Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an embedded luminaire such as a downlight.

[0002]

[Prior Art]

 Conventionally, in an embedded lighting fixture such as a downlight, for example, a locking piece is projected downward from the facing outer surface of the lighting equipment main body, and the mounting to the ceiling board is provided on the ceiling board. The main body of the luminaire is inserted into the opening, and the locking piece is locked on the upper surface of the opening edge of the opening, so that the attachment can be done. This is done for the terminal block placed regardless of the position of the locking piece. That is, the position of the terminal block is provided on the outer surface of the luminaire main body so as to be adjacent to the locking piece so as to avoid the position of the locking piece.

[0003]

[Problems to be solved by the device]

 However, in the conventional example described above, when the electric wire is connected to the terminal block after the luminaire main body is installed in the opening, the terminal block holds the luminaire main body when the electric wire is inserted into the terminal block. Since the lighting fixture body is pushed in the direction where the locking piece is not provided because it is arranged on the side of the locking piece, the lighting equipment body easily tilts or shifts its position, As a result, there is a problem in that the peripheral edge of the opening is damaged. Further, even when the feed wiring is performed, the main body of the luminaire is easily tilted when the electric wire is pulled, and this also causes a problem that the peripheral edge of the opening is damaged.

The present invention is intended to solve the above-mentioned problems, and provides an embedded lighting device that can be easily wired without damaging the mounting portion of the lighting device body. Is what you are trying to do.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, according to the present invention, a lighting fixture main body 3 is inserted into an opening 2 provided in a ceiling plate 1 and embedded in the ceiling plate 1. Type lighting fixture, in which a flange 4 that is locked to the lower surface of the opening edge of the opening 2 is provided at the bottom of the lighting fixture main body 3 that is to be inserted into the opening 2, and lighting is performed above the flange 4. A spring piece 5 having elasticity is projected from the opposite outer side of the device body 3 obliquely upward, and a terminal block 6 for connecting an electric wire is provided on the surface on the side where the spring piece 5 is projected. ..

[0006]

[Action]

 Then, the spring piece 5 is locked to the opening edge of the opening 2, and the flange 4 is brought into contact with the lower surface of the opening edge of the opening 2, whereby the lighting fixture body 3 is attached to the opening 2. Then, an electric wire is inserted into the terminal block 6 from the direction in which the spring piece 5 is provided to connect the electric wire to the lighting fixture body 3.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIG. 1, the embedded luminaire is mainly composed of a luminaire main body 3 and an elastic spring piece 5 protruding from the outer surface of the luminaire main body 3. Reference numeral 7 denotes a guide tube projecting from the lower portion of the luminaire main body 3 so that the light from the lamp 8 can be guided in a predetermined direction.

The luminaire main body 3 is composed of a lower case 3a and an upper case 3b which are connected and fixed by a fastener 9, and a lamp 8 and a reflector plate 10 are housed in the lower case 3a. The lamp support 11 is housed and arranged in 3b. A flange 4 is provided on the lower end of the lower case 3a so as to project laterally. The flange 4 has an opening edge of an opening 2 provided in the ceiling plate 1 into which the lighting fixture body 3 is inserted. It is designed to come into contact with the bottom surface. From the opposing outer sides of the lower case 3a constituting the luminaire main body 3, spring pieces 5 having elasticity are provided so as to project obliquely upward above the flange 4.

A mounting piece 5 a is provided at one end of the spring piece 5, and the mounting piece 5 a is connected and fixed to the outer surface of the lower case 5 a by a fixing tool 12 so that the spring piece 5 is directed obliquely upward. It is projected. A terminal block 6 for wire connection is attached to the outer surface of the upper case 3b constituting the luminaire main body 3 on the side on which the spring piece 5 projects. The terminal block 6 has a quick-connect terminal 13 built-in, and the wire B can be connected only by inserting the cable B into the terminal block 6.

As shown in FIG. 2, the embedded luminaire is constructed such that the luminaire main body 3 is inserted into the opening 2 provided in the ceiling plate 1 in a state where the spring piece 5 is bent to illuminate the luminaire. The flange 4 projecting from the lower part of the instrument body 3 is locked to the lower surface of the opening edge of the opening 2, and the spring piece 5 projecting from the outer surface of the lighting instrument body 3 is locked to the opening edge of the opening 2. By doing so, the opening 2 is attached.

When the lighting fixture main body 3 is attached to the opening 2 after the electric wire B is connected to the terminal block 6, as shown in FIG. The spring piece 5 protruding in the pulling direction of the electric wire a can be attached to the opening edge by locking the spring piece 5 to the opening 2 because it is arranged on the side of the opening 2. The position of 5 is easy to determine and easy to construct. In addition, when the wire a is connected to the terminal block 6 after the lighting device main body 3 is attached to the opening 2, by inserting the wire a into the terminal block 6, the lighting device main body 3 is moved to the side. The attempt to shift the position can be absorbed by the strip 5, so that the peripheral edge of the opening 2 is not scratched.

[0012]

[Effect of the device]

 As described above, according to the present invention, a flange that is engaged with the lower surface of the opening edge of the opening is provided in the lower portion of the main body of the lighting apparatus to be inserted into the opening, and the flange of the lighting apparatus faces above the flange. A spring piece with elasticity is projected obliquely upward from both sides, and a terminal block for connecting wires is provided on the surface on the side where this spring piece is projected, so the illuminator body is attached to the opening. Even if you connect the wires after inserting them into the terminal block, the terminal block is located on the surface on which the spring pieces project, so the bending force of the spring pieces causes the lighting fixture to tilt significantly. However, it is possible to prevent the displacement, and it is possible to connect the electric wire to the terminal block without damaging the peripheral portion of the opening. In addition, even if the terminal block is pulled sideways together with the electric wire in the case of feed wiring, it can be absorbed by the bending force of the spring piece, and the luminaire body can be greatly tilted or misaligned. Can be prevented. In addition, when the main body of the luminaire is attached to the opening after connecting the wire to the terminal block, the terminal block is located on the surface on the side where the spring piece is projected, so the direction of the wire is the same as the drawing direction. It is possible to attach the spring piece projecting from the to the edge of the opening, and it is easy to decide the mounting position of the spring piece and to perform the construction easily.
