Hereinafter, embodiments will be described with reference to the drawings. In the drawings, 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 body 10.
FIG. 3 is a rear view of the lamp body 10 and the fitting adapter 40.

The lamp body 10 includes a base plate 11 and a translucent cover 30. As shown in FIG. 2, the cover 30 has a quadrangular 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 from each other 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 spaced apart from each other in the direction orthogonal to the extending direction and are symmetrically arranged with respect to the fitting adapter 40 provided in the central portion of the base plate 11. A cushion material 18 is provided on the back surface of the base plate 11 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. The side surface of the cover 30 covers the side of the space 70. The base plate 11 is a metal plate, for example, and functions as a reinforcing plate and a heat dissipation 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 arrangement surface 21a and a back surface 21b opposite to the light source arrangement surface 21a. A plurality of light sources 22 are periodically arranged on the light source arrangement surface 21 a 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 an equal pitch.

The substrate 21 is, for example, a resin or ceramic insulating substrate, and a conductor pattern is formed on the light source placement surface 21a thereof. The light source 22 includes 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 21 a of the substrate 21, and the electrode of the light emitting element 23 is 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. A 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. The resin member 25 having such a shape functions as a lens that gives the light source 22 a bat wing type light distribution characteristic.

FIG. 6 is a diagram showing an example of a bat wing type light distribution characteristic. 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 light emitted from the light source 22.

The bat 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 0° to −90° and the emission angle is 0°. The light distribution characteristic has a second intensity peak that is larger than the intensity when the emission angle is 0° in the range of 90° to 90°.

Since the light source 22 has a bat wing type light distribution characteristic, even if the distance between the light source 22 and the cover 30 is short due to the thinning of the lamp body 10, a uniform light emitting surface with less uneven brightness can be obtained. Further, it is possible for a person who has the main surface portion (main light emitting surface) 31 of the cover 30 in the field of view to hardly feel the light source 22 as a dot-like glare.

The cover 30 is transparent to the light emitted by the light source 22. The cover 30 is formed, for example, in a milky white color having a light diffusing property in which titanium oxide or the like is dispersed in a resin material. The cover 30 has flexibility.

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

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 cylindrical portion 51 of the power adapter 50 is formed in a cylindrical shape, and the ceiling member 300 is formed with a circular mounting hole 300a. The cylindrical 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 in 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 contacts the ceiling surface in the vicinity of the mounting hole 300a. The tubular portion 51 extends rearward (upward) from the flange 58, and the power supply unit 52 provided on the tubular portion 51 is arranged in the space on the back side of the ceiling member 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 body 10, the end portion 15 a of the leaf spring 15 in the longitudinal direction is connected to the end portion 33 of the cover 30 so as to be inserted. The end portion 33 of the cover 30 is provided at the tip of the side surface portion 32 folded back from the main surface portion 31.

In a state where the lamp body 10 and the fitting adapter 40 are not attached to the power adapter 50, the end portion 33 of the cover 30 coupled with the end portion 15 a of the leaf spring 15 projects 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. At the tip of each slide member 42, a claw portion 42a having an inclined surface is provided. By 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 the through hole 44 (illustrated in FIG. 12) formed in 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 inside the cylindrical portion 51 of the power adapter 50 fitted in the mounting hole 300a of the ceiling material 300, the lamp body 10 is fixed to the ceiling material 300. Can be attached to.

As shown in FIG. 12, when the case 41 of the fitting adapter 40 is fitted in 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 faces abut. Along with the operation of pushing the fitting adapter 40 further into the tubular portion 51, the two slide members 42 compress the spring 43 by the force received by the claw portion 42a from the inner wall of the fitting hole 61a so that they approach each other. Slide to. The claw portion 42a is retracted to the inside of the case 41 and allows the fitting adapter 40 to be further pushed.

Then, 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 causes the two slide members 42 to separate from each other. Is urged in the direction of doing. The claw portion 42a projects to the outside of the case 41, and the lower surface of the claw portion 42a rides on the upper surface of the fitting member 61 near the fitting hole 61a as shown in FIG. 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, connect the DC (direct current) input connector 45 on the fitting adapter 40 side shown in FIGS. 1 and 3 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 source unit 50. The AC power of the commercial power supply is converted into DC power by the power supply unit 50 and supplied to the light source 22.

