Description

Glow starter

Technical field

The utility model relates to lighting technology, particularly a kind of fluorescent lamp starting device.

Background technology

There is the heating tungsten filament at the two ends of the fluorescent lamp that uses at present, and when the tungsten filament fusing of an end, fluorescent tube does not just work.At this defective, a solution has appearred, promptly use lead in pin outside short circuit at an end of tungsten filament fusing, make circuit become the loop, the tungsten filament of an end of fusing can not continue heating, fluorescent tube is lighted, but starting time is long, and if after the fusing of other end tungsten filament, fluorescent tube can not be used again, this technology trends that will be unfavorable for saving use cost and energy-conserving and environment-protective is inconsistent.

Summary of the invention

The purpose of this utility model is to provide a kind of glow starter, and it can not rely on the tungsten filament of fluorescent tube and lights fluorescent lamp.

In order to achieve the above object, the utility model provides a kind of glow starter, its technical scheme comprises one first electrode and one second electrode that is connected with mains supply, the negative pole of this second electrode and one first diode, the positive pole of one the 4th diode, one first capacitor, linking to each other of one second capacitor, this first electrode and one the 3rd capacitor, one the 4th capacitor links to each other, the negative pole of the other end of the 3rd capacitor and the 4th diode, the positive pole of one the 3rd diode links to each other, the positive pole of the other end of the 4th capacitor and one first diode, the negative pole of this second diode links to each other, the positive pole of the other end of this first capacitor and this second diode, one end of one second resistance links to each other, the negative pole of the other end of this second capacitor and the 3rd diode, one end of one first resistance links to each other.

According to described glow starter, wherein, this first capacitor, second capacitor, the 3rd capacitor and the 4th capacitor are electrodeless dacron terylene condenser.

In the utility model, form the multiplication of voltage frequency multiplier circuit by non-linear element capacitor and diode, during application, this multiplication of voltage frequency multiplier circuit becomes the civil power of 50Hz the high frequency electric source of 15KHz-25KHz, the other end of first resistance and second resistance is used for linking to each other with the two ends of a fluorescent tube respectively, be connected with the two ends of fluorescent tube and light this fluorescent tube under the situation of tungsten filament not relying on by two resistance, so this fluorescent tube can not adorned tungsten filament.

From above-mentioned analysis as can be known, the utility model is simple in structure, and it is fast to light fluorescent tube, and light is stable, and manufacturing and application cost are low.

Description of drawings

Fig. 1 is the structure of the utility model preferred embodiment and uses schematic diagram.

The fluorescent tube structure schematic diagram of Fig. 2 for being used with the utility model preferred embodiment.

Embodiment

According to Fig. 1, Fig. 2 as can be known, 2 of a, b do not adorn tungsten filament in fluorescent tube, after connecting with the mains by starter circuit shown in Figure 1 in the leading point of fluorescent tube leading-out end c, d point and the fluorescent tube other end, fluorescent tube N just can light luminous, and light is stable.Electrode A links to each other with capacitor C3, C4, and the end of the negative pole of electrode B and diode D1, positive pole, capacitor C1 and the C2 of diode D4 links to each other.The other end of capacitor C3 links to each other with the negative pole of diode D4, the positive pole of diode D3, the other end of capacitor C4 links to each other with the positive pole of diode D1, the negative pole of diode D2, the other end of capacitor C1 links to each other with the positive pole of diode D2, an end of resistance R 2, the other end of capacitor C2 links to each other with the negative pole of diode D3, an end of resistance R 1, and the other end of resistance R 1, R2 joins with two of fluorescent tube N respectively.The power supply of 220V is from electrode A, B two ends input circuit, diode D1, D2, D3 and D4 are silicon rectifier diode, capacitor C1, C2, C3 and C4 are electrodeless dacron terylene condenser, diode D1, D2, D3 and D4 and capacitor C 1, C2, C3 and C4 constitute a multiplication of voltage double-frequency oscillation circuit, the frequency translation of civil power 50Hz is become 15KHz-25KHz, pass through current-limiting resistance R1 again, R2 delivers to the two ends of fluorescent tube N and removes to light fluorescent tube N, for the existing fluorescent tube that tungsten filament is housed, after the tungsten filament fusing, still can be used with the utility model, thereby saved resource, reduced user's application cost.Two resistance R 1, R2 play the effect that current limliting and stable fluorescent lamp are worked stably, make fluorescent tube N in that to light the back stable working reliable, brightness stability.

In sum, the utility model compared with prior art, have the following advantages and effect: simple in structure, manufacturing cost and use cost is all lower, even voltage still can work in the 150V-250V situation, lights fast, work and illumination are steady, long service life, the city of especially suitable rural area and low voltage and voltage instability is widely used.
