DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a ceiling mounted on a horizontal member constituting a ceiling frame structure in a suspended ceiling structure.

[0002]

2. Description of the Related Art In recent years, a single-layer ceiling frame has been proposed in place of a conventionally used double-layer ceiling frame composed of a field support and a field edge. A single-layer ceiling frame does not use unnecessary ceiling frame members, which saves materials used, and does not use complex ceiling frame members in the ceiling construction space. When installing piping for building equipment to be installed, it is easy to install without disturbing the ceiling frame members, the number of component parts is small, and in many cases, prefabricated materials are used instead of semi-prefabricated materials. Various advantages can be obtained, such as a reduction in manual work at the site such as an unloading operation and a cutting operation, and ease of construction. In addition to these advantages, there is also a proposal to incorporate the building equipment and devices to be exposed indoors into the horizontal frame itself, which is a ceiling frame member, to further simplify the ceiling structure and facilitate its assembly and construction. Is being done. However, the technology for incorporating building equipment to be exposed indoors into the horizontal members is very small as a result of construction work, the technology has not been established, and the completed ceiling has many problems.

[0003] In the case where lighting equipment among building equipment is incorporated into a horizontal member for a ceiling frame, a fluorescent lamp is built in the internal space of the horizontal member having a substantially inverted U-shaped cross section, and the horizontal member is released. If the louver members are installed from below on both lower edges, it can be considered that the lighting device can be made compact as a basic mode of assembling the lighting equipment. However, simply implementing such a mode causes various problems. Occurs. A major issue is dealing with fever. Fluorescent lamps and associated lighting fixtures generate considerable heat when used. When the lighting equipment is incorporated into the horizontal member, the space in which the lighting equipment is incorporated is formed compactly and closed, so if no measures are taken to dissipate the heat, the heat will accumulate, Lighting equipment and other nearby building equipment become hot and cause equipment failure or damage. It is conceivable to make a hole for air circulation in the horizontal member near the lighting fixture installation location to dissipate heat, but since the horizontal member is a structural material that constitutes the ceiling frame, Drilling in the material will lead to weakening of the ceiling frame. In the case where a lighting device is incorporated in the horizontal member, the advantage of reducing the number of components by using the inner surface of the horizontal member as a reflecting plate of a fluorescent lamp can be expected. It is not advisable to adopt a means of lowering. In this way, perforation of the horizontal member is a means to be avoided as much as possible,
Exothermic treatment should be by other means.

[0004]

The problem to be solved by the present invention is to positively transmit the heat generated by the lighting fixture incorporated in the ceiling frame to the horizontal member, and to reduce the heat generation of the building equipment by the heat. To provide a lighting device on a ceiling that prevents failure, prevents light leakage from a lighting space, has good lighting efficiency, and is easy to install a louver member and can be accommodated in a compact volume. is there.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a ceiling lighting device of the present invention has the following main features. A metal member formed of a shape having a substantially inverted U-shape in cross section, having an inner space opened on the lower side, and having both flat portions parallel to the lower edge formed at least near both lower edges. A transverse member, and a lateral side surface has a shape adapted to a transverse cross section of an internal space of the transverse member, and a bottom plate portion of the transverse member substantially corresponds to the two flat surfaces of the transverse member when installed on the transverse member. A pair of metal partition members attached to form a single space or a space for lighting that divides an internal space in a length direction in a single frame or a horizontal member in which an end portion is jointed with an end portion; ,
A louver piece is disposed in the peripheral edge portion, and both widthwise side edges of the peripheral edge portion are fitted to the bottom plate portions of the pair of partition members. A louver member in which both longitudinal edges of the peripheral portion abut on the both flat surfaces of the horizontal member, and a socket portion for connecting terminals of a compact fluorescent lamp in which all terminals are provided at one end. A lighting device for a ceiling, comprising: a lighting device that is suspended and attached to a horizontal member with the socket portion facing the lighting space.

[0006]

Since the lighting space in which the fluorescent lamp is provided is surrounded by a transverse member and a partition member made of a substantially inverted U-shaped profile, the heat generated from the fluorescent lamp is dissipated downward. Except for the heat, all the heat is transmitted to the horizontal members and the partition members. The metal partition member serves as a heat shield plate for the accommodation room of the adjacent building equipment and is attached to a horizontal member similarly made of metal. Conducted to the side beam. A lighting device attached to the fluorescent lamp is also attached to the horizontal member, and heat other than heat dissipated to the surroundings is transmitted to the horizontal member. And a metal horizontal member that is installed horizontally on the ceiling and has a wide exposed surface,
The heat sink itself acts as a radiator, and the conducted heat is radiated from the surface of the horizontal member into the air behind the ceiling. Therefore, the heat generated from the fluorescent lamp and the accompanying lighting fixtures will be quickly dissipated, causing the lighting fixtures and other building equipment installed adjacent to the lighting space to fail or break due to high temperatures. Does not occur. Further, since the lighting space in which the fluorescent lamp is provided is surrounded by the horizontal member and the partition member, there is no light leakage to the surroundings other than the light projected from the lower louver member for lighting. In addition, it is possible to prevent the ceiling surface from being irregularly formed due to careless light leakage.

