Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminaire in which a pair of lamps are supported on the upper part of a pillar standing upright from the main body of the luminaire.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional luminaire 1. In this figure, this lighting fixture 1 is a so-called desk-type desk lamp, and a fixture 3 for fixing to the edge of a desk lamp, a column 5 standing upright from this fixture 3, and an upper end of the column 5. Arm 7 which is rotatably supported by a section, and a pair of lamp bodies 9 and 1 which are rotatably connected to the tip of the arm 7 along the horizontal direction.
0, and a lighting device (inverter circuit or the like) (not shown) for lighting the lamps supported by the lamp bodies 9 and 10 is built in the pillar 5. The electric wire 13 for power supply from the lighting device is inserted into the arm 7 and once pulled out to the outside, and then connected to the lamps of the lamp bodies 9 and 10.

In such a lighting fixture 1, the lamp bodies 9 and 10 are rotated around the tip of the arm 7 in the direction of arrow a,
By rotating the arm 7, the illumination range can be widened and the illumination position can be changed.

[0004]

However, in the above-described lighting device 1, when changing the illumination range or the illumination position of the lamp bodies 9 and 10, it is necessary to rotate the lamp bodies 9 and 10 respectively, which is troublesome. , The angle of rotation of the light bodies 9, 10 is 0 °
There is a problem that a V-shape is formed between 180 degrees and the lighting range is wide, but a space for the lamp body is required.

When the arm 7 is rotated with respect to the support column 5 or the lamp bodies 9 and 11 are rotated around the tip of the arm 7, the electric wire 13 drawn from the lighting device is twisted or bent. There is a risk of disconnection.

Therefore, an object of the present invention is to provide a lighting fixture which can easily change the illumination range and the illumination position and which is not broken even if the illumination range and the illumination position are changed.

[0007]

In order to achieve the above-mentioned object, the invention of claim 1 is to provide an instrument main body, a pillar standing upright from the instrument main body, and a pair of lamp bodies supported in parallel on the upper part of the pillar. And a lighting device provided with a lighting device electrically connected to these lamps and lighting the lamps, in which relative movement means of lamps moves one lamp to the other by moving the other lamp. Is provided between the support column and the lamp body.

According to a second aspect of the present invention, the lamp body relative movement means according to the first aspect is rotatably supported on the upper end of the column, and has a gear having a conductive portion electrically connected to the lighting device. Each of them is installed in the lamp body and meshes with the gear,
It is characterized in that it is composed of an electrical connection body that is electrically connected to the conductive portion of the gear.

[0009]

In the luminaire according to the first aspect, when one of the pair of lamp bodies is moved, the other lamp body is moved by the lamp body relative movement means to the opposite side to the moving direction of the one lamp body.
Therefore, the illumination range and the illumination position can be easily changed by moving only one of the lamp bodies.

In the luminaire according to the second aspect, when one of the pair of lamp bodies is moved, a gear that meshes with the electric connection body of the one lamp body rotates, and the other lamp in which the electric connection portion meshes with this gear. The body moves in the direction opposite to the moving direction of one of the lights.
This makes it possible to easily change the illumination range and illumination position of the lamp body.

Further, the pair of lamps and the lighting device are electrically connected to each other by connecting the conductive portion of the gear and the electric connector of the lamp. Therefore, an electric wire for electrically connecting the lighting device and the lamp body is not required. Therefore, even if the pair of lamp bodies are moved, there is no disconnection.