When the above-described fitting adapter 40 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 61 a of the power adapter 50. As described above, since the end portion 33 of the cover 30 coupled to the end portion 15a of the leaf spring 15 projects beyond the back surface of the leaf spring 15, 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. 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, by deforming the leaf spring 15 and completely fitting the fitting adapter 40 into the fitting hole 61a of the power supply adapter 50, the restoring force of the deformed leaf spring 15 causes the lamp body 10 to fall on the ceiling. It is 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 the screw 16 as shown in FIG. 10. Deform 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 abuts the ceiling surface, and the portion of the leaf spring 15 on the end 15a side warps downward with the screw 16 as a fulcrum. Therefore, a restoring force for returning to a flat state acts on a 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 by.

When the planar size of the lamp body 10 increases, the end portion of the lamp body 10 is more likely to drop downward due to its own weight, compared to 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 entry of foreign matter into the back side of the lamp body 10 (gap between the ceiling surface).

In the state where the lamp body 10 is attached to the power adapter 50, the cushion material 18 provided on the outer edge portion 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 in the outer edge portion 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, in the state where the lamp body 10 is attached to the power adapter 50 fitted into the ceiling material 300 via the fitting adapter 40, the main surface portion 31 of the cover 30 is substantially flush with the ceiling surface. It becomes parallel and is directed toward the space below the ceiling.

Alternatively, the lamp according to the embodiment can be attached to the wall material by the same method as the above-described 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 larger 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 a region 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 a 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, and the construction material is smaller in size than the lamp body 10 and the power adapter 50 is used. You only need to make one mounting hole for each size. The power supply adapter 50 can be easily attached/detached to/from the mounting hole by 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, it is possible to significantly reduce the number of construction steps for mounting the lamp on the building material.

In addition, since the various types of lamp bodies 10 can be easily attached/detached to/from the power adapter 50 common to them, it is possible to change to another type of lamp body 10 without trouble. When changing the lamp body 10, the common power adapter 50 does not need to be removed 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.

Next, a second embodiment of the present invention will be described.

A metal stay 114 that reinforces the lamp body 110 is provided on the back surface of the metal plate 111. For example, two metal stays 114 extend along one side of the rectangular metal plate 111. The two metal stays 114 are separated from each other in a direction orthogonal to the extending direction thereof and are symmetrically arranged with respect to the fitting adapter 140 provided in the central portion of the metal plate 111. A cushion material 113 is provided on the back surface of the metal plate 111.

The lamp body 110 further includes a light source module 20 and a translucent cover 130. The light source module 20 has the same configuration and characteristics as the light source module 20 of the first embodiment, as shown in FIGS. 4 to 6 and 27. The light source module 20 of the second embodiment is attached to the surface opposite to the back surface of the metal plate 111, and the cover 130 is attached to the metal plate 111 so as to cover the light source module 20. The metal plate 111 functions as a reinforcing plate and a heat dissipation plate of the light source module 20.

Similar to the first embodiment, the light emitting element 23 of the light source module 20 is mounted on the light source arrangement surface 21 a 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 conductor pattern formed on the board 21 is electrically connected to the lamp-side connector 143 provided on the upper surface of the fitting adapter 140 of the second embodiment.

The cover 30 is transparent to the light emitted by the light source 22. The cover 30 is formed, for example, in a milky white color having a light diffusing property in which titanium oxide or the like is dispersed in a resin material. The cover 30 has flexibility.

As shown in FIG. 18, the cover 130 has a main surface portion 131 and a side surface portion 132. The main surface portion 131 faces the light source 22 with a space 170 in between. The side surface portion 132 is provided continuously to the end portion of the main surface portion 131 and covers the side of the space 170.

The lamp body 110 has a plurality of convex portions 181. The convex portion 181 projects from the light source arrangement surface 21 a toward the main surface portion 131 of the cover 130, and is arranged in the space 170 with a gap from the main surface portion 131.

The height of the convex portion 181 from the light source arrangement surface 21a is larger than the height of the light source 22 from the light source arrangement surface 21a.

As shown in FIG. 27, the plurality of convex portions 181 have at least two convex portions 181 that are located in the plane direction of the light source arrangement surface 21a with the arrangement location (represented by a broken line) of the fitting adapter 140 interposed therebetween. In the example shown in FIG. 27, four convex portions 181 are provided around the location where the fitting adapter 140 is arranged.

