Description

Technical Field

[0001] The present disclosure relates to a lighting device.

Background Art

[0002] Conventionally, there has been a lighting device including a lighting fixture that is connected to an externally installed power supply device by an electric wire and is lit by receiving power supply from the power supply device (see, for example, Patent Document 1). The lighting device of Patent Document 1 has a plate-shaped bottom wall portion that is disposed between the lighting fixture and an attachment portion such as a ceiling and is fixed to the attachment portion, and an attachment plate portion for fixing the lighting fixture to the attachment portion. The lighting fixture is disposed to face the bottom wall portion at a position spaced apart from the bottom wall portion on the side opposite to the attachment portion side of the bottom wall portion. A terminal block electrically connected to the lighting fixture is disposed between the lighting fixture and the bottom wall portion. The terminal block has an electric wire insertion hole into which an electric wire is inserted. The lighting fixture draws an electric wire drawn out from the attachment portion through an electric wire hole provided in the bottom wall portion of the attachment plate portion into the internal space of the lighting device, bends the electric wire in the internal space and routes it in the internal space, and connects it to the terminal block, thereby being electrically connected to the power supply device.

[0003] In a configuration in which an electric wire is drawn into the internal space of the lighting device through an electric wire hole and is connected to an electric wire insertion hole in the internal space, the electric wire remains housed in the internal space even after connection. Therefore, in Patent Document 1, an installation space for the electric wire is formed inside the lighting device.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the lighting device of Patent Document 1, since an installation space for accommodating a part of the electric wire inside the lighting device is required, the lighting device has become larger, and reduction of the installation space for the electric wire has been demanded.

[0006] In order to meet the requirement of reducing the installation space for such an electric wire, it is conceivable to newly provide a terminal block holding part as a part for reducing the installation space for the electric wire in the lighting device, and by fixing the terminal block to the terminal block holding part, reduce the installation space for the electric wire. In this case, the installation position of the terminal block holding part may be restricted by the positions and structures of existing parts constituting the lighting device. For this reason, a configuration with a high degree of installation freedom is required for the terminal block holding part.

[0007] The present disclosure is for solving the above problems, and an object thereof is to provide a lighting device having a terminal block holding part that can reduce the installation space for an electric wire and has a high degree of installation freedom.

Means for Solving the Problems

[0008] The lighting device according to the present disclosure includes an instrument body having a bottom wall portion in which a wire passage hole through which an electric wire is passed is formed, a terminal block holding part having a plate-like movable part attached to the bottom wall portion so as to face the bottom wall portion and having a first movable part hole formed at a position facing the wire passage hole, and a terminal block including an input part to which an end portion of the electric wire passed through the wire passage hole and the first movable part hole is connected. The terminal block is fixed to an installation surface on the side opposite to the facing surface facing the bottom wall portion of the movable part so that the input part is exposed in the first movable part hole. The movable part is rotatably connected to the bottom wall portion of the instrument body so that the posture can be changed between a use posture in which the facing surface faces the bottom wall portion and a construction posture in which the facing surface is orthogonal or inclined to the surface direction of the bottom wall portion. The bottom wall portion has a protruding portion protruding toward the terminal block holding part side, and the terminal block holding part has an interference prevention hole for avoiding interference with the protruding portion.

Effects of the Invention

[0009] The lighting device according to the present disclosure is fixed to the installation surface of the movable part such that the input part of the terminal block is exposed through the first hole of the movable part in the use posture of the movable part. Therefore, in the lighting device, when the movable part is in the use posture during use, the input part of the terminal block is also exposed through the wire passing hole. Thus, when the movable part is in the use posture, the lighting device can hold the electric wire in a state where it is pushed into the back side of the wire passing hole, and it is possible to reduce the installation space of the electric wire in the lighting device. Further, the terminal block holding part has an interference prevention hole for avoiding interference with the protruding part of the bottom wall part of the instrument main body. Therefore, compared with a configuration without the interference prevention hole, the terminal block holding part can relax the restriction on the installation position of the terminal block holding part with respect to the instrument main body, and has a high degree of installation freedom.

[0013] In addition, the lighting device according to the present disclosure includes at least the second lighting fixture 4 described later, and for example, power is supplied from a battery disposed outside the lighting device to emit light from the second lighting fixture 4. The lighting device according to the present disclosure is, for example, an emergency light or an induction lamp. Note that the lighting device according to the present disclosure is not limited to emergency lights and induction lamps.

[0014] Embodiment First, the overall configuration of the lighting device 1 according to the present embodiment will be described with reference to FIGS. 1 to 6.

[0015] FIG. 1 is a perspective view of the lighting device 1 according to the embodiment as viewed from below. FIG. 2 is an exploded perspective view of the lighting device 1 according to the embodiment. FIG. 3 is a perspective view of the lighting device 1 according to the embodiment in which the terminal block holding portion 50 is separated from the fixture body 2. FIG. 4 is a bottom view of the fixture body 2 of the lighting device 1 according to the embodiment in a state where the first lighting fixture 3 and the second lighting fixture 4 are removed from the fixture body 2. FIG. 5 is a bottom view of the fixture body 2 of the lighting device 1 according to the embodiment. FIG. 6 is an explanatory view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment, and is a perspective view of the state during use of the terminal block holding portion 50 as viewed from below.

[0016] The lighting device 1 includes at least one lighting fixture that emits light. Hereinafter, the lighting fixture included in the lighting device 1 is referred to as the second lighting fixture 4. In addition, the lighting device 1 includes a first lighting fixture 3 in addition to the second lighting fixture 4. Further, the lighting device 1 includes a fixture body 2 to which the first lighting fixture 3 and the second lighting fixture 4 are attached. That is, the lighting device 1 includes the first lighting fixture 3, the second lighting fixture 4, and the fixture body 2 to which the first lighting fixture 3 and the second lighting fixture 4 are attached. As shown in FIG. 2, the lighting device 1 is attached to an attachment portion W such as a ceiling or a wall.

[0017] The first lighting fixture 3 emits light with power supplied from an external power source such as a commercial power supply. The first lighting fixture 3 is supplied with power from an external power source via the electric wire 7a.

