Summary of the Invention

Problems to be Solved by the Invention

[0004] In the lighting fixture of Patent Document 1, inside the recess, there are also stored fixtures such as bolts for attaching the instrument body to the attachment portion, a wire cable drawn in to receive power supply from a commercial power source provided outside the lighting fixture, and attachment means for attaching the light source unit to the instrument body. Further, inside the recess, a plurality of electric wires for electrically connecting members to each other are also accommodated, and it is conceivable that the members and electric wires accommodated inside the recess interfere with each other.

[0005] Also, the recess is formed to have the same dimensions as the instrument body in the longitudinal direction, and the light source unit and the emergency light source unit are arranged side by side in the longitudinal direction in the recess. During normal use, only the light source unit is lit. Therefore, when the emergency light source unit is arranged in the longitudinal direction, the light emitting area becomes smaller with respect to the longitudinal length of the fixture body. Further, when the fixture length is made the same as that of a normal lighting fixture, the light source unit must be shortened when the emergency light source unit is arranged in the longitudinal direction.

[0006] An object of the present invention is to provide a lighting device including an emergency light source unit, a member housed in a recess, and a lighting device that suppresses interference of electric wires.

[0007] Another object of the present invention is to provide a lighting device including an emergency light source unit that maintains a light emitting area during normal use.

Means for Solving the Problems

[0008] The lighting device of this invention is a long light source unit, a long main body recess in which the light source unit is detachably attached and that houses a part of the light source unit, a housing portion that is arranged adjacent to the main body recess in the short side direction of the main body recess and that houses a storage battery, an emergency lighting device that charges the storage battery, and an emergency light source portion that is lit by the power of the storage battery, and includes.

Effects of the Invention

[0009] In the lighting device of the present invention, since the housing portion houses a storage battery, an emergency lighting device that charges the storage battery, and an emergency light source portion that is lit by the power of the storage battery, interference of members housed in the main body recess and electric wires can be suppressed.

[0032] Of the side faces 214 of each unit, the unit side face 214-5 facing the first side face 112 of the main body recess 110 is the appliance adjacent wall portion 215. The appliance adjacent wall portion 215 is formed in a shape for arranging the electric wires for input / output to the emergency lighting device 230 and for inserting the storage battery 240. Specifically, the appliance adjacent wall portion 215 has a shape obtained by cutting off portions a, b, c, d, e, f, g, h from the rectangular shape a, i, j, h. This "portion a, b, c, d, e, f, g, h" is denoted as the opening portion 215C. The height in the Z1 direction from the unit front face 213 is dimension H (FIG. 10) for any of the unit side faces 214-1, 214-3, 214-4, but the height of the appliance adjacent wall portion 215 is lower than dimension H. Among the appliance adjacent wall portion 215, the concave portions c, d, e, f are called wall recesses 215A, and the portions with a certain height b, c are called long wall portions 215B. As shown in FIG. 8, when the emergency light source unit 200 is attached to the main body recess 110, the appliance adjacent wall portion 215 forms the first communication portion 112a and the wire opening 216, and the second communication portion 112b and the storage battery opening 217. When the emergency light source unit 200 is fixed to the main body recess 110, the wall recess 215A and the long wall portion 215B of the unit decorative portion 212 are in the attachment state shown by the two-dot chain line at the positions of the first communication portion 112a and the second communication portion 112b of the first side face 112 in FIG. 10.

[0033] That is, the wire opening 216 is formed by a part of the upper ends b to c of the long wall portion 215B being located at the notched lower end of the first communication portion 112a. Also, the storage battery opening 217 is formed by the upper ends c to f of the wall recess 215A being located at the notched lower end of the second communication portion 112b. Note that the side height H of the unit decorative portion 212 shown in FIG. 10 is such a height that the lens 223 of the emergency light source portion 220 is arranged on the side of the gripping portion 13b of the light source unit 10 as shown in FIG. 4. Therefore, it is a position where the influence of the light distribution given by the light source unit 10 and the emergency light source portion 220 on each other is small.

[0034] As shown in FIG. 10, the emergency light source unit 220 includes a substrate 222 on which a light emitting element 221 is mounted, a socket 222a, a glass lens 223 disposed in front of the mounted light emitting element 221, and a light source installation base 224 having a substantially U-shaped form on which the substrate 222 is installed. The emergency light source unit 220 is attached to the light source installation base 224 by a light source retainer 223a. In the emergency light source unit 220, the lens 223 protrudes in the Z2 direction (FIG. 2(b)) from the lens opening 213a. The lens 223 is a lens that distributes the light emitted by the light emitting element 221 over a wide angle and has a light distribution characteristic for irradiating the necessary range as an emergency light source unit. In this embodiment, it has a batwing-shaped light distribution characteristic. The light source installation base 224 also has a heat dissipation effect, and an emergency lighting device 230 is disposed inside thereof.

[0035] As shown in FIG. 10, the emergency lighting device 230 includes an emergency lighting device main body 231 having a substantially rectangular parallelepiped shape and a device-side connection portion 232.