[0007] Since the inner surface of the horizontal member is used as it is as a light reflecting plate of the fluorescent lamp, high-efficiency lighting is possible without the necessity of installing a separate reflecting plate, and the number of parts is reduced to reduce the installation cost. And help reduce the overall ceiling weight. Further, since the bottom plate of the partition member serving as a foothold for fitting the louver member to the horizontal member is located near both lower edges of the horizontal member, the fitting operation of the louver member and the fluorescent lamp can be performed. Can be easily performed using the large space below the ceiling surface. Furthermore, since the horizontal member on which the louver member is installed has both flat portions parallel to the lower edge near both lower edge portions of the substantially U-shaped profile, the louver member peripheral edge portion is formed. In this case, both side edges in the length direction come into close contact with both flat surfaces, so that a well-coordinated lighting device can be obtained in a compact space as a whole.

As is clear from FIG. 3, the horizontal member 1 also has a function as a light reflector for the compact fluorescent lamp 9.
That is, the compact fluorescent lamp 9 is surrounded on its top and both sides by the top wall 1a and both side walls 1b of the horizontal member 1, and light from the compact fluorescent lamp 9 upward and on both sides is transmitted to these top fluorescent lamps 9. The light is reflected by the inner surface of the wall 1a and the inner surfaces of the side walls 1b and converted into a lower light beam effective for illumination, thereby enabling highly efficient illumination. In order to enhance this function, the inner surfaces of the top wall 1a and both side walls 1b can be coated with a paint having high light reflection efficiency. Since the horizontal member 1 also has a function as a light reflecting plate, it is not necessary to separately install a reflecting plate, the number of components can be reduced, the installation cost can be reduced, and the entire ceiling structure can be measured. I can do it.

A louver member is provided for partitioning the internal space 2 of the horizontal member 1 to define a lighting space 18 and for providing a foothold for installing the louver member 10 provided below the lighting space 18. A pair of metal partition members 7 are attached to the horizontal member 1 at an interval equal to the length of the partition member 7. In the case of the present embodiment, the pair of partition members 7 are connected to each other so as to divide the lighting space 18 so as to straddle the joint portions of the two lateral members 1 joined to each other by joining the ends. It is attached facing the material 1. As shown in FIG. 5, the partition member 7 has a substantially U-shaped vertical cross section, and is erected to face each other in a state where the front plate portion 7b and the rear plate portion 7c are connected by the bottom plate portion 7a. The width of the front plate portion 7b and the rear plate portion 7c is equal to the distance between the opposite side walls 1b of the horizontal member 1, and the heights of the front plate portion 7b and the rear plate portion 7c are all horizontal. The height is substantially the same as the height of the side wall 1b of the bridge member 1, and the bottom plate portion 7a
Are parallel and flush with both flat surfaces 1g when the partition member 7 is mounted, so that the lateral side surfaces of the front plate portion 7b and the rear plate portion 7c match the cross section of the internal space 2 of the horizontal member 1. Shape.

At both ends in the width direction of the bottom plate portion 7a, a pair of side mounting claw pieces 7i, 7i bent upward are provided. The top of the front plate 7b is at the same height as the top of the rear plate 7c. On the top of the front plate, a front plate mounting claw 7g is provided.
On the top of the rear plate portion, two rear plate mounting claw pieces 7h are formed so as to face outward with their claw tip ends facing each other. Reference numeral 7f is a cutout portion for inserting a socket portion provided on the rear plate portion 7c to allow the socket portion of the lighting device to pass when the lighting device is mounted, and 7d is provided with a louver member 10 described later. For this purpose, a pair of rising pieces 7e are provided in the width direction of the rectangular insertion hole 7d, which are provided at the center of the bottom plate portion 7a. In order to attach the partition member 7 to the horizontal member 1,

(b) A pair of side mounting holes 16 are drilled in the lower end.