[0018] The second lighting fixture 4 emits light using electric power supplied from a separate power source different from an external power source. The separate power source is, for example, a battery disposed outside the lighting device 1 as described above. Note that the separate power source is not limited to a battery disposed outside the lighting device 1, and may be a battery disposed inside the lighting device 1. The second lighting fixture 4 is supplied with electric power from the separate power source via the electric wire 110. Specifically, for example, the second lighting fixture 4 emits light using the electric power supplied from the separate power source when the electric power supplied from the external power source to the first lighting fixture 3 stops. Note that the lighting device 1 may have a configuration having only the second lighting fixture 4 without having a lighting fixture corresponding to the first lighting fixture 3.

[0019] (Apparatus main body 2) The apparatus main body 2 is attached to an attachment portion W such as a ceiling or a wall, and is a housing to which the first lighting fixture 3 and the second lighting fixture 4 are attached. As shown in FIG. 2, the apparatus main body 2 has two attachment bolts 10 fixed to the attachment portion W with a space therebetween passed through two bolt through-holes 12c described later, and is fixed to the attachment portion W by tightening nuts 10a (see FIG. 11) to the attachment bolts 10. Note that the number of attachment bolts 10 used for attaching the apparatus main body 2 to the attachment portion W is not limited to two, and may be three or more.

[0020] The apparatus main body 2 includes a main body portion 11, a pair of apparatus inclined portions 15, and a pair of end portions 17.

[0021] The main body portion 11 is formed in a long shape, and a cross section cut by a plane orthogonal to the longitudinal direction X is substantially inverted U-shaped. The main body portion 11 includes a bottom wall portion 12 and a pair of side wall portions 13.

[0022] The bottom wall portion 12 is configured in a long plate shape. The bottom wall portion 12 is disposed along the attachment portion W such as a ceiling, and serves as an attachment portion of the lighting device 1 to the attachment portion W. Note that the bottom wall portion 12 is also referred to as a top surface portion. The bottom wall portion 12 is formed in a long shape along the longitudinal direction X, and is formed in a flat plate shape extending in the longitudinal direction X and the short direction Y.

[0023] The pair of side wall portions 13 are formed to project from both ends of the bottom wall portion 12 in the lateral direction Y so as to face each other. The pair of side wall portions 13 extend downward in the Z2 direction from the bottom wall portion 12 and also extend in the longitudinal direction X. Here, the main body portion 11 is formed by bending a metal plate material, that is, sheet metal, by pressing or rolling. Note that the main body portion 11 may be formed by a process such as extrusion molding or three-dimensional modeling.

[0024] Each of the pair of instrument inclined portions 15 is an inclined wall that projects away from the main body portion 11 in the lateral directions Y1 and Y2 of the main body portion 11 from the lower ends of the pair of side wall portions 13 of the main body portion 11. The pair of instrument inclined portions 15 are inclined so as to approach the mounted portion W as they move away from the main body portion 11.

[0025] The pair of end portions 17 are formed in the shape of an inverted trapezoidal plate. The pair of end portions 17 close both longitudinal ends of the integral body of the main body portion 11 and the pair of instrument inclined portions 15.

[0026] The instrument main body 2 forms a concave lighting fixture housing portion 18 by closing both longitudinal ends of the integral body of the main body portion 11 and the pair of instrument inclined portions 15 with the pair of end portions 17. The upper portion of the lighting fixture housing portion 18 is constituted by the plate-shaped bottom wall portion 12 of the main body portion 11, and the side portions are constituted by the pair of side wall portions 13 and the pair of end portions 17 of the main body portion 11. The lighting fixture housing portion 18 has an open configuration at the lower side and has an opening 19 on the lower side facing the bottom wall portion 12. The first lighting fixture 3 is attached to the instrument main body 2 from the opening 19 of the instrument main body 2, and a part of it is housed in the lighting fixture housing portion 18. The first lighting fixture 3 is attached to the main body portion 11 by attachment springs 20 provided at both longitudinal ends of the bottom wall portion 12.

[0027] As shown in FIGS. 4 and 5, on the bottom wall portion 12, there are formed a first wire through-hole 12a for introducing an electric wire 7a electrically connected to the first lighting fixture 3 from the outside, and a second wire through-hole 12b for introducing an electric wire 110 electrically connected to the second lighting fixture 4 from the outside. The first wire through-hole 12a is formed at the center of the bottom wall portion 12 in each of the longitudinal direction X and the lateral direction Y. The first wire through-hole 12a is circular in the illustrated example, but is not limited to a circular shape and may be other shapes such as a rectangular shape.

[0028] The second wire through-hole 12b is formed at a position closer to the end side in the longitudinal direction X than the first wire through-hole 12a. The second wire through-hole 12b is formed at the center of the bottom wall portion 12 in the lateral direction Y. The second wire through-hole 12b is formed in a circular shape with a diameter larger than that of the first wire through-hole 12a. Note that the second wire through-hole 12b is not limited to a circular shape and may be other shapes such as a rectangular shape.

[0029] A first terminal block 7 is attached to the bottom wall portion 12. The electric wire 7a drawn into the lighting fixture housing portion 18 through the first wire through-hole 12a is electrically connected to the first terminal block 7. Note that the illustration of the electric wire 7a is omitted in FIGS. 3 and 4. Also, a wiring 7b is drawn out from the first terminal block 7, and the connector 7b1 at the tip of the wiring 7b is electrically connected to the first lighting fixture 3. Thereby, power is supplied from an external power source to the first lighting fixture 3 via the electric wire 7a, the first terminal block 7, the wiring 7b, and the connector 7b1.

[0030] Also, a terminal block holding portion 50 to which a second terminal block 80 is fixed is attached to the bottom wall portion 12. The terminal block holding portion 50 is attached to the bottom wall portion 12 so as to cover the formation portions of the second wire through-hole 12b and a bolt through-hole 12c (described later) from the Z2 side. The electric wire 110 drawn into the lighting fixture housing portion 18 through the second wire through-hole 12b is electrically connected to the second terminal block 80. Also, as shown in FIG. 2, a wiring 42 drawn out from the second lighting fixture 4 is electrically connected to the second terminal block 80. Thereby, power is supplied from a separate power source to the second lighting fixture 4 via the electric wire 110, the second terminal block 80, and the wiring 42.