The distances between the convex portions 181 adjacent to each other along the side of the light source arrangement surface 21a are equal. The distance between the center of the fitting adapter 140 and each of the protrusions 181 is equal. The distance between the center of the fitting adapter 140 and each convex portion 181 is shorter than the distance between the corner of the light source placement surface 21a and each convex portion 181. The distance between the center of the fitting adapter 140 and each convex portion 181 is shorter than the shortest distance between the side of the light source placement surface 21a and each convex portion 181.

The convex portion 181 is made of a translucent material and is, for example, milky white or translucent. The convex portion 181 is made of, for example, a resin material. Further, the convex portion 181 does not contact the main surface portion 131 of the cover 130. Therefore, the protrusion 181 does not become a shadow for a person who views the cover 130 from the outside. The convex portion 181 does not affect the light emission characteristics.

The lamp 100 of the second embodiment is attached to the ceiling material 300 by the mounting bracket 160. FIG. 19 is a perspective view of the mounting bracket 160.

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 not overlapping the mounting hole 300a on the back side of the ceiling material 300.

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 connectable 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 151 a is provided at an end of the electric cable 151.

In a state before the lamp body 110 is mounted on 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 into the mounting hole 300a, and the power source The side connector 151a is located on the front side of the ceiling material 300.

An operator who performs the mounting work of the lamp 100 brings the lamp 100 close to the ceiling material 300, holds the lamp 100 with one hand, and uses the other hand to connect the power supply side connector 151a of the electric cable 151 hanging from the mounting hole 300a. The power supply side connector 151a is connected 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 by grasping.

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 fitting 160 fitted into the fitting hole 300a of the ceiling member 300.

FIG. 22 is a perspective view showing a fitting structure of the fitting 160 and the fitting adapter 140.
FIG. 23 is a cross-sectional perspective view showing a fitting structure between 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 connecting the two slide members 145.

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

22 and 23 show a state in which the claw portion 144 projects 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, a stopper 141a projecting downward from the upper case 141 is located in a recess 146 formed on the upper surface of the slide member 145, and the stopper 141a and the wall surface of the recess 146 come into contact with each other to make two slides. The movement of the members 145 in the direction away from each other is restricted.

Usually, the claw portion 144 projects to the outside of the cases 141, 142. When the fitting adapter 140 is fitted into 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 two slide members 145 compress the spring 147 by 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, and slidely move toward each other. The claw portion 144 is retracted inside the cases 141 and 142, and allows 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 that the claw portion 144 receives 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. Is biased in the direction. The claw part 144 projects to the outside of the cases 141, 142, and the lower surface of the claw part 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.

When 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 by a method similar to the method of attaching 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 larger than the area of the mounting hole 300a of the ceiling member 300 and the area of the opening 164 of the mounting bracket 160, and the light source is also disposed in the area of the lamp body 110 overlapping the fitting adapter 140. 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 a light emitting surface can be obtained over a wide area.

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

The worker fits the fitting adapter 140 into the mounting bracket 160 while manually pushing up the central portion (placement of the fitting adapter 140) 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 is bent so as to be recessed toward the fitting adapter 140 side, and the back surface 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, and 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, it is possible to apply a load to the fitting adapter 140 evenly and easily. 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 serves as a stopper to restrict 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 location where the fitting adapter 40 is arranged. 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 contacts 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, and the fitting adapter 40 can be fitted into the power supply adapter 50. Further, the convex portion 181 can prevent the cover 30 and the light source 22 from being damaged due to collision.

Next, a method for 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 removing member 112 is exposed on the side surface of the lamp body 110, and an operator can grasp the one end 112c of the removing member 112 with a finger or a jig in a state where the lamp body 110 is attached to the ceiling material 300. .. The other end of the detaching member 112 is connected to the slide member 145 of the fitting adapter 140.

25 and 26 are perspective views showing a connection structure between 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 connecting structure of the removing member 112 and the slide member 145 seen from the back side with the lower case 142 removed in FIG. 25.

The detaching member 112 and the slide member 145 are connected via two arm members 148. Each arm member 148 can rotate about a 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 detaching 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. An operator can slide the removing member 112 along the longitudinal direction of the removing member 112 by pulling the one end 112c of the removing member 112 with a jig, for example. 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 one end 112c of the removing member 112 pulls the removing member 112 in a direction protruding from the lamp body 110, the pair of arm members 148 engaged with the pins 112a of the removing member 112 rotate about the shaft portion 142a as a fulcrum. By this 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 directions toward each other.

