Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a support that can favorably support an annular lamp, particularly a small annular lamp.

Structure of conventional examples and their problems Conventionally, some of the supports used for annular lamps are those made by bending elastic wires, but since the lamp diameter is quite large, it is necessary to compensate for the strength of the wires. Many have complex structures,
There were problems such as the processing was troublesome and it took time to attach and detach the lamp. By the way, with the recent development of a 9W type compact annular fluorescent lamp as a light source suitable for small decorative lighting equipment, it was necessary to develop a support using a wire due to the mounting space for the support. Since the diameter of the lamp is small, a relatively simple structure that can support the lamp well has been desired.

OBJECTS OF THE INVENTION The present invention has been made in response to the above-mentioned needs, and it is an object of the present invention to provide a support for an annular lamp that can particularly favorably support a small annular lamp and that can be easily attached and detached.

Structure of the Invention In order to achieve the above-mentioned object, the present invention is made of an elastic wire material formed into a substantially U-shape, with both ends serving as mounting portions, and parallel portions on both sides facing the substantially U-shaped forming surface. It is bent in a substantially right-angled direction to form a substantially U-shaped bent portion, and arc-shaped support portions are formed on both sides of this bent portion in the same plane as the bent portion, and these support portions allow the inside of the annular lamp to be supporting the periphery;
The intermediate portion connecting the arc-shaped support portions on both sides of the bent portion constitutes a support for an annular lamp characterized in that it is located inward from the inner peripheral edge of the lamp, and has a relatively simple structure and is easy to process. facilitate,
The lamp can be attached and detached simply by elastically deforming the bent portion inward.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a lighting fixture to which the support of the present invention is applied, in which a translucent globe 4 is attached to the bottom surface of a box-shaped chassis 2 attached to a ceiling surface 1 via a fixture 3. 4 houses an annular lamp 7 attached to the lower surface of the chassis 2 via a support 6 attached with screws 5. A cord 9 having a connector 8 is inserted from the underside of the chassis 2.
The connector 8 is connected to the annular lamp 7.

2 to 5 show the main parts of the present invention, and the support 6 is formed of a wire such as an elastic metal wire in a substantially U-shape, with both ends bent at right angles, and The part is formed into a mounting part 10 which is curled so that the screw 5 passes through, and parallel parts 1 on both sides are formed.
1 is bent in a direction substantially perpendicular to the substantially U-shaped forming surface to form a substantially U-shaped bent portion 12, and on both sides of this bent portion 12, in the same plane as this bent portion 12, arc-shaped forming support parts 13, supporting the inner peripheral edge of the annular lamp 7 by these support parts 13;
An intermediate portion connecting the arc-shaped support portions 13 on both sides of the bent portion 12 is located inward from the inner peripheral edge of the lamp 7 .

When attaching and detaching the annular lamp 7 from the above-mentioned support 6, if you hold the bent part 12-12 between your index finger and thumb and elastically deform it as shown by the dotted line, the inner diameter of the annular lamp 7 This can be done easily because the outer diameter formed by the portion 13 is narrowed to a sufficiently small size.

Further, 14 is a conductive pin, which is connected to the connector 8. Incidentally, since the outer diameter and inner diameter of the 9W type annular fluorescent lamp are 120 mm and 80 mm, respectively, the appropriate distance between the bent portions 12 is about 50 mm.

Effects of the Invention The present invention has the above configuration and is formed by applying a relatively simple bending process to an elastic wire.
It can be manufactured at a low cost, supports the annular lamp well without wobbling, and has excellent effects such as easy attachment and detachment of the lamp.
