Description

The present invention relates to a lighting fixture.
INDUSTRIAL APPLICABILITY The present invention is suitable for battery-powered lighting equipment and emergency lighting equipment.
INDUSTRIAL APPLICABILITY The present invention is suitable for a lighting fixture such as an emergency lighting fixture that is embedded and fixed in a mounted portion such as a ceiling.

An emergency lighting fixture characterized by thermally coupling an LED substrate and a power supply substrate has been proposed (for example, refer to Patent Document 1).
However, in the configuration described in Patent Document 1, since the LED substrate and the power supply substrate are thermally coupled, when either one is driving, it is not intended to the other non-driving substrate. There was a problem of giving heat.

Further, an emergency lighting fixture has been proposed in which two thermally separated spaces are provided in the fixture body, and a light source and a lighting circuit are housed in each space (for example, see Patent Document 2).
However, in the configuration described in Patent Document 2, since the light source and the circuit board are housed in one housing space, there is a problem that heat is applied to the circuit board when the light source is turned on.

In addition, an emergency lighting device that efficiently dissipates the heat generated by the LED and irradiates the heat for a predetermined time by bringing the heat dissipating unit having the plurality of heat dissipating fins into contact with the light source unit having the LED has been presented (for example, , Patent Document 3).
However, Patent Document 3 does not describe heat dissipation from the heat dissipation portion of the emergency lighting fixture to the outside of the fixture. When the heat radiating portion radiates heat to the inside of the device, it is considered that the ambient temperature of the LED rises, and the light flux of the LED is attenuated and the life thereof is shortened.

In addition, an emergency lighting fixture has been presented in which the lighting device is projected to the side of the fixture body to reduce the size of the fixture body, the diameter of the fixture installation hole, and the design portion. , Patent Document 3).
However, in the emergency lighting device described in Patent Document 3, the lighting device protruding to the outside of the main body of the device causes an increase in the space occupied by the device itself after installation, and it is necessary to consider adjacent construction materials and other devices. To be done.

In addition, an emergency lighting device has been proposed in which a battery is inserted from the battery insertion opening and the battery is attached to the battery mounting portion (for example, see Patent Document 4).
However, Patent Document 4 does not describe how to devise a guide used when inserting a battery into an emergency lighting fixture. Without devising a guide, there is a possibility that the connector connection part may not fit well, and there was a problem in the attachability/detachment of the battery.

In addition, the lighting device for the LED serving as the main light source is arranged outside the fixture, and the inspection switch and the monitor LED are provided separately from the LED substrate serving as the main light source, and the emergency lighting fixture is arranged next to the LED serving as the main light source. Is proposed (for example, see Patent Document 3).
However, in the configuration described in Patent Document 3, since the LED substrate and the monitor LED are provided on the same substrate, the monitor LED is unintentionally affected by the heat of the LED of the main light source. Further, since the LED serving as the main light source and the monitor LED are arranged on the same substrate, there is a problem that even if the arrangement of the monitor LED is desired to be changed, it cannot be easily changed.

There is also proposed an emergency lighting fixture in which a monitor LED is mounted on the same substrate as the LED serving as the main light source, and an inspection switch is provided on another substrate (for example, refer to Patent Document 5).
In the configuration described in Patent Document 5, the monitor LED and the inspection switch are provided separately from the substrate on which the LED serving as the main light source is arranged, so there is a degree of freedom in arrangement, but the lighting device is arranged outside the fixture. Therefore, there is a problem in that there are restrictions on the installation work of the equipment.

JP, 2014-032868, A (refer paragraphs "0064"-"0066".) JP, 2008-262770, A Japanese Unexamined Patent Application Publication No. 2012-084324 (see paragraph “0031”).

In the event of a power failure such as a fire, the emergency lighting equipment has a structure and installation standard established by the Building Standards Act so that a certain level of illuminance can be secured and the evacuation can be performed quickly in the event of a power failure.

