A mode for carrying out the present invention will be described below with reference to the drawings. However, the forms shown below are for embodying the technical idea of the present invention and do not limit the present invention. Further, in the following description, members of the same or the same quality are shown with the same name and reference numeral, and detailed description thereof will be omitted as appropriate. The size and positional relationship of the members shown in each drawing may be exaggerated to clarify the explanation.

FIG. 1 is a schematic diagram showing a living room in a state before the installation change of lighting in the building 1. Further, FIG. 2 is a schematic view showing the structure of the ceiling in the living room of the building 1 in the state of FIG. In addition, since the figure becomes complicated, in FIG. 2, the structure of the ceiling is shown by half of the entire ceiling shown in FIG. 1, and a part of the hanging material and wiring is omitted.

Building 1 is assumed to have a multi-story structure and a passage and a living room like a general office building, but it is not limited to this. For example, it may be a one-story building. Further, the installation change of the lighting may be a case where the lighting itself is changed to another lighting or a case where the position where the lighting is arranged is changed.

In building 1, the living room forms a space with the floor 2 as the lower surface, the wall 3 as the side surface, the ceiling 4 as the upper surface, and the window 5 as the side surface. Hereinafter, the space between the floor 2 which is the lower surface and the ceiling 4 which is the upper surface is referred to as a living room space. A living room without a window 5 and having only a wall 3 on the side surface may be used. Further, a plurality of air conditioners 90 and a plurality of lighting fixtures 99 are installed on the ceiling 4. The number of air conditioners 90 may be one.

In the building 1, the attic forms a space in which the ceiling 4 is the lower surface and the skeleton 6 is the upper surface and the side surface. Hereinafter, the space between the ceiling 4 which is the lower surface and the skeleton 6 which is the upper surface is referred to as an attic space. In the attic space, a plurality of hanging members 20 connected to the ceiling insert of the skeleton 6 are provided. The hanging member 20 includes a hanging member 21 connected to the field edge, a hanging member 22 connected to the air conditioner 90, and a hanging member 23 connected to the lighting fixture 99.

The ceiling 4 is formed by arranging a plurality of ceiling materials 40. The ceiling material 40 is supported by the hanging material 21. The hanging material 21 is connected to the ceiling insert of the skeleton 6, the field edge is connected to the hanging material 21, the ceiling material 40 is attached to the field edge, and the ceiling material 40 is fixed.

Further, in the attic space, a plurality of electric wirings 50 provided through pipes are provided for supplying power to electric connection devices such as an air conditioner 90 and a lighting fixture 99. Communication wiring for connecting to the network may be provided.

The air conditioner 90 and the lighting fixture 99 are installed on the ceiling 4 so as to be fitted into the opening formed in the ceiling material 40. The air conditioner 90 is connected to the hanging member 22, and the lighting fixture 99 is connected to the hanging member 23. Further, the air conditioner 90 and the lighting fixture 99 are each connected to the electric wiring 50 to receive power supply.

The living room space can be said to be a space having a ceiling 4 as a part forming the space and a space below the ceiling 4. Further, the attic space can be said to be a space having the ceiling 4 as a part forming the space and being above the ceiling 4.

FIG. 3 is a flow chart for explaining the process until the building 1 in the state of FIGS. 1 and 2 is constructed. Here, a typical example from the state of the vacant lot to the construction of the building 1 will be described. In the construction of a large-scale building such as an office building, the general contractor undertakes the order for the construction work, and the general contractor manages the entire construction work performed by various contractors.

First, the designer or designer designs the building 1 (step S1). In this process, the layout of the passage and the living room is determined, and the overall design of the building 1 is described in the design drawing. In addition, the building materials to be adopted and the electrical equipment materials such as lighting fixtures are decided to some extent, and the arrangement is also described in the drawing.

Next, building materials and construction machinery are prepared and foundation work is carried out based on the determined design (step S2). In this process, stable ground that can withstand the load of the building is secured by pile construction and earthwork. Here, the workers of the contractor who performs the civil engineering work mainly perform the work. It should be noted that not only the workers of the civil engineering contractor but also the workers of other contractors are doing the work.

Next, the skeleton work for forming the skeleton 6 of the building 1 on the stable ground is performed (step S3). The skeleton work starts from the foundation part and, if it has a basement floor, the basement part, and proceeds to the ground floor. The entire skeleton of Building 1 is completed by placing concrete, building columns, and assembling steel frames. In addition, concrete will be placed on the outer wall, rooftop, and under the floor of each floor.

Further, in the skeleton work, an insert is embedded in order to connect the hanging material 20 such as a hanging bolt in the later interior work. For example, a ceiling insert for fixing hanging bolts is fixed as a part of the slab when placing a floor slab (such as a reinforced concrete floor board) on the upper floor. Here, mainly the workers of the civil engineering contractor and the workers of the concrete contractor perform the work.

Next, the exterior work of building 1 is carried out (step S4). The outer shape of the building 1 is formed by the exterior work. Tiled exterior walls, window sashes, windowpanes, curtain walls, etc. can be installed. In addition, painting is also performed.

Next, interior work is carried out (step S5). In the interior work, the floor 2, the wall 3, and the ceiling 4 will be built. In the ceiling work for installing the ceiling 4, the hanging material 20 is connected to the ceiling insert provided in the skeleton work in step S3. Further, the field edges constructed in a grid pattern using a lightweight steel frame or the like are connected to and supported by the hanging member 21. Then, the ceiling material 40 such as the ceiling plate and the ceiling base material is attached. By supporting the ceiling material 40 to the hanging material 21 via the field edge, measures are taken to prevent the risk of the ceiling material 40 falling off.

For example, in Japan, the Building Standards Law and enforcement ordinances have provisions to prevent ceilings from falling off. One of them is that when a ceiling material that meets the predetermined conditions is provided, measures to prevent it from falling off, such as fixing it with a hanging material, are stipulated. In addition, when lighting fixtures and air conditioners are installed on the ceiling, it is necessary to directly connect and fix these ceiling installation fixtures to the hanging material according to their size and weight.

As a conventional example, for a small-weight ceiling-installed fixture such as a surveillance camera, emergency lighting, or smoke detector sensor, the ceiling-installed fixture itself is used as a ceiling material without being connected to a hanging material such as a hanging bolt. Can be installed. In this case, almost all the load of the ceiling fixture is applied to the ceiling material.

On the other hand, for embedded base lighting such as lighting fixture 99, ceiling-mounted base lighting, or heavy ceiling-installed equipment such as air-conditioning equipment 90, the ceiling-installed equipment itself is connected to a hanging material and fixed. After that, it is installed on the ceiling material. In this case, the hanging material connected to the ceiling fixture supports almost all the loads of the ceiling fixture.

Instead of installing the ceiling insert when placing concrete, it is also possible to fix the hanging material 20 by hitting an anchor on the concrete after placing. However, it is preferable to install it in advance in consideration of efficiency and safety. Where it is known that the suspension will be provided, it is desirable that the placement of the ceiling insert be determined at the design stage and that it be embedded during the placement of concrete.

Further, in the interior work, before the formation of the ceiling 4 by the ceiling material 40 is completed, the work of suspending the piping and the air-conditioning duct and the work of passing the electric wiring through the pipe are also performed. Further, the work of providing the electric wiring 50 in the space behind the ceiling is also performed.

In the wiring work for providing the electrical wiring 50, the worker provides the required number of electrical wiring 50 based on the design drawing. The number of required electrical wirings 50 is determined according to the number of electrical connection devices such as the air conditioner 90 and the lighting fixture 99 installed behind the ceiling.

Note that these operations may be performed after the formation of the ceiling 4 is completed. However, if the work space in the attic space is small, it becomes difficult to perform these tasks. On the other hand, since the attic is a space that normally does not allow people to enter, it is not preferable to secure an excessively large work space.

