Hereinafter, embodiments will be described with reference to the drawings. In each drawing, the same elements are designated by the same reference numerals.

FIG. 1 is a side view of the lamp body 10 and the fitting adapter 40 of the first embodiment.
FIG. 2 is a front view of the lamp main body 10.
FIG. 3 is a rear view of the lamp body 10 and the fitting adapter 40.

The lamp body 10 has a base plate 11 and a translucent cover 30. As shown in FIG. 2, the cover 30 has a rectangular main light emitting surface (or main surface portion) 31.

A fitting adapter 40 is provided on the back surface of the base plate 11. The fitting adapter 40 is fixed to the back surface of the base plate 11. A DC (direct current) input connector 45 is connected to the fitting adapter 40.

As shown in FIG. 3, a leaf spring 15 is provided on the back surface of the base plate 11. For example, two leaf springs 15 having a rectangular shape or a strip shape are provided on the back surface of the base plate 11. The leaf spring 15 is, for example, a glass-containing resin member. Each leaf spring 15 is fixed to the back surface of the base plate 11 with two screws 16. The two screws 16 are separated in the longitudinal direction with the center of the leaf spring 15 in the longitudinal direction interposed therebetween.

The two leaf springs 15 extend parallel to each other along one side of the rectangular base plate 11. The two leaf springs 15 are separated from each other in a direction orthogonal to the extending direction, and are symmetrically arranged with respect to the fitting adapter 40 provided at the center of the base plate 11. Further, on the back surface of the base plate 11, a cushion material 18 is provided along the outer edge portion.

The lamp body 10 further includes a light source module 20.
FIG. 4 is a schematic cross-sectional view of the light source module 20 and the cover 30.
FIG. 5 is a front view of the light source module 20.
FIG. 27 is a front view of another example of the light source module 20.

The light source module 20 is attached to one surface of the base plate 11, and the cover 30 is attached to the base plate 11 so as to cover the light source module 20. The main surface portion 31 of the cover 30 faces the light source module 20 with a space 70 in between. Further, the side surface portion of the cover 30 covers the side surface of the space 70. The base plate 11 is, for example, a metal plate, and functions as a reinforcing plate and a heat radiating plate of the light source module 20.

The light source module 20 has a substrate 21 and a plurality of light sources 22. The substrate 21 has a light source arranging surface 21a and a back surface 21b on the opposite side of the light source arranging surface 21a. A plurality of light sources 22 are periodically arranged on the light source arrangement surface 21a of the substrate 21. In the example shown in FIGS. 5 and 27, the plurality of light sources 22 are arranged in a grid at equal pitches.

The substrate 21 is, for example, a resin or ceramic insulating substrate, and a conductor pattern is formed on the light source arranging surface 21a thereof. The light source 22 includes, for example, a light emitting element 23 such as an LED (Light Emitting Diode), a phosphor layer 24, and a resin member 25. The light emitting element 23 is mounted on the light source arrangement surface 21a of the substrate 21, and the electrodes of the light emitting element 23 are electrically connected to the conductor pattern formed on the substrate 21.

The phosphor layer 24 covers the light emitting element 23, and the resin member 25 covers the phosphor layer 24. The portion of the resin member 25 that covers the vicinity of the center of the upper surface of the light emitting element 23 is recessed, and the resin member 25 having such a shape functions as a lens that gives the light source 22 a bat wing-shaped light distribution characteristic.

FIG. 6 is a diagram showing an example of the light distribution characteristics of the butt wing type. The horizontal axis represents the emission angle of the light emitted from the light source 22, and the direction perpendicular to the light source arrangement surface on which the light source 22 is arranged is 0 °. The vertical axis represents the intensity of the light emitted from the light source 22.

The butt-wing type light distribution characteristic has a first intensity peak larger than the intensity when the emission angle is 0 ° in the region where the emission angle is in the range of 0 ° to −90 °, and the emission angle is 0. It is a light distribution characteristic having a second intensity peak larger than the intensity when the emission angle is 0 ° in the region in the range of ° to 90 °.

Since the light source 22 has a butt-wing type light distribution characteristic, a uniform light emitting surface with less uneven brightness can be obtained even when the distance between the light source 22 and the cover 30 is short due to the thinning of the lamp body 10. Further, a person who puts the main surface portion (main light emitting surface) 31 of the cover 30 into the field of view can make it difficult for the person who sees the light source 22 to feel the light source 22 as a point.

The cover 30 has a translucency with respect to the light emitted by the light source 22. The cover 30 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. The cover 30 is flexible.

The lamp of the first embodiment has a power adapter 50 in addition to the lamp body 10 and the fitting adapter 40 described above.
FIG. 7 is a side view of the power adapter 50.

The power adapter 50 has a tubular portion 51 and a power supply unit 52 provided on the tubular portion 51. A plurality of mounting springs 53 having a leaf spring structure are provided on the side surface of the tubular portion 51.

The power supply unit 52 has a power supply built in the casing 57. An AC (alternating current) input terminal block 54 and a dimming terminal block 55 are provided on the upper surface of the casing 57. A DC cable 56 is connected to the AC input terminal block 54, and the DC cable 56 penetrates the inside of the casing 57 and the inside of the tubular portion 51.

The lamp of the first embodiment described above can be detachably attached to a building material such as a ceiling material or a wall material. Hereinafter, an example of attaching a lamp to a ceiling material will be described with reference to FIGS. 8 to 13.

8 and 11 show a state in which the power adapter 50 is attached to the ceiling material 300, and the fitting adapter 40 and the lamp body 10 are not attached to the ceiling material 300.

The tubular portion 51 of the power adapter 50 is formed in a cylindrical shape, and the ceiling material 300 is formed with a circular mounting hole 300a. The tubular portion 51 of the power adapter 50 is fitted into a mounting hole 300a formed in the ceiling material 300. The mounting spring 53 is arranged between the side surface of the tubular portion 51 and the inner wall of the mounting hole 300a in a deformed state from the natural state. Due to the restoring force of the mounting spring 53, the state in which the tubular portion 51 is fitted into the mounting hole 300a is maintained.

The back surface of the flange 58 provided on the outer peripheral side of the lower end opening of the tubular portion 51 comes into contact with the ceiling surface in the vicinity of the mounting hole 300a. The tubular portion 51 extends rearward (above) the flange 58, and the power supply unit 52 provided on the tubular portion 51 is arranged in the space behind the ceiling material 300. The power supply unit 52 does not project into the space below the ceiling material 300.

As shown in FIG. 8, in the lamp main body 10, the end portion 15a of the leaf spring 15 in the longitudinal direction is connected so as to be inserted into the end portion 33 of the cover 30. The end portion 33 of the cover 30 is provided at the tip of the side surface portion 32 that is folded back from the main surface portion 31.