The emergency lighting fixture that lights up in the event of a power failure such as a fire must ensure a predetermined brightness (floor illuminance 1 lx at high temperature) even in an emergency such as a fire.

In recent years, LEDs that have become widespread as light sources have a decrease in the luminous flux emitted as the temperature rises. Therefore, heat dissipation of the LED has become an important issue.

In addition, the special type of emergency lighting equipment equipped with only the emergency light source is in a state of charging the battery during normal use except when there is a power outage, and the light source is not turned on, so it has a strong presence as a lighting equipment. The smaller the size, the better, and there is a demand for reduction of equipment installation space and power saving.

In the embodiment of the present invention, it is desirable to efficiently dissipate the heat generated from the light source of the lighting fixture.

Further, in the embodiment of the present invention, it is desired to improve the assembling property of the lighting fixture.

Further, in the embodiment of the present invention, it is desired to reduce the size of the lighting fixture and improve the reliability.

Further, in the embodiment of the present invention, it is desired to improve the mountability of the battery unit in the small space of the lighting fixture.

Moreover, in the embodiment of the present invention, it is desired to provide an inspection unit that can be used in different lighting fixtures.

The lighting fixture of this invention is
Body,
A frame with a convex portion protruding on the back surface,
It is characterized in that it is provided with a frame mounting member which is inserted into the convex portion from the back side of the frame and is attached thereto, and the frame is detachably attached to the main body.

***Description of the structure and assembly of the light source unit 20***
The light source 26 is mounted in a recess at the center of the surface of the socket 24.
The socket 24 has a structure in which the light source 26 is sandwiched between the lens 24 and the lens 21, and power is supplied to the light source 26 by a connection terminal incorporated in the socket 24.
A connector 243 is attached to the tip of the electric wire 242 connected to the power supply terminal of the socket 24. The connector 243 is fixed to the connector fixing hole 272 of the light source mounting portion 27 to prevent tension from being applied to the power supply terminal of the socket 24.

The socket 24 is made of a material such as ceramics or resin.
Since the heat generated from the light source 26 is conducted to the light source mounting portion 27 via the socket 24, the material of the socket 24 is preferably a material having high thermal conductivity.
Further, between the light source mounting portion 27 and the socket 24, a heat radiation sheet or grease for reducing contact thermal resistance may be applied.

The lens 21 is arranged on the light emitting surface side of the socket 24.
In order to fix the positions of the lens 21 and the socket 24, the socket 24 and the lens 21 are provided with a positioning mechanism at positions facing each other.
Specifically, as shown in FIG. 8, the lens 21 is provided with a recessed concave portion 211 on the surface in contact with the socket 24, and the socket 24 has a protrusion-shaped convex portion at a position corresponding to the recessed portion of the lens 21. The part 241 is provided.
In FIG. 8, the concave portion 211 of the lens 21 and the convex portion 241 of the socket 24 are provided at three places, but the number may be changed appropriately according to the shape. The lens 21 may be provided with a convex portion and the socket 24 may be provided with a concave portion.

The lens 21 has a shape corresponding to a desired light distribution, and in the present embodiment, the lens 21 has a hemispherical shape or a dome shape protruding from the frame 29. The shape of the lens 21 may be changed appropriately according to the light distribution.
Further, the lens 21 does not have to protrude from the frame 29.
The lens 21 is preferably made of noncombustible glass, but may be made of transparent resin such as polycarbonate or acrylic, or silicon.
When used as an emergency lighting fixture, it is necessary to make the outer casing of the device noncombustible. Therefore, when the lens 21 is made of a material other than glass, it is necessary to cover the outer casing of the lens 21 with a glass cover.

