Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to improvements in the construction of luminaires to facilitate the installation and maintenance of the luminaire, and more particularly to the installation of the luminaire in buildings. TECHNICAL FIELD The present invention relates to a technique for separating a structure of a lighting device for easy and economical replacement and maintenance.

The present invention is mainly intended for application to a built-in type lighting fixture such as a downlight, but is a general-purpose one that can be applied to installation of a fixture other than a lighting fixture in a building. .

[0003]

2. Description of the Related Art An embedded luminaire represented by a downlight generally has a fixture for fixing the luminaire to a building and an electric component such as a lamp socket or a wiring terminal block. It is fixedly assembled to the body of the device and has an integral structure that cannot be separated from each other. Such a conventional embedded luminaire having such an integrated structure is generally installed in a building by the following process, for example, in the case of a downlight.

First, at the stage of construction work, holes for attaching downlights are formed in the ceiling where the downlights are to be installed, and work is performed to connect a power supply line from the power source to the holes. After this, the downlight is fitted into each hole.At this time, electrical work for connecting the power supply line and the downlight is also performed at the same time, after which the downlight is screwed into the hole and an appropriate fastening method is applied. The installation work is completed by this.

[0005]

SUMMARY OF THE INVENTION One problem with the conventional lighting fixture installation process described above is that the installation of the lighting fixture requires electrical work. Since electrical work is legally required to be done by a specialist, it cannot be done by others. for that reason,
It cannot be said that the electrical work engineer does only the power distribution and wiring work, and the electrical work engineer does not participate in the subsequent installation of the lighting equipment.

Another problem is that it is not easy and economical to update the lighting equipment or change the installation position.

[0007] That is, since the lighting equipment once installed has a long life especially in electrical parts such as sockets, when the life is expired, the old lighting equipment must be removed and replaced with a new lighting equipment. Further, when it is desired to change the mounting position and specifications of the lighting equipment from the original one after a few years, it is necessary to change the mounting position and replace the lighting equipment.

In such a case, since all parts of the conventional luminaire are integrally assembled, even if, for example, only the socket is desired to be replaced or the light distribution specifications are to be changed, only the target part is replaced. No, you have to replace the entire luminaire. Therefore, it is uneconomical for the user, and it is necessary to remove the old lighting fixture and attach a new one, and further, the electric work by a specialist must be involved. Furthermore, in some cases, the ceiling surface and the like may be damaged during the construction, so that the interior construction work must be redone.

In addition, when the installation position of the lighting fixture is changed, it is necessary to make a new hole for mounting and fixing the lighting fixture on the ceiling surface or the like, and to repair the unnecessary hole portion. In addition to that, it is necessary to carry out electrical work such as laying the power supply line to a new installation location.

As described above, when the conventional lighting equipment is replaced or the installation position is changed, as a result, large-scale construction must be performed.

These problems are not limited to lighting equipment,
The same applies to appliances of the type that are mounted and fixed to buildings, such as security sensors and some types of audio equipment.

The present invention has been made in consideration of the above circumstances. A first object of the present invention relates to an electric appliance which is mounted and fixed to a building represented by a lighting apparatus. The purpose is to make it possible to change specifications easily with relatively simple construction.

A second object of the present invention is to enable replacement of life parts and specification changes, particularly for lighting equipment, without replacing the entire lighting equipment.

Further, a third object of the present invention is to provide a new improvement mainly for increasing the degree of freedom of specification regarding the structure of the lighting equipment.

[0015]

In order to achieve the above first object, the present invention provides a shape suitable for a hole to be fitted into a hole having a predetermined shape and a predetermined size formed in a building member. A frame body having an outer periphery having a size and an inner periphery forming a space for housing a predetermined electric appliance;
There is provided an electric appliance installation frame including an appliance attaching / detaching mechanism for detachably fixing the electric appliance to the frame main body when the electric appliance is fitted into the inner periphery of the frame main body.

In order to achieve the above-mentioned second and third objects, the present invention provides the following various types of lighting fixture structures.

The first type of luminaire includes a power supply unit for supplying power to a light source lamp, a light distribution unit including an optical component for controlling distribution of light emitted from the light source lamp, and a power supply unit. And a coupling mechanism for coupling / separatingly coupling the light distribution unit.

