Description

Compact fluorescent lamps {COMPACT FLUORESCENT LAMP}

The present invention relates to a compact fluorescent lamp, more specifically, to form a semi-circular length screw groove on the inner periphery of the lower case, and to form a semi-circular length thread on the outer periphery of the upper case so that they can be assembled together. At the same time, the coupling pieces of the upper case can be fitted into the seating holes of the lower case to prevent the twisting of the cable, which may occur when the upper case is rotatably assembled to the lower case. The present invention relates to a compact fluorescent lamp that can be worked very conveniently when dismantling from a case.

In general, a fluorescent lamp is a discharge lamp that emits light by converting ultraviolet rays emitted by a low-pressure mercury discharge into visible light by a phosphor, and recently, a light emitting part including a base is a fluorescent lamp, and a ballast or a lighting device Some, including lamps, may be distinguished by fluorescent lamps.

The fluorescent lamp stabilizes the current by using a stabilizer such as choke coil in order to lower the current to a specific value since the current of the lamp may continuously increase when the discharge phenomenon starts. In many cases, a lamp is used for lighting, and a lamp that is turned on is also called a starter fluorescent lamp.

When a voltage is applied by the power switch, a glow discharge occurs between the bimetal electrode and the fixed electrode of the glow starter, and by this discharge, the bimetal electrode is heated to contact the fixed electrode.

At this time, electric current flows to the filament electrode of the fluorescent lamp and is heated to a temperature where it is easy to emit hot electrons. During this time, the bimetal electrode cools down and after a few seconds, the pulse voltage is generated by the inductance of the ballast, and the hot electrons are generated at the filament electrode. At the same time, the fluorescent lamp is activated and the arc discharge occurs.

Thereafter, the ultraviolet radiation radiated by the arc discharge in the low pressure mercury vapor excites the phosphors and radiates visible light to brighten the surroundings.

Such fluorescent lamps are more efficient than incandescent bulbs, consume only 1/3 to 1/4 of the power consumption, have the advantage of soft light and low radiant heat, and have a lifespan of 5 to 10 times (5000 to 10,000 hours) compared to array bulbs. Long enough.

Recently, compact fluorescent lamps have been used for forming discharge electrodes on both ends of a bulb coated with a fluorescent material on the inner surface and injecting mercury vapor and ash gas into a vacuum bulb.

The object of the present invention is to form a semicircular length screw groove on the inner circumference of the lower case and to form a thread of a semicircular length on the outer circumference of the upper case so that they can be assembled in a mutually screw type, and at the same time, the coupling pieces of the upper case The present invention provides a compact fluorescent lamp that can be easily disassembled by being fitted into a seating hole of a case.

Hereinafter, a preferred embodiment of the compact fluorescent lamp according to the present invention will be described with reference to FIGS. 1 and 2.

1 is a perspective view showing a compact fluorescent lamp according to the present invention, Figure 2 is a cross-sectional view of the main portion showing a compact fluorescent lamp according to the present invention.

As shown in FIGS. 1 and 2, the compact fluorescent lamp 100 according to the present invention typically forms discharge electrodes (discharge filaments) 111 at both ends of the bulb 110 coated with a fluorescent material on an inner surface thereof, and is in a vacuum state. Inject the mercury vapor and ash gas into the bulb 110 of the used.

When a high-voltage current is applied to the discharge electrodes 111 provided at both ends of the bulb 110, a flow of electron beams is formed in the bulb 110 according to the discharge current, and the ultraviolet rays emitted by collision of the electron beam with mercury vapor are emitted. The fluorescent material applied to the inner surface of the bulb 110 is excited to emit visible light to emit light. That is, the hot electrons emitted from the discharge electrode 111 collide with the mercury atom to cause ionization or excitation to become an arc discharge, and when the excited mercury atom returns to its original low energy level, ultraviolet rays are generated and visible light is emitted by the fluorescent material. By converting to the light can be emitted.

Such a compact fluorescent lamp 100 is a lamp used by merging into an existing incandescent lamp socket. When using a three-wavelength fluorescent material, the compact fluorescent lamp 100 protects eyesight by the reproduction of light close to a natural color and saves 70 to 80% of the power saving effect compared to an incandescent lamp. Of course, it is very popular because of its high price performance, which is more than 8 times the lifetime.

On the other hand, the bulb 110 is a kind of vacuum tube is coated with a fluorescent material on the inner surface and the discharge electrode 111, which is mainly referred to as a discharge filament at both ends is provided, the upper case (approximately inverse alphabet (유) shape or spiral, etc.) It is fitted into the support hole 121 of the 120.

The upper case 120 may be attached to or detached from the lower case 130 in which a plurality of circuit components, that is, a circuit board (eg, a lighting controller 140) that converts and supplies power supplied from outside into a stable current and supplies the same. To be assembled, the subject innovation is the assembly structure of the upper case 120 and the lower case 130 is the core.

Herein, a general assembly structure of the compact fluorescent lamp 100 and a structure according to the present invention will be described with reference to FIG. 3 as follows.

Figure 3a is an exploded perspective view showing a typical compact fluorescent lamp, Figure 3b is an exploded perspective view showing a compact fluorescent lamp according to the present invention.

As shown in FIG. 3A, the general compact fluorescent lamp 100 forms a rounding groove 2 on the inner circumference of the lower case 130, and forms a rounding jaw 1 on the outer circumference of the upper case 120. By pressing the upper case 120 while pressing the lower case 130 is configured to achieve a close coupling with each other.