The lens 21 in the present embodiment has a hemispherical or dome-like shape protruding from the lens hole 295 of the frame 29, and light is emitted from the protruding lens surface. At that time, if the inspection switch 62 projects from the frame 29, the emitted light may hit the inspection switch 62 and the desired light distribution may not be obtained.
The emergency lighting fixtures installed on the low ceiling with a height of 2 to 3 m have a light distribution with a peak light intensity at a shallow angle (60°). May be blocked.
Therefore, it is necessary to arrange the lens 21 and the inspection switch 62 in consideration of the direction (angle) emitted from the lens 21.
In this embodiment, the lens 21 is projected in a hemispherical shape or a dome shape so that the emitted light does not hit the inspection switch 62.
Further, a convex projecting portion 291 is provided around the lens hole 295 of the frame 29, and the lens 21 is arranged in the light emitting direction. In this way, the positions of the lens 21 and the inspection switch 62 in the vertical direction are displaced so that the light distribution is not affected.

The lens 21 has a hemispherical shape or a dome shape, and a collar portion 212 is provided on the outer peripheral portion of the lens 21. A ring-shaped packing 22 is attached to the flange portion 212, and when it comes into contact with other members, it is possible to prevent the lens 21 from being damaged by an impact. The packing 22 is made of, for example, silicon.

The frame mounting member 25 has a function of fixing the frame 29 and the light source mounting portion 27 and a function of fixing the light source unit 20 and the main body 10.

The light source unit 20 is fixed to the main body 10 using the mounting plate portion 253 of the frame mounting bracket 25.
The shape of the mounting plate portion 253 of the frame mounting member 25 is such that the width becomes narrower toward the tip end according to the shape of the main body 10. As shown in FIG. 10, W1>W2.
The fixing of the main body 10 and the frame 29 requires a holding force above a certain level. Therefore, a certain width is required to hold the frame mounting metal fitting 25 by utilizing its elasticity. On the other hand, since the main body 10 has a cylindrical shape and a circular cross section, and the frame mounting bracket 25 has a linear cross-sectional shape, when the mounting plate portion 253 has a width of a certain value or more, both ends of the mounting plate portion 253 are main bodies. 10 interferes with the light source mounting holes 124.
Further, since the main body 10 has a cylindrical shape, if the width of the mounting plate portion 253 of the frame mounting bracket 25 is large, the spring must be bent by a large amount for mounting.
Therefore, in order to prevent the interference with the main body 10 while maintaining the holding force, the interference does not occur by making the width of the mounting plate portion 253 at the tip of the frame mounting metal fitting 25 conforming to the shape of the main body 10 and narrowing toward the tip. It is possible to secure the holding power even in the state.

The light source mounting portion 27 is fixed to the frame 29 by the fixing plate portion 251 of the frame mounting bracket 25.

The teeth on both ends of the three-pronged portion 2511 are present on both sides of the bridge insertion hole 273. The teeth at both ends of the three-pronged portion 2511 have a bent portion 256 that is bent in a V shape on the side where the light source mounting portion 27 is located with respect to the central tooth. Since the bent portion 256 presses the thin portion 275 against the frame 29, it has a function of bringing the frame 29 and the light source mounting portion 27 into close contact with each other.
As shown in FIG. 12, the central tooth of the trifurcation 2511 is inserted under the bridge 293. When the insertion of the center tooth of the three-pronged portion 2511 into the bridge 293 is completed, the cut-and-raised part 255 is caught by the outer wall of the bridge insertion hole, and the frame mounting member 25 cannot be removed. After fixing the frame 29 to the light source mounting portion 27, the cut-and-raised parts 255 prevent the frame mounting bracket 25 from coming off.

As described above, the frame mounting member 25 has a function of bringing the frame 29 and the light source mounting portion 27 into close contact with each other. Further, the frame mounting member 25 has a function of bringing the lens 21 into close contact with the frame 29 and the socket 24 because the frame 29 and the light source mounting portion 27 are brought into close contact with each other.

Here, a method of assembling the light source unit 20 will be described with reference to the exploded perspective view of FIG.