The second type of luminaire includes a socket part including a socket for setting a light source lamp, and a mirror connected to the socket part for controlling distribution of light emitted from the light source lamp. With a substantially cylindrical light distribution unit,
An air intake hole penetrating from the inner space of the light distribution part to the outer space is provided on the peripheral wall of the light distribution part near the opening at the tip of the mirror, and the socket part receives heat from the light source lamp outside the light distribution part. It has a heat dissipation mechanism for releasing into space.

A third type of luminaire comprises a tilter attached to a building member, and a luminaire main body detachably attached to the tilter and including a light source and a light distribution control mechanism.

The fourth type of luminaire comprises a luminaire main body and a front attachment detachably attached to a light emission port of the luminaire main body for adjusting the emission direction or emission amount of light. .

[0021]

The above-mentioned frame for installing electric appliances can be attached to the hole formed in the building member in advance so that various electric appliances can be detachably fixed to the frame. The electric appliances can be easily installed and replaced.

In the first type of luminaire, the power supply part such as the lamp socket and the light distribution part such as the mirror are detachable, so that the replacement of the life parts such as the socket only requires the power supply part. Also, when changing the specifications of the light distribution and the lamp, only the light distribution section and the power supply section need to be replaced.

In the second type of luminaire, especially in a downlight, air flows from the inner space of the light distribution section to the outer space through the air intake, so that the dirty air in the room is guided to the ceiling. As a result, the lighting equipment is prevented from being soiled.

In the third type of luminaire, the tilter and the luminaire main body can be attached and detached freely. Therefore, by preparing various tilts and various luminaire main bodies, various combinations of both can be selected.

In the fourth type of lighting fixture, various variations of the combination of the front attachment and the lighting fixture body can be selected.

The plurality of accessory circuit component mounting mechanisms 7 include, for example, the terminal block 17 shown in FIG. 1, a ballast 19 used for a light source lamp such as a fluorescent lamp which cannot use a commercial power source as it is, and a transformer. Alternatively, the power converter circuit such as a frequency converter (none of which is shown) can be attached / removed freely. When the lighting fixture attached to the frame body 1 can be used without converting the electric power supplied from the commercial power source, only the terminal block 17 is attached to the accessory circuit component attaching mechanism 7.

Depending on the lighting equipment mounted on the frame body 1, a transformer or a frequency converter (neither is shown) may be mounted on the accessory circuit component mounting mechanism 7. In addition to the attachment of these power conversion circuits, for example, an umbrella (not shown) that closes the hole 10 in the ceiling can be attached.

Further, the engaging portion connecting portion 13b is formed with a screw hole corresponding to the screw receiving portion 13e (see FIGS. 1 and 2).

The building material surface contact portion 13c is formed by bending the base portion 13a at a predetermined angle in a direction opposite to that of the pair of engaging claws 13d and the screw receiving portion 13e. As shown in FIG. 2, the building material surface contact portion 13c is configured to be capable of contacting the back surface (ceiling space) of the building material 27 when the frame body 1 is attached and fixed.

When the frame main body 1 is attached to the building material 27, the pair of engaging claws 13d engage with the appropriate teeth in the corresponding tooth row 5b in the manner as shown in FIG. On the other hand, when the screw receiving portion 13e is attached to the ceiling plate 27 or the like of the frame body 1, the screw 29 is screwed together with the screw hole formed in the engaging portion connecting portion 13b in a manner as shown in FIG. , Driver 31 and the like.

The screw receiving portion 13e and the screw hole are
As shown in FIG. 2, the screwdriver 31 and the like are provided at an angle that facilitates screw fastening work. A spacer (not shown) is inserted into the screw 29 as needed,
This spacer (not shown) functions to prevent the screw 29 from being overtightened.

The lid body 20 is formed in substantially the same shape as the frame body 1 and in substantially the same size as the inner peripheral side of the frame body 1 so that the lid body 20 can be attached to and detached from the frame body 1. . That is, the outer peripheral portion of the lid body 20 is formed with a step portion 20a that slightly protrudes circumferentially over the entire circumference. The step portion 20a is configured to position the attaching position of the lid body 20 to the frame body 1 by contacting the step portion 11 when the lid pair 20 is attached to the frame body 1.

The electric appliance installation frame having the above structure is attached and fixed to an appropriate place inside the room such as the ceiling plate 27 and a desired place outside the room by the following procedure. Hereinafter, for simplification, the case where the mounting position of the electric appliance installation frame is only the ceiling plate 27 will be described.

