Abstract
The utility model provides a special-purpose electronic booster device for a fluorescent lamp, comprising a change-over switch, and a full-wave rectifying circuit which is composed of rectifying diodes and voltage doubling capacitances. The utility model has strong adaptability of the voltage of electric power source and load, and the open circuit and short circuit of the load can not burn out the elements. The utility model can save the electric power source by 30% and has the advantages of simple circuit, less elements, low cost, convenient installation, low rate of failure, long service life, stable working performance, no noise, no flicker, and normal work in the voltage range of 120 to 300V. The utility model can be used on wasted fluorescent lamps without the failure of gas leak, and filaments breaking off fluorescent lamps.
Description
The utility model relates to a kind of servicing unit of fluorescent lamp, especially a kind of fluorescent lamp special electronic stepup transformer.
Because the high speed development of economic construction, supply of electric power is generally tight slightly, and especially, home-use fluorescent lamp often opens not bright because of supply voltage is on the low side, influenced user's normal study and work peak times of power consumption during this period of time in the ten nine o'clock to 23 evening.Adopt the voltage regulator pressure regulation, then increase the loss of voltage regulator, the fluorescent lamp starter of Xiao Shouing then exists luminous efficiency low in the market, or the cost height, deficiency such as is not easy to popularize.
The purpose of this utility model provides that a kind of circuit is simple, element is few, cost is low, safe and convenient to use, and the life-span is long, the fluorescent lamp special electronic stepup transformer that power saving capability is strong.
Full-wave rectifying circuit and change over switch that this fluorescent lamp special electronic stepup transformer is made up of rectifier diode, multiplication of voltage electric capacity are formed.
Further describe below in conjunction with accompanying drawing.
Fig. 1 is the utility model basic circuit diagram.
This fluorescent lamp special electronic stepup transformer is made up of boost part and change over switch.Boost partly is by rectifier diode D
1, D
2And multiplication of voltage capacitor C
1, C
2The two multiplication of voltage full-wave rectifying circuits of forming, change over switch K is as boosting or the conversion of pass-through state, and switch is pulled to the shelves that boost when supply voltage is low, and mains switch just often switch is pulled to straight-through shelves.
The operation principle of this stepup transformer is: when supply voltage is positive half cycle (on just down negative), electric current is by K, D
1, C
1The lower end constitutes the loop, at C
1On just be filled with negative down voltage; When supply voltage was negative half period (just going up negative down), electric current passed through C
2, D
2, K upper end constitutes the loop, at C
2On just be filled with negative down voltage, V
C1, V
C2Voltage after the series connection is two ones of supply voltage, and this voltage is transported to fluorescent lamp, and it is bright that fluorescent lamp can normally be opened under low-pressure state.
This fluorescent lamp special electronic booster circuit is simple, element is few, be convenient to install, safe and convenient to use, failure rate is low, life-span is long, strong to supply voltage adaptability, can be in the 120V-300V voltage range operate as normal, power saving capability is strong, under equal brightness, after using stepup transformer, economize on electricity 30%, prolonged the life-span of fluorescent tube.Strong to the adaptive load ability, load open circuit, short circuit can not burnt element, stable work in work, noiseless, flicker free during illumination.This stepup transformer is divided into two kinds of specifications: a kind of 6-11 of being applicable to watt of light reading lamp that uses Inductive ballast; Another kind is applicable to 15-40 watt of inductance ballast formula fluorescent lamp.When using the fluorescent lamp of band starter, turn on the power switch and find ceaselessly bounce flash of starter, can not open bright, at this moment as long as the anti-turnback of starter just can normally have been lighted (also can not wanting starter directly opens bright).This booster circuit adopts two capacitors, has increased the capacitance of circuit, has improved the active power of power supply.Waste and old fluorescent tube is so long as less than what leak gas, and the light pipe of the filament that broken can use.
