Description

The present invention relates to a lighting fixture.
The present invention is suitable for a lighting apparatus and an emergency lighting apparatus using a battery as a power source.
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 (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 not driven substrate. There was a problem of giving heat.

In addition, an emergency lighting fixture is provided 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 (see, for example, Patent Document 2).
However, in the configuration described in Patent Document 2, since the light source and the circuit board are stored in one storage 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 apparatus is proposed that efficiently dissipates the heat generated by the LED and makes it irradiate for a predetermined period of time when the heat radiating unit including a plurality of heat radiating fins contacts the light source unit including the LED (for example, And Patent Document 3).
However, Patent Document 3 does not describe the heat radiation from the heat radiation portion of the emergency lighting fixture to the outside of the fixture. When the heat radiating part is radiating heat to the inside of the appliance, it is considered that the ambient temperature of the LED rises, and the attenuation of the luminous flux of the LED and the shortening of the lifetime can be considered.

In addition, an emergency lighting fixture has been proposed that allows the lighting device to be protruded to the side of the fixture body to reduce the size of the fixture body, thereby reducing the diameter of the fixture installation hole and the design portion (for example, And Patent Document 3).
However, in the emergency lighting fixture described in Patent Document 3, the lighting device protruding outside the fixture body increases the fixture occupation space itself after installation, and it is necessary to consider adjacent construction materials and other fixtures. Is done.

Further, an emergency lighting fixture has been proposed in which a battery is inserted from a battery insertion opening and the battery is attached to a battery mounting portion (see, for example, Patent Document 4).
However, Patent Document 4 does not describe a guide device used when inserting a battery in an emergency lighting fixture. If the guide is not devised, there is a possibility that the connector connecting portion does not fit well, and there is a problem in battery detachability.

Also, an emergency lighting fixture in which an LED lighting device serving as a main light source is arranged outside the fixture, an inspection switch and a monitor LED are provided separately from the LED substrate serving as the main light source, and further arranged next to the LED serving as the main light source (For example, refer to 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 main light source LED. 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 when the arrangement of the monitor LED is desired to be changed, it cannot be easily changed.

In addition, an emergency lighting fixture has been proposed in which a monitor LED is mounted on the same substrate as the LED serving as a main light source, and an inspection switch is a separate substrate (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 appliance. Therefore, there has been a problem that there are restrictions on the installation of the appliance.

JP 2012-004050 A (see paragraph “0009”) JP 2012-185932 A (see paragraph “0010”) JP 2014-032868 A (see paragraphs “0064” to “0066”) JP 2008-262770 A Japanese Patent Laying-Open No. 2012-084324 (see paragraph “0031”)

  The structure and installation standards of emergency lighting fixtures are established by the Building Standards Act so that in the event of a power failure due to a fire or the like, a certain level of illuminance is ensured during a power failure and evacuation can be carried out quickly.

  Emergency lighting fixtures that are turned on in the event of a power outage in the event of a fire or the like must ensure a predetermined brightness (floor illuminance of 1 lx at high temperatures) even in the event of an emergency such as a fire.

  In recent years, LEDs that are widely used as light sources attenuate the emitted light flux as the temperature rises. Therefore, it is an important issue to dissipate the LED.

  In addition, dedicated emergency lighting fixtures that are equipped only with an emergency light source are in a state where the battery is charged during regular use other than during a power outage, and the light source is not lit. Smaller ones are preferable, and there is a demand for reduction in 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 fixture.

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

  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.

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

The present invention includes a cylindrical main body having an opening,
A battery unit disposed inside the body;
A lighting device that is disposed inside the main body and supplies power from the battery unit to the light source;
The battery unit has rail-shaped guide ribs,
The lighting device is
A mounting guide for sliding the guide rib;
The mounting guide is characterized in that a guide groove that is gradually narrowed toward the back of the main body is formed.

  According to the present invention, the battery unit can be mounted efficiently.