When the lamp body 10 and the fitting adapter 40 are not attached to the power adapter 50, the end 33 of the cover 30 coupled with the end 15a of the leaf spring 15 protrudes from the back surface of the leaf spring 15. In this state, the leaf spring 15 is substantially flat and is in a natural state or a substantially natural state.

Further, as shown in FIG. 11, the fitting adapter 40 has a case 41, two slide members 42 provided in the case 41, and a spring 43 connecting the two slide members 42. A claw portion 42a having an inclined surface is provided at the tip of each slide member 42. Due to the sliding movement of the two slide members 42 accompanying the expansion and contraction of the spring 43, the claw portion 42a is retracted inside the case 41 through a through hole 44 (shown in FIG. 12) formed on the side surface of the case 41, or outside the case 41. It is possible to project to. When the spring 43 is in the natural state, the claw portion 42a projects to the outside of the case 41 as shown in FIG.

A plate-shaped fitting member 61 is provided inside the tubular portion 51 of the power adapter 50. A fitting hole 61a is formed in the fitting member 61. The diameter of the fitting hole 61a is smaller than the inner diameter of the tubular portion 51 and larger than the outer diameter of the case 41 of the fitting adapter 40.

By fitting the fitting adapter 40 provided on the back surface of the lamp body 10 into the tubular portion 51 of the power adapter 50 fitted in the mounting hole 300a of the ceiling material 300, the lamp body 10 is fitted into the ceiling material 300. It is attached to the ceiling.

As shown in FIG. 12, when the case 41 of the fitting adapter 40 is fitted into the fitting hole 61a formed in the fitting member 61 of the power adapter 50, the claw portion 42a is inclined to the inner wall of the fitting hole 61a. The surfaces come into contact. As the fitting adapter 40 is pushed further into the tubular portion 51, the force received by the claw portion 42a from the inner wall of the fitting hole 61a causes the two slide members 42 to compress the spring 43 and approach each other. Slide to move. The claw portion 42a retracts inside the case 41 to allow further pushing operation of the fitting adapter 40.

When the claw portion 42a moves to a position above the fitting member 61, the force received by the claw portion 42a from the inner wall of the fitting hole 61a is released, and the restoring force of the spring 43 separates the two slide members 42 from each other. Be urged in the direction of The claw portion 42a projects to the outside of the case 41, and as shown in FIG. 13, the lower surface of the claw portion 42a rides on the upper surface of the fitting member 61 in the vicinity of the fitting hole 61a, whereby the fitting adapter 40 and the fitting portion 42a are fitted. The lamp body 10 fixed to the adapter 40 is prevented from falling from the power adapter 50.

Before fitting the fitting adapter 40 to the power adapter 50, the DC (direct current) input connector 45 on the fitting adapter 40 side shown in FIGS. 1 and 3 is attached to the DC cable 56 on the power adapter 50 side shown in FIG. Connecting. As a result, electric power is supplied from the commercial power source to the light source 22 via the power supply unit 50. The AC power of the commercial power source is converted into DC power by the power supply unit 50 and supplied to the light source 22.

When the fitting adapter 40 described above is fitted to the power adapter 50, the leaf spring 15 provided on the back surface of the lamp body 10 is elastically deformed.

FIG. 9 shows a state in which the fitting adapter 40 is being pushed into the fitting hole 61a of the power adapter 50. As described above, the end 33 of the cover 30 coupled to the end 15a of the leaf spring 15 protrudes from the back surface of the leaf spring 15. Therefore, when the lamp body 10 is brought closer to the ceiling surface, the leaf spring 15 The end 33 of the cover 30 hits the ceiling surface before the back surface of the cover 30. At this time, the leaf spring 15 is still in a flat state, and there is a gap between the back surface of the leaf spring 15 and the ceiling surface. From this state, the fitting adapter 40 is completely fitted into the fitting hole 61a of the power adapter 50 while deforming the leaf spring 15, and the restoring force of the deformed leaf spring 15 causes the lamp body 10 to be ceilinged. Pressed against the surface.

That is, when the fitting adapter 40 is pushed further into the tubular portion 51 of the power adapter 50 from the state of FIG. 9, the leaf spring 15 is fixed to the base plate 11 with screws 16 as shown in FIG. It transforms with the part as a fulcrum. FIG. 10 shows a state in which the fitting adapter 40 is completely fitted to the fitting member 61 of the power adapter 50. In this state, the back surface of the portion of the leaf spring 15 fixed by the screw 16 comes into contact with the ceiling surface, and the portion of the leaf spring 15 on the end portion 15a side warps downward with the screw 16 as a fulcrum. Therefore, a restoring force for returning to a flat state acts on the portion of the leaf spring 15 on the end portion 15a side, and the end portion 33 of the cover 30 coupled with the end portion 15a of the leaf spring 15 is pressed against the ceiling surface. Be urged to.

When the plane size of the lamp body 10 becomes large, the end portion tends to be lowered by its own weight as compared with the central portion directly held by the fitting adapter 40 with respect to the power adapter 50. According to the present embodiment, the restoring force of the leaf spring 15 allows the end portion 33 of the cover 30 to be brought into close contact with the ceiling surface even in the lamp body 10 having a large area. This suppresses the intrusion of foreign matter into the back side (gap between the ceiling surface) of the lamp body 10.

In the state where the lamp body 10 is attached to the power adapter 50, the cushion material 18 provided on the outer edge of the back surface of the base plate 11 shown in FIG. 3 is in close contact with both of the base plate 11 and the ceiling surface. , The generation of a gap at the outer edge of the lamp body 10 is suppressed. The restoring force of the leaf spring 15 also enhances the adhesion of the cushion material 18 to the ceiling surface.

As shown in FIGS. 10 and 13, the main surface portion 31 of the cover 30 is substantially attached to the ceiling surface in a state where the lamp body 10 is attached to the power adapter 50 fitted in the ceiling material 300 via the fitting adapter 40. It becomes parallel and faces the space below the ceiling surface.

Alternatively, the lamp of the embodiment can be attached to the wall material in the same manner as the attachment method to the ceiling material. When the lamp body 10 is attached to the wall material, the main surface portion 31 of the cover 30 is substantially parallel to the wall surface and is directed to the lateral space of the wall surface.

