Description

The present invention relates to a luminaire.
The present invention is suitable for battery-powered lighting fixtures and emergency lighting fixtures.
INDUSTRIAL APPLICABILITY The present invention is suitable for lighting equipment such as emergency lighting equipment embedded and fixed to a mounting portion such as a ceiling.

There has been proposed an emergency lighting apparatus characterized in that an LED substrate and a power supply substrate are thermally coupled (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.

In addition, there are presented emergency lighting fixtures in which two thermally separated spaces are provided in the fixture body, and a light source and a lighting circuit are housed in the respective spaces (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 of the storage spaces, 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 has been presented in which the heat generated by the LED is efficiently dissipated and irradiated for a predetermined period of time by the heat radiating unit provided with the plurality of heat radiating fins being in contact with the light source unit provided with the LED (for example, , Patent Document 3).
However, Patent Document 3 does not describe heat dissipation from the heat dissipation unit of the emergency lighting device to the outside of the device. When the heat dissipation part dissipates heat to the inside of the appliance, the ambient temperature of the LED is considered to rise, and it is conceivable to attenuate the luminous flux of the LED and shorten its life.

In addition, an emergency lighting apparatus has been proposed which allows the size of the fixture body to be reduced by projecting the lighting device to the side of the tool body, thereby reducing the diameter of the fixture installation hole and the design portion (for example, , Patent Document 3).
However, in the emergency lighting device described in Patent Document 3, the lighting device protruding to the outside of the device main body increases the space occupied by the device itself after installation, and consideration to adjacent construction materials and other devices is required. Be done.

Moreover, the emergency lighting fixture which inserts a battery from a battery insertion opening part, and attaches a battery to a battery attachment part is shown (for example, refer patent document 4).
However, Patent Document 4 does not describe the device of the guide used at the time of battery insertion of the emergency lighting device. Without the device of the guide, there is a possibility that the connector connection portion can not be fitted well, and there was a problem in the battery detachability.

In addition, the lighting equipment of the LED that is the main light source is disposed outside the fixture, the inspection switch and the monitor LED are provided separately from the LED board that is the main light, and the emergency lighting fixture is arranged beside the LED that is the main light source. Are 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 influenced by the heat of the main light source LED. In addition, 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, the change can not be easily made.

In addition, an emergency lighting apparatus has been proposed in which an LED for monitoring is mounted on the same substrate as the LED serving as the main light source and the 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 disposed, the lighting device is disposed outside the fixture although there is a degree of freedom in arrangement. As a result, there is a problem in that the installation and installation of the appliance is restricted.

JP 2012-004050 A (refer to paragraph “0009”) JP 2012-185932 A (refer to paragraph “0010”) JP 2014-032868 A (refer to paragraphs “0064” to “0066”) JP, 2008-262770, A JP 2012-084324 A (see paragraph “0031”)

  In the case of a blackout due to a fire etc., the lighting fixtures for the construction and installation standards are defined by the Building Standard Law so as to secure a certain illuminance at the time of the blackout and to evacuate quickly.

  The emergency lighting device to be turned on at the time of a power failure at the time of fire occurrence etc. must secure a predetermined brightness (floor surface illuminance at 1 lx at high temperature) even in 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 heat of the LED.

  In addition, the special-purpose emergency lighting equipment equipped with only the emergency light source is in a state where the battery is being charged during normal use except during a power failure, and the light source is not lit, so it has a presence as a lighting equipment. The smaller one is preferable, and the reduction of the installation space and the power saving are required.

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

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

  Further, in the embodiment of the present invention, it is desired to miniaturize the lighting apparatus and to 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 apparatus.

  In addition, 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 relates to a light source unit attached to an opening of a lighting fixture,
Light source,
A light source attachment portion attached with the light source;
A ring-shaped frame fixed to the light source mounting portion and covering the opening;
It is characterized in that the frame and the light source mounting portion are thermally connected.

  According to the present invention, the heat of the light source can be efficiently dissipated to the frame.

*** Description 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 is structured to sandwich the light source 26 with 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 feed terminal of the socket 24. The connector 243 is fixed to the connector fixing hole 272 of the light source attachment portion 27 to prevent 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 attaching portion 27 through the socket 24, the material of the socket 24 is preferably a material having a high thermal conductivity.
In addition, a heat radiation sheet or grease may be applied between the light source attachment portion 27 and the socket 24 to reduce the contact thermal resistance.

