Description

The present invention relates to a lighting fixture.
The present invention is suitable for battery-powered luminaires and emergency luminaires.
The present invention is suitable for a lighting fixture such as an emergency lighting fixture that is embedded and fixedly arranged 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 presented (see, for example, 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 one of them is driven, it is not intended for the other non-driven substrate. There was a problem of giving heat.

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

Further, an emergency lighting fixture is presented in which the heat generated by the LED is efficiently radiated and irradiated for a predetermined time by contacting the heat radiating portion provided with a plurality of heat radiating fins with the light source portion provided with the LED (for example). , Patent Document 3).
However, Patent Document 3 does not describe heat dissipation from the heat radiation portion of the emergency lighting fixture to the outside of the fixture. When the heat radiating part dissipates heat to the inside of the fixture, it is considered that the ambient temperature of the LED rises, and the luminous flux of the LED is attenuated and the life of the LED is shortened.

In addition, an emergency lighting fixture has been presented that makes it possible to reduce the size of the fixture body by projecting a lighting device to the side of the fixture body, to reduce the diameter of the fixture installation hole, and to reduce the size of the design part (for example). , Patent Document 3).
However, in the emergency lighting fixture described in Patent Document 3, the lighting device protruding to the outside of the fixture body increases the space occupied by the fixture after installation, and it is necessary to consider adjacent construction materials and other fixtures. Will be done.

Further, an emergency lighting fixture in which a battery is inserted through a battery insertion opening and the battery is attached to a battery mounting portion is presented (see, for example, Patent Document 4).
However, Patent Document 4 does not describe the device of the guide used when inserting the battery of the emergency lighting equipment. If the guide is not devised, the connector connection may not fit properly, and there is a problem in the detachability of the battery.

In addition, an LED lighting device that serves as the main light source is placed outside the fixture, and an inspection switch and monitor LED are provided separately from the LED substrate that serves as the main light source, and an emergency lighting fixture that is placed next to the LED that serves as the main light source. Is presented (see, for example, 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 as the main light source and the monitor LED are arranged on the same substrate, there is a problem that even when the arrangement of the monitor LED is desired to be changed, it cannot be easily changed.

Further, an emergency lighting fixture in which an LED for a monitor is mounted on the same substrate as an LED as a main light source and an inspection switch is used as a separate substrate has been proposed (see, for example, Patent Document 5).
In the configuration described in Patent Document 5, since 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, there is a degree of freedom in arrangement, but the lighting device is arranged outside the fixture. Therefore, there is a problem that the installation work of the equipment is restricted.

In the event of a power outage due to a fire or the like, the structure and installation standards of emergency lighting equipment are stipulated by the Building Standards Law so that a certain level of illuminance can be secured and evacuation can be carried out promptly.

An emergency lighting fixture that lights up in the event of a power outage in the event of a fire or the like must ensure a predetermined brightness (floor illuminance 1 lpx at high temperatures) even in an emergency such as a fire.

In recent years, LEDs that have become widespread as a light source have their luminous flux attenuated as the temperature rises. Therefore, it is an important issue to dissipate heat from the LED.

In addition, a dedicated type emergency lighting fixture equipped with only an emergency light source has a presence as a lighting fixture because the battery is charged and the light source is not lit during normal use other than during a power outage. Smaller ones are preferable, and there is a demand for reduction of equipment installation space and power saving.

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

Further, in the embodiment of the present invention, it is desired to improve the assemblability of the lighting equipment.