In order to attach the partition member 7 to the horizontal member 1, the pair of side mounting claw pieces 7i of the partition member 7 are fitted into the pair of side mounting through holes 16 of the horizontal member 1 while partitioning. The member 7 is inserted into the internal space 2, and on the front plate 7 b side, one front plate attaching claw piece 7 g is engaged with the edge of the front plate attaching notch 14 of the horizontal member 1, and On the side of the rear plate 7c, the two rear plate mounting claw pieces 7h are engaged with the edges of the two rear plate mounting through holes 15. In this way, a pair of partition members 7 are attached to partition one illumination space 18 and to install one louver member 10 described later. As described above, the interior space 2 of the horizontal member 1 is partitioned by the pair of partition members 7 into the illumination space 18 in which the compact fluorescent lamp 9 is disposed. All of the heat generated from the compact fluorescent lamp 9, which is surrounded by the pair of partition members 7, is transmitted to the horizontal member 1 and the pair of partition members 7, except for the heat radiated from the lower release surface. The metal partition member 7 is provided in the inner space 2.
At the same time, serves as a heat shield plate for the accommodation room of other adjacent building equipment and is attached to the transverse member 1 also made of metal, and the heat of the partition member 7 on the high temperature side is low. To the horizontal member 1 on the side. Since the lighting fixture 8 attached to the compact fluorescent lamp 9 is also attached to the horizontal member 1 as described above, heat other than heat radiated to the surroundings is transmitted to the horizontal member 1. The horizontal metal member 1 having a wide exposed surface, which is installed horizontally in the ceiling, serves as a radiator, and the conducted heat is radiated into the air behind the ceiling. Therefore, the heat generated from the compact fluorescent lamp 9 and the lighting equipment 8 associated therewith is quickly radiated, so that the lighting equipment 8 and other building equipment installed adjacent to the lighting space 18 can be used. No failure or breakage due to high temperature occurs.

Since the illumination space 18 in which the compact fluorescent lamp 9 is provided is surrounded by the horizontal member 1 and the pair of partition members 7, it is projected from a lower louver member 10 described later for illumination. Light leakage does not occur in the surroundings other than the light to be illuminated, and the appearance of the ceiling surface due to careless light leakage can be prevented. In this embodiment, the partition member 7 for installing the louver member 10 and most of the socket portion 8b of the lighting device 8 are provided by arranging the partition member 7 and the lighting device 8 as described above. Since the parts will be arranged overlapping at the same position,
These installation volumes occupying the internal space 2 of the horizontal member 1 are reduced, and the space for the building equipment and the like to be deployed in the internal space 2 of the limited horizontal member 1 is relatively expanded. And facilitate its deployment.

Reference numeral 10 denotes a louver member which is detachably attached to the horizontal member 1. The outer periphery of the louver member is formed by a flat rectangular peripheral portion 10a. In this embodiment,
The peripheral portion 10a is formed of a hollow elongated member having a right-angled triangular cross-section in which a slot 10g extends vertically through the upper portion 10d. The upper portion 10d forms a plane through the entire peripheral portion 10a, and the outer portion 10e. Are formed perpendicular to it. The length dimension of the peripheral portion 10a has a length covering the lighting space 18 in the horizontal member 1, but the dimension in the width direction is
As is clear from FIG. 3, each of the horizontal members 1 has a length such that the longitudinal side edges 10b abut on both flat surfaces 1g. Rim 10
A large number of louver pieces 10i are arranged inside the area surrounded by a. A communication hole 10f is formed at the center of the upper portion 10d of the width direction side edges 10c. As described above, since the slot 10g is provided in the upper portion 10d of the peripheral portion 10a, the upper portion 1 of the width side edges 10c is provided.
The slot 10g provided at 0d forms a widthwise hole that is continuous with the communication hole 10f across the communication hole 10f. The groove width of the communication hole 10f is set to allow the neck portion 17c of the elastic member 17 to be described later to pass therethrough, and the groove width of the groove hole 10g is set to overlap the bottom band portion 17a and the folded band portion 17b of the elastic member 17 described later. The dimensions are such that the combined thickness can pass. Outer portions 10e at both side edges 10c in the width direction are provided with communication holes 10f.
A through hole 10h for attaching an elastic member is provided which is substantially the same size as the communication hole 10f.

Reference numeral 17 denotes an elastic member which is mounted on the louver member 10 in advance and is provided for pressing the louver member 10 to the horizontal member 1. The elastic member 17 is formed of an elastic material, and as is apparent from FIG.
The bottom band portion 17a is bent from both ends of the bottom band portion 17a.
And both inner ends of the folded band portions 17b are bent upwardly at a neck portion 17c which is close to and can pass through the communication hole 10f of the louver member 10. In addition, both the expanding bands 1 which are curved in a substantially arc shape centering on the bottom band side so that the front end side becomes an expanding shape.
7d, and two locking pieces 17e bent outwardly and vertically to the ends of the two expanding bands 17d. As described above, the elastic member 17 has a large number of bent portions, and the band length thereof is formed to be considerably long. Therefore, when the louver member 10 described later is installed or lowered, the elastic member 17 has a large length. Even when the two expanding bands 17d are deformed so that the distance between them is close to each other, the amount of deformation of the elastic member 17 per unit band length is small, and the elastic member 17 remains in the elastic region for a long period of time. , And can be used for a long time without any trouble.