By this sliding movement of the slide member 145, the state in which the claw portion 144 has been 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 fixed 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 the one end 112c of the removing member 112 is aligned with the notch formed in 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 a color that is the same as or close to the color of the cover 130 (for example, milky white). The removal member 112 is painted white, for example. For this reason, especially at the time of non-lighting, the one end 112c of the removal member 112 is not conspicuous on the side surface of the lamp body 110, and the appearance quality is not deteriorated.

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

According to 2nd Embodiment demonstrated above, it is not necessary to make the square hole according to the shape and size of the lamp main body 110 in a building material, and the construction to the ceiling material 300 is smaller than the size of the lamp main body 110, and it fits. It suffices to drill one mounting hole 300a that matches the size of the mating adapter 140. Then, by fitting the fitting adapter 140 into the fitting 160 fitted in the fitting hole 300a, the lamp body 110 can be easily attached to the ceiling member 300.

The lamp-side connector 143 is fixed to the upper surface of the fitting adapter 140, not connected to one end of the cable and hanging around. On the other hand, the power supply side connector 151 a 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 operator's side 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 operator grasps the power supply side connector 151a with one hand and It is possible to connect the power supply side connector 151a to the lamp side connector 143 while supporting the lamp 100 with one hand attached to the main surface portion 31 of the cover 30 of the lamp 100. The lamp side connector 143 itself does not have to be grasped by hand. Therefore, even if the planar size of the lamp body 110 is increased, one operator can easily electrically connect the power supply unit 150 and the lamp 100 and attach the lamp 100 to the ceiling material 300.

Even when the lamp 100 is removed from the ceiling material 300, one hand is attached to the main surface portion 31 of the lamp 100 to support the lamp 100, and one end of the detachable member 112 described above is used by the other hand by 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 where the lamp 100 is supported by one hand, the other hand can be moved from the detaching member 112 to the power supply side connector 151a and the power supply side connector 151a can be pulled and pulled out from the lamp side connector 143. That is, it is possible for one operator to easily remove the lamp 100 from the ceiling material 300 and release the electrical connection between the power supply unit 150 and the lamp 100.

According to the second embodiment as described above, it is possible to easily connect the various types of lamp main bodies 110 to the power supply unit 150 common to them with one touch, so that it is possible to connect to other types of lamp main bodies 110 without 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 member 160 is formed in an annular shape, and the upper part thereof is open without being closed. Therefore, after the power supply side connector 151a is connected to the lamp side connector 143, when the fitting adapter 140 is fitted into the mounting bracket 160, the electric cable 151 is not pinched or caught anywhere, and the mounting bracket is not caught. Since it can be retracted into the space above 160, the work of fitting the fitting adapter 40 into the fitting 160 is not hindered.

Next, as a third embodiment, when constructing a building such as an office building, a factory, or a commercial facility, the lamp described in the first embodiment, the lamp 100 described in the second embodiment, or the like. The process of installing the [illumination lamp] will be described. Therefore, first, a conventional process in the construction of such a building will be described. FIG. 28 is a flowchart for explaining the flow of lighting installation in the process until the conventional building is constructed. Here, a building having a structure of a plurality of floors, such as a general office building, having passages and living rooms is targeted. In the construction of a large-scale building such as an office building, a general contractor undertakes an order for construction work, and organizes the entire construction work performed by various contractors.

First, a architect or designer designs a building (step S1). In this process, the layout of aisles and living rooms is decided, and the overall design of the building is written on the design drawing. In addition, the building materials to be adopted and electrical equipment materials such as lighting fixtures are also decided to some extent, and their arrangement is also described in the drawing.

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

Next, skeleton construction is performed to form the skeleton of the building on the stable ground (step S3). As for the skeleton work, if it has a foundation part or a basement floor, it will start from the underground construction such as the basement floor and proceed to the ground floor. Placing concrete, installing pillars, and assembling steel frames will complete the framework of the entire building. In addition, concrete will be placed on outer walls, rooftops, floors on each floor, etc.

Also, in the frame work, inserts are embedded in order to lower the suspension bolt in the later interior work. For example, a ceiling insert for fixing suspension bolts is fixed as a part of a slab when placing a floor slab on the upper floor (such as a reinforced concrete floor plate). Here, the workers of civil engineering works and the workers of jump, earthwork, and concrete works mainly perform the work. Next, the exterior work of the building is performed (step S4). Tiling on the outer wall, window sashes, window glass, curtain walls, etc. can be installed. In addition, painting is also performed.

