  The fluorescent lamp of the GX53 base is a new type of fluorescent lamp with a thin and compact design. For example, when used in a downlight or the like, the luminaire main body is embedded in the ceiling, and is designed to be flat with the ceiling surface when the lamp is mounted. Moreover, when it is adopted below the hanging shelf of the system kitchen, it is desirable that the height of embedding is as small as possible, but it is necessary to secure the height of the lighting fixture body.

  The above-mentioned patent documents describe a technique for changing the orientation of the surface to which the power supply is connected or moving the terminal block itself in order to protect the terminal block provided in the embedded lighting fixture from heat and dust. Yes.

  Further, as a method for protecting a power supply line or the like to be inserted into a terminal block from heat, as shown in FIG. 6 (a), a technique of providing a terminal block outside a lighting fixture body using a terminal block mounting plate is known. ing. However, in practice, as shown in FIG. 6B, the terminal block protruding from the luminaire body to the outside must be directed to the embedding location, and the luminaire body must be inserted obliquely. It is necessary to round a part, or to provide a large gap between the embedding place and the lighting fixture, which causes a limitation of shape and a problem of appearance.

  The terminal block is an indispensable component, but in a thin luminaire, it cannot be provided inside the luminaire main body, but directly on the surface of the luminaire main body facing the place where the luminaire main body is embedded. Often fixed. Even if a thin fluorescent lamp with a GX53 cap is used, if the terminal block is provided on the surface facing the place where the lighting fixture body is embedded, the overall height of the lighting fixture will be high, and depending on the location where the height is low There was something I couldn't do.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an embedded lighting fixture that can be attached even in a place where the embedded height is small.

To achieve the above object, an embedded lighting fixture according to a first aspect of the present invention provides:
A lighting fixture body used in an embedded type;
A terminal block for connecting a power line for supplying power to the luminaire body;
One end is supported by the lighting fixture body, and the terminal block is provided at the other end protruding to the outside of the lighting fixture body, and the terminal block is held movably around a portion supported by the lighting fixture. A terminal block holder to

  In the embodiment, the case where the embedded lighting fixture is a fluorescent lamp of a GX53 base will be described as an example. Depending on the type of the light source, the height of the luminaire is higher than the height at which the light source is embedded, so there is a risk that the light fixture must be externally attached without being embedded, or may be overheated. The fluorescent lamp of the GX53 base can solve these problems and can be used as a thin embedded lighting apparatus that can be used in places with a small embedded height, and the effect of the present invention can be expected more.

(Embodiment)
FIG. 1 is a plan view of an embedded lighting fixture using a fluorescent lamp with a GX53 base according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the embedded luminaire according to the embodiment, and represents a cross section taken along line MM in FIG. FIG. 3 is a schematic configuration diagram of an embedded lighting fixture according to the embodiment. The case where the embedded lighting fixture before mounting | wearing in an implantation place is seen from the side is shown briefly. FIG. 4 is a schematic perspective view showing the terminal block according to the embodiment.

  First, the embedding location will be described. A surface to which the lighting fixture is attached is a mounting surface B, and a portion in which the lighting fixture 100 is embedded in the mounting surface B is a buried hole C. The embedded hole C is provided in accordance with the size of the fixture body 1 of the lighting fixture 100. A surface facing the bottom surface portion of the embedded lighting fixture 100 is defined as an inner surface U.

  When the luminaire 100 is embedded in the embedding hole C, that is, in the state of being attached to the attachment surface B, the space surrounded by the bottom surface and the inner surface U of the luminaire 100 is the space S1 and the luminaire 100 in the space S1. The size of the gap in the closest part of the inner surface U is defined as a height H1. A space surrounded by the attachment surface B and the inner surface U is a space S2, and the size of the gap is a height H2. When the thickness of the lighting fixture 100 is smaller than the height H2, when the lighting fixture 100 is embedded in the embedding hole C, the lighting fixture 100 can be embedded in the mounting surface B in a flat state.

  The lighting fixture 100 includes a fixture body 1, a fluorescent lamp 2, an arc tube 3, a ballast 4, a flange-shaped electrode 5, and a socket 6. In addition, a terminal block 7 and a terminal block holder 8 are provided outside the instrument body 1.