The device-side connector 232b is connected to a storage battery-side connector 242b described later. FIG. 17 is a wiring diagram of the appliance main body and the emergency light source unit. FIG. 17 corresponds to a view taken in the direction of arrow K in FIG. 8, with the unit decorative portion 212 removed, the lens 223, the light source retainer 223a, etc. being exposed, and the first side surface portion 112 and the second side surface portion 113 of the appliance main body 100 being cut halfway. As shown in FIG. 17, in a state where the emergency lighting device 230 is disposed laterally of the main body recess 110, an electric wire 300 is drawn from a terminal block 130 through a wire opening 216. The electric wire 300 is an electric wire that is connected to the terminal block 130 to receive power supply. Further, the device-side connection portion 232 is disposed outside the unit outer shell portion 210.

[0036] When an external power source such as a commercial power supply is being supplied normally, the emergency lighting device 230 charges the storage battery 240 with the power from the commercial power supply. When the power supply from the commercial power is stopped due to a power outage or the like, the emergency light source unit 220 is lit with the power from the storage battery 240. As shown in FIG. 12, the emergency lighting device 230 is disposed inside the light source mounting base 224.

[0037] As shown in FIG. 10, the storage battery 240 has a storage battery main body 241 having a substantially rectangular parallelepiped shape and a storage battery side connection portion 242. The storage battery side connection portion 242 has a storage battery side electric wire 242a and a storage battery side connector 242b. The storage battery side connector 242b is connected to the device side connector 232b of the emergency lighting device 230. The storage battery side electric wire 242a is connected to the storage battery side connector 242b. The storage battery 240 is disposed inside the U-shaped storage battery holding member 243 shown in FIGS. 10 and 12. The storage battery holding member 243 is arranged such that the opening 243a of the storage battery holding member 243 is in a communication position with the storage battery opening 217. The storage battery 240 is housed inside the battery holding member 243 so as to be insertable and removable through the storage battery opening 217 in a state where the emergency light source unit 200 is disposed in the main body recess 110. The storage battery 240 is housed inside the housing portion 2000 at a position sandwiching the power supply hole 111a together with the terminal block 130 in the longitudinal direction X. Further, as shown in FIG. 17, the storage battery side connector 242b of the storage battery side connection portion 242 is arranged to be outside the unit outer shell portion 210 through the storage battery opening 217.

[0038] The inspection switch 250 shown in Fig. 10 has an inspection switch body 251 in which a substrate with switch terminals (not shown) mounted inside is disposed, and a pull rod 252 that is connected to the switch terminals and protrudes operably from the inspection switch body 251. The inspection switch 250 is held by a part of the light source mounting base 224, and as shown in Fig. 8, the pull rod 252 is disposed so as to protrude from the switch opening 212b of the unit outer shell portion 210. The inspection switch 250 is a switch for inspecting whether the storage battery 240 is normal or not. When the pull rod 252 of the inspection switch 250 is pulled, the emergency light source unit 220 is lit emergently with the power of the storage battery 240 for a set time.

[0039] (Mounting mechanism of the emergency light source unit 200) With reference to Figs. 13 to 16, the mounting mechanism of the emergency light source unit 200 to the main body recess 110 will be described. (1) First, as shown in Fig. 13, the operator abuts the bottom surface mounting portion 211b of the unit bottom surface portion 211 of the emergency light source unit 200 against the main body bottom surface portion 111 of the main body recess 110. At this time, the operator disposes the emergency light source unit 200 so that the power supply hole 111a of the main body bottom surface portion 111 and the bottom surface power supply hole 211ba communicate with each other. The bottom surface mounting portion 211b is formed to be substantially equal to the length of the main body bottom surface portion 111 in the short side direction Y. Therefore, the bottom surface mounting portion 211b abuts against the main body bottom surface portion 111 over substantially the entire length in the short side direction Y of the main body bottom surface portion 111. (2) Next, the operator aligns the first fixing hole 211bb and the second fixing hole 211bc of the unit bottom surface portion 211 with the first fixture-side fixing hole 111bb and the second fixture-side fixing hole 111bc of the main body recess 110, and in the communicating state, attaches the emergency light source unit 200 to the main body bottom surface portion 111 at these four locations with a mounting member (such as a screw or a rivet). Thereby, the emergency light source unit 200 is fixed to the main body bottom surface portion 111. In this embodiment, a screw 501 is used as the mounting member (Fig. 16). In this attached state, the bottom surface mounting portion 211b is in a state of abutting against the main body bottom surface portion 111.

[0040] In the mounting process as described above, the emergency light source unit 200 is fixed to the main body recess 110. When the emergency light source unit 200 is fixed to the main body recess 110, it is in the following states (1) to (3). (1) Over substantially the entire length of the main body bottom surface portion 111 in the short side direction Y, the bottom surface mounting portion 211b is in contact with the main body bottom surface portion 111. (2) At the first fixing hole 211bb on the second side surface portion 113 side, which is located farther from the optical axis 220a (FIG. 16) of the emergency light source portion 220 than the optical axis 220a of the emergency light source portion 220 in the short side direction Y of the main body bottom surface portion 111, the bottom surface mounting portion 211b of the emergency light source unit 200 is fixed to the main body bottom surface portion 111. (3) As shown in FIG. 16, at the second fixing hole 211bc, which is between the optical axis 220a of the emergency light source portion 220 and the first fixing hole 211bb in the short side direction Y of the main body bottom surface portion 111, the bottom surface mounting portion 211b is fixed to the main body bottom surface portion 111.