Here, the work such as installing the duct in the ceiling and fixing the ceiling material 40 with the hanging material 21 is performed by a worker of a contractor who performs interior work. On the other hand, the work of providing the electrical wiring 50 is performed by a professional worker who can perform electrical work because there is a risk of electric shock or the like. In Japan, electrical work such as wiring work by persons who are not qualified as electricians is not permitted. In the construction of buildings, safety is taken into consideration by having various specialized contractors carry out their respective specialized work.

Next, when the interior work is completed and the floor 2, wall 3 and ceiling 4 are completed, the installation work is performed (step S6). In the installation work, various facilities required for actually using the building 1 are installed. For example, equipment for electricity, gas, water, drainage, air conditioning, toilets, disaster prevention, broadcasting, etc., and equipment such as lighting, escalators, and elevators are installed. These works are carried out by workers of business operators such as electrical work, telecommunications work, water supply facility work, firefighting facility work, and cleaning facility work.

Here, in time for the installation work of the lighting, the manufacturer of the lighting fixture manufactures the lighting fixture 99 necessary for the construction and delivers it to the electrical material trading company that manages the electrical equipment materials (step S7). In addition, the electrical materials trading company manages the inventory of materials such as switches, outlets, electric wires, cables, switchboards, antennas, distribution boards, intercoms, fire alarms, etc., as well as lighting fixtures, for installation work. The necessary electrical equipment materials are supplied in the required amount (step S8).

In the air conditioning equipment construction, the air conditioning equipment 90 is installed on the ceiling 4. The operator connects the air conditioner 90 to the suspension member 22, and with the air conditioner 90 connected to the suspension member 22, fits the air conditioner 90 into the opening formed in the ceiling 4.

In the lighting installation work, the lighting fixture 99 is installed on the ceiling 4. The worker connects the lighting fixture 99 to the hanging material 23, fits the lighting fixture 99 into the opening formed in the ceiling 4 in a state where the lighting fixture 99 is connected to the hanging material 23, and installs the lighting fixture 99 on the ceiling 4. To do. When the lighting fixture 99 is connected to the hanging member 23, the lighting fixture 99 is fixed to the skeleton 6 via the hanging member 23.

The opening of the ceiling 4 for installing the air conditioner 90 and the lighting fixture 99 can be formed by making a hole in the ceiling material 40. The opening in the ceiling material 40 may be provided at the stage of ceiling installation work instead of being provided at the stage of equipment work.

Further, when installing an electric connection device such as an air conditioner 90 or a lighting fixture 99, the work of connecting the electric connection device and the electric wiring 50 is also performed. As a result, the electrically connected device can be electrically connected to the external power source via the electric wiring 50 and can receive power supplied from the external power source.

If the connection work with the electric wiring 50 is performed with the lighting fixture 99 connected to the hanging member 23, the lighting fixture 99 can be operated in a stable state. Further, since the electric wiring 50 is arranged in the space behind the ceiling, it is preferable that the connection with the electric wiring 50 is completed before the work of fitting the lighting fixture 99 into the opening of the ceiling material 40. This is because if it is fitted first, the connection work with the electric wiring 50 must be performed in the space behind the ceiling, which makes the work difficult.

Note that the connection work of the electrical wiring 50 here is also performed by a professional worker who can perform electrical work because there is a risk of electric shock. For example, in Japan, an electric wiring 50 is connected to a power adapter of a lighting fixture 99 by a worker who is qualified as an electrician. Another worker may perform the process from connecting to the hanging material 23 to the point where it is installed on the ceiling 4, or a worker having a qualification as an electrician may perform the process from connecting to the suspension material 23 to the point where it is installed on the ceiling 4.

In the case of a building 1 such as an office building, a small ceiling installation device such as a downlight is provided for lighting in a narrow space such as a passage, and a large base light such as a lighting fixture 99 is provided in a large space such as a living room. A design that can be provided is conceivable. Although it is possible that a small lighting fixture is partially installed in the living room, it is more effective to adopt a large lighting fixture in order to efficiently illuminate the entire living room.

<First Embodiment>
Next, the installation process of the lighting fixture in the building according to the first embodiment will be described. FIG. 4 is a schematic view showing a living room in a state after the lighting installation is changed in the building 1. In the installation process according to the first embodiment, in order to make the explanation easy to understand, a process in which the installation of the lighting is changed from the state shown in FIGS. 1 and 2 to the state shown in FIG. 4 will be described as an example.

In the building 1 after the installation change, the lighting fixtures installed on the ceiling 4 are changed from the lighting fixtures 99 to the lighting fixtures 10. That is, the installation of the lighting is changed from the lighting lamp 99 to the lighting lamp 10, and the building 1 is being renovated. In addition, the lighting fixture 10 is also installed in a place (ceiling material 40) that was not installed before the installation change. When viewed from the living room space side, there are no other changes.

In addition, the layout of the living room may be changed. For example, the installation position and the number of the air conditioner 90 may be changed, the ceiling material 40 may be completely replaced, the window glass may be replaced, or the floor tiles may be replaced. In addition, it is not necessary to install the lighting fixtures in the places where they were not installed before the installation change, or changed so that the lighting fixtures are not installed in the places where the lighting fixtures were installed before the installation change. You may.

Here, the lighting fixture 10 will be described. The lighting fixture 10 has a performance equivalent to that of the lighting fixture 99 in terms of the performance of the lighting fixture, and realizes a lighting fixture that does not need to be connected to a hanging material and fixed in the installation work of the lighting. It was done. That is, the lighting fixture 10 is large enough to be handled as equivalent to base lighting and can illuminate a wide range, but is lightweight enough not to require a hanging material.

Here, such a lighting fixture is referred to as a lightweight large lighting fixture. In the building 1, the lighting fixture 99 installed on the ceiling 4 of the living room is changed to the lighting fixture 10, so that the building 1 in which the lightweight and large lighting fixture is installed is created.

Further, in the present specification, at least one of whether the total luminous flux is 2500 lm or more, the area of the light emitting surface which is the surface closest to the floor is 45000 mm2 or more, or 100 or more light sources such as LEDs are arranged. A lighting fixture that satisfies the conditions is called a large lighting fixture. In addition, a luminaire that can be installed on the ceiling without having to be directly fixed to the hanging material is referred to as a lightweight luminaire.

Lightweight large lighting fixtures are lighting fixtures that are both large lighting fixtures and lightweight lighting fixtures. Further, as a condition for determining a lightweight large-sized lighting fixture, in addition to these, a condition that the weight is 0.5 kg or more may be further specified, and a condition that the weight is less than 2.5 kg is further specified. In addition, it may be specified.

An example of the lighting fixture 10 is shown in FIGS. 5 to 7. FIG. 5 is a schematic perspective view of the lighting fixture. FIG. 6 is a schematic view for explaining the structure of the lighting fixture. FIG. 7 is a schematic perspective view of a light source mounted on a lighting fixture.

The lighting fixture 10 has a base plate 111, a cover 112, a buffer portion 113, a mounting portion 12, a substrate 114, and a light source 115. The base plate 111 functions as a reinforcing plate or a heat radiating plate in the lighting fixture 10. For example, it is a metal plate formed in a rectangular shape. For example, the metal plate can be formed of aluminum as a material.

In the present specification, the "light source" refers to a member that emits light, and the light source may be a light emitting element typified by an LED, or a combination of a light emitting element and a wavelength conversion member. You may. The "wavelength conversion member" refers to a member that converts a part or all of the light emitted by the light emitting element into light of another wavelength, and examples thereof include a phosphor member.

The cover 112 is provided so as to cover the light source 115 arranged on the substrate 114. In addition, it has translucency with respect to the light emitted by the light source 115. The cover 112 is formed in a milky white color having light diffusivity, for example, in which titanium oxide or the like is dispersed in a resin material. As the resin material, for example, an acrylic resin can be adopted, and for example, a polymethyl methacrylate resin can be adopted.

