[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes embodiments of the present invention with reference to the drawings. However, the embodiments described below are intended to embody the technical concept of the present invention and are not intended to limit the present invention. Furthermore, in the following description, the same names and symbols indicate the same or similar components, and detailed descriptions will be omitted as appropriate. Note that the size and positional relationship of components shown in each drawing may be exaggerated for clarity.

[0014] Figure 1 is a flow diagram that explains the process flow until a building is constructed. Here, we focus on a multi-story building with corridors and rooms, such as a typical office building. In the construction of a large-scale building such as an office building, a general construction company is contracted to place an order for the construction work and coordinates the entire construction work carried out by various contractors.

[0015] First, architects and designers design the building (Step S1). In this process, the layout of corridors and rooms is decided, and the overall design of the building is recorded on blueprints. The building materials to be used, electrical equipment such as lighting fixtures, and air conditioning equipment are also decided to some extent, and their placement is also recorded on the blueprints.

[0016] Next, based on the determined design, building materials and construction machinery are prepared, and foundation work is carried out (step S2). In this process, pile work and earthworks are carried out to ensure a stable foundation that can withstand the load of the building. This work is mainly carried out by workers from civil engineering contractors. Note that this work is not limited to civil engineering contractors, but also involves workers from other contractors.

[0017] Next, structural work is carried out to form the building's framework on stable ground (Step S3). Structural work begins with the foundations and, if there is a basement, the basement floor, and then proceeds to the aboveground floors. The framework of the entire building is completed by pouring concrete, erecting columns, assembling steel frames, etc. Concrete is also poured for the exterior walls, roof, floors of each floor, etc.

[0018] Furthermore, during the framework construction, inserts are embedded to suspend suspension materials such as suspension bolts during the subsequent interior construction work. For example, ceiling inserts for fixing suspension bolts are fixed as part of the floor slab (such as reinforced concrete floor panels) on the upper floor when the slab is poured. This work is mainly carried out by workers from civil engineering contractors and workers from scaffolding, earthwork, and concrete contractors. Next, the exterior construction of the building is carried out (Step S4). This involves tiling the exterior walls, and installing window sashes, window glass, curtain walls, etc. Painting and other work are also carried out.

[0019] Next, interior construction work is carried out (Step S5). In the interior construction work, the ceiling, walls, and floors are constructed. In the ceiling construction work to install the ceiling, suspension bolts are lowered from the ceiling inserts installed in the framework work in Step S3, and ceiling materials, which are the components that make up the ceiling surface, such as ceiling panels and ceiling underlayment materials, are attached to the base combined with lightweight steel frames. The ceiling materials are supported by suspension materials such as suspension bolts and hangers, as well as diagonal members, and this is an anti-hazard measure to prevent danger such as the ceiling panels falling off.

[0020] For example, in Japan, regulations to prevent ceilings from falling off are established in the Building Standards Act and enforcement ordinances. One of these regulations requires that when installing ceiling materials that meet certain conditions, measures to prevent falling off, such as fixing them with hanging materials, be taken. For example, air conditioning equipment is heavy, so measures to prevent falling off are necessary. In addition, lighting fixtures, such as conventional so-called base lighting, which are large and heavy, also need to be fixed with hanging materials.

[0021] It is possible to install ceiling inserts for fixing the suspension bolts by driving anchors into the concrete after the concrete has been poured, instead of installing them when the concrete is poured. However, considering efficiency and safety, it is preferable to install them beforehand, and for locations where it is known that suspension materials will be installed, it is desirable to determine the placement of the ceiling inserts at the design stage and embed them when the concrete is poured.

[0022] Furthermore, during interior construction work, before the ceiling is laid, i.e., before the ceiling is completely constructed with ceiling materials, pipes and air conditioning ducts are hung and electrical wires are routed through the pipes. Therefore, the space required for installing electrical wiring, ducts, air conditioning equipment, etc. is provided above the ceiling. Furthermore, openings are provided in the ceiling material to accommodate the locations where lighting and air conditioning will be installed. Work such as installing ducts within the ceiling and securing the ceiling material with hanging materials is performed by workers from the interior construction contractor. On the other hand, installing electrical wiring involves the risk of electric shock, so it is performed by specialized workers who are skilled in electrical work.

[0023] It is assumed that in many cases, the workers who install the ceiling and the workers who run the electrical wiring in the attic are different people. In Japan, it is not permitted for anyone without a license to be an electrician to carry out electrical work such as wiring. In this way, safety is taken into consideration when constructing a building, as workers are dispatched from various specialized contractors and each one performs their own specialized work.

[0024] In this specification, a contractor's worker who prepares ceiling materials for the construction of a building and performs ceiling work is called a ceiling installation worker. Also, a contractor's worker who prepares electrical wiring for the construction of a building and performs wiring work is called a wiring worker. Note that each step in the construction of a building is usually performed by multiple workers. Therefore, a ceiling installation worker is not limited to a single worker, but refers to one or more workers who perform ceiling work in the construction of a building. The same applies to wiring workers, etc.

[0025] Next, once the interior construction work is complete and the floors, walls, and ceilings are finished, installation work begins (Step S6). During installation work, the facilities required for the actual use of the building are installed. For example, facilities for electricity, gas, water, drainage, air conditioning, toilets, disaster prevention, broadcasting, etc., as well as lighting, escalators, elevators, etc. are installed. These tasks are carried out by workers from businesses such as electrical contractors, telecommunications contractors, waterworks contractors, firefighting contractors, and cleaning facility contractors.

[0026] When installing lighting or air conditioning, these devices must be electrically connected, so work must be done by a qualified electrician. Lighting can be installed in places other than the ceiling, but ceiling-mounted lighting fixtures are usually electrically connected by being connected to wiring prepared in the attic by a qualified electrician. When installing air conditioning equipment in the ceiling, the equipment is also connected to wiring prepared in the attic by a qualified electrician.