Next, interior work is performed (step S5). In the interior work, the ceiling, walls, and floor are created. In the ceiling work for installing the ceiling, the hanging bolts are lowered from the ceiling insert provided in the frame work of step S3, and the ceiling surface such as the ceiling board or the ceiling underlay material is formed on the underlayer in which the lightweight steel aggregate is combined. Ceiling material is attached. For supporting the ceiling material, hanging materials such as hanging bolts and hangers, and diagonal members are used, and thus, a risk prevention measure such as falling of the ceiling board is taken.

For example, in Japan, the Building Standards Act and the enforcement order provide regulations to prevent such falling of the ceiling. As one of them, it is stipulated that when a ceiling material satisfying a predetermined condition is provided, a fall prevention measure such as fixing with a hanging material is taken. Depending on the size and weight of the lighting fixture, there are those that can be installed on the ceiling without being fixed to the hanging material, and those that are fixed by the hanging material.

Note that the ceiling insert for fixing the suspension bolts can be fixed by anchoring anchors on the concrete after placing, instead of installing it at the time of placing concrete. However, in consideration of efficiency and safety, it is preferable to install it in advance.For places where it is known that suspending materials will be installed, the placement of the ceiling insert is decided at the design stage, and concrete pouring is done. It is desirable to be embedded at the time of.

Further, in the interior work, before the ceiling is stretched, that is, before the ceiling is completely formed by the ceiling material, the piping and the air-conditioning duct are suspended, and the work of passing the electric wire through the piping is also performed. Therefore, a space necessary for installing electric wiring, ducts, air conditioners, etc. is provided in the ceiling. Furthermore, an opening is provided in the ceiling material in accordance with the place where lighting and air conditioning are installed. Here, the work such as the installation of the duct in the ceiling and the fixing of the ceiling material by the suspending material is performed by the worker of the contractor who performs the interior work. On the other hand, the work of installing the electric wiring is performed by a specialized worker who can perform the electric work because there is a risk of electric shock.

In many cases, it is assumed that the ceiling installation worker who installs the ceiling and the wiring installation worker who runs the electrical wiring behind the ceiling are different people. In Japan, electrical work such as wiring work by persons who are not qualified as an electrician is not permitted. As described above, in the construction of a building, workers are dispatched from various specialized contractors, and each of them carries out specialized work, so that safety is taken into consideration.

In the present specification, a worker of a contractor who prepares a ceiling material for building a building and performs ceiling work is called a ceiling installation worker. In addition, a worker of a contractor who prepares electric wiring for the construction of a building and performs wiring work is called a wiring work worker. In addition, the construction of each process in the construction of a building is usually performed 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 work in building construction. The same applies to wiring workers.

Next, when the interior work is completed and the floor, walls, and ceiling are completed, installation work is performed (step S6). In the installation work, the equipment necessary for actually using the building is installed. For example, facilities for electricity, gas, water, water, drainage, air conditioning, toilets, disaster prevention, broadcasting, etc., and facilities such as lighting, escalators, elevators, etc. are arranged. These works are carried out by workers of businesses such as electric work, telecommunication 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, and therefore work by a qualified electrician is required. The location where the lighting is installed is not limited to the ceiling, but the lighting fixtures installed on the ceiling are normally connected to the wiring prepared behind the ceiling by a qualified electrician and electrically connected. To be done. Even when installing an air conditioner on the ceiling in the air conditioning facility work, it is connected to the wiring prepared behind the ceiling by a qualified electrician.

Usually, in a living room of a building such as an office building, large illuminating lamps and air conditioners arranged on the ceiling are fixed by hanging materials. Therefore, the worker who installs such large-sized lighting fixtures and air-conditioning equipment should also fix the large-sized lighting fixtures and air-conditioning equipment to the hanging material hung from the ceiling insert and install them on the ceiling. become.

The luminaire manufacturer manufactures the luminaire necessary for the construction so as to be ready for the lighting installation work, and delivers the luminaire to the electronic material trading company that manages the electrical equipment materials (step S7). Also, electrical material trading companies manage inventory of materials such as switches, outlets, wires, cables, switchboards, antennas, distribution boards, intercoms, fire alarms, etc. The necessary electric equipment materials are supplied in the required amount (step S8). In the present specification, an employee of a supplier who manufactures an illumination lamp or delivers the illumination lamp is called an illumination lamp supplier.