The power terminal block 50 is disposed in the back of the main body 10, connects an electric wire from an external commercial power source, and supplies power to the lighting device 30.
The inspection unit 60 inspects 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 casing that houses the lighting device 30, the battery unit 40, and the power terminal block 50.
One side 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 includes a back plate 11, a side plate 12, a flange 13, and an instrument mounting bracket 14.
The back plate 11 is a metal circular plate that covers the back direction of the main body 10.
The side plate 12 is a metal cylindrical plate having a pipe shape.
The ridge 13 is formed in the shape of a ridge 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 ceiling instrument insertion hole, and the collar 13 is attached to the edge of the ceiling instrument insertion hole. The lighting fixture 100 is fixed to the ceiling by the scissors 13 and the fixture mounting bracket 14 sandwiching the ceiling plate from above and below.

The back plate 11 has a screw hole 111, a screw hole 112, and a terminal exposure hole 113.
The screw hole 111 is a hole through which the screw 19 for fixing the power terminal block 50 passes.
The screw holes 111 may be provided 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 stopping the screw 18 that fixes the lighting device 30.
The terminal exposure hole 113 is an opening through which the power supply terminal block 50 is exposed.
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 fixing the wire 114 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 a light source harness 336, but when the light source unit 20 is attached to or detached from the main body 10, the light source harness 336 is prevented from being tensioned. 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 becomes a tension preventing wire.

The side plate 12 includes a battery fixing metal member 121, a lateral stopper piece 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 where the battery fixing bracket 121 is opened in a V shape in the depth direction. The battery unit 40 is fixed at the opening end opened in a V shape, and the battery unit 40 is prevented from dropping in the opening direction.
The lateral 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 the inside of the main body 10. The lateral 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 in the longitudinal direction of the side plate 12 so as to be opposed to each other in the diametrical direction, and each of the slits 123 is attached to the appliance mounting bracket 14.
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 attached to the slit 123 so as to be slidable in the vertical direction.

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 facing the diameter direction of the side plate 12, and the frame mounting bracket 25 of the light source unit 20 is mounted in the lighting device longitudinal direction Y.
The working 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 appliance 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 that houses the battery unit 40 in the center portion on the right side surface, and the portion with 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, a tool mounting work space 70 wider than the left tool mounting work space 70 is formed.
In the DD opening view of FIG. 2, the space length K1 in the diameter direction of the appliance 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 with the direction space length K2 is 2 to 4 to 4.
The reason why the right instrument mounting work space 70 is large is that it is used as a battery mounting space 71 for storing the battery unit 40.

As shown in the BB cross-sectional view of FIG. 2, the light source unit 20 is attached via a heat blocking space 72 when viewed from the lateral direction.
In the BB cross-sectional view of FIG. 2, the vertical length K3 of the heat shield 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 configured by a resin case.
The lighting device 30 has a storage space 73 that stores the power terminal block 50 facing the back plate 11 in the back direction. The storage space 73 is a recess that is recessed in the opening direction from the surface that contacts the back plate 11 of the lighting device 30.

As shown in the BB cross-sectional view of FIG. 2, the battery unit 40 is disposed in the battery mounting space 71 inside the main body 10 and supplies power to the light source 26.
The battery unit 40 is detachably mounted in the battery mounting space 71.
The battery attachment space 71 occupies a part of one appliance attachment work space 70 of the pair of appliance attachment 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 surface of the power terminal block 50 is exposed from the terminal exposure hole 113, and an electric wire from an external power source is connected through the terminal exposure hole 113.
The power supply terminal block 50 includes 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 stored in the storage space 73 of the lighting device 30 and does not protrude 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 an appliance mounting bracket 14.
The instrument 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 instrument on the ceiling and sliding the instrument 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 such that the height H is in the vertical direction, and the long side L and the short side S are seen from the opening 101.
The lighting device 30 is disposed 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 working space arrangement direction X and the long side L of the lighting device 30 are orthogonal to each other, and the lighting device longitudinal direction Y and the short side S of the lighting device 30 are orthogonal to each other.
A pair of appliance mounting work spaces 70 is 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. As long side L >> short side S, it is desirable to enlarge instrument mounting work space 70.
Since there is a pair of instrument mounting work spaces 70 in the work space arrangement direction X, the vertical movement of the instrument 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 includes a screw fixing portion 37 protruding from the side surface 353 behind the side surface 353.