Further, the plurality of light sources 22 in the light source module 20 are arranged over an area wider than the area of the mounting hole 300a formed in the ceiling material 300 and the opening area of the tubular portion 51 of the power adapter 50, and are fitted in the lamp body 10. The light source 22 is also arranged in the area overlapping the adapter 40. Therefore, in the main surface portion (main light emitting surface) 31, the central portion, which is a region overlapping the mounting hole 100a and the fitting adapter 40, can also be illuminated, and the light emitting surface can be obtained over a wide area.

According to the first embodiment described above, it is not necessary to make a square hole in the building material according to the shape and size of the lamp body 10, the construction on the building material is smaller than the size of the lamp body 10, and the power adapter 50 You only need to make one mounting hole according to the size of. The power adapter 50 can be easily attached to and detached from the mounting hole with a single touch using the mounting spring 53. Further, by attaching / detaching the fitting adapter 40 to / from the power adapter 50, the lamp body 10 can be attached / detached to / from the building material with one touch. According to such a first embodiment, the construction man-hours for attaching the lamp to the building material can be significantly reduced.

Further, since the various types of lamp main body 10 can be easily attached to and detached from the power adapter 50 common to these with one touch, it is possible to change to another type of lamp main body 10 without any trouble. When changing the lamp body 10, it is not necessary to remove the common power adapter 50 from the building material, and only the lamp body 10 may be attached to and detached from the power adapter 50 via the fitting adapter 40.

Before fitting the mounting bracket 160 into the mounting hole 300a of the ceiling material 300, the power supply unit 150 shown in FIG. 16 is arranged on the back side of the ceiling material 300, if necessary. The power supply unit 150 is passed through the mounting hole 300a to the back side of the ceiling material 300, and is arranged at a position on the back side of the ceiling material 300 so as not to overlap the mounting hole 300a.

Alternatively, when the power supply unit 150 already installed on the back side of the ceiling material 300 is used as it is, the work of installing the power supply unit 150 on the back side of the ceiling material 300 becomes unnecessary.

As shown in FIG. 16, the power supply unit 150 has terminal blocks 152 and 153 that can be connected to an external power supply (commercial power supply). An electric cable 151 is led out from the power supply unit 150. The terminals of the terminal blocks 152 and 153 are electrically connected to the circuit board of the power supply unit 150, and the electric cable 151 is electrically connected to the circuit board. A power supply side connector 151a is provided at the end of the electric cable 151.

In the state before the lamp body 110 is attached to the ceiling material 300, the electric cable 151 is passed through the mounting hole 300a of the ceiling material 300 and the opening 164 inside the mounting bracket 160 fitted in the mounting hole 300a to supply power. The side connector 151a is located on the front side of the ceiling material 300.

The worker who installs the lamp 100 brings the lamp 100 close to the ceiling material 300, holds the lamp 100 with one hand, and holds the power connector 151a of the electric cable 151 hanging from the mounting hole 300a with the other hand. Grasp and connect the power supply side connector 151a to the lamp side connector 143 fixed to the upper surface of the fitting adapter 140 provided on the back surface of the lamp body 110.

After connecting the power supply side connector 151a to the lamp side connector 143, the fitting adapter 140 is fitted into the opening 164 inside the mounting bracket 160 fitted in the mounting hole 300a of the ceiling material 300.

FIG. 22 is a perspective view showing a fitting structure of the mounting bracket 160 and the fitting adapter 140.
FIG. 23 is a cross-sectional perspective view showing the fitting structure of the mounting bracket 160 and the fitting adapter 140.

The fitting adapter 140 has an upper case 141, a lower case 142, two slide members 145, and a spring 147 that connects the two slide members 145.

At the tip of each slide member 145, a claw portion 144 having an inclined surface is provided. Due to the sliding movement of the two slide members 145 due to the expansion and contraction of the spring 147, the claw portion 144 retracts inside the cases 141 and 142 through the opening formed between the upper case 141 and the lower case 142, or the cases 141 and 142. It is possible to project to the outside of.

22 and 23 show a state in which the claw portion 144 protrudes to the outside of the cases 141 and 142 and rides on the upper surface of the receiving plate 162 of the mounting bracket 160. As shown in FIG. 23, the stopper 141a protruding downward from the upper case 141 is located in the recess 146 formed on the upper surface of the slide member 145, and the two slides are brought into contact with the wall surface of the stopper 141a and the recess 146. The movement of the members 145 in the direction away from each other is restricted.

Normally, the claw portion 144 projects to the outside of the cases 141 and 142. When the fitting adapter 140 is fitted inside the mounting bracket 160, the inclined surface of the claw portion 144 is brought into contact with the inner peripheral wall of the flange 161 of the mounting bracket 160 and the inner peripheral wall of the receiving plate 162. The force received by the claw portion 144 from the inner peripheral wall of the flange 161 and the inner peripheral wall of the receiving plate 162 causes the two slide members 145 to compress the spring 147 and slide so as to approach each other. The claw portion 144 retracts inside the cases 141 and 142, allowing the fitting adapter 140 to be fitted inside the mounting bracket 160.

Then, when the claw portion 144 moves to a position above the receiving plate 162, the force received by the claw portion 144 from the inner peripheral wall of the receiving plate 162 is released, and the two slide members 145 are separated from each other by the restoring force of the spring 147. Be urged in the direction. The claw portion 144 projects to the outside of the cases 141 and 142, and the lower surface of the claw portion 144 rides on the upper surface of the receiving plate 162. As a result, the fitting adapter 140 and the lamp body 110 fixed to the fitting adapter 140 are prevented from falling from the mounting bracket 160.

In a state where the fitting adapter 140 is fitted to the mounting bracket 160, the cushion material 113 provided on the back surface of the metal plate 111 shown in FIG. 17 comes into close contact with the front surface of the ceiling material 300. As shown in FIG. 14, the main surface portion 131 of the cover 130 is parallel to the front surface of the ceiling material 300 and is directed to the space below the ceiling material 300.

Alternatively, the lamp 100 of the second embodiment can be attached to the wall material in the same manner as the attachment method to the ceiling material 300. When the lamp 100 is attached to the wall material, the main surface portion 131 of the cover 130 is parallel to the wall surface and is directed to the lateral space of the wall material.

The plurality of light sources 22 in the light source module 20 are arranged over an area wider than the area of the mounting hole 300a of the ceiling material 300 and the area of the opening 164 of the mounting bracket 160, and are also light sources in the area overlapping the fitting adapter 140 in the lamp body 110. 22 are arranged. Therefore, in the main surface portion (main light emitting surface) 131, the central portion, which is a region overlapping the mounting hole 300a and the fitting adapter 140, can also be illuminated, and the light emitting surface can be obtained over a wide area.

