2. Description of the Related Art A conventional body of an embedded luminaire is a box-shaped body whose bottom surface is open, and which is mainly made of metal and has reflecting side plates bent diagonally downward on both sides in the width direction. And a pair of end plates attached so as to cover both ends of the main part. A plurality of lamp sockets are attached to the pair of end plates, and the straight tube type fluorescent lamp is supported using the lamp sockets facing each other. A metallic V-shaped reflector located between the adjacent fluorescent lamps is attached to the inner surface of the main part of the instrument body. In this luminaire, the light radiated from the fluorescent lamp toward the inner surface of the main body of the luminaire is formed by the inner surface of the main body of the luminaire, in particular, the reflecting side plate portions on both sides and a V-shaped reflector that is a separate member. It is reflected on the bottom opening. Further, this type of embedded lighting fixture is configured by using the main body of the fixture main body, the end plate, and the like that are separately configured to suit the number of fluorescent lamps that the embedded lighting fixture has.

The V-shaped reflector is preliminarily bent and shaped so that its cross section is substantially V-shaped in a direction orthogonal to its longitudinal direction. Then, these reflectors are fixed to the main body of the appliance by screwing, or the hooking pieces provided on both side edges of the reflector are attached to the back surface of the hooking piece receiving portion provided on the main body of the appliance. It is attached by hooking it through the slit of the receiving portion.

As described above, in the conventional luminaire, it is necessary to bend the reflection plate in advance into a substantially V-shaped cross section, which is costly. Further, the reflection direction in the lighting fixture is largely different between the inclined reflection side plate portion and the V-shaped reflection plate and the horizontal inner surface of the main body of the equipment extending between them, and the horizontal inner surface and the reflection side plate portion are formed. It is difficult to obtain uniform reflection because the reflection is likely to be disturbed at the corners and the corners formed by the horizontal inner surface and the V-shaped reflector.

In addition, an embedded luminaire may be constructed by attaching an attachment to an opening on the lower surface of the luminaire body. As attachments, louvers, baffles,
2. Description of the Related Art There are known attachments for light control such as covers, or attachments for facility equipment in which various equipments such as ventilation holes for air conditioning, speakers, sprinklers are attached. However, since the lower edge of the reflection side plate portion of the luminaire projects outward, the attachment cannot be directly supported by the reflection side plate portion. Therefore, in the conventional embedded luminaire, the attachment cannot be attached unless the attachment attachment component is attached to the lower edge of the reflection side plate portion or the like.

A plurality of, for example, a pair of claws (not shown) connected to the end frame material 2 are provided at both ends of the intermediate connection frame material 4 in the longitudinal direction, respectively. Then, after inserting these claws into the second connecting portion 2b formed of a slit-shaped hole, and twisting the outside of the end frame member 2 respectively,
The end part frame material 2 and the intermediate part connection frame material 4 are connected to each other without requiring special fixing parts. By attaching these intermediate connecting frame members 4, the inside of the instrument body 9 is divided into a plurality of, for example, three frame portions 9a to 9c (see FIG. 1).

Reference numeral 10 in FIGS. 5 and 7B indicates a metal side end connecting frame member. This frame material has an I-shaped cross section consisting of only the vertical plate portion and has the same height as the connecting frame materials 3 and 4. The end frame members 2 are also provided at both ends in the longitudinal direction of the pair of side end connecting frame members 10.
A plurality of, for example, a pair of claws (not shown) connected to the are provided so as to project. Then, after inserting these claws into the third connecting portion 2c formed of a slit-shaped hole, the end frame member 2
The end frame member 2 and the side end connecting frame member 10 are connected to each other by twisting each of them on the outside without requiring a special fixing component. By attaching these side end connecting frame members 10, an air conditioning gap G is formed between the side end connecting frame members 3 and the side connecting frame members 3 facing each other. Intake of room air into the ceiling through this gap G,
Alternatively, the air-conditioning air is blown from the back of the ceiling into the room.

As shown in FIG. 2, the lamp sockets 7 are attached to the first socket attachment portions 2d provided on the frame portions 9a to 9c, respectively. The fluorescent lamp 8 housed in each of the frame portions 9a to 9c is attached with its both ends detachably connected to the lamp socket 7.