The assembly method and attachment method of the lighting fixture 100 will be described with reference to FIG.
S1. The terminal body 51 is attached to the terminal attachment plate 52.
S2. The terminal body 51 and the lighting device 30 are connected by a terminal block harness 54. Further, one end of the light source harness 336 is connected to the lighting device 30.
S3. The terminal attachment plate 52 is attached to the lighting device 30. At this time, the power terminal block 50 is in a state of being stored in the storage space 73 of the lighting device 30.
S4. The lighting device 30 is inserted in the back direction from the opening 101, and the lighting device 30 is accommodated in the main body 10. At this time, the power terminal block 50 is stored in the main body 10 together with the lighting device 30 while being stored in the storage space 73 of the lighting device 30.
S5. The screw 19 is screwed into the screw hole 53 from the screw hole 111 to fasten the power terminal block 50 to the back plate 11. The power terminal block 50 is fixed to the center of the back plate 11 of the main body 10 by exposing one surface of the terminal main body 51 from the terminal exposure hole 113.
In addition, the lateral stopper piece 122 of the main body 10 and the screw boss 325 of the lighting device 30 are fastened with the screw 191. Further, the screw 18 is screwed into the screw hole 112 of the back plate 11 of the main body 10 to fix the screw fixing portion 37 of the lighting device 30 to the main body 10.
The lighting device 30 is fixed to the main body 10 such that the long side L is in the lighting device longitudinal direction Y and the short side S is in the work space arrangement direction X.
The screw fixing portion 37 of the lighting device 30 is fixed to the back plate 11 with the screw 18 from the inside of the main body 10. However, since the screw fixing portion 37 exists in the back of the instrument mounting work space 70, the screw 18 is screwed. Work is easy.
At this time, an instrument mounting work space 70 is formed in the work space arrangement direction X between the side surface 353 and the inner peripheral surface of the main body 10.
S6. The fixture 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 mounting work of the tool mounting bracket 14 is easy.
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 bracket 121 and fixed so that the battery unit 40 does not fall out.
In order to prevent overdischarge of the battery unit 40, electrical connection is avoided. Alternatively, the battery unit 40 may be separately packaged without being attached to the lighting device 30.
S8. The light source unit 20 is attached to the wire 114. The light source connector 3361 at the other end of the light source harness 336 is connected to the light source unit 20.
S9. The light source unit 20 is attached to the main body 10 by fitting the frame mounting bracket 25 into the light source mounting hole 124.

Next, the field work of attaching the lighting fixture 100 to the ceiling will be described.
First, the light source unit 20 is removed from the main body 10, and the light source unit 20 is removed from the wire 114. When the battery unit 40 is inside the main body 10, the battery unit 40 is removed from the main body 10. The battery unit 40 can be removed by manually pushing the battery fixing bracket 121 on the inner peripheral surface of the main body 10 so as to change from a V shape to an I shape.
Next, an electric wire behind the ceiling is connected to the power terminal block 50. The electric wire is inserted into a terminal on one surface of the terminal main body 51 exposed from the terminal exposure hole 113.
Next, the main body 10 is inserted into the instrument insertion hole in the ceiling, and a hand is put into the instrument mounting work space 70, and the instrument mounting bracket 14 is moved in the opening direction with the opening 110 to fix the main body 10 to the ceiling.
Next, the battery unit 40 is inserted from the opening 101 into one instrument mounting work space 70, that is, the depth direction of the battery mounting space 71.
Next, the light source unit 20 is attached to the wire 114, the frame mounting bracket 25 is fitted into the light source attachment hole 124, and the light source unit 20 is attached to the main body 10.

*** Explanation of effects of lighting fixture 100 ***
According to the present embodiment, the lighting device 30 is arranged in the center when viewed from the projection surface in the back direction from the opening of the main body 10, and work required for fixing the lighting apparatus 100 to a construction material such as a ceiling. Space can be secured. In other words, the appliance mounting work space 70 can be secured by the shape and arrangement of the lighting device 30.
According to the present embodiment, since the fixture mounting work space 70 exists inside the main body 10, the mounting workability of the lighting fixture 100 is improved, and the lighting fixture 100 can be assembled efficiently.

  According to the present embodiment, construction work of the lighting fixture 100 can be performed without using a tool at a site where the lighting fixture 100 is attached to the ceiling.