The cushioning portion 113 is provided on the outer periphery of the ceiling installation surface of the base plate 111. The buffer portion 113 prevents the ceiling installation surface of the base plate 111 from coming into direct contact with the ceiling 4 (or the ceiling material 40) to buffer the impact. Further, the mounting portion 12 corresponds to a mounting portion for mounting on the ceiling material 40.

The substrate 114 is, for example, a resin or ceramic insulating substrate, and has a light source arrangement surface on which a plurality of light sources 115 are arranged. Further, a conductive pattern for supplying electric power to the light source 115 is provided on the light source arrangement surface of the substrate 114. The material of the conductive pattern can be appropriately selected according to the main material of the substrate 114. For example, in the case of a substrate made of a ceramic material, the conductive pattern preferably has a high melting point that can withstand the firing temperature of the ceramic sheet. For example, the material of the conductive wiring may be made of a metal having a high melting point such as tungsten and / or molybdenum. Further, another metal material such as nickel, gold and / or silver may be provided as a coating material on the plating, sputtering, vapor deposition or the like. Further, in the case of a substrate made of a resin material, it is preferable that the conductive pattern is easy to process. For example, in the case of a substrate made of an injection-molded resin, the conductive pattern is preferably one that is easily punched, etched, bent, or has a relatively large mechanical strength. Examples of specific conductive pattern materials include metals such as copper, aluminum, gold, silver, tungsten, rhodium, iron, nickel, and molybdenum, as well as iron-nickel alloys, phosphor bronze, and copper with iron. And so on.

FIG. 6 shows a diagram in which a part covered by the cover 112 is removed in order to explain the internal structure of the cover 112. In reality, the cover 112 covers the substrate 114 and the light source 115. The surface of the substrate 114 opposite to the light source arrangement surface comes into contact with the base plate 111.

The light sources 115 are evenly arranged on the substrate 114. For example, the light sources 115 are arranged in a matrix at pitch intervals of 15 mm or more and 20 mm or less. Each light source 115 includes a light emitting element 116, a wavelength conversion member 117, and a sealing member 118. The light emitting element 116 is mounted on the light source arrangement surface of the substrate 114, and the electrodes of the light emitting element 116 are electrically connected to the conductive pattern formed on the substrate 114. For example, the light emitting element 116 is covered with a wavelength conversion member 117 as shown in FIG.

The sealing member 118 has electrical insulation, is transparent to light emitted from a light source (for example, has a transmittance of 70% or more), and has fluidity before solidification (for example, before completion of curing). The material to have can be adopted. For example, a resin raw material may be included, and examples thereof include a silicone resin, an epoxy resin, a phenol resin, a polycarbonate resin, an acrylic resin, a TPX resin, a polynorbornene resin, or a modified resin or a hybrid resin thereof. Among them, a silicone resin is preferable because it has excellent heat resistance and / or light resistance (the "silicone resin" referred to in the present specification comprehensively includes a modified resin thereof or a resin having at least a silicone skeleton "silicone". Refers to "silicone resin"). Such a sealing raw material may additionally contain a filler and / or a phosphor or the like, if necessary.

The sealing member 118 covers the light emitting element 116 and the wavelength conversion member 117. The sealing member 118 has a shape having a recess near the center of the upper surface of the light emitting element 116. Further, the sealing member 118 has a shape having a plurality of protrusions around the recessed portion. As described above, the light source 115 has a butt-wing type light distribution characteristic due to the sealing member 118 having a flat shape as a whole and further having a recessed portion and a plurality of protrusions.

Further, at least the maximum thickness dimension of the sealing member 118 is smaller than the maximum width dimension. For example, the maximum width is more than twice the maximum thickness. The maximum thickness is the height from the substrate 114 to the top of the protrusion of the sealing member 118. With such a flat sealing member, the bat wing emits light from a lower height, and the thickness of the illuminating lamp 10 can be reduced. By reducing the thickness of the lighting fixture 10, it is possible to reduce the weight even if it has a large light emitting surface. The thickness of the lighting fixture 10 can be 30 mm or less.

The lighting fixture 10 can be, for example, a lighting fixture having a length of 450 mm, a width of 450 mm, a height of 20 mm from the ceiling installation surface to the light emitting surface, and a square light emitting surface. Further, the lighting fixture 10 may be a square lighting fixture having a light emitting surface of 600 mm in length and 600 mm in width. Further, instead of the square as shown in FIG. 6, for example, a rectangular lighting fixture having a light emitting surface of 150 mm in length and 600 mm in width can be used.

Based on the building standards of Japan, by designing the vertical and horizontal lengths by 600 mm or the length divided by the natural number, the compatibility with the ceiling material 40 will be improved. This is because, according to the building standards of Japan, building materials such as ceiling materials are treated in units of scale, and the length and width of the ceiling materials are also designed in units of about 300 mm.

By making the vertical width and the horizontal width of the lighting fixture 10 easy to match with the vertical width or the horizontal width of the ceiling material 40, for example, it becomes easy to install even when the lighting fixtures 10 are arranged side by side on the ceiling 4. The vertical or horizontal width of the lighting fixture 10 may be designed to have a length corresponding to the standard of the construction site (country) of the building 1 in which the lighting fixture 10 is installed. Therefore, the standard is not necessarily 300 mm. Not always.

The lighting fixture 10 that does not need to be fixed by the hanging material applies the load of the lighting fixture 10 to the ceiling material 40. Therefore, it is desirable to install the lighting fixture 10 of 1 on the ceiling material 40 of 1. Further, considering the balance of the load, it is preferable that the center of gravity of the lighting fixture 10 is located at the center of the ceiling material 40. By making the vertical or horizontal dimensions of the lighting fixture 10 correspond to the vertical and horizontal dimensions of the ceiling material in accordance with the standard of the building material, it becomes easy to design to satisfy these installation conditions.

FIG. 8 is a flow chart for explaining the process until the installation of the lighting fixture is changed. Further, FIGS. 9 to 18 are supplementary views for explaining each process, and are schematic views relating to the state of the living room. Of the work until the installation of the lighting fixtures is changed, the work that is not stated to be performed by a professional worker who can perform electrical work is a specialized work that can perform electrical work. It is a work that can be performed even if you are not a worker.

First, the work of removing the lighting fixture 99 installed on the ceiling 4 is performed (step S11). The lighting fixture 99 is installed on the ceiling 4 in a state of being connected to the hanging member 23 and connected to the electrical wiring 50. Therefore, in this step, the work of removing the lighting fixture 99 installed on the ceiling material 40 from the ceiling material 40, the work of removing the lighting fixture 99 from the hanging material 23, and the electrical wiring 50 of the lighting fixture 99 are used. The work of disconnecting the electrical connection is done.

In the work of removing the lighting fixture 99 installed on the ceiling material 40 from the ceiling material 40, at least the work of removing the lighting fixture 99 from the hanging material 23 and the work of disconnecting the electrical connection with the electric wiring 50 can be performed. The lighting fixture 99 is removed from the ceiling material 40 so as to be in the state. Therefore, the entire lighting fixture 99 may be removed, or only a part necessary for the work may be removed.

In the work of removing the lighting fixture 99 from the hanging material 23, for example, the lighting fixture 99 connected to the hanging material 23 in the ceiling space is removed from the hanging material. As a result, the lighting fixture 99 is released from the state of being fixed to the skeleton 6 via the hanging member 23. That is, this work can be said to be a work in which the hanging member 23 and the lighting fixture 99, which were in a connected state in the attic space, are not connected.

In the work of disconnecting the electrical connection of the lighting fixture 99 from the electrical wiring 50, for example, by cutting the electrical wiring 50 connected to the lighting fixture 99 with a tool, the electrical connection with the electrical wiring 50 is performed. Can be separated. In this case, since there is a risk of electric shock or the like on the exposed portion of the cut surface, it is performed by a professional worker who can perform electrical work. The cutting may be performed by a method other than cutting.

