JP-A-2016-31857 (Published March 7, 2016)

As mentioned above, the luminaire has a very elongated shape. Therefore, in the above step (C), when fixing is performed at both ends in the longitudinal direction of the lighting fixture, the center of the lighting fixture hangs down due to its own weight. As a result, there is a problem in that the aesthetic appearance of the luminaire may be impaired and the luminaire may be easily broken due to a heavy load on a specific portion of the luminaire.

The present invention has been made in view of the above problems, and an object thereof is to provide a lighting fixture that achieves a good aesthetic appearance and is not easily broken.

It is a figure of the surface perpendicular|vertical to the longitudinal direction of a lighting fixture which shows roughly the structure of the principal part of the lighting fixture which concerns on Embodiment 3 of this invention.

Modes for carrying out the present invention will be described with reference to FIGS.

[Embodiment 1]
FIG. 1A is a perspective view schematically showing a configuration of a main part of lighting fixture 100 according to Embodiments 1 and 2 of the present invention. 1B is a cross-sectional view taken along the line AA of FIG. 1C is a cross-sectional view taken along the line BB of FIG. Further, FIG. 2 is a perspective view showing a state in which the lighting fixture 100 is disassembled into the mounting member 1 and the lighting body 2. Further, FIG. 3 is a plan view showing a state in which the lighting fixture 100 is disassembled into the mounting member 1 and the illuminating body 2, and is a view schematically showing the configuration of the third fixing member 5 and its vicinity.

In FIG. 1A, the X direction that is the longitudinal direction of the lighting fixture 100, the Y direction that is the lateral direction of the lighting fixture 100, and the Z direction that is the height direction of the lighting fixture 100 are defined. The X direction, the Y direction, and the Z direction are orthogonal to each other. The total length of the lighting fixture 100 in the X direction corresponds to the length of the lighting fixture 100. The entire length of the lighting fixture 100 in the Y direction corresponds to the width of the lighting fixture 100. The overall length of the lighting fixture 100 in the Z direction corresponds to the height of the lighting fixture 100. The luminaire 100 is generally in a very elongated shape, and the length of the luminaire 100 is very large with respect to the width of the luminaire 100.

The lighting fixture 100 includes a mounting member 1, a lighting body 2, a first fixing member 3, a second fixing member 4, and a third fixing member 5. The third fixing member 5 has a permanent magnet 6 and a magnetic material 7.

The mounting member 1 is fixed to the installation surface. The installation surface is a surface facing the mounting surface 8, which is the surface of the mounting member 1 on the side opposite to the illumination body 2, and a specific example thereof is a ceiling or a wall. The illuminating body 2 is connected to the mounting member 1 in the lighting fixture 100, and is removable from the mounting member 1 as shown in FIG. A light source (not shown) for illuminating is usually provided on the illuminating body 2.

In FIG. 1A, a part of the mounting surface 8 is omitted so that the inside of the mounting member 1, particularly the third fixing member 5, can be seen. The same applies to FIG. 4 described later.

Both the longitudinal direction of the mounting member 1 and the longitudinal direction of the illumination body 2 are the same as the X direction. The lateral direction of the mounting member 1 and the lateral direction of the illuminating body 2 are both the same as the Y direction. The height direction of the mounting member 1 and the height direction of the illumination body 2 are the same as the Z direction.

The first fixing member 3 fixes one end of the illuminating body 2 in the longitudinal direction to one end of the mounting member 1 in the longitudinal direction. The first fixing member 3 is formed of, for example, a screw, and firmly fixes the lighting body 2 to the mounting member 1 so that the lighting body 2 does not come off from the mounting member 1.

The second fixing member 4 fixes the other longitudinal end of the illuminating body 2 to the other longitudinal end of the mounting member 1. The second fixing member 4 is formed of, for example, a screw, and firmly fixes the lighting body 2 to the mounting member 1 so that the lighting body 2 does not come off from the mounting member 1.

The third fixing member 5 fixes the center of the illumination body 2 in the longitudinal direction to the center of the mounting member 1 in the longitudinal direction.

The permanent magnet 6 is mounted on a permanent magnet mounting surface 11 that is a surface of the mounting member 1 that faces the illumination body 2. The magnetic material 7 is mounted on the magnetic material mounting surface 12 that is a surface of the lighting body 2 that faces the mounting member 1, and is a plate-shaped member in the lighting fixture 100. Then, the permanent magnet 6 and the magnetic material 7 are magnetically attached to each other, so that the third fixing member 5 fixes the illuminating body 2 to the mounting member 1. In addition, it is preferable to use a permanent magnet having a sufficiently large magnetic force such as a neodymium magnet as the permanent magnet 6 so that the magnetic material 7 does not come off from the permanent magnet 6 due to the weight of the illuminating body 2 during magnetic attachment.