*** Explanation of structure and assembly of 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 lens 21 and supplies power to the light source 26 through 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, thereby preventing tension on the power supply terminal of the socket 24.

The socket 24 is made of a material such as ceramic or resin.
Since the heat generated from the light source 26 is conducted to the light source mounting portion 27 through the socket 24, the material of the socket 24 is preferably a material having high thermal conductivity.
Further, a heat radiation 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 disposed on the light emitting surface side of the socket 24.
In order to fix the position of the lens 21 and the socket 24, a positioning mechanism is provided at a position facing the socket 24 and the lens 21, respectively.
Specifically, as shown in FIG. 8, the lens 21 is provided with a concave recess 211 on the surface in contact with the socket 24. 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 in three places, but the quantity may be changed as appropriate 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. 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 may not 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 made of 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 shape that protrudes from the lens hole 295 of the frame 29 into a hemispherical shape or a dome shape, and light is emitted from the protruding lens surface. At this time, if the inspection switch 62 protrudes from the frame 29, the emitted light may hit the inspection switch 62 and a desired light distribution may not be obtained.
The emergency lighting fixture attached to a low ceiling of 2 to 3 m has a light distribution with a light intensity peak 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 the present 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 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 vertical positions of the lens 21 and the inspection switch 62 are shifted so that the light distribution is not affected.

  The lens 21 has a hemispherical or dome shape, and a collar portion 212 is provided on the outer periphery of the lens 21. The ring-shaped packing 22 is attached to the collar portion 212, and the lens 21 can be prevented from being damaged by an impact when coming 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 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 of the main body 10 and the frame 29 requires a certain holding force. Therefore, when holding using the elasticity of the frame mounting bracket 25, a certain width is required. On the other hand, the main body 10 is cylindrical and has a circular cross section, and the cross-sectional shape of the frame mounting bracket 25 is a straight line. 10 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 corresponding amount.
Therefore, in order not to interfere with the main body 10 while maintaining the holding force, the mounting plate portion 253 at the front end of the frame mounting bracket 25 is matched to the shape of the main body 10 so that the width decreases toward the front end, thereby preventing interference. Even in the state, it is possible to ensure the holding force.

The light source mounting portion 27 is fixed to the frame 29 by the fixing plate portion 251 of the frame mounting bracket 25.
As shown in FIG. 11, the frame 29 is provided with a bridge 293 for fixing the frame mounting bracket 25, and the light source mounting portion 27 has a bridge insertion hole at a position corresponding to the bridge 293 provided on the frame 29. 273 is provided.

Teeth at both ends of the trifurcated portion 2511 are present at both ends of the bridge insertion hole 273. The teeth at both ends of the trifurcated portion 2511 have a bent portion 256 bent into a V shape on the side where the light source mounting portion 27 is located, rather than the central tooth. The bent portion 256 presses the thin portion 275 against the frame 29, and thus has a function of bringing the frame 29 and the light source attachment portion 27 into close contact with each other.
As shown in FIG. 12, the center tooth of the trifurcated portion 2511 is inserted under the bridge 293. When the insertion of the tooth at the center of the three-pronged portion 2511 into the bridge 293 is completed, the cut-and-raised 255 is caught by 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 being removed.

  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. The frame mounting bracket 25 has a function of bringing the lens 21 into close contact with the socket 24 because the frame 29 and the light source mounting portion 27 are brought into close contact with each other.

Here, the assembly method of the light source unit 20 is demonstrated using the exploded perspective view of FIG.
The socket 24 is fixed to the socket housing portion 271 of the light source mounting portion 27 with the screw 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 collar portion 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 time, 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 aligning the frame 29 and the light source mounting portion 27, 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 a 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. It will be ready.

As shown by the arrow in FIG. 12 (b), the frame mounting bracket 25 is inserted from the radially outer side of the frame 29 toward the central axis O, and the central tooth cut and raised 255 enters the bridge insertion hole 273. In this state, the frame mounting bracket 25 is fixed to the frame 29.
The frame mounting bracket 25 has a cut-and-raised 255 at the center tooth, and when the insertion is completed, the cut-and-raised 255 is caught by the outer wall of the bridge insertion hole 273. Can be prevented.
Thus, the light source mounting portion 27 and the frame 29 are fixed only by the frame mounting bracket 25 and do not use screws or adhesives.
Thus, the light source unit 20 is completed.

