Description

  The present invention relates to an embedded illumination device that employs a rivet structure in a portion that connects a connecting arm extending from a light emitting unit main body side and a connecting arm extending from a power supply unit side.

  In the conventional embedded illumination device, the light emitting unit main body and the power supply unit for controlling the lighting of the light emitting unit main body are integrated in the same casing. However, when the power supply unit is built in the upper part of the light emitting unit main body, the height of the embedded lighting device increases, and there is a problem that installation becomes difficult when the space behind the ceiling of the installation building is narrow. It was.

  In order to solve this, the power unit is disconnected from the light emitting unit main body of the embedded lighting device, and the light emitting unit main body and the power unit are connected by a power cable, thereby suppressing the height of the embedded lighting device, Even in the case where the space behind the ceiling is small, there has been an apparatus in which the embedded illumination device can be easily installed.

  However, if the light-emitting unit body and the power supply unit are connected by a power cable, accidents such as pulling the power supply unit during installation work can easily occur, and the power cable can be easily broken. When the connector is connected to the connector, the connector connection may be incomplete and the embedded lighting device may malfunction.

  Therefore, the built-in lighting that physically connects the light-emitting unit body and the power supply unit with the connecting arm and that can move the power supply unit at the connecting part of the connecting arm to avoid breakage of the power cable and poor connector connection. There was also a device. (For example, see Patent Document 1)

Embodiment 1 FIG.
Hereinafter, the structure of the embedded illumination device 1 according to the first embodiment of the present invention will be described with reference to FIGS.
A ceiling-embedded embedded lighting device 1 as a lighting device is housed in the back of the ceiling from a circular embedded hole formed in the ceiling surface. It is mainly composed of a fixed portion 4 that is fixed and a power supply unit 3 that is movably connected to the fixed portion 4.

  As shown in FIG. 2, the light emitting unit body 2 includes an umbrella-shaped heat radiation fin 2a, a light emitting surface 2b arranged inside the heat radiation fin 2a, and a decorative frame 2c formed so as to surround the outer periphery of the light emitting surface 2b. And an annular flange 2d formed so as to surround the outer periphery of the decorative frame 2c, and two attachment leaf springs 2e connected to the upper side surface of the annular flange 2d and extending in a band shape.

The heat radiating fins 2a are for escaping heat generated from the light emitting part by heat conduction, and are made of aluminum die cast that has high heat radiating properties and excellent heat conductivity and workability.
The light emitting surface 2b has a disk shape, and an LED module substrate on which a plurality of LEDs that are solid state lighting are arranged, an organic EL, and the like are arranged. In the case of using an LED module substrate, the light emitting surface may be covered with a diffusion plate made of resin or glass material.

  The decorative frame 2c has a role of controlling light emitted from the light emitting surface, and a highly reflective white resin material or the like is used. The annular flange 2d is for improving the appearance of the mounting surface when the light emitting unit body 2 is installed on the ceiling. The two mounting leaf springs 2 e are provided as fixing brackets for fixing the light emitting unit main body 2 on the ceiling plate 11, and are attached to the back side of the ceiling plate 11. Note that the two leaf springs 2e for attachment may be changed to three for further improving the stability, and the system may be arbitrarily selected.

The fixing | fixed part 4 is comprised from the rectangular main sheet metal 4a and the connection arm 5 (1st connection arm), as shown in FIG.3, FIG.4.
One end portion of the main sheet metal 4a in the longitudinal direction is fixed to the top plate plane of the radiation fin 2a of the light emitting unit main body 2 with a fastening member. In addition, a connecting arm 5 is fixed to the other end portion. The connecting arm 5 includes a pair of parallelogram-shaped parallelogram metal plates 5a extending obliquely downward from both sides in the longitudinal direction. Through holes 5b (first through holes) are formed in the two parallelogram sheet metals 5a at positions where they are opposed to each other at the tip portions.