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

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

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

The luminaire 100 includes a main body 10, a light source unit 20, a lighting device 30, a battery unit 40, a power terminal block 50, and an inspection unit 60.
The lighting device 30, the battery unit 40, and the power terminal block 50 are internal parts housed in the lighting fixture 100.
The main body 10 has a cylindrical shape.
The main body 10 is made of a non-combustible material such as metal.
The main body 10 is attached to the ceiling by the fixture mounting portion 102. As the instrument mounting portion 102, the instrument mounting bracket 14 is suitable.
The light source unit 20 has a light source 26 and is attached so as to close the opening of the main body 10.
The lighting device 30 is arranged inside the main body 10 and supplies electric power to the light source 26.
The lighting device 30 functions as a control device for lighting the light source 26.
The battery unit 40 is arranged inside the main body 10, stores a storage battery, and supplies electric power to the lighting device 30.
The power terminal block 50 is arranged at the back of the main body 10 and connects an electric wire from an external commercial power source to supply electric power to the lighting device 30.
The inspection unit 60 inspects the lighting of the lighting fixture 100.

The main body 10 will be described with reference to FIG.
The main body 10 has a bottomed cylindrical shape having an opening 101 on one surface.
The main body 10 is a metal housing that houses the lighting device 30, the battery unit 40, and the power terminal block 50.
One of the main body 10 is opened by the opening 101, and the opening 101 is covered by the light source unit 20.

The main body 10 has a back plate 11, a side plate 12, a collar 13, and an instrument mounting bracket 14.
The back plate 11 is a metal circular plate that closes the back direction of the main body 10.
The side plate 12 is a metal cylindrical plate having a pipe shape.
The brim 13 is formed in the shape of an eave at the end of the opening 101 of the side plate 12, and has a donut shape.
The diameter of the collar 13 is larger than the diameter of the fixture insertion hole in the ceiling, and the collar 13 is attached to the edge of the fixture insertion hole in the ceiling. The lighting fixture 100 is fixed to the ceiling by sandwiching the ceiling plate from above and below between the collar 13 and the fixture mounting bracket 14.

The back plate 11 has a screw hole 111, a screw hole 112, and a terminal exposed hole 113.
The screw hole 111 is a hole through which the screw 19 for fixing the power terminal block 50 penetrates.
The screw holes 111 may be arranged only on the side plate 12 of the main body 10 or on the back plate 11 and the side plate 12 to fix the lighting device 30.
The screw hole 112 is a hole for fixing the screw 18 for fixing the lighting device 30.
The terminal exposure hole 113 is an opening that exposes the power supply terminal block 50.
The wire 114 is a wire that is fixed to the main body 10 or the back plate 11 of the main body 10 and connects the light source unit 20. When the wire 114 is fixed to the main body 10 instead of the back plate 11 of the main body 10, the fixing position of the wire 114 may be near the opening 101 of the side plate 12 of the main body 10.
The lighting device 30 and the light source 26 built in the main body 10 are electrically connected by the light source harness 336, but prevent tension from being applied to the light source harness 336 when the light source unit 20 is attached to and detached from the main body 10. Therefore, a wire 114 shorter than the light source harness 336 is attached to the frame 29 and the main body 10. As the wire 114, a string, a metal wire, or the like is used, and the wire 114 becomes a tension prevention wire.

The side plate 12 has a battery fixing metal fitting 121, a horizontal stopper 122, a slit 123, and a light source mounting hole 124 shown in the BB cross-sectional view of FIG.
The battery fixing bracket 121 is a V-shaped leaf spring, and is fixed to the inner peripheral surface of the side plate 12 in a state of being opened in a V-shape in the back direction. The battery unit 40 is fixed at the opening end opened in a V shape to prevent the battery unit 40 from falling in the opening direction.
The horizontal stopper piece 122 is a rectangular piece obtained by cutting a part of the side plate 12 into a rectangular shape in the lateral direction to form a screw hole and bending it inside the main body 10. The horizontal stopper piece 122 is used for screwing the lighting device 30 from the lateral direction.