The reflecting plate 6 is formed by elastically deforming an elastically deformable rectangular flat plate (see FIG. 1) into an upwardly convex curved shape so that it can be attached to and detached from the respective frame portions 9a to 9c from below. It is arranged. This attachment / detachment is performed with the fluorescent lamp 7 removed.

As shown in FIG. 2, the reflectors 6 arranged on the frame portions 9a and 9c on both sides in the width direction of the instrument body 9 are arranged such that the curved tops 6a of the reflectors 6 are attached to the reflector receiver 5 from below. While abutting, one lower end edge 6b of the reflection plate 6 is placed on a corner formed by the vertical plate portion 3a and the horizontal plate portion 3b of the side connecting frame member 3 to support the top portion 6a and both lower end edges 6b. And is attached to the frame portions 9a and 9c while holding the curved shape.

Similarly, the reflector 6 arranged at the widthwise middle portion of the instrument body 9 has the curved top 6a at the reflector receiver 5a.
And the lower end edges 6b are placed on the corners formed by the vertical plate portions 4a and the horizontal plate portions 4b of the adjacent intermediate connection frame members 4 respectively, so that the top portions 6a and the both lower end edges 6b are And is attached to the frame portion 9b while holding the curved shape.

An ultrafine foamed light reflection sheet can be preferably used for these reflection plates 6. This sheet is made of a PET resin sheet and has a thickness of 1.0 mm, a density of 0.27 g / cm ³ and an average cell diameter of 10 μm or less. And the total reflectance is 555 nm
It has 99.0% and a diffuse reflectance of 96.0% at 555 nm, and further has optical characteristics capable of uniformly reflecting the blue light component and the red light component. Such characteristics are much higher than the diffuse reflectance of a metal reflector having a reflection film of 10% or less, and there is no possibility that the light of the lamp can be reflected only in a specific direction like a metal reflector. It is excellent in that it does not tend to absorb a red color as easily as a metal reflector, and thus the reflected light does not become blue unlike the original color.

Each reflecting plate 6 is attached as described above in such a posture that the direction in which the top portion 6a extends is aligned with the axial direction of the fluorescent lamp 8. These reflectors 6 are arranged so as to cover the fluorescent lamp 8 from the upper side and prevent the upper surface opening of the main body 9 from being visually recognized when the instrument main body 9 is viewed from below.

An insulation-coated electric wire 15 connected to the lamp socket 7 without providing a cutout or the like in the reflection plate 6
The other end notch groove 16 connected to the notch groove 5a is provided in the end frame member 2 so that the end frame member 2 can be routed. Therefore, as shown in FIGS. 3 and 4, the insulation-coated electric wire 15 is routed to the back side of the reflection plate 6 through the cutout groove 16, and as shown by a chain double-dashed line in FIG. It is adapted to be connected to a lighting device 19 such as an electronic ballast, which is attached to the upper part of 3 through a bracket 18.

Further, reference numeral 21 in FIG. 2 denotes a mounting member mounted on the upper portion of the side connecting frame member 3 at a position where it does not interfere with the bracket 18. In addition, reference numeral 22 in FIG. 2 denotes a T-bar supported via a T-bar clip on a C channel arranged on the ceiling of the system ceiling, and 23 denotes a sound absorbing panel forming the ceiling surface of the system ceiling. ing.

Between the T-bars 22 that are adjacent to each other at a predetermined distance, the lighting fixture 1 having the above-described structure places both ends of the lower edge bending portion 2f in the longitudinal direction on the horizontal plate portion of the T-bar 22. By mounting the mounting member 21 on the upper end of the T-bar 22, it is possible to install the T-bar 22 without the need for special fixing or hanging above the ceiling.

Since the multi-light luminaire 1 having the above-mentioned structure uses the ultrafine foamed light reflection sheet for the reflection plate 6, its good reflection characteristics can improve the illumination efficiency and illuminate the lower irradiation field brightly. Further, since the reflector plate 6 made of the above-mentioned reflection sheet is much lighter than the metal reflector plate,
The entire lighting fixture 1 becomes light in weight, and the handling of the lighting fixture 1 during transportation and installation between the T-bars 22 can be facilitated. Moreover, in the present embodiment, the upper surface of the fixture body 1 is still open, and since there is no cover plate that closes this opening, the lighting fixture 1 as a whole can be made even lighter and the number of parts of the fixture body 1 is small. It is possible to reduce the number of assembly steps and costs.