[0041] With the mounting configurations (1) to (3) described above, the emergency light source unit 200 can be stably mounted to the main body recess 110. That is, in the above (1), by having the bottom surface mounting portion 211b in contact with the main body bottom surface portion 111 over "substantially the entire length in the short side direction Y", the weight of the emergency light source unit 200 can be shared and transmitted to the main body recess 110, so that partial deformation of the main body recess 110 can be suppressed. Therefore, it is possible to suppress the emergency light source unit 200 from sagging in the Z2 direction (FIG. 16) due to partial deformation of the main body recess 110. In the above (2), the bottom surface mounting portion 211b is fixed on the second side surface portion 113 side in the short side direction Y of the main body bottom surface portion 111. Thereby, due to the weight of the emergency light source unit 200, it is possible to suppress the second side surface portion 113 of the unit bottom surface portion 211 from lifting in the Z1 direction (FIG. 16), and to suppress the emergency light source unit 200 from sagging in the Z2 direction. The above (3) is fixed on the first side surface portion 112 side in the short side direction Y of the main body bottom surface portion 111. Thereby, it is possible to suppress the unit bottom surface portion 211 from deforming due to storage conditions, vibration, etc., and the emergency light source unit 200 from lifting in the Z1 direction. The deformation of the main body recess 110 caused by the mounting of the emergency light source unit 200 can be prevented by the above (1) to (3).

[0042] With the arrangement of the first fixing hole 211bb and the second fixing hole 211bc described above, the emergency light source unit 200 can be stably attached to the main body recess 110. Further, by providing ribs on the unit bottom surface portion 211 or providing a reinforcing portion by hemming, the rigidity can be further increased and stability can be achieved.

[0043] In this embodiment, the emergency light source unit 200 is attached to the main body recess 110 after assembly, but the emergency light source unit 200 may be completed by attaching each part after attaching the unit bottom surface portion 211 to the main body recess 110.

[0044] (Regarding the wiring of the appliance main body 100) The wiring of the appliance main body 100 will be described with reference to FIG. 17. The emergency light source unit 200 is arranged adjacent to the side in the short-side direction Y of the first side surface portion 112 of the main body recess 110 of the appliance main body 100. The terminal block 130 is positioned in the X1 direction from the power supply hole 111a with the power supply hole 111a of the main body recess 110 as the approximate center. At this time, the output terminal 131b of the terminal block 130 is arranged so as to face outward in the X1 direction, that is, in the longitudinal direction X. Further, a first communication portion 112a and a second communication portion 112b are provided in the first side surface portion 112. The first communication portion 112a is provided on the X1 direction side of the power supply hole 111a, and the second communication portion 112b is provided on the X2 direction side of the power supply hole 111a. That is, the first communication portion 112a and the second communication portion 112b form the wire opening 216 and the battery opening 217, respectively. As shown in FIG. 17, in the longitudinal direction X, the power supply hole 111a is positioned between the wire opening 216 and the battery opening 217.

[0045] The wiring configuration shown in FIG. 17 is as follows (a) to (e). (a) The power supply line 400 drawn from the power supply hole 111a is connected to the input terminal 131a provided on the X2 direction side of the terminal block 130. (b) One end of the electric wire 300 is connected to the output terminal 131b of the terminal block 130, and the other end of the electric wire 300 is connected to the emergency lighting device 230 of the emergency light source unit 200. A terminal block side connection part 132 is connected to the output terminal 131b of the terminal block 130. This terminal block side connection part 132 is connected to the light source unit side connection part 16b of the light source unit 10 and supplies power to the lighting device 16. (c) In the emergency lighting device 230, the device side electric wire 232a of the device side connection part 232 passes through the wire opening 216, and the device side connector 232b is arranged inside the main body recess 110 together with a part of the device side electric wire 232a. (d) The battery opening 217 is provided on the X2 direction side of the power supply hole 111a. The battery side electric wire 242a of the battery side connection part 242 passes through the battery opening 217, and the battery side connector 242b is arranged inside the main body recess 110 together with a part of the battery side electric wire 242a. (e) The device side connector 232b of the device side connection part 232 and the battery side connector 242b of the battery side connection part 242 are connected on the X2 direction side of the power supply hole 111a. That is, the device side connector 232b and the battery side connector 242b are connected at a position inside the main body recess 110 that sandwiches the power supply hole 111a together with the terminal block 130 in the longitudinal direction X. The lengths of the device side electric wire 232a and the battery side electric wire 242a are such that the device side connector 232b and the battery side connector 242b can be connected and are not too long. As shown in FIG. 17, a part of the lighting device side electric wire 232a and the battery side electric wire 242a is fixed to the main body bottom surface part 111 by the wire support part 111c.