Further, in a state where the fitting adapter 140 is fitted to the mounting bracket 160, as shown in FIG. 16, the upper surface of the fitting adapter 140 and the connection portion between the power supply side connector 151a and the lamp side connector 143 are the ceiling material 300. It is exposed in the space on the back side. The upper surface of the fitting adapter 140 is exposed in the space behind the ceiling material 300, and is fixed to the mounting bracket 160. The power supply unit 150 is arranged so as not to overlap the fitting adapter 140 and does not cover the fitting adapter 140. Therefore, the heat generated by the light source module 20 can be dissipated to the space behind the ceiling material 300 through the fitting adapter 140.

The operator fits the fitting adapter 140 inside the mounting bracket 160 while manually pushing up the central portion (place where the fitting adapter 140 is arranged) on the front surface of the main surface portion 131 of the cover 130.

At this time, as shown in FIG. 24, the central portion of the main surface portion 131 of the cover 130 bends so as to be recessed toward the fitting adapter 140 side, and the back surface portion of the main surface portion 131 hits the protrusion 181. The load applied to the main surface portion 131 is applied to the fitting adapter 140 through the convex portion 181 so that the fitting adapter 140 can be fitted into the mounting bracket 160. As shown in FIG. 27, since the plurality of convex portions 181 are evenly arranged around the fitting adapter 140, the load can be applied evenly and evenly to the fitting adapter 140, and the fitting adapter can be easily applied. The 140 can be fitted into the mounting bracket 160.

When the main surface portion 131 of the cover 130 is pushed, the convex portion 181 acts as a stopper to regulate further displacement of the main surface portion 131, and the main surface portion 131 does not hit the light source 22. Therefore, damage to the cover 130 and the light source 22 can be prevented.

Also in the first embodiment, as shown in FIG. 27, for example, four convex portions 181 are provided around the arrangement portion of the fitting adapter 40. Therefore, when the fitting adapter 40 shown in FIGS. 12 to 13 is fitted into the power adapter 50, the back surface of the main surface portion 31 of the cover 30 hits the convex portion 181. The load applied to the main surface portion 31 is applied to the fitting adapter 40 through the convex portion 181 so that the fitting adapter 40 can be fitted into the power adapter 50. Further, the convex portion 181 can prevent the cover 30 from being damaged by the collision with the light source 22.

Next, a method of removing the lamp 100 from the ceiling material 300 will be described.

As shown in FIG. 17, a removing member 112 is provided on the back surface of the metal plate 111. One end 112c of the removal member 112 is exposed on the side surface of the lamp body 110, and the operator can grasp the one end 112c of the removal member 112 with a finger or a jig while the lamp body 110 is attached to the ceiling material 300. .. The other end of the removal member 112 is connected to the slide member 145 of the fitting adapter 140.

25 and 26 are perspective views showing a connecting structure of the fitting adapter 140 and the removing member 112.
FIG. 25 shows a state in which the upper case 141 of the fitting adapter 140 is removed.
FIG. 26 is a perspective view of the connection structure of the removal member 112 and the slide member 145 as viewed from the back side by further removing the lower case 142 in FIG. 25.

The removal member 112 and the slide member 145 are connected via two arm members 148. Each arm member 148 can rotate around the shaft portion 142a provided on the lower case 142 as a fulcrum.

A through hole 148a is formed at one end of each arm member 148, and a pin 112a provided at the other end of the removal member 112 is engaged in the through hole 148a.

An elongated hole 112b is formed in the removing member 112, and a screw 115 is located in the elongated hole 112b. The screw 115 is attached to the metal plate 111. The operator can slide the removal member 112 along the longitudinal direction of the removal member 112 by pulling the one end portion 112c of the removal member 112 with, for example, a jig. At this time, the sliding movement of the removing member 112 is guided by the contact between the inner wall of the elongated hole 112b and the screw 115.

When the removal member 112 is pulled in the direction in which one end 112c of the removal member 112 protrudes from the lamp body 110, a pair of arm members 148 engaged with the pin 112a of the removal member 112 rotate around the shaft portion 142a as a fulcrum. By the rotation of the arm member 148, the other end portion 148b of the arm member 148 shown in FIG. 26 pushes the protruding portion 149 provided on the lower surface of the slide member 145. As a result, the two slide members 145 compress the spring 147 and slide in the direction of approaching each other.

By the sliding movement of the slide member 145, the state in which the claw portion 144 is mounted on the receiving plate 162 of the mounting bracket 160 shown in FIG. 23 is released, the fitting adapter 140 is disengaged from the mounting bracket 160, and the lamp body 110 is attached to the ceiling material. It can be removed from 300.

One end 112c of the removal member 112 is bent inside the lamp body 110, and a jig can be hooked on the one end 112c. The position of one end 112c of the removal member 112 is aligned with the notch formed on the side surface of the cover 130, and is exposed on the side surface of the lamp body 110.

The removal member 112 is a metal member, and the metal member is painted in the same color as or close to the color of the cover 130 (for example, milky white). The removal member 112 is painted white, for example. Therefore, especially when the lamp is not lit, one end 112c of the removal member 112 does not stand out on the side surface of the lamp main body 110, and the appearance quality is not impaired.

The fitting / detaching mechanism of the fitting adapter 140 with respect to the mounting bracket 160 in the second embodiment is also applied to the fitting / detaching mechanism of the fitting adapter 40 with respect to the power adapter 50 in the first embodiment.

According to the second embodiment described above, it is not necessary to make a square hole in the building material according to the shape and size of the lamp body 110, and the construction on the ceiling material 300 is smaller than the size of the lamp body 110 and fits. It is only necessary to make one mounting hole 300a according to the size of the combined adapter 140. Then, the lamp body 110 can be easily attached to the ceiling material 300 by fitting the fitting adapter 140 into the mounting bracket 160 fitted in the mounting hole 300a.

The lamp side connector 143 is fixed to the upper surface of the fitting adapter 140 instead of being connected to one end of the cable and hanging around. On the other hand, the power supply side connector 151a is led out from the power supply unit 150 by the electric cable 151. Therefore, the power supply side connector 151a is positioned at the worker's hand on the front side of the ceiling material 300 through the mounting hole 300a of the ceiling material 300 and the opening 164 of the mounting bracket 160, and the worker grasps the power supply side connector 151a with one hand. While supporting the lamp 100 with one hand attached to the main surface 31 of the cover 30 of the lamp 100, the power supply side connector 151a can be connected to the lamp side connector 143. It is not necessary to grasp the lamp side connector 143 itself by hand. Therefore, even if the flat size of the lamp main body 110 is increased, one worker can easily make an electrical connection between the power supply unit 150 and the lamp 100 and attach the lamp 100 to the ceiling material 300.

