Description

Multifunctional electronic starter

The utility model belongs to electronic starter for fluorescent lamp.

The electric ballast of Xiao Shouing is a lot of in the market, mostly adopt electronic circuit directly to be concatenated in the mains circuit, its electronic ballast output end and fluorescent tube join, omitted the ballast made from the iron core silicon steel sheet, make that the fluorescent start circuit is simple, easy to install, but its weak point is this kind electronic starting circuit starts weak effect, fluorescent lamp illumination is low, and starting current is big, and lamp tube service life shortens, because circuital current is bigger, device is fragile, and the entire circuit life-span is short, the characteristic instability.

For solving above deficiency, the purpose of this utility model provides a kind of multifunction electronic starter, utilize diode and capacitor to form, be connected between ballast and the fluorescent tube, effectively solved fluorescent lamp low pressure, cold-starting and fluorescent tube and damaged the problem of utilizing.

Structural design of the present utility model is achieved in that in a close insulation shell of envelope electronic circuit board is housed, form by four diodes and two capacitors on the wiring board, housing one end has two inputs, one end and mains supply wherein an end join, another input joins with the output that is connected in series ballast, two outputs of housing are directly carried the limb that connects the fluorescent lamp two ends on the arm, and the limb at two ends is short circuit separately, its circuit connects: output of ballast (as shown in Figure 2) and diode D1 negative terminal, capacitor C1 and capacitor C2 join, capacitor C1 is in parallel with diode D1, diode D1 anode and diode D2 anode join, draw an output simultaneously and be connected to one of fluorescent tube end, diode D2 is connected in series with diode D3 homophase, diode D3 negative terminal joins with capacitor C2 one end and diode D4 negative terminal, draw an output simultaneously and fluorescent tube other end limb joins, diode D2, point is another input of mains supply among the D3.Two limbs of fluorescent tube two ends of fluorescent lamp are short circuit separately, joins with circuit two outputs respectively.

Detailed structure of the present utility model is provided by embodiment and accompanying drawing.

Fig. 1 is a multifunction electronic starter shape assumption diagram;

Fig. 2 is a multifunction electronic igniter circuitry structure chart;

Its circuit is by shown in Figure 2,2 is ballast, input is a power input, output is connected with one of D1, C1, C2 end, and the D1 anode is connected with one of fluorescent tube end, is connected with the anode of C1, D2 simultaneously, the D2 negative terminal is connected with the D3 anode, the C2 of D3 negative terminal and electric capacity and D4 negative terminal join, and are connected with the fluorescent tube other end simultaneously, and the D4 anode connects with one of D1 negative terminal, capacitor C 1 and C2 end.Diode is 1N4007 in the circuit, and capacitor is 1～1.5 μ F/450Y, and two outputs of circuit join respectively with after the shorted on both ends of fluorescent tube.

Operation principle:

A, b two ends are 220 volts of AC power.When a end for just, then electric current is flowed through diode D4, fluorescent tube M, diode D2 to power supply b end formation loop, at this moment, capacitor C1 is recharged, Vc1 ≈ 220V, its polarity as shown in the figure.

When a end when negative, then b end is for just, electric current is by the b diode D3 that flows through, fluorescent tube M, diode D1 constitute the loop to power supply a end, and at this moment, capacitor C2 is recharged on the one hand, Vc2 ≈ 220V, on the other hand, capacitor C1 will be by power supply to fluorescent lamp M discharge, and this moment, fluorescent tube M two ends obtained about 440 volts voltage.

The advantage of the utility model, circuit structure is simple, can make to wear out, and the disconnected fluorescent tube of filament continues to use, and low electricity too low temperature can start, and improves illumination, can light simultaneously two tubes, economizes on electricity, and is easy for installation, is a kind of comparatively ideal fluorescent lamp starter.