Next, the connector 243 is inserted into the connector fixing hole 272, and the connector 243 is fixed to the light source mounting portion 27.

Next, the collar 22 of the lens 21 is covered with the packing 22.
Next, the concave portion 211 of the lens 21 is aligned with the convex portion 241 of the socket 24, and the lens 21 is aligned with the socket 24.
Next, the frame 29 is placed on the lens 21, and the lens 21 is sandwiched between the frame 29 and the socket 24. At this point, the lens 21 is in a state in which the movement in the horizontal direction is restricted by the positioning mechanism of the concave portion 211 and the convex portion 241 provided in the socket 24 and the protruding portion 291 of the frame 29.
When the frame 29 and the light source mounting portion 27 are aligned, as shown in FIG. 12, the bridge 293 provided in the frame 29 is aligned with the bridge insertion hole 273 provided in the thin portion 275 of the light source mounting portion 27. In this state, the bridge 293 of the frame 29 is higher than the thickness of the thin portion 275 of the light source mounting portion 27 by the height I, and the center tooth of the three-forked portion 2511 of the frame mounting bracket 25 is inserted when viewed from the side. It will be ready.

As shown by the arrow in (b) of FIG. 12, the frame attachment fitting 25 is inserted from the outer side in the radial direction of the frame 29 toward the central axis O, and the cut-and-raised portion 255 of the central tooth enters the bridge insertion hole 273. The frame mounting member 25 is fixed to the frame 29 in this state.
The frame mounting bracket 25 has a cut-and-raised part 255 in the center tooth, and the cut-and-raised part 255 is caught on the outer wall of the bridge insertion hole 273 when the insertion is completed. Therefore, even if a force is applied to the outside in the radial direction, the frame mounting bracket 25 should be removed. It can be prevented.
In this way, the light source mounting portion 27 and the frame 29 are fixed only by the frame mounting metal fitting 25, and no screws or adhesives are used.
With the above, the light source unit 20 is completed.

The heat dissipation of the light source unit 20 will be described.
The light source 26 is fixed to the front surface of the socket 24, and the back surface of the socket 24 is fixed in surface contact with the socket housing portion 271 of the light source mounting portion 27. It is transmitted to part 27.
The light source mounting portion 27 is fixed to the frame 29 using the frame mounting bracket 25, and the frame 29 and the light source mounting portion 27 are in close contact with each other, so that the frame 29 and the light source mounting portion 27 are thermally coupled. The light source mounting portion 27 is in surface contact with the back surface of the frame 29 in the direction of 360 degrees around the light source 26, and the frame 29 and the light source mounting portion 27 are thermally connected.

On the other hand, the light source unit 20 is arranged with respect to the lighting device 30 and the battery unit 40 via the heat shield space 72, as shown in the B-B cross-sectional view of FIG. 2. Since the heat shield space 72 exists between the light source mounting portion 27 and the lighting device 30, the light source unit 20 and the lighting device 30 are thermally separated. Further, since the heat shield space 72 exists between the light source mounting portion 27 and the battery unit 40, the light source unit 20 and the battery unit 40 are thermally separated.

Further, as shown in FIG. 13, the back surface of the light source mounting portion 27 is arranged with respect to the collar 13 via a space S1. The light source mounting portion 27 has an outer peripheral surface 277 along the inner peripheral surface of the main body 10.
The outer peripheral surface 277 of the light source mounting portion 27 is arranged with respect to the inner peripheral surface of the main body 10 via a space S2. Thus, since the space S1 and the space S2 exist between the light source mounting portion 27 and the main body 10, the light source unit 20 and the main body 10 are thermally separated.
Thus, most of the heat radiation to the outside air is performed from the frame 29.