The heat radiation 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 housing portion 271 of the light source mounting portion 27, the heat of the light source 26 is transmitted to the socket 24 and is attached to the light source. 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 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, the light source unit 20 is arranged with respect to the lighting device 30 and the battery unit 40 via the heat blocking space 72 as shown in the cross-sectional view along the line BB in FIG. 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. 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.

Further, as shown in FIG. 13, the back surface of the light source mounting portion 27 is disposed with respect to the flange 13 via a space S <b> 1. 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 disposed with respect to the inner peripheral surface of the main body 10 via the 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 effects of 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 radiated through the light source mounting portion 27 and the frame 29. Thus, the heat of the light source 26 can be efficiently radiated from the frame 29 to the atmosphere.

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

*** Explanation of structure and assembly of battery unit ***

A battery unit 40 is connected to the lighting device 30.
The battery unit 40 is for lighting the light source 26 in an emergency.
The battery unit 40 is charged from the lighting device 30 when power is supplied from the commercial power source, and supplies power to the lighting device 30 when the commercial power source fails.
As the charging method of the battery unit 40, trickle charging is desirable in order to compensate for the self-discharge of the battery unit 40 and always make it a fully charged state.

  The battery attachment portion 36 of the lighting device 30 is provided from the side surface 353 toward the appliance attachment work space 70. Thus, the battery mounting space 71 is formed in one of the pair of appliance mounting work spaces 70. The battery mounting space 71 is provided on the side where the charging circuit board 332 of the lighting device 30 is provided, and is disposed on the side opposite to the inspection unit 60.

  The battery unit 40 is inserted into the main body 10 after the main body 10 is fixed to the ceiling, and is connected and fixed to the lighting device 30. At this time, the lighting device 30 and the battery unit 40 are fitted to the battery side connector 3351 fixed to the lighting device 30 and the battery connector 45 of the battery unit 40, and to the battery fixing bracket 121 installed in the main body 10. It is fixed to the battery mounting portion 36 by fitting.

  Since the battery unit 40 is connected after the main body 10 is fixed to the ceiling, the battery unit 40 is placed at a position overlapping with the appliance mounting work space 70 secured as a space for operating the appliance mounting bracket 14 on the vertical projection plane. A unit 40 can be arranged.

In addition, it is desirable that the charging circuit board 332 of the lighting device 30 is arranged in consideration of the insertion position of the battery unit 40. That is, it is desirable that the tall circuit components of the charging circuit board 332 be laid out avoiding the arrangement of the battery unit 40.
As shown in FIG. 17, the side surface 353 of the battery-side case 31 has a recessed space 74 that is recessed from the side surface 353, and has a structure in which the protruding portion 47 is fitted. The recessed space 74 is in the central portion of the side surface 353.
Thus, when the insertion position of the battery unit 40 is the central portion of the charging circuit board 332, the tall circuit components of the charging circuit board 332 are not arranged in the central portion of the charging circuit board 332 but are arranged on both sides. It is good.

The fitting between the fitting structure M of the battery unit 40 and the battery mounting portion 36 of the lighting device 30 will be described.
As shown in FIG. 17, the battery unit 40 is inserted into the battery mounting portion 36 of the lighting device 30 while sliding in the back direction.
The battery unit 40 is provided with a guide rib 46 for sliding, and the lighting device 30 at a position corresponding to the guide rib 46 is provided with a mounting guide 314.

The lighting device 30 is installed in the main body 10, and a clearance is provided between the inner peripheral surface of the main body 10 and the outer peripheral surface of the device case 35 of the lighting device 30. When there is a space between the battery guide of the lighting device 30 and the main body 10, the guide rib 46 of the battery unit 40 may not be inserted at a predetermined position. That is, there is a possibility that the guide rib 46 fits in the space between the mounting guide 314 of the lighting device 30 and the main body 10. Therefore, the shape of the mounting guide 314 of the lighting device 30 is made into a trumpet shape with the battery insertion side widened, and the guide rib 46 of the battery unit 40 is drawn in so that the battery is inserted at an unintended position. Can be prevented.
In addition, since the rib taper portion 461 is provided, the guide rib 46 can be smoothly inserted into the mounting guide 314.
The mounting guide 314 becomes narrower as it goes in the insertion direction, suppressing rattling as the battery unit 40 is inserted, and eliminating rattling when the battery unit 40 is completely inserted. .