[0031] As shown in FIG. 2, the terminal block holding portion 50 is attached to the bottom wall portion 12 adjacent to the first terminal block 7. Since the first terminal block 7 and the second terminal block 80 are attached to the bottom wall portion 12 adjacent to each other, compared with a configuration in which the first terminal block 7 and the second terminal block 80 are attached to the bottom wall portion 12 separately, wiring work can be easily carried out collectively, and workability can be improved. Here, "adjacent" includes both being in contact with each other and adjacent to each other, and being adjacent to each other without being in contact with each other.

[0032] Also, as shown in FIGS. 4 and 5 and the like, bolt through holes 12c are formed in the bottom wall portion 12. The bolt through holes 12c are holes through which mounting bolts 10 for attaching the appliance main body 2 to the attachment portion W as an external portion are passed, which are bolts suspended from the attachment portion W as an external portion. Four bolt through holes 12c are formed in the bottom wall portion 12 at intervals in the longitudinal direction X. The bolt through holes 12c have two sets, namely, two bolt through holes 12c formed at a distance P1 in the X direction as shown in FIG. 4 and two bolt through holes 12c formed at a distance P2 in the X direction.

[0033] Here, the pitches of the fixing intervals of the plurality of mounting bolts 10 fixed to the attachment portion W are different depending on the property. Since the appliance main body 2 has two sets of bolt through holes 12c with different pitches as described above here, it can correspond to properties with pitch P1 and property P2, and can be installed on various properties.

[0034] The appliance main body 2 is attached to the attachment portion W by passing the mounting bolts 10 through the bolt through holes 12c in the bottom wall portion 12 and the interference prevention holes 50b (described later) of the terminal block holding portion 50 and tightening nuts 10a (see FIG. 11).

[0035] The first wire through-hole 12a, the second wire through-hole 12b, and the bolt through-hole 12c provided in the bottom wall portion 12 are arranged at the central portion in the short-side direction Y of the bottom wall portion 12 as shown in FIG. 5. Specifically, the first wire through-hole 12a, the second wire through-hole 12b, and the bolt through-hole 12c are arranged such that their centers are located on the center line A, and in particular, on the center line A in the short-side direction Y of the appliance main body 2. When installing the appliance main body 2 on the mounting portion W, a hole is drilled at a position on the mounting portion W that faces the second wire through-hole 12b for passing the wire 110. Since the second wire through-hole 12b is located at the central portion in the short-side direction Y of the appliance main body 2, it is easy to indicate approximately where to drill the hole with respect to the mounting portion W, and the hole drilling during construction can be facilitated.

[0036] The appliance main body 2 has an appliance through-hole 16 that penetrates in the vertical direction Z and opens in the short-side direction Y in one of the pair of appliance inclined portions 15. The appliance through-hole 16 is a portion for accommodating the second lighting fixture 4. The second lighting fixture 4 is disposed in the appliance through-hole 16 and fixed to the bottom wall portion 12 of the main body portion 11. Note that the appliance main body 2 according to the present embodiment is a V-shaped type of lighting fixture. However, the present invention is not limited to this, and the appliance main body 2 may be a lighting fixture such as a hat type, a one-sided reflector hat type, or a trough type.

[0037] (The first lighting fixture 3) The first lighting fixture 3 is, for example, a commonly used lighting fixture. In other words, the first lighting fixture 3 is a commonly used lighting fixture that lights up in a normal state. The normal state refers to a state in which power is supplied to the lighting device 1 from an external power source such as a commercial power supply. On the other hand, the abnormal state refers to a state in which power is not supplied to the lighting device 1 from the external power source due to some cause such as a power outage. When the lighting device 1 is in a lit state in the normal state, light is emitted from the first lighting fixture 3 toward the irradiated area such as the interior of the room.

[0038] The first lighting fixture 3 is also referred to as a first lamp, a first light source unit, a normal lighting fixture, a normal light source unit, or the like. The first lighting fixture 3 is formed in a long shape in the longitudinal direction X and is attached to and used with the fixture body 2. The first lighting fixture 3 has an outer shell portion 31 and the like. The outer shell portion 31 is a member that constitutes the outer shell of the first lighting fixture 3. The outer shell portion 31 is made of at least a light-transmitting material that transmits visible light. The outer shell portion 31 is, for example, a light-transmitting cover formed using a resin material such as glass, polycarbonate, or acrylic. Note that a portion of the outer shell portion 31 that is not exposed from the lighting fixture housing portion 18 may be configured of a material having reflectivity, light-shielding property, or the like.

[0039] A light source portion (not shown) is housed inside the outer shell portion 31. The light source portion includes a light-emitting element such as a light-emitting diode or an LED element. That is, when the lighting device 1 is in the lit state in the normal state, light is emitted from the light-emitting element.

[0040] The first lighting fixture 3 includes a mounting fitting (not shown), and the mounting fitting is hooked on the mounting spring 20 of the main body portion 11 and held by the main body portion 11.

[0041] (Second lighting fixture 4) The second lighting fixture 4 is, for example, an emergency lighting fixture. In other words, the second lighting fixture 4 is an emergency lighting fixture that lights up in an emergency state. The emergency state means, as described above, a state in which power is not supplied to the lighting device 1 from an external power source due to some cause such as a power outage. When the lighting device 1 is in the lit state in the emergency state, light is emitted from the second lighting fixture 4 toward the irradiated area.

[0042] The second lighting fixture 4 is attached to the fixture body 2 outside the first lighting fixture 3. The second lighting fixture 4 is also referred to as a second lamp, a second light source unit, an emergency lighting fixture, an emergency light source unit, or the like. The second lighting fixture 4 is disposed in the fixture through-hole 16.

[0043] The second lighting fixture 4 is formed in an elongated shape in the longitudinal direction X and is attached to the fixture main body 2 along the longitudinal direction X. The second lighting fixture 4 is arranged side by side with the first lighting fixture 3 in the short-side direction Y. The second lighting fixture 4 is arranged such that the longitudinal direction of the first lighting fixture 3 and the longitudinal direction of the second lighting fixture 4 are parallel in a bottom view seen from the irradiated area side. The light-emitting portion of the second lighting fixture 4 is substantially at the center of the second lighting fixture 4 in the longitudinal direction X.