Each of the holes 25 of the frame for installing the electric appliance
In mounting the terminal block 17, first, the terminal block 17 is mounted to the accessory circuit component mounting mechanism 7 of each frame body 1. When the mounting work of the terminal block 17 is completed, the frame body 1 is lifted up to the vicinity of the hole 25 where the frame block 1 is to be mounted, and in this state, it is pre-wired on the primary side of the terminal block 17 in the ceiling or the like. A power supply line (basic wiring) 15 is connected.

When the work for connecting the power supply line 15 to the terminal block 17 is completed, the outer peripheral side of the frame body 1 is in the hole section 25a to be mounted, and the flange portion 9 of the frame body 1 is in the hole. The frame body 1 in the state of being in contact with the surface portion of the ceiling plate 27 near the portion 25, respectively.
Is retained. In this state, the engaging claws 13d of the two fixing fittings 13 are respectively engaged with the appropriate teeth in the tooth row 5b of the corresponding rack member 5a.

The teeth with which the engaging claws 13d are engaged are determined according to the thickness of the ceiling plate 27. As a result, the convex engaging portions 13f are engaged with the inner peripheral surface of the frame body 1 in a pressure contact state by the urging force in the inner peripheral direction of the frame body 1 generated in the respective fixing fittings 13, while contacting each building material surface. Part 13
The c is pressed against the back surface of the ceiling plate 27 by the downward urging force of FIG. As a result, the frame body 1 is temporarily fixed to the ceiling plate 27. When the frame body 1 is temporarily fastened to the ceiling plate 27, the cross section 25 a of the hole 25 is completely covered by the frame body 1.

After the frame main body 1 is temporarily fastened in this manner, the screw 2 is inserted into the screw receiving portion 13e and the screw hole.
9 are screwed together as shown in FIG. By fastening the screw 29 with the driver 31 or the like, the mounting and fixing of the frame body 1 to the ceiling plate 27 is completed while the frame body 1 and the ceiling plate 27 are in close contact with each other. Through the above steps, the attachment and fixing of the frame body 1 to all the holes 25 are executed.

When the above work is completed, the receiving wire 22 on the side of the luminaire 30 with respect to the core wiring 15 is passed through the terminal block 17.
(Or 24) will be connected.

If the light source lamp of the luminaire 30 shown in FIG. 3 is a fluorescent lamp, the luminaire 30 is lifted in the vicinity of the frame body 1 and is attached to the attachment circuit 7 different from the attachment circuit component attachment mechanism 7. Ballast 1 for circuit component mounting mechanism 7
Installation work of 9 is performed.

Next, the work of connecting the insertion plug 21b of the receiving wire 24 connected to the ballast 19 to the secondary side of the terminal block 17 is performed, and then the lighting fixture 30 is attached to the inner circumference of the frame body 1. The work of fitting and fixing to the side will be performed. On the other hand, when the light source lamp in the lighting fixture 30 does not require a power conversion circuit such as the ballast 19, the work of immediately connecting the plug 21a of the receiving wire 22 to the secondary side of the terminal block 17 is performed. After that, the work of fitting and fixing the lighting fixture 30 on the inner peripheral side of the frame body 1 is performed.

The work of mounting and fixing the lighting fixture (downlight) 30 to the frame body 1 is completed through the following processes. That is, the lighting fixture 30 is inserted into the frame body 1 from below the frame body 1.

The luminaire 30 has the cone 5
3 (shown in FIG. 3; the cone 53 will be described in detail later) is engaged with each instrument attachment / detachment mechanism 3 by the urging force of the plurality of instrument attachment / detachment mechanisms 3 in the inner circumferential direction of the frame body 1. Further, the lower step portion of the tip of the cone 53 comes into contact with the step portion 11 so as to be positioned and fixed in the frame body 1. Through the process described above, the work of attaching and fixing the lighting fixture 30 to the frame body 1 is completed. Lighting equipment 3 for each frame body 1 described above
The time required for mounting and fixing work of 0 is about 30 seconds.

To remove the luminaire 30 mounted and fixed to the frame body 1, first, a step of pulling out the luminaire 30 body from the frame body 1 is executed, and then the secondary side (outlet) of the terminal block 17 is connected. This can be performed only by executing the step of removing the inserted plug 21a or the inserted plug 21b. By performing the step of pulling out the main body of the lighting fixture 30 downward, the urging of the plurality of fixture attaching / detaching mechanisms 3 in the direction of the frame main body 1 is released, and therefore the removal of the main body of the lighting fixture 30 from the frame main body 1 is extremely easy. And the receiving wire 22
Since the connection between the receiving wire 22 (or 24) and the core wiring 15 can be released only by pulling out (or 24) from the secondary side of the terminal block 17, no tools or the like are required.