Although related to the next process, it is preferable that the electrical wiring 50 suppresses the loss of wiring length due to disconnection so that a state in which a sufficient wiring length is secured can be maintained. When cutting the electric wiring 50, it is preferable to cut the electric wiring 50 at a position close to the end of the electric wiring 50 on the lighting fixture 99 side. For example, the electric wiring 50 connected to the lighting fixture 99 is cut at a position several centimeters from the root.

If the electrical wiring 50 is connected to a power adapter provided in the attic space separately from the lighting fixture 99, cut it at a position several centimeters from the root of the electrical wiring 50 connected to the power adapter. To. In this case, the power adapter for the lighting fixture 99 is also collected together with the removed lighting fixture 99.

If a sufficient length is secured, the cutting position of the electric wiring 50 may be appropriately determined by the operator, but it does not have to be unnecessarily shortened and is within 20 cm from the end of the electric wiring 50 on the lighting fixture 99 side. It is preferable to cut at the position. As a result, the electric wiring 50 electrically connected to the lighting fixture 99 can be separated from the lighting fixture 99, and the lighting fixture 99 is not electrically connected to the external power source.

It should be noted that the work of removing the lighting fixture 99 from the hanging material 23 and the work of disconnecting the electrical connection with the electric wiring 50 may be appropriately determined which work should be performed first. Further, the work in this process can be performed by a worker existing in the living room space.

Next, an electrical wiring 51 with a connector is provided as an electrical wiring that is electrically connected to the lighting fixture 10 (step S12). For example, a worker existing in the living room space can provide the electric wiring 51 with a connector by attaching the connector 52 to the electric wiring 50 separated from the lighting fixture 99. However, since there is a risk of electric shock when the connector 52 is attached, this work is performed by a professional worker who can perform electrical work. Further, the connector 52 is provided at the end of the electric wiring 50 separated from the lighting fixture 99.

The connector 52 is an example of an electric shock prevention connection component provided to prevent an electric shock in the work of connecting an electric connection device such as a lighting fixture and an electric wiring. By using this electric shock prevention connection component, it is possible to electrically connect the electric connection device in a state where the safety against electric shock is ensured.

Since the safety against electric shock is ensured, the connection work of the electrical wiring 51 with a connector by the connector 52 can be performed even by a non-specialized worker involved in electrical work. If you comply with the laws of Japan at the time of filing, you do not have to be a qualified electrician.

Note that the method is not limited to the method of attaching the connector 52 to the electric wiring 50 separated from the lighting fixture 99, and a new electric wiring 51 with a connector can be provided. For example, if the number of lighting fixtures increases compared to before the installation change, a new electrical wiring is provided as described in the interior work in step S5, and a connector is attached to the electrical wiring 51 with a connector. Just do it.

Further, instead of disconnecting the electric wiring 50 connected to the lighting fixture 99 and continuing to use it, it is also possible to newly provide an electric wiring 51 with a connector and use it. That is, as a method of providing the electric wiring 51 with a connector, it may be appropriately determined whether to provide the electric wiring 50 already provided or to newly provide the electric wiring 51. A sufficient number of electrical wirings 51 with connectors for supplying electric power to the lighting fixture 10 installed on the ceiling 4 may be provided.

9 to 11 show a flow in which the electric wiring 50 connected to the lighting fixture 99 is separated and the electric wiring 51 with a connector is provided by using the electric wiring 50. Further, FIG. 12 further shows a state in which the ceiling material 40 on which the lighting fixture 99 is installed has been removed. Further, in FIG. 12, the electric wiring 51 with a connector corresponding to the increased lighting fixture 10 is not yet provided.

As shown in FIG. 11, the electric wiring 51 with a connector can be provided with the ceiling material 40 related to the lighting fixture 99 installed, but the electric wiring 51 with a connector can be provided after the ceiling material 40 is removed. .. Since the ceiling material 40 can be removed without a professional worker involved in electrical work, if the electrical wiring 50 connected to the lighting fixture 99 is used, the electrical wiring 50 should be disconnected and the connector should be disconnected. It can be said that it is more efficient for a professional worker to perform the attachment work in a series of steps.

On the other hand, when newly installing electrical wiring in the space behind the ceiling, it is easier to perform the work after removing the ceiling material 40. With the ceiling material 40 installed, that is, with the ceiling 4 in FIG. 1, workers invade the space behind the ceiling and work in this space, but considering the narrowness and darkness of the space, The work will be difficult.

For this reason, the work of using the existing electric wiring 50 and the work of newly providing the electric wiring may be performed on different schedules. A professional worker involved in electrical work performs the work of providing the electrical wiring 51 with a connector using the existing electrical wiring 50, and then another worker performs the work of removing the necessary ceiling material 40, and then the work is performed. A professional worker involved in electrical work performs a new work of providing an electrical wiring 51 with a connector.

Next, the ceiling material 40 is newly installed to reshape the ceiling 4 (step S13). Since the ceiling material 40 on which the lighting fixture 99 is installed has an opening that matches the lighting fixture 99 and does not match the lighting fixture 10, the ceiling material 40 as it is can be used for the installation of the lighting fixture 10. Can not. Therefore, the worker existing in the living room space removes the ceiling material 40 on which the removed lighting fixture 99 is installed. As shown in FIG. 12, even if the ceiling material 40 is removed, the field edge 30 remains as it is and is connected to the hanging material 21. Further, after removing the ceiling material 40, another ceiling material 40 is newly installed as shown in FIG. The newly installed ceiling material 40 is formed with an opening having a shape suitable for the installation of the lighting fixture 10.

It is also possible to use the installed ceiling material 40 without preparing another new ceiling material 40. For example, the opening of the ceiling material 40 can be repaired to form an opening that can be used for installing the lighting fixture 10. Further, if the lighting fixtures before and after the change can be installed with openings having the same shape, it is not necessary to repair the openings.

As shown in FIG. 13, the opening provided for installing the lighting fixture 10 is sufficiently small or very small compared to the size of the ceiling surface of the ceiling material 40 or the size of the light emitting surface of the lighting fixture 10. It is a small opening. In addition, in this specification, it is said that the opening is 1/3 or less with respect to the area to be compared, and it is said that it is very small when it is 1/5 or less.

The opening can be formed in a circular shape having a diameter of 10 cm or more and 15 cm or less. The shape of the opening does not have to be a strict circular shape. The shape may be other than circular, and the opening can be formed in a shape included in a square having a side of 15 cm.

Even if the maximum diameter of the opening exceeds 15 cm or is less than 10 cm, the lighting fixture 10 can be installed, but as will be described later, the size of the fastener to be hooked on the ceiling material 40 and the worker Considering the workability of passing the arm, it is desirable to secure a circle of about 10 cm.

Even if the ceiling material 40 does not have the lighting fixture 99 installed, if the lighting fixture 10 is installed on the ceiling material 40 due to the installation change, an opening having a shape suitable for the installation of the lighting fixture 10 is formed. To. An opening may be formed in the ceiling material 40 that has already been installed, or the opening may be formed in the ceiling material 40 that is newly installed by removing the ceiling material 40 that has already been installed.

Further, the ceiling material 40 in the place where the lighting fixture 10 is not installed may be removed and a new ceiling material 40 may be installed. In addition, all ceiling materials 40 in the living room may be renewed. When the ceiling 4 is formed by mixing the old ceiling material 40 and the new ceiling material 40, it is conceivable that even if the ceiling material 40 is of the same type, the color tone will be different. In order to unify the colors, it is advisable to renew all the ceiling materials 40 in the living room. Whether to replace a part or all may be decided as appropriate.

In this way, the unnecessary ceiling material 40 is removed and a new ceiling material 40 is installed, and the ceiling 4 is reformed. Further, this work can be performed by a worker existing in the living room space.