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

In the present specification, when referring to an installation worker, it means one or more workers who perform installation work such as lighting and air conditioning, and the same person as described above refers to the installation work of lighting and air conditioning. It may be included when performing. On the other hand, when referring to a worker who installs lighting, it means one or more workers who install lighting, and who does not install air conditioning. When referring to an air-conditioning installation worker, it means one or more workers who perform air-conditioning installation work, and those who do not perform lighting installation work.

Next, as a third embodiment, a process of constructing a building and a process of installing the lighting fixture 200 in this construction will be described. As the illumination lamp 200 here, the lamp described in the first embodiment or the lamp 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. Note that it may be a one-story building. FIG. 29 is a schematic diagram 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 by the floor 220, the wall 221, the ceiling 222, and the window 223. Note that the room may have no window 223 and only the side wall 221 on the side surface. In addition, a plurality of lighting fixtures 200 and a plurality of air conditioners 230 are installed on the ceiling. The air conditioner 230 may be one.

Here, there are some types of ceiling installation equipment such as lighting fixtures and air conditioners that are installed on the ceiling that need to be directly fixed by suspending materials, and some do not. For example, small ceiling installation equipment such as surveillance cameras, downlights, emergency lighting, or smoke sensor sensors are installed without being fixed by being directly connected to hanging materials such as hanging bolts or diagonal members. It Since such a small ceiling installation tool has a small load applied to the ceiling material, it is recognized that it can be installed without a hanging material. Hereinafter, such a ceiling installation tool is referred to as a ceiling installation tool that does not need to be fixed with a suspending member.

On the other hand, the ceiling-mounted base lighting, the ceiling-embedded base lighting, the air conditioner 230, and the like are fixed and installed by being directly connected to the hanging material. Since such a ceiling-mounted fixture has a large load applied to the ceiling material, unless it is fixed with a suspending material, the risk of falling off is increased when an earthquake occurs, for example. Therefore, the ceiling installation equipment itself is supported by the hanging material, instead of the installation structure in which the entire load is applied to the ceiling material. Hereinafter, such a ceiling installation tool is referred to as a ceiling installation tool that needs to be fixed with a suspending member.

For example, in the case of a building such as an office building, a small ceiling installation fixture such as a downlight is provided for lighting in a narrow space such as a passage, and a large lighting fixture such as a base lighting is provided in a wide space such as a living room. It is possible that Although a small illuminating lamp may be provided in a part of the living room, the majority of the illuminating lamps installed in the entire living room are large-sized illuminating lamps.

The lighting fixture 200 according to the present embodiment has a performance equivalent to that of base lighting as 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. it can. That is, the illuminating lamp 200 is a large-sized lightweight illuminating lamp that is large enough to be handled as equivalent to base lighting but is light enough to require no hanging material.

Here, the lightweight large illuminating lamp in this specification means that the total luminous flux is 2500 lm or more, the area of the light emitting surface which is the surface closest to the floor is 45000 mm ² or more, or 100 or more light source elements are arranged. Lighting fixtures that meet at least one of the following: Alternatively or additionally, the characteristics of the lightweight large lighting fixture may be further specified by the condition that the weight is 0.5 kg or more and less than 2.5 kg.

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

Since the lighting fixture 200 does not need to be fixed by the suspension member 270, the designer or designer need not determine the placement position of the suspension member in step S1 in accordance with the installation position of the illumination fixture 200. In addition, when the ceiling insert is provided and the arrangement position of the suspending member 270 is determined and then the arrangement position of the base lighting that needs to be fixed by the conventional suspending member is changed, it is necessary to newly install a suspending bolt. In the case of the lighting fixture 200, this is not necessary. Therefore, the architect or 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, ceiling work for providing a ceiling is performed. Also, before or after the ceiling is stretched, the wiring arranged behind the ceiling is passed to a position higher than the ceiling. FIG. 30 shows an example of the ceiling above the ceiling when the ceiling construction is performed.