At this time, the reason for assembling the upper case 120 to the lower case 130 is because of the structure of the lighting control unit 140 is connected to the discharge electrode 111 and the cable 150 inside the lower case 130. When assembling in a screw-type rotary type, connection abnormality occurs due to the twisting of the cable 150, etc., thus taking a press-fit assembly structure in a linear direction.

By the way, the upper case 120 and the lower case 130 of the compact fluorescent lamp 100 according to the prior art as described above, the rounding jaw 1 of the upper case 120 is a lower case 130 by mutual indentation operation. It can be easily coupled to the rounding groove (2) of the assembly is acceptable, but when the abnormality of the lighting control unit 140 provided in the lower case 130 or the life of the bulb 110 is to be replaced In this case, the disassembly work between each other is very difficult, which is pointed out as an uncomfortable disadvantage.

That is, the upper case 120 can be closely assembled to the inner circumference of the lower case 130, so that the mutual coupling force is good, but in the reverse case, the upper case 120 is separated from the inner circumference of the lower case 130. When the force is applied so as to move away from the rounding groove 2, the rounding jaw 1 must be sufficiently spaced apart so that disassembly can be achieved, and a momentary impact is applied in the process of removing the upper case 120 from the lower case 130. The big disadvantage that the breakage or adverse effect of the lighting control unit 140 occurred.

Therefore, the present invention may occur when the upper case 120 is assembled in a screw-type rotation type in the structure of the lighting control unit 140 connected to the discharge electrode 111 and the cable 150 in the lower case 130. Understand the difficult disassembly work when assembled by conventional press-fitting while taking into account the twisting of the cable 150, and assembling the upper case 120 to the lower case 130 by a semi-rotating screw type and close mutually It is to propose a structure provided with a coupling piece 123 to be assembled.

That is, as shown in FIG. 3b, the compact fluorescent lamp 100 according to the present invention forms a threaded groove 131 having a semicircular length at the inner circumference of the lower case 130, and the outer circumference of the upper case 120. To form a thread (122) of semi-circular arc length is configured to be assembled to each other screw type.

In this case, assembling the upper case 120 to the lower case 130 by a 180 ° rotation radius is the cable 150 for connecting the discharge electrode 111 and the lighting control unit 140 provided at both ends of the bulb 110. It is possible by the allowance of, and further rotation is limited because the twisting of the cable 150 occurs.

4 is a cross-sectional view for explaining a compact fluorescent lamp according to the present invention.

Since the 180 ° rotational coupling of the upper case 120 and the lower case 130 can be easily disassembled by external shaking, the rotational direction at the bottom of the upper case 120 as shown in FIG. Partially cut to exert an elastic force and further form a coupling piece 123 having a coupling jaw 123a protruding outward, and the upper case 120 is the 180 ° rotational coupling is completed to the lower case 130 The bottom case 130 of the through-molded seating hole 132 for receiving the engaging jaw (123a) of the coupling piece 123.

At the point where the upper case 120 is rotated 180 ° to be precisely coupled to the lower case 130, the coupling jaw 123a of the coupling piece 123 is elastically fitted to the seating hole 132 of the lower case 130. The close coupling is achieved, and thus, even when an external shock or shaking occurs, the coupling state can be firmly maintained without being separated.

On the other hand, when the life of the bulb 110 is to be replaced or when repair is required beyond the lighting control unit 140 built in the lower case 130, the coupling jaw 123a exposed to the seating hole 132 is removed. Lightly pushed using a sharp tool to allow the engaging piece 123 to be separated from the seating hole 132 and at the same time reverse rotation of the upper case 120 can be naturally disassembled.

The detachable coupling structure of the upper case 120 and the lower case 130 of the compact fluorescent lamp 100 does not require excessive force in the production of the first product, thereby minimizing the defective rate during the assembly process. When replacement or replacement of the lighting control unit 140 is required and the disassembly is required, it is possible to realize a very natural disassembly operation due to reverse rotation, and thus it can be seen that the benefit of use is further amplified.

As described above, according to the compact fluorescent lamp 100 according to the present invention, a semicircular arc-shaped screw groove 131 is formed on the inner circumference of the lower case 130 and the semicircular arc length is formed on the outer circumference of the upper case 120. The upper case by forming a screw thread 122 of the upper case 120 so as to be assembled in a mutually screwed manner and at the same time can be fitted to the seating hole 132 of the lower case 130. It is possible to prevent the twisting of the cable 150, which may occur when the assembly 120 to the lower case 130 to rotate in advance, and very if you want to disassemble the upper case 120 from the lower case 130 There is an advantage to working conveniently.

That is, the upper case 120 and the lower case 130 can be coupled to rotate 180 ° of the lighting control unit 140 is connected to the discharge electrode 111 and the cable 150 inside the lower case 130. Structural structure can overcome the twisting of the cable 150 that may occur when the upper case 120 is rotated by more than 360 °, the upper case 120 is rotated 180 ° to be accurately coupled to the lower case 130 At this point, the coupling jaw 123a of the coupling piece 123 is elastically fitted to the seating hole 132 of the lower case 130 to form a close coupling structure with each other, so that even when an external shock or shake occurs, There is a usefulness that can maintain the state of the bond firmly.

On the other hand, when the life of the bulb 110 is to be replaced or when repair is required beyond the lighting control unit 140 built in the lower case 130, the coupling jaw 123a exposed to the seating hole 132 is removed. Lightly pushed using a sharp tool to allow the coupling piece 123 to be separated from the seating hole 132 and at the same time reverse rotation of the upper case 120 has the convenience of disassembly that can be naturally disassembled.