[0027] Typically, in rooms of buildings such as office buildings, large lighting fixtures and air conditioning units installed on the ceiling are fixed by hanging members, so workers who install such large lighting fixtures and air conditioning units also install them on the ceiling by fixing them to hanging members suspended from ceiling inserts.

[0028] It is not uncommon for lighting installation work and air conditioning installation work to be carried out separately. Lighting fixture manufacturers manufacture the lighting fixtures needed for construction in time for the lighting installation work. Similarly, air conditioning equipment manufacturers manufacture the air conditioning equipment needed for construction in time for the air conditioning installation work. In this specification, companies that manufacture and provide lighting fixtures will be called lighting fixture suppliers, and companies that manufacture and provide air conditioning equipment will be called air conditioning equipment providers.

[0029] First Embodiment Next, the construction process of a building according to the first embodiment will be described. The building 1 according to the first embodiment has a multi-story structure and includes corridors and rooms. However, it may also be a single-story building. Figure 2 is a schematic diagram showing an example of the structure of a room on a specific floor of the building 1.

[0030] Building 1 forms a living space with floor 2, walls 3, ceiling 4, and windows 5. Note that the living space may not have windows 5 and only have walls 3 on the sides. In addition, a plurality of lighting fixtures 10 and a plurality of air conditioning units 90 are installed on the ceiling.

[0031] For example, in buildings such as office buildings, small ceiling-mounted fixtures such as downlights are installed to illuminate narrow spaces such as corridors, while large lighting fixtures such as base lights are mainly installed in large spaces such as living rooms. In such cases, it is typical that many large lighting fixtures 10 are installed in living rooms, and small lighting fixtures are not installed or are installed in only a small area of ​​the room. Also, it is typical that the number of lighting fixtures 10 installed in living rooms is greater than the number of air conditioners 90 installed.

[0032] In a room, the lighting fixtures 10 and air conditioners 90 are arranged in a regular pattern. In the example of Fig. 2, one air conditioner 90 is sandwiched between three lighting fixtures 10 facing each other, which can be considered as one regular set. In the room, the lighting fixtures 10 and air conditioners 90 are installed in an arrangement similar to a matrix of sets. In an office, there are rows of desks where employees work, and it is preferable to arrange the lighting fixtures 10 and air conditioners 90 in a regular pattern so that there is not much difference in the environment depending on the location.

[0033] In the example of Figure 2, the ceiling 4 is divided into four imaginary areas by dashed lines. There are four areas that form sets in this way, and for convenience, these will be referred to as Area A, Area B, Area C, and Area D. Note that not all areas need to be configured as the same set, i.e., with the same arrangement structure. Also, they do not necessarily need to be configured with only a regular arrangement. The ceiling 4 has multiple areas that surround one air conditioning unit 90 installed on the ceiling 4 and multiple lighting fixtures 10 installed around the air conditioning unit 90.

[0034] The lighting fixture 10 shown in Fig. 2 has performance equivalent to that of base lighting, but does not require fixing with a hanger during lighting installation work. In other words, the lighting fixture 10 is a lightweight large lighting fixture that is large enough to be handled as equivalent to base lighting, but light enough not to require a hanger.

[0035] Here, in this specification, a lightweight large-sized lighting fixture is one that has a total luminous flux of 2500 lm or more, or has an area of ​​the light-emitting surface closest to the floor of 45,000 mm 2 The term "lightweight large-sized lighting fixture" refers to a lighting fixture that satisfies at least one of the following conditions: the light source element is 100 or more, or the light source element is 100 or more. Alternatively, the characteristics of a lightweight large-sized lighting fixture may be further specified by the condition that the weight is 0.5 kg or more but less than 2.5 kg.

[0036] Next, the air conditioner 90 will be described. Fig. 3 is a perspective view of the air conditioner 90. Fig. 4 is a block diagram for explaining the internal hardware configuration of the air conditioner 90. Fig. 5 is a block diagram for explaining the software configuration of the air conditioner 90.

[0037] The air conditioner 90 is a ceiling-mounted indoor unit, and its exterior comprises a casing 91, a ceiling panel 92, four fixing portions 93, and eight connector receiving portions 94. Inside the space surrounded by the casing 91 and the ceiling panel 92, it also comprises a control portion 95, an air conditioning portion 96, a power supply portion 97, a converter 98, and a lighting connection portion 99.

[0038] The casing 91 is a box-shaped body with an open bottom surface, and forms the side and top surfaces of the air conditioner 90. The top surface has a square or rectangular shape, with four side surfaces that correspond to the sides of the top surface, intersecting perpendicularly and extending downward. The edges of the top surface where the edges intersect are chamfered, and the chamfered areas are also straight. Therefore, flat surfaces are provided on the side surfaces corresponding to the chamfered areas. Here, the four side surfaces corresponding to the rectangular shape are called main side surfaces, and the side surfaces corresponding to the chamfered areas at the ends are called end side surfaces.

[0039] A fixing portion 93 is provided on each of the four end side surfaces of the casing 91. The air conditioner 90 is fixed to the hanging material 30 using the fixing portion 93. Two connector receiving portions 94 are provided side by side in the horizontal direction on each of the four main side surfaces of the casing 91. A connector of the wiring connected to the lighting fixture 10 can be connected to the connector receiving portion 94. The fixing portion 93 and the connector receiving portion 94 may be provided on the same side surface. Specifically, both may be provided on the end side surfaces. Alternatively, both may be provided on the main side surfaces. Furthermore, they may be provided on both the main side surfaces and the end side surfaces.

[0040] The ceiling panel 92 forms the ceiling surface on its underside and is connected to the casing 91 on its top side. It is attached to the casing 91 so as to cover the opening of the casing 91. The ceiling panel 92 is also provided with an outlet for blowing out cool air and warm air generated by the air conditioning unit 96, and an inlet for drawing in air from inside the room. The top and bottom surfaces of the ceiling panel 92 have a square or rectangular shape, and each of the four sides is parallel to the corresponding main side surfaces of the casing 91. Therefore, the ceiling panel 92 is attached so that each side of the top or bottom surface is aligned with the main side surfaces of the casing 91.

