Description

[Detailed description of the invention] This invention relates to a lighting fixture, and its purpose is to provide a lighting fixture with a simple structure in which the irradiation direction can be freely changed by tilting the socket base, and the socket base can be easily attached and detached. It is.

An embodiment of this invention is shown in FIGS. 1 to 5.

That is, this lighting device includes a disc-shaped socket base 2 in which a socket 1 is provided, and notch holes 3 and 4 that are arranged facing each other and into which mutually opposing edges 2a and 2b of the socket base 2 are inserted. It is equipped with a pair of socket base receiving pieces 5 and 6.

7 is a light bulb attached to socket 1.

The socket base receiving pieces 5 and 6 are formed in an inverted shape and have a mounting hole 8 in the upper surface.

The socket base receiving piece 5.6 is fixed to a ceiling surface or the like with a screw inserted into the mounting hole 8.

The notch holes 3.about.4 of the socket base receiving pieces 5, 6 are formed into elongated holes having arcuate ends.

The socket base receiving pieces 5 and 6 are elastic and made of stainless steel or a spring material.

It is desirable that the periphery of the notch holes 3 and 4 of the socket pedestal receiving pieces 5 and 6 and the outer periphery of the socket pedestal 2 be curled.

With this structure, the socket base 2 can be freely tilted by swinging within the notch holes 3 and 4 of the socket I and base receiving pieces 5 and 6.

At this time, the socket base 2 is
Since it is held elastically between the two, the tilted angle will be maintained even if you release your hands.

Moreover, since the socket stand 2 is disk-shaped, it can freely rotate within a range of 360 degrees between its centers.

Therefore, when the socket 1 is provided with a reflective cover or the like, the direction of reflection can be changed by rotating the socket base 2.

In this way, the irradiation direction can be easily changed.

When attaching and detaching the socket base 2, use the socket base receiving pieces 5 and 6.
Since it has elasticity, it can be easily attached and detached by bending it as shown in FIG.

Therefore, installation can be easily carried out by fixing only the socket holder pieces 5 and 6 to a ceiling plate or the like and then attaching the socket pedestal 2.

Further, by installing a large number of socket base receiving pieces 5 and 6 side by side, the socket base 2 can be freely replaced as needed.

Incidentally, if the notch holes 3 and 4 of the socket pedestal receiving piece 5.6 and the outer peripheral edge of the socket pedestal 2 are curled, the socket pedestal 2 can be rotated and swung smoothly.

The swing range of the socket stand 2 is determined by changing the shape of the notch holes 3 and 4 to the sixth position.
It can be easily changed by forming it into an oval shape as shown in the figure or a circular shape as shown in FIG. 7, thereby making it possible to freely obtain a variable range of the irradiation direction.

In the case of the example shown in FIG. 6, the upper and lower edges of the cutout hole 3.4 act as stoppers, and by determining the upper and lower width A thereof, the range in which the irradiation angle can be changed can be regulated.

In the case of the example shown in FIG. 7, the socket base 2 can be rotated through 360 degrees.

When the locking protrusion 9 is provided on the periphery of the socket base 2 as shown in FIG. 8, the rotation range of the socket base 2 is can be regulated.

In this case, the rotation range can be changed by varying the width of the locking protrusion 9.

FIG. 9 shows a modification of the socket base receiving piece.

That is, a pair of cut and raised pieces provided on the mounting plate 10 form the socket base receiving pieces 5' and 6'.

11 is a mounting hole provided in the mounting plate 10.

This configuration has the advantage that the installation of the socket pedestal receiving pieces 5, 6 is simple, and that the mounting condition is stable because the spacing between the socket pedestal receiving pieces 5', 6' is determined by pressing.

The rest is the same as the first embodiment. As described above, in the lighting device of this invention, a pair of elastic socket base receiving pieces each having a notch hole are arranged facing each other, and a disc-shaped socket base provided with a socket is inserted into the notch hole of both socket base receiving pieces. Since the socket pedestal holder piece is engaged with and held in place, the lamp irradiation angle can be changed by freely swinging or rotating the socket pedestal holder piece, and the socket holder piece can be easily bent. It has the advantage of being removable and having a simple structure.