As shown in FIG. 13, when the ceiling material 40 is installed by the work of step S13 and the ceiling 4 is reformed, the required number of electrical wirings 51 with connectors are already arranged in the attic space. Further, as shown in FIG. 13, each electric wiring 51 with a connector is arranged near the opening of the ceiling material 40 in which the lighting fixture 10 to which the electric wiring 51 with the connector is connected is installed. It is desirable that the worker in the living room is placed in a position where he / she can grasp it through his / her arm through the opening.

Next, the lighting fixture 10 is installed on the ceiling 4 (step S14). The worker existing in the living room space installs the lighting fixture 10 carried into the living room on the ceiling 4. To install the lighting fixture 10 on the ceiling 4, the work of electrically connecting the lighting fixture 10 to an external power source by using the connector 52 of the electric wiring 51 with a connector and the electrically connected lighting fixture 10 are used. The work of installing on the ceiling material 40 and the work are performed.

A worker existing in the living room space passes his arm through the opening of the ceiling material 40, grasps the electric wiring 51 with a connector provided in the space behind the ceiling, and pulls the connector 52 of the electric wiring 51 with a connector into the living room space. Then, the connector can be connected in the living room space. As described above, this connection work can be performed even by a non-specialized worker involved in electrical work.

As shown in FIG. 14, the connector can be connected by inserting the connector 52 of the electric wiring 51 with a connector into the terminal block 61 of the power adapter 60. Further, by inserting the electric cable 62 of the power adapter 60 into the terminal block 13 of the lighting fixture 10, the lighting fixture 10 can be electrically connected. The electric cable 62 is provided with a connector 63, so that even a non-specialized worker involved in electrical work can perform the connection work.

Note that the work of connecting the electric wiring 51 with the connector and the power adapter 60 and the work of connecting the power adapter 60 and the lighting fixture 10 can be connected regardless of which comes first. If it is more difficult to connect the electric wiring 51 with a connector to the power adapter 60 while the power adapter 60 and the lighting fixture 10 are connected, first connect the electric wiring 51 with a connector and the power adapter 60. It is preferable to keep it.

Further, the power adapter 60 does not have to be separate from the lighting fixture 10, and the connector 52 of the electrical wiring 51 with a connector may be inserted into the lighting fixture 10 with a power adapter. In other words, the lighting fixture 10 may be electrically connected by directly connecting the connector 52 of the electrical wiring 51 with a connector to the lighting fixture 10.

Further, instead of the structure in which the electric cable 62 extends from the power adapter 60 and is inserted into the terminal block 13 of the lighting fixture 10, the electric cable extends from the lighting fixture 10 and is inserted into the terminal block 61 of the power adapter 60. It may be a structure.

As shown in FIG. 15, the power adapter 60 connected to the electrical wiring 51 with a connector is placed behind the ceiling (attic space) through the opening of the ceiling material 40 by a worker existing in the living room space. By this work, the electric wiring 51 with the connector also returns to the state of being arranged behind the ceiling. That is, the power adapter 60 is arranged behind the ceiling through an opening through which the connected electrical wiring 51 with a connector passes.

Instead of arranging the power adapter 60 behind the ceiling, it may be installed in the opening of the ceiling material 40. In this case, the power adapter 60 has a fastener for installation on the ceiling material 40. Further, the lighting fixture 10 has a fastener for connecting to the power adapter 60.

In this way, the work of electrically connecting the lighting fixture 10 to the external power source is performed by using the connector 52 of the electrical wiring 51 with a connector. As a result, the electrical wiring 51 with a connector arranged in the space behind the ceiling and the lighting fixture 10 can be electrically connected through the opening provided in the ceiling material 40.

In the work of installing the electrically connected lighting fixture 10 on the ceiling material 40, a worker existing in the living room space attaches the mounting portion 12 of the lighting fixture 10 to the opening of the ceiling material 40, and attaches the lighting fixture 10 to the ceiling. Install in 4.

The lighting fixture 10 has a mounting portion 12 and a lighting portion 11 that illuminates the living room space on the side surface to be installed on the ceiling 4. Further, the mounting portion 12 has the terminal block 13 described above for electrical connection and a fastener 14 for physical mounting.

A worker existing in the living room space passes the fastener 14 of the lighting fixture 10 electrically connected to the electrical wiring 51 with a connector through the opening of the ceiling material 40, and installs the lighting fixture 10 on the ceiling material 40. The illuminating lamp 10 is not connected to the hanging member 23, and the entire load of the illuminating lamp 10 is applied to the ceiling material 40 on which the illuminating lamp 10 is installed.

When the lighting fixture 10 is installed on the ceiling material 40, the mounting bracket 70 as shown in FIG. 16 can also be used. When the mounting bracket 70 is used, the mounting bracket 70 is installed in the opening of the ceiling material 40 before the lighting fixture 10 and the electrical wiring 51 with a connector are electrically connected.

Although the lighting fixture 10 can be installed directly on the ceiling material 40, it may be easier to work by using the mounting bracket 70. For example, if the fastener has elasticity and it is necessary to shrink the fastener when passing through the opening of the ceiling material 40, it will be difficult to work while holding a large lighting fixture. The mounting bracket 70 can be said to be an example of a mounting auxiliary component that assists the mounting work of the lighting fixture 10 on the ceiling 4.

When using the mounting bracket 70, for example, after arranging the power adapter 60 connected to the electrical wiring 51 with a connector in the space behind the ceiling, the fastener 71 of the mounting bracket 70 is installed through the opening of the ceiling material 40. After installing the mounting bracket 70 on the ceiling material 40, the electric cable 62 of the power adapter 60 is pulled into the living room space and connected to the lighting fixture 10. Then, in a state where the lighting fixture 10 is electrically connected to the electric wiring 51 with a connector, the fastener 14 of the lighting fixture 10 is installed through the opening of the mounting bracket 70.

FIG. 17 shows the connection relationship between the lighting fixture 10, the power adapter 60, and the mounting bracket 70. As shown in FIG. 17, the electric cable 62 of the power adapter 60 is connected to the terminal block 13 of the lighting fixture 10, and the fastener 14 of the lighting fixture 10 is fitted into the mounting bracket 70.

If the power adapter 60 can pass through the opening of the mounting bracket 70, the mounting bracket 70 can be installed on the ceiling material 40, and then the electrical wiring 51 with a connector and the power adapter 60 can be connected. However, if the attachment of the mounting bracket 70 makes the opening connecting the living room space and the attic space smaller, making it difficult to grab the electrical wiring 51 with a connector and pull it into the living room space, this procedure is performed. It is preferable to avoid it.

In this way, the worker existing in the living room space has the lighting fixture 10 which is not connected to the hanging member 23 and is electrically connected to the electric wiring 51 with the connector. It can be installed in the opening of the ceiling material 40 by using the fastener 14.

As described above, in the building 1, the lighting of the living room can be replaced from the lighting lamp 99 to the lighting lamp 10. Further, by performing the replacement work in such a procedure, the work can be simplified. In addition, the workers can be effectively utilized.

One is that it is not necessary to prepare a hanging material 23 for the newly installed lighting fixture 10. In other words, when a hanging material is required for a newly installed lighting fixture, if the hanging material provided before installation cannot be used as it is, it is necessary to suspend the new hanging material from the skeleton. It is not necessary in the installation process described in the first embodiment.

Another point is that the work after reforming the ceiling 4, that is, the installation work of the lighting fixture 10, does not require a specialized worker involved in electrical work. If a professional worker involved in electrical work disconnects the electrical wiring 50 connected to the lighting fixture 99 in the first half and provides the electrical wiring 51 with a connector, the subsequent work can be done by other workers. Therefore, it is possible to shorten the work time for restraining a professionally qualified person.

