unit of the light source unit 12 and to the power supply unit 33 of the emergency light unit 13. In the light source unit 12, the normal lighting unit converts the AC power to a predetermined lighting power and supplies it to the normal light source, which then lights up. In the emergency light unit 13, the charging circuit of the power supply unit 33 converts the AC power to a predetermined charging power and charges the battery 80 of the battery device 14.

[0066] Furthermore, when a power outage occurs and external AC power is no longer supplied to the lighting device 10, the light source unit 12 is turned off. The emergency light unit 13 operates on power discharged from the battery 80 of the battery device 14, converts the battery power from the battery device 14 into a predetermined lighting power and supplies it to the light source 31, which then lights up.

[0067] Furthermore, when inspecting the emergency light unit 13, an operator operates the remote control to send an inspection signal to the inspection unit 62 of the emergency light unit 13. When the inspection unit 62 receives the inspection signal, the power supply unit 33 of the emergency light unit 13 enters inspection mode, lights the light source 31 for a predetermined inspection time using power from the battery 80 of the battery device 14, and determines the state of the light source 31 and the life of the battery 80 of the battery device 14. The monitor lamp of the inspection unit 62 displays the inspection operation in progress and the inspection results. The operator can then visually check the inspection results by looking at the monitor lamp of the inspection unit 62 or by checking the inspection results received by the remote control. Note that the inspection operation of the emergency light unit 13 can also be performed by operating the inspection switch unit 63.

[0068] In this embodiment, the housing 30 of the emergency light unit 13 has the light source mounting section 46 for mounting the light source 31 at one end of the housing section 44 that houses the power supply unit 33, so there is no need to use a separate mounting part to mount the light source 31 in the housing 30, reducing the number of parts. This simplifies the structure of the emergency light unit 13 and improves assembly.

[0069] The light source arrangement section 46 protruding from one end side of the housing 30 forms a battery storage space 47 for accommodating the battery device 14 between it and the top surface section 19 of the fixture main body 11, so that the light source arrangement section 46 can fulfill two roles: arranging the light source 31 and forming the battery storage space 47.

[0070] A fixing portion 55 for attaching the light source unit 12 is provided on one end side of the light source arrangement portion 46 of the housing 30, making it easy to attach the light source unit 12 and to insert the battery device 14 into the battery accommodating space 47.

[0071] Since the through portion 28a of the screw 28 that attaches the light source unit 12 to the fixing portion 55 penetrates the fixing portion 55 and is positioned to protrude between the fixing portion 55 and the top surface 19, which is the inner surface of the fixture body 11 that faces the fixing portion 55, the battery device 14, which is arranged in the battery accommodating space 47 on the light source arrangement portion 46 at one end of the housing 30, can be prevented from shifting toward the light source unit 12 and popping out. Therefore, the screw 28 can serve the dual role of fixing the light source unit 12 and preventing the battery device 14 from popping out.

[0072] In addition, in the battery device 14, the distance between one first side surface portion 96a of the case body 91 of the case 81 and the opposing batteries 80 is wider than the distance between each of the other second side surface portions 96b and the opposing batteries 80, and a wiring insertion area 98 is formed between the first side surface portion 96a and the opposing batteries 80, so that the first wiring 87 connected to the first battery 80a at the back side of the case body 91 can be drawn out from the wiring insertion area 98 to the opening side of the case body 91.

[0073] The case body 91 of the case 81 accommodates six batteries 80 arranged circumferentially, but by forming the side shape to be approximately pentagonal rather than hexagonal, a wiring insertion area 98 can be formed between the batteries 80 at one first corner 97a.

[0074] The case body 91 of the case 81 is provided with a gas permeation hole 100 at a position at least partially facing the wire insertion region 98, so that gas generated by the battery 80 can be efficiently exhausted.

[0075] The lighting device 10 can also be applied to a fixture structure that does not include the light source unit 12 and includes only the emergency light unit 13.

[0076] Furthermore, the configuration of this embodiment is not limited to waterproof lighting devices, but can also be applied to lighting devices that do not have a waterproof structure.

[0077] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
