Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a fluorescent lamp device, and is particularly applicable to a table lamp, etc., in which the direction of the luminous tube can be freely changed. It relates to a light lamp device.

(Prior Art) So-called compact fluorescent lamps are compact fluorescent lamps that are characterized by high brightness, and are widely used for interior lighting, table lamps, and the like. In general, this kind of compact fluorescent lamp is made by bending a thin-diameter arc tube into a U-shape or M-shape, and is often of the type with a cap on one side.

In addition, recently, this compact fluorescent lamp has been applied to highly interior circular lighting fixtures such as floor stands and table lamps, so the tube wall load has increased to 80■ν.
/C- or higher ring types are also being considered. When this ring-shaped compact fluorescent lamp is used as a floor stand or table lamp, high-intensity illumination can be achieved with a relatively compact device.

By the way, there are times when it is desired to adjust the lighting in a room or on a desk where the above-mentioned lighting equipment is used, or to change the lighting angle for an interior effect. In such a case,
Previously, this was dealt with by changing the direction of the lighting fixture's shade or reflective umbrella.

(Problem to be Solved by the Invention) However, as with the above-mentioned lighting equipment, it is almost impossible to change the light distribution by changing the direction of the shade or reflective umbrella. The problem is that we have to change.

In addition, in the conventional method of attaching a socket to the cap of an arc tube, the cap pins face the inner surface of the lamp, which has a narrow inner diameter, making it difficult to work. There is also a risk that stress will be concentrated on the holding portion and the arc tube will be damaged.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technology, to easily change the direction of the arc tube attached to the lighting equipment, and to have a high degree of freedom when designing the lighting equipment. An object of the present invention is to provide a fluorescent lamp device.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention connects a fitting to a base formed on an arc tube, and has a fitting part with the fitting to make the arc tube The present invention is characterized in that it includes a holder that slidably supports the arc tube, and a lead wire of the arc tube is led out through the fitting into the holder.

(Function) According to the present invention, a fitting is connected to a cap formed on an arc tube, and a holder is provided which has a fitting portion with the fitting and slidably supports the arc tube, Since the lead wire of the arc tube is guided into the holder through the fitting, the direction of the arc tube can be freely changed by the fitting so as to maintain a predetermined angle with respect to the holder.

(Embodiment) An embodiment of the fluorescent lamp device according to the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 1, reference numeral 1 indicates an arc tube of a fluorescent lamp device. The arc tube 1 shown in this embodiment has a tube diameter d - 17.5 mm and a ring center line diameter - 140.5 mm, and is an annular compact type that can secure a tube wall load of about 801/cj or more. It is a fluorescent lamp.

A cap 2 is attached to the arc tube 1 so as to cover the stem 1a at both ends thereof. The cap 2 has a substantially cylindrical shape with a curvature almost equal to that of the arc tube 1, and is formed into a mating shape of half halves consisting of an upper cap 2A and a lower cap 2B.

Further, a cylindrical neck portion 3 is connected to a substantially central position of the lower base 2B, and a substantially spherical fitting 4 is fixed to the lower end of this neck portion 3. This fitting element 4 is fitted into a recess 5a provided at the upper part of a substantially square pyramidal truncated holder 5, so that the holder 5 can support the arc tube 1.

The holder 5 has a half-split structure so as to be able to hold the fitting 4, and has a built-in predetermined weight to prevent it from falling over even when the arc tube 1 is supported through the fitting 4.

Furthermore, since the fitting 4 is slidably fitted into the recess 5a, the direction of the arc tube 1 can be changed by appropriately rotating the fitting 4. At this time, the sliding resistance of the fitting portion is set to a certain degree so that the arc tube 1 does not slide unless an external force is applied to move the arc tube 1 . Therefore, the fitting element 4 does not rotate and fall down due to the weight of the arc tube 1.

Next, the structure of this fitting element 4 will be explained in detail with reference to FIGS. 2 to 4.