[0044] The second lighting fixture 4 includes a housing 40, a light source unit 41 housed in the housing 40, and a wiring 42 electrically connected to the light source unit 41 and extended outside the housing 40. The housing 40 is formed in a box shape with the X direction as the longitudinal direction. The housing 40 has a pair of side surfaces facing each other in the Z direction, and a light passage hole 43 penetrating in the Z direction is formed in the side surface opposite to the side fixed to the bottom wall portion 12.

[0045] The light source unit 41 is a portion provided with a light-emitting element such as an LED, for example. The light source unit 41 is fixed in the housing 40 such that the light-emitting element is exposed from the light passage hole 43. Thereby, the second lighting fixture 4 is configured such that the light emitted from the light source unit 41 passes through the light passage hole 43 and is irradiated outside the housing 40.

[0046] (Terminal block holding portion 50) FIG. 7 is a perspective view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment. FIG. 8 is an exploded perspective view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment. FIG. 9 is an exploded perspective view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment as seen from a direction different from FIG. 8. FIG. 10 is a perspective view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment in a construction posture. FIG. 11 is an explanatory view of the terminal block holding portion 50 of the lighting device 1 according to the embodiment, and is a perspective view of the state during construction of the terminal block holding portion 50 observed from below.

[0047] The terminal block holding part 50 has a second terminal block 80 to which the electric wire 110 is connected. The terminal block holding part 50 is a component for reducing the installation space of the electric wire 110 as described below, and is a component having versatility applicable to lighting devices with various configurations. Here, the electric wire 110 is, for example, a fire-resistant cable, which is a conductor covered with a fire-resistant coating material. The electric wire 110 is hard and difficult to bend, and has the property of being difficult to reduce the bending radius. The terminal block holding part 50 also has a configuration capable of improving the workability related to the connection of such a difficult-to-bend electric wire 110 to the second terminal block 80.

[0048] The terminal block holding part 50 includes a long plate-shaped base part 60 attached to the bottom wall part 12 of the appliance main body 2, a long plate-shaped movable part 70 rotatably connected to the base part 60 at one end in the longitudinal direction X, a second terminal block 80 fixed to the movable part 70, and a terminal block cover 90 that covers the second terminal block 80 and is fixed to the movable part 70. Hereinafter, the X1 direction is the direction on one end side in the longitudinal direction X where the movable part 70 is connected to the base part 60, and the X2 direction is the direction on the other end side in the longitudinal direction X. These directions are defined for convenience in explaining the embodiment, and do not limit the lighting device according to the present disclosure.

[0049] The base part 60 is configured in a long plate shape with the X direction as the longitudinal direction and the Y direction as the short side direction. The base part 60 includes a long plate-shaped base main part 61, a pair of rotation fixing pieces 62 extending in the Z2 direction from both end edges in the Y direction of the base main part 61, and a holding fixing piece 63 extending in the Z2 direction from the edge of the end in the X2 direction of the base main part 61.

[0050] The base main part 61 is a part attached to the bottom wall part 12. The base main part 61 has a base first hole 61a and a base second hole 61b. The base first hole 61a is a hole for passing the electric wire 110 (see FIG. 3) drawn out from the attached part W in the Z2 direction from the Z1 side. The base second hole 61b is a hole for passing the mounting bolt 10 (see FIG. 2) for suspending and fixing the appliance main body 2 to the attached part W in the Z2 direction from the Z1 side. The base first hole 61a and the base second hole 61b are circular in the illustrated example, but are not limited to circular, and may be other shapes such as rectangular.

[0051] As shown in FIG. 9 and the like, the base main part 61 further has through holes 61c for fixing the base 60 to the bottom wall part 12 of the instrument main body 2. The through holes 61c are formed at two positions spaced apart in the Y direction at the end on the X1 side of the base main part 61 and at two positions spaced apart in the Y direction at the end on the X2 side of the base main part 61.

[0052] The pair of rotation fixing pieces 62 are parts for rotatably fixing the movable part 70. Each of the pair of rotation fixing pieces 62 has a first shaft hole 62a penetrating in the Y direction. The first shaft hole 62a is a part into which a shaft part 721 described later is inserted. The first shaft holes 62a of each of the pair of rotation fixing pieces 62 are formed coaxially extending in the Y direction.

[0053] The holding and fixing piece 63 is a part for fixing the movable part 70 in the later-described use posture shown in FIG. 7. The holding and fixing piece 63 is provided at the end in the Y1 direction at the edge of the end in the X2 direction of the base main part 61. The holding and fixing piece 63 is formed in a plate shape extending in the X2 direction after extending in the Z2 direction from the base main part 61, and a through hole 63a is formed at the tip.

[0054] The movable part 70 is a part for rotatably supporting the second terminal block 80 with respect to the base 60. The movable part 70 is configured in a long plate shape. The movable part 70 is disposed on the Z2 side with respect to the base 60. The movable part 70 is rotatably connected to the base 60 in a use posture facing the base 60 as shown in FIGS. 6 and 7 and in a construction posture standing upright with respect to the base 60 as shown in FIGS. 10 to 11.

[0055] The usage posture is the posture of the lighting device 1 in a state where the assembly is completed and ready for use, and is a posture in which the opposing surface 70a described later faces parallel to the bottom wall portion 12. The construction posture is the posture when connecting the electric wire 110 to the second terminal block 80 during the assembly process of the lighting device 1. In FIGS. 10 to 11, as the construction posture, a posture in which the movable part 70 stands upright with respect to the base part 60, in other words, a posture in which the opposing surface 70a of the movable part 70 with respect to the base part 60 is orthogonal to the surface direction (XY plane direction) of the base part 60 is shown, but it is not limited to this posture. The construction posture may be a posture in which the opposing surface 70a of the movable part 70 with respect to the base part 60 is inclined with respect to the surface direction of the base part 60.

[0056] Hereinafter, the structure of the movable part 70 will be described using the directions when the movable part 70 is in the usage posture of FIG. 7 and the directions shown in the exploded perspective views of FIGS. 8 and 9.