***Explanation of the effect of the light source unit 20***

*** Explanation of the structure of the inspection unit 60 *****
The inspection unit 60 is built in the lighting fixture 100 and used for checking the lighting fixture 100.
When the lighting fixture 100 is an emergency lighting fixture, the lighting device 30 includes a circuit for switching between regular lighting and emergency lighting, and an inspection unit 60 is provided to perform a switching operation from the outside for the purpose of inspection.
The inspection unit 60 is externally attached to the outer surface of the corner of the device case 35, and is fitted by being laterally fitted.

As shown in FIG. 14, the inspection unit 60 includes a unit housing 61, an inspection switch 62, a coil spring 63, and an inspection board 64.
The unit housing 61 is a resin cover to which the inspection switch 62 and the inspection board 64 are attached. The unit housing 61 has a flat surface portion 614 arranged on the same plane as the side surface 353, and a cylindrical arc portion 615 having the same radius as the outer peripheral surface 354. The flat surface portion 614 and the tubular arc portion 615 are substantially orthogonal to each other.
The inspection switch 62 is a switch that is operated in the vertical direction by a person from outside the lighting equipment. In the figure, a pull rod type switch is shown.
The inspection switch 62 is laid out at a position where the inspection hole 294 and the cutout portion 276 are present in the vertical direction.
The coil spring 63 is a spring for always pulling the inspection switch 62 backward.
The inspection board 64 is a circuit board that inspects the lighting fixture 100 based on the operation of the inspection switch 62.
The inspection board 64 is arranged in parallel with the lighting circuit board 331 and the charging circuit board 332.
The inspection board 64 inspects whether the light source 26 is turned on by the power of the battery unit 40.
The inspection board 64 has a charge monitor 65 for confirming the charge state of the battery.
The unit housing 61 has a fixing mechanism 611.
The fixing mechanism 611 is a mechanism that fixes the inspection switch 62 and the inspection board 64 to an internal component of the lighting fixture 100 or an inner surface of the lighting fixture.
As the fixing mechanism 611, a lateral claw 612 and a lateral claw 613 formed so as to project in the lateral direction and fitted in the lateral direction are suitable.
The horizontal claw 612 is a claw formed to project laterally from the end of the flat surface portion 614 of the unit housing 61 toward the side surface 353.
The lateral claws 613 are claws formed to project laterally from the end of the cylindrical arc portion 615 of the unit housing 61 toward the outer peripheral surface 354.
The lateral claws 612 and 613 are claws formed in a direction orthogonal to each other in the lateral direction.
The unit housing 61 is fixed to the outer surface of the lighting device 30 by the horizontal claws 612 and 613 without using tools.
The unit housing 61 does not project from the same plane as the side surface 353. Further, it does not project from an arc surface having the same radius as the outer peripheral surface 354.

The fixing mechanism 611 includes a vertical movement limiting mechanism 67 that limits the vertical movement of the unit housing 61.
The vertical movement limiting mechanism 67 prevents the unit housing 61 from coming off in the vertical direction.
As the vertical movement limiting mechanism 67, it is preferable to use a protruding claw 671 that protrudes inward from the inner surface of the unit housing 61. The protruding claw 671 is caught by the protruding claw 324 protruding outward from the outer surface of the inspection unit mounting portion 351, and prevents the unit housing 61 from coming off in the vertical direction.

The inspection unit mounting portion 351 is formed by denting the corner of the device case 35, and the unit housing 61 has a cover shape that covers the dent of the inspection unit mounting portion 351. Together with the body 61, it has a cubic shape.

***Explanation of structure and assembly of inspection unit 60***
A method of assembling the inspection unit 60 will be described.
First, the coil spring 63 is set on the body of the inspection switch 62 and fitted into the unit housing 61.
The inspection switch 62 and the unit housing 61 are each provided with a boss and a standing wall for fixing the coil spring, so that the inspection switch 62 is always located in a state in which the inspection switch 62 is pushed inward in the instrument installation state.