[0046] As shown in FIG. 17, in a state where the light source unit 10 is attached to the appliance main body 100, in the short side direction Y, the engaging part 13c of the cover 13 of the light source unit 10 is arranged on the side of the battery 240. By this arrangement, there is an effect that the battery 240 can be prevented from unintentionally coming out of the battery opening 217 of the unit outer shell part 210 and into the inside of the main body recess 110. Moreover, if the lighting device 16 is arranged so as to face the battery opening 217, the above effects can be further improved. That is, the battery 240 is housed in the housing portion 2000, and a part of the light source unit 10 housed in the main body recess 110 blocks the movement from the housing portion 2000 to the main body recess 110 through the battery opening 217. The "part of the light source unit 10" that blocks the movement of the battery 240 is the engaging portion 13c of the cover 13 or the lighting device 16 in the above example.

[0047] (Regarding the normal lighting operation) Next, the normal lighting operation will be described. During normal times (when power is supplied from the commercial power supply), power is supplied to the lighting device 16 via the terminal block 130, and the light source unit 10 lights up. At this time, the emergency lighting device 230 supplies the power supplied via the electric wire 300 to the battery 240 to charge the battery 240.

[0048] (Regarding the emergency lighting operation) Next, the emergency lighting operation will be described. During an emergency, the power supply to the lighting device 16 is stopped, and the light source unit 10 goes out. An emergency means a time when the power supply from the commercial power supply is stopped for some reason such as a power outage. When the power supply from the electric wire 300 to the emergency lighting device 230 is stopped, it switches to the power supply from the battery 240, supplies power to the emergency light source unit 220, and the emergency light source unit 220 lights up.

[0049] <***Effects of the present embodiment (wiring and appliance body)***> (1) In the lighting device 1, the fixture main body 100 includes a main body recess 110 that holds the light source unit 10 and an emergency light source unit 200. Since the housing portion 2000 of the emergency light source unit 200 is arranged on the side in the short side direction Y of the main body recess 110, when providing the emergency light source unit 200, it is not necessary to increase the overall length of the lighting device 1 in the longitudinal direction X or shorten the overall length of the light source unit as in the case of providing the housing portion 2000 adjacent in the longitudinal direction X. Further, since the lighting device 1 can use a light source unit 10 having a length substantially equal to the length of the lighting device 1 in the longitudinal direction X, even when the emergency light source unit 200 is provided, the same light emitting area as when the emergency light source unit 200 is not provided can be maintained. (2) The fixture main body 100 has a main body recess 110 to which the light source unit 10 is attached, and the emergency light source unit 200 is provided separately. By forming a component member that serves as a light source in an emergency as the emergency light source unit 200 separately from the main body recess 110, the assemblability of the lighting device can be improved. (3) Further, since they are separate, the unit outer shell portion 210 can be formed of a material different from that of the main body recess 110. Therefore, the emergency light source unit 200 can be configured with a material suitable for the application, such as a material having excellent fire resistance, as an emergency light source. Also, by configuring only the unit outer shell portion 210 with a specific application material, the cost can be suppressed compared to configuring the entire fixture main body 100 with the specific application material. (4) Also, by adopting the wiring configuration as in (a) to (e) above, it is possible to prevent the power supply line 400, each member, and the electric wire 300 from interfering with each other. In particular, the configuration shown in (d) above facilitates the insertion and removal of the storage battery 240 into and from the emergency light source unit 200. Also, with the configuration in (e) above, the connection and disconnection operations between the device-side connector 232b and the storage battery-side connector 242b can be performed without interfering with the power supply line 400. Therefore, the replacement maintenance of the storage battery 240 becomes easy. (5) Further, when the lighting device 16 is provided in the X2 direction from the power supply hole 111a, the space inside the main body recess 110 can be effectively utilized in a state where the light source unit 10 is attached to the fixture main body 100. (6) Also, by aggregating electrical components such as the terminal block 130 and the emergency light source unit 200 between the paired mounting holes 111b and around the power supply hole 111a, it is possible to suppress the lengthening of the electric wires for mutual connection. Furthermore, interference between the aggregated components and the mounting mechanism composed of the mounting tools (such as bolts for fixing to the ceiling) or the spring 140 and the connecting tool 15 can be prevented. Furthermore, the positions where the mounting holes 111b and the power supply holes 111a are provided may be the same as those of the lighting device without the emergency light source unit 200. That is, the lighting device 1 can share the appliance main body 100 (main body recess 110) with the lighting device without the emergency light source unit 200. Therefore, without changing the positions of the "mounting tools such as bolts for attaching the appliance main body 100 to the ceiling or the like and the power supply line 400 drawn into the appliance main body 100" provided for the lighting device without the emergency light source unit 200, it can be used as it is, so the workability is good. (7) Since the emergency light source unit 200 arranges the device-side connection part 232 and the battery-side connection part 242 outside the unit outer shell part 210, the emergency lighting device 230 and the battery 240 can be easily connected. Also, the connection state can be easily released.