When removing the lamp 100 from the ceiling material 300, one hand is attached to the main surface 31 of the lamp 100 to support the lamp 100, and one end of the above-mentioned removal member 112 is held by the other hand using, for example, a jig. By pulling, the engagement between the claw portion 144 of the fitting adapter 140 and the mounting bracket 160 is released, and the lamp 100 can be removed from the ceiling material 300. After that, while maintaining the state in which the lamp 100 is supported by one hand, the other hand can be moved from the removal member 112 to the power supply side connector 151a, and the power supply side connector 151a can be pulled out from the lamp fixture side connector 143. That is, the removal of the lamp 100 from the ceiling material 300 and the disconnection of the electrical connection between the power supply unit 150 and the lamp 100 can be easily performed by one operator.

According to such a second embodiment, since various types of lamp main bodies 110 can be easily connected to the power supply unit 150 common to them with one touch, it is possible to connect to other types of lamp main bodies 110 without any trouble. It can be changed. When changing the lamp body 110, it is not necessary to remove the common power supply unit 150 from the ceiling material 300.

Further, the mounting bracket 160 is formed in an annular shape, and the upper portion thereof is opened without being blocked. Therefore, after connecting the power supply side connector 151a to the lamp side connector 143, when fitting the fitting adapter 140 into the mounting bracket 160, the mounting bracket does not pinch or catch the electric cable 151 somewhere. It can be retracted to the space above the 160, and the fitting work of the fitting adapter 40 to the mounting bracket 160 is not hindered.

Next, as the third embodiment, when constructing a building such as an office building, a factory, or a commercial facility, the lighting fixture described in the first embodiment or the lighting fixture 100 described in the second embodiment may be used. The process of installing the [lighting fixture] will be described. Therefore, first, the conventional process in the construction of such a building will be described. FIG. 28 is a flow chart for explaining the flow of lighting installation in the process until the conventional building is constructed. Here, a building having a multi-story structure, a passage and a living room, such as a general office building, is targeted. In the construction of a large-scale building such as an office building, a general contractor undertakes an order for the construction work and manages the entire construction work performed by various contractors.

First, a designer or designer designs the building (step S1). In this process, the layout of the passage and the living room is decided, and the overall design of the building 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 based on the determined design, and foundation work is carried out (step S2). In this process, stable ground that can withstand the load of the building is secured by pile construction and earthwork. Here, mainly the workers of the civil engineering contractor perform the work. Not only the workers of the civil engineering contractor, but also the workers of other contractors are doing the work.

Next, the skeleton construction for forming the skeleton of the building on the stable ground is performed (step S3). As for the skeleton work, if it has a foundation part or a basement floor, it starts with underground work such as the basement floor and proceeds to the ground floor. The skeleton of the entire building is completed by placing concrete, building columns, and assembling steel frames. In addition, concrete will be placed on the outer walls, rooftops, floors of each floor, etc.

Further, in the skeleton work, an insert is embedded in order to lower the 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 work and the workers of the jump, earthwork, and concrete work perform the work. Next, the exterior work of the building is carried out (step S4). Tiled exterior walls, window sashes, windowpanes, curtain walls, etc. can be installed. In addition, painting is also performed.

Next, interior work is performed (step S5). In interior work, ceilings, walls, and floors are created. In the ceiling work to install the ceiling, the hanging bolts are lowered from the ceiling insert provided in the skeleton work of step S3, and the base material combined with the lightweight steel frame is used to form the ceiling surface such as the ceiling board and the ceiling base material. Ceiling material is attached. Suspended materials such as hanging bolts and hangers and diagonal members are used to support the ceiling material, which takes risk prevention measures such as the ceiling plate falling off.

For example, in Japan, the Building Standards Law and the Enforcement Ordinance provide provisions to prevent such ceiling dropouts. 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 or the like, are stipulated. Depending on the size and weight of the lighting fixture, some can be installed on the ceiling without being fixed to the hanging material, and some have fixed by the hanging material.

The ceiling insert for fixing the suspension bolt can be fixed by driving an anchor to the concrete after the concrete is placed, instead of installing the ceiling insert at the time of placing the concrete. However, considering efficiency and safety, it is preferable to install it in advance, and in places where it is known that suspension materials will be installed, the placement of ceiling inserts is decided at the design stage, and concrete is placed. It is desirable to be embedded at the time of.

Further, in the interior work, before the ceiling is stretched, that is, before the formation of the ceiling by the ceiling material is completed, the pipes and the air-conditioning ducts are hung and the electric wires and the like are passed through the pipes. Therefore, a space necessary for installing electrical wiring, ducts, air conditioners, etc. is provided behind the ceiling. Furthermore, an opening is provided in the ceiling material according to the place where lighting and air conditioning are installed. Here, work such as installing a duct in the ceiling and fixing the ceiling material with a hanging material is performed by a worker of a contractor who performs interior work. On the other hand, since there is a risk of electric shock or the like, the work of providing the electrical wiring is performed by a professional worker who can perform the electrical work.

In many cases, it is assumed that the ceiling construction worker who installs the ceiling and the wiring construction worker who passes the electrical wiring behind the ceiling are different people. In Japan, electrical work such as wiring work by persons who are not qualified as electricians is not permitted. In this way, in the construction of buildings, workers are dispatched from various specialized contractors, and each of them performs specialized work to give consideration to safety.

In the present specification, a worker of a contractor who prepares a ceiling material for construction of a building and performs ceiling work is referred to as a ceiling installation worker. In addition, a worker of a contractor who prepares electrical wiring for construction of a building and performs wiring work is called a wiring work worker. The construction of each process in the construction of a building is usually carried out by a plurality of workers. Therefore, the ceiling installation worker is not limited to one worker, but refers to one or more workers who perform ceiling construction in the construction of a building. The same applies to wiring workers.

Next, when the interior work is completed and the floor, walls, and ceiling are completed, the installation work is performed (step S6). In the installation work, the equipment required for actually using the building will be 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.

Even in the installation work of lighting, it is necessary to electrically connect the lighting fixtures, so the work by a qualified electrician is required. The place where the lighting is installed is not limited to the ceiling, but the lighting fixtures installed on the ceiling are usually connected to the wiring prepared behind the ceiling by a qualified electrician and electrically connected. Will be done. Even when installing air-conditioning equipment on the ceiling in air-conditioning equipment construction, it is connected to the wiring prepared behind the ceiling by a qualified electrician.

Normally, in a living room of a building such as an office building, large lighting fixtures and air conditioners arranged on the ceiling are fixed by hanging materials. Therefore, the worker who installs such a large lighting fixture or air conditioner should also fix the large lighting fixture or air conditioner to the hanging material suspended from the ceiling insert and install it on the ceiling. become.