In addition, since it is not necessary to connect the lighting fixture 10 with the hanging material 23, the ceiling material 40 should be provided with an opening capable of pulling out the electrical wiring 51 with a connector arranged in the attic space into the living room space. There is a point where you can work. Since it is sufficient that the lighting fixture 10 is installed on the ceiling 4 with an opening having a size through which an arm can pass, the work of forming the opening in the ceiling material 40 is also simplified. It should be noted that each of these advantages can be enjoyed without necessarily having all the processes described in the first embodiment.

In the living room after the installation change shown in Fig. 4, the lighting fixtures were only changed when viewed from the living room space side, but on the other hand, due to the installation of lightweight large lighting fixtures that do not need to be directly connected by hanging materials. , The attic space will have a characteristic structure.

Specifically, in the attic space, the hanging material 23 remains in a state where it is not connected to the lighting fixture 10. Alternatively, the hanging member 23 has been removed, but the insert embedded in the skeleton 6 remains. By installing the lighting fixture 10 in the place where the lighting fixture 99 was installed, the following structure is formed in the building 1.

A ceiling 4 formed by arranging a plurality of ceiling materials 40, a lighting fixture 10 installed through an opening of the ceiling material 40, and a ceiling material in which the lighting fixture 10 is installed in a top view in the space behind the ceiling. Building 1 which has an insert or a hanging material 23 arranged in an area surrounded by an outer frame of 40, and the lighting fixture 10 is not connected to the hanging material 23. The insert may or may not be connected to the hanging member 23.

The state in which the insert and the hanging member 23 are not connected is created by, for example, removing the lighting fixture 99 from the hanging member 23, disconnecting the electrical wiring 50, and then removing the hanging member 23 from which the lighting fixture 99 has been removed from the insert. be able to. Further, the suspension member 23 may be removed from the insert before or after the electrical wiring 51 with the connector is provided, but it is preferable to remove the suspension member 23 before the ceiling is reformed.

By removing the hanging material 23 that is no longer needed, unnecessary items can be removed from the space behind the ceiling. On the other hand, by leaving the hanging material 23, it is not necessary to increase the work man-hours of the worker, and the work can be completed promptly.

<Second embodiment>
Next, the installation process of the lighting fixture in the building according to the second embodiment will be described. The installation process according to the second embodiment is different from that of the first embodiment when the lighting fixtures are installed in a place where they were not installed before the installation change, or when the number of installed lamps is increased compared to before the installation change. Have a procedure.

In the first embodiment, in these cases, the electric wiring 50 already connected to the lighting fixture 99 is not sufficient, so a new electric wiring 51 with a connector is provided. In the second embodiment, the work load of a professional worker involved in the electrical work can be reduced by taking measures without performing the wiring work that increases the number of electrical wirings drawn from the pipes.

FIG. 18 is a schematic diagram for explaining a corresponding method without performing wiring work. As is clear from the figure, in the second embodiment, the power adapter 260 having two or more electric cables 62 is used.

When a new lighting fixture 10 is installed in a place where the electrical connection device such as the lighting fixture 10 was not installed before the installation change and the electric wiring 50 did not need to be arranged, the lighting fixture 10 is installed near the lighting fixture 10. The power adapter 260 is arranged in.

For example, as shown in FIG. 18, if the ceiling material 40 in which the electrical connection device is not installed and the ceiling material 40 in which the electrical connection device is installed are adjacent to each other before the installation change, the ceiling material 40 is installed. It is advisable to use the electrical wiring 50 used for the electrical connection of the electrical connection device and the power adapter 260 to electrically connect the newly installed lighting fixture 10.

If the electrical wiring 50 provided before the installation change can be covered, a professional worker involved in electrical work can simply change the electrical wiring 50 to the electrical wiring 51 with a connector, which is necessary for the installation change. Electrical wiring can be prepared.

In the work of installing the lighting fixtures in step S14, the number of workers existing in the living room space includes the number of electrical wirings 51 with connectors arranged in the attic space and the number of lighting fixtures 10 installed on the ceiling. Based on this, the required number of

power adapters

60 and 260 are prepared.

Here, in order to distinguish between the power adapter 60 and the power adapter 260, the power adapter 60 is referred to as a first power adapter, the power adapter 260 is referred to as a second power adapter, and these are not distinguished when they are simply referred to as a power adapter. To do.

Depending on the situation, the prepared power adapters may all be the first power adapter or all may be the second power adapter. Here, it is assumed that both the first power adapter and the second power adapter are prepared.

When the required number of power adapters are prepared, the worker existing in the living room space connects the electric wiring 51 with the connector to the power adapter in the same manner as the work performed in the first embodiment. Typically, the number of power adapters provided for the luminaire 10 is equal to or less than the number of connector-equipped electrical wiring 51 arranged in the attic space.

The worker places the power adapter connected to the electrical wiring 51 with a connector behind the ceiling. For each power adapter, the connector 63 of the electrical cable 62 of the power adapter is preferably located in an opening near the power adapter.

When arranging the second power adapter, one of the plurality of electric cables 62 has the connector 63 arranged in the opening near the second power adapter, but the connector 63 of the remaining electric cables 62. Is preferably placed near the opening of another ceiling member 40.

Although the power adapter 260 having two electric cables 62 is shown in the example of FIG. 18, the number of electric cables 62 that can be provided in one power adapter 260 may be three or more. However, in order to avoid concentrating the load of electric control in one place, it is preferable that the number of electric cables 62 is 4 or less.

Next, the worker existing in the living room space connects the terminal block 13 of the lighting fixture 10 and the electric cable 62 of the power adapter. When the second power adapter is used, different lighting fixtures 10 are connected to each of the plurality of electric cables 262 of the second power adapter. The lighting fixture 10 electrically connected to the electrical wiring 51 with a connector is installed on the ceiling material 40 as in the first embodiment.

While using the second power adapter, it is also possible to electrically connect to one lighting fixture 10 with one electric cable 262 without using a plurality of electric cables 262. That is, it is not always necessary to use all of the plurality of electric cables 262.

In the building 1 according to the second embodiment, in a plurality of power adapters arranged for electrical connection of the plurality of lighting fixtures 10, a power adapter for connecting to at least a plurality of lighting fixtures 10 is used. Further, the first power adapter or the second power adapter may be used as the power adapter to be connected to one lighting fixture 10.

In this way, by using the power adapter 260 having a plurality of electric cables 62, it is possible to eliminate the work of newly providing the electric wiring 51 with a connector, and the workload of a professional worker involved in the electric work can be reduced. It can be mitigated.

<Third Embodiment>
Next, the installation process of the lighting fixture in the building according to the third embodiment will be described. FIG. 19 is a schematic view showing a living room in a state after the lighting installation is changed in the building 1. The living room of the building 1 shown in FIG. 19 is different from the one shown in FIG. 4 in the lighting fixtures. Specifically, the lighting lamp is changed from the lighting lamp 10 to the lighting lamp 310.

Except for the difference in the shape of the lighting fixture, the process of changing the installation from the state shown in FIG. 1 to the state shown in FIG. 19 is the same as the content described in the first embodiment, and thus the description thereof will be omitted. .. Therefore, here, an installation process in the case of changing the installation from the state of FIG. 4 to the state of FIG. 19 will be described as an example. FIG. 20 is a flow chart for explaining a process until the installation of the lighting fixture is changed.

In the case of a ceiling-embedded lighting fixture, it is necessary to match the shape of the opening provided in the ceiling material 40 with the shape of the light emitting surface of the lighting fixture. Therefore, replacement with a lighting fixture having a different light emitting surface shape is a new ceiling material. 40 is required. Therefore, it was necessary to remove not only the lighting fixtures but also the installed ceiling material 40 and replace them with new ones.

