Description

A kind of helical fluorescent lamp tube

Technical field

The utility model relates to a kind of helical fluorescent lamp tube.

Background technology

Compact fluorescent lamp is since the eighties in 20th century invention, because its light efficiency height, life-span length, compact conformation, characteristics such as energy-conservation are widelyd popularize.Especially helical fluorescent lamp tube because structure is more compact, firm, optical loss reduces and good advantages such as distribution curve flux distribution, becomes one of main light source of indoor and outdoor lighting especially.But because compact conformation, lamp current density is risen, thereby electron density is risen, cause the pipe temperature to rise, mercury vapour in the fluorescent tube is pressed the optimal values that has departed from cold junction, makes lamp power and lumen that obvious decline all be arranged, and especially works in totally enclosed lampshade, its lamp power and lumen descend severely more, reach more than 20%.Simultaneously, in the structure of helical type florescent lamp, electric arc sets out with an electrode, rises in a spiral manner, up to the top, then under the screw.Fall in the coil of another spiral that faces 180 ° of starting point phase phasic differences, arc length is very long, thereby has influenced the rapid foundation of luminous flux.Influence the problem that luminous flux is set up rapidly because helical type florescent lamp fails to solve well cold junction temperature and electric arc is long, thereby limited it in the wider application of lighting field.

The utility model content

The purpose of this utility model is to provide a kind of and sets up the helical fluorescent lamp tube that a band is assisted amalgam interconnection system cold junction in helical fluorescent lamp tube tip position scope, makes the foundation of fluorescent tube take-off post acceleration fluorescent tube luminous flux and makes the fluorescent tube cold junction temperature be controlled at optimum state after the fluorescent tube operate as normal.

The purpose of this utility model can realize by following technical measures: at the top of helical fluorescent lamp tube 12 position ranges, connect a glass tube, become interconnection system cold junction 3.One end of this cold junction 3 is communicated with top 2, and the glass tube of the auxilliary amalgam 6 that will be connected with seal wire 8 by cold junction 3 is placed in the fluorescent tube at fluorescent tube top 2,8 of seal wires that auxilliary amalgam 6 connects are done the sealing processing with the glass tube other end 5 of cold junction 3 then near fixing effect in cold junction 3 glass tubes.Constituting the diameter of interconnection system cold junction 3 glass tubes, the length of length of tube, is that shape and the power according to fluorescent tube decides.The utility model compared with prior art has the following advantages: heating when the electric arc (temperature is very high) of positive column after the fluorescent tube take-off is arranged on auxilliary amalgam 6 in the pipe of fluorescent lamp 1 top 2, releasing mercury need not wait the mercury atom at two ends to compile, fluorescent lamp 1 top 2 can be simultaneously light, can more promptly set up luminous flux, thereby avoid existing helical fluorescent lamp tube luminous flux to set up slower phenomenon.Simultaneously, because the important electrical quantitys such as operating voltage (light tube electric voltage) luminous efficiency of fluorescent lamp, all press in close relations with the interior mercury vapour of pipe, and the occurrence 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 temperature of control cold junction has just equaled to control the mercury vapour pressure in the fluorescent tube.For helical fluorescent lamp tube, often mercury vapour is pressed too high and light efficiency is significantly descended, the setting of the fluorescent tube cold junction of current technology, just optionally at the top or the negative electrode position be provided with, thereby cause lamp power and lumen temperature influence and the bad phenomenon that descends.And be provided with a cold junction artificially, difformity and different capacity according to helical type florescent lamp, the glass tube of cold junction adopts the design of different tube diameters and different length, make the cold-end glass in the fluorescent tube be controlled at best state of temperature, thereby the mercury vapour of having controlled in the fluorescent tube is pressed, and reaching best operating state, and can be acted upon by temperature changes lessly, thereby guaranteed the consistency of lamp power and light efficiency effectively, to satisfy the instructions for use of practical application.

Description of drawings

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

Fig. 1 is the structural representation of the helical fluorescent lamp tube of the auxilliary amalgam interconnection system cold junction of band.

Fig. 2 is the A expanded view in the structural representation of the helical fluorescent lamp tube of the auxilliary amalgam interconnection system cold junction of band.

Embodiment

As shown in Figure 1, an end of cold junction 3 glass tubes is placed on top 2 position ranges of helical fluorescent lamp tube 1, is connected, should guarantee during connection that the glass tube of cold junction 3 and fluorescent tube 1 are unimpeded after 4 punchings of fluorescent tube connecting portion cold junction pipe 3 being sealed with fluorescent tube 1.

Fig. 2 is the expanded view of A among Fig. 1.With after seal wire 8 is connected, auxilliary amalgam 6 is placed in the fluorescent tube at top 2 of helical fluorescent lamp tube 1 auxilliary amalgam 6 by junction 7, and seal wire 8 is placed in the glass tube of interconnection system cold junction 3, is used for fixing to assist amalgam 6.The other end 5 of interconnection system cold junction 3 glass tubes seals processing.Since the important photoelectric parameters such as operating voltage (light tube electric voltage) luminous efficiency of fluorescent lamp all with pipe in mercury vapour press in close relationsly, and the optimum value that mercury vapour is pressed in the pipe depends on that fluorescent tube controlled the interior mercury vapour pressure of fluorescent tube.And the glass tube of interconnection system cold junction 3 not only is placed at the top of helical fluorescent lamp tube 12 position ranges, and be the centre position that is placed on fluorescent tube, like this, no matter be that the ambient temperature used of fluorescent tube self temperature or fluorescent tube is little relatively to the variation of cold junction temperature, thereby guaranteed the temperature of cold junction, also guaranteed that the mercury vapour in the fluorescent tube presses optimum value, thereby solved because cold junction temperature changes the lamp power that causes and the existing problems of electric current decline.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 balance mercury vapour in the fluorescent tube press very low.After fluorescent tube opens jumping, the electric arc of positive column (temperature is very high) is heated and is arranged on the interior auxilliary amalgam 6 of helical type florescent lamp 1 top, 2 pipes, release mercury and need not wait the mercury atom at two ends to compile, the top 2 of helical type florescent lamp 1 can be simultaneously light, thereby quickened the foundation of helical type florescent lamp luminous flux.