In time for the installation work of the lighting, the manufacturer of the lighting fixture manufactures the lighting fixture 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, and distribution boards, interphones, fire alarms, etc., not limited to lighting equipment, and is necessary for construction. Supply the required amount of electrical equipment materials (step S8). In the present specification, an employee of a company that manufactures or delivers a luminaire is referred to as a luminaire supplier.

In the installation work process, the lighting installation work and the air conditioning installation work are performed separately. It is possible to perform both installation work at the same time, or the same person can perform both installation work, but it is more common to share the work in consideration of work efficiency. The building is constructed in this way.

In this specification, the term "installation worker" refers to one or more workers who perform installation work such as lighting and air conditioning, and the same person as described above performs the installation work of lighting and air conditioning. It shall be possible to include the case of doing so. On the other hand, the term "lighting installation work worker" refers to one or more workers who perform lighting installation work and does not refer to air conditioning installation work. The term "air-conditioning installation work worker" refers to one or more workers who perform air-conditioning installation work and does not refer to lighting installation work.

Next, as a third embodiment, a process of constructing a building and a process of installing a lighting fixture 200 in this construction will be described. As the lighting fixture 200 here, the lighting fixture described in the first embodiment or the lighting fixture 100 described in the second embodiment can be used. The building 210 according to the third embodiment has a structure of a plurality of floors, and has a passage and a living room. It may be a one-story building. FIG. 29 is a schematic view showing an example of the structure of a living room on a specific floor of the building 210.

The building 210 forms a living room space with a floor 220, a wall 221 and a ceiling 222, and a window 223. It should be noted that a living room without a window 223 and having only a wall 221 on the side surface may be used. Further, a plurality of lighting fixtures 200 and a plurality of air conditioners 230 are installed on the ceiling. The number of air conditioners 230 may be one.

Here, some ceiling fixtures such as lighting fixtures and air conditioners installed on the ceiling need to be directly fixed by a hanging material and some do not. For example, small ceiling fixtures such as surveillance cameras, downlights, emergency lights, or smoke detector sensors are installed without being fixed by being directly connected to hanging materials such as hanging bolts or diagonal members. NS. Since such a small ceiling installation device has a small load applied to the ceiling material, it is permitted to install it without the need for a hanging material. Hereinafter, such a ceiling installation device is referred to as a ceiling installation device that does not require fixing with a hanging material.

On the other hand, the ceiling-mounted base lighting, the ceiling-embedded base lighting, the air conditioner 230, and the like are fixedly installed by being directly connected to the hanging material. Since such a ceiling-installed fixture has a large load applied to the ceiling material, if it is not fixed by a hanging material, there is a high risk that it will fall off in the event of an earthquake, for example. Therefore, the ceiling installation fixture itself is supported by the suspension material, instead of the installation structure in which all the loads are applied to the ceiling material. Hereinafter, such a ceiling installation device is referred to as a ceiling installation device that requires fixing with a hanging material.

For example, in the case of a building such as an office building, small ceiling fixtures such as downlights are installed for lighting in a narrow space such as a passage, and large lighting fixtures such as base lighting are installed in a large space such as a living room. It is possible that it will be done. It is possible that a small lighting fixture is installed in a part of the living room, but in terms of the number of lighting fixtures installed in the entire living room, the majority are large lighting fixtures.

The lighting fixture 200 according to the present embodiment has a performance equivalent to that of base lighting in terms of the performance of the lighting fixture, and may be a lighting fixture that does not require fixing with a hanging material in the installation work of the lighting. can. That is, the lighting fixture 200 is a lightweight large lighting fixture that is large enough to be handled as equivalent to base lighting, but lightweight enough to require no hanging material.

Here, the lightweight large-sized lighting fixture in the present specification means that the total luminous flux is 2500 lm or more, the area of the light emitting surface that is the surface closest to the floor is 45000 mm ² or more, or 100 or more light source elements are arranged. It shall refer to a lighting fixture that satisfies at least one of the above. Alternatively, in addition to this, the characteristics of the lightweight large luminaire may be further specified under the condition that the weight is 0.5 kg or more and less than 2.5 kg.

Next, the process until the lighting fixture 200 is installed in the construction of the building 210 will be described. It should be noted that the points different from the process up to the construction of the building already described with reference to FIG. 28 will be described in detail, and the overlapping points will be simplified or omitted.

Since the lighting fixture 200 does not need to be fixed by the hanging material 270, the designer or the designer does not need to determine the arrangement position of the hanging material according to the installation position of the lighting fixture 200 in step S1. Further, when the ceiling insert is provided and the arrangement position of the suspension material 270 is determined, and then the arrangement position of the base lighting which needs to be fixed by the conventional suspension material is changed, it is necessary to newly install the suspension bolt. In the case of the lighting fixture 200, this is not necessary. Therefore, the designer or the designer can flexibly change the installation location of the lighting fixture 200 even after the construction has progressed to some extent.

The steps from step S2 to step S4 are almost the same as those already described. Next, in the interior work of step S5, the ceiling work for providing the ceiling is performed. In addition, the wiring arranged behind the ceiling is passed to a position higher than the ceiling before or after the ceiling is stretched. FIG. 30 shows an example of the attic in a state where the ceiling work has been performed.

As shown in FIG. 30, the attic has a space in which the upper surface and the side surface are formed by the skeleton 224 in which concrete is cast, and the lower surface is formed by the ceiling 222 in which the ceiling material 300 is arranged. Further, each ceiling member 300 forming the ceiling 222 is fixed and supported by a hanging member 270 connected to the ceiling insert of the skeleton 224. Since the drawing becomes complicated, the display of the hanging member 270 is partially omitted in FIG. 30. In the space behind the ceiling, there are wiring 240 and wiring 241 provided through pipes. This wiring is provided based on the design drawing according to the number of electrical connection devices such as lighting and air conditioning installed behind the ceiling. The ceiling 222 is provided after a sufficient number of wires are prepared to supply power to the electrical connection device.

Here, the work of passing the wiring through the ceiling is performed by a wiring work worker who is qualified as an electrician. Further, in this work, the wiring 240 to be connected to the lighting fixture 200 is provided with a connector by a wiring work worker who is qualified as an electrician. The connector is an example of an electric shock prevention connection device for preventing electric shock in the connection work between the electric connection device for electrically connecting the electric connection device and the wiring 240.