  When the fluorescent lamp 2 is attached to the fixture body 1 of the lighting fixture 100, the fixture body 1 and the fluorescent lamp 2 are fitted with almost no gap. The luminaire 100 is embedded in an attachment surface B such as a ceiling, for example, and the attachment surface B and the fluorescent lamp 2 are in a flat state.

  The fluorescent lamp 2 includes a U-shaped arc tube 3 inside. The fluorescent lamp 2 is in the shape of a GX53 base in which the ballast 4 is built in, and it is not necessary to provide the ballast 1 in the fixture body 1, and the overall height of the lighting fixture 100 can be reduced.

  The fluorescent lamp 2 is attached to a socket 6 provided on the bottom surface of the instrument body 1. The socket 6 is provided with a dharma hole at a position corresponding to the two flange-shaped electrodes 5 of the fluorescent lamp 2, and the fluorescent lamp 2 can be attached to the instrument main body 1 by fitting the flange-shaped electrode 5. . At the same time, the fluorescent lamp 2 and the luminaire main body 1 can be electrically connected.

  The luminaire 100 includes a terminal block 7 for connecting the fixture body 1 and an external power source. As shown in FIG. 4, the terminal block 7 includes a power line insertion slot 71 for inserting an external power line, and a release button 72 for removing the inserted power line from the terminal block 7. By providing the terminal block 7 so that the release button 72 faces a surface other than the surface facing the inner surface U, there is no risk of contact when the lighting fixture 100 is embedded, and the power line is prevented from being released.

  The terminal block holder 8 includes a terminal block 7 at the tip, and the other end is supported by the instrument body 1. The terminal block 7 electrically connects the instrument main body 1 and the outside via the terminal block holder 8. The terminal block holder 8 is made of metal and has flexibility. For example, it is an alloy mainly composed of iron, and is formed of austenitic stainless steel containing 8 to 10% Ni (nickel) and 18 to 20% Cr (chromium).

  As shown in FIG. 3, the terminal block holder 8 is supported by a fastener 81 outside the instrument body 1, and the other end can be displaced in a direction in which the terminal block holder 8 is flexible. The terminal block 7 is fixed and held on the side where the terminal block holder 8 can be displaced. Not only when a load is directly applied to the terminal block holder 8, but also when the terminal block 7 is displaced by applying some load, the terminal block holder 8 is provided on the side provided with the terminal block 7 from the fastener 81. May be bent and bent.

  FIG. 5 is a schematic diagram illustrating a procedure for mounting the embedded lighting fixture according to the embodiment in an embedded location. 5 (a), 5 (b), and 5 (c) show a stage in the middle of attachment, and FIG. 5 (d) shows a state of attachment.

  When attaching the lighting fixture 100, first, the terminal block 7 protruding outside the fixture main body 1 is inserted into the embedding hole C, and the fixture main body 1 is inserted obliquely. This situation is shown in FIG.

  Next, the instrument body 1 is embedded in the embedding hole C. More specifically, the instrument body 1 is raised as perpendicular to the embedded hole C as possible and inserted. A case where the terminal block holder 8 is formed of a hard material and does not deform (when it is not bent) is shown by a dotted line in FIG. When the terminal block holder 8 is not deformed, the terminal block holder 8 is caught in the embedded hole C, and the gap between the side surface of the instrument body 1 on the side provided with the terminal block holder 8 and the embedded hole C is made as small as possible. The instrument body 1 cannot be inserted into the embedded hole C. In order to insert, there is a problem in shape limitation and appearance, such as rounding a part of the shape of the instrument body, or increasing the gap with the instrument body 1 by enlarging the embedded hole C.

  The terminal block holder 8 shown in FIG. 5B can be deformed by applying a force, and the terminal block holder 8 is directed from the space S2 to the space S1 with the position of the fastener 81 as a fulcrum. Bend. Therefore, the gap between the side surface of the instrument main body 1 on the side provided with the terminal block holder 8 and the embedded hole C can be reduced, and the instrument main body 1 can be inserted with being vertically raised with respect to the embedded hole C.