The lens 21 is disposed on the light emitting surface side of the socket 24.
In order to fix the positions of the lens 21 and the socket 24, positioning mechanisms are provided at positions facing the socket 24 and the lens 21 respectively.
Specifically, as shown in FIG. 8, the lens 21 is provided with a recess-shaped 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. The part 241 is provided.
In FIG. 8, the concave portion 211 of the lens 21 and the convex portion 241 of the socket 24 are provided at three locations, but the number 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, and in the present embodiment, the hemispherical or dome-shaped lens 21 protrudes from the frame 29. The shape of the lens 21 may be suitably changed according to the light distribution.
In addition, the lens 21 may not protrude from the frame 29.
The lens 21 is preferably made of a 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 device, the outer shell of the lens 21 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 shape that protrudes in a hemispherical or dome shape from the lens hole 295 of the frame 29, and light is emitted from the protruding lens surface. At this time, when 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 light fixtures attached to a low ceiling of 2-3 m in height have a light intensity peak with a shallow angle (60 °), so light is provided by the frame 29 and inspection switch 62 in the form of a pull rod. May be blocked.
Therefore, the arrangement of the lens 21 and the inspection switch 62 needs to be implemented 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.
In addition, a projecting portion 291 having a convex shape is provided around the lens hole 295 of the frame 29, and the lens 21 is disposed in the light emitting direction. As described above, the vertical position of the lens 21 and the inspection switch 62 is shifted so as not to affect the light distribution.

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

  The frame mounting 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 a shape that narrows in width toward the tip according to the shape of the main body 10. As shown in FIG. 10, W1> W2.
The fixing of the main body 10 and the frame 29 requires a holding power of a certain level or more. Therefore, when holding using the elasticity of the frame mounting bracket 25, a certain width is required. On the other hand, since the main body 10 is cylindrical and the cross section is circular and the cross-sectional shape of the frame mounting bracket 25 is straight, both ends of the mounting plate 253 are main bodies when the width of the mounting plate 253 becomes more than a certain width. It interferes with the ten 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, it is necessary to bend and attach a large spring by that amount.
Therefore, in order not to interfere with the main body 10 while maintaining the holding power, the mounting plate portion 253 at the tip of the frame mounting bracket 25 is fit to the shape of the main body 10 and the width is narrowed toward the tip. Even in the state, it is possible to secure the holding power.

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 for fixing the frame 29 and the light source attaching portion 27 is a three-forked portion 2511 having a forked shape, and three teeth are formed in the three-forth portion 2511. The teeth at both ends of the fork 2511 are present at both ends of the bridge insertion hole 273. The teeth at both ends of the fork 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 teeth. 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.
As shown in FIG. 12, the central teeth of the fork 2511 are inserted under the bridge 293. At the completion of insertion of the center tooth of the fork 2511 into the bridge 293, the cut and raised portion 255 is caught on the outer wall of the bridge insertion hole and the frame attachment 25 can not be removed. After the light source mounting portion 27 is fixed to the frame 29, the cut and raised portion 255 prevents the frame mounting bracket 25 from being detached.

  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. Further, since the frame attachment bracket 25 brings the frame 29 and the light source attachment portion 27 into close contact, it has a function of bringing the lens 21 into close contact with the frame 29 and the socket 24.

Here, the method of assembling the light source unit 20 will be described using the exploded perspective view of FIG. 5.
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 attaching 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 movement of the lens 21 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 projecting portion 291 of the frame 29.
When the frame 29 and the light source attachment portion 27 are aligned, as shown in FIG. 12, the bridge insertion hole 273 provided in the thin portion 275 of the light source attachment 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 by the height I than the thickness of the thin portion 275 of the light source attachment portion 27, and the central tooth of the three fork 2511 of the frame attachment 25 is inserted when viewed from the side. It can be done.

As shown by the arrows 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 cut and raised portion 255 of the central tooth enters the bridge insertion hole 273. The frame mounting bracket 25 is fixed to the frame 29 in the closed state.
The frame mounting bracket 25 has cut and raised 255 on the center teeth, and the cut and raised 255 is caught on the outer wall of the bridge insertion hole 273 when insertion is completed, so that the frame mounting bracket 25 may be detached even when force is applied radially outward. It can prevent.
As described above, the light source attachment portion 27 and the frame 29 are fixed only by the frame attachment bracket 25 and do not use a screw or an adhesive.
Thus, the light source unit 20 is completed.

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

  On the other hand, the light source unit 20 is arrange | positioned via the heat blocking space 72 with respect to the lighting device 30 and the battery unit 40, as shown to BB sectional drawing of 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 attaching 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 crucible 13 via the space S1. The light source attachment portion 27 has an outer circumferential surface 277 along the inner circumferential surface of the main body 10.
An outer peripheral surface 277 of the light source attaching portion 27 is disposed to the inner peripheral surface of the main body 10 via a space S2. Thus, since the space S1 and the space S2 exist between the light source attaching 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 dissipation to the outside air takes place from the frame 29.

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

According to the present embodiment, since the frame 29 thermally connected to the light source attaching portion 27 is provided, and heat generated from the light source 26 can be dissipated through the frame 29, the life of the light source is extended.
According to the present embodiment, since the light source unit 20 is thermally separated from the lighting device 30 and the battery unit 40 which are internal components of the main body 10, the degree of freedom in the layout in the instrument is improved, and the instrument can be miniaturized. Can be realized.

  According to the present embodiment, by using the socket 24, the light source 26 is electrically isolated from the light source attachment portion 27 and the frame 29.

Further, since the frame 29 and the light source attachment portion 27 are attached by sliding the frame attachment bracket 25 in the lateral direction, there is no risk of the frame 29 falling in the vertical direction.