The lighting device 30 of the present embodiment has one mounting guide 314 on the left and right, and the right mounting guide 314 and the left mounting guide 314 are displaced in the vertical direction, that is, in the gravity direction. This is to secure a space for fixing the battery connector 45 to the lighting device 30 by making the position of the connector installation surface 318 in the height direction lower than the height H of the lighting device 30. When the positions of the left and right mounting guides 314 are shifted in the vertical direction, the battery unit 40 may be tilted left and right while the battery unit 40 is being inserted. Therefore, by providing a slide wall 316 serving as a vertical guide wall at a place other than the trumpet-shaped mounting guide 314, the battery unit 40 can be inserted straight into a predetermined position evenly on the left and right.
The battery connector 45 and the battery side connector 3351 are automatically connected when the battery unit 40 is inserted straight.

The battery unit 40 can be removed by pressing the battery fixing bracket 121 against the inner peripheral surface of the main body 10 while pushing the battery unit 40 in the back direction and removing the fixing with the battery fixing bracket 121. Since the battery unit 40 is hooked by the battery fixing bracket 121, the battery unit 40 can be removed without using a tool by removing the hook of the battery fixing bracket 121.
A knob 43 is provided on the lower surface of the battery unit 40 in order to facilitate removal when the battery unit 40 is removed. In order to improve operability, the knob 43 is preferably provided with anti-slip ribs, grooves, holes and the like.
When the battery case 42 of the battery unit 40 is configured to be easily grasped, the knob 43 may not be provided.

Since the knob 43 and the electric wire storage part 421 provided in the battery unit 40 are in an interference position with the light source attachment part 27 attached to the frame 29, it is necessary to avoid the knob 43 and the electric wire storage part 421.
In order to reduce the overall height of the luminaire 100, it is desirable to provide relief such as a hole, a dent, or a dent at a position corresponding to the knob 43 of the light source mounting portion 27 and the wire storage portion 421.
The knob housing part 274 of the light source mounting part 27 is a hole or a recess provided corresponding to the knob 43 of the battery unit 40, and realizes downsizing of the lighting fixture 100.
The battery case storage part 278 of the light source mounting part 27 is a depression or a dent provided corresponding to the electric wire storage part 421 of the battery unit 40, and the downsizing of the lighting fixture 100 is realized.

*** Explanation of effects of battery unit 40 ***
According to the present embodiment, battery unit 40 can be mounted efficiently and accurately by battery mounting portion 36 and fitting structure M.

  According to the present embodiment, the battery unit 40 can be disposed in the appliance mounting work space 70 provided between the main body 10 and the lighting device 30, and the work space and the battery unit 40 required for the mounting are required. Since the arrangement space can be shared, the lighting device 100 can be downsized.

*** Explanation of the configuration of the power supply terminal block 50 ***
The power terminal block 50 is a connector for supplying power from a commercial power source to the lighting device 30.
The power terminal block 50 has a cubic shape.
For example, a VVF cable is connected to the power terminal block 50.
One surface of the terminal body 51 is exposed to the outside from the terminal exposure hole 113 of the back plate 11 of the body 10, and a cable is connected to the terminal body 51 from the terminal exposure hole 113.
The power terminal block 50 is provided with a terminal for output to the lighting device 30, and the power is connected by connecting the output terminal and the input connector provided on the lighting circuit board 331 of the lighting device 30 with wiring. Supplied.

The terminal main body 51 of the power terminal block 50 has a ground terminal and is fixed to the back plate 11 by a terminal mounting plate 52.
The contact piece of the ground terminal is electrically connected to the metal terminal mounting plate 52.
The terminal mounting plate 52 is brought into contact with the metal back plate 11 of the main body 10 and screwed into the main body 10 with the metal screw 19 to ensure grounding conduction of the instrument.