As shown in FIG. 30, the underside of the ceiling has a space in which the upper surface and the side surface are formed by a 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 material 300 forming the ceiling 222 is fixed and supported by a suspending material 270 connected to the ceiling insert of the body 224. Note that the hanging member 270 is partially omitted in FIG. 30 because the drawing becomes complicated. In the space above the ceiling, there are a wiring 240 and a wiring 241 provided through a pipe. This wiring is provided according to the number of electrically connected devices installed in the ceiling such as lighting and air conditioning based on the design drawings. The ceiling 222 is provided after a sufficient number of wirings are prepared for supplying power to the electrically connected equipment.

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

If an electric shock preventive connecting device such as a connector is provided, the work of connecting the wiring 240 to the lighting fixture 200 can be performed even by a person who is not a qualified electrician. In the example of FIG. 30, a connector is provided for the wiring 240 scheduled to be connected to the lighting fixture 200, but no electric shock preventing connection device such as a connector is provided for the wiring 241 scheduled to be connected to the air conditioner 230. .. Therefore, in compliance with Japanese law at the time of application, the work of connecting the wiring 241 to the air conditioner 230 needs to be performed by a person who is qualified as an electrician. Note that the wiring 240 is partially omitted in FIG. 30 because the drawing becomes complicated.

As described above, in the work of providing the wiring arranged behind the ceiling, among the plurality of wiring arranged under the ceiling, the wiring is electrically connected to the illuminating lamp 200 that is not fixed by the suspending member at the time of installation on the ceiling. As the wiring for this, the work of providing the wiring 240 with an electric shock preventive connecting device such as a connector is performed.

Further, since the air conditioning equipment 230 is fixed by the hanging material, a hanging material 271 is provided as a hanging material for fixing the air conditioning equipment 230. At the time of FIG. 30, since the air conditioning equipment 230 is not yet attached, the suspenders 271 do not fix the air conditioning equipment 230.

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

As shown in FIG. 30, the mounting hole 300 a provided to install 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 lighting, in contrast, have openings comparable in size to their luminaires. In the lighting fixture 200, the mounting hole 300a can be 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 in a circular shape having a diameter of 10 cm to 15 cm, for example. The shape of the mounting hole 300a does not have to be circular, and may be polygonal with 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. In order to mount the lighting fixture 200, it is preferable that the mounting hole 300a be large enough for the worker's arm to pass through so that the wiring 240 can be picked up from the room side.

The ceiling material 300 does not have to be provided with an opening in advance. It is a general practice to prepare a ceiling material 300 with no opening and have a worker make a hole in the ceiling material 300 to provide an opening at a site where interior work is performed. It is sufficient to perform the work of appropriately providing the opening for the ceiling material 300 having no opening. The shape of the opening to be prepared may differ depending on what kind of ceiling-installed equipment is installed. Therefore, the opening may be provided when the ceiling material 300 is fixed to the ceiling material 270 and attached to the ceiling, or may be provided after the ceiling is formed.

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

At the time when the ceiling 222 is provided on the building 210, the living room space that is the space forming the living room shown in FIG. 29 and the back ceiling space that is the space forming the back ceiling shown in FIG. It can be treated as a distinct space. Here, the presence or absence of an opening 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, a space having the ceiling 222 as a part of forming a space and a space above the ceiling 222 is a ceiling. A back space, a space having a ceiling 222 as a part of forming the space and a space below the ceiling 222 is distinguished as a living room space.

First, the illuminating lamp 200 and the 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 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 power from the DC power source from the power adapter 250. For example, a DC voltage of 100V is supplied. A worker who is not qualified as an electrician can also perform connection with the DC harness 280. The fitting adapters 40 and 140 correspond to one form of the mounting adapter 211. The power adapter 50 corresponds to one form of the power adapter 250. 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 connecting portion for electrically connecting to the wiring 240 with a connector via the connector. A worker existing in the living space puts his/her arm in the opening, pulls the connector-equipped wiring 240 provided in the space above the ceiling from the opening, and pulls it into the living 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 connecting 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 base 262. The dimming terminal block 262 is not necessary when using the lighting fixture 200 that does not have the dimming function.

In this way, the wiring 240 with a connector and the power adapter 250, which are arranged in the space above the ceiling 222 formed above the ceiling material 300 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, an operation 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 installs the power adapter 250 on the ceiling material 300 by the fastener 290. The fastener 290 has a spring property (elasticity), and is penetrated through the opening of the ceiling material 300 from the ceiling surface side (living room space side). After the penetration, the fasteners 290 are applied to the ceiling back surface of the ceiling material 300, and thus the load is applied to the ceiling material 300. When the illuminating lamp 200 is attached to the ceiling 222, the loads of the one illuminating lamp 200 and the one power supply adapter 250 are applied to the one ceiling member 300. The attachment 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 any structure as long as a load is applied to the ceiling material 300.

