Description

Electronic frequency-changing starter for fluorescent lamp

The utility model relates to a kind of fluorescent lamp frequency conversion starter.

Because the extensive use of fluorescent lamp makes people seek the electric ballast that high efficiency is utilized fluorescent lamp, reducing the requirement of starting resistor, and fluorescent lamp is played the certain protection effect to electrical network.

The purpose of this utility model be design a kind of can prolonging lamp tube service life, improve luminosity, economize on electricity significantly, and the electronic fluorescent lamp frequency conversion starter that the useless fluorescent tube of the filament that broken is recovered lost eyesight.

The utility model is realized above-mentioned purpose with following architectural feature: the useless electronic fluorescent lamp frequency conversion starter of this energy-efficient profit is made up of frequency converter and starter two parts, and frequency converter comprises circuit and step-up transformers such as electronics step-down, rectified wave filter, the higher-order of oscillation, triggering.Electronics step-down, rectifying and wave-filtering, high-frequency oscillating circuits links to each other with the elementary order of step-up transformer, and circuits for triggering output signal termination high-frequency generator input, starter come down to the voltage-multiplying circuit that is made of electric capacity and diode.

The 50HZ alternating current that comes by economizing on electricity becomes the direct current about 80-120V after step-down, rectification, filtering, high-frequency oscillating circuits is through trigger circuit triggers, produce the higher-order of oscillation, high-frequency ac voltage in the secondary generation of high frequency transformer reaches more than the 260V, after the starter multiplication of voltage, produce high voltage, start fluorescent light emitting tube.When supply voltage fluctuateed in 100-350V, it was normally luminous to use the utility model that fluorescent tube is started, and light is fair and clear soft, flicker free, and the luminous efficiency height, easy for installation, it is luminous to promote 6 40W fluorescent lamps simultaneously.Believe the utility model energy-conservation, improve the luminous efficiency aspect and will give full play to its effect.

Provide embodiment below in conjunction with accompanying drawing:

The useless electronic fluorescent lamp frequency conversion starter of this energy-efficient profit of Fig. 6 starts the fluorescent lamp wiring schematic diagram.

Frequency converter is made of electronics step-down transformer, current rectifying and wave filtering circuit, high-frequency oscillating circuits, step-up transformer and circuits for triggering in the utility model, the electronics step-down transformer is by bidirectional triode thyristor SCR1, bidirectional diode D1, resistance R 1, potentiometer W1 constitutes, current rectifying and wave filtering circuit is made of D2-5 and C2, high-frequency oscillating circuits is by inductance L, controllable silicon SCR 2, capacitor C 1, C3, the elementary formation of resistance R 2 and high frequency transformer B, circuits for triggering are made up of time-base integrated circuit NE555 and peripheral circuit.Exchange economize on electricity through regulating circuit output 70-100V alternating current, behind rectifying and wave-filtering, form 80-120V direct current, the power supply during as inversion.When controllable silicon SCR 2 not during conducting, to capacitor C4 charging, the charging current transformer B1 that flows through is elementary, goes out alternating current at secondary induction through inductance L for power supply.When trigger impulse arrived, the electric charge on the C4 was through SCR2 and B1 is elementary bleeds off.

Starter comes down to voltage multiplie, produces very high voltage and force the fluorescent tube conducting luminous before fluorescent tube starts.The high frequency ac signal of frequency converter output connects the cd end as the input signal of starter, after the fluorescent tube conducting is luminous, and the drop of output ef terminal voltage, voltage-multiplying circuit just plays metering function.Starter among Fig. 3 is made of diode D9, D10 and capacitor C9, C10, and electric capacity common port and diode mid point are input cd, and the diode two ends are output ef.Circuit shown in Figure 4 is a kind of slow starter.Form multiplication of voltage by D9, D10, C9, C10 when just beginning, make the faint conducting of fluorescent tube, temperature raises in the pipe, and impedance reduces, and D11, D12 conducting are worked, and fluorescent tube brightens normally luminous, and C11 plays metering function.This circuit is a multiplication of voltage bridge rectifier.

Starter in the utility model can be made disk as shown in Figure 5.The electrode column at two hole dimensions in middle part and fluorescent tube two ends adapts.Cd termination inverter output terminal, ef termination fluorescent tube other end electrode column.The mode of connection of the present utility model as shown in Figure 6, frequency converter is connected across economize on electricity and comes on the line, each fluorescent tube is attempted by on the power line, every tubes is by K switch independence control switch.Each frequency converter can drive 6 40W daylight spots.Except that economize on electricity 30-35%, have the high characteristics of luminous efficiency, light is fair and clear soft, and flicker free, prolonging lamp tube service life be more than 2 times, and in addition, but changing waste into valuable also makes the fracture of wire fluorescent tube luminous again.