As shown in FIGS. 3 and 4, the power supply unit 3 includes a main body member 9, a terminal block 7, support legs 8, and a connecting arm 10 (second connecting arm).
The main body member 9 is composed of a rectangular main sheet metal 9a and a side sheet metal 9b extending downward from both sides in the longitudinal direction. Therefore, the cross section in the short direction is a U-shape. A support leg 8 extending vertically downward is attached to one end of the main body member 9 in the longitudinal direction. Further, in the main body member 9, there is a portion where the side sheet metal 9 b does not exist within a predetermined distance from the support leg 8, and the terminal block 7 is attached to this portion.

Further, a connecting arm 10 composed of a pair of triangular triangular sheet metal 10a formed so as to extend from the side sheet metal 9b is fixed to one end portion of the main body member 9 in the longitudinal direction. There is a sloped sheet metal 9c existing between 10a. The two triangular sheet metals 10a are formed with through holes 10b (second through holes) at positions facing each other. The two triangular sheet metals 10 a are formed of the same member as the connecting arm 10.

  Then, the connecting arm 10 composed of the two triangular sheet metals 10a enters inward in the depth direction between the two parallelogram sheet metals 5a which are the connecting arms 5, the two through holes 5b and the two through holes. By passing one rivet 6 through 10b, the connecting arm 5 and the connecting arm 10 are movably connected.

As shown in FIG. 5, the rivet 6 is composed of a metal cylindrical portion 6a having a hollow inside, and a circular flat plate portion 6b integrally formed and fixed at both ends and having a radius twice as large as the cylindrical radius. It has been done.
After inserting the cylindrical portion 6a of the rivet 6 into the two through holes 5b and the two through holes 10b, the other end of the cylindrical portion 6a is crushed with a tool such as a pliers or a hammer into a flat plate shape. Thus, the flat plate portion 6b is formed so as not to fall out of the through hole 5b and the through hole 10b. The length of the metal cylindrical portion 6a after the other end is crushed is designed to be slightly larger than the distance between the two parallelogram sheet metals 5a.

Next, a flow of installing the embedded illumination device 1 in a circular embedded hole formed in the ceiling will be described with reference to FIGS.
First, as shown in FIG. 6 (STEP 1), the power supply unit 3 rotates inward about the rivet 6 and is inserted into the embedding hole from the rear end side of the power supply unit 3. As shown in FIG. 7 (STEP 2), when the embedded illumination device 1 is pushed up, the lower end of the side metal plate 9b and the upper peripheral edge of the embedded hole approach, and the upper end of the connecting arm 5 and the embedded hole The lower rim approaches. At this time, a gap is formed between the ceiling surface indicated by a dotted line assuming a space behind the ceiling and the rear end of the main sheet metal 9a.

  Next, as shown in FIG. 8 (STEP 3), the power supply unit 3 is pushed forward so as to be disposed in the space behind the ceiling. Then, the rear end of the main sheet metal 9a approaches the back of the ceiling with the lower end side of the side sheet metal 9b approaching the edge of the embedding hole. At this time, the upper end of the connecting arm 5 and the peripheral edge of the embedding hole are not in contact with each other, and a gap is formed.

Next, as shown in FIG. 9 (STEP 4), using the gap formed between the upper end of the connecting arm 5 and the peripheral edge of the embedding hole, while rotating around the axis of the rivet 6, The light emitting unit body 2 is pushed upward. Here, the support leg 8 at the lower end of the power supply unit 3 is placed on the back side of the ceiling plate 11 and a gap is again formed between the main sheet metal 9a and the ceiling surface indicated by a dotted line assuming a space behind the ceiling. .
Further, as shown in FIG. 10 (STEP 5), the power supply unit 3 is pushed into the space behind the ceiling while rotating the light emitting unit main body 2 around the axis of the rivet 6. When the support leg 8 is in contact with the back of the ceiling plate 11, the light emitting unit body 2 is pushed up to complete the installation as shown in FIG. 11 (STEP 6).

  Thus, in this Embodiment 1, since the connection arm 5 and the connection arm 10 were connected by one component called the rivet 6, the number of components can be reduced and it can manufacture at low cost.

  In the present embodiment, the other end of the cylindrical portion 6a of the rivet 6 is crushed by using a tool such as a pliers or a hammer to form a flat plate, but a plurality of cuts are made on the other end from the outer periphery toward the inside. The flat plate portion 6b may be formed so as to raise the notch after inserting the two through holes 5b and the two through holes 10b.