When reducing the height of the lighting fixture 100, the power supply terminal block 50 is entirely stored in the terminal block storage portion 352 of the lighting device 30, and the back surface of the power supply terminal block 50 is the back surface of the lighting device 30. The power terminal block 50 is arranged so as to be aligned with each other. By bringing the terminal main body 51 into contact with the inner surface of the back plate 11 of the main body 10, it is possible to suppress the height of the instrument and ensure the grounding conduction.
One surface of the power terminal block 50 is exposed to the outside from the back plate 11, but the remaining five surfaces are covered with a resin surface of the device case 35 of the lighting device 30 except for a hole portion through which the harness is passed.

*** Explanation of effects of power terminal block 50 ***
According to the present embodiment, the power terminal block 50 is disposed in the center in the back direction of the main body 10 and is disposed in the center of the lighting device 30, so that the instrument mounting work space 70 can be secured on both sides inside the main body 10. This leads to improved workability of the lighting fixture 100.

*** 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 normal 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 corner outer surface of the device case 35 and is fitted in the lateral direction.

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 an inspection switch 62 and an inspection board 64 are attached. The unit housing 61 includes a flat portion 614 disposed 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 plane part 614 and the cylindrical arc part 615 are substantially orthogonal to each other.
The inspection switch 62 is a switch operated by a person in the vertical direction from the outside of the lighting fixture. 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 notch 276 exist in the vertical direction.
The coil spring 63 is a spring for always pulling the inspection switch 62 in the back direction.
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 checks whether or not the light source 26 is turned on with the electric power of the battery unit 40.
The inspection board 64 has a charge monitor 65 for confirming the state of charge 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 the internal components of the lighting fixture 100 or the inner surface of the lighting fixture.
As the fixing mechanism 611, a lateral claw 612 and a lateral claw 613 that are formed to protrude in the lateral direction and fit in the lateral direction are suitable.
The horizontal claw 612 is a claw formed so as to protrude laterally from the end of the flat portion 614 of the unit housing 61 toward the side surface 353.
The horizontal claw 613 is a claw formed so as to protrude in the horizontal direction from the end of the cylindrical arc portion 615 of the unit housing 61 toward the outer peripheral surface 354.
The horizontal claws 612 and the horizontal claws 613 are claws formed in a direction orthogonal to the horizontal direction.
The unit housing 61 is fixed to the outer surface of the lighting device 30 by the lateral claws 612 and the lateral claws 613 without using a tool.
The unit housing 61 does not protrude from the same plane as the side surface 353. Further, it does not protrude from an arc surface having the same radius as the outer peripheral surface 354.

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

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

*** Explanation of structure and assembly of inspection unit 60 ***
A method for assembling the inspection unit 60 will be described.
First, the coil spring 63 is set on the body of the inspection switch 62 and is 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 a coil spring, and the inspection switch 62 is always positioned in a state of being pushed up in the instrument installation state.

Next, the inspection substrate 64 is fitted into the substrate claw provided in the unit housing 61. In this state, the inspection switch side connector 3371 of the inspection switch harness 337 coming out from the device case 35 of the lighting device 30 is attached to the inspection switch connector 66 of the inspection board 64.
Thereafter, the unit housing 61 is attached to the inspection unit mounting portion 351 provided in the inspection switch side case 32. When the unit casing 61 is attached to the inspection unit mounting portion 351, the lateral claws 612 provided on the unit casing 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 direction at the time of insertion is a horizontal direction orthogonal to the vertical direction in which the inspection switch 62 is operated. This is to prevent the unit housing 61 from being detached from the inspection switch side case 32 when the inspection switch 62 is operated.

  On the other hand, if only the hooking in the horizontal direction is performed, the fixing in the vertical direction is not performed, and it is easily detached. Therefore, the protruding claws 671 are also fixed in the vertical direction. That is, in order to restrict the vertical movement, the unit casing 61 is attached to the wall surface in the back direction of the protruding claw 324 of the inspection unit mounting portion 351 by using the lateral movement of attaching the unit casing 61 to the apparatus case 35. What is necessary is just to slide the wall surface of the opening direction of the protrusion nail | claw 671 from a horizontal direction, and hook a protrusion nail | claw. In the vertical direction, the wall surface in the opening direction of the projecting claw 671 of the unit housing 61 is in contact with the wall surface in the rear direction of the projecting claw 324 of the inspection unit mounting portion 351, so the inspection unit 60 moves in the opening direction. I can't.