Since the portion where the main body of the lighting fixture 30 is not attached is still open and therefore does not look good, the above-mentioned lid 20 is attached. This lid 20 is attached
From the lower side of the frame body 1 to the step portion 2 of the lid body 20
It is completed by inserting 0a so as to abut the stepped portion 11 of the frame body 1.

That is, when the lid body 20 is attached to the frame body 1, the pair of elastic members 20b described above are brought into pressure contact with the upper end portion of the frame body 1 by their urging forces. Will be retained. It should be noted that the lid 20 can be removed from the frame body 1 very easily because it is only necessary to pull the lid 20 downward.

As described above, according to the electric equipment installation frame according to the embodiment of the present invention, the frame main body 1 of the electric equipment installation frame, the terminal block 17, and the lighting equipment 3 are provided.
0 is a separate structure, and the secondary side of the terminal block 17 is, for example, the plug 21a of the receiving wire 22 (or 24) of various lighting fixtures such as the lighting fixture 30 of FIG.
(Or 21b) is a pluggable outlet, so you can replace the originally installed luminaire with a new luminaire, attach the luminaire to a mounting position different from the design time, and differ from the design time. It is extremely easy to attach lighting equipment of different types and specifications (for example, replacement of normal lamps with fluorescent lamps, replacement of lighting equipment with different rated voltage or rated frequency).

That is, when performing the work such as the replacement of the luminaire or the change of the mounting position, the receiving wire 22 simply connected to the luminaire 30 of FIG. 3 from the secondary side of the terminal block 17.
(Or 24) plug 21a (or 21b)
It is only necessary to pull out the main body of the lighting fixture 30 from the frame main body 1 after removing. The above work is the power supply line (basic wiring)
Electrical work that requires the work of a specialist such as 15 wiring work or the hole 25 that is no longer needed is closed or a new hole 2 is created.
No large-scale work such as interior work such as drilling 5 is required.

When the frame body 1 is attached and fixed to the ceiling plate 27, the hole section 25a of the frame body 1 and the ceiling plate 2 are fixed.
Due to the contact with the surface and the urging force generated in the fixing bracket 13 in the inner circumferential direction of the frame body 1, the frame body 1 is
Since it is temporarily fastened to the ceiling plate 27, and in this state, it is attached and fixed by the screw 29 as shown in FIG. 2, so that the adhesion to the surface of the ceiling plate 27 of the frame body 1 and the hole section 25a (with suction). Is very good. Therefore, even if there is some vibration, there is no risk of loosening in the mounting and fixing state. Further, even if there is some variation in the thickness of the ceiling plate 27 in which the holes 25 are formed, the teeth with which the respective engaging claws 13d engage in accordance with the thickness of the ceiling plate 27 are the tooth rows 5b. Since it can be selected from the inside, the mounting portion of the frame body 1 is not limited by the plate thickness of the ceiling plate 27.

When the frame body 1 is mounted and fixed to the ceiling plate 27 or the like, first, the above-mentioned power supply line (that is, the main wiring) 15 is fixedly connected to the primary side of the terminal block 17. Therefore, at the time when the above-mentioned connection fixing work is completed, the energization inspection is carried out from the terminal block 17 side to make a defect on the power supply line 15 side (for example, connection failure between the main wiring 15 and the primary side of the terminal block 17, wiring failure, etc. ), It is possible to improve the inspection efficiency of the wiring work of the feeder line (basic wiring) 15. Further, after the completion of the energization inspection, the receiving wire 22 (or 24) is inserted into the secondary side of the terminal block 17 to carry out an energization inspection, and when any defect is detected as a result, the power supply line 15 side Based on the inspection result, it is possible to easily discriminate whether the failure is a failure on the power supply line 15 side or a failure on the load side of the lighting device 30 or the like (for example, device connection failure). it can. Therefore, in the unlikely event of an electrical accident such as a leak, if the above-mentioned accident location can be easily identified whether it is the power supply line (core wiring) 15 side or the lighting fixture side and the cause of the accident can be easily grasped. Instead, it is possible to take prompt measures against accidents.