The reflector plate 6 made of the ultra-fine foamed light-reflecting sheet included in the multi-lamp lighting fixture 1 having the above-mentioned structure can be easily elastically deformed. Therefore, the elasticity of the reflection plate 6 is used to move the reflection plate 6 from below the instrument body 9 to each frame portion 9 thereof.
It can be attached to each of a to 9c.

That is, the flat reflecting plate 6 is bent into a curved shape which is convex upward, and while pressing the curved top 6a against the reflecting plate receiver 5 from the lower side, both lower end edges 6b of the curved side or side are formed. Vertical plate portions 3a and 4a of the connecting frame members 3 and 4
By placing it on the corner formed by the horizontal plates 3b and 4b,
Both ends in the longitudinal direction of the top portion 6a and both lower end edges 6b are supported from above and below, and the reflection plate 6 can be attached to the frame portions 9a to 9c while being held in the curved shape by its elastic force.

Therefore, it is not necessary to bend the reflection plate 6 into a predetermined shape in advance, and the reflection plate 6 formed of a rectangular flat plate can be used as described above.
Other than cutting into a rectangular flat plate of a predetermined size, the processing cost for the reflection plate 6 becomes unnecessary. for that reason,
The cost of the reflector 6 can be reduced, and the cost of the lighting fixture 1 can be reduced.

Further, the reflector plate 6 can be attached and detached from the lower side through the lower surface openings of the frame portions 9a to 9c of the instrument body 1 in the reverse order of the above attachment procedure. Therefore, when the reflector 6 is dirty or needs to be replaced, the reflector 6 can be attached and detached from below without removing the entire lighting fixture 1 to clean or reflect the dirty reflector 6. The plate 6 can be replaced.

Further, since the reflecting plate 6 attached to the instrument body 9 by the above procedure is provided while maintaining the upward curved shape as described above, the reflecting surface has sharp corners and creases. Absent. Therefore, a uniform reflection characteristic can be obtained.

Since the luminaire 1 having the above-mentioned structure has portions for mounting both lower end edges 6b of the reflector 6, that is, the horizontal plate portions 3b, 4b of the respective connecting frame members 3, 4, they are used. Then, various attachments can be attached if necessary.

An example thereof is shown in FIG. The exemplified attachment is an attachment U for equipment, to which various equipment such as speakers and sprinklers are attached. The attachment U has a lateral plate portion 4b of the adjacent intermediate connection frame member 4 at both widthwise end portions thereof.
And is mounted over these intermediate connecting frame members 4. In this case, the fluorescent lamp between the adjacent intermediate connecting frame members 4 is removed.

In the case where the light control attachment Q shown by the chain double-dashed line in FIG. 2 is additionally provided, the lateral plate portions of the adjacent connecting frame members are similarly utilized to make the adjacent intermediate connecting frame members 4 It is also possible to attach the attachment Q across the horizontal plate portions 4b or between the horizontal plate portions 3b and 4b of the adjacent side connecting frame member 3 and intermediate connecting frame member 4. In this case, the fluorescent lamp 8 is carried out without being removed.

Then, as described above, the connecting frame member 3,
Since the attachment can be attached by using the horizontal plate portions 3b and 4b of 4, it is not necessary to provide the attachment 1 with a component for attaching the attachment. Therefore, the attachment can be easily attached from below without increasing the number of parts and the number of attachment steps.

When the attachment U for facility equipment is used as the luminaire 1 attached as described above, the frame 9b to which the attachment U is attached cannot illuminate. Therefore, in order to make up for it, FIG. As shown, two fluorescent lamps 8 may be attached to each of the frame portions 9a and 9c. for that reason,
The pair of second socket attachment portions 2e are selected, and the lamp sockets 7 are attached to the end frame members 2 using them, respectively. Therefore, in this case, the lighting fixture 1 for four lights can be configured, and the lack of illuminance due to the use of the attachment U for facility equipment can be eliminated.

In addition, since the lighting fixture 1 having the above-described structure is provided with the third connecting portion 2c on the end frame member 2, the structure shown in FIG.
As shown in (B), the side end connecting frame member 10 can be attached as necessary to form the air-conditioning compatible lighting fixture 1. That is, by mounting the side end connecting frame member 10, an air conditioning gap G for blowing out conditioned air or sucking indoor air can be provided between the side end connecting frame member 10 and the side connecting frame member 3.