[0041] The control unit 95 has a ROM, a RAM, a CPU, etc. The ROM is a memory that stores various programs and data used by the programs. The RAM is a memory that is used as a storage area for loading programs and a work area for the loaded programs. The CPU is a processor that realizes various functions by processing the programs loaded into the RAM.

[0042] The air conditioning unit 96 has an indoor heat exchanger, an indoor fan, a drain pan, etc. The indoor heat exchanger is a fin-and-tube type heat exchanger that functions as a refrigerant evaporator to cool the indoor air during cooling operation, and as a refrigerant condenser to heat the indoor air during heating operation.

[0043] The indoor fan is a crossflow fan and includes a fan and a fan motor for rotating the fan. The indoor fan draws in indoor air and blows it out into the room. The air drawn in by the indoor fan through the intake port is conditioned by heat exchange in the indoor heat exchanger, and the conditioned air is blown out into the room through the outlet port. The indoor fan can adjust the air volume supplied to the indoor heat exchanger within a specified air volume range. The drain pan collects drainage produced when moisture in the air condenses during heat exchange in the indoor heat exchanger.

[0044] The power supply unit 97 supplies a power supply voltage for operating the air conditioning unit 96. The power supply voltage is also supplied to the lighting fixture 10 via a lighting connection unit 99. When supplying the power supply voltage to the lighting fixture 10, the converter 98 converts the power supply voltage supplied from the power supply unit 97 into a power supply voltage that conforms to the specifications of the lighting fixture 10. Therefore, when supplying the power supply voltage to the lighting fixture 10, the power supply unit 97 supplies the power supply voltage from the lighting connection unit 99 to the lighting fixture 10 via the converter 98.

[0045] The ceiling-mounted air conditioner 90 is connected to, for example, a 200V AC power source to receive a power supply voltage in order to control the air conditioning of a large room space. On the other hand, the lighting fixture 10 operates on a 100V DC power supply voltage. In such a case, the converter 98 converts the 200V AC power supply voltage into a 100V DC power supply voltage. The converter 98 may not be built into the air conditioner 90, but may be connected to the air conditioner 90 by wiring. When supplying a power supply voltage to the lighting fixture 10, the power supply unit 97 supplies the power supply voltage converted by the converter.

[0046] The lighting connection portion 99 has eight connection portions, numbered from the first connection portion to the eighth connection portion. The eight connection portions correspond one-to-one to the eight connector receptacles 94. These provide electrical connection for supplying power supply voltage to the lighting fixtures 10 connected to the wiring inserted into the connector receptacles 94.

[0047] The control unit 95 has the functions of an operation reception unit 951, an air conditioning operation control unit 952, and a lighting power control unit 953. Each of these functional units is realized by processing that a program causes the CPU to execute. The operation reception unit 951 receives user operations on the air conditioner 90. It also receives user operations on the lighting fixture 10. User operations are performed using an operation unit installed on the wall 3 of the room or a portable remote operation unit, and the operations include, for example, turning on / off the air conditioning function and lighting.

[0048] The air conditioning operation control unit 952 controls the operation of the air conditioning unit 96 and the power supply unit 97 to control the air conditioning function. For example, it causes the power supply unit 97 to supply power voltage to drive the motor of the air conditioning unit 96, causing the indoor fan to function. The operation of the air conditioning unit 96 is adjusted based on the operation instructions received by the operation receiving unit 951. For example, it controls based on instructions such as whether to perform cooling or heating operation, the set temperature, and the airflow rate.

[0049] The lighting power supply control unit 953 controls the supply of power supply voltage to the lighting fixture 10 connected via the connector receptacle 94. The power supply voltage from the power supply unit 97 is converted by the converter 98, and a power supply voltage suitable for the lighting fixture 10 is supplied from the connection unit connected to the lighting fixture 10.

[0050] Next, the process up to the installation of the air conditioning device 90 in the construction of the building 1 according to the first embodiment will be described. Note that differences from the process up to the construction of a building already described using FIG. 1 will be described in detail, and explanations of overlapping points will be simplified or omitted.

[0051] The processes from step S2 to step S4 are generally the same as those already explained. Next, in the interior construction work of step S5, ceiling construction is carried out to install the ceiling. Furthermore, before the ceiling is installed, the wiring to be laid above the ceiling is routed to a position higher than the ceiling. Figure 6 shows an example of the above-ceiling space after ceiling construction has been completed. Figure 6 also shows an example of the above-ceiling space in area A of the living room in Figure 2.

[0052] As shown in FIG. 6, the attic space has a top and side formed by a concrete frame 80, and an underside formed by a ceiling 4 on which ceiling materials 40 are arranged. Furthermore, each ceiling material 40 forming the ceiling 4 is fixed and supported by hanging materials 20 connected to a ceiling insert in the frame 80. Furthermore, four hanging materials 30 are provided per air conditioning unit 90 to fix the air conditioning unit 90. Note that the number of hanging materials 30 per air conditioning unit 90 does not need to be limited to four. At the time of FIG. 6, the air conditioning unit 90 has not yet been installed, and the hanging materials 30 are not supporting the air conditioning unit 90.

[0053] Wiring 50 is provided in the attic space, running through piping. This wiring is provided based on the design drawings and corresponds to the number of air conditioners 90 to be installed in the attic. Wiring 50 is provided to receive power supply voltage from an external power source through piping. The power supply voltage supplied to air conditioners 90 is higher than the voltage supplied to lighting fixtures 10, and in this case, 200V AC power supply voltage can be supplied by connecting to wiring 50. Note that the wiring is not limited to that for air conditioners 90, and a sufficient number of wires are provided and installed in ceiling 4 to supply power to other electrically connected devices.