The slit 123 is a linear opening formed in the vertical direction of the side plate 12.
Two slits 123 are formed so as to be elongated in the vertical direction of the side plate 12 and opposed to each other in the diametrical direction, and the instrument mounting bracket 14 is attached to each of the slits 123.
The instrument mounting bracket 14 is mounted in the work space arrangement direction X.
The fixture mounting bracket 14 is a bracket for mounting the lighting fixture 100 to the ceiling.
The instrument mounting bracket 14 is slidably mounted in the vertical direction with respect to the slit 123.
The fixture mounting bracket 14 slides the slit 123 vertically to the back surface of the ceiling to fix the lighting fixture 100 to the ceiling.
The light source mounting hole 124 is a rectangular opening formed near the opening direction of the side plate 12.
Two light source mounting holes 124 are formed so as to face each other in the diameter direction of the side plate 12, and the frame mounting bracket 25 of the light source unit 20 is mounted in the longitudinal direction Y of the lighting device.
The work space arrangement direction X and the lighting device longitudinal direction Y are orthogonal to each other.

As shown in the DD opening view of FIG. 2, the lighting device 30 has an oval shape when viewed from the vertical direction.
The long side L of the lighting device 30 is the same as the inner peripheral diameter of the main body 10.
Since the short side S of the lighting device 30 is shorter than the long side L, a pair of fixture mounting work spaces 70 are formed on both sides.
In the DD opening view of FIG. 2, the lighting device 30 has a dent space 74 for accommodating the battery unit 40 in the central portion of the right side surface, and the portion having the dent space 74 is shorter than the short side S. The width is W.
Therefore, on the right side of the lighting device 30, an appliance mounting work space 70 wider than the fixture mounting work space 70 on the left side is formed.
In the DD opening view of FIG. 2, the space length K1 in the radial direction of the fixture mounting work space 70 on the left side of the lighting device 30, the width W of the lighting device 30, and the diameter of the fixture mounting work space 70 on the right side of the lighting device 30. The ratio of the direction to the space length K2 is 2: 4: 4.
The reason why the instrument mounting work space 70 on the right side is wide is that it is used as a battery mounting space 71 for accommodating the battery unit 40.

As shown in the cross-sectional view taken along the line BB of FIG. 2, the light source unit 20 is attached via the heat blocking space 72 when viewed from the lateral direction.
In the cross-sectional view taken along the line BB of FIG. 2, the vertical length K3 of the heat blocking space 72 is 17% of the height T of the main body 10 of the lighting fixture 100, and is preferably 10% or more and 20% or less.

The lighting device 30 is composed of a case whose outer shell is made of resin.
The lighting device 30 has a storage space 73 for accommodating the power terminal block 50 in the back direction, facing the back plate 11. The storage space 73 is a recess recessed in the opening direction from the surface of the lighting device 30 in contact with the back plate 11.

As shown in the BB cross-sectional view of FIG. 2, the battery unit 40 is arranged in the battery mounting space 71 inside the main body 10 and supplies electric power to the light source 26.
The battery unit 40 is detachably mounted in the battery mounting space 71.
The battery mounting space 71 occupies a part of one fixture mounting work space 70 of the pair of fixture mounting work spaces 70.

The power terminal block 50 is fixed to the back plate 11 and exists in the back center of the main body 10.
One side of the power supply terminal block 50 is exposed from the terminal exposure hole 113, and an electric wire from an external power source is connected from the terminal exposure hole 113.
The power terminal block 50 has a terminal body 51 and a terminal mounting plate 52.
The terminal mounting plate 52 is a cover for fixing the terminal body 51 to the back plate 11 with screws 19.
The power terminal block 50 is housed in the storage space 73 of the lighting device 30 and does not project outward from the side surface 353 of the lighting device 30.

*** Explanation of the structure and assembly of the lighting fixture 100 ***
The main body 10 is attached to the ceiling using the fixture mounting bracket 14.
The fixture mounting bracket 14 is fitted in a slit 123 provided in the main body 10, and the main body 10 is fixed to the ceiling by installing the fixture on the ceiling and sliding the fixture mounting bracket 14 downward.
As a method of fixing the main body 10 to the ceiling, a method using a leaf spring may be used.

