[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position-adjustable balanced lighting device installed indoors such as in a store or a house.

[0002]

2. Description of the Related Art Lighting fixtures installed in stores, houses, and the like include a suspension type that hangs from a ceiling and a direct attachment type that is directly attached to a ceiling or the like. It is a target.

[0003]

[Problems to be Solved by the Invention] However, in the above-described fixed arrangement, when the lighting position is changed due to a change in the arrangement of a table or the like, a hook or the like attached to the ceiling is removed and the hook or the like is moved to the changed position. Lighting fixtures have to be replaced after installation, which is a tedious and laborious operation.

The present invention has been made to solve the above-mentioned problems, and its purpose is to make it possible to change the lighting position very easily and to freely change the lighting position to an arbitrary position. It is an object of the present invention to provide a balanced lighting device capable of performing the following.

[0005]

A balance type lighting device according to the present invention comprises a light emitting section, a rod member, a balance weight, and a support member, and a light emitting section is attached to one end of the rod member. Attach the balance weight slidably to the other end. The support member is attached to a hook or a wall surface of a ceiling, and slidably supports the rod member between the light emitting unit and the balance weight.

[0006] The support member includes a member through which the rod member is inserted,
The rod member is configured to be rotatable by rotating with respect to this member, and the light emitting unit is configured to be rotatable around the support member as a rotation center.

The light-emitting portion is provided with a shade made of a perforated panel such as a punching metal or a translucent panel such as an acrylic plate, so-called semi-direct illumination.

[0008]

In the above configuration, in the case of a ceiling hanging type, the lighting device is hung by attaching a support member to a hook. When the lighting position is changed due to a change in the arrangement of a table or the like, the rod member is moved linearly with respect to the support member to move the light emitting unit to a desired lighting position, and the balance weight is moved along the rod member. Move to balance with the light emitting part. Further, the light emitting unit is swiveled by turning the rod member right and left around the support member. This makes it possible to very easily and freely change and move the light emitting portion to an arbitrary position after the lighting fixture is attached.

[0009] Since the shade of the light emitting section is made of a perforated panel or a translucent panel, the lower part is efficiently irradiated with concentrated light, the ceiling is partially irradiated with transmitted light, and the direct illumination is indirectly illuminated. , And a well-balanced illumination can be obtained.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. This is an example of a type of lighting fixture suspended from a ceiling. The lighting fixture of the present invention is shown in FIGS.
As shown in the figure, the light emitting unit 1 includes a shade 2, a rod member 3 having a predetermined length, a balance weight 4 having a predetermined weight, and a support member 5 for supporting these.

The light emitting section 1 comprises a lamp 1A and an electric apparatus section 1B having a dimmer (light control circuit) and the like. The electric apparatus section 1B is fixed to one end of a rod member 3, or the electric apparatus section 1B is a rod member. 2 is mounted so as to be rotatable around the center of rotation. As the lamp 1A, for example, a halogen lamp of 150 W (100 V) is used, and a sufficient illuminance can be obtained with a small light source.

The shade 2 is a molded product of a perforated metal panel (punched metal) made of steel or aluminum or a translucent plate such as an acrylic plate, and is used for semi-direct illumination or semi-indirect illumination. For example, the porosity or transparency is such that the reflection is 80% (downward light) and the transmission is 20% (upward light).

The lamp 1A and the shade 2 are not limited to those shown in the figure. For example, a reflecting dish may be provided below the lamp 1A, or the shade 2 may be hung from the electric device 1B. It goes without saying that various types such as a hanging type can be used.

The rod member 3 is a round pipe made of chrome-plated steel having a length of about 1 to 1.2 m, and is inserted into and supported by a support member 5 described later so as to be slidable. A balance weight 4 is slidably mounted on the opposite side of the light emitting unit 1 with the support member 5 of the rod member 3 interposed therebetween.

The balance weight 4 has a cylindrical shape made of chrome-plated steel, and has such a weight that the light-emitting portion 1 can be balanced even when the light-emitting portion 1 projects as described later.
A flange-like stopper 6 is provided at the balance weight side end of the rod member 3 to prevent the balance weight 4 from falling off.

The supporting member 5 is a member formed by chrome-plating steel, and includes a horizontal supporting member 5A and a vertical supporting member 5A.
B and a suspension ring 5C (or suspension chain).

The rod member 3 is slidably inserted into and supported by the horizontal support member 5A.

The vertical support member 5B is rotatably mounted on the upper surface of the horizontal support member 5A by means of concave and convex fitting as shown in FIG. 3 (a), or as shown in FIG. 3 (b). Into 5B 'and 5B ", and the upper part 5B'
Is rotatably attached to the lower portion 5B "by means of concave and convex fitting so that the rod member 3 can be swiveled right and left around the support point as a center of rotation. The suspension ring 5C is connected to the vertical support member 5B or 5B.
Attached integrally to the upper surface of B ′ and hooked on hook F.

In the above configuration, the hook F is attached to a predetermined position on the ceiling, and the hanging ring 5C is hooked on the hook F to suspend the lighting fixture. With the change in the arrangement of the table and the like, the rod member 3 is linearly moved back and forth with respect to the support member 5, and is further turned left and right about the support member 5 as necessary. The balance weight 4 is moved back and forth as the rod member 3 moves back and forth to balance with the light emitting unit 1. Thereby, the illumination position can be freely changed within a range of a circle having a radius of about 1 to 1.2 m.

In addition, an efficient downward concentrated light is radiated by the perforated or translucent shade 2 of the light emitting portion 1, and at the same time, an indirect illumination to the ceiling surface is added, thereby providing a well-balanced illumination.

Although the above description has been given of a lighting device of a type hanging from a ceiling, it is needless to say that the present invention can be applied to a lighting device of a type fixed to a ceiling, a wall or the like.

[0022]

As described above, in the balance type lighting apparatus according to the present invention, a light emitting unit is attached to one end, and a balance member is slidably inserted into the support member at the other end. In addition, since the rod member is configured to be able to turn left and right with respect to the support member, the lighting position can be extremely easily adjusted by simply moving the rod member linearly or turning left and right when changing the arrangement of the table or the like after mounting the lighting fixture. It can be changed, and the lighting position can be freely changed to any position.

Further, by using a perforated panel or the like for the shade of the light emitting section, a well-balanced illumination can be obtained.