In order to attach the elastic member 17 to the louver member 10, as shown in FIG. 6, the bottom band portion 17a and both folded bands 17b of the elastic member 17 are connected to the slot 1 of the louver member 10.
0 g, the neck portion 17c of the elastic member 17 is inserted into the elastic member mounting through hole 10h of the louver member 10, and the two expanding bands 17d of the lying elastic member 17 are rotated and erected to form the neck portion 17c. Is moved to the communication hole 10f by a simple operation. In this way, the elastic members 17 are attached to both the width side edges 10c of the louver member 10. In this state, the elastic member 17 does not come out of the louver member 10. Thus, the louver member 10 of the elastic member 17
Attachment can be reliably performed without using a separate attaching means. In order to press the louver member 10 against the horizontal member 1, as shown in FIG.
The front end sides of the two expanding bands 17d of the elastic member 17 attached to the partition member 7 are inserted into the rectangular insertion holes 7d in the bottom plate portion 7a of the partition member 7 by sandwiching the front ends of both the expanding bands 17d. Stop 17
e is engaged with the tip of both rising pieces 7e. Since the bottom plate portion 7a of the partition member 7 is located near both lower edges of the horizontal member 1, the ends of both the widening band portions 17d of the elastic member 17 are connected to the bottom plate portion 7a.
The work of inserting the rectangular insertion hole 7a into the rectangular insertion hole 7a can be easily performed.

The widthwise side edges 10c of the louver member 10
After the engagement of the elastic members 17 attached to both ends,
When the entire louver member 10 is lifted upward, both of the attached elastic members 17 have an arc-shaped double expanding band portion 17d.
The louver member 10 expands while pushing up the tip of the rising piece 7e by the elastic force to pull up the louver member 10,
The expansion of the louver member 10 is stopped in a state in which the two side edges 10b in the length direction contact the flat surfaces 1g of the horizontal member 1 and the louver member 10 is pressed against the horizontal member 1. The state where the louver member 10 is crimped to the horizontal member 1 is a normal installation state of the louver member 10 in other words. The louver member 10 does not cause the installation of the louver member 10 to loosen or generate a vibration noise due to the looseness of the louver member 10 due to its both longitudinal side edges 10b being in close contact with both flat surfaces of the horizontal member 1. . Note that both vertical walls 1d of the horizontal member 1
Not only serves as a guide for guiding the louver member 10 to a normal position when the louver member 10 is crimped, but also when the louver member 10 is installed, the upper portion 10d at both longitudinal side edges 10b of the louver member 10 is removed. It is concealed in a position that cannot be seen from the inside of the room, and improves the appearance from the inside of the room.

When the louver member 10 is to be pulled down during repair of the lighting equipment including replacement of the fluorescent lamp, if the louver member 10 in the installed state is pulled down as it is, the two expanding bands of the elastic member 17 can be obtained. The portion 17d is lowered while being guided by the leading ends of the upstanding pieces 7e, and can be lowered until the locking pieces 17e abut against the upstanding pieces 7e. In this state, minor work such as replacement of the fluorescent lamp can be performed, and at this time, the louver member 10 can be prevented from being unintentionally dropped. To completely remove the louver member 10,
What is necessary is just to release the locking of the both locking pieces 17e to the both rising pieces 7e. 7 and 8 show a second embodiment of the present invention. The ceiling frame in this embodiment is formed in a lattice shape, and the same horizontal members 31 arranged in a lattice shape.
Is a structure in which four ends are joined at intersections of a lattice and are suspended at the intersections by suspending means.
The lighting spaces 18 in this embodiment are provided independently at positions close to the respective ends of each of the transverse members 1 alone. A pair of partition members 37 are provided opposite to each end of the material 1 alone. Therefore, in the vicinity of the intersection of the horizontal members 1, there are four independent lighting spaces 18 arranged in a cross shape, and a louver member 40 having an elastic member 47 corresponding to each lighting space 18 is provided. It has a configuration to be installed.

The support member 37 of this embodiment is different from the first embodiment in that the width of the front plate portion 37b is smaller than the width of the rear plate portion 37c, and the support member 37 is located near the intersection. When mounted, it is configured to prevent interference with other members, and is not provided with a configuration corresponding to the side mounting claw piece 7i of the first embodiment, but this point is a basic feature of the present invention. This is a matter other than the main part, and other structural shapes and the like are the same as those of the support member 17 of the first embodiment. In this embodiment, the horizontal member 3 for inserting the socket portion 38b of the lighting fixture 38 is used.
Unlike the first embodiment, the socket part insertion through hole 41 in the first embodiment is perforated apart from the mounting position of the partition member 37, but this point is also different from the basic essential part of the present invention. It is a matter.