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

The place where the inspection switch 62 is fixed is the lighting circuit board 331 side, but 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. They are arranged so as to overlap with a vertical horizontal projection plane. Therefore, it is desirable that the circuit components of the lighting circuit board 331 be as low as possible at the location where the inspection board 64 is arranged.
By doing so, it becomes possible to arrange three circuit boards in parallel, and the boards can be arranged efficiently even in a small space of the main body 10.

*** Explanation of effects 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 of 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. FIG.
In the second embodiment, differences from the first embodiment will be described.
*** Explanation of structure and structure ***
Some emergency lighting fixtures have different illuminance ranges, and different emergency lighting times by battery units.
In addition, the battery unit needs to increase its capacity according to the output of the light source 26.

When the illuminance ranges are different, it is possible to cope with the problem 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 cope with the problem 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 increasing the capacity, the main body 10 is moved upward or downward or laterally. The battery unit 40 having an enlarged shape can be used, and the battery can be handled as a C cell or by increasing the number of cells.

Increasing the capacity of the battery unit 40 can be handled by changing the cell size or number. 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 case of the battery unit 40 without changing the fitting structure M using the guide rib 46 with the lighting device 30. .
As for the method of changing the shape of the battery unit 40, there are a case where the tool diameter is enlarged as shown in FIGS. 19 and 20, and a case where the tool diameter is enlarged as shown in FIGS. .
When expanding in the instrument height direction, it is possible to cope by changing the instrument height while keeping the instrument diameter the same.

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

In the instrument embedded in the ceiling shown in FIG. 20, the instrument height does not affect the design surface, so it is desirable to change the instrument height without changing the instrument diameter.
In the battery unit 40 shown in FIG. 19, a part of the battery unit is arranged in the opening direction from the lighting device 30 to the opening 101.
A 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.
In the appliance embedded in the ceiling shown in FIG. 20, the enlarged portion N of the battery unit 40 is arranged on the side where the light source unit 20 of the lighting device 30 is present. Since the enlarged portion N of the battery unit 40 is located 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, the fixture mounting is performed. The movement of the metal fitting 14 is not hindered.
In the appliance embedded in the ceiling shown in FIG. 20, it is difficult to ensure that the vertical length K3 of the heat shield space 72 is 10% or more of the height T of the lighting fixture 100, but there is a gap of 5% or more. 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 in the first embodiment, 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 appliance directly attached to the ceiling shown in FIG. 22, when the appliance height is changed, the amount of protrusion from the ceiling surface increases, so it is desirable to increase the appliance diameter while keeping the height the same.

In the appliance directly attached to the ceiling shown in FIG. 22, the main body 10 has a pair of appliance attachment holes 115 in the work space arrangement direction X.
The lighting device 30 is fixed to the main body 10 so as to cross a straight direction connecting the pair of instrument mounting holes 115 and not to block the instrument mounting holes 115.
The appliance directly attached to the ceiling is fixed to the ceiling with screws, but by laying out the lighting device 30 in the center of the main body 10, an appliance installation work space 70 is formed at a symmetrical position from the appliance center, The instrument mounting hole 115 can be exposed in the opening direction. The instrument mounting hole 115 is formed in the working 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 work space for screwing to the ceiling can be secured.

  In the appliance directly attached to the ceiling shown in FIG. 22, since a space is formed 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. The device 30 is disposed in a space between a part of the outer peripheral surface 354 that is a side surface having a short side 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 be arranged at the center with respect to the main body 10. This is because, when drilling into the ceiling, a hole is drilled in the center where the appliance is mounted, and it becomes easy to mount the electric wire from the back of the ceiling to the power terminal block 50.

In the appliance directly attached to the ceiling shown in FIG. 22, the main body 10 is integral with the frame 29 of the light source unit 20, and the main body 10 is exposed in the air.
Therefore, it is desirable to eliminate the spaces S1 and S2 between the light source mounting portion 27 and the main body 10 shown in FIG.
Since the main body 10 is exposed in the air, the heat dissipation effect is enhanced and the temperature of the light source 26 can be lowered.

*** Explanation of effects ***