  FIG. 5C shows a state in which the instrument main body 1 is gradually raised and the instrument main body 1 is inserted into the embedded hole C as in FIG. When the height H2 is small and the inner surface U of the embedding location is close to the attachment surface B, the terminal block holder 8 may hit the embedding hole C and the terminal block 7 may hit the inner surface U. As shown in FIG. 5C, the terminal body holder 8 is deformed by bending or bending, so that the instrument body 1 can be inserted into the embedded hole C.

  FIG. 5D shows a state when the instrument main body 1 is attached to the embedded hole C of the attachment surface B. As illustrated, when the height H2 of the embedding location is small, the inner surface U and the terminal block 7 are in contact with each other, and the terminal block 7 is always subjected to a load from the inner surface U. When the terminal block holder 8 is deformed and the position of the terminal block 7 fixed at the tip is displaced, the lighting fixture 100 can be mounted on the mounting surface B in a flat state.

  When the terminal block 7 is provided directly on the bottom surface of the fixture body 1, at least the height H1 (see FIG. 2) of the gap between the luminaire 100 and the inner surface U that is closest to each other is the height of the terminal block 7 body. It had to be bigger than that. However, in the present embodiment, since the terminal block mounting portion of the terminal block holder 8 can be displaced with the support portion as a fulcrum, the height H1 may be smaller than the height of the terminal block 7 body. Even when the height H1 is infinitely equal to zero, the lighting fixture 100 can be attached to the attachment surface B in a flat state depending on the shape and material of the terminal block holder 8.

  As described above, according to the present embodiment, by providing the terminal block holder 8, the terminal block 7 can be moved and moved in the vertical direction of the side surface of the apparatus main body 1, so that the lighting apparatus 100 can be moved. Can be made substantially the same as the height of the fixture body 1, and the height of the lighting fixture 100 can be suppressed. Therefore, it is possible to provide a lighting fixture that can be attached even in a place where the embedded height is small.

  In the present embodiment, the terminal block 7 attached to the terminal block holder 8 is installed so as to face the inner surface U side. When the difference between the height of the instrument main body 1 and the height of the terminal block 7 main body is small, the degree of deformation of the terminal block holder 8 can be reduced by installing the terminal block 7 so as to face the inner surface U side. Therefore, it is preferable. However, if the terminal block holder 8 is deformed and the lighting fixture 100 can be mounted on the mounting surface B, the terminal block 7 may be installed so as to face the mounting surface B. When the terminal block 7 is installed on the mounting surface B side, the terminal block 7 is mounted so that the release button 72 is disposed on a surface other than the surface facing the mounting surface B. When the difference between the height of the instrument body 1 and the height of the terminal block 7 body is large, the terminal block 7 may be provided on either the mounting surface B side or the inner surface U side.

  Further, in addition to fluorescent lamps, the present invention can also be applied to an embedded lighting fixture that uses an incandescent bulb, a light emitting diode, a halogen lamp, or the like as an arc tube. Not only the type of light source but also the socket is applicable not only to the above-described example (GX53 socket). In particular, the present invention is effective when the embedded height and the height of the lighting fixture are substantially equal and the height from the bottom portion of the lighting fixture to the inner surface is small. Furthermore, when the height from the mounting surface to the inner surface is small and the socket and the arc tube are combined, the effect is great.

  In addition, the shape and type of the above-described embedded lighting fixture, the shape and material of the terminal block holder, the mounting position, and the like are merely examples, and can be arbitrarily changed and modified.

  Other suitable modifications of the present invention include the following configurations.

  With respect to the embedded illuminator according to an aspect of the present invention, preferably, the terminal block holder holds the side including the terminal block movably in the mounting direction of the luminaire main body.

  Preferably, the terminal block holder is made of a flexible material, and is itself bent to hold the terminal block movably.

Preferably, the terminal block includes a release button for removing the power line,
The release button is arranged on a surface other than a surface perpendicular to the mounting direction of the lighting fixture body.

  More preferably, a GX53 socket is provided.