If you have an electric shock prevention connection device such as a connector, you can connect the wiring 240 to the lighting fixture 200 even if you are not a qualified electrician. In the example of FIG. 30, the wiring 240 to be connected to the lighting fixture 200 is provided with a connector, while the wiring 241 to be connected to the air conditioner 230 is not provided with an electric shock prevention connecting device such as a connector. .. Therefore, in compliance with the laws and regulations of Japan at the time of filing, the work of connecting the wiring 241 to the air conditioner 230 must be performed by a person who is qualified as an electrician. Since the figure becomes complicated, the display of the wiring 240 is partially omitted in FIG.

In this way, in the work of providing the wiring arranged behind the ceiling, among the plurality of wiring arranged behind the ceiling, the lighting fixture 200 is electrically connected to the lighting fixture 200 which is not fixed by the hanging material when it is installed on the ceiling. As the wiring for this purpose, the work of providing the wiring 240 with the electric shock prevention connecting device such as a connector is performed.

Further, since the air conditioner 230 is fixed by the suspension material, the suspension material 271 is provided as the suspension material for fixing the air conditioner 230. At the time of FIG. 30, since the air conditioner 230 has not been attached yet, the suspension member 271 does not fix the air conditioner 230.

The ceiling material 300 is provided with an opening for installing ceiling installation fixtures such as an air conditioner 230 and a lighting fixture 200. The square opening shown in FIG. 30 is an opening for the air conditioner 230. Further, the circular opening is a mounting hole 300a for the lighting fixture 200. In the example of FIG. 30, out of a total of 18 ceiling materials 300 of 6 × 3, openings for installing the air conditioner 230 in each of the two ceiling materials 300 illuminate each of the 12 ceiling materials 300. An opening for installing the lamp 200 is provided.

As shown in FIG. 30, the mounting hole 300a provided for installing the lighting fixture 200 is smaller than the ceiling material 300. Further, the opening is sufficiently smaller than the light emitting surface of the lighting fixture 200. In this regard, downlights and emergency luminaires, in contrast, have openings comparable to the size of their luminaires. In the lighting fixture 200, the mounting hole 300a can be reduced to 1/3 or less of the area of the light emitting surface. Alternatively, it can be 1/5 or less. Alternatively, it can be 1/10 or less.

The mounting hole 300a for installing the lighting fixture 200 is formed, for example, in a circular shape having a diameter of 10 cm to 15 cm. Further, the shape of the mounting hole 300a does not have to be circular, and may be a polygon having a maximum diameter of 15 cm or less. Further, it may be determined based on the size and shape of the power adapter 250 and the like. It is preferable that the mounting hole 300a has a size sufficient for the arm of the worker to pass through so that the wiring 240 can be picked up from the living room side for mounting the lighting fixture 200.

The ceiling material 300 does not have to be provided with an opening in advance. It is common that a ceiling material 300 having no opening is prepared, and a worker makes a hole in the ceiling material 300 to provide an opening at a site where interior work is performed. The work of appropriately providing an opening in the ceiling material 300 having no opening may be performed. The shape of the opening to be prepared may differ depending on what kind of ceiling installation equipment is installed. Therefore, the opening may be provided when the ceiling material 300 is fixed by the hanging material 270 and attached to the ceiling, or may be provided after the ceiling is formed.

After the ceiling 222 is provided in this way, the lighting installation work is performed in the equipment work in step S6. 31 and 32 are diagrams showing the connection relationship between the wiring 240 with a connector, the ceiling material 300, the power adapter 250, and the lighting fixture 200. The lighting installation work can be performed even by a person who is not qualified as an electrician.

When the ceiling 222 is provided in the building 210, the living room space, which is the space forming the living room shown in FIG. 29, and the attic space, which is the space forming the attic shown in FIG. It can be treated as a distinct space. Here, the presence or absence of openings in the ceiling material 300 is not considered. Specifically, when the ceiling 222 is formed by the ceiling material 300 having no opening in the building 210, the space having the ceiling 222 as a part forming the space and above the ceiling 222 is the ceiling. A back space, a space having a ceiling 222 as a part forming the space, and a space below the ceiling 222 is distinguished as a living room space.

First, a lighting fixture 200 and a power adapter 250 are prepared in the living room space by a worker existing in the living room space. The lighting fixture 200 is connected to the power adapter 250 by a worker existing in the living room space by fitting the mounting adapter 211 of the lighting fixture 200 into the power adapter 250. Further, by connecting to the DC harness 280 of the power adapter 250, the lighting fixture 200 receives the power supply of the DC power supply from the power adapter 250. For example, a DC voltage of 100 V is supplied. The connection with the DC harness 280 can also be made by a worker who is not qualified as an electrician. The fitting adapters 40 and 140 correspond to one form of the mounting adapter 211. Further, the power adapter 50 corresponds to one form of the power adapter 250. Further, the DC cable 56 corresponds to one form of the DC harness 280.

Since AC power is supplied via the wiring 240, the power adapter 250 has an AC / DC conversion function. Further, the power adapter 250 has an AC terminal block 260 as a connection portion for electrically connecting to the wiring 240 with a connector via the connector. A worker existing in the living room space passes his arm through the opening, pulls the wiring 240 with a connector provided in the ceiling space from the opening, and pulls it into the living room space. Then, the connector of the wiring 240 with a connector and the AC terminal block 260 are connected in the living room space. The AC input terminal block 54 corresponds to one form of the AC terminal block 260.

The power adapter 250 is a dimming terminal as a connection portion for connecting to a dimming driver device that controls dimming in case the lighting fixture 200 has a dimming function for adjusting the intensity and color tone of light emission. It has a pedestal 262. When using the lighting fixture 200 having no dimming function, the dimming terminal block 262 is unnecessary.

In this way, the wiring 240 with a connector and the power adapter 250 arranged in the attic space above the ceiling 222 formed through the opening provided in the ceiling material 300 are connected by the connector of the wiring with a connector. The work of connecting is done. Further, the work of electrically connecting the lighting fixture 200 prepared in the living room space below the formed ceiling 222 and the power adapter 250 is performed.

Further, the power adapter 250 has a fastener 290, and a worker existing in the living room space installs the power adapter 250 on the ceiling material 300 by the fastener 290. The fastener 290 has a spring property (elasticity), and the fastener 290 is passed through the opening of the ceiling material 300 from the ceiling surface side (living room space side). After penetrating, the fastener 290 is applied to the back surface of the ceiling material 300, and therefore a load is applied to the ceiling material 300. When the lighting fixture 200 is attached to the ceiling 222, the load of the lighting fixture 200 of 1 and the power adapter 250 of 1 is applied to the ceiling material 300 of 1. The mounting spring 53 corresponds to one form of the fastener 290. Further, the fastener 290 is not limited to a structure having a spring property, and may be a structure in which a load is applied to the ceiling material 300.