[0054] The ceiling material 40 has openings for installing ceiling-mounted fixtures such as an air conditioner 90 and lighting fixtures 10. The square openings are for the air conditioner 90, and the circular openings are for the lighting fixtures 10. In the example of FIG. 9 , there are a total of nine ceiling materials 40 in a 3×3 arrangement, and an opening for installing the air conditioner 90 is provided in the central ceiling material 40. Furthermore, openings for installing the lighting fixtures 10 are provided in each of the three ceiling materials 40 on either side of this ceiling material. In areas B to D, although the positional relationship with the frame 80 differs, hanging materials 20, hanging materials 30, ceiling materials 40, and wiring 50 are provided in the same manner.

[0055] After the ceiling 4 is installed in this manner, the air conditioning unit 90 is installed in the facility construction work of step S6. Figures 7 and 8 are diagrams for explaining the installation method of the air conditioning unit 90. Figure 7 shows the connection relationship between the hanging material 30, ceiling material 40, and air conditioning unit 90 viewed from above the ceiling surface (living space side). Figure 8 also shows the structure of the air conditioning unit 90 installed on the ceiling as viewed from above the ceiling.

[0056] Once ceiling 4 is installed in a building, the living space, which is the space that forms the living room shown in Figure 2, and the attic space, which is the space that forms the attic space shown in Figure 6, are treated as separate spaces separated by the ceiling surface. The ceiling surface is the plane on which the ceiling material is installed. In other words, the space above (above) ceiling 4, separated by the ceiling surface, is the attic space, and the space below (below) is the living space. For example, in a building with two or more floors, the attic space of the first floor is located below the living space on the second floor, with the building structure in between.

[0057] As shown in FIG. 7 , before the air conditioner 90 is fixed to the hanging material 30 and the opening in the ceiling material 40 is closed, wiring 60 with a connector is prepared to run through the attic space. On the other hand, wiring 50 does not have a connector. Wiring 60 may be prepared after the air conditioner 90 is fixed to the hanging material 30, as long as it is before the opening for the air conditioner 90 is closed. This wiring 60 is a wiring cable for connection to the lighting fixtures 10. Furthermore, the air conditioner 90 in area A is connected to the lighting fixtures 10 installed in area A. Therefore, wiring 60 is prepared for the number of lighting fixtures 10 connected to the air conditioner 90 in area A, and based on the example of FIG. 6 , six wirings 60 are prepared. Note that, to conveniently distinguish between wiring 50 and wiring 60, wiring 50 may be referred to as the first wiring and wiring 60 as the second wiring.

[0058] To supply power to the air conditioner 90, the wiring 50 must be connected. In Japan, this work must be performed by a person qualified as an electrician. Furthermore, the connectors of the six wiring 60 are inserted into six of the eight connector receptacles 94 of the air conditioner 90 and connected to the lighting connection 99. This work can be performed by a person who is not qualified as an electrician. The connector can be inserted into any connector receptacle 94, but it is preferable to insert it into a connector receptacle 94 located close to the lighting fixture 10. This is to minimize the risk of the wiring becoming tangled or crossed.

[0059] The reason why the air conditioner 90 has multiple connector receptacles 94 on its four main side faces is to allow for flexible response to the relative positioning of the air conditioner 90 and the lighting fixtures 10, i.e., the layout of the ceiling 4 in a room. The number of connector receptacles 94 and lighting connection parts 99 does not need to be limited to eight. However, considering the relationship between the air-conditioned area covered by one ceiling-embedded air conditioner 90 and the lighting area covered by one lighting fixture 10, an air conditioner provided with four or more connector receptacles 94 is preferable.

[0060] Furthermore, instead of providing the connector receiving portions 94 evenly on all four main side surfaces, they may be provided on two opposing main side surfaces. From the perspective of flexible layout, it is preferable to provide them on multiple main side surfaces, but even in an air conditioner with four or more connector receiving portions on one main side surface, wiring connections are not impossible and it is feasible. The number of connector receiving portions provided in one air conditioner is preferably 16 or less, because if there are too many, many will go unused, which is inefficient. However, this does not mean that air conditioners with 17 or more connector receiving portions are not permitted.

[0061] As shown in Fig. 8, an air conditioner 90 connected to six wires 60 is fixed to a hanging material 30 by fixing parts 93 and installed on the ceiling. Each of the six wires 60 is passed through an opening in a ceiling material 40 corresponding to each of the lighting fixtures 10 installed around the air conditioner 90. The lighting fixtures 10 and the wires 60 are connected beyond this opening and installed on the ceiling material 40. Note that the air conditioner 90 is connected to the wires 50 before being installed on the ceiling, but the wires 50 are omitted from Fig. 8.

[0062] Next, a lightweight large-sized lighting fixture will be described as an example of the lighting fixture 10 to be installed on the ceiling material 40. Fig. 9 is a perspective view of the lighting fixture 10 as seen from the installation surface side where it is installed on the ceiling. Fig. 10 is a schematic diagram for explaining the light-emitting surface of the lighting fixture 10. Fig. 11 is a perspective view showing a light source element 16 used in the lighting fixture 10. The lighting fixture 10 described based on Figs. 10 and 11 is a lighting fixture with a square light-emitting surface, measuring 450 mm in length and 450 mm in width, with a height from the ceiling installation surface to the light-emitting surface of 20 mm.

[0063] The light-emitting surface may be a square lighting fixture measuring 600 mm in height and 600 mm in width. Alternatively, the light-emitting surface may be a rectangular lighting fixture measuring 150 mm in height and 600 mm in width. It is preferable that the height and width are configured in 150 mm increments, as this conforms to the specifications of the ceiling material. In other words, the height and width are multiples of 150 mm so that they can be treated in the same way as ceiling materials. In other words, as long as the size conforms to the specifications of the ceiling material, it does not have to be 150 mm. For example, in a place where one foot is used as a unit, the height and width can be configured in multiples of one foot.

[0064] The lighting fixture may be a rectangle measuring 75 mm in height and 600 mm in width. The light-emitting surface may also be any other polygon, circle, or ellipse, and the shape is not limited. In this application, shapes with chamfered corners are also referred to as squares or rectangles.