[0057] The movable part 70 has a long plate-shaped movable part main body 71, a pair of fixed pieces 72 extending in the Z2 direction from both end edges of the movable part main body 71 in the Y direction, and a holding and fixing piece 73 extending in the Z2 direction from the edge of the end of the movable part main body 71 in the X2 direction.

[0058] The movable part main body 71 has an opposing surface 70a facing the base part 60 and an installation surface 70b on the side opposite to the opposing surface 70a. The movable part main body 71 has a movable part first hole 71a and a movable part second hole 71b.

[0059] The movable part first hole 71a is formed at a position facing the base part first hole 61a of the base part 60 in the usage posture. The movable part first hole 71a is provided to expose the input side insertion hole 82a1 of the second terminal block 80, which will be described later, fixed to the installation surface 70b of the movable part main body 71 to the opposing surface 70a side. The movable part first hole 71a is formed in a rectangular shape according to the outer shape of the second terminal block 80. Note that the movable part first hole 71a is not limited to a rectangle, and may have other shapes as long as the input side insertion hole 82a1 can be exposed to the opposing surface 70a side. The movable part first hole 71a, together with the base part first hole 61a of the base part 60, constitutes an electric wire hole 50a through which the electric wire 110 passes in the terminal block holding part 50.

[0060] The movable part second hole 71b is formed at a position facing the base second hole 61b of the base 60 in the use state. The movable part second hole 71b is a hole for passing the mounting bolt 10 for suspending and fixing the instrument body 2 to the mounted part W in the Z2 direction. The movable part second hole 71b is circular in the illustrated example, but is not limited to a circular shape and may have other shapes such as a rectangular shape. The movable part second hole 71b and the base second hole 61b of the base 60 together constitute an interference prevention hole 50b through which the mounting bolt 10 passes in the terminal block holding part 50. Note that an electric wire 7a may be passed through the interference prevention hole 50b together with the mounting bolt 10.

[0061] Further, the main part 71 of the movable part has cover fixing holes 74 (see FIG. 9). The cover fixing holes 74 are holes for fixing the terminal block cover 90 to the main part 71 of the movable part. The cover fixing holes 74 are formed at two positions on both sides in the Y direction of the first hole 71a of the movable part.

[0062] The pair of fixed pieces 72 are provided over the entire X direction of the main part 71 of the movable part at both end edges in the Y direction of the main part 71 of the movable part. As shown in FIG. 7 and the like, the pair of fixed pieces 72 are arranged inside the pair of rotation fixing pieces 62 of the base 60. The pair of fixed pieces 72 have a pair of second shaft holes 72a penetrating in the Y direction at positions facing the pair of first shaft holes 62a of the pair of rotation fixing pieces 62. A pair of columnar shaft portions 721 are inserted into the pair of second shaft holes 72a and the pair of first shaft holes 62a from the outside of the pair of rotation fixing pieces 62. The movable part 70 is rotatably connected to the base 60 at the end on the X1 side by the pair of shaft portions 721 serving as a rotation connecting part.

[0063] The holding and fixing piece 73 is provided at the end in the Y1 direction at the edge of the end in the X2 direction of the main part 71 of the movable part. The holding and fixing piece 73 is formed in a plate shape that extends in the X2 direction after extending in the Z2 direction from the main part 71 of the movable part, and a through hole 73a is formed at the tip. The through hole 73a is formed at a position facing the through hole 63a formed in the holding and fixing piece 63 of the base 60 in the use posture. A fixture 731 such as a screw is passed through the through hole 73a and the through hole 63a in the use posture. The movable part 70 is fixed to the base 60 by passing the fixture 731 through the through hole 73a and the through hole 63a and tightening a nut (not shown), and the use posture is maintained. In the use posture, the main part 71 of the movable part faces the main part 61 of the base in a parallel state.

[0064] The second terminal block 80 has a flat input part 82 and a box-shaped output part 83 with an opening on the Z1 side. The second terminal block 80 is formed in a rectangular parallelepiped shape with the opening of the output part 83 blocked by the input part 82. The input part 82 is a part to which the electric wire 110 is connected, and one surface facing the Z1 side is the input surface 82a. The output part 83 is a part to which the wiring 42 (see FIG. 2) is connected, and the surface facing the X1 side is the output surface 83a.

[0065] The input part 82 has a plurality of input-side insertion holes 82a1 into which the electric wire 110 is inserted, and the input-side insertion holes 82a1 open on the input surface 82a. The input-side insertion holes 82a1 are formed to extend in a direction perpendicular to the input surface 82a. The output part 83 has a plurality of output-side insertion holes 83a1 into which the wiring 42 is inserted, and the output-side insertion holes 83a1 open on the output surface 83a. The output-side insertion holes 83a1 are formed to extend in a direction perpendicular to the output surface 83a. The second terminal block 80 electrically connects the electric wire 110 and the wiring 42 by inserting the electric wire 110 into the input-side insertion holes 82a1 and inserting the wiring 42 into the output-side insertion holes 83a1.

[0066] The second terminal block 80 is attached to the installation surface 70b of the main part 71 of the movable part. The second terminal block 80 is attached to the installation surface 70b at a position covering the first hole 71a of the movable part from the side of the installation surface 70b. By attaching the second terminal block 80 to the installation surface 70b at a position covering the first hole 71a of the movable part from the side of the installation surface 70b, the input surface 82a of the input part 82 is exposed to the side of the opposing surface 70a through the first hole 71a of the movable part.

[0067] Also, the second terminal block 80 has screw holes 84. The screw holes 84 are holes for fixing the second terminal block 80 to the terminal block cover 90.

[0068] The terminal block cover 90 is a plate-shaped cover for covering the second terminal block 80 and fixing it to the movable part 70. The terminal block cover 90 has a rectangular first surface part 91, a pair of second surface parts 92 extending in the Z1 direction from both end edges in the Y direction of the first surface part 91, and a pair of third surface parts 93 extending outward from the leading edge edges of the pair of second surface parts 92.

[0069] The first surface part 91 has first cover fixing holes 91a. The first cover fixing holes 91a are holes for fixing the terminal block cover 90 to the second terminal block 80. The terminal block cover 90 is fixed to the second terminal block 80 by a fixture 911 inserted into the first cover fixing holes 91a being screwed into the screw holes 84 of the second terminal block 80.

