Abstract

The present invention relates to an electrode type fluorescent lamp which is composed of a light emitting member and a trigger, wherein the trigger is composed of a current limiter without an iron core, a capacitor and a diode; the light emitting member is only required to be provided with two electrodes and the shape of the light emitting member is arbitrary, can be designed according to aesthetics, which overcomes the defect that the light emitting member of the fluorescent lamp has to be a circular lamp tube in the traditional art. Because the current limiter is not provided with an iron core, materials are saved and cost is low. The performance of the trigger causes the lamp to light when power is switched on. Lamp light does not flash frequently, which is favorable to eyesight protection and causes the service life of a lamp fitting to be long. The trigger can be matched with a currently used fluorescent tube and replaces a ballast and a glow starter. Due to small volume, the trigger can be arranged in a socket or a power switch and thereby, a novel socket for fluorescent lamps and a power switch with the trigger are produced.

Description

Electrode type fluorescent lamp

The present invention is the electrode type allosome fluorescent lamp that integrates illumination and decorative effect, belongs to the electric light source field.

The lamp body of existing fluorescent lamp is made with glass tube, and two ends are respectively established one group of coiled-coil filament of reeling with tungsten filament in the pipe, every group of filament each with lamp holder on two lamp base conductings; Starter frequently dodged jumping when this fluorescent lamp had filament to switch on pre-thermal electron process, startup, it is quite big that the inductance coil that adds ballast does not have loss, and generation electromagnetic noise, especially starter is malfunctioning easily, be difficult to start when supply voltage or temperature reduction, fluorescent tube promptly lost efficacy after the open filament becomes waste product.

Existing cold-cathode fluorescence lamp illumination is very weak, and illuminating effect is too poor, still has to dodge phenomenon frequently, and low-voltage, the low more difficult startup of temperature can not be used for normal life, study and working place.

A kind of electrode type fluorescent lamp that Chinese patent 8720096 proposes still with existing " filament " fluorescent tube and inductance type ballast, changes little.

Task of the present invention is the structure of the existing fluorescent lamp of reform, fundamentally removes the above-mentioned shortcoming of existing fluorescent lighting fixture, have lamp body various shapes, economize on electricity significantly, useful life is quite long, integrates advantages such as illumination and decorative effect.

Technical scheme of the present invention is that this fluorescent lamp is made of electrode, lamp body, lamp holder (or lamp socket) and lamp base, and two electrodes replace two groups of filament, and the space separately is arranged in the lamp body, and lamp body is made various allosome moulding with composite polymer material or glass; Electrode is led metal material or low electricity with high electricity and is led nonmetallic materials and make the shape that cooperates with the moulding of lamp body section; Lamp holder (seat) is made with macromolecular material and is covered shape or box-like; Two lamp bases that link to each other with electrode can be with end or heterodoxy setting;

Electrode face of the present invention is provided with tip or salient point; The shape of electrode and structure are tabular, sheet, netted, radial, any shape of helicoid shape or their combination shape.

It is one of chromium, nickel, tungsten, stainless steel that the used high electricity of kind electrode is led metal material.Or use their alloy materials; Also can be any of lining chromium on iron-based or the copper base electrode, nickel, tungsten, the alloy material of perhaps using them be as coating; In addition, analyse (sheet) shape electrode and can lead any manufacturing of nonmetallic materials graphite, carbon, carborundum, molybdenum carbide, perhaps use their mixture manufacturing with low electricity; Add high electricity in also can be in any of above-mentioned nonmetallic materials and composition thereof and lead metal dust.

Because filament is used electrode instead, there is not the energising warm, thereby electrode has will consider the definite value of filament resistance and the definite value of preheat curent as filament, and the length and the diameter of filament are limited, make it to turn to the such solid shape of single helicoid, so lamp body also can only be made a kind of shape, the preheating and electrode need not switched on, can not be subjected to resistance, electric current, length, the restriction of diameter, so can make arbitrary shape, just making various moulding for lamp body has created prerequisite for this, this is that existing filament fluorescent lamp can not be realized, hence one can see that with behind the electrode replacement filament, broken through at one stroke on the history of fluorescent lamp manufacturing in the past and can only make the traditional structure of tubular, thereby made fluorescent lamp enter the update condition.

Further set forth technical scheme of the present invention and embodiment below in conjunction with accompanying drawing:

Fig. 1 is electrode type allosome fluorescent lamp schematic diagram (for convenience of explanation, still using the circular straighttube lamp body among the figure);

Fig. 2-1～Fig. 2-the 9th, electrode type allosome fluorescence lamp body base shape figure;

Fig. 3-1～3-10 is electrode type allosome fluorescent lamp electrode structure base shape figure;

Fig. 4-1～4-4 is electrode type allosome fluorescent lamp lamp holder, lamp base base shape figure;

In Fig. 1, electrode (12) is contained in two ends in the lamp body (11), each electrode by lead-in wire (33) by lamp base (14) conducting on airtight lamp body end socket and the lamp holder (13); Lamp base is distributed in heterodoxy (Fig. 1-1) and also can be distributed in end (Fig. 1-2).

The lamp body of Fig. 2 (11) is made with transparent material, comprise with transparent composite polymer material or glass, its shape and structure can require any moulding according to industrial art, for example: Fig. 2-1 is a flat bar, and Fig. 2-2 is a deltiod, and Fig. 2-3 is oblate, Fig. 2-4 is a long ball shape, Fig. 2-5 is a spheroidal, and Fig. 2-6 is the incandescent lamp alveolitoid, and Fig. 2-7,2-8,2-9 are three kinds of wall lamp shape lamp bodies.

Fig. 3 is the basic structure of electrode, for example: and Fig. 3-the 1st, with hanging down the platy structure that electricity is led nonmetallic materials system; Fig. 3-the 2nd leads the laminated structure of metal material system with high electricity; Fig. 3-the 3rd, netted a kind of structure; Fig. 3-the 4th is with " Y " shape helicoid electrode of 2 circle annular brace muscle (39); Fig. 3-the 5th, " O " shape helicoid of band radiation tendon; Fig. 3-6～Fig. 3-9 is four kinds of nets and spirochetal combination, Fig. 3-the 6th wherein, the dome electrode of up-small and down-big pairing, the sphere direction is downwards consistent, bottom electrode central tap (33) passes through in the polar net hole after passing insulating sleeve (40) from power on, and kind electrode is suitable for the incandescent lamp bulb shape lamp body of Fig. 2-6 supporting; Fig. 3-7 is two a pair of hemisphere face electrodes that diameter is identical, sphere is arranged dorsad, is suitable for the spherical or cylindrical lamp body of Fig. 2-4, Fig. 2-5 supporting; Fig. 3-the 8th, a pair of semicircle (or claiming fan-like pattern) electrode is suitable for the half-cylindrical lamp body of Fig. 2-7 supporting; Fig. 3-the 9th, a pair of rectangular electrode is suitable for the lamp body of Fig. 2-1, Fig. 2-2, Fig. 2-8 supporting; Fig. 3-the 10th, inner small and outside big ring-band shape electrode also can be made the shaped as frame band shape, and is supporting with the lamp body of Fig. 2-3, Fig. 2-2 respectively.
