Abstract

A large power spiral fluorescence bulb. Two glass straight tubes are melted with hot work method and connected and fixed on the top position of the bulb, which is vertical to a spiral ring. Ends of two glass straight bulbs are separately sealed on two fixed electrode brackets with the electrode. Two input ends are separately sealed on two fixed electrode brackets with the electrode, so a bulb is equipped with a fixed electrode bracket with four electrodes and forms two independent discharge loop. Large power spiral fluorescence bulb made with other manufacture process can work with two electronic ballasts and ignite the large power bulb with low power ballast, which would also reduce a half time to build up luminous flux of bulb.

Description

Helical fluorescent lamp tube

Technical field

The utility model relates to compact fluorescent lamp tube, especially high-power spiral type fluorescent tube.

Background technology

Along with the growth of the anxiety and the environmental consciousness of international energy, especially helical type florescent lamp is because its light efficiency height for compact fluorescent lamp, and the visible light loss reduces, sound construction, and more compact advantage has become the main light source of room lighting.In order to enlarge range of application, with the helical type florescent lamp high-power, to replace the thermal light source of power consumption, to satisfy the wider application of lighting field, its market prospects are very tempting, but, in the structure of helical type florescent lamp, electric arc sets out with an electrode, rises in the mode of spiral, up to the top, then under the screw, fall in the coil of another spiral that the right opposite starting point differs 180 °, especially the high-power spiral lamp, its arc length is very long, thereby has influenced user's service quality.Simultaneously, because power is big, there is the deficiency of poor reliability in the integrated energy-saving lamp electronic ballast.

The utility model content

Exist luminous flux to set up difficult and have the reliability deficiency because of the electric ballast load is big in order to overcome the high-power spiral lamp, the utility model provides a kind of four fixed electrode supports that electrode is housed that have, article two, the high-power spiral type fluorescent tube of independent discharge channel, can adopt two electric ballasts to light a fluorescent tube, when improving the electric ballast reliability effectively, the time that the fluorescent tube luminous flux is set up shortens half.

The technical scheme that its technical problem that solves the utility model adopts is: with two glass straight tubes, by hot worked mode, being melt through is fastened on the tip position of fluorescent tube, in spiral coil.The port of two straight tube cells of glass respectively fixedly two of sealing-ins the fixed electrode support of electrode is housed, two inputs of fluorescent tube also respectively fixedly two of sealing-ins the fixed electrode support of electrode is housed, make a tubes have four fixed electrode supports that electrode is housed, and constitute two independently discharge channels.Reached the purpose of lighting the time of high-power fluorescent tube and the foundation of shortening fluorescent tube luminous flux with the small-power ballast.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the enlarged diagram of Fig. 1 embodiment junction.

Embodiment

As Fig. 1, shown in Figure 2, on the tip position 2 of high-power spiral lamp tube 1, pass through thermal processing method, glass straight tube 3 vertically is melt through on the one side 9 that is fastened on fluorescent tube tip position 2, glass straight tube 4 vertically is melt through on the another side 10 that is fastened on fluorescent tube tip position 2, two vertical glass straight tubes 3,4 caliber is φ 12～φ 20mm, drive retaining and be of a size of 5mm～30mm, by dusting, roasted tube, technologies such as crocus, the fixed electrode support 5 that has electrode, 6 are sealedly and fixedly connected respectively on two inputs, the fixed electrode support 7 that will have electrode, 8 difference sealing and fixing are at two vertical glass straight tubes 3,4 port, constitute and have four fixed electrode supports 5 that electrode is housed, 6,7, article 8 and two, independent discharge channel A, B manufactures high-power spiral type fluorescent tube by other manufacturing process.The caliber of fluorescent tube is φ 14～φ 26mm, and lamp power is at 65W～300W.The contact conductor of fixed electrode support 7 on straight tube 3 and fluorescent tube output fixed electrode support 5 connects one group of electric ballast, after the contact conductor of another output fixed electrode support 5 of fixed electrode support 8 on the straight tube 4 and fluorescent tube connects another group electric ballast and energized, make discharge channel A and discharge channel B carry out work respectively, whole tubes 1 is lighted, because a high-power spiral lamp is to adopt two ballasts, and each ballast only need be born half load of fluorescent tube, thereby the reliability and the useful life of having improved electric ballast effectively.Simultaneously, discharge channel A and discharge channel B are respectively half of helical lampl, shortened fluorescent tube discharge arc length, the time that makes fluorescent tube set up luminous flux has shortened half, produce owing to arc length is very long and set up luminous flux bad phenomenon slowly thereby solved the high-power spiral lamp, practicality is played very big facilitation.

Claims (1)

1. high-power spiral type fluorescent tube, it is characterized in that: two glass straight tubes are melt through to be connected on the tip position of fluorescent tube, in spiral coil, the port of two straight tube cells of glass respectively fixedly two of sealing-ins the fixed electrode support of electrode is housed, two inputs of fluorescent tube also respectively fixedly two of sealing-ins the fixed electrode support of electrode is housed, make a tubes have four fixed electrode supports that electrode is housed, and constitute two independently discharge channels, the caliber of fluorescent tube is φ 14～φ 26mm, the caliber of glass straight tube is φ 12～φ 20mm, drive retaining and be of a size of 5mm～30mm, lamp power is at 65W～300W.