[0070] The third surface part 93 has second cover fixing holes 93a. The second cover fixing holes 93a are holes for fixing the terminal block cover 90 to the movable part 70. The terminal block cover 90 is fixed to the movable part 70 by a fixture 711 such as a screw being passed through the cover fixing hole 74 of the movable part 70 and the second cover fixing hole 93a of the terminal block cover 90 and a nut (not shown) being tightened.

[0071] In this way, the second terminal block 80 is fixed to the terminal block cover 90 by the fixture 911, and the terminal block cover 90 is fixed to the movable part 70 by the fixture 711, so that it is fixed to the movable part 70.

[0072] In the illustrated example, the terminal block holding portion 50 is shown as having a base portion 60, but the base portion 60 can be omitted. That is, the terminal block holding portion 50 may be configured such that the movable portion 70 is directly and rotatably connected to the bottom wall portion 12 of the appliance main body 2. In this configuration, the movable portion 70 is directly overlapped with the bottom wall portion 12 in the use posture and is rotatably connected.

[0073] The terminal block holding portion 50 configured as described above is arranged with the base portion 60 in contact with the bottom wall portion 12 of the appliance main body 2 as shown in FIG. 11 and the like. The terminal block holding portion 50 is attached to the bottom wall portion 12 of the appliance main body 2 by passing a fixture 611 passed through the bottom wall portion 12 from the Z1 side to the Z2 side through a through hole 61c of the base portion 60 and tightening a nut (not shown). In a state where the terminal block holding portion 50 is attached to the bottom wall portion 12, the second wire through hole 12b of the bottom wall portion 12 communicates with the wire hole 50a, and the bolt through hole 12c of the bottom wall portion 12 communicates with the interference prevention hole 50b. And the terminal block holding portion 50 is rotatable with respect to the base portion 60 in the construction posture shown in FIGS. 10 to 11 and the use posture shown in FIG. 7 as described above for the movable portion 70.

[0074] Next, the operation of the above-described configuration will be described for the construction time and the use time, respectively.

[0075] FIG. 12 is a schematic diagram for explaining the operation of the lighting device 1 according to the embodiment. FIG. 12(a) is a view showing a state where the movable portion 70 is in the construction posture, and FIG. 12(b) is a view showing a state where the movable portion 70 is in the use posture. In FIG. 12, illustration of the base portion 60 of the terminal block holding portion 50 and portions unnecessary for explaining the operation is omitted. FIG. 13 is a schematic diagram of the lighting device according to the comparative example during use.

[0076] (During construction) During construction, when connecting the electric wire 110 to the second terminal block 80, the movable part 70 is in the construction position as shown in Fig. 12(a). Note that the connection of the electric wire 110 to the second terminal block 80 is performed after the appliance body 2 is installed on the mounting part W using the mounting bolts 10. When the movable part 70 is in the construction position, a construction space is secured in front of the input part 82 of the second terminal block 80 in the internal space S1 of the appliance body 2. Then, the constructor connects the electric wire 110 drawn out from the second wire passage hole 12b in the bottom wall part 12 of the appliance body 2 to the input part 82 of the second terminal block 80. Although the electric wire 110 has the property of being difficult to bend tightly as described above, in the state of Fig. 12(a), since a large construction space is secured, the electric wire 110 can be inserted into the input side insertion hole 82a1 of the input part 82 with a large bending radius. Therefore, the constructor can connect the electric wire 110 to the input part 82 of the second terminal block 80 without forcibly bending it. Thus, the lighting device 1 can improve the workability related to the connection of the electric wire 110 to the second terminal block 80.

[0077] Also, the movable part 70 is in the shape of a long plate, and has a first movable part hole 71a through which the electric wire 110 passes at the other end opposite to the end provided with the rotation connection part in the longitudinal direction (the vertical direction in Fig. 12(a)). For this reason, compared with the configuration in which the lighting device 1 has the first movable part hole 71a at one end in the longitudinal direction of the movable part 70, that is, near the rotation connection part, the distance between the second wire passage hole 12b and the first movable part hole 71a when in the construction position can be increased. Thereby, the lighting device 1 can secure a construction space during construction and enables the electric wire 110 to be inserted into the input side insertion hole 82a1 of the second terminal block 80 with a large bending radius. Therefore, the constructor can connect the electric wire 110 to the input part 82 of the second terminal block 80 without forcibly bending it. Thus, the lighting device 1 can improve the workability related to the connection of the electric wire 110 to the second terminal block 80.

[0078] Further, the second terminal block 80 is provided at the other end of the movable part 70 in the longitudinal direction, which is opposite to the rotation connection part. Since the heavy second terminal block 80 is provided at the other end of the movable part 70 in the longitudinal direction, which is opposite to the rotation connection part, the movable part 70 is easier to rotate than the configuration in which the second terminal block 80 is provided at one end.

[0079] (During use) During use, as shown in Fig. 12(b), the movable part 70 is in the use posture. The second terminal block 80 is fixed to the movable part 70 such that the input surface 82a of the input part 82 is exposed through the first hole 71a of the movable part. Therefore, when the movable part 70 is in the use posture during use, the input surface 82a of the input part 82 is further exposed to the second wire through hole 12b.

[0080] Here, in the construction posture shown in Fig. 12(a), a part of the wire 110 is located in the internal space S1 of the appliance body 2. When the movable part 70 is changed to the use posture from this state, the wire part located in the internal space S1 of the appliance body 2 is pushed into the back side of the second wire through hole 12b. Therefore, the lighting device 1 does not need to route the wire 110 in the internal space S1 of the appliance body 2. For this reason, since the lighting device 1 does not need to route the wire 110 in the internal space S1, specifically, in the luminaire housing part 18, the installation space of the wire 110 can be reduced.