[0050] (Modifications and Supplements) In this embodiment, the appliance main body 100 has been described with the main body recess 110 having a trough shape, but it may also be the inverted Fuji-shaped lighting device 1A as shown in FIG. 18 or the embedded-shaped lighting device 1B as shown in FIG. 19. In the case of the inverted Fuji shape or the embedded shape, inclined reflection parts 114 are formed in pairs at the openings of the main body recess 110 (the openings p, q, r, s in FIG. 3), and a notch 114a is formed in one of the reflection parts 114 on the side where the accommodating part 2000 is arranged so that the emergency light source unit can be arranged. Although the shape of the notch 114a does not appear in FIG. 19, it is the same as in FIG. 18. Thus, the main body recess 110 includes the reflection part 114 in which the region where the accommodating part 2000 penetrates is cut out as the notch 114a.

[0051] Also, like the case of the embedded shape in FIG. 19, the height dimension H(B) of the emergency light source unit 220 of the emergency light source unit 200 may be increased so as to protrude from the reflecting portion 114. By causing the emergency light source unit 220 to protrude from the reflecting portion 114, the light distribution characteristics of the emergency light source unit 220 can be ensured. As shown in FIG. 19, the emergency light source unit 220B of the lighting device 1B protrudes from the accommodating portion 2000B, and the main body recess 110 has a region through which the emergency light source unit 220B passes cut out.

[0052] In the present embodiment, the terminal block 130 has a plurality of output terminals 131b and is wide in the lateral direction Y. Therefore, when it is desired to connect a plurality of lighting devices 1 in the longitudinal direction X, there may be a case where there is no space for arranging feed wiring such as an F cable between the terminal block 130 and the first side surface portion 112 or the second side surface portion 113. Also, when the feed wiring is arranged in front of the battery opening 217, it hinders the accommodation and removal work of the battery 240. Therefore, it is preferable to form a feed wiring opening 113a in the second side surface portion 113 between the power supply hole 111a and the terminal block 130. FIG. 17 shows a case where the main body recess 110 has a feed wiring opening 113a, which is a feed wiring opening, formed in the second side surface portion 113, which is the side surface portion on the side opposite to the accommodating portion 2000 in the lateral direction Y. By providing the feed wiring opening 113a in the second side surface portion 113, the side of the second side surface portion 113 side of the main body recess 110 can be used as a space for feed wiring. Therefore, interference between the feed wiring and the battery opening 217 and other component members can be suppressed.

[0053] In the present embodiment, the lighting device 1 has been described with respect to a shape in which the light source unit 10 has a coupler 15 and a lighting device 16, and the fixture main body 100 has a spring 140. However, a configuration in which the light source unit 10 has a spring 140 and the fixture main body 100 has a coupler 15 and a lighting device 16 may also be used. In addition, when the lighting device 16 is provided on the instrument body 100, in the longitudinal direction X in FIG. 17, it is preferably installed in the X2 direction from the second communication part 112b or in the X1 direction from the terminal block 130 so that the lighting device 16 and the storage battery 240 do not interfere with each other.

[0054] In the present embodiment, the shape in which the power supply hole 111a is provided substantially at the center in the longitudinal direction X of the main body recess 110 has been described. However, the position where the power supply hole 111a is formed does not have to be substantially at the center in the longitudinal direction X. In the longitudinal direction X of the main body recess 110, it is sufficient that the terminal block 130 is provided on one side of the power supply hole 111a and the second communication part 112b is provided on the other side.

[0055] In addition, in the present embodiment, the main body recess 110 and the accommodation part 2000 form a wire opening 216 which is an opening through which the device-side electric wire 232a of the device-side connection part 232 passes from the accommodation part 2000 to the main body recess 110. Further, the main body recess 110 and the accommodation part 2000 form a storage battery opening 217 which is an opening through which the storage battery 240 can pass from the accommodation part 2000 to the main body recess 110 at a position sandwiching the power supply hole 111a together with the terminal block 130 in the longitudinal direction X. That is, the wire opening 216 is formed by the first communication part 112a and the open part 215C of the instrument adjacent wall part 215, and the storage battery opening 217 is formed by the second communication part 112b and the open part 215C of the instrument adjacent wall part 215.

[0056] However, it is not limited to this. As a configuration in which the main body recess 110 and the accommodation part 2000 form the wire opening 216 or the storage battery opening 217, there are the following cases. When the open part 215C of the instrument adjacent wall part 215 is not open and has a shape of a single plate with a height H (FIG. 10), an opening corresponding to the wire opening 216 and an opening corresponding to the storage battery opening 217 are formed in the instrument adjacent wall part 215 and the first side surface part 112, and the opening of the instrument adjacent wall part 215 and the opening of the first side surface part 112 are communicated. If one opening has the size of the wire opening 216 or the storage battery opening 217, the other opening may be larger than that. Alternatively, a configuration may be adopted in which either the main body recess 110 or the accommodating portion 2000 is formed with a wire opening 216, which is an opening through which the device-side electric wire 232a of the device-side connection portion 232 passes from the accommodating portion 2000 to the main body recess 110. Alternatively, a configuration may be adopted in which either the main body recess 110 or the accommodating portion 2000 is formed with a battery opening 217, which is an opening through which the battery 240 can pass from the accommodating portion 2000 to the main body recess 110 at a position sandwiching the power supply hole 111a together with the terminal block 130 in the longitudinal direction X. As an example of these, when there is no appliance adjacent wall portion 215, that is, in FIG. 10, the portion of "ibcdefgj" of the appliance adjacent wall portion 215 is absent, while on the first side surface portion 112, an opening corresponding to the wire opening 216 and an opening corresponding to the battery opening 217 are formed.