FIG. 2 shows a state in which the fitting 4 attached to the arc tube 1 is removed from the holder 5. Outer wires 6 (lead wires) attached to both ends of the arc tube 1 extend from the base 2 through the neck 3 to the opening 4a at the lower end of the fitting 4. This outer wire 6 is wired with a predetermined margin length so that it will not break even if the mating element 4 rotates by an arbitrary angle, and its end is connected to the connection terminal 7 in the holder 5. It is connected.

FIG. 3 shows the fitting 4 in this embodiment, and the two-dot chain line shows the stem 1a at the end of the arc tube 1. A cap 2 is attached to cover the stem 1a,
This cap 2 has a substantially cylindrical shape having a curvature almost equal to that of the arc tube 1, and has a half-split shape consisting of an upper cap 2A and a lower cap 2B. A circular hole 8 is provided at approximately the center of the lower base 2, and the cylindrical neck portion 3 is fitted into the circular hole 8. As shown in FIG. 4, this neck portion 3 has four small diameter cylinders 9 fixed therein. This small diameter cylinder 9 serves as a separator to prevent the outer wires 6 from coming into contact with each other, and four outer wires 6 can be inserted into each cylinder. This separator is not limited to the above-mentioned cylindrical shape, for example, a cross-shaped partition plate may be attached, and the outer wire 6
may be covered with vinyl.

Further, a substantially spherical fitting 4 is fixed to the lower end of the neck 3. A cylindrical hole 4b that communicates with the neck portion 3 is bored almost to the center of the fitting 4, and a semi-cylindrical notch is provided in the lower half of the fitting 4 to connect with the hole 4b. It is provided. Thereby, the outer wire 6 of the arc tube 1 can be extended to the outside from the notch of the fitting 4.

Next, as another embodiment, an example in which this fluorescent lamp device is applied to a flat type compact fluorescent lamp will be described.

In Fig. 5, the arc tube 1 of the compact fluorescent lamp
A base 2 made of PBT resin is formed on the base 2, and a fitting 4 is connected to the lower end of the base 2 via a neck 3. Furthermore, this fitting element 4 is fitted into the upper four parts 5a of the holder 5 which is substantially a truncated square pyramid. A cavity 5b is formed inside the holder 5, and a lighting tube 11 and a ballast 12 are provided inside the cavity 5b. An outer wire 6 is led out into the cavity 5b to connect the lighting tube length 11 and ballast 12 to the arc tube 1. The lighting tube 11, the ballast 12, and the arc tube l are connected to the connection terminal 7.
It is now possible to connect via. If such a fluorescent lamp device is used as a desk lamp, the direction of the compact fluorescent lamp can be freely changed to suitably set the illumination range on the desk.

In addition, as shown in FIG. 6, as another embodiment, the starting element 13 such as a lighting tube or a capacitor can be accommodated in the base 2 made of PBT resin. In this case, the starting element should be fixed at a predetermined position within the cap 2 to prevent the lead wire 14 from breaking internally when the arc tube 1 is moved, or the starting element 13 from being damaged by impact. is desirable. Furthermore, in order to facilitate the connection between the fixed starting element 13 and the arc tube 1, a terminal clip 15 made of a conductive material as shown in FIG. 7(a) can be used. This terminal clip 15 is made of a plate spring material, and can hold the lead wire 14 of the starting element 13 and the outer wire 6 of the arc tube 1 at its tip 15a.

Then, as shown in FIG. 7(b), the wire is inserted into the recess 2a provided in a part of the base 2 while the wire is being held, and the wire is connected. Thereby, the lead wire of the starting element 13 and the outer wire 6 of the arc tube 1 can be reliably connected within the base 2.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since the arc tube is supported by a holder using a slidable fitting, the direction of the arc tube can be changed freely, and the lighting equipment This has the effect of increasing the degree of freedom in design.