The lighting device 30 has a rectangular parallelepiped shape having a long side L, a short side S, and a height H.
The lighting device 30 is arranged so that the height H is in the vertical direction, and the long side L and the short side S can be seen from the opening 101.
The lighting device 30 is arranged across the center of the main body 10 when viewed from the opening 101.
The lighting device 30 is fixed so that the longitudinal direction of the lighting device 30 crosses the work space arrangement direction X.
That is, the work space arrangement direction X and the long side L of the lighting device 30 are orthogonal to each other, and the longitudinal direction Y of the lighting device 30 and the short side S of the lighting device 30 are orthogonal to each other.
A pair of fixture mounting work spaces 70 are formed between the side surface 353 having the long side L of the lighting device 30 and the inner peripheral surface of the main body 10. It is desirable to increase the instrument mounting work space 70 by setting the long side L >> short side S.
Since there is a pair of fixture mounting work spaces 70 in the work space arrangement direction X, the vertical movement of the fixture mounting bracket 14 that slides the slit 123 in the vertical direction is not hindered.
The outer peripheral surface 354 having the short side S is a curved surface having the same radius R as the inner peripheral surface of the main body 10, and the outer peripheral surface 354 is inscribed in the inner peripheral surface of the main body 10.
The lighting device 30 has a screw fixing portion 37 protruding from the side surface 353 at the back of the side surface 353.

The assembly method and the mounting method of the luminaire 100 will be described with reference to FIG.

The screw fixing portion 37 of the lighting device 30 is fixed to the back plate 11 with a screw 18 from the inside of the main body 10, but since the screw fixing portion 37 exists in the back of the fixture mounting work space 70, the screw 18 is screwed in. The work is easy.
At this point, the instrument mounting work space 70 is formed between the side surface 353 and the inner peripheral surface of the main body 10 in the work space arrangement direction X.
S6. An instrument mounting bracket 14 (not shown in FIG. 3) is attached to the slit 123 of the main body 10. Since the instrument mounting work space 70 exists around the slit 123 inside the main body 10, the instrument mounting bracket 14 can be easily mounted.
S7. The battery unit 40 is attached to the lighting device 30. The battery fixing bracket 121 on the inner peripheral surface of the main body 10 changes from a V-shape to an I-shape as the battery unit 40 is inserted, and returns to the V-shape after passing through the battery unit 40. In this way, the battery unit 40 is hooked on the battery fixing metal fitting 121 and fixed so that the battery unit 40 does not come off.
Do not make electrical connections to prevent over-discharging of the battery unit 40. Alternatively, the battery unit 40 may not be attached to the lighting device 30 and may be packaged separately.
S8. The light source unit 20 is attached to the wire 114. Further, the light source connector 3361 at the other end of the light source harness 336 is connected to the light source unit 20.

*** Explanation of the structure and assembly of the light source unit 20 ***
The light source 26 is mounted in a recess in 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 light source 26 and the lens 21, and power is supplied to the light source 26 by a connection terminal built 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, a heat radiating sheet or grease for reducing the contact thermal resistance may be applied between the light source mounting portion 27 and the socket 24.

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 positioning mechanisms at positions facing each other.
Specifically, as shown in FIG. 8, the lens 21 is provided with a recessed recess 211 on the surface in contact with the socket 24, and the socket 24 has a protrusion-shaped protrusion at a position corresponding to the recess of the lens 21. A portion 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 quantity may be appropriately changed 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 or dome-shaped lens 21 protruding from the frame 29. The shape of the lens 21 may be appropriately changed 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 non-combustible glass, but may be made of a transparent resin such as polycarbonate or acrylic, silicon, or the like.
When used as an emergency lighting fixture, the outer shell of the fixture needs to be a non-combustible material. Therefore, when the lens 21 is made of a material other than glass, it is necessary to cover the outer shell of the lens 21 with a glass cover.

The lens 21 in the present embodiment has a hemispherical or dome-shaped protrusion 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 protrudes from the frame 29, the emitted light hits the inspection switch 62, and a desired light distribution may not be obtained.
The emergency lighting fixtures mounted on a low ceiling with a height of 2 to 3 m have a light distribution with a peak of luminous intensity at a shallow angle (60 °), so the light is lit by the frame 29 and the pull rod type inspection switch 62. 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 the present embodiment, the lens 21 is projected in a hemispherical or dome shape so that the emitted light does not hit the inspection switch 62.
Further, a convex protrusion 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 shifted so that the light distribution is not affected.

