Description

The electrodeless fluorescent lamp glow-starting ballast

The utility model belongs to the electronics glow-starting ballast, more specifically relates to a kind of electrodeless fluorescent lamp glow-starting ballast.

The fluorescent tube that uses has the heating tungsten filament at two at present, and disconnected when a tungsten filament one, fluorescent tube does not just work.In the process of using fluorescent lamp, the someone has found out that end of a kind of stature tungsten filament that broken with lead short circuit outside pin, makes circuit become the loop, but has only the not disconnected tungsten filament heating of an end, fluorescent tube is lighted, but starting time is long, because have only the relation of tungsten filament heating on one side, after using a period of time, other one tungsten filament has broken, and this fluorescent tube can not be used, and the starter that has is bad, the voltage that has is lower than 180V, and fluorescent tube can not be lighted.

The purpose of this utility model has provided a kind of electrodeless fluorescent lamp glow-starting ballast, does not have silk in the fluorescent tube, and cost is low, and is simple in structure, lights fast, bright stable.

In order to reach above-mentioned task, the utility model by the following technical solutions: do not adorn tungsten filament at fluorescent tube N two, by capacitor C ₁-C ₄, diode D ₁-D ₄Multiplication of voltage, frequency multiplication that non-linear element is formed become 15KHz-25KHz with electric 50Hz, pass through resistance R ₁An end, resistance R ₂An end link to each other with two of electrodeless fluorescent lamp pipe N respectively.

Fig. 1 is an electrodeless fluorescent lamp glow-starting ballast structural representation.

Fig. 2 is the fluorescent tube structural representation.

Below in conjunction with accompanying drawing the utility model is described in further detail:

According to Fig. 1, Fig. 2 as can be known, 2 of a, b do not adorn tungsten filament in fluorescent tube, and at fluorescent tube leading-out end c, d point receiving electrode, at the leading point of fluorescent tube other end receiving electrode, after connecting with the mains, fluorescent tube just can be lighted luminous, and light is stable.A of electrode and capacitor C ₃, C ₄Link to each other other end B and diode D ₁Negative pole, D ₄Positive pole, capacitor C ₁An end, C ₂An end link to each other.Capacitor C ₃The other end and diode D ₁Negative pole, diode D ₃Positive pole link to each other capacitor C ₄The other end and diode D ₁Positive pole, diode D ₂Negative pole link to each other capacitor C ₁The other end and diode D ₂Positive pole, resistance R ₂An end link to each other capacitor C ₂The other end and diode D ₃Negative pole, resistance R ₁An end link to each other resistance R ₁, R ₂The other end join with two of electrodeless fluorescent lamp pipe N respectively.The power supply of 220V is from A, B two ends input circuit, D ₁-D ₄Be silicon rectifier diode, C ₁-C ₄Be electrodeless dacron terylene condenser, diode D ₁-D ₄With capacitor C ₁-C ₄Constitute a multiplication of voltage double-frequency oscillation circuit, the frequency translation of electric 50Hz is become 15KHz-25KHz, pass through current-limiting resistance R again ₁, R ₂Deliver to two of electrodeless fluorescent lamp pipe N and remove to light fluorescent tube N.Two resistance R ₁, R ₂Play current limliting and stable electrodeless fluorescent lamp is worked stably, make electrodeless fluorescent lamp pipe N in that to light the back stable working reliable, illumination is steady.

The utility model compared with prior art has the following advantages and effect: simple in structure, cost is low, electricity Be pressed in the 150V-250V situation and work, light soon, work and illumination are steady, long service life, especially Face width is used in the city that is fit to rural area and low voltage and voltage instability, has widely society and economic benefit.
