Embodiment

As shown in Figure 1 and Figure 2, after the link of coil A, coil B added auxilliary amalgam 6, its port carries out hot working tack 3 to be handled, then that two coil closures are oppositely arranged side by side, on the distance position of lamp tube faced 310mm～150mm, after adopting two link glass-tubes that flame will be arranged side by side to punch, utilize the disjunctor behind its glass melting to carry out the connection of bridge joint 1.Should lead to gas when connecing bridge, it is unobstructed to guarantee that fluorescent tube connects the bridge opening 2 of bridge 1 part, and cooling back coil A and coil B cooperate other technological process to produce the bispin pipe and connect bridge interconnection system finished product fluorescent tube by connecing the tube cell that is coated with that bridge forms incorporate spiral fluorescent lamp.

Because the important photoelectric parameters such as operating voltage (light tube electric voltage) luminous efficiency of fluorescent lamp are all pressed in close relations with the interior mercury vapour of pipe, and the optimum value that mercury vapour is pressed in the pipe, the temperature that depends on fluorescent tube inner glass tube temperature lowest part (being commonly called as cold junction), therefore, the mercury vapour that the temperature of having controlled cold junction has just equaled to control in the fluorescent tube is pressed, adopt the glass-tube of tack to the bridge opening to make fluorescent tube cold junction 4, can solve the cold junction problem of coil well, can keep best cold junction temperature when making lamp works, to reach best operating state.In fluorescent tube, the effect of main amalgam is that mercury vapour is pressed in the control valve, makes it to make all the time in the high-temperature area of broad the balance mercury vapour to be pressed and is stabilized near the best residual gas pressure; And the effect of auxilliary amalgam is mercury atom " transfer house ", absorbs mercury atom during light-off, makes the equilibrium air pressure in the fluorescent tube very low, and after fluorescent tube opened jumping, auxilliary amalgam (during filament pre-heating) moment began to release mercury, and about 3min releases mercury and finishes.Pipeline is longer because the high-power spiral lamp tube caliber is thin, thereby luminous flux sets up slowlyer, in order to quicken the foundation of luminous flux, places the positive column 5 of bridge joint 1 position in and assists amalgam 6.Auxilliary amalgam 6 is connected with resilient seal wire 7, auxilliary amalgam 6 is placed in the positive column 5 above bridge opening 2, seal wire 7 utilizes its elasticity tension to be fixed on the inwall of cold-end glass pipe 4, after fluorescent tube opens jumping, the electric arc of positive column 5 (temperature is very high) heating is arranged on the auxilliary amalgam 6 of center, release mercury and need not wait the mercury atom at two ends to compile, can be simultaneously light in the center of coil, quickened the foundation of luminous flux effectively.Simultaneously, its port directly carried out the processing of hot working tack after spiral fluorescent tube can also adopt the link of a coil to add auxilliary amalgam, another coil link port directly carries out hot working tack and handles (Fig. 3), and other structure is the same with Fig. 1, Fig. 2.

Fig. 4, Fig. 5 are other methods of fixing auxilliary amalgam, as shown in Figure 4, after assisting amalgam 6 and seal wire 7 being connected, be placed in the link glass-tube of coil A and coil B, adopt the mode of hot working clamp 8, seal wire 7 and port 3 glass capsulations are fixed, auxilliary amalgam 6 is fixed in the positive column 5 above bridge opening 2.As shown in Figure 5, auxilliary amalgam 6 is connected on the support 10 of stem stem 9, puts in the glass tube of coil link, loudspeaker 11 carry out the hot working seal with the port of coil link.Simultaneously, cut envelope blast pipe 12, auxilliary amalgam 6 is fixed in the positive column 5 above bridge opening 2.

As shown in Figure 6, two coil volume ratios of high-power spiral formula fluorescent lamp are bigger, and two coils adopt the mode of bridge joint to be communicated with, and make two coils present one, and it connects bridge location and puts the comparison fragility, and when processing or installing and using, disrepair phenomenon appears in bridge location easily.With the mode of cold junction glass-tube and positive column glass-tube employing glue bond, reverse two pipes arranged side by side are carried out cementation, two pipe joint faces are increased, reduce the stress of its bridge joint position, avoided the bad phenomenon of bridge joint bit loss effectively.As shown in Figure 7, two coils connect into the ellipse fluorescent tube, can also be according to the use needs of various occasions, produce multiple other different shapes that bend.