[0065] The lighting fixture 10 has a base plate 11, a cover 12, a buffer section 13, a DC harness 14, a substrate 15, and a light source element 16. The base plate 11 functions as a reinforcing plate or a heat sink for the lighting fixture 10. For example, the base plate 11 is a metal plate formed in a rectangular shape. For example, the metal plate can be formed from aluminum.

[0066] In this specification, the term "light source" refers to a component that emits light, and the light source may be a light-emitting element such as an LED, or may be a combination of a light-emitting element and a wavelength conversion component. The term "wavelength conversion component" refers to a component that converts part or all of the light emitted by the light-emitting element into light of a different wavelength, such as a phosphor component.

[0067] The cover 12 is provided to cover the light source elements 16 arranged on the substrate 15. The cover 12 is translucent to the light emitted by the light source elements 16. The cover 12 is formed in a milky white color with light diffusing properties, for example, by dispersing titanium oxide or the like in a resin material. For example, an acrylic resin, such as polymethyl methacrylate resin, can be used as the resin material.

[0068] The buffer section 13 is provided on the outer periphery of the ceiling installation surface of the base plate 11. The buffer section 13 prevents the ceiling installation surface of the base plate 11 from coming into direct contact with the ceiling 4 (or ceiling material 40), thereby cushioning impacts. Furthermore, the buffer section 13 is not provided on a portion of the outer periphery of the base plate 11, and the thickness of the buffer section 13 provides a removal arm insertion port G.

[0069] The DC harness 14 is fitted into a socket 70, which will be described later. The socket 70 is attached to the ceiling material 40, and the DC harness 14 is attached to the ceiling 4 via the socket 70.

[0070] The substrate 15 is an insulating substrate made of, for example, resin or ceramic, and has a light source mounting surface on which multiple light source elements 16 are arranged. The light source mounting surface of the substrate 15 is provided with a conductive pattern for supplying power to the light source elements 16. The material of the conductive pattern can be selected appropriately depending on the main material of the substrate 15. 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 conductive wiring may be made of a material containing a high-melting point metal such as tungsten and / or molybdenum. Furthermore, other metal materials such as nickel, gold, and / or silver may be provided as coating materials on the conductive pattern by plating, sputtering, vapor deposition, or the like. Furthermore, in the case of a substrate made of a resin material, the conductive pattern preferably is easy to process. For example, in the case of a substrate made of injection-molded resin, the conductive pattern preferably is easy to process by processes such as punching, etching, or bending, and has relatively high mechanical strength. Specific examples of materials for the conductive pattern include metals such as copper, aluminum, gold, silver, tungsten, rhodium, iron, nickel, and molybdenum, as well as iron-nickel alloys, phosphor bronze, and iron-containing copper.

[0071] 6 shows a view in which a portion covered by cover 12 has been removed so that the internal structure of cover 12 can be seen. Therefore, in reality, substrate 15 and light source element 16 in illumination fixture 10 are covered by cover 12. The surface of substrate 15 opposite the light source arrangement surface is in contact with base plate 11. Substrate 15 has a plurality of screw holes S, and is fixed to base plate 11 with screws via the screw holes S.

[0072] The light source elements 16 are evenly arranged on the substrate 15. On a light source arrangement surface measuring 450 mm square, the light source elements 16 are arranged at pitch intervals of 15 mm to 20 mm. As shown in FIG. 7 , the light source elements 16 include light emitting elements 17, a wavelength conversion member 18, and a sealing member 19. The light emitting elements 17 are mounted on the light source arrangement surface of the substrate 15, and electrodes of the light emitting elements 17 are electrically connected to a conductive pattern formed on the substrate 15. The wavelength conversion member 18 covers the light emitting elements 17.

[0073] The sealing member 19 can be made of a material that is electrically insulating, transparent to light emitted from a light source (e.g., transmittance of 70% or more), and fluid before solidification (e.g., before complete curing). For example, it may contain a resin raw material, such as silicone resin, epoxy resin, phenolic resin, polycarbonate resin, acrylic resin, TPX resin, polynorbornene resin, or modified or hybrid resins thereof. Silicone resin is particularly preferred because of its excellent heat resistance and / or light resistance (as used herein, "silicone resin" refers to "silicone-based resin," which encompasses modified resins or resins having at least a silicone skeleton). Such sealing raw materials may additionally contain fillers and / or phosphors, etc., as needed.

[0074] The sealing member 19 covers the wavelength conversion member 18. The portion of the sealing member 19 that covers the vicinity of the center of the top surface of the light emitting element 17 is recessed. In addition, multiple protrusions are provided in the peripheral portion surrounding this recessed portion. The protrusions are provided approximately evenly around the periphery of the recessed portion, and the recessed portion is contained within the area surrounded by the straight lines connecting adjacent protrusions. In this way, the sealing member 19 has a flat shape overall, and furthermore, the sealing member 19 having the recessed portion and multiple protrusions provides the light source element 16 with a batwing-shaped light distribution characteristic.

[0075] In order to obtain suitable batwing-shaped light distribution characteristics, it is preferable that the size of the protrusion is not too large. For example, regarding the sealing member 19, if the height of the protrusion itself is "h" and the height of the bulge (the height of the sealing member excluding the protrusion) is "H", it is preferably 0 < h ≦ H / 8, more preferably 0 < h ≦ H / 10, and even more preferably 0 < h ≦ H / 12.

[0076] In addition, the sealing member 19 has at least a maximum thickness dimension smaller than the maximum width dimension. For example, the maximum width is at least twice the maximum thickness. The maximum thickness is preferably the height from the substrate 15 to the top of the protrusion of the sealing member 19. Such a flat-shaped sealing member provides batwing light emission from a lower height. Also, it is possible to suppress problems such as the light source element 16 being detached from the substrate due to accidental external force.

