The utility model is characterized in that both ends of a capacitor C are respectively connected with both ends of a filament A and a filament B; the capacitor C is arranged in the tube base 1; the both ends of the capacitor C are connected with two base pins of the tube base. The utility model can be cooperated with an electronic power supply of a high frequency non-hot filament, which is composed of a new non-hot filament high frequency electronic fluorescent lamp. The utility model has the advantages of long service life, small size, compactness, and convenient operation. The utility model enables no-load protection for power supplies.

Description

Non-hot filament fluorescent lamp tube

The utility model relates to lighting technology, and being specifically related to a kind of compact does not have the hot filament fluorescent tube.

Known electronic energy-saving lamp adopts high-frequency electronic power supply and compact energy-saving fluorescent tube, and filament all need heat during owing to starter and normal illumination, influences useful life, is difficult for applying.Provided a kind of novel electron fluorescent lamp among the prior art CN90221633.3, filament need not heat when starter and normal illumination, and obviously prolong useful life, but adopts known fluorescent tube structure, and the high-frequency electronic power supply might suffer damage when fluorescent tube opens circuit.

The purpose of this utility model is to design a kind of compact does not have the hot filament fluorescent tube, can carry out no-load protection to the high-frequency electronic power supply of novel electron fluorescent lamp.

Design of the present utility model is as follows: fluorescent tube comprises base 1, body 2 and adapter sleeve 3, an end a who it is characterized in that ends A 1, A2 and the capacitor C of body 2 filament A links, two ends B1, the B2 of body 2 filament B and the other end b of capacitor C link, capacitor C places in the base 1, A1, A2, a end link with the pin D1 of base 1, and B1, B2, b end link with the pin D2 of base 1.

Design of the present utility model can satisfy the requirement that the novel electron fluorescent lamp does not have hot filament; advantage with long service life; capacitor C places in the lamp socket; with the two ends of filament parallel connection at electronic power supply; when fluorescent tube does not link with power supply; power output end is open circuit, and circuit does not open and shakes, and power supply has been played the no-load protection effect.The utility model also has advantages such as volume is little, compact, easy to install.

The utility model has following accompanying drawing:

Fig. 2 compact does not have hot filament fluorescent tube structure schematic diagram

Fig. 3 H type does not have hot filament fluorescent tube schematic diagram

Fig. 4 triangle does not have hot filament fluorescent tube schematic diagram

Fig. 5 melon type does not have hot filament fluorescent tube schematic diagram

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model principle schematic, comprises that base 1, body 2 and adapter sleeve 3(are referring to Fig. 3, Fig. 4), body 2 inwalls scribble fluorescent material, and filament A, B are encapsulated in the body 2, draw through support A1, A2, B1, B2.One end a of ends A 1, A2 and the capacitor C of filament A links, and two ends B1, the B2 of filament B and the other end b of capacitor C link, and capacitor C places in the base 1.Like this, ends A 1, A2 and the B1 of filament A and B, B2 are respectively equipotential and connect, and all do not have the no hot filament of Joule heat when being formed on starter and normal illumination, have prolonged useful life greatly.The pin D1 of A1, A2, a three ends and base 1 links, and the pin D2 of B1, B2, b three ends and base 1 links the mode that connecting mode can adopt welding, clamping or weldering, card to combine.The output that pin D1, D2 and high frequency do not have a hot filament electronic power supply links and forms the complete high-frequency electronic fluorescent lamp of a cover.Because capacitor C and filament A, B two ends directly link; be integrated; when fluorescent tube does not link with power supply (the high-frequency electronic power supply is for unloaded); because power output end is open circuit; circuit does not open and shakes; can power supply be suffered damage, so the compact that the utility model provides have the no-load protection problem that the hot filament fluorescent tube has solved existing novel electron fluorescent lamp high frequency electronic power supply effectively.It is worthy of note; when fluorescent tube and power supply loose contact; press the scheme of fluorescent tube, capacitor C separate design, power supply also might suffer damage, but the fluorescent tube that integrated design mode of the present utility model causes this loose contact opens circuit and can play a protective role equally.

In the utility model, the filament of different capacity can be by the designing requirement apolegamy capacitor C of high-frequency electronic power supply.

Fig. 2 is the utility model structural representation, base 1 by plastics or similarly insulating material make, what shape can be with common energy-saving lamp is general, body 2 connects as one by adapter sleeve 3 with base 1, can adopt known method bonding, to guarantee enough intensity.

As a kind of embodiment, body 2 adopts H type (referring to Fig. 3); Adopt triangle (referring to Fig. 4) as another embodiment body 2.

Fig. 5 has provided a kind of embodiment of melon type body, and this shape helps overcoming the problem of stress concentration that body adds man-hour.

Because the utility model is no hot filament, so the diameter of filament can increase the service life more like this, the excursion of filament diameter can adopt known electricity-saving lamp 10W filament to ordinary straight spot 40W filament.