Next, the inspection board 64 is fitted into the board claw provided on the unit housing 61. In this state, the inspection switch side connector 3371 of the inspection switch harness 337, which is taken out from the device case 35 of the lighting device 30, is attached to the inspection switch connector 66 of the inspection board 64.
After that, the unit housing 61 is attached to the inspection unit mounting portion 351 provided on the inspection switch side case 32. When the unit housing 61 is attached to the inspection unit mounting portion 351, the lateral claws 612 provided on the unit housing 61 are inserted into the lateral claw holes 323 provided on the side surface 353 of the inspection switch side case 32, and the lateral claws 613 are inserted. Is inserted into the lateral claw hole 323 provided on the outer peripheral surface 354 of the inspection switch side case 32.
The insertion direction is a horizontal direction orthogonal to the vertical direction in which the inspection switch 62 is operated. This is to prevent the unit casing 61 from coming off from the inspection switch side case 32 when the inspection switch 62 is operated.

On the other hand, if it is only hooked in the horizontal direction, it is not fixed in the vertical direction and easily comes off. Therefore, the protruding claw 671 is also provided and fixed in the vertical direction. That is, in order to limit the vertical movement, the unit housing 61 is attached to the device case 35 in the horizontal direction by using the movement in the horizontal direction with respect to the back wall surface of the protruding claw 324 of the inspection unit mounting portion 351. The projection claws 671 may be slid laterally on the wall surface of the projection claws 671 in the opening direction to hook the projection claws. In the vertical direction, the wall surface of the projecting claw 671 of the unit housing 61 in the opening direction is in contact with the wall surface of the projecting claw 324 of the inspection unit mounting portion 351 in the rear direction, so that the inspection unit 60 moves in the opening direction. I can't.

The inspection board 64 is provided with an inspection switch 62 and a charging monitor 65, and the charging monitor 65 can be checked from the frame 29 while the inspection unit 60 is assembled to the device case 35 so that the light emission state of the charging monitor 65 can be confirmed. Is laid out at a position where the inspection hole 294 and the cutout portion 276 exist in the vertical direction. The charging monitor 65 uses, for example, a green LED. Note that the number of monitors may be two or more instead of one.

Although the inspection switch 62 is fixed on the lighting circuit board 331 side, the lighting circuit board 331 and the inspection board 64 are arranged in parallel, and the lighting circuit board 331 and the inspection board 64 are on the board surface. It is arranged so that it overlaps with the vertical projection plane. Therefore, it is desirable to use, as the circuit components of the lighting circuit board 331, a component whose height is as low as possible in the place where the inspection board 64 is arranged.
By doing so, the three circuit boards can be arranged in parallel, and the boards can be efficiently arranged even in a small space of the main body 10.

***Explanation of the effect of inspection unit 60***
According to the present embodiment, since the inspection unit 60 exists separately from the lighting device 30, the degree of freedom in the arrangement position of the inspection unit 60 increases, and the same inspection unit 60 can be used in various lighting fixtures. ..

Embodiment 2.
In the second embodiment, different points from the first embodiment will be described.
***Explanation of structure and structure***
Some emergency lighting devices have different illuminance ranges, and some have different lighting times depending on the battery unit.
The battery unit also needs to increase its capacity according to the output of the light source 26.

When the illuminance range is different, it can be dealt with by changing the output of the light source 26 and the shape of the lens 21.
Further, when the emergency lighting time is different, it is possible to deal with it by changing the capacity of the battery unit 40.

The battery unit 40 according to the first embodiment is configured to use five AA cells (AA size), but when the capacity is to be increased, the battery unit 40 is moved upward or downward inside the main body 10 or in the lateral direction. It is possible to deal with the problem by using an expanded battery unit 40 with a C cell as the battery or increasing the number of cells.