Further, since the hole portion 25 when not in use can be easily closed by the lid 20, repair work of the ceiling plate 27 for closing the unused hole portion 25 and the power supply line ( It is not necessary to carry out large-scale construction such as wiring of the main wiring 15).

Further, as long as it is an embedded electric appliance having substantially the same shape and substantially the same size as the above-mentioned electric appliance installation frame, it is not limited to lighting equipment, and AV such as a speaker or a video camera is used.
Various electric appliances such as a device or a security sensor can also be attached to the electric appliance installation frame.

Furthermore, the frame for installing the electric appliance is
Various types of tilters such as a universal type tilter pull-out arm type (pull-down type) tilter, a plug type tilter, and a flange type tilter that can be tilted while holding a lighting fixture or the like can be attached. These various tilters will be described later.

In this embodiment, the case where the electric appliance installation frame is attached to the hole portion 25 formed in the ceiling plate 27 has been described. However, the electric appliance installation frame is not limited to the hole portion formed in the ceiling plate. It can be attached not only to holes formed at appropriate places in the room such as wall surfaces and floors, but also to furniture such as furniture, and it can also be attached to brackets etc. . Further, it can be mounted not only indoors but also to an appropriate place outdoors, for example, a structure installed on the ground or the like, and the mounting place is not limited. Further, the shape of the frame body 1 described above is not limited to the annular shape, and may be, for example, a rectangular shape, a rhombic shape, or a triangular shape.

FIG. 3 and FIG. 4 show an embedded lighting fixture (downlight) which can be detachably attached to the electric equipment installation frame.

The lighting fixture 30 has a structure in which the power receiving mechanism 33 and the optical mechanism 35 can be freely combined / separated by a simple operation without using a special tool or the like. The power receiving mechanism 33 includes a socket cover 39 and the socket cover 3

It has a cord (receiver wire) 22 connected to a light bulb socket 41 via a socket cover 39, and has a structure in which these respective parts 22, 39 and 41 are integrated.

On the other hand, the power conversion circuit components such as the terminal block 17 and the ballast 19 are not integrally formed with the power receiving mechanism 33 as in the conventional case, but are configured to be detachable from the frame body 1. Therefore, it is installed at a position separated from the power receiving mechanism 33. The reason why each of the above-mentioned auxiliary circuit components is installed at a position separated from the power receiving mechanism 33 is that the light bulb socket 41 and the light source lamp 42 (or 44) that configure the power receiving mechanism 33 (both are shown in FIG. 4). )
This is because it was decided to protect the above-mentioned accessory circuit parts from the effects of heat generation.

A plug 21a is attached to the end of the cord (receiver wire) 22. The plug 21a has a power receiving mechanism 33 and an optical mechanism 3 as will be described later.
5 and 5 are integrated as an embedded lighting fixture 30, and before they are fitted and fixed to the inner circumference of the frame body 1 described above, the secondary side (that is, an outlet) of the terminal block 17 described above.
Inserted in.

As shown in FIG. 3, the socket cover 39 includes a socket cover main body 43 having a substantially cylindrical shape, a connecting portion 45 having a substantially cylindrical shape integrally formed with the socket cover main body 43, and a socket cover. A plurality of fins 47 are formed on the side surface of the main body 43 at substantially equal intervals over the entire circumference.

In addition to the plurality of fins 47, a plurality of slit-shaped heat dissipation holes 43a are formed at predetermined intervals in a portion from the side surface of the socket cover body 43 to the top plate portion thereof. Inner top plate part 4
3b is a function as a heat sink and the bulb socket 41
It also has a function as a support fixing member. The inner top plate portion 43b is configured so that various light bulb sockets 41 can be detachably attached via screws or the like.

The plurality of heat dissipation holes 43a and the plurality of fins 47 ensure a sufficient heat dissipation cross section of the socket cover body 43, thereby promoting the heat dissipation effect of the socket cover body 43 and maintaining the life of the light source lamp. If possible, try. It should be noted that the power receiving mechanism 33 shown in FIG. 3 and the like is an example of what is adopted when the light source lamp used has a very large power consumption,
There are various power receiving mechanisms according to the type of light source lamp (for example, a fluorescent lamp, an incandescent lamp, a halogen lamp, etc.) connected to the lighting apparatus 30 shown in FIG. Be prepared.