As described above, the lighting fixture 1 having the above-mentioned configuration is the lighting fixture 1 for three lights shown in FIG. 2, and the lighting fixture 1 for four lights with the attachment U for facility equipment shown in FIG. 7A.
Or as a lighting fixture 1 for three lights with an air-conditioning gap G. As described above, the lighting device 1 having the above-described configuration can be adapted to changes in several kinds of specifications. Moreover, in response to this specification change, the end frame member 2, each connecting frame member 3,
4 and each reflector 6 can be used in common.

FIG. 8 shows a second embodiment of the present invention. Since this embodiment has basically the same configuration as that of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description of the configuration and operation thereof is omitted. Will be described.

A fluorescent lamp 8 and a lamp socket 7 are provided. Corresponding to this structure, the end frame member 2 is provided with the reflection plate receivers 5 at four locations and the second connection portions 2b at three locations. The configuration other than the points described above is the same as that of the first embodiment including the configuration not shown in FIG.

Therefore, also in the second embodiment, the problems of the present invention described above can be solved by obtaining the same operation as in the first embodiment.

Since this embodiment has basically the same configuration as that of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description of the configuration and operation thereof is omitted. Will be described.

The third embodiment is an example implemented for one lamp. Therefore, the middle connecting frame member is omitted, and the instrument main body 9 that forms one frame part 9e is formed by the pair of end connecting frame members 2 and the pair of side connecting frame members 3.

The light control cover 32 is made of a light diffusion / transmission material or a light reflection material,
The end plate 33 is made of a hard material. And the light control unit 3
1 has a length slightly shorter than the distance between the facing surfaces of the pair of end frame members 2 and is wider than the diameter of the fluorescent lamp 8 and narrower than the lower end opening width of the instrument body 9 (for example, the lower surface). The width is approximately half the opening width).

Since this embodiment has basically the same configuration as that of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description of the configuration and operation thereof is omitted. Will be described.

The fourth embodiment is an example implemented for one lamp. Therefore, the middle connecting frame member is omitted, and the instrument main body 9 that forms one frame part 9e is formed by the pair of end connecting frame members 2 and the pair of side connecting frame members 3. Corresponding to this structure, only one reflector plate 6 is used, only one pair of lamp sockets 7 (only one is shown) are used, and only one fluorescent lamp 8 is used.

Further, in the fourth embodiment, the following configuration is adopted so that the light reflection direction of the reflection plate 6 can be adjusted according to the application. That is, the entire upper edge of the end frame material 2 is bent substantially at a right angle toward the inside of the frame 9e, and the entire upper edge is used as the reflector receiver 5. Further, a slip stopper 13 is sandwiched between the reflection plate receiver 5 and the top portion 6a of the reflection plate 6 positioned so as to be pressed against the lower surface. A rubber plate or the like can be suitably used for the slip stopper 13, and this can be provided on the lower surface of the reflector receiver 5 or the back surface of the top portion 6a, or both surfaces thereof, respectively.

With this structure, the top portion 6a of the reflection plate 6 is formed by using the characteristic that the reflection plate 6 made of the ultrafine foamed light reflection sheet can be easily bent by hand.

It is possible to select either of the usage forms.

Therefore, in the first use mode, illumination can be performed in which the reflection mainly in the downward direction of the instrument main body 9 is increased, whereas in the second use mode, the top portion 6a of the reflection plate 6 is displaced. Accordingly, it is possible to provide illumination in which the reflection of light in an oblique direction is increased. Since the position of the top 6a of the reflector 6 can be arbitrarily selected in this manner, it is possible to adjust the reflection characteristic according to the application. Moreover, the position of the top portion 6a of the reflection plate 6 which is held in a curved shape in an elastically deformed state does not depend only on the elastic force of the reflection plate 6, but can be maintained by the friction resistance with the slip stopper 13. Therefore, the top portion 6 of the reflection plate 6 is displaced from directly above the fluorescent lamp in the width direction of the instrument body 9.
It is possible to prevent a from moving freely due to vibration or the like.

The configuration other than the points described above is shown in FIG.
The configuration is the same as that of the first embodiment including the configuration not shown in FIG.

Therefore, also in the fourth embodiment, the problems of the present invention described above can be solved by obtaining the same operation as in the first embodiment.