[0077] As an example of the lighting fixture 10 with a length of 450 mm, a width of 450 mm, and a height from the ceiling installation surface to the light-emitting surface of 20 mm, in which a total of 576 light source elements 16 arranged in a 24×24 grid, the total luminous flux is 4500 lm, the color temperature is 5000 K, and the weight is 1.94 kg. That is, the lighting fixture 10 in one embodiment satisfies one or more of the following conditions: the total luminous flux is 4000 lm or more, the area of the light-emitting surface, which is the surface closest to the floor, is 202500 mm 2 or more, there are 500 or more light source elements arranged, or the weight is less than 2.0 kg, and it is an example of a lightweight large-sized lighting fixture.

[0078] As another example of the lighting fixture 10, which is different in that the light-emitting surface has a length of 150 mm and a width of 600 mm, in which a total of 256 light source elements 16 arranged in an 8×32 grid, the total luminous flux is 3450 lm, the color temperature is 2700 K, and the weight is 1.09 kg. That is, the lighting fixture 10 in another embodiment satisfies one or more of the following conditions: the total luminous flux is 3000 lm or more, the area of the light-emitting surface, which is the surface closest to the floor, is 90000 mm 2 or more, there are 200 or more light source elements arranged, or the weight is less than 1.5 kg, and it is an example of a lightweight large-sized lighting fixture.

[0079] Next, the installation process of the lighting fixture 10 in the construction of the building 1 according to the present application will be described. FIG. 12 shows the connection relationship between the ceiling material 40, the wiring 60, the socket 70, and the lighting fixture 10 as viewed from the ceiling surface. The wiring 60 is provided with a connector for connecting to the lighting fixture 10 at the other end opposite to the end provided with a connector for connecting to the air conditioning unit 90. Note that this connector may be the same type as the connector connected to the air conditioning unit 90, or may be a different type. Note that for convenience of distinction, the connector connected to the air conditioning unit 90 may be referred to as the first connector, and the connector connected to the lighting fixture 10 may be referred to as the second connector.

[0080] In ceiling construction, the work of running the wiring above the ceiling is performed by a wiring worker who is qualified as an electrician. In addition, the work of connecting the air conditioning unit 90 to the wiring 50 is also performed by an air conditioning installation worker who is qualified as an electrician.

[0081] On the other hand, the wiring 60 with the first and second connectors can be prepared in advance as a wiring cable having a length of several meters or more. Furthermore, for example, a LAN cable capable of both power supply and communication can be used as the wiring cable. By using the wiring 60 equipped with electric shock-prevention connectors such as the first and second connectors, the work of connecting the lighting fixture 10 to the wiring 60 can be performed by a person who is not a licensed electrician. In other words, once the work of connecting the wiring 50 and the air conditioning unit 90 has been completed, the work of installing the lighting fixture 10, including the work of connecting the wiring to supply power to the lighting fixture 10, can be performed by a person who is not a licensed electrician.

[0082] As shown in FIG. 12, the opening provided for installing the lighting fixture 10 is smaller than the ceiling material 40. It is also sufficiently small compared to the light-emitting surface of the lighting fixture 10. In this specification, "sufficiently small" means that the opening is 1 / 3 or less of the area of ​​the light-emitting surface. "Very small" means that the opening is 1 / 5 or less of the area of ​​the light-emitting surface. "Extremely small" means that the opening is 1 / 10 or less of the area of ​​the light-emitting surface.

[0083] The opening for installing the lighting fixture 10 is formed, for example, in a circular shape with a diameter of 10 cm to 15 cm. The shape of the opening does not have to be circular, and may be a polygon with a maximum diameter of 15 cm or less. The shape of the opening may be determined based on the size and shape of the socket 70, etc. As will be described later, it is preferable that the opening be large enough for a worker's arm to fit through so that the wiring 50 can be reached from the living room side to install the lighting fixture 10.

[0084] As a specific example of the opening, a circular opening with a diameter of 15 cm is provided to install a lighting fixture 10 that is 450 mm long, 450 mm wide, and 20 mm high from the ceiling mounting surface to the light-emitting surface. Therefore, the lighting fixture 10 can be installed through an extremely small opening. As another example, a circular opening with a diameter of 12.5 cm is provided to install a lighting fixture 10 that is 150 mm long, 600 mm wide, and 20 mm high from the ceiling mounting surface to the light-emitting surface. Therefore, the lighting fixture 10 can be installed through an extremely small opening.

[0085] It should be noted that the ceiling material 40 does not need to have openings pre-formed. It is common practice to prepare the ceiling material 40 without openings, and then have workers drill holes in the ceiling material 40 at the site where the interior construction work is being carried out to create openings. The work of creating openings in the ceiling material 40 without openings can be carried out as needed. The shape of the openings that should be prepared may vary depending on the type of ceiling-mounted fixture to be installed. Therefore, the openings can be created when the ceiling material 40 is fixed to the ceiling with the hanging material 20 and attached to the ceiling, or they can be created after the ceiling is formed.

[0086] A worker present in the living space prepares the lighting fixture 10 and the socket 70 in the living space, and inserts the DC harness 14 of the lighting fixture 10 into the socket 70. The lighting fixture 10 and the socket 70 are then fitted and fixed together by the fitting portion of the socket 70 and the fitting portion of the lighting fixture 10. Then, by inserting the second connector of the wiring 60 into the socket 70, the lighting fixture 10 is electrically connected, and can receive power supply voltage from an external power source via the air conditioning device 90.

[0087] The socket 70 has a connector receptacle as a connection part for connecting to the second connector of the wiring 60. A worker in the living space can simply pull the wiring 60, which runs through the attic space, into the living space and perform the connection work. Note that in cases where the lighting fixture 10 has a dimming function for adjusting the intensity and color tone of the light emitted, the socket 70 may have a separate connector receptacle as a connection part for connecting to a dimming driver device that controls the dimming. Note that, for convenience of distinction, the connector receptacle for power supply is sometimes referred to as the power connector receptacle, and the connector receptacle for dimming is sometimes referred to as the dimming connector receptacle.

