Abstract

The utility model relates to an electronic ballast for fast starting an energy-saving fluorescent lamp, belonging to the technical field of electrical equipment illumination. The utility model adopts a circuit which is composed of discrete components diodes from D1 to D6, capacitors from C1 to C5, and resistors R1 and R2. When the power supply is switched on, the capacitor C2 is charged instantly, positive 600V voltage is generated at the A end filament of the fluorescent lamp, the capacitor C1 is charged, negative 400V voltage is generated at the B end filament, and the fluorescent lamp can be quickly started in 0.1 second under the direct current high voltage. After the electric discharge of the C1 and the C2, voltages at both ends of the fluorescent lamp are 110V. Because current limiting of the resistor R1 which is connected in parallel with the both ends of the power supply, the maximum working current is less than 200 mA. The application range of the voltage is broad, and the utility model can be used within the range from 110V to 250V. The utility model is especially suitable for fluorescent lamps from 20W to 40W, and has the advantages of a few electronic components, high reliability, and good energy saving effect.

Description

Start the energy-saving daylight lamp electric ballast fast

The utility model starts the energy-saving daylight lamp electric ballast fast and belongs to the electrical lighting class.

The electric ballast that present all kinds of fluorescent lamp adopted, majority are the independent-excited inverter circuits that adopts bidirectional diode to trigger.In the starting of oscillation process, the high voltage narrow pulse that is caused by trigger impulse repeatedly is added on the cold conditions filament, has caused on the filament emitting material to launch in a large number, and lamp tube ends is turned black in early days.Reduce and make the life-span.For this reason, must add that electronic starter gives lamp a constant heating current, scabble simultaneously in the narrow arteries and veins of high pressure.Like this, just made present electric ballast comparatively complicated in the use, the electronic devices and components of usefulness are more, the cost height, and poor reliability has been subjected to considerable restraint on applying.

The purpose of this utility model is to adopt simple and practical circuit, uses less electronic devices and components, makes fluorescent lamp fast starting, energy-conservation, reaches highly versatile, reliability height, delicate structure, easy to use, easy to utilize.

The technical solution of the utility model is: C2 charging after the energized, on R2, produce a positive direct voltage, and be added in the A end of filament.After C3, C4, C5 charging D5, D6 rectification, D4 charges to C1, produces a negative direct voltage through D1, D4; be added in the end of B in addition of filament; for preventing that electric current from burning fluorescent tube, protect other electronic devices and components, do not generate heat; negative terminal at D2 connects a resistance R 1; D5, D6 play buffer action, prevent other electronic component short circuits, energized moment C1, C2 charging; produce a direct current voltage at fluorescent tube A, B, two ends, make fluorescent tube moment fast starting.Its circuit connecting relation is: an end of alternating current 220V power supply rises with the negative terminal of C2, D2, the anode C1 of R1, D1 and is connected, D2, D3, R2 series connection are connected with the A end filament of fluorescent tube DG, capacitor C 2 is connected in parallel on D2, the D3, D5 just terminate at D2, D3 the series connection between contact on, D5, D6 series connection, D1, D4 series connection back is in parallel with C1, is being connected with DGB end filament, and the negative terminal of D6 is connected on D1, the D4 contact between connecting; The other end of power supply connect R1, C5, C4, C3 and on the contact between the other end of C5, C4, C3 is connected on anode, the D5 of D5 respectively and D6 connects, the negative terminal of D6.

Be that printed circuit board (PCB) is housed in socket on the structure, the circuit that electronic devices and components capacitor C 1-C5, diode D1-D6, resistance R 1, R2 form is housed on printed circuit board (PCB), and two contacts of fluorescent tube one end hold with lamp base A by bulb holder hole that contact is connected, the other end two contacts of fluorescent lamp are connected with lamp base B terminated line.

Advantage of the present utility model and good effect be, the electronic devices and components of use are few, reliability is high, and starting speed is fast, no stroboscopic and noise, and it is wide to adapt to voltage range, and consumed power is little, and good energy-saving effect is arranged.