[0081] In the lighting device of the comparative example shown in Fig. 13, in the use state, the wire 1100 passed through the wire through hole 120a of the bottom wall part 120 is routed in the X direction in the internal space S0 of the appliance body 200 and inserted into the terminal block 800. The insertion direction of the wire 1100 into the terminal block 800 is the X direction, which intersects the Z direction, which is the insertion direction of the wire 1100 into the wire through hole 120a. For this reason, the wire 1100 inserted into the internal space S0 from the wire through hole 120a is bent in the internal space S0, and after the direction is changed from the Z direction to the X direction, it is inserted into the terminal block 800. Therefore, in the lighting device of the comparative example, in the use state, it is necessary to secure a space for bending the wire 1100 in the internal space S0.

[0082] Here, since the electric wire 1100 has a property of being difficult to bend rigidly, in order to direct the tip of the electric wire 1100 passed through the wire passage hole 120a in the Z direction in the X direction, it is necessary to crawl while bending the electric wire 1100 within the internal space S0. For this reason, in the lighting device of the comparative example, it is necessary to ensure a relatively long X-direction distance L between the wire passage hole 120a and the terminal block 800. Further, in the lighting device of the comparative example, in order to crawl the difficult-to-bend electric wire 1100 within the internal space S0, a force for pressing the electric wire 1100 toward the bottom wall portion 120 as shown by the arrow in FIG. 13 is required.

[0083] On the other hand, in the lighting device 1, during use, as shown in FIG. 12(b), when the movable part 70 is in the use posture, the insertion direction of the electric wire 110 with respect to the input-side insertion hole 82a1 of the second terminal block 80 becomes the same Z direction as the insertion direction of the electric wire 110 with respect to the second wire passage hole 12b. For this reason, in the use state, the electric wire 110 passed through the second wire passage hole 12b is inserted into the input-side insertion hole 82a1 of the second terminal block 80 without being bent. Therefore, the lighting device 1 does not need to secure a space for bending the electric wire 110 in the internal space S1 of the appliance body 2, so that the installation space of the electric wire 110 can be reduced. Further, since the lighting device 1 does not need to crawl the electric wire 110 within the internal space S1, a force for pressing the electric wire 110 toward the bottom wall portion 12 is not required, and the workability can be improved.

[0084] (Degree of freedom in installing the terminal block holding portion 50) As described above, the lighting device 1 can reduce the installation space of the electric wire 110 by having the terminal block holding portion 50. Considering newly installing the terminal block holding portion 50 on the existing appliance body 2, the terminal block holding portion 50 needs to have a configuration that does not interfere with the existing parts. The terminal block holding portion 50 has interference prevention holes 50b, and the mounting bolts 10 as existing parts can pass through the interference prevention holes 50b, thereby avoiding interference with the existing parts.

[0085] If the terminal block holding portion 50 does not have the interference prevention hole 50b, the terminal block holding portion 50 must be installed on the appliance body 2 avoiding the position of the mounting bolt 10, and the installation position is restricted. On the other hand, since the terminal block holding portion 50 has the interference prevention hole 50b, interference with existing parts can be avoided, so the degree of freedom of the installation position with respect to the appliance body 2 can be increased.

[0086] The size of the interference prevention hole 50b is set in consideration of the diameter and length of the mounting bolt 10. If the size of the interference prevention hole 50b is too small with respect to the length of the mounting bolt 10, when the movable part 70 is rotated from the construction posture to the use posture, the mounting bolt 10 may interfere with the movable part second hole 71b which is a part of the interference prevention hole 50b and rotation may become impossible. Therefore, the size of the interference prevention hole 50b is set in consideration of the rotation of the movable part 70.

[0087] Here, although the existing part to be prevented from interfering by the interference prevention hole 50b is assumed to be the mounting bolt 10, it is not limited to the mounting bolt 10. The existing part to be prevented from interfering may be a projection provided on the appliance body 2, such as an emboss protruding from the bottom wall portion 12 of the appliance body 2 toward the movable part 70 side, or another part attached to the appliance body 2. In short, the existing parts to be prevented from interfering include all protrusions protruding from the bottom wall portion 12 of the appliance body 2 toward the terminal block holding portion 50 side.

[0088] The terminal block holding portion 50 may be configured such that, as described above, it does not have the base portion 60 and the movable part 70 is directly rotatably connected to the bottom wall portion 12 of the appliance body 2. In this configuration, since the movable part 70 has the movable part second hole 71b as the interference prevention hole 50b, the terminal block holding portion 50 can avoid interference with the protrusion protruding from the bottom wall portion 12 of the appliance body 2 toward the terminal block holding portion 50 side.

[0089] (Expansion of the applicable range of the construction target object) The pitches of the plurality of mounting bolts 10 in the mounted part W vary depending on the property as described above. As shown in FIG. 4, since the instrument body 2 has two sets of bolt through-holes 12c with different pitches, it can be applied to properties with pitches P1 and P2. That is, the instrument body 2 can be installed on various properties and can be made highly versatile. Note that the number of bolt through-holes 12c is not limited to two sets of four, and a plurality of additional ones may be provided.

[0090] As described above, the lighting device 1 according to the embodiment includes an instrument body 2 having a bottom wall portion 12 in which a second wire through-hole 12b through which the electric wire 110 is passed is formed, and a plate-shaped movable portion 70 that is attached to the bottom wall portion 12 so as to face the bottom wall portion 12 and has a movable portion first hole 71a formed at a position facing the second wire through-hole 12b, and a second terminal block 80 provided with an input portion 82 to which an end portion of the electric wire 110 passed through the second wire through-hole 12b and the movable portion first hole 71a is connected. The second terminal block 80 is fixed to an installation surface 70b on the side opposite to the facing surface 70a facing the bottom wall portion 12 of the movable portion 70 so that the input portion 82 is exposed in the movable portion first hole 71a. The movable portion 70 is rotatably connected to the bottom wall portion 12 of the instrument body 2 so that its posture can be changed between a use posture in which the facing surface 70a faces the bottom wall portion 12 and a construction posture in which the facing surface 70a is orthogonal or inclined to the surface direction of the bottom wall portion 12. The bottom wall portion 12 has a protruding portion protruding toward the terminal block holding portion 50, and the terminal block holding portion 50 has an interference prevention hole 50b for avoiding interference with the protruding portion.