Either the work of connecting the wiring 240 with the connector and the power adapter 250 and the work of connecting the power adapter 250 and the lighting fixture 200 may come first. Further, the work of attaching the power adapter 250 to the ceiling material 300 may be performed before or after the lighting fixture 200 is connected to the power adapter 250.

The method of attaching the lamp fixture described in the first embodiment is a method of attaching the power adapter 50 to the ceiling material 300 and then attaching the fitting adapter 40 of the lighting fixture 200 to the power adapter 50. That is, this is a specific example in which a method of connecting the wiring 240 with a connector and the power adapter 250 and attaching the power adapter 250 to the ceiling material 300 before connecting the power adapter 250 and the lighting fixture 200 is described in detail.

Further, as shown in FIG. 33, instead of attaching the fastener 290 of the power adapter 250 to the opening of the ceiling material 300, the power adapter 251 is arranged behind the ceiling, and the fastener 291 of the lighting fixture 200 is attached to the ceiling material 300. It may be attached to the opening. The power supply unit 150 corresponds to one form of the power adapter 251.

In this case, a worker existing in the living room space passes his arm through the opening and pulls the wiring 240 with a connector provided in the ceiling space from the opening to pull it into the living room space. Then, the connector of the wiring 240 with a connector and the AC terminal block of the power adapter 251 are connected in the living room space. The terminal block 152 or 153 corresponds to one form of an AC terminal block.

Then, the worker existing in the living room space arranges the power adapter 251 connected to the wiring 240 with the connector behind the ceiling through the opening through which the wiring 240 with the connector to be connected passes. The wiring 240 with a connector also returns to the ceiling, and the DC harness 281 of the power adapter 251 pops out from the opening into the living room space. The lighting fixture 200 is connected to the DC harness 281 and is supplied with power. The electric cable 151 corresponds to one form of the DC harness 281. Further, the lighting fixture 200 has a fastener 291 instead of the power adapter 251 and is attached to the ceiling 222 by passing the fastener 291 through the opening and hanging it on the ceiling of the ceiling material 300.

In this way, the work of installing the lighting fixture 200 on the ceiling material 300 is performed by passing the fastener 290 of the power adapter 250 electrically connected to the wiring 240 with the connector through the opening of the ceiling material 300. Alternatively, the work of installing the lighting fixture 200 on the ceiling material 300 is performed by passing the fastener 291 of the lighting fixture 200 electrically connected to the wiring 240 with the connector through the opening of the ceiling material 300.

Further, the work of connecting the wiring 240 with the connector and the power adapter 251 by the connector of the wiring 240 with the connector and arranging the power adapter 251 electrically connected to the wiring 240 with the connector in the space behind the ceiling is performed. The work of installing the lighting fixture 200 on the ceiling material 300 is performed.

As described in the second embodiment, the lighting fixture 200 may be attached to the ceiling material 300 via a mounting bracket 160 having a mounting spring 163 as a fastener. In this case, after performing the work of arranging the power adapter 251 electrically connected to the wiring 240 with the connector in the space behind the ceiling, the mounting bracket 160 is installed on the ceiling material 300 by the fastener.

Further, the DC harness 281 of the power adapter 251 arranged in the attic space is pulled into the living room space through the opening 164 of the mounting bracket 160, and the DC harness 281 is connected to the lighting fixture 200 in the living room space to form the power adapter 251. The lighting fixture 200 is electrically connected. Further, by electrically connecting to the power adapter 251, the lighting fixture 200 is electrically connected to the wiring 240 with a connector.

Further, the lighting fixture 200 is installed on the mounting bracket 160 in a state where the power adapter 251 and the lighting fixture 200 are electrically connected. The claw portion 144 of the fitting adapter 140 as the mounting adapter 211 corresponds to a fastener for mounting the lighting fixture 200 on the mounting bracket 160. That is, the fastener of the mounting bracket 160 is used for installation on the ceiling material 300, and the fastener of the lighting fixture 200 is used for installation on the mounting bracket 160.

In this way, the fastener of the lighting fixture 200 is passed through the opening 164 of the mounting bracket 160, and the installation work of the lighting fixture 200 on the ceiling material 300 is performed via the mounting bracket 160. The mounting bracket 160 can be said to be a form of a mounting auxiliary member that assists the installation of the lighting fixture 200 on the ceiling material 300. The mounting auxiliary member may have, for example, the same shape and structure as the mounting bracket 160, and may be made of a material other than metal.

The power adapter 251 is arranged behind the ceiling of the ceiling material 300 having the opening in the vicinity of the opening through which the power adapter 251 passes. Therefore, when the lighting fixture 200 of 1 is attached to the ceiling material 300 of 1, the power adapter 251 of 1 connected to the lighting fixture 200 is arranged on the ceiling material 300 of 1. Therefore, as in the first embodiment, the power adapter 251 of 1 and the lighting fixture 200 of 1 become the load applied to the ceiling material 300 of 1.

The power adapter 251 may be arranged on the ceiling material 300 to which the lighting fixture 200 cannot be attached. In the example of FIG. 33, the power adapter 251 may be moved so as to be arranged on the ceiling material 300 having no opening. By doing so, the load applied to the ceiling material 300 of 1 can be reduced. For example, a total of two power adapters 251 arranged on the two ceiling materials 300 in FIG. 33 may be arranged on one ceiling material having no opening. However, if the distance to the ceiling material 300 is too long to reach even if the arm is extended, the work of arranging the power adapter 251 may be difficult or troublesome.

As described above, since the installation work of the lighting fixture 200 does not have the fixing by the hanging material 270, it is sufficient that the opening is provided so that the wiring 240 with the connector in the ceiling can be pulled out into the living room space. In other words, in order to install the lighting fixture 200 on the ceiling 222, an opening having a size that allows an arm to pass through is sufficient. On the other hand, in the case of a lighting fixture that requires the work of fixing with the hanging material 270, it is a difficult task to attach the lighting fixture from the living room space side by using only the opening having a size that allows the arm to pass through.

Further, by preparing the wiring 240 with a connector in the ceiling before the installation work of the lighting fixture 200, the lighting fixture 200 and the wiring in the ceiling can be electrically connected even if the person is not a qualified electrician. It is possible to perform the work of connecting to the target. Therefore, it is possible for a worker who makes a hole in the ceiling material 300 and installs it as a part of the ceiling to install the lighting fixture 200 as it is.

This means that in the construction of the building 210, the luminaire supplier supplies the luminaire 200 to the ceiling installation worker instead of supplying the luminaire 200 to the electrical material trading company, and the ceiling installation worker performs the ceiling work of the luminaire 200. Is possible.