Each of the first fixing member 3 and the second fixing member 4 fixes the illuminating body 2 to the mounting member 1 by screwing. On the other hand, the third fixing member 5 fixes the illuminating body 2 to the mounting member 1 by magnetizing the permanent magnet 6 and the magnetic material 7. Therefore, the fixing strength of the illuminating body 2 to the mounting member 1 by the third fixing member 5 is smaller than the fixing strength of the illuminating body 2 to the mounting member 1 by the first fixing member 3, and the mounting member by the second fixing member 4. 1 is smaller than the fixed intensity of the illuminating body 2.

In the lighting fixture 100, the fixing of the illuminating body 2 to the mounting member 1 by the third fixing member 5 prevents the vicinity of the center of the illuminating body 2 from hanging down due to the weight of the illuminating body 2. As a result, the luminaire 100 having a good appearance can be realized. Further, as a result, it is possible to prevent a large load from being applied to a specific portion of the lighting fixture 100, so that the lighting fixture 100 that is difficult to break can be realized.

Further, since both the permanent magnet 6 and the magnetic material 7 are housed inside the lighting fixture 100, they are not visible from the outside, and from this viewpoint, it is effective for improving the aesthetic appearance of the lighting fixture 100. Therefore, the permanent magnet 6 and the magnetic material 7 do not hinder the illumination.

Further, in the lighting fixture 100, since the fixing strength of the lighting body 2 to the mounting member 1 by the third fixing member 5 is small, there is an advantage that the lighting fixture 100 is not easily broken when the fixing by the third fixing member 5 is released. .. Specifically, when there is fixing by the third fixing member 5, and neither fixing by the first fixing member 3 nor fixing by the second fixing member 4, in the lighting fixture 100, fixing by the third fixing member 5 is easy. Can be canceled. That is, for example, by pulling down either end in the longitudinal direction of the illuminating body 2 in FIG. 1 to a large extent, the fixation by the magnetic attachment at the center can be released, and as a result, the illuminating body 2 can be easily attached from the mounting member 1. Can be removed.

[Embodiment 2]
The fact that the third fixing member 5 has the permanent magnet 6 and the magnetic material 7 has been described in the first embodiment. On the other hand, as shown in FIG. 1A, the third fixing member 5 has a guide member 9 and a permanent magnet fixing member 10 in addition to the permanent magnet 6 and the magnetic material 7. The second embodiment will be described below with reference to FIGS. 3 and 4.

The guide member 9 is a bracket-shaped member mounted on the magnetic material mounting surface 12. The guide member 9 has a hole 13 formed in the magnetic material 7 in a direction perpendicular to the magnetic material mounting surface 12 (that is, in the Z direction). The guide member 9 has a function of guiding the permanent magnet 6 to the magnetic material 7, and the permanent magnet 6 can reach the magnetic material 7 by passing through the hole 13 formed in the guide member 9. it can. The guide member 9 is made of stainless steel. When the guide member 9 is magnetically attached to the permanent magnet 6, it prevents the permanent magnet 6 from reaching the magnetic material 7. In order to prevent magnetic attraction between the guide member 9 and the permanent magnet 6, the guide member 9 is preferably made of a non-magnetic material such as stainless steel.

The permanent magnet fixing member 10 is a bracket-shaped member that fixes the permanent magnet 6 to the permanent magnet mounting surface 11. The outer shape of the permanent magnet fixing member 10 when viewed in the direction perpendicular to the permanent magnet mounting surface 11 (that is, the Z direction) is rectangular.

Here, for example, in the comparative example (see FIG. 4) with respect to the lighting fixture 100, the longitudinal direction of the outer shape of the permanent magnet fixing member 10 substantially coincides with the Y direction, but in this case, the permanent magnet fixing member 10 and the mounting member 1 are arranged. The distance from the end portion 14 in the lateral direction becomes extremely short, or the permanent magnet fixing member 10 and the end portion 14 are in contact with each other. The closer the distance between the permanent magnet fixing member 10 and the end portion 14 is, the easier the magnetic field leaks to the outside of the mounting member 1. When the permanent magnet fixing member 10 and the end portion 14 are in contact with each other, the leakability is the maximum. Become. When the magnetic field leaks to the outside of the mounting member 1, the magnetic field attracts the iron powder, and the dust containing the iron powder adheres to the lighting fixture 100, so that the lighting fixture 100 becomes dirty. Therefore, in order to prevent the lighting fixture 100 from being contaminated with dust, it is preferable that the permanent magnet fixing member 10 and the end portion 14 are separated from each other as much as possible. From this point of view, in the lighting fixture 100, the longitudinal direction of the outer shape of the permanent magnet fixing member 10 is substantially aligned with the X direction, in other words, substantially parallel to the longitudinal direction of the mounting member 1. The length of the mounting member 1 in the longitudinal direction is much larger than the length of the mounting member 1 in the lateral direction. Therefore, the leakage of the magnetic field to the outside of the mounting member 1 due to the distance between the permanent magnet fixing member 10 and the longitudinal end portion 15 of the mounting member 1 can be ignored. The separation distance between the permanent magnet fixing member 10 and the end portion 14 is appropriately set according to the magnetic force generated by the permanent magnet 6 and the magnetic material 7, for example, the short distance between the guide member 9 and the illuminating body 2. It is preferable that the distance is larger than the distance from the end in the direction.

