DISCHARGE TUBE DEFORMITY PREVENTION STRUCTURE FOR ELECTRIC BULB TYPE FLUORESCENT LAMP}

The present invention relates to a structure for preventing deformation of a discharge tube of a fluorescent lamp, and more particularly, a phenomenon in which a discharge tube, which is installed in the fluorescent lamp, is deformed due to contraction or expansion due to heat change or twisting occurs. It is basically to prevent.

In general, bulb fluorescent lamps are used in a variety of applications, from home or office lighting to street lamps, security lamps and monument lights, which are compared to incandescent bulbs, sodium bulbs, halogen bulbs and metal bulbs. Although there is no significant difference, the power consumption is low, the service life of the lamp is long, and since the electronic ballast is built in the fluorescent lamp, it is possible to turn on instantaneously and there is no flicker like a conventional fluorescent lamp. It is being replaced by fluorescent lamps.

Meanwhile, in the case of the conventional fluorescent lamp 1, as shown in FIG. 1, the discharge tube 3 is prevented from being deformed as the discharge tube 3 continues to expand and contract by repeated lighting and turning off. For this purpose, the deformation of the discharge tube 3 is suppressed by adhering between the discharge tube 3 and the discharge tube 3 with a cement bond 4 or the like.

That is, since the heat is generated in the discharge tube 3 while the above-described fluorescent lamp 1 is turned on, the discharge tube 3 is expanded, and heat is discharged to the discharge tube 3 while the fluorescent lamp 1 is turned off. Since it does not occur, the expansion and contraction process such as the discharge tube 3 contracts is repeated.

As such, when the discharge tube 3 of the fluorescent lamp is expanded or contracted, the discharge tube 3 may be loosened from the fixed holder 2 or may be deformed, causing a failure of the bulb fluorescent lamp. .

Therefore, in order to prevent this, the conventional bulb-type fluorescent lamp 1 was manufactured by bonding a cement bond 4 between the lower end and the upper end between the discharge tube 3 and the discharge tube 3 with a cement bond 4, but the period of use has elapsed. As a result of the expansion or contraction caused by the thermal change of the discharge tube 3, cracks are generated at the bonding part 4 or the bonding part is dropped, resulting in a decrease in the service life of the fluorescent lamp. There is a problem such as ultimately lowering the efficiency and reliability of the fluorescent lamp (1).

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the discharge tube installed in the bulb-type fluorescent lamp is a phenomenon that the deformation occurs such as the opening or contraction, such as twisting or expansion due to thermal changes It is an object of the present invention to provide a discharge tube deformation preventing structure of a fluorescent lamp of the bulb type, which can be fundamentally prevented to improve the service life of the fluorescent lamp.

In order to achieve the above object, the present invention has a fixing means for tightly fixing the inner circumferential surface, such as the shape of each discharge tube, on the inner circumferential surface of the upper end portion between the plurality of U-shaped discharge tubes fastened to the fixed holder of the fluorescent lamp. A discharge tube deformation preventing structure of a bulb type fluorescent lamp is provided.

In addition, a plurality of first fixing members, which are the fixing means, are inserted into the inner circumferential surface of the upper end portion between the discharge tube and the discharge tube, and are formed on both sides to surround each of the inner circumferential surfaces of the discharge tube, respectively, and are formed between the fixing pieces, the discharge tube and the discharge tube. Characterized in that it is composed of a connecting piece inserted between.

The second fixing member, which is the fixing means, is inserted into the entire inner peripheral surface of the upper end portion between the plurality of discharge tubes fastened to the fixing holder, and a hollow insertion portion formed in the center portion for insertion into the entire inner surface between the other end portions of the discharge tube; It is formed so as to branch to each corner of the insertion portion is characterized in that composed of a support piece for wrapping the inner peripheral surface of the upper end of each discharge tube.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

Figure 2 is a perspective view showing a fluorescent lamp of the first and second fixing member is inserted, respectively, according to the present invention, Figure 3 is a plan view of Figure 2, Figure 4 is a first and second fixing member according to the present invention Each is a perspective view shown.

The present invention is inserted into the lower end of the plurality of discharge tube 30 of the U-shape into the fixed holder 20 of the bulb-type fluorescent lamp 10 is bonded by an adhesive or the like, between the discharge tube 30 and the discharge tube 30 A fixing means made of a heat-treated stainless material is inserted into the upper end inner circumferential surface in order to closely fix the inner circumferential surface of each discharge tube 30.

The first fixing member 40, which is the fixing means, is inserted into a plurality of inner peripheral surfaces of the upper end portion between the discharge tube 30 and the discharge tube 30, and fixing pieces 42 formed on both sides to surround the inner peripheral surface of each discharge tube 30, respectively. ) 44 and a connecting piece 46 formed between the fixing pieces 42 and 44 and inserted between the discharge tube 30 and the discharge tube 30.

The second fixing member 50, which is the fixing means, is inserted into the entire inner circumferential surface of the upper end between the plurality of discharge tubes 30 installed in the fixing holder 20, and is inserted into the entire inner surface between the upper ends of the discharge tube 30. It is formed by the hollow insertion part 52 formed, and the support piece 54 which is formed so that it may branch to each corner part of this insertion part 52, and surrounds the inner peripheral surface of each discharge tube 30.
