Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device, and its purpose is to provide wide range illumination and localized illumination.

That is, the present invention has a main body universal joint attached to a mounting portion so as to be horizontally rotatable, a plurality of arms attached to the main body universal joint so as to be vertically rotatable, and a lamp universal joint rotatably attached to the tips of these arms. It is characterized in that the lamp is attached to the lamp universal joint so as to be rotatable and slidable.

Therefore, the lamp can be rotated in various ways with respect to the mounting part via these universal joints, and various localized and wide-range illuminations can be achieved.

FIG. 1 is a perspective view of an embodiment of the lighting fixture of the present invention.

In the figure, 1 is a hanging pipe, 2 is a mounting bracket, 3 is a flange, 4 is a main unit universal joint, and 5a.

5b is the arm, 6 is the lamp universal joint, 7 is the bow-shaped pipe, 8
, 9 are holders, and 10a and 10b are fluorescent lamps.

The main body universal joint 4 has a structure shown in FIGS. 2 and 2A.

That is, the hanging pipe 1 is passed through the drum 11, and the pin 12
is passed through the hanging pipe 1 to prevent it from being pulled out.

A rod 13 having a bent part that serves as a relief part for the hanging pipe 1 is inserted into the drum 11, and a drum 14 and a U-shaped metal fitting 15 on the drum side are fastened to the rod 13 with a nut 16.

Further, although not shown, the arm 5a is fixed to the drum 14, and the arm 5b is attached to the drum side U-shaped metal fitting 15 with a bolt 1.
7 and a tightening nut 18 to be rotatably tightened.

In this case, the drum 14 is rotatable relative to the drum 11 and the U-shaped metal fitting 15 on the drum side.

The lamp universal joint 6 has a structure shown in FIG. 3.

That is, the lamp-side U-shaped metal fittings 19 are rotatably attached to threaded portions formed at the ends of the arms 5a and 5b.

The drum 20 divided into two parts is held between the lamp-side U-shaped metal fitting 19, and the hole 19a of the lamp-side U-shaped metal fitting 19 and the drum 20 are
Insert the bolt 21 into the hole 20a and tighten with the nut 22.

Prior to this tightening, the groove 20b between the divided portions of the drum 20 is
Pass the bow-shaped pipe 7 through.

Therefore, by adjusting the tightening force of the nut 22, the drum 20 rotates about the bolt 21 and the arcuate pipe 7 slides.

With this configuration, in FIG. 1, the main body universal joint 4 rotates on a horizontal plane centering on the hanging pipe 1, and the arms 5a and 5b rotate on a vertical plane with the rod 13 and bolt 17 as rotation axes, respectively. Rotate.

Also, a fluorescent lamp 10a. 10b is arm 5a, 5b
It rotates around the bolt 21 as an axis, and also rotates and slides around the bolt 21 on a vertical plane.

FIG. 4A shows the fluorescent lamps 10a and 10b from the state shown in FIG.
FIG. 4B is a plan view of the front view when it is turned downward and slid outward.

5A is a front view of the state shown in FIG. 1 in which the fluorescent lamp 10b is rotated horizontally around the arm 5b with the arm 5b left as it is, and then the arms 5a and 5b are suspended, and FIG. 5B is a front view of the state shown in FIG. FIG.

FIG. 6 is a plan view of the state in which the main body universal joint 4 has been moved upward along the suspension pipe 1 from the state shown in FIG. 5A and fixed with a pin or the like.

For this reason, a through hole is provided on the lower surface of the drum 11 to allow the hanging pipe 1 to pass therethrough.

Although a straight tube fluorescent lamp was used in the embodiment, a round fluorescent lamp or an incandescent lamp may also be used.

As described above, the lighting equipment of the present invention is shown in FIGS. 1 and 4A.
Diffuse illumination can be performed as shown in FIGS. 5A and 4B, and concentrated illumination can also be performed as shown in FIGS. 5A, 5B, and 6.

Furthermore, since it is foldable, it can be packed compactly.