[0088] Furthermore, the socket 70 has a fastener 71, and a worker present in the living space uses this fastener 71 to install the socket 70 in the ceiling material 40. The fastener 71 has spring properties (elasticity), and is passed through an opening in the ceiling material 40 from the ceiling surface side (living space side). After passing through, the fastener 71 is applied to the underside of the ceiling material 40, and therefore the load is applied to the ceiling material 40. When the lighting fixture 10 is attached to the ceiling 4, the load of one lighting fixture 10 and one socket 70 is applied to one ceiling material 40. Note that the fastener 71 is not limited to a structure having spring properties, and may be of any structure that applies a load to the ceiling material 40.

[0089] It is not important whether the operation of connecting the connector of the wiring 60 to the socket 70 or the operation of connecting the socket 70 to the lighting fixture 10 is performed first. The operation of attaching the socket 70 to the ceiling material 40 may be performed before or after connecting the lighting fixture 10 to the socket 70. The socket 70 may be formed integrally with the lighting fixture 10 in advance. In other words, the lighting fixture 10 with the socket may be connected to the second connector of the wiring 60.

[0090] As an example, socket 70 is attached to a circular opening with a diameter of 150 mm, and the penetration area that passes through the opening, excluding fastener 71, is a circle with a diameter of 148 mm, and the ceiling surface side that contacts the ceiling surface is a circle with a diameter of 160 mm. In addition, when combined with the weight of lighting fixture 10, which is 450 mm long, 450 mm wide, and has a height of 20 mm from the ceiling installation surface to the light-emitting surface, the load applied to ceiling material 40 is 2.00 kg.

[0091] In another example, socket 70 is attached to a circular opening with a diameter of 125 mm, and the penetration area that passes through the opening, excluding fastener 71, is a circle with a diameter of 123 mm, and the ceiling surface side that contacts the ceiling surface is a circle with a diameter of 130 mm. In addition, the weight of lighting fixture 10, which is 150 mm long, 600 mm wide, and has a height of 20 mm from the ceiling installation surface to the light-emitting surface, combined with the weight of lighting fixture 10, is 1.10 kg.

[0092] As a guideline, a ceiling-mounted fixture with a load of less than 3.0 kg applied to the ceiling material 40 can be installed on the ceiling without requiring fixing with the hanging material 20. In this regard, in all of the above-mentioned embodiments, the socket 70 and the lighting fixture 10 are installed on the ceiling material 40, and the total load thereof satisfies the requirement of less than 3.0 kg.

[0093] In this way, the installation work of the lighting fixture 10 does not require fixing with the hanging material 20, so it is sufficient to provide an opening large enough to pull the wiring 60 in the ceiling space into the living space. In other words, to install the lighting fixture 10 on the ceiling 4, all that is required is an opening large enough for an arm to fit through.

[0094] Furthermore, the work of connecting the lighting fixture 10 and the wiring 60 can be performed by someone who is not a licensed electrician. In other words, this connection work is performed in a manner that is permitted even for someone who is not a licensed electrician. This means that during the construction of the building 1, the installation work of the lighting fixture 10 can be efficiently carried out in parallel with the installation work of the air conditioning unit 90. In other words, a person who is a licensed electrician can perform the wiring work for the air conditioning unit 90, and an unlicensed person can perform the installation work of the surrounding lighting fixtures 10, and the installation work of the lighting fixture 10 and the air conditioning unit 90 can be performed together. Note that the installation process of the lighting fixture 10 may be performed before the installation process of the air conditioning unit 90.

[0095] In this way, in a room where lighting fixtures 10 and air conditioners 90 are installed, an efficient system can be constructed in which the air conditioners 90 control the power supply to the lighting fixtures 10 located nearby, as shown in Fig. 2. In the example of Fig. 2, in each of areas A to D, the air conditioners 90 installed in that area control the power supply to the lighting fixtures 10 installed in that area. This allows the air conditioners 90 to also control the lighting within their own air-conditioning range.

[0096] It is preferable that the plurality of lighting fixtures 10 installed on the ceiling 4 are connected to the air conditioner 90 located closest to the lighting fixtures 10 via wiring 60. It is also preferable that the distance between an air conditioner 90 and the lighting fixture 10 closest to that air conditioner 90 is within 1.0 m. The connection relationship between the lighting fixtures 10 and the air conditioner 90 in the living room in Figure 2 satisfies this requirement.

[0097] Furthermore, the air conditioning unit 90 does not need to be connected to all of the lighting fixtures 10 at all of the connector receptacles 94; it can be connected to an appropriate number of lighting fixtures 10 according to the layout of the room. Changing the lighting fixture 10 to be connected can be done simply by disconnecting the connected wiring 60 and inserting the wiring 60 of the new lighting fixture 10 into the connector receptacle 94, making it easy to change the lighting fixtures 10 that are the targets of control from the air conditioning unit 90. In particular, by using lightweight, large lighting fixtures as the lighting fixtures 10, even if it becomes necessary to change the location or number of lighting fixtures 10 after the framework construction is completed, there is no need to prepare new hanging materials, and changes can be made flexibly. Furthermore, the air conditioning unit 90 can flexibly accommodate changes to the number of lighting fixtures 10 that control the power supply.

[0098] Although the example in which each lighting fixture 10 is connected to each connector receptacle 94 of the air conditioner 90 has been described, the lighting fixture 10 connected to the wiring 60 connected to the connector receptacle 94 may be connected to other lighting fixtures 10 by a separate wiring, and power may be supplied in a relay manner. In this case, power can be supplied to multiple lighting fixtures 10 with at least one connector receptacle 94. Furthermore, the lighting fixtures 10 can be connected to each other by wiring 60 having a first connector at one end for connecting to the lighting fixture 10 to receive power from the air conditioner 90 and a second connector at the other end. In either case, the same number of wiring 60 as the number of lighting fixtures 10 receiving power from the air conditioner 90 is prepared. The air conditioner 90 also controls the power supply to multiple lighting fixtures 10 installed nearby. It is preferable that one air conditioner 90 requests power from four or more lighting fixtures 10 in its vicinity.