Either of the work of connecting the wiring 240 with a connector and the power supply adapter 250 and the work of connecting the power supply adapter 250 and the lighting fixture 200 may be performed first. 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 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 illumination lamp 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 supply adapter 251.

In this case, a worker existing in the living space puts his or her arm through the opening, pulls the connector-equipped wiring 240 provided in the space above the ceiling from the opening, and pulls it into the living 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 space. The terminal block 152 or 153 corresponds to one form of the AC terminal block.

Then, the worker existing in the living space arranges the power supply adapter 251 connected to the connector-equipped wiring 240 on the ceiling above the opening through which the connector-equipped wiring 240 is connected. The wiring 240 with a connector also returns to the back of the ceiling, and the DC harness 281 of the power adapter 251 pops out into the living room space from the opening. The lighting fixture 200 is connected to the DC harness 281 and supplied with power. The electric cable 151 corresponds to one form of the DC harness 281. In addition, 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 back 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 connector-equipped wiring 240 through the opening of the ceiling material 300. Alternatively, the work of installing the lighting fixture 200 on the ceiling member 300 by passing the fastener 291 of the lighting fixture 200 electrically connected to the wiring with connector 240 through the opening of the ceiling member 300 is performed.

Further, the wiring 240 with a connector and the power supply adapter 251 are connected by the connector of the wiring 240 with a connector, and the work of arranging the power supply adapter 251 electrically connected with the wiring 240 with a connector in the space above 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 the attachment fitting 160 having the attachment spring 163 as a fastener. In this case, after the power adapter 251 electrically connected to the connector-equipped wiring 240 is placed in the space above the ceiling, the mounting bracket 160 is installed on the ceiling material 300 by a fastener.

Further, the DC harness 281 of the power supply adapter 251 arranged in the space above the ceiling is drawn 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. The lighting fixture 200 is electrically connected. Further, the lighting fixture 200 is electrically connected to the connector-equipped wiring 240 by being electrically connected to the power adapter 251.

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 installing 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 fixture 160, and the installation work of the lighting fixture 200 on the ceiling member 300 via the mounting fixture 160 is performed. It can be said that the mounting bracket 160 is one form of a mounting auxiliary member that assists the installation of the lighting fixture 200 on the ceiling material 300. The attachment assisting member may have, for example, the same shape and structure as the attachment fitting 160, and may be made of a material other than metal.

The power adapter 251 is arranged in the vicinity of the opening through which the power adapter 251 is located, behind the ceiling material 300 having the opening. Therefore, when the one lighting device 200 is attached to the one ceiling material 300, the one power adapter 251 connected to the lighting device 200 is arranged on the one ceiling material 300. Therefore, as in the first embodiment, the load of the one power adapter 251 and the one illumination lamp 200 is applied to the one ceiling member 300.

The power adapter 251 may be arranged on the ceiling material 300 to which the lighting fixture 200 is not attached. In the example of FIG. 33, the power supply 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 one ceiling member 300 can be reduced. For example, a total of two power supply adapters 251 respectively arranged on two ceiling members 300 in FIG. 33 may be arranged on one ceiling member having no opening. However, if the distance to the ceiling material 300 is too long to reach even with the arm 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 suspending member 270, it is sufficient to provide an opening for pulling out the wiring 240 with a connector on the back of the ceiling to the living room space. In other words, in order to perform the work of installing the lighting fixture 200 on the ceiling 222, it is only necessary to have an opening large enough for the arm to pass through. On the other hand, in the case of an illumination lamp that needs to be fixed with the hanging member 270, it is difficult to attach the illumination lamp from the living room space side by using only the opening large enough for the arm to pass through.

In addition, 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. Can be connected to each other. Therefore, a worker who makes a hole in the ceiling material 300 and installs it as a part of the ceiling can also perform the installation work of the illumination lamp 200 as it is.

In other words, in the construction of the building 210, the lighting fixture supplier supplies the lighting fixture 200 to the electric material trading company instead of supplying it to the ceiling installation worker, and the ceiling installation worker performs the ceiling construction of the lighting fixture 200. It means that you can.
