Description

[Detailed Description of the Invention] This invention relates to a fluorescent lamp device, particularly a lamp device for annular fluorescent lamps.

Conventionally, for circular fluorescent lamps, the bases of multiple elastic metal supports are attached to the main body of the lamp equipped with a ballast, lighting tube, and switches using fasteners such as screws. Many have a structure in which a circular fluorescent lamp is supported by a curved part formed at the tip.

As mentioned above, the support that is attached to the lamp body with screws is usually made of a piece of metal plate, and in order to support an annular fluorescent lamp, at least three supports are required. In addition, the design of the lamp body is limited by the design of the lamp body, which makes the lamp body larger than necessary.
The disadvantage is that the logistics costs including packaging costs are high, and the number of parts is large, making it difficult to assemble for use.

The purpose of this invention is to eliminate the above-mentioned defects, reduce the size of the lamp body as much as possible, and provide a lamp that can be assembled very easily and reliably during use. .

Hereinafter, embodiments of this invention will be described based on the drawings.

In the figure, 1 is a cylindrical casing that serves as the main body of the lamp, the cross section is approximately hexagonal, designed to look good, and the length is compact enough to fit inside the inner hole of the annular fluorescent lamp A. Inside the casing 1, a lighting element 3 such as a ballast, a lighting tube, a switch, etc. is housed, leaving a space 2 at both ends.

4 is a support member made of an elastic metal wire;
The central part is folded in half and the bent part is slightly expanded laterally to form an annular fluorescent lamp support part 5 which is recessed in an arc shape in the vertical direction.
The supporting arm is expanded into a letter shape, and at both ends of the support arm, an insertion locking portion 7 bent into a rhombus shape and a straight stop portion 7a opposite to the neck portion of the locking portion 7 are formed by bending.

In the above configuration, two supporting members 4 are used,
When inserting and locking each insertion locking part 7 into the longitudinal hole 8 bored on both ends of the cylindrical casing 1, the support arm 6 is horizontally held at a predetermined angle with respect to the side surface of the cylindrical casing 1. The abutment part 7a resiliently abuts against the upper and lower outer surfaces of the vertically elongated hole 8 and is stabilized.

This invention constructed as described above has the following effects.

(1) Since the main components of the lamp are only the cylindrical casing and the support member made of two metal wires,
It has fewer parts than conventional lamps, and is not limited by the design of the lamp itself, making it simple and as small as possible at low cost. Everything can be stored, and the integrated packaging with the annular fluorescent lamp can be made compact, making it possible to significantly reduce physical costs, including packaging costs.

(2) When assembling the lamp, there are two
By simply inserting each insertion locking part of the book support member into the vertical hole a little forcefully, a solid connection between the cylindrical casing and the support member can be achieved, and both horizontal and vertical loads applied to the support member can be reduced. The support member does not wobble even when used, increasing stability, and no tools are required for assembly, making it extremely easy and reliable.

(3) During use, the arc-shaped recessed support portions formed on each of the two supporting members elastically contact the outer surface of the annular fluorescent lamp at two locations slightly apart in the circumferential direction of the annular fluorescent lamp, and the total It is supported at four points, and the cylindrical casing receives the load through the support members on both ends of the casing, which provides good balance when hanging the lamp and prevents the lamp from tilting. The annular fluorescent lamp remains stable in its fixed position unless a special external force is applied, and the contact between the supporting parts becomes a line contact, and the decrease in luminous flux due to the covering of the annular fluorescent lamp surface by the supporting part can be almost ignored. .

Claims (1)

[Scope of utility model registration request] A space is formed at both ends and a lighting element is placed inside.
It consists of a cylindrical casing with vertical holes on both sides of both ends and a metal wire long enough to fit into the inner hole of the ring-shaped fluorescent lamp, and the bent part is folded in half at the center and the bent part is placed on the side. The support arm of the annular fluorescent lamp is expanded slightly in the opposite direction and bent in an arc shape in the vertical direction to form a separate support part, and the diamond-shaped insertion and locking parts are inserted into both ends of the support arm which is expanded in a V-shape following the support part. The insertion locking portions of the two support members are inserted and locked into the corresponding vertical holes of the cylindrical casing, and the insertion locking portions of the two support members are inserted and locked into the corresponding vertical holes of the cylindrical casing. A fluorescent lamp device characterized in that the stop portions are brought into contact with the outer surface of the cylindrical casing at the upper and lower portions of the vertically elongated hole.