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

The frame mounting bracket 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 by using the mounting plate portion 253 of the frame mounting bracket 25.
The shape of the mounting plate portion 253 of the frame mounting bracket 25 is such that the width becomes narrower toward the tip in accordance with the shape of the main body 10. As shown in FIG. 10, W1> W2.
Fixing the main body 10 and the frame 29 requires a holding force of a certain level or more. Therefore, a certain width is required when holding the frame mounting bracket 25 by utilizing the elasticity of the frame mounting bracket 25. On the other hand, since the main body 10 has a tubular shape and a circular cross section, and the cross-sectional shape of the frame mounting bracket 25 is straight, when the mounting plate portion 253 has a certain width or more, both ends of the mounting plate portion 253 become the main body. It interferes with the light source mounting hole 124 of 10.
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 flexed by that much for mounting.
Therefore, in order to maintain the holding force and not interfere with the main body 10, the mounting plate portion 253 at the tip of the frame mounting bracket 25 is narrowed toward the tip according to the shape of the main body 10 so as not to interfere. 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 fixing plate portion 251 that fixes the frame 29 and the light source mounting portion 27 is a three-pronged portion 2511 having a three-pronged shape, and three teeth are formed in the three-pronged portion 2511. The teeth at both ends of the three-pronged portion 2511 are present on both ends sides of the bridge insertion hole 273. The teeth at both ends of the three-pronged portion 2511 have a bent portion 256 bent in a V shape on the side where the light source mounting portion 27 is located rather than 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 three-pronged portion 2511 is inserted under the bridge 293. When the insertion of the central tooth of the three-pronged portion 2511 into the bridge 293 is completed, the cut-up 255 is caught on the outer wall of the bridge insertion hole, and the frame mounting bracket 25 cannot be removed. After fixing the light source mounting portion 27 to the frame 29, the cut-up 255 prevents the frame mounting bracket 25 from coming off.

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

Here, a method of assembling the light source unit 20 will be described with reference to the exploded perspective view of FIG.
The socket 24 is fixed to the socket storage portion 271 of the light source mounting portion 27 with screws 23.
Next, the connector 243 is inserted into the connector fixing hole 272 to fix the connector 243 to the light source mounting portion 27.

Next, the packing 22 is put on the brim 212 of the lens 21.
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 between 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 insertion hole 273 provided in the thin portion 275 of the light source mounting portion 27 is aligned with the bridge 293 provided in the frame 29. 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 central tooth of the three-pronged portion 2511 of the frame mounting bracket 25 is inserted when viewed from the side surface. It will be ready.

As shown by the arrow in FIG. 12B, the frame mounting bracket 25 is inserted from the radial outside of the frame 29 toward the central axis O, and the central tooth cut-out 255 is inserted into the bridge insertion hole 273. The frame mounting bracket 25 is fixed to the frame 29 in this state.
The frame mounting bracket 25 has a raised 255 on the central tooth, and when the insertion is completed, the raised 255 is caught on the outer wall of the bridge insertion hole 273, so that the frame mounting bracket 25 can be removed even when a force is applied to the outside in the radial direction. Can be prevented.
In this way, the light source mounting portion 27 and the frame 29 are fixed only by the frame mounting bracket 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.
Since 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 storage portion 271 of the light source mounting portion 27, the heat of the light source 26 is transferred to the socket 24 and the light source is mounted. It is transmitted to the part 27.
The light source mounting portion 27 is fixed to the frame 29 by 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 360-degree direction with the light source 26 as the center, and the frame 29 and the light source mounting portion 27 are thermally connected.

On the other hand, as shown in the cross-sectional view taken along the line BB in FIG. 2, the light source unit 20 is arranged with respect to the lighting device 30 and the battery unit 40 via the heat cutoff space 72. Since the heat blocking 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 from each other. Further, since the heat blocking 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 from each other.