[0091] As a result, the lighting device 1 is fixed to the installation surface 70b of the movable part 70 such that the input part 82 of the second terminal block 80 is exposed in the first hole 71a of the movable part in the use posture of the movable part 70. For this reason, in the lighting device 1, when the movable part 70 is in the use posture, the input part 82 of the second terminal block 80 is also exposed in the second wire passing hole 12b. Therefore, when the movable part 70 is in the use posture, the lighting device 1 can hold the electric wire 110 in a state of being pushed into the back side of the second wire passing hole 12b, and can reduce the installation space of the electric wire 110 in the lighting device 1. Further, the terminal block holding part 50 has an interference prevention hole for avoiding interference with the protruding part of the bottom wall part 12 of the appliance body 2. For this reason, compared with a configuration having no interference prevention hole 50b, the terminal block holding part 50 can relax the restriction on the installation position of the terminal block holding part 50 with respect to the appliance body 2, and has a high degree of installation freedom. Further, since the movable part 70 to which the second terminal block 80 is fixed is rotatable with respect to the bottom wall part 12 of the appliance body 2, during the construction of connecting the electric wire 110 to the second terminal block 80, when the movable part 70 is in the construction posture, a construction space can be secured around the input part 82 of the second terminal block 80. For this reason, in the lighting device 1, it becomes easier to connect the electric wire 110 to the input part 82 of the second terminal block 80, and the workability can be improved.

[0092] The interference prevention hole 50b is a second hole of the movable part formed in the movable part 70.

[0093] As a result, the lighting device 1 can avoid interference with the protruding part of the bottom wall part 12 in the movable part 70.

[0094] A plurality of bolt passing holes 12c for passing the mounting bolts 10 fixed to the mounted part W are formed in the bottom wall part 12 of the appliance body 2 corresponding to pitches with different fixing intervals of the mounting bolts 10.

[0095] As a result, the lighting device 1 can be installed on various objects.

[0096] The bottom wall part 12 is in the shape of a long plate, and the second wire passing hole 12b is formed at the central part in the short side direction of the bottom wall part 12.

[0097] Thus, when the lighting device 1 drills a hole for passing the electric wire 110 through the mounted part W, it is easy to determine where to drill the hole, and the hole drilling during construction can be facilitated.

[0098] The input part 82 has an input-side insertion hole 82a1 into which the end of the electric wire 110 is inserted, and the insertion direction of the input-side insertion hole 82a1 in the use posture is the same as the insertion direction of the electric wire 110 in the second wire passing hole 12b and the movable part first hole 71a.

[0099] Thus, in the lighting device 1 in the use state, the electric wire 110 passed through the second wire passing hole 12b is inserted into the input-side insertion hole 82a1 of the second terminal block 80 without being bent. Therefore, since the lighting device 1 does not need to secure a space for bending the electric wire 110 in the internal space S1 of the fixture main body 2, the installation space of the electric wire 110 can be reduced.

[0100] In addition, although the electric wire 110 has been described as a fire-resistant cable in the present embodiment, it is not limited thereto, and a cable with a small allowable bending radius may also be used. Further, the structure of the present embodiment is not limited to the cable used for the emergency lighting fixture, and may be applied to the cable used for general lighting. However, since a cable with a large allowable bending radius, such as a fire-resistant cable, requires a large space for installation in the internal space S1 of the fixture main body, it is desirable to be adapted to the lighting device 1 using a cable with a large allowable bending radius.

[0101] The movable part 70 is in the shape of a long plate and is rotatably connected to the bottom wall part 12 at one end in the longitudinal direction X.

[0102] As a result, compared with a configuration in which the movable part 70 is rotatably connected to the bottom wall part 12 at one end in the short side direction Y, the lighting device 1 can increase the distance between the second wire passing hole 12b and the first hole 71a of the movable part when in the construction posture. Thereby, the lighting device 1 can secure a construction space during construction, can insert the wire 110 into the input side insertion hole 82a1 of the second terminal block 80 while maintaining a large bending radius, and can improve the workability related to the connection of the wire 110 to the second terminal block 80.

[0103] The movable part 70 has a first hole 71a of the movable part at the other end in the longitudinal direction X.

[0104] As a result, compared with a configuration in which the first hole 71a of the movable part has the first hole 71a of the movable part at one end in the longitudinal direction X of the movable part 70, that is, near the rotation connection part, the lighting device 1 can increase the distance between the second wire passing hole 12b and the first hole 71a of the movable part when in the construction posture. Thereby, the lighting device 1 can secure a construction space during construction, can insert the wire 110 into the input side insertion hole 82a1 of the second terminal block 80 while maintaining a large bending radius, and can improve the workability related to the connection of the wire 110 to the second terminal block 80.

[0105] The appliance body 2 includes a normal first lighting fixture 3 and an emergency second lighting fixture 4. The second terminal block 80 is a terminal block for the second lighting fixture 4 and has an output part 83 to which a wiring 42 electrically connected to the second lighting fixture 4 is connected.

[0106] As a result, the lighting device 1 can supply an emergency power source from the output part 83 of the second terminal block 80 to the emergency second lighting fixture 4 provided separately from the normal first lighting fixture 3 via the wiring 42.

[0107] The appliance body 2 has a pair of side wall portions 13 protruding from both ends in the short side direction of the long plate-shaped bottom wall portion 12 so as to face each other, and a concave lighting fixture housing portion 18 extending in the longitudinal direction of the bottom wall portion 12 is formed by the bottom wall portion 12 and the pair of side wall portions 13. The first lighting fixture 3 is long and is disposed in the lighting fixture housing portion 18, and a first terminal block 7 for the first lighting fixture 3 electrically connected to the first lighting fixture 3 is attached to the bottom wall portion 12.

[0108] Thereby, the lighting device 1 can supply power to the long first lighting fixture 3 housed in the lighting fixture housing portion 18 via the first terminal block 7.

[0109] When the terminal block for the first lighting fixture 3 is the first terminal block 7 and the terminal block fixed to the movable portion 70 is the second terminal block 80, the first terminal block 7 and the second terminal block 80 are attached to the bottom wall portion 12 adjacent to each other.

[0110] Thereby, compared with a configuration in which the first terminal block 7 and the second terminal block 80 are attached to the bottom wall portion 12 separately, the lighting device 1 can more easily perform wiring work collectively and can improve workability.