When the capacity of the battery unit 40 is increased, it is possible to deal with it by changing the size or the number of cells. At that time, the shape of the battery unit 40 needs to be changed, but without changing the fitting structure M with the lighting device 30 using the guide rib 46, the outer shape of the case of the battery unit 40 is enlarged. ..
As a method of changing the shape of the battery unit 40, it is considered that the battery unit 40 is enlarged in the instrument height direction as shown in FIGS. 19 and 20, and the instrument diameter is enlarged as shown in FIGS. 21 and 22. ..
When the device is expanded in the height direction, it can be dealt with by changing the height of the device while keeping the diameter of the device the same.

On the other hand, when the instrument diameter is increased, it is possible to deal with it by changing only the instrument outline without changing the instrument height.
These are appropriately selected according to the form of the device.

In the appliance embedded in the ceiling shown in FIG. 20, since the appliance height does not affect the design surface, it is desirable to change the appliance height without changing the appliance diameter.
In the battery unit 40 shown in FIG. 19, a part of the battery unit is arranged in the opening direction in which the opening 101 is provided from the lighting device 30.
The battery unit 40 shown in FIG. 19 has the same fitting structure M as that of the first embodiment, and has an enlarged portion N in the vertical direction.
In the fixture embedded in the ceiling shown in FIG. 20, the enlarged portion N of the battery unit 40 is arranged on the side of the lighting device 30 where the light source unit 20 is located. The enlarged portion N of the battery unit 40 is between the lighting device 30 and the light source unit 20, and the fixture mounting work spaces 70 are secured on both sides of the lighting device 30 as in the first embodiment. It does not hinder the movement of the metal fitting 14.
In the fixture embedded in the ceiling shown in FIG. 20, it is difficult to secure 10% or more of the height T of the lighting fixture 100 for the vertical length K3 of the heat shield space 72, but there is a gap of 5% or more. It is good to secure and insulate.

The battery unit 40 shown in FIG. 21 has a semi-cylindrical shape, has the same fitting structure M as that of the first embodiment in the center, and has an enlarged portion N in the radial direction. The outer radius of the battery unit 40 is the same as the inner radius of the enlarged main body 10.
In the instrument directly attached to the ceiling shown in FIG. 22, when the instrument height is changed, the amount of protrusion from the ceiling surface increases, so it is desirable to increase the instrument diameter while keeping the height the same.

In the instrument directly attached to the ceiling shown in FIG. 22, the main body 10 has a pair of instrument attachment holes 115 in the work space arrangement direction X.
The lighting device 30 is fixed to the main body 10 so as to traverse a straight line connecting the pair of fixture mounting holes 115 and not block the fixture mounting holes 115.
The fixture directly attached to the ceiling will be fixed to the ceiling with a screw, but by laying out the lighting device 30 in the center of the main body 10, a fixture mounting work space 70 is formed at a symmetrical position from the center of the fixture, The device mounting hole 115 can be exposed in the opening direction. The instrument mounting hole 115 is formed in the work space arrangement direction X, similarly to the slit 123 of the first embodiment. That is, by forming the instrument mounting hole 115 in the depth direction of the instrument mounting work space 70 of the back plate 11, a screw fastening work space to the ceiling can be secured.

In the fixture directly attached to the ceiling shown in FIG. 22, since there is a space between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the main body 10, the left and right parts of the enlarged portion N of the battery unit 40 are turned on. It is arranged in a space between a part of the outer peripheral surface 354, which is the side surface having the short side of the device 30, and the inner peripheral surface of the main body 10.

Also in the appliance directly attached to the ceiling shown in FIG. 22, it is desirable that the power supply terminal block 50 is arranged at the center of the main body 10. This is because when drilling a hole in the ceiling, the hole is drilled in the center where the device is attached, and it becomes easy to attach the electric wire from the back of the ceiling to the power supply terminal block 50.

In the appliance directly attached to the ceiling shown in FIG. 22, the main body 10 is integrated with the frame 29 of the light source unit 20, and the main body 10 is exposed in the air.