[0057] When the main body recess 110 and the accommodating portion 2000 form the battery opening 217, the positional relationship in the longitudinal direction X among the battery 240, the terminal block 130, the power supply hole 111a, and the battery opening 217 may be configured as follows. (a1) The battery 240 is accommodated inside the accommodating portion 2000 at a position sandwiching either one of the terminal block 130 and the power supply hole 111a in the longitudinal direction X. And (a2) The main body recess 110 and the accommodating portion 2000 form a battery opening 217, which is an opening through which the battery 240 can pass from the accommodating portion 2000 to the main body recess 110, at the position where the battery 240 is accommodated in the longitudinal direction X. In the above (a1), the "position sandwiching the other together with either one of the terminal block 130 and the power supply hole 111a in the longitudinal direction X" means that when "either one" is the terminal block 130, the other is the power supply hole 111a, which corresponds to the case shown in FIG. 17, and the battery 240 and the terminal block 130 sandwich the power supply hole 111a. And as in the above (a2), the main body recess 110 and the accommodating portion 2000 form the battery opening 217 at the accommodation position of the battery 240 in the longitudinal direction X, which corresponds to FIG. 17. Also, when "either one" is the power supply hole 111a, the other is the terminal block 130. With respect to FIG. 17, in the longitudinal direction X, the battery 240 and the power supply hole 111a sandwich the terminal block 130. This configuration is such that the power supply hole 111a and the terminal block 130 are swapped in the longitudinal direction X in FIG. 17. Also in this case, as in the above (a2), the main body recess 110 and the housing portion 2000 may form a battery opening 217 at the housing position of the battery 240 in the longitudinal direction X. With the configurations of the above (a1) and (a2), the battery 240 can be easily inserted into and removed from the emergency light source unit 200.

[0058] When the battery opening 217 is formed in either the main body recess 110 or the housing portion 2000, the positional relationship in the longitudinal direction X of the battery 240, the terminal block 130, the power supply hole 111a, and the battery opening 217 may also be configured as follows. (b1) The battery 240 is housed inside the housing portion 2000 at a position that sandwiches the other one between either one of the terminal block 130 and the power supply hole 111a in the longitudinal direction X. And, (b2) In either the main body recess 110 or the housing portion 2000, at the position where the battery 240 is housed in the longitudinal direction X, a battery opening 217, which is an opening through which the battery 240 can pass from the housing portion 2000 to the main body recess 110, is formed. The above (b1) is the same as the content described in the above (a1). And as in the above (b2), a configuration in which the battery opening 217 is formed at the housing position of the battery 240 in the longitudinal direction X in either the main body recess 110 or the housing portion 2000 may also be used. With the configurations of the above (b1) and (b2), the battery 240 can be easily inserted into and removed from the emergency light source unit 200.

[0059] Also, the wire opening 216 may be configured as follows. (c1) The device-side connector 232b and the battery-side connector 242b are connected at a position inside the main body recess 110 that sandwiches the other one between either one of the terminal block 130 and the power supply hole 111a in the longitudinal direction X. The position inside the main body recess 110 that sandwiches either one of the terminal block 130 and the power supply hole 111a in the longitudinal direction X is the same as in the case of (a1) above. When "either one" is the terminal block 130, the other is the power supply hole 111a, which corresponds to the case shown in FIG. 17, and the "device-side connector 232b and the battery-side connector 242b" are configured to sandwich the power supply hole 111a in the longitudinal direction X together with the terminal block 130. Also, when "either one" is the power supply hole 111a, the other is the terminal block 130, and in the longitudinal direction X with respect to FIG. 17, the "device-side connector 232b and the battery-side connector 242b" are configured to sandwich the terminal block 130 together with the power supply hole 111a. This configuration is such that the power supply hole 111a and the terminal block 130 are interchanged in the longitudinal direction X in FIG. 17. With the configuration of (c1), the work of connecting and disconnecting the device-side connector 232b and the battery-side connector 242b by the operator becomes easier.

[0060] In addition, in the present embodiment, the shape in which the housing portion 2000 of the emergency light source unit 200 is arranged on the lateral side in the short hand direction of the main body recess 110 of the instrument main body 100 has been described. The housing portion 2000 houses the emergency light source portion 220, the emergency lighting device 230, the storage battery 240, the inspection switch 250, etc. that constitute the emergency light source unit 200, but not all of them, and at least any one of the emergency light source portion 220 etc. that constitute the emergency light source unit 200 may be housed. Also, the housing portion 2000 may house some component that is not a component of the emergency light source unit. As some component, a functional component such as a sensor or a pulse switch, or an electrical component may be housed.