The mounting member 1 (at least the permanent magnet mounting surface 11) is preferably made of a base material of a non-magnetic material such as stainless steel. This reduces the risk of the magnetic field leaking to the outside of the mounting member 1, so that it is possible to prevent the lighting fixture 100 from being contaminated with dust. Further, it is preferable that the member having at least the magnetic material mounting surface 12 of the illuminating body 2 (at least the magnetic material mounting surface 12) is made of a base material of a non-magnetic material such as aluminum. This reduces the risk of the magnetic field leaking to the outside of the illuminating body 2, so that it is possible to prevent the lighting fixture 100 from being contaminated with dust. However, it is not essential that both of them are made of a non-magnetic material base material, and at least one of them may be made of a non-magnetic material base material.

As shown in FIG. 3, the lighting fixture 100 includes a power supply unit 16 that is a power supply circuit of the lighting fixture 100.

Since both the permanent magnet 6 and the magnetic material 7 are housed inside the lighting fixture 100, the influence of the magnetic lines of force on the outside of the lighting fixture 100 and the power supply unit 16 is small.

5A to 5C are perspective views showing an example of an assembling method of the third fixing member 5.

First, in the step shown in FIG. 5A, the permanent magnet fixing member 10 is mounted on the permanent magnet mounting surface 11 of the mounting member 1 in the longitudinal center thereof, and the permanent magnet 6 is fixed to the permanent magnet fixing member 10. To do. The longitudinal direction of the outer shape (rectangular shape) of the permanent magnet fixing member 10 is substantially parallel to the longitudinal direction of the mounting member 1.

Subsequently, in the step shown in FIG. 5B, the magnetic material 7 is mounted on the magnetic material mounting surface 12 of the illuminating body 2 in the longitudinal center thereof. In FIG. 5B, a groove 17 that is opened in the lateral direction of the magnetic material mounting surface 12 is formed at each of both ends in the lateral direction of the magnetic material mounting surface 12. Then, by inserting one end and the other end of the magnetic material 7 into the two grooves 17, the magnetic material 7 is fixed by the two grooves 17. At this time, screw holes 18 and screw holes 19 are formed in the magnetic material 7.

Subsequently, in the step shown in FIG. 5C, the guide member 9 is mounted at the center of the magnetic material mounting surface 12 of the illuminating body 2 in the longitudinal direction. In FIG. 5C, the guide member 9 is provided with a screw hole 20 and a screw hole 21. Then, the guide member 9 is fixed to the magnetic material 7 by the screw 22 penetrating the screw hole 18 and the screw hole 20 and the screw 23 penetrating the screw hole 19 and the screw hole 21. In order to prevent magnetic sticking to the permanent magnet 6, it is preferable that both the screw 22 and the screw 23 are made of stainless steel.

Further, in FIG. 5C, the size of the hole 13 is slightly larger than the size of the outer shape of the permanent magnet 6 (for example, about 1 mm to 2 mm). The guide member 9 is formed adjacent to the hole 13 and has a cut-and-raised portion 24 extending toward the magnetic material 7 by about 3 mm to 5 mm. Since the guide member 9 has the cut-and-raised portion 24, it becomes easy to magnetically attach the permanent magnet 6 to a desired position on the magnetic material 7.

Further, in terms of size, a slight gap is formed between the permanent magnet 6 and the magnetic material 7 which have passed through the hole 13 so that the permanent magnet 6 and the magnetic material 7 contact each other only by magnetic attachment. The positional relationship between the magnet 6 and the magnetic material 7 may be set.

[Embodiment 3]
FIG. 6 is a view of a plane perpendicular to the longitudinal direction of the lighting fixture 200, which schematically shows the configuration of the main part of the lighting fixture 200 according to Embodiment 3 of the present invention.

The lighting fixture 200 is different from the lighting fixture 100 in that the third fixing member 105 is provided instead of the third fixing member 5, and the other configurations are similar to the lighting fixture 100.

The third fixing member 105 includes spring fittings (male) 106 mounted on the surface 111 of the mounting member 1 on the side of the lighting body 2 and spring fittings (female) mounted on the surface 112 of the lighting body 2 on the side of the mounting member 1. It has 107. The spring fitting (male) 106 has a convex portion 108 protruding in the lateral direction of the lighting fixture 200, and the spring fitting (female) 107 has a concave portion 109 recessed in the lateral direction of the lighting fixture 200. ing. The third fixing member 105 fixes the illuminating body 2 to the mounting member 1 by fitting the convex portion 108 into the concave portion 109.

By mounting the spring fitting (male) 106 on the mounting member 1 by spot welding, there is an advantage that the number of holes formed in the mounting member 1 can be reduced in the lighting device 200.
