Abstract

The utility model relates to an electrodeless high-frequency scanning neon lamp, comprising a glass lamp tube and a power supply circuit. The utility model is characterized in that both ends of the lamp tube are sealed; a layer of transparent conducting film is sprayed on the surface of the lamp tube; the conducting film is divide into at least two sections on the surface of the lamp tube; each section is provided with a conducting lead wire, and is switched on with the power supply circuit. Due to the metallic electrodes inserted into the tube from both ends, the phenomenon that the end part has chronic air leakage does not exist, extending the service life of the lamp tube obviously.

Description

Electrodeless high frequency scanning neon lamp

The utility model relates to a kind of neon light, particularly a kind of high frequency sweep neon light.

Known neon light all has metal electrode, because the coefficient of expansion and the thermal conductivity coefficient of glass and metal can not be in full accord, so in production process with in using, burst through the sealed portion position of being everlasting and damage fluorescent tube, even do not burst, because metal and glass hermetic seal fully certainly lead to chronic leakage, thereby reduce the life-span of fluorescent tube.In addition, when traditional neon light used, voltage was up to 15,000 volts, electric current 50 milliamperes, and 500 watts of power, dangerous big, can not miniaturization and enter household, and the shortage innervation.

The utility model patent communique that Patent Office of the People's Republic of China publishes, announce a key name and be called " stepping low pressure neon light " (application number: 91209928.3, notification number: utility application CN2095477U), this patent application proposes the improvement project to traditional neon light, big at traditional neon light power consumption, dangerous, do not have dynamic, can't miniaturization etc. defective improve, fluorescent tube adopts hard material glass tube, caliber can be as small as 2 millimeters, lamp tube electrode adopts the sealing-in of tungsten bar, at surface of the light tube spraying butter of tin coating, make surface of the light tube cover the layer of transparent conducting film, draw as electrode by lead, the sealing-in of tungsten bar electrode is called the single electrode neon light at an end of glass lamp.In addition, also produce high frequency voltage, thereby reduce the operating voltage of fluorescent tube, and to make output signal by logical signal control be the sawtooth voltage signal of oblique ascension step by step by impulse hunting.About 2,000 volts to 3,000 volts of the operating voltage of fluorescent tube, electric current is 50 micromicroamperes, the every rice lamp pipe of circuit power consumption used 500 hours, power consumption 1 degree.But, this scheme still has a metal electrode with the glass tube sealing-in at least, though adopt tungsten bar electrode and hard material glass, both coefficients of expansion differ slightly little, the airtight quality of lamp tube electrode increases, but still can't avoid the chronic leakage phenomenon around the metal electrode fully.

The purpose of this utility model, provide a kind of electrodeless high frequency sweep neon light that fully phases out (or any end) sealing-in metal electrode at the neon light tube two ends, because the neon light tube two ends seal fully, do not have the chronic leakage problem, so the life-span of the obvious prolonging lamp tube of energy.

The utility model is combined by neon light tube and lamp power supply.Fluorescent tube adopts in the glass tube and is coated with fluorescent material, be coated with dielectric outward, charge into micro-high-purity argon gas after vacuumizing, just form electrodeless neon light tube after burning mouth, the lamp power supply drops to 12 volts of voltages to 220 volts of alternating voltages by transformer, rectification becomes direct current, and the circuit that makes up through electronic component becomes high frequency voltage output.High frequency voltage by outer at least two components of fluorescent tube from conducting medium to fluorescent tube in gas produce ionization, gas transfers energy to fluorescent material, makes light-emitting phosphor.The lamp power supply can evenly rise between the 0-12 volt when high frequency voltage takes place, and this moment, neon light tube just produced the scanning effect.When if voltage rests on 12 volts, the just normal light yellow of fluorescent tube, if intermittently rise on (wave mode such as step), fluorescent tube just jumps forward.Sweep starting point can choose at random any point at fluorescent tube, and a plurality of starting points can be arranged, and is with countless changes.

The utility model does not need metal electrode, also just need not to carry out the sealing-in between metal and the glass, the problem that does not exist sealing-in place to burst can obviously improve the rate of finished products of product, and its rate of pressurization be any neon light tube can not compare therefore life-span of prolonging lamp tube greatly.Owing to use low-voltage generation high frequency voltage, there is not danger during use, and can miniaturization, make neon light can enter household.

Below in conjunction with the description of the drawings, provide embodiment of the present utility model.

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

Fig. 2 is a power circuit diagram of the present utility model.