[0061] In addition, in the present embodiment, the shape in which the unit bottom surface portion 211 has the bottom surface arrangement portion 211a and the bottom surface attachment portion 211b has been described, but the bottom surface arrangement portion 211a and the bottom surface attachment portion 211b may be provided separately.

[0062] Embodiment 2. Embodiment 2 will be described with reference to FIGS. 20 to 24. Embodiment 2 has a configuration in which the lighting device 1 of Embodiment 1 further includes a battery cover 600 that closes the battery opening 217. By providing the battery cover 600, heat generated by the lighting device 16, the light emitter 11, etc. included in the light source unit 10 is prevented from being transmitted from the battery opening 217 into the interior of the accommodating portion 2000 constituted by the unit decorative portion 212 and the bottom surface arrangement portion 211a, thereby preventing the temperature of the battery from rising.

[0063] FIG. 20 is a perspective view showing the attachment of the battery cover 600 to the battery opening 217. FIG. 21 is a view showing the battery cover 600. FIG. 21(a) is a front view of the battery cover 600, and FIG. 21(b) is a side view of the battery cover 600. FIG. 22 shows the state before the attachment of the battery cover 600, and FIG. 23 shows the state after the attachment. FIG. 24 is a cross-sectional view showing the attached state of the battery cover 600, and is a cross-section for cutting the lid insertion piece 612 described later. FIG. 24 shows the relationship between the battery cover 600 and the battery 240. The display of the lid receiving portion 217b, the knurled screw, etc. described later is omitted, and the hatching of the lid body 610 is also omitted.

[0064] The battery cover 600 has a substantially square shape as shown in FIG. 21. The battery cover 600 has a lid main body portion 610 that is plate-shaped and fixed to the main body recess 110 so as to close the battery opening 217, and a lid buffer member 620 that has cushioning properties and is attached to one surface of the lid main body portion 610. As the lid buffer member 620, a member such as rubber or sponge can be used. The lid main body portion 610 has a lid fixing hole 611 for fixing the battery cover 600 to the main body recess 110 by a fixing member 701 such as a knurled screw, a lid insertion piece 612 to be inserted into the battery opening 217, and a wire notch portion 613 for avoiding the battery-side electric wire 242a.

[0065] In Embodiment 2, in the de portion of the wall recess 215A (FIG. 10), as shown in FIG. 22, an insertion groove 217a and a pair of lid receiving portions 217b are formed on both sides thereof. As shown in FIGS. 22 and 23, the battery lid 600 is attached to the battery opening 217 by inserting the lid insertion piece 612 into the battery opening 217 and fixing it to the first side surface portion 112 with a fixing member 701 through the lid fixing hole 611. Specifically, as described below with reference to FIGS. 22 and 23. The lid insertion piece 612 is pushed into the insertion groove 217a as shown by the arrow in FIG. 22. Also, point M is at the position of point m of the instrument adjacent wall portion 215, point N is at the position of point n of the instrument adjacent wall portion 215, point T is at the position of point t of the first side surface portion 112, and point U is at the position of point u of the first side surface portion 112.

[0066] At this time, when the battery lid 600 is attached to the battery opening 217, the lid buffer member 620 contacts the battery 240 disposed inside the housing portion 2000 as shown in FIG. 24. The battery 240 is stably fixed by being pressed against one side of the battery holding member 243 by the lid buffer member 620, and rattling against vibrations and the like is suppressed. Also, as shown in FIG. 23, the wire notch portion 613 forms an opening through which the battery side wire 242a of the battery 240 can pass between the battery lid 600 and the first side surface portion 112 in a state where the battery lid 600 is fixed to the first side surface portion 112.

[0067] The battery 240 housed in the housing portion 2000 may have its temperature (ambient temperature) increased by the heat radiation of the light emitter 11 and the lighting device 16 generated when the light source unit 10 attached to the main body recess 110 is lit in a state where the housing portion 2000 and the main body recess 110 communicate with each other through the battery opening 217. Although there is a risk that the performance of the battery 240 may deteriorate due to the temperature rise of the battery 240, by closing the battery opening 217 with the battery lid 600, the heat radiation from the light emitter 11 and the lighting device 16 can be blocked, the temperature rise of the battery 240 can be suppressed, and the performance degradation of the battery 240 can be prevented.

[0068] Furthermore, the battery cover 600 also has a function of preventing the battery 240 from inadvertently coming out of the battery opening 217 of the housing portion 2000. By providing the battery cover 600, the battery 240 can be stably housed in the housing portion 2000.

[0069] Note that the battery cover 600 may be attached not only by a fixing member 701 such as a knurled screw but also by an attachment method that engages and fixes with the battery opening 217.

[0070] Embodiment 3. FIG. 25 is a cross-sectional view of the embedded lighting device 1B of FIG. 19 and is a cross-sectional view showing the light distribution characteristics of the emergency light source unit 220. Embodiment 3 will be described with reference to FIG. 25. Embodiment 3 shows a more specific configuration of the lighting device 1B described in FIG. 19 of Embodiment 1 and is an embodiment regarding the installation position of the emergency light source unit 220 in the lighting device 1B.