On the other hand, the lighting fixture 10 does not need to match the opening of the ceiling material 40 with the shape of the light emitting surface, and can be installed with an opening sufficiently smaller than the light emitting surface. In the example described in the first embodiment, the opening was 10 cm or more and 15 cm or less, and the light emitting surface was 450 mm in length and 450 mm in width. Further, in addition to such a shape, it was explained that a rectangular lighting fixture having a length of 150 mm and a width of 600 mm can be used as the lighting fixture to be attached.

The lighting fixture 310 of the third embodiment can be, for example, the lighting fixture having the rectangular light emitting surface of 150 mm in length and 600 mm in width described above. The illuminating lamp 310 has the same mounting portion 12 as the illuminating lamp 10. Further, the lighting fixture 310 is also a lightweight large-sized lighting fixture like the lighting fixture 10, and is a lighting fixture that does not need to be connected to a hanging material when installed on the ceiling 4.

Since the opening formed for the illuminating lamp 10 has a size that does not exceed either the vertical width or the horizontal width of the illuminating lamp 310, the mounting portion 12 is provided so as not to exceed either the vertical width or the horizontal width of the illuminating lamp 310. Can be done. By providing the mounting portion 12 at such a position, the lighting fixture 310 installed on the ceiling 4 does not protrude from the light emitting surface when the ceiling 4 is looked up from the floor 2 side of the living room.

In the case of conventional large lighting fixtures, it is necessary to connect them to the hanging material 23 when installing them on the ceiling 4, and between the lighting fixtures 10 and the large lighting fixtures whose light emitting surfaces have significantly different shapes such as the light emitting surfaces of the lighting fixtures 310. Then, the connection position of the hanging member 23 was different. Then, it was difficult to use the same ceiling material 40 even if the same mounting portion 12 was provided.

On the other hand, the lighting fixture 10 and the lighting fixture 310, which are lightweight and large lighting fixtures, are realized, and by commonly adopting the mounting portion 12 designed to have a size that does not exceed the vertical width and the horizontal width of any of the lighting fixtures. The opening formed in the ceiling material 40 for the installation of one of the lighting fixtures can be used as it is, and the other lighting fixture can be installed in the ceiling material 40.

Here, in the example described in the third embodiment, it is assumed that the illuminating lamp 10 and the illuminating lamp 310 are manufactured by the same manufacturer. By standardizing the mounting portion used for the lightweight and large lighting fixture, even if the lighting fixture 10 and the lighting fixture 310 are manufactured by different manufacturers, they can be replaced by using the same opening.

Also, the mounting portions used between different lighting fixtures do not have to have exactly the same shape. Since it is sufficient that the ceiling 4 can be installed using the same opening, for example, the mounting portions may have the same shape in the plane direction but different shapes in the height direction. Also, slight differences in the shape in the plane direction will be tolerated.

Further, when a mounting auxiliary component such as the mounting bracket 70 described in the first embodiment is used, the degree of freedom in the shape of the mounting portion will be further increased. This is because if the mounting auxiliary part is designed to fit the opening of the ceiling material, the opening of the mounting auxiliary part can be designed to have a shape corresponding to each of the different lighting fixtures. Compared to the removal of the ceiling material, the mounting bracket can be replaced more easily.

As described above, having the same mounting portion 12 means having a mounting portion to be mounted using the same opening, and if this is achieved, mounting portions having different shapes are also included. ..

The replacement between the luminaire 10 and the luminaire 310, which are lightweight and large luminaires having the same mounting portion 12, is a very simple and easy procedure as shown in the flow chart of FIG.

First, the lighting fixture 10 installed on the ceiling 4 is removed (step S31). The worker existing in the living room space removes only the lighting fixture 10 while leaving the ceiling material 40 as it is. Further, the lighting fixture 10 and the electric wiring 51 with a connector are not electrically connected. Specifically, the connector of the electric cable 62 inserted in the terminal block 13 is unplugged.

Also, the power adapter 60 and the electrical wiring 51 with a connector are not electrically connected. Specifically, the connector of the electric wiring 51 with a connector inserted in the terminal block 61 is pulled out. In addition, the power adapter 60 arranged in the space behind the ceiling is collected.

In order to facilitate the work of disconnecting the connector of the electric wiring 51 with a connector inserted in the terminal block 61, it is preferable to remove the mounting bracket 70 installed on the ceiling material 40 first. Further, when the power adapter 60 can be used as it is for the lighting fixture 310, the work of making the lighting fixture 10 and the electric wiring 51 with a connector not electrically connected may be performed.

Next, the lighting fixture 310 is installed on the ceiling 4 (step S32). This step is the same as step S14 of the first embodiment. If the power adapter 60 can be used as it is, the work starts from the place shown in FIG. Therefore, a worker existing in the living room space electrically connects the lighting fixture 310 and the electric wiring 51 with a connector, and installs the lighting fixture 310 on the ceiling material 40 in the electrically connected state. Just do.

In this way, a lightweight and large lighting fixture is realized, and by making it possible to use the same mounting part and the same power adapter, the replacement work is simplified and becomes very simple. Further, even if different power adapters are used, the replacement work can be simplified as long as they can be connected to the connector of the electric wiring 51 with a connector.

Although it is possible to install it on the ceiling 4 using the same opening, there may be cases where the electrical connection work is different. For example, it is a case of replacing with a lighting fixture that can be connected to an electric wiring without a connector. In such a case, a professional worker involved in electrical work performs the work of electrically connecting the lighting fixture and the electrical wiring. Even in such a case, since it is not necessary to newly provide a hanging material, the replacement work is simplified.

<Fourth Embodiment>
Next, the installation process of the lighting fixture in the building according to the fourth embodiment will be described. FIG. 22 is a schematic view showing a living room in a state after the lighting installation is changed in the building 1. The living room of the building 1 shown in FIG. 22 has the same lighting fixtures installed on the ceiling as those shown in FIG. 19, but the layout is different. Specifically, regarding the connecting direction of the lighting fixture, assuming that the connecting direction of FIG. 19 is the horizontal direction, the connecting direction of FIG. 22 is the vertical direction.

In the fourth embodiment, the installation process when the installation is changed from the state shown in FIG. 19 to the state shown in FIG. 22 will be described as an example. When changing the installation from FIG. 19 to FIG. 22, the following three patterns can be mentioned as the change pattern when looking at the 40 units of the ceiling material provided on the ceiling 4.

The first is the pattern that the lighting fixtures were installed before the change at the position of the ceiling material, but they will not be installed after the change. Next, the second pattern is that, at the position of the ceiling material, the lighting fixture was not installed before the change, but it is installed after the change. The third pattern is that, at the position of the ceiling material, the same lighting fixtures as before the change are installed after the change, but the direction in which they are installed changes.

In addition to this, there may be patterns that do not change the installation. As a pattern in which the installation is not changed, there may be a pattern in which the lighting fixture is not installed before and after the installation change, or a pattern in which the lighting fixture is still installed in the same position and orientation before and after the installation change.

FIG. 23 is a flow chart for explaining the process of the first change pattern. Further, FIG. 24 is a flow chart for explaining the process of the second change pattern. Further, FIG. 25 is a flow chart for explaining the process of the third change pattern.

As shown in the flow chart of FIG. 23, in the first change pattern, first, the lighting fixture 310 is removed (step S411). The worker existing in the living room space removes only the lighting fixture 310 while leaving the ceiling material 40 as it is. Further, the lighting fixture 10 and the electric wiring 51 with a connector are not electrically connected. Specifically, the connector 63 of the electric cable 62 inserted in the terminal block 13 is pulled out.

Further, as described in step S31 of the third embodiment, the mounting bracket 70 installed on the ceiling material 40 is removed, and the power adapter 60 arranged in the space behind the ceiling is collected. It is not essential to collect the power adapter 60 and the mounting bracket 70. For example, the power adapter 60 may be left in the attic space only by moving the arranged position, and the power adapter 60 may be used for the lighting fixture 310 installed at another position.

