Abstract
The utility model relates to a fluorescent lamp electronic ballast, which is used for the ignition and the control of an electric discharge lamp. The utility model is also used for the ignition and the stabilization of the working voltage of a florescent lamp. The utility model is characterized in that a quadruple voltage circuit which is formed by the concatenation of two doubling circuits with opposite polarities is replaced by the assembly of a resistance-capacitance and a diode. The utility model not only has the advantages of an ordinary electronic ballast, such as fast starting, energy conservation, long service life, starting a fluorescent lamp with a broken filament, but also has the advantages of low cost, etc. The quality of mains supply can be improved because of the reactance of the utility model is capacitive.
Description
The utility model relates to a kind of circuit arrangement that is used for discharge lamp igniting or control, replaces traditional inductance type ballast and backing starter, the instantaneous ignition high pressure is provided and the operating voltage of reduction is provided after igniting to fluorescent lamp.
Present multiple electric ballast patented technology is open, respectively possess some good points as these technology such as CN9020018.6, CN89219461.8, also there is this series products to sell on the market, these products generally can both be saved the energy that igniting consumes, prolonging lamp tube service life, the fluorescent tube that can light fracture of wire that has, but its common defective is complexity of circuit, used device is many, so cost is higher.
The purpose of this utility model be disclose that a kind of circuit is simple, the few cheap and electric ballast of reliable operation of components and parts.
A kind of electronic ballast for fluoresent lamp has electric capacity, resistance diode, it is characterized in that entire circuit is four voltage-multiplying circuits that formed by two opposite polarity voltage-multiplying circuit serial connections; Each voltage-multiplying circuit is made of two electric capacity, two 2 utmost point pipes and a resistance: a termination of AC power is in parallel with electric capacity again after connecting with two diodes, connect again after the parallel connection circuit of a last resistance, the centre that the other end of AC power is received two diodes by an electric capacity; Two high-pressure sides of four voltage-multiplying circuits connect the two ends of fluorescent lamp.
The utility model is when fluorescent lamp is unignited, and energized produces the high direct voltage of four times of peak values of acs through several cycles in high-pressure side moment, and promptly 4
The high pressure of V, fluorescent tube is lighted, do not produce multiplication of voltage between high-pressure stage after the conducting, opposite resistance, the capacitance decompression of pass through, and make between two electrodes AC voltage drop to the operating voltage of fluorescent lamp plays and lights a fire and the effect of Control work voltage, circuit only is made up of several resistance, electric capacity, diode, low and the easy manufacturing of cost, the reactance of circuit is a capacitive, improves the power supply quality of electrical network.Direct-current discharge, light is stable, soft.
Below in conjunction with accompanying drawing, further specify by embodiment
Description of drawings:
Figure of description is the circuit diagram of embodiment.
Embodiment is the electric ballast of the fluorescent lamp of a kind of 40W.Then four shunt of the output terminals A of AC power: the firstth, electric capacity 1, the second, series diode 2,3, the positive pole of diode connects the A end, one, two liang along separate routes after the parallel connections again series resistance 4, the three be and the second reverse along separate routes series diode 5,6, the 4th is electric capacity 7, three, four liang of resistance 8 of connecting again after the parallel connections along separate routes, the other end B of AC power receives between the diode 2,3 by electric capacity 9, be connected on diode 5 by electric capacity 10, between 6, the terminal C of resistance 4 is the positive high voltage end, and the terminal D of resistance 8 is a negative high-voltage end, electric capacity 1,7,9,10 withstand voltagely are 400 volts, resistance 4,8 resistances are 10 ohm.