[0071] In Embodiment 3, as shown in FIG. 25, the position of the lens 223 of the emergency light source unit 200 is set in the Z2 direction relative to the light source unit 10 so that the light distribution range A of the lens 223 does not interfere with the reflecting portion 114. With this configuration, a lighting device provided with the emergency light source unit 200 that ensures the light distribution characteristics of the emergency light source unit 220 can be provided. Note that the reflecting portion 114 is provided so as to be inclined from the longitudinal side 702 of the main body recess 110. This will be described below with reference to FIG. 25.

[0072] In the embedded lighting device 1B as shown in FIG. 25, if the emergency light source unit 220 (lens 223), which is a part of the light-emitting unit that emits light, is provided at approximately the same position as the light source unit 10 in the height direction Z, the light irradiated by the emergency light source unit 220 (lens 223) will also be controlled by the reflecting portion 114 that controls the light irradiated by the light source unit 10. As a result, the desired light distribution of the emergency light source cannot be obtained. In addition, when the desired light distribution of the emergency light source unit 220 cannot be ensured, it is necessary to increase the number of installed lighting devices 1B equipped with the emergency light source unit 200. Therefore, regarding the lighting device 1B shown in FIG. 19 of Embodiment 1, as shown in FIG. 25, with respect to the height direction Z of the emergency light source unit 200, the emergency light source unit 200 is arranged so as to protrude from the reflecting portion 114 in the anti-Z2 direction which is the irradiation direction of the light source unit 10.

[0073] More specifically, in the case of the emergency light source unit 220 in FIG. 25, since light is emitted from the lens 223, the lens is the light emitting portion of the light. Therefore, the lens 223 is arranged in the Z2 direction which is the irradiation direction of the light source unit 10 from the light source unit 10 and in the Z2 direction where the light distribution range A of the lens 223 is ensured without being blocked by the reflecting portion 114 from the lens 223. The lens 223 is incorporated into the emergency light source unit 200 as a component of the emergency light source unit 200, and the emergency light source unit 200 including the lens 223 is integral. Therefore, the above-mentioned "with respect to the height direction Z of the emergency light source unit 200, the emergency light source unit 200 is arranged so as to protrude from the reflecting portion 114 in the Z2 direction which is the irradiation direction of the light source unit 10." means this. Also, the Y-direction position of the lens 223 is related to ensuring the light distribution range A. The length direction X of the light source unit 10 is ensured by moving in the Y direction. Therefore, the emergency light source unit 220 (lens 223) is arranged at an XY-direction position where the light distribution range A does not interfere with the reflecting portion 114 and the end portion 114b of the reflecting portion. With this configuration, the light distribution characteristics of the emergency light source unit 220 are ensured.

[0074] In this way, by installing the light source unit 10 and the emergency light source unit 220 at separate positions and installing the emergency light source unit 220 at a height where the light distribution range does not interfere with the reflecting portion 114, the light distribution range of the emergency light source unit 220 can be ensured. Also, since the emergency light source unit 220 ensures the light distribution characteristics, it is possible to suppress an increase in the number of installed lighting fixtures equipped with the emergency light source unit 220.

[0075] In addition, if the light distribution range A of the emergency light source unit 220 is a position where it does not interfere with the reflecting portion 114 and the end portion 114b of the reflecting portion, in FIG. 25, it may be provided in the Z1 direction. Further, also in the Y direction which is the width direction, it may be provided outward away from the light source unit 10. By installing it on the outside in the width direction, it is possible to suppress the light distribution of the light source unit 10 from interfering with the emergency light source unit 200.

[0076] Further, the third embodiment can also be applied not only to the built-in type fixture but also to a lighting device provided with a reflecting plate formed obliquely from the side of the main body recess 110 of the lighting device 1 such as a fixture with a shade.

[0077] In the above-described embodiment, a lighting device having the following features has been described. A long light source unit, A long fixture body that is installed on the attachment portion and to which the light source unit is detachably attached, Electrical components that are arranged away from the longitudinal direction of the light source unit attached to the fixture body in a direction intersecting the longitudinal direction, A reflecting portion that is arranged along the longitudinal direction on the side of the light source unit and in which a region overlapping the electrical components is cut away, A lighting device comprising:

[0078] The reflecting portion is A lighting device that is inclined with respect to the attachment portion.

[0079] A long light source unit, A long main body recess in which the light source unit is detachably attached and at least a part of the light source unit is accommodated, Electrical components that are arranged away from the longitudinal direction of the light source unit accommodated in the main body recess in a direction intersecting the longitudinal direction, A lighting device comprising:

[0080] The lighting device further includes An illumination device including a reflecting portion that is disposed along the longitudinal direction on the side of the main body recess and in which a region overlapping the electrical component is cut away.

[0081] The reflecting portion is An illumination device that is inclined with respect to a mounting portion to which the illumination device is mounted.

[0082] The electrical component is An illumination device including a sensor component.