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 the 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 the space S2. As described above, 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.
In this way, most of the heat radiated to the outside air is performed from the frame 29.

*** Explanation of the effect of the light source unit 20 ***
According to the present embodiment, since the frame 29, the light source mounting portion 27, the socket 24, and the light source 26 are thermally connected, the heat generated from the light source 26 is dissipated through the light source mounting portion 27 and the frame 29. Therefore, the heat of the light source 26 can be efficiently dissipated from the frame 29 to the atmosphere.

According to the present embodiment, the frame 29 is thermally connected to the light source mounting portion 27, and the heat generated from the light source 26 can be dissipated through the frame 29, so that the life of the light source is extended.

They are arranged so as to overlap each other on the vertical horizontal projection planes. Therefore, as for the circuit parts of the lighting circuit board 331, it is desirable to use parts having a height as low as possible at the place where the inspection board 64 is arranged.
By doing so, it becomes possible to arrange the three circuit boards in parallel, and the boards can be efficiently arranged even in the small space of the main body 10.

*** Explanation of the effect of the 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 is increased, and the same inspection unit 60 can be used in various lighting fixtures. ..

Embodiment 2.
In the second embodiment, the points different from the first embodiment will be described.
*** Explanation of structure and structure ***
Some emergency lighting fixtures have different illuminance ranges and some have different emergency 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 is possible to deal with it 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 of the first embodiment is configured to use five AA cells (AA size), but when the capacity is increased, the battery unit 40 is located inside the main body 10 in the upward or downward direction or in the lateral direction. In addition, an enlarged battery unit 40 can be used, and the battery can be changed to C cell or the number of cells can be increased.

When increasing the capacity of the battery unit 40, it is possible to change the size or number of cells. At that time, it is necessary to change the shape of the battery unit 40, but this can be dealt with by enlarging the outer shell of the case of the battery unit 40 without changing the fitting structure M using the guide rib 46 with the lighting device 30. ..
Regarding the method of changing the shape of the battery unit 40, it is conceivable that the shape of the battery unit 40 is expanded in the height direction of the appliance as shown in FIGS. 19 and 20, and the diameter of the appliance is expanded as shown in FIGS. 21 and 22. ..
When it expands in the height direction of the fixture, it can be dealt with by changing the height of the fixture while keeping the diameter of the fixture the same.

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

In the fixture embedded in the ceiling shown in FIG. 20, since the fixture height does not affect the design surface, it is desirable to change the fixture height without changing the fixture diameter.
In the battery unit 40 shown in FIG. 19, a part of the battery unit is arranged from the lighting device 30 in the opening direction where the opening 101 is located.
The battery unit 40 shown in FIG. 19 has the same fitting structure M as in the first embodiment, and has an enlarged portion N in the vertical direction.

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 blocking space 72, but a gap of 5% or more is provided. It is better 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 peripheral radius of the battery unit 40 is the same as the inner peripheral radius of the enlarged main body 10.
In the fixture directly attached to the ceiling shown in FIG. 22, if the height of the fixture is changed, the amount of protrusion from the ceiling surface increases. Therefore, it is desirable to increase the diameter of the fixture while keeping the height the same.

In the fixture directly attached to the ceiling shown in FIG. 22, the main body 10 has a pair of fixture mounting holes 115 in the work space arrangement direction X.
The lighting device 30 is fixed to the main body 10 so as to cross the linear direction connecting the pair of fixture mounting holes 115 and not to block the fixture mounting holes 115.
The fixtures that are directly attached to the ceiling are fixed to the ceiling with screws, but by laying out the lighting device 30 in the center of the main body 10, the fixture mounting work space 70 is formed at a position symmetrical to the center of the fixtures. The instrument 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 screwing work space to the ceiling can be secured.

In the fixture directly attached to the ceiling shown in FIG. 22, a space is created between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the main body 10, so that the left and right parts of the enlarged portion N of the battery unit 40 are lit.