[0099] FIG. 13 shows an example of an equipment control system 1000 that manages the output of lighting fixtures 10 and air conditioners 90 in the room shown in FIG. 2. The equipment control system 1000 includes multiple air conditioners 90 installed in areas A to D, multiple lighting fixtures 10 connected to each air conditioner 90, an operation unit 100 for operating each air conditioner, and a remote server 500 that manages the air conditioning and lighting of the entire building 1 or the entire room. In this equipment control system 1000, the air conditioners 90 are communicatively connected to the operation unit 100 and the remote server 500. The air conditioners 90 can also control the operation of the lighting fixtures 10 connected to them via a lighting connection unit 99. An operation reception unit 951 of the air conditioners 90 receives instructions from the operation unit 100 or the remote server 500, and the air conditioners 90 controls the output of the lighting fixtures 10 connected to them. Note that the remote server 500 is not essential to the equipment control system 1000.

[0100] With this device control system 1000, for example, a user can use the operation unit 100 to simultaneously operate the air conditioner 90 and the lighting fixture 10. When operating the air conditioner 90 in a certain area of ​​a room, the user can issue a command to perform synchronized control, such as turning on a lighting fixture 10 nearby the air conditioner 90, simply by pressing an operation button provided on the operation unit 100. The operation button here may be implemented as a hardware key or as a software key on a screen. Because the synchronization target is a nearby lighting fixture 10, there is no need to turn on lighting fixtures 10 in distant positions (in other distant areas), which contributes to energy conservation.

[0101] Conventionally, an operating unit for operating the air conditioner 10 and a switch for turning the lighting fixture 10 on and off have been provided separately on the wall 3 of the room, making it impossible to operate them together. However, with this device control system 1000, it is possible to control multiple lighting fixtures 10 and one air conditioner 90 in each area in a coordinated manner, for each area that divides the room, and to provide the user with an operating screen that brings together the operating unit and the switch.

[0102] In the example of FIG. 13, one operating unit 100 controls one air conditioner 90 and multiple lighting fixtures 10 connected to that air conditioner 90, but this is not limiting, and one operating unit 100 may control multiple air conditioners 90 installed in one area and multiple lighting fixtures 10 connected to those multiple air conditioners 90. In other words, an operating unit 100 may be provided for each area rather than for each air conditioner 90. Also, all areas may be configured with one operating unit 100 that can operate each area individually. In the large living space of an office building, it is not uncommon for multiple air conditioners installed in the area to be operated by one operating unit.

[0103] FIG. 14 shows an example of an operation screen for operating multiple lighting fixtures 10 and multiple air conditioners 90 installed in a room, area by area, using a single operation unit 100. As shown, an area name for each area, such as "Area A" or "Area B," is displayed. Each area is provided with a collective operation button 101 for collectively turning on / off the lighting and air conditioning, a lighting operation button 102 for collectively turning on / off only the lighting, and an air conditioning operation button 103 for collectively turning on / off only the air conditioning. These operation buttons display symbols, such as letters and pictures, that allow the user to intuitively recognize whether to operate the lighting and air conditioning collectively or individually. The operation unit 100 also includes a temperature adjustment button 104 for adjusting the set temperature of the air conditioning, and, if the lighting has a dimming function, a brightness adjustment button 105 for adjusting the lighting intensity. Displaying such an operation screen on the operation unit 100 eliminates the need to separately install a lighting switch and an air conditioning controller on the wall 3, improving user operability.

[0104] Second Embodiment Next, an air conditioner 290 in a building according to the second embodiment will be described. Fig. 15 is a perspective view of the air conditioner 290. Fig. 16 is a block diagram illustrating the hardware configuration of the air conditioner 290.

[0105] The air conditioning device 290 of the second embodiment is similar to the first embodiment in that it includes a first connector receptacle 94 for supplying power voltage to the lighting fixture 10, but differs from the first embodiment in that it includes a second connector receptacle 294 for controlling the dimming of the lighting fixture 10. Note that a single connector receptacle may be connected to wiring for power supply and communication, enabling both power supply and dimming control. In other words, the first connector receptacle 94 and the second connector receptacle 294 may be integrated into a single connector receptacle. Alternatively, a connector receptacle for dimming control may be provided, but a connector receptacle for power supply may not be provided. In this case, the lighting fixture 10 is connected via wiring so that it receives power from a different route than the air conditioning device 290.

[0106] Also, with the provision of the second connector receptacle 294, the lighting connection section 299 is provided with first to eighth lighting connection sections for supplying power supply voltage to each of the lighting fixtures 10, as well as first to eighth dimming connection sections for controlling the dimming of each of the lighting fixtures 10. The control section 295 is also equipped with a driver program for controlling the dimming of the lighting fixtures 10, and a dimming control section 954 that executes dimming control for the lighting fixtures 10 functions based on this driver program.

[0107] As described above, in the second embodiment, the air conditioner 290 can not only supply power voltage to the lighting fixture 10 connected to the connector receptacle, but also perform dimming control. For example, the color temperature of the lighting can be controlled to change depending on whether the air conditioner 90 is operating in cooling mode or heating mode. For example, during cooling mode, the color temperature of the lighting can be adjusted to a bluish white color, giving the user a visual sensation of coolness, and during heating mode, the color temperature of the lighting can be adjusted to an orangey white color, giving the user a visual sensation of warmth.

[0108] The above describes the building, the method for constructing the building, and the method for installing the lighting fixture in the constructed building according to the present invention based on each embodiment, but the technical concept of the present invention is not limited to the specific embodiments described above. In the embodiments, an example in which the lighting fixture according to the present invention is installed in a living room has been described, but the installation location is not limited to a living room and may be, for example, a front entrance or a hall. The living space is not limited to a living room and may refer to a space located on the opposite side of the ceiling from the attic.

[0109] Furthermore, the present invention can be applied even if it is not essential to have all of the components disclosed in each embodiment. A person skilled in the art or in the technical field to which the invention pertains can apply the present invention even if some of the components disclosed in the embodiments are not recited in the claims, as long as it is within the scope of design freedom, and the present specification discloses the invention on the premise that this includes such cases. [Industrial Applicability]