Next, a new ceiling material 40 is installed on the ceiling 4 (step S412). Since the ceiling material 40 that has been installed has an opening for installing the lighting fixture 310, the ceiling material 40 is placed in a closed state. Therefore, the worker existing in the living room space removes the installed ceiling material 40 and installs another ceiling material 40 having a closed opening. Instead of replacing the ceiling material, a replenishing member that closes the opening may be attached to the ceiling material 40.

As shown in the flow chart of FIG. 24, in the second change pattern, the ceiling material 40 is first removed (step S421). Next, an electrical wiring 51 with a connector for electrically connecting to the lighting fixture 310 is prepared. As a method of preparing the electrical wiring 51 with a connector, there is a method in which a professional worker involved in the electrical work performs the wiring work and newly provides the electrical wiring 51 with a connector. In addition to this, there is a method of using the already provided electric wiring 51 with a connector.

As the electrical wiring 51 with a connector that has already been provided, it is conceivable to use the electrical wiring 51 with a connector that remains after the lighting fixture 310 is removed, as in the first change pattern. Alternatively, as described in the second embodiment, it is conceivable to use the electric wiring 51 with a connector connected to the power adapter 60. In this case, the work of replacing the power adapter 60 with the power adapter 260 is performed.

When the lighting fixture 310 is provided near the already provided electric wiring 51 with a connector, it is preferable to use the electric wiring 51 with a connector. Further, when the on / off of the lighting by the switch is controlled in a predetermined area, it is desirable to use the electric wiring 51 with a connector in the same area.

For example, when the control is performed in the dotted line area A of FIG. 19, the electric wiring 51 with a connector that electrically connects to the lighting fixture 310 installed in this area is installed in the dotted line area of FIG. 23. It is preferably used for electrical connection of the luminaire 310.

When the electrical wiring 51 with a connector is prepared (step S422), then the ceiling material 40 is installed (step S423), and then the lighting fixture 310 is installed (step S424). The installation of the ceiling material 40 and the installation of the lighting fixture 310 can be performed by the same operations as those described in steps S13 and S14. Further, the lighting fixture 310 can be installed by the method described in the second embodiment.

As shown in the flow chart of FIG. 25, in the third change pattern, first, the fixed state of the lighting fixture 310 installed and fixed on the ceiling material is released (step S431). For example, a worker existing in a living room space removes only the lighting fixture 310 while leaving the ceiling material 40 as it is. Further, the lighting fixture 310 and the electric wiring 51 with a connector are maintained in a state of being electrically connected.

Next, the lighting fixture 310 is rotated (step S432). A worker existing in the living room space rotates the lighting fixture 310 at a desired angle on a plane parallel to the ceiling surface according to the direction of installation on the ceiling 4. In the example of the fourth embodiment, as shown in FIG. 26, the lighting fixture 310 is rotated by 90 degrees in a plane parallel to the ceiling surface.

This rotation work can be performed with the electric cable 62 inserted into the terminal block 13 of the lighting fixture 310. The electric cable 62 may be once pulled out from the terminal block 13, the lighting fixture 310 may be rotated, and the electric cable 62 may be inserted into the terminal block 13 again.

Next, the lighting fixture 310 is installed (step S433). The worker present in the living room space is the lighting fixture 310 whose fixed state is released in step S431, and the lighting fixture 310 rotated in step S432 can be used as it is and installed on the ceiling material 40. Since the electrical connection has already been completed, it is only necessary to install the lighting fixture 310 on the ceiling material 40.

In this way, once the living room in which the lighting fixture 10 and the lighting fixture 310 are installed is completed in the building 1, the layout of the lighting in the living room can be easily changed. Since it is not necessary to connect to the hanging material 23, it is not necessary to provide an opening in the ceiling material 40 according to the connection position of the hanging material determined in consideration of the shape and balance of the lighting fixture, and the installation of the lighting fixture is changed with a unified opening. Can be done.

This eliminates the image of large-scale work like before for changing the layout of lighting. Since the work man-hours are reduced, costs such as labor costs and material costs are reduced. For example, when there is a change in the tenant who uses the living room of the building 1, it becomes easy to propose a change in the lighting layout to the tenant.

Regarding changes between the

lighting fixtures

10 or 310, such as the installation change from the lighting fixture 10 to the lighting fixture 310 and the arrangement change of the lighting fixture 10 and the lighting fixture 310, in the building 1 at the stage before the change. , There may be no hanging member 23 in the space behind the ceiling of the living room. That is, at the time of construction of the building 1, the lighting fixture 10 and the lighting fixture 310 are installed in the living room, and the installation of the lighting fixtures 10 is changed. At this time, since the illuminating lamp 10 or the illuminating lamp 310 is installed at the construction stage, it is not necessary to provide the hanging member 23 at the time of construction.

As shown in the examples of FIGS. 19 and 22, the layout can be designed so that a plurality of lighting fixtures 310 are connected and installed, so that the lighting can be designed as an integrated lighting. Here, in order to explain some modes of changing the connected state, each mode will be captured in a region of the ceiling material 40 provided in a 2 × 2 matrix. In FIGS. 19 and 22, a region B, a region C, and a region D are shown. For example, looking at the area B of the broken line, the layout change from FIG. 19 to FIG. 22 can be expressed as follows.

It is installed on the ceiling material 40 so that one side of the outer shape of the quadrangle intersecting with this one side (hereinafter referred to as the second direction) is parallel to the ceiling material 40, and a plurality of lighting fixtures 310 are connected to each other. This is a method of changing the installation to the state where it is installed. In addition, the process is composed of a third change pattern.

Specifically, one of the two lighting fixtures 310 that are adjacent to each other and connected in the first direction, and the lighting fixture 310 that is installed closest to the lighting fixture 310 in the second direction, respectively. On the other hand, the fixed state is released, rotated 90 degrees on a plane parallel to the ceiling surface, and installed and connected to the ceiling material 40 installed immediately before the fixed state is released. Further, the same operation is performed for each of the other illuminating lamp 310 of the two illuminating lamps 310 and the illuminating lamp 310 installed closest to the illuminating lamp 310 in the second direction.

Looking at the dotted line area C, for example, changing the layout from FIG. 19 to FIG. 22 is a method of changing the connected state in the same manner as in the area B. Further, the process is composed of a first change pattern and a third change pattern.

Specifically, one of the two lighting fixtures 310 that are adjacent to each other and connected in the first direction, and the lighting fixture 310 that is installed closest to the lighting fixture 310 in the second direction, respectively. On the other hand, the fixed state is released, rotated 90 degrees on a plane parallel to the ceiling surface, and installed and connected to the ceiling material 40 installed immediately before the fixed state is released. Further, each of the other lighting fixture 310 of the two lighting fixtures 310 and the lighting fixture 310 installed closest to the lighting fixture 310 in the second direction is removed from the ceiling material 40 and installed. A ceiling material 40 without an opening is installed at the ceiling position.

Looking at the broken line area D, for example, changing the layout from FIG. 19 to FIG. 22 is a method of changing the connected state in the same manner as in the area B. Further, the process is composed of a first change pattern, a second change pattern, and a third change pattern.

Specifically, one of the two lighting fixtures 310 adjacent to each other in the first direction is removed from the ceiling material 40, and the ceiling material 40 without an opening is installed at the ceiling position where the lighting fixture 310 is installed. To do. Further, the other lighting fixture 310 of the two lighting fixtures 310 is released from the fixed state and rotated by 90 degrees on a plane parallel to the ceiling surface to the ceiling material 40 installed immediately before the fixed state is released. And install. Further, the ceiling material 40 at the position where the lighting fixture 310 connected to the other lighting fixture 310 in the second direction is installed is removed, the electric wiring 51 with a connector is prepared, and the ceiling material 40 having an opening is installed. The lighting fixture 310 electrically connected to the electrical wiring 51 with a connector is installed on the ceiling material 40 with the long side parallel to the second direction.