  According to the present embodiment, the mounting plate portion 253 of the frame mounting bracket 25 is tapered to be along the curved surface of the main body 10, so that the amount of deflection can be reduced, and the workability improves. It is possible to prevent the stagnation.

  According to the present embodiment, by using the incombustible material, the lighting fixture 100 can be used as an emergency lighting fixture.

  According to the present embodiment, by projecting the lens 21 to the frame 29, the floor surface can be irradiated without blocking light.

According to the present embodiment, as the light source mounting portion 27 and the frame 29 are fixed by sandwiching the lens 21 only by the slide of the frame mounting bracket 25, the assemblability is improved.
In addition, since there is no fixing mechanism for fixing only the lens, the number of parts can be reduced.

In this state, the inspection switch connector 3371 of the inspection switch harness 337 taken out of 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 on the inspection switch side case 32. When attaching the unit housing 61 to the inspection unit mounting portion 351, the horizontal claw 612 provided in the unit housing 61 is inserted into the horizontal claw hole 323 provided in the side surface 353 of the inspection switch side case 32, and the horizontal claw 613 Is inserted into the lateral claw hole 323 provided on the outer peripheral surface 354 of the inspection switch side case 32.
The insertion direction is a lateral direction orthogonal to the longitudinal direction in which the inspection switch 62 is operated. This is to prevent the unit housing 61 from coming off the inspection switch side case 32 when the inspection switch 62 is operated.

  On the other hand, since only the hooking in the lateral direction is not fixed in the vertical direction and is easily detached, the projecting claws 671 are provided and fixed also in the vertical direction. That is, in order to restrict longitudinal movement, the unit casing 61 is mounted against the wall surface in the back direction of the protruding claw 324 of the inspection unit mounting portion 351 using the movement in the lateral direction for attaching the unit casing 61 to the device case 35. The wall surface in the opening direction of the protruding claws 671 may be slid from the lateral direction to hook the protruding claws. Since the wall surface in the opening direction of the protruding claw 671 of the unit housing 61 is in contact with the wall surface in the back direction of the protruding claw 324 of the inspection unit mounting portion 351 in the vertical direction, the inspection unit 60 moves in the opening direction I can not do it.

Therefore, as for the circuit component of the lighting circuit board 331, it is desirable to use a component with a height as low as possible in the place where the inspection board 64 is disposed.
By doing this, 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.

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

Second Embodiment
In the second embodiment, points different from the first embodiment will be described.
*** Description of structure and structure ***
Some emergency lighting fixtures have different illumination ranges, and some have different emergency lighting times due to battery units.
In addition, the battery unit also needs to be increased in capacity according to the output of the light source 26.

When the illuminance range is different, it is possible to cope 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 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). However, in the case of increasing the capacity, the battery unit 40 in the main body 10 is upward or downward, or in the lateral direction. The battery unit 40 may be expanded in shape, and the battery may be a C cell, or the number of cells may be increased.

When increasing the capacity of the battery unit 40, it is possible to cope with this by changing the size or number of cells. At that time, it is necessary to change the shape of the battery unit 40, but this is dealt with by enlarging the outline of the case of the battery unit 40 without changing the fitting structure M using the guide rib 46 with the lighting device 30. .
As a method of changing the shape of the battery unit 40, as shown in FIGS. 19 and 20, the case of enlarging in the height direction of the device and the case of enlarging the diameter of the device as shown in FIGS. .
When it expands in the instrument height direction, it is possible to cope by changing the instrument height while making the instrument diameter the same.

On the other hand, when the instrument diameter is enlarged, it is possible to cope by changing only the instrument outer shape without changing the instrument height.
These are suitably selected according to the form of an instrument.

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

The battery unit 40 shown in FIG. 21 has a semi-cylindrical shape, has the same fitting structure M as that of the first embodiment at 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 case of the device directly attached to the ceiling shown in FIG. 22, if the height of the device is changed, the amount of protrusion from the ceiling surface increases, so it is desirable to enlarge the diameter of the device while making the height the same.

In the device directly attached to the ceiling shown in FIG. 22, the main body 10 has a pair of device 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.
Appliances attached directly to the ceiling will be fixed to the ceiling with screws, but by laying out the lighting device 30 in the center of the main body 10, the appliance mounting work space 70 is formed at a symmetrical position from the center of the appliance, It is possible to expose the tool mounting hole 115 in the opening direction. The tool attachment 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 tool mounting hole 115 in the back direction of the tool mounting work space 70 of the back plate 11, a screwing work space to the ceiling can be secured.

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

  Also in the device directly attached to the ceiling shown in FIG. 22, the power supply terminal block 50 is desirably disposed at the center of the main body 10. This is because when drilling on the ceiling, the center to which the tool is attached is drilled, and the attachment of the electric wire from the ceiling to the power supply terminal block 50 is facilitated.

In the device 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 to 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. 13 and bring the light source mounting portion 27 into contact with the main body 10 to transfer heat from the light source mounting portion 27 to the main body 10.
